POPULATION AND OCCUPATIONAL CHANGE IN A COASTAL VILLAGE
Kistanto, Nurdien H.
Population; occupation; Central Java coastal village; migration; work force; agriculture; industry.
In “Sumbersari” there are three major types of productive work: rice farming , fish raising and factory work. The industrial estate which has been operating since the late 1970s has altered the pattern of employment, in part because the agricultural land previously used for rice fields and brackish water ponds has been converted to industrial use. Waves of migrants from other places have taken up residence in Sumbersari either on a temporary or a permanent basis. These migrants have contributed to population growth and comprise he bulk of work force in this village.

“Arad” (Otter Board Boat Seine), Hooped TEDs
The use of TEDs on the “Arad” (Otter Board Boat Seine Net) has never been done by fishermen from the northern part of the Java Sea in Central Java. In order to introduce this net and also to anticipate the shrimp embargo by World Trade Organization (WTO. TEDs construction used in this study was Hooped TEDs with LxBxD dimension of 60x 40 x 60 cm; width of grids deflector of 5 cm) . This construction made an angle of 45°. Fishing operation with and without TEDs was done 9 times during the day. Shrimp, fish, others and garbage entering the net were measured in terms of body weight and fish body circle was also measured in order to compare the result of each treatment. Both nets (with and without TEDs) contained Shrimp (Metapenaeus sp), Pilot-fish (Selaroides sp), Mackerel (Rastrelliger sp), Hair-tails (Trichiurus sp, Pony-fish(Leiognathus sp), others and garbage. The average catch every hauling for the net with TEDs were : Shrimp 1.17 kg; Fish 1.66 kg; others 0.14 kg and garbage 0.1 kg; whereas the net without TEDs were : Shrimp 1.09 kg; Fish 2.33 kg, others 0.34 kg and garbage 1.31 kg. The average body circle of fish caught by net with TEDs was 4.0-7.4 cm and those caught by net without TEDs was 4.0-8.9 cm. The amount of fish and garbage caught by using each treatment differed very significantly, while the amount of shrimp caught did not.

Susanto, Eko
dried fish products, glass transition, water activity, water content, shelf life, quality
Some traditional fish products in Indonesia have potential opportunity for global market, such as fish crackers, dried fish, ikan kayu (‘katsuobushi’) and dried pempek (traditional fish product from Palembang). Study on such products based on its glass transition temperature is still rare. On the other hand, glass transition phases of dried product play an important role in determining food stability because it can give an overview of physicochemical properties of the products. Using its glass transition temperature, dried fish product can be estimated for its shelf life. The purposes of this research are to observe the relation between some physicochemical properties of glass transition temperature of some dried fish products and its water content/water activity to the self life of the products. Dried fish products used were: fish cracker, dried-salted fish, ikan kayu (katsuobushi), fufu (very dried-smoked fish) and dried pempek. The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). The sample were taken using purposive sampling method. The method used for analysis of glass transition temperature was DSC method (Differential Scanning Calorimetry), and for water content and water activity were analysed using Aw meter and Moisture analyzer. All samples were analyzed in duplo. Research method used was experimental laboratory with research design of Completely Randomised Design. The experiment was conducted from August 2008 to December 2008 at Fish Product Processing Laboratory, Fisheries Department, Faculty of Fisheries and Marine Science – Diponegoro University, Food Engineering Laboratory – SQU, Oman. The results showed that different sample with different characteristics on physicochemical properties give different in water activity and also water content. The lowest water activity was performed by dried pempek. Glass transition temperature (Tg) of the products was very depend on the water content. The Tg of samples was ranged between 38.4oC – 76.4oC. The water content of the products ranged between 8.28%-37.28%. The Aw of the product was ranged between 0.57 – 0.87.

Mucus, Tilapia, histochemical analyzes
Mucus is one of a non-specific defense mechanism, since this is the first element of aquatic organisms, which contact physically, chemically, or biologically with the environment. The mucus self defense mechanism investigation was carried out on fresh water fish tilapia (Oreochromis mosambicus). Eight (8) types of lectine were used to examine residual carbohydrate-based protein from mucous component based on histological and histochemical observation method. The review was directed as basic information for detail review about physiology adaptation aspects.
The results showed that mucous in goblet cells from palatal, gills primary lamella, ecophagus and skin reacted with WGA (Wheat Germ Aglutinin) lectine. In another part, mucous from the goblet cells in palatal and esophagus cells reacted with PNA (Peanut Aglutinin). Based on these results, therefore, it can be concluded that mucous from goblet cells in esophagus contains residual of N-asetil glucosamine and/or similar acid β-galactose and α-N-acetyl galactomine. Mucous from goblet cell in palatal contains residual of X-acetyl glucosamine and/or sialat acid and galactose. While mucous in the gills lamella contains carbohydrate residual, namely N-acetyl glucosamine and/or sialat acid

The Coral Reef Rehabilitation and Management Program (COREMAP) is a 15-year program of theGovernment of Indonesia. It has been working at several sites in Indonesia since 1998 to achievesustainable use of coral reefs through the delegation of management authority to local communities.The establishment of effective models for participatory and community-based management is the core ofthis program. The model for community-based management includes community participation,community capacity building, promotion of alternative income generation, establishment of coral reefmanagement plans, community marine sanctuaries and community reef watcher programs. This paperdescribes the experiences and lessons learned in Phase I of the COREMAP Project in implementingcommunity-based reef management at Senayang and Lingga Islands, Riau Province. It is argued thatthe involvement of the community in the planning and implementation process of coral reef managementwill improve the management and conservation of coral reef ecosystems. It is hoped that the Indonesianexperience will contribute to the comparative literature on coral reef management.

HOW DISTRIBUTIONAL CONFLICTS THEORY EXPLAIN FACTORS AFFECTING INSTITUTIONAL CHANGES IN CORAL REEF GOVERNANCE? LESSONS LEARNED FROM GILI INDAH VILLAGE, WEST LOMBOK INDONESIA
Hidayat, Aceng
institutional change, governance structure, credible commitment, distributional conflict, power resources
This article aims at explaining factors affecting the successfulness of coastal communities of Gili Indah in constructing a governance structure of coral reef management. Coral reef management in this region has changed from an ineffective state regime to a local governance. From the perspective institutional economic theories, the emergence of a governance is an institutional change phenomena that are affected, among others, by actors’ characteristics such as organizational experiences, opportunistic behavior, environmental awareness/perception, planning horizon, bargaining power, technological skill and certainty; and trust, distrust and reputation. Using a distributional conflict theory of institutional change, the results of this research can draw a conclusion that institutional change process of coral reef management in the locality was strongly assumed affected by those factors.

THE EFFECT OF VARIOUS SPAT COLLECTOR MATERIALS FOR SPAT ATTACHMENT OF PEARL OYSTER (Pinctada maxima)
Arini, Endang
Putra Jaya, Nur Taufiq Syamsudin
Pearl Oyster (Pinctada maxima); spat; collector; settlement; endurance Test.
Early stage development of pearl oyster spat was very critical, hence spat required suitable substrates for their settlement to complete their metamorphosis. In this stage, byssus for the attachment is vulnerable and easy to break if there are some disturbance e.g. water movement, hence spat easily falling onto the bottom layer which may have various dirt materials leading to the dead of the spat. In the pearl oyster culture spat collector is important. The aim of this study is to study the effect of different collector materials to the number of spat settled, to reveal the best collector materials and the endurance of spat at the collector. This study was conducted in PT Autore Pearl Culture, at Sumbawa island, Nusa Tenggara Province. Materials used in this research were collectors of different substance i.e. asbestos (A), bamboo (B), polyethylene and roof ceramic (D) substance. The method used was laboratories experiment with Completely Random Design by 4 treatments and 3 replications. Data taken were the number of spat settlement, endurance test, and water quality. Data tested with Analysis of Variance (ANOVA) and further tested with Duncan Duplicate Regional test. Water quality was analyzed descriptively. The results showed that different collector materials performed a high significantly difference (p<0.01) to the number of spat settled. The best settlement reached by polyethylene [106±3.61 ind. (dm2)-1] followed by bamboo [40±3.61 ind. (dm2)-1], asbestos [16±2.52 ind. (dm2)-1] and roof ceramic [15±3.61 ind. (dm2)-1]. The endurance test indicated that percentage of lowest detached of spat from collector reached by treatment B (10.23%), followed by C (11.12%), D (46.95%) and A (50.60%). Water qualities during study were appropriate for the life and growth of pearl oyster spat.

THREATS TO THE MANGROVES OF THANE CREEK AND ULHAS RIVER ESTUARY, INDIA.
Borkar, MU.
Quadros, G.
Athalye, R.P.
Threats to Mangroves, anthropogenic activities, Thane creek, Ulhas river estuary, lndia.
The mangroves have adapted themselves best in the shallow sea coast, sheltered estuaries and deltaic:ones ofthe tropics and subtropics with characteristic environmental conditions vi:. temperature ranges between 200 C to 300 C, moderate to high monsoon precipitation i.e. [000 — 3000 mm/ annum, high humidity but with coastal aridity. On the sea-land intedace in global mangrove systems, there are gradual, slow or quickly changing ecological or geomorphological conditions to which mangroves have to adapt. The human thrust or pressure, other biotic factors and interactions also cause changes in mangrove ecosystems. Due to this the mangroves are now very dynamic but have become fragile through out the globe. Mangroves have various adaptations to cope with the stress to which they are subjected and jbr these adaptations they have to expend a lot of energy. Increased salinity has brought about floristic changes in the mangroves, particulariv in growth, form and structure of plant parts such as pneumatophores. thickening of leaves, salt extruding glands, viviparity stunted tree growth of some species and changes in plant communities. The mangrove forests stand as a barrier between the land and the sea and are jeeding and breeding grounds for dgferent fishery organisms. The mangroves if the world especiallv of the Indian continent are threatened and are on the verge of losing their identity. The study on the distribution of mangroves and the associate plants along Ulhas river estuary and the Thane creek during the period September 200] to August 2002 showed presence of 8 genera and I4 species ey' mangroves and I I genera and I2 species ry mangrove associates. The dominant mangrove type was Avicennia marina where as Acanthus ilicyblius was the mtyor associate type. When compared with the earlier data it was apparent that the mangrove cover was signtficantlv reduced The main threat to mangroves was due to anthropogenic activities, like cutting for jitel; reclamation for various purposes such as industry, agriculture, sand landing (reti-bunder), solid waste dumping, aquaculture ponds, construction of housing colonies, roads and bridges violating the CRZ regulation. There is an urgent need to conserve the mangroves of this region; which can be achieved through education, motivation of local people and strict supervision by administrative bodies and non-government organi:ations

Marine fisheries productivity has been studied in North coast of central Java. Study was carried out at four coastal regions, i.e Brebes, Pemalang, Jepara , and Rembang from July to October 2002. The primary and secondary data were collected covering the existing marine habitats, namely mangrove, sea grass meadows, coral reefs, and fishing and marine culture production. The result showed that most marine local habitats in the North coast of central Java, mainly in the studied sites were worse. Mangrove cover, from the total of 3,442.19 ha was only 979,8 (8,46%) in good condition, while remaining areas of 2,462,39 ha (71,54%) were in critical or bad condition. Similar trends were observed in the sea grass and coral reef habitats showing the decrease of living coral cover resulted in the decline in fishing capture production.

COASTAL TOURISM DEVELOPMENT: GUIDING PRINCIPLES FOR SUSTAINABLE DEVELOPMENT
Davis, Derrin
The paper is based on the preparation by the author and two colleagues1 of a report on principles of sustainable development in Australia’s coastal zone, with a specific focus on the tourism industry. That report, prepared with funding under Australia’s Coastal Action Program, and following public comment and revision, has recently been published by the Australian Government under the title Coastal Tourism: A Manual for Sustainable Development (Commonwealth Coastal Action Program, 1997).
The coast is an important part of the tourism industry’s attraction and resource base in Australia and many other countries. It is concluded that sustainable development and use of the coastal zone is crucial to the long-term profitability of the tourism industry and the quality of life of local citizens. The stage of the development process – from feasibility to operation and management – are each considered of importance to sustainable tourism developments. A number of guiding principles for such developments are spelled out in the paper, and issue such as self-regulation and the reasons that developers should consider sustainability in their activities are addressed. Additionally, reference is made to case-studies of sustainable tourism development that have occurred in Australia in recent years, and the lessons from those developments described.
The key recommendation arising is that a valuable contribution to protecting coastal assets – assets upon which the tourism industry and the community depend – will arise from the formulation of environmental, social and economic criteria that developers can consider in planning, constructing and operating tourism ventures in the coastal zone.

The white spot syndrome virus (WSSV), the causative agent of White Spot Syndrome Disease (WSSD), is a major shrimp pathogen in Indonesia. Dendronereis spp. is a ubiquitous Polychaetes and natural food of shrimp raised in brackishwater pond in Indonesia. The objective of this research is to determine the occurrence of WSSV and the viral load in Dendronereis spp. obtained from the shrimp pond. Dendronereis spp. was obtained with PVC (10 cm in diameter) from a traditional shrimp pond in Semarang vicinity. As a comparison, healthy looking Penaeus monodon was also obtained from the same pond. The occurrence of WSSV in Dendronereis spp. was determined with 1-step and nested PCR using primer for WSSV major envelope protein, VP 28. The viral load was counted with 1-step Real Time PCR. The WSSV was detected in Dendronereis spp. with 1-step and nested PCR. The point prevalence of WSSV infection in Dendronereis spp. is 90 %. The viral load ranged from 0 to 1.9 x 104 copy of DNA/µg total DNA. The viral load in Dendronereis is comparable with that of naturally infected and at carrier state P.monodon from the same pond. This is the first report of WSSV load in naturally infected Dendronereis spp.

growth inhibition, marine bacteria, sponge Aaptos sp., resistant bacteria
The improper and uncontrolled uses of antibiotics against pathogenic bacteria have resulted in
the occurrence of Multi Drugs Resistant (MDR) strains. There is now an urgency to find alternative
antibiotics to combat the MDR strains. Sponge associated microorganisms are among of the most
interesting and promising marine natural product sources, which produce polyketide and non
ribosomal peptide products with various biological activities. In this study, marine bacteria were
isolated from sponge Aaptos sp. collected from North Java Sea, and were screened for antibacterial
activity against MDR strains. Three out of 64 bacterial isolates were successfully screened and were
found to be active against MDR strains, in which 2 isolates (SPA1 and SPA5) were active against
resistant strain Escherichia coli and 1 isolate (SPA21) against resistant strain Proteus sp., respectively.
These active isolates were also capable of amplifying NRPS gene fragments necessary for the
biosynthesis of non ribosomal peptides. The identification results revealed that the active isolates are
Halomonas aquamarina, Alpha proteobacterium, and Pseudoalteromonas luteviolacea

FISHERIES REGULATION AND ENFORCEMENT IN INDONESIA, MALAYSIA AND THE PHILLIPINES
Susilowati, Indah
Non compliance incidence in the fisheries of Indonesia, Malaysia and the Philippines were found relatively high. The fisheries management is effectively applied when compliance is attained. In order to secure the compliance enforcement and surveillance are needed. In fact, enforcement is costly. This paper suggests adopting the ‘cheap’ enforcement and surveillance strategy using co-management approach.

ACCUMULATION OF ALUMINIUM IN THE TISSUE OF GIANT FRESH WATER PRAWN (Macrobrachium rosenbergii de Man) EXPOSED TO ACIDIC WATER CONTAMINATED WITH ALUMINIUM SALT
Redjeki, Sri
water acidification; aluminium toxicity; fresh water prawn; accumulation of aluminium
Aluminium is known as competitive trivalent and its occurance in an acidic environment causes ionic disturbances in aquatic invertebrates and crustaceans. An investigation was conducted to determine the accumulation of aluminium in the tissue of giant fresh water prawn (M. rosenbergii de Man) exposed to acidic water (pH 5.0) and more alkaline media (pH 6.5) contaminated by aluminium salt (0.3 mg/l of nominal concentration of Al). A static test with regular water exchange was employed during the experiment.
The first moulting was recorded in all treatments at the first week of the investigation. Normal moulting period, i.e. 6 – 8 days after the first moulting was observed in 55% of prawns in the media with normal pH (pH 6.5). A longer period, more than 10 days, was needed by prawn in the media at pH 6.5 with 0.3-mg/l aluminium, pH 5.0 and at pH 5.0 with 0.3 mg/l aluminiun. The third moulting was only recorded at prawn in media at pH 6.5. The elevated aluminium in the acidic media caused the highest mortality rate and there was no mortality recorded at normal pH. Most of the mortality was observed before and soon after moulting.
The elevation of 0.3 mg/l aluminium in the more acidic water (pH 5.0) increased the aluminium and decreased the calcium concentrations in the prawn tissue. However, the magnesium in the prawn’s tissue showed its highest consentration at pH 5.0 with 0.3-mg/l aluminium.
The decrease of calcium concentration in the prawn’s tissue was always followed by the increase of concentration of aluminium significantly (P < 0.01). This suggests that the aluminium interfers the intake of calcium from the media by the prawn. However the magnesium intake was not affected. As a conclusion, the elevated level of aluminium in the acidic media increased the accumulation of aluminium in the prawn’s tissue and influenced the moulting behaviour of the tested prawn by interfering the absortion of calsium and magnesium, i.e. decreasing the calcium and increasing the magnesium concentrations in the prawn tissue.

Antifouling paints, Macro-biofouler, Marine Net cage
Macrofouling is one of the major problems on a marine net cage culture. The attachment of macrofouling could cover the net cage and thus reduce the water circulation in the cage. Application of copper oxide paints may be able to solve that problem. A field experiment with Completely Randomizes Design was applied with 9 treatments: paint without biocide; paints contained: 5% Copper Oxide; 10% Copper Oxide; 1% Chlorothalonil; 1% Chlorothaloni + 5% Copper Oxide; 1% Chlorothaloni + 10% Copper Oxide; 1% Zinc Omadine; 1% Zinc Omadine + 5% Copper Oxide; 1% Zinc Omadine + 10% Copper Oxide, each treatment was replicated 3 times. The research was done on July – September 2007 at Hanura Bay Lampung. Data of the abundance and diversity of macrofouling were collected weekly. The results showed that the application of copper oxide paints affected the macrofouling attachment significantly (P < 0, 01). The best result was antifouling paints contained Copper Oxide, and combination between Copper Oxide with Chlorothalonil and Zink Omadine. However, from the economical point of view, paint with 5% Copper Oxide could be suggested for preventing macrofouling attachment on the marine net cage.

Coral reefs, mangroves and birds are becoming the major attraction of tourism in three islands - Gili Meno, Gili Air and Gili Trawangan (Gili Matra) - Lombok, Indonesia. Since the launching as a conservation area in 1993, tourism in Gili Matra has grown rapidly. On the other hand, the ecosystem continues to be degraded. Sooner or later, the ecosystem degradation will affect tourism and economic sustainability of the community in Gili Matra. The purposes of this study were to identify the stakeholders, and to map the ecosystem management problems in Gili Matra, to provide the basis for policy making in the future. The research method was depth interviews and focus group discussion (FGD). Identification of stakeholders was conducted using stakeholder analysis, while mapping of ecosystem management problems was carried out by participatory mapping. The stakeholders, who manage the ecosystem as tourism assets in Gili Matra, are: government, community and businessmen. The fishermen, tourists and businessmen are the primary stakeholders, meaning they have a high interest and the greatest influence on ecosystem management. Destructive behavior of stakeholders, especially the main stakeholders has led to the degradation of the ecosystem in Gili Matra, so it is important to nurture these stakeholders, to sustain tourism and economic viability of the community in Gili Matra.

Tuberculosis (TB) is caused by Mycobacterium tuberculosis. Although TB is a curable disease, it continues to
be one of the most important infectious causes of death worldwide. Indonesia ranks 3rd on the list of TB high
burden countries in the world with 86,000 cases deaths and the Multi Drug Resistant Tuberculosis (MDR TB)
estimated cases in Indonesia is 10,000. This research was aimed to isolate and characterize of soft coral
Sinularia sp.-associated bacteria having antibacterial activity against Tuberculosis bacteria. There were
109 isolates collected from Sinularia sp. Two isolates from Sinularia sp.-associated bacteria, SC4TGZ3 and
SC4TGZ4 were successfully screened for antibacterial against Tuberculosis bacteria. SC4TGZ3 was found to
inhibit the growth of MDR TB strain HE, MDR TB strain SR and H37Rv. Whereas, SC4TGZ4 was found to
inhibit the growth of MDR TB strain HE. Based on PCR amplification 16S rDNA softcoral bacateria were
identified as follows: SC4TGZ3 was closely related to Pseudovibrio sp. and SC4TGZ4 was closely related to
Alpha proteobacterium sp.

TOURISM AND CONSERVATION MANAGEMENT OPTIONS FOR KARIMUNJAWA MARINE NATIONAL PARK (Case Study and Reviews)
Purwanti, Frida
Tourism is a nature-based industry that will have impacts on the environment. In order to achieve successful and sustainable tourism, tourism development and conservation of natural resources have to go hand in hand. This will be only attained through an environmental strategic tourism planning approach.
Karimunjawa islands as one of the largest marine protected areas in Indonesia, provide a wide range of opportunities for research and environmental education as well as for tourism and recreation. In 1995, the Central Java Government conducted a tourism development study, but the study failed to assess current tourist market. This study intent to analyse the existing tourist market and to offer management guidelines.
The study was conducted using qualitative methods to analyse the existing tourism market and its’ development plan by reviewing and examining the primary and secondary sources. The study revealed that local residents are not fully involved in the development of the tourism plan. It is considered that, at least initially, tourism in the Karimunjawa Islands should be developed on a selective and small-scale base. It is recommended that a development manual, guidelines and policies be prepared in support of the tourism development plan. Public education program and involvement of the local community should be encouraged to support the tourism plan. The proposed management guidelines cover three issues : the environmental impact of tourism development; the appropriate institutional and legal framework to regulate and monitor tourism development, especially on the islands; and the extent of local community participation

In this study we examined marine bacteria associated with different corals (Porites lutea, Galaxea fascicularis, Acropora sp. and Pavona sp.) collected from vicinity of Panjang island, Jepara, North Java Sea, Indonesia for their antimicrobial activities against the bacteria Echerichia coli, Bacillus subtilis, Staphylococcus lentus and the yeast Candida glabrata. A total of 13 bacterial isolates belonged to the members of Bacillus, Vibrio, Micrococcus, Pseudoalteromonas, Arthrobacter and Pseudovibrio were found to inhibit the growth of at least one test strain. Further examinations among the biologically active strains by using PCR with specific primers of non-ribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) resulted in the presence of NRPS gene fragments in the 2 members of Bacillus and Micrococcus and PKS gene fragments in the 2 members of Bacillus and Vibrio. Following cloning and sequencing of the PCR products, the fragments from Bacillus BM1.5 and Micrococcus BJB showed sequence identity with peptide synthetase genes of Bacillus subtilis (61 %) and Actinoplanes teichomyceticus (62.4%). On the other hand, PKS-amplifying strains Bacillus BJ.7 and Vibrio MJ.5 showed closest sequence identity with polyketide synthase genes of Bacillus subtilis (73%) and Anabaena sp 90 (62%), respectively.

PRELIMINARY STUDY ON POTENCY OF COPROSTANOL AND COLIFORM BACTERIA IN SEMARANG COASTAL AREA
Bachtiar, Tonny
Coprostanol, coliform, coastal, pollution, sewage
Fecal coliform bacteria have been widely used as a biological indicator of sewage (domestic waste) pollution. However, as a biological indicator in urban coastal waters, it has disadvantage, in particular because of increased volume of industrial wastes that are toxic and heated, increase of salinity, and low dissolved oxygen. These conditions may affect the growth rate of most bacteria, including fecal coliform bacteria that becomes under representative in sewage pollution in urban coastal waters. It is necessary to find alternative indicator that can be used to better understand the sewage pollution in urban coastal waters. Many researchers have proposed coprostanol as a chemical indicator of sewage pollution. To understand the existence of coprostanol and coliform bacteria, a preliminary study has been done on water and sediment samples from the river, river mouth, and seawater of Banjir Kanal Timur Semarang coastal waters. The results showed that coprostanol could be detected in sediment from all sites, on the other hand coliform bacteria decreased with the increase of salinity, and were not detected in the seawater.

giant clams, zooxanthellae, energy, CZAR, CZAG
Zooxanthellae are symbiotic dinoflagellate algae which live in association with marine invertebratesincluding giant clams. These algae are capable of translocating part of their photosynthetic products tothe host. This translocation is one of the nutrition sources of the host. The present study aims tocalculate the contribution of zooxanthellae on the energy requirements of adult giant clam (Tridacnamaxima) during their respiration and growth processes. The result showed that zooxanthellae arecapable of contributing 260.67% and 452.54% energy required by giant clams for respiration andgrowth during summer and 171.51% and 273.51 % during winter, respectively. It suggests that all theenergy required for these two processes can be supplied by zooxanthellae.

THE PERFORMANCE OF EARLY-AGE CONCRETE WITH SEAWATER CURING

Concrete, early-age, maturity, seawater, curing, compressive strength
It is well known that concrete has been implemented for marine structures. Marine environment causes physical and chemical deterioration of concrete structures, thus, there is no doubt that the durability takes an important role in concrete performance. Learning about the performance of early-age concrete is to study the maturity of concrete, which is a key of concrete durability where “Maturity Concept” attempts to predict the development of concrete properties as a function of time and temperature of curing and becomes an excellent indicator of in-place strength development and quality from fresh to hardened concrete. It is a hypothesis for this research that the compressive strength of early-age concrete cured by seawater is higher than the one cured by plain water.
This research was conducted by using two methods, experimental method and analytical method. The experimental method investigated the compressive strength of concrete cylinders, with 7 days and 14 days seawater curing and plain water curing. Concrete compressive strength design, f’c, is 22.5 MPa, and varies with water-cement ratio: 0.4, 0.5, and 0.6. After 7 days and 14 days of curing, the concrete cylinders were tested by compressive testing machine.
The experimental results of this research showed that the compressive strength of 7 days and 14 days concrete specimens with seawater curing is higher than those cured by plain-water, about 2.56-5.25% for 7 days old specimens and 3.39-11.87% for 14 days old specimens. The result also showed that the lower water-cement ratio, the higher concrete compressive strength would be. The analytical calculation also gave higher compressive strength to specimens cured by seawater, about 0.06-0.39% for 7 days old specimens and 0.11-0.33% for 14 days old specimens. The higher strength compressive of concrete specimens with seawater curing is provided by the existence of calcium chloride in seawater and by high temperature of seawater. The analytical result of the “Maturity Concept” has given a good performance in predicting the compressive strength of concrete very well veryfying the experimental results. The hypothesis of this research is proven, that both experimentally and analytically, the compressive strength of 7 days and 14 days old concrete specimens cured by seawater are higher than those cured by plain water.

Our previous study found that KLU 11.16, isolated from shrimp waste secreted chitinolytic enzymes. The crude enzyme was interesting since their chitooligosccharide was able to inhibit some pathogenic bacteria. In this study we report a purification and characterization of the chitosanase enzyme produced and the identification of the KLU 11.16. Purification of the enzyme was done two steps by ion exchange chromatography followed by gel filtration. Two out of 4 peaks from Gel Filtration step, i.e. fraction 16 and 33 were capable of hydrolyzing 100% deacetylated chitosan, indicating that both fractions contained chitosanase enzyme. The enzyme from fraction 16 had approximate molecular weight of 98.3 kDa. The enzyme worked optimally at temperature of 300C, and pH 6. Addition of Ca2+, Fe2+, K+, Na+ ions in the form of Cl2 salt and detergent Triton X-100 increased the enzyme activity, while Co2+, Mn2+ and Zn2+ ions in the same concentration decreased the enzyme acitivity. Addition of EDTA and SDS significantly decreased the enzyme activity. Molecular based identification revealed that KLU 11.16 was 99% similar to Aeromonas media.

As part of a pilot scale project on drug discovery from local marine organisms, 19 intertidal marine organisms from Singapore waters were collected and screened for the presence of biologically-active natural products. These marine organisms were collected due to the ease of procurement and their relative abundance. The organic extracts of these organisms were prepared and screened in the brine shrimp lethality (BSL), the cytotoxicity (MCF-7 and MOLT-4 cell lines), and the quorum sensing inhibition (QSI) assays. Over 60% of the extracts gave significant biological activities in the BSL and the cytotoxicity (MOLT-4) assays when tested at 1000 ppm. Three sponge extracts showed moderate antibacterial activity while a fraction obtained from the gross fractionation of the extract of the marine cyanobacterium, Lyngbya majuscula (PH2), exhibited anti quorum sensing activity in the QSI assay. Lyngbya majuscula (PH2) also exhibited exceptional biological properties in the toxicity assays and its extract underwent further fractionation. The 1H-NMR spectra of the bioactive chromatographic fractions derived from the microalgal extract indicated the presence of unique lipopeptides. Data from this study provided rationale to initiate marine natural products research for drug discovery in Singapore.

Tiger shrimp ; sargassum ; gracilaria ; integrated model.
Due to deterioration of shrimp farming environment, it is necessary to develop the technique of shrimp culture that environmentally friendly and sustainable. One of important technique to fulfill the need is integrated model with seaweeds. We investigated two different integrated model using different seaweeds species, Sargassum plagyophyllum and Gracilaria verrucosa. These two species seaweeds were cultured in tiger shrimp pond at density of 2 kg/m3. Density of tiger shrimp was 50 juvenile /m3. These experiments were conducted in 28 days. The shrimp productivity was evaluated from the rate of shrimp survival, final individual size, growth and biomass production. Seaweeds biomass production was also evaluated. Collected data was analyzed using one way ANOVA, continued by LSD test. Results indicated that the presence of both seaweeds tend to increase shrimp productivity, it was indicated by higher survival, individual size, growth rate and shrimp biomass production. The role of Gracilaria in increasing shrimp productivity was higher compared to Sargassum. It is recommended to use Gracilaria in integrated model with tiger shrimp.

calcium, potassium, fertilizer, sodium-toxicity
The research was carried out in April to July 1996 in the coastal area of Semarang in order to evaluate the effect of calcium and potassium fertilizer to plant growth and production of setaria grass and to observe sodium toxicity on the grass.
The experiment was arranged in two factor split-plot design with three replication. The main factor was the application of CaCO3 which was divided into three levels : 0, 4 and 8 ton CaCO3/ha and the sub factor was the application of KCl which was divided into three levels: 0, 40 and 80 kg K2o/ha.
Eight parameters were observed in this experiment : Total Dissolved Salts (TDS), Soil Electrical Conductivity (ECe), level of death plant, plant height, leaves numbers, fresh yield, dry yield and protein content.
The result show that the application of CaCO3 and KCl created inverse effect to Total Dissolve Salts (TDS) and Soil Electrical Conductivity (ECe). On one hand, CaCO3 decrease TDS and ECe and on the other hand. KCl increase TDS and ECe. There were interactions between CaCO3 and Kcl in influencing TDS and ECe. However, CaCO3 and KCl brought about similar effect to plant performance. Both CaCO3 and KCl decreased the level of died plant and increased plant height, leaves number, fresh yield, dry yield an protein content of setaria grass. CaCO3 and KCl did not interact each other in increasing plant performance.
The application of CaCO3 increased plant height significantly at week 3, week 4 and week 5, and increased dry yield and protein content significantly, but not increase fresh yield significantly.
The application of KCl increased dry yield and protein content significantly, but did not increased plant height, leaves number and fresh significantly.

It is also clear that no one management strategy will ensure that Indonesia’s significant coral reef and other marine are conserved and used in sustainable fashion. Rather, a judicious blend of the use of economic instruments and concepts, regulation, education, and “site-hardening” (e.g. by use mooring) is required to ensure that marine tourism is sustainable.

DIET DEVELOPMENT FOR MUD CRAB (Scylla serrata) AQUACULTURE USING LOCAL MATERIAL AVAILABLE IN CENTRAL JAVA
Hutabarat, Johannes
local protein materials, experimental diet, growth, food utilization and protein efficiency
Phase I study (1996/1997) indicated that the local protein materials at relatively low cost were found abundance in Central Java throught the year. Their nutritional levels i.e. protein content, amino acids profile and availability are suitable to be used for mud-crab feed development. It is therefore the selected protein materials such as : soybean, mysidaceae, trash fish and saga, are then subjected to the formulation of experimental diet for mud crab on-growing culture (Phase II study 1997/1998)
The aims of study are to determine the nutritional performance of experimental diets (novel diets) for mud-crab scylla growth, food utilization and protein efficiency during the feeding trial. The study has been conducted in a 12 bamboo-cages of 1.0 x 0.5 x 0.70 m immersed in BW ponds at CZEL “Prof. Gatot Rahardjo J.S – UNDIP”, Jepara and the stocking density of wild mud-crab (50-60 gram) was 1 pieces /box (0.2 x 0.2 m). Experimental diet (pellet formed) consists of four treatments i.e. diet A (25% dietary protein level), diet B (30%), diet C (35%) and diet D (40%).
The growth and nutritional parameters observed as response to the experimental diets tested are : Individual growth and growth increment, Specific Growth Rate (SGR), FCR, NOU amd PER. The completely Randomize Design was adopted in this study and then followed by Duncans’s New Multiple Range Test in order to determine the difference among the treatments.
The results derived from this study indicated that diet C (dietary protein level of 30%) appeared to be the best diet wheather for the growth (W and SGR0 or nutritional performance
(FCR, PER, and NPU) and followed by diet B, D and A. Meanwhile, during the course of feeding trial water quality of experimental media remain in good condition to support ud-crab growth.

CORAL REEF MANAGEMENT IN TAKA BONERATE MARINE NATIONAL PARK, SOUTH SULAWESI (A CASE STUDY FOR THE ALTERNATIVE TO DESTRUCTIVE FISHING PRACTICES ON CORN REEFS)
upriharyono, S
Coral reefs management, Destructive Fishing
The coral reef is the most productive marine ecosystem in coastal waters. The primary productivity may reach up to more than 10 kg C/m2/year. This resulted in a high number of fisheries production, such as fishes, shrimps, lobster, mollusc (shellfish), turtle, and others. Unfortunately, this condition has already suffered from non-sustainable human use including destructive fishing practices (bombing and cyanide), coral mining, over fishing, settlement pollution and uncontrolled tourism development. These affected the production of those fisheries resources in coral reefs. In order to manage those resources, such alternative to destructive use need to be studied.
This paper reports alternatives to destructive fishing practices on coral reefs. The study had been carried out at Taka Bonerate Marine National Park, the District of Selayar, South Sulawesi province, for about 3 weeks, 7-26 November 2000. Survey method was used during the study. The data were collected using Participatory Rapid Appraisal (PRA)’s method, with members of fisher group as the participants.
Three kinds of reef fish groups are identified at the Taka Bonerate Islands waters, i.e. major group, target group, and indicator group. These include ornamental and consumption fishes. These were caught with several fishing gears, while some of them are identified as destructive fishing practices, e.g. bomb, cyanide fishing. However, some of them can be recommended as sustainable fishing technologies, i.e. (1) pancing cumi-cumi, (2) pancing tonda, and (3) samba/kulambi.

A basic investigation on the removal of Mg(II) ion from aqueous solution by chitosan beads was conducted in a batch adsorption system. The influence of different experimental parameters; pH, agitation period and different concentration of Mg(II) ion was evaluated. A pH 7.0 was found to be an optimum pH for Mg(II) adsorption onto chitosan powder and chitosan beads. The Langmuir and Freundlich adsorption isotherm models were applied to describe the isotherms and isotherm constants for the adsorption of Mg(II) onto chitosan powder and chitosan beads. Results indicated that Mg(II) uptake could be described by the Langmuir adsorption model. The maximum adsorption capacities of Mg(II) ion onto chitosan powder and chitosan beads were 7.20 and 17.39 mol gâ^’1, respectively. The rate of adsorption Mg(II) on chitosan powder and chitosan beads were 16.0.10-4 min-1 and 48.00 . 10-4 min-1, respectively.

THE PROBLEMS OF COASTAL AND MARINE RESOURCES MANAGEMENT IN INDONESIA
., Supriharyono
J Coastal and Marine Resources Management
It is a well known fact that parts of the coastal marine ecosystem, such as estuaries, mangrove, sea-weed beds, and coral reefs, are very productive . The primary production may go up to 10,000 g C/m2{vear in these systems. It t`s very high compared with the primary production in open seas that is only 50-100 g C/m2/year. As a result the rate of the secondary production, such as fish, and other marine faunas, which live in these system, are also high. Anthropogenic activities carried out in order to use the resources in coastal areas, such as destructive fishing practices, coral mining, mangrove cutting, may ayiectfish Hncluding other marine faunas) production. Considering the destructive nature of some human activities in the coastal areas, the Indonesian government has established several laws and regulations for marine environmental protection. These included the establishment of 37 marine conservation areas which cover an area of about 2,800,000 Ha. It is expected that these areas will be expanded to 30,000,000 Ha by the year 2000, but there is no assurance whether this expansion can be reached or not. In the meantime a strategt to [ind alternatives to destructive practices in coastal and marine ecosystems is being prepared.

Chitosan was widely known as natural food preservative such as noodle, meat ball, soy-tofu, wide variety of
fresh vegetables, fruits, meat and fish products, etc. Chitosan is a non-toxic substances, has no side effect as
human food and was made from the shell of shrimps (Penaeidae), or swimming crabs (Portunus pelagicus).
Chitosan is primarily a polysacharids, with β-1,4-2 amino-2-deoxy- β- D-glucopyranose. The biopolymer
has various noble functional characters such as anti-moth, anti-bacterial, coagulating agent for suspension,
or heavy metals. This substance had been examined in the Lab of Natural Product, Diponegoro University
and give a significant effect as bacteriostatic and bactericides for pathogenic bacteria such as Salmonela.sp;
Pseudomonas, E.coli, B.subtilis, S.aureus, P.aeruginosa. In the study, liquid chitosan (200 ppm) was used as
anti- harmful/ pathogenic bacteria in the brackish water pond so that can eliminate and control the bacterial
or virus outbreak which so far is the main problems in the fish and shrimp culture activities. The use of
chitosan in the brackish water ponds was carried out at a semi-traditional ponds at Mangkang Kulon north
Semarang coastal area. The experiment had significantly decrease the suspended solid or increase water
transparency, and the organic content ( by 5 %) of the bottom susbtrate. Increase the abundance of
important macro-benthic organism such as Polychaeta (7-fold) as important natural feed for the cultured fish
and shrimp as well as increase the diversity index of total macro-benthic organism. Decrease the growth of
disease vector benthic organism such as Cherithidae (Gastropods) by 24.5% . With the application of
chitosan had significantly prevent the outbreak of fish and shrimp disease and increase up to 80 % the
survival rate of Vanamae, as well as tiger shrimp Penaeus monodon, and polkadot grouper (Cromileptes,sp)

Benthic diatoms; primary productivity ; mangrove
A study to determine biodiversity related to ecological function of secondary mangrove forests at central Java had been carried out in three different locations viz. Rembang, Demak and Pemalang coasts. Location of sampling was selected systematically in three levels of inundation within both lower and higher densities of mangrove. Sediment samples were collected randomly with four replications. A lens tissue trapping method was applied to collect living benthic diatoms. Primary productivity was measured in-situ in the locations as production of carbon per unit area per unit time. It was determined by dissolved oxygen content measured by the bell jar method. Data were then analyzed using a biodiversity index (Shannon-Wiener index), ANOVA, regression and cluster multivariate analysis for b biodiversity. Totally, 86 benthic diatom species had been found and the benthic diatom community assemblage was dominated by Amphora coffeaeformis, Diploneis crabro, Diploneis smithi, Navicula elliptica, Pleurosigma sp., Stauropsis majuscula and Surirella gemma. Benthic diatom abundance was 8.6750 x 104 to 18.9626 x 104 cell/m2, where the highest was found in Demak and the lowest was in Pemalang. Abundance of the diatom does not always have significant relation (P > 0.05) to both inundation levels and mangrove density; however, this was more depended on location. The assemblage of benthic diatom community was more similar in Rembang and Pemalang compared to that in Demak, however the a biodiversity index tended to be higher in the lower mangrove density. The benthic micro-flora primary productivity was 120 to 342 mg C/m2/hour and had no significant relation (P > 0.05) to abundance of benthic diatom. It was revealed that the optimum density of mangrove to have the highest benthic micro-flora primary productivity was between 8000 to 10000 trees/ha.

THE APPLICATION OF GLYROXYL AS DECONTAMINATION AND DISINFECTION AGENT FOR THE PRESERVATION OF FISHERIES PRODUCT
Darmanto, Y.S.

fresh prawn, glyroxyl, decontamination and disinfection agent
Fisheries products are regarded as perishable food. Fresh prawn is one of the most valuable fisheries products and its demand increases especially in developed countries. Handling and preserving of fresh prawn has been investigated to keep the quality. Glyroxyl has been successfully used as decontamination agent in the fish sector in the Netherlands. Apart from its use as decontamination agent, glyroxyl has been proved to be an efficient disinfectant. Due to its safe character, it is allowed to put glyroxyl in foodstuff directly, provided that the prescribed concentration is respected.
This study is aimed to investigate the effect of different concentration of glyroxyl (0, 0.3 and 0.5%) on the preservation of fresh prawn. The sample used was white shrimp prawn (Penaeus monodon). The samples were soaked in glyroxyl solution with different concentrations. The analyses were conducted for organoleptic, Total Plate Count (TPC) and E. coli at 0 and 3 days storage at refrigerated temperature.
The results showed that the use of glyroxyl solution (0%, 0.3% and 0.5%) has no effect on the organoleptic parameters of the sample (appearance, color and flesh). However, after 3 days of storage the effect of glyroxcyl became apparent especially for 0 % glyroxcyl treatment. The number of E. coli showed that application of glyroxyl could prevent the growth of E. coli and reduce the number of E. coli in the samples. In addition the E. coli obtained was less than number < 3 / < 3 in all samples after 3 days storage. Increase in glyroxyl concentration resulted in the decrease of bacterial number (TPC) both for 0 and 3 days storage

VERTICAL EXISTENCE OF COPROSTANOL IN A SEDIMENT CORE FROM SEMARANG COASTAL WATERS, CENTRAL JAVA, INDONESIA
Bachtiar, Tonny
Coprostanol, core, domestic, indicator, sediment, waste.
Coprostanol has been proposed as an indicator of domestic (sewage) pollution by researchers because constraint of using coliform bacteria as the indicators of domestic pollution in the environment with high environmental stress, such as urban coastal waters. Increasing the volume of industrial wastes, toxic and heated, the changing of water salinity from low (freshwater) to high (sea water), and decreasing of dissolved oxygen (DO) in the waters, are the constrain factors of bacteria growth. How ever, all the researches have been done in the temperate (high latitude) regions. Information existence of coprostanol in tropical region, especially in Indonesia is still very poor. To understand the existence of coprostanol in the sediments, one core sediment sample (60 cm) was collected from Semarang coastal water adjacent to Banjir Kanal Timur which is the main drainage system of the East Semarang municipal district in Central Java by using a small gravity corer in July 2001. The core sediment sample was divided into 12 sections (5 cm each) for analyzing the concentration of coprostanol, grain size, and TOC. The result shows that coprostanol could be detected in all sample sections (vary from 1.06 to 2.94 mg/g). Coprostanol has significant positive correlation with TOC, but not significant with grain size. Coprostanol has very significant negative correlation with the depth of core. Based on the potency of sedimentation rate analysis on Banjir Kanal Timur Semarang coastal waters (0.35 cm/month), the 60 cm core sediment was predicted as a result of 14 –16 year sedimentation. All of these facts show that coprostanol has an excellent persistence in the sediment of tropical environment, and reflect that coprostanol has a potency as an alternative indicator of domestic waste pollution in urban tropical coastal waters.

LAND TENURE TRANSFORMATION IN A REMOTE ISLANDS: A case of a historical sociology prespective in Karimunjawa islands
Rochwulaningsih, Yety
transformation; land tenure; local residents; commodity
The interesting problem is the phenomenon of the transformation of land tenure of local residents to the outside residence massively. The research method used is a qualitative method by using data collection techniques of depth interviews, group interviews, participant observation, archival studies and documents and literature study. The results showed, that there has been a transformation of land tenure with the indicator of controlling the small islands in Karimunjawa Islands by outside residents. Of the 22 small islands with a total area of 358.9 ha of which are not inhabited by the population, remained 24 ha (6.69%) is controlled by local residents. The condition is caused by several factors, among others: (1) enactment Karimunjawa as a National Marine Park, and then as one of the leading tourism region of Central Java province, (2) the low level of education of local residents and the limited productive business opportunity in agricultural sector, (3) low levels of welfare and the weak bond of local residence to their land property. In this context the land then becomes a commodity more than the means of production, and a decline in social status of the local population, which is only switched on as a tenant or other livelihood as laborers or open a small business.

THE EFFECT OF ABRUPT CHANGES IN SALINITY ON THE SFG OF THE MUSSELS
Sunoko, Henna Rya A.
Scope For Growth (SFG), environmental toxicology
Mytilus edulis of over one year old were exposed to three different proportion of fresh and salt water for seven days. The objective of the study is to evaluate Scope For Growth (SFG), using the physiological responses of mussels as a potential monitor of the impact of environmental stresses. The feeding rates, respiration rates, food absorption efficiencies, and SFG of the mussels were measured following the seven day exposure period. Clearance rates relatively showed a small decrease with exposure to decreasing salinities, but it was not statistically significant. Absorption efficiencies of the mussels in the three groups were generally not different. Respiration rates among the three groups were not effected by, but changed consistently with increasing proportions of fresh water. The SFG among the three groups did not differ significantly by Anova, but the P value (0.069) is very close to the level considered significant (0.05). this study suggests that the decreasing salinity “stressed” the mussels.
The selected raw materials, generally contains 10 essential amino acids (Arginine, lysine, histidine, phenylalanine, leucine, isoleucine, methionine, valine, threonine, and trypthophane) and a long chain of EFA (n-3 HUFA) and (n-6 HUFA) which are required by mud crab for their growth. The selected local raw materials are therefore nutritionally suitable for mud crab feed development in Central Java.

Construction ; bottom wall; “jodang” trap; selective; babylon tiger snail
The objective of this research was to obtain net mesh bottom wall construction of “jodang” trap that selective to babylon tiger snails size, i.e. only shell length of l < 4.27 cm approximately could pass through. There were 3 designs shapes of bottom wall construction tested, i.e. rectangular shape of 2.4 ´ 2.8 (cm) and 2 diamond shapes with net mesh size of 5,6 cm and primary hanging ratio of E1 = 0.7 and 0.5. The results showed that rectangular shape bottom wall trap construction was better than those two other constructions. Only 6.78% of snails with l ³ 4.27 cm could escape the rectangular shape bottom wall trap construction. Whereas 41.90% and 17.46% of snail shells with l ³ 4.27 cm could escape from both the diamond mesh bottom wall trap construction. According to selectivity curve, the rectangular shape bottom wall trap construction could retained snails with shells length of l ³ 4.33 cm. The two others retained shells length of l ³ 4.14 cm and l ³ 4.60 cm.

Karimunjawa archipelago, marine national park, has been considered to be a relatively pristine area that
have more than 90 species of corals. This study was conducted to detect any concentrations heavy metal
levels in the tissues of eight coral species. Based on life-forms, selected coral species are classified as
massive (Porites lutea and Goniastrea retiformis), submassive (Galaxea fascicularis and Stylophora
pistillata), foliaceous (Pavona decussata and Montipora foliosa) and branching/ramosa (Acropora aspera
and Pocillopora damicornis). The concentration of heavy metals in the coral tissues were assessed using
Atomic Absorption Spectrophotometer (AAS) technique. The present experimental results demonstrated that
metal in coral tissues were no significant difference between sites. Concentration levels of five heavy metals
were found to be in the order of Pb>Zn>Cr>Cd>Cu. Relating heavy metal concentrations to life-form
corals, there were no significant differences of all the metals (except Pb), the highest concentration of Pb
were found in foliaceous type of corals. The high level of Pb in foliaceous coral life-form (Pavona decussata
and Montipora foliosa), indicating that these coral species are usefull as potential candidates of
biomonitoring material for this metal. However, the use of corals as biomonitors should be considered
carefully in biological and local environmental factors.

MARITIME BOUNDARY DELIMITATION THE INDONESIAN CASE *)
Sitepu, M.J.
Indonesia is an archipelagic country with two thirds of its territory represented water. The concept of an archipelagic state us an important one to Indonesia, and the marine sector has never been more important to the notion. This importance is reflected in the priority which marine issues have recived from the government, including the instalment of the National Marine Council in September 1996.
Maritime boundary issue often concern claims for marine resources. Maritime boundary delimitation is a fundamental strategy to enforce national sovereignty over marine and coastal areas.
For Indonesia, accurate marine boundary delimitation is of primary importance to definiting the nature and extent of the country’s marine resources. Maritime boundaries will be drawn on charts and given due publicity. The limit of the territorial sea, contiguous zone, EEZ, and continental self are measured from straight baselines connecting the outermost points of the outermost islands of Indonesia
This paper will detail the current status of Indonesia’s maritime boundary delimitation efforts and its future prospect.

THE GROWTH ANALYSIS OF Stichopus vastus (Echinodermata: Stichopodidae) IN KARIMUNJAWA WATERS
Sulardiono, Bambang
Prayitno, Slamet Budi
Hendrarto, Ign Boedi
Stichopus vastus ; growth ; mortality ; recruitment ; potential utilization
Stichopus vastus is one of sea cucumber resources utilize which has commercial economic value, locally known as “gametes”. Because this species is continuously exploited, while the nature of life has not been known, one of them especially its growth. Aspect of growth is an important parameter which is used as a basis for evaluating these resources, hence this resource is well managed and can be utilized in a sustainable manner. The study aims to: (1) estimates the growth characteristics mortality rate, recruitment and potential use of sea cucumber of S. vastus in Karimunjawa. The study is expected to give beneficial to the species of sea cucumber resource management strategy at Karimunjawa waters, Jepara. The analysis of the growth parameters of S. vastus obtained values of growth coeficient (K) of 0.55 year-1 and length infinity L ∞ value of 315.80 mm. Therefore the obtained values of K tend to be close to zero value, it indicates the nature of growth tends to slow and with a relatively long life. Life span of S. vastus is 5.41 years, which can achieve body lengths of 283.06 to 296.91 mm, and the monthly growth rate ranged from 9.0 to 12.37 mm. The results of the analysis of mortality showed that S. vastus has value of total mortality (Z) of 0.98, natural mortality (M) of 0.298, and catch mortality (F) of 0.682, with the rate of exploitation (E) of 0.6963. This suggests that the rate of exploitation is above the threshold standard set by the Government of 0.5 (BRKP, 2004). The analysis of the S. vastus the recruitment showed that the higest percentage recruit occurred in May-June is 17.16 - 18.33%. This is presumably due to a population increase of the spawning process in those months, although the value of the addition is not very significant. It is suggested the need for regulations regarding: (a) the catchment season which is based on the tendency of the reproductive patterns of S. vastus, in Karimujawa, (b) restrictions on the size of the catch, (c) catch quotas, (d) the methods that are environmentally friendly catch, (e) permits the ship / boat used to catch sea cucumbers business. To support the success of regulation, it is necessary to strengthen community institutions through the management of sea cucumber resource-based society, with the Co-management approach.

The increasing need to introduce and emphasis the analysis of SST and its sub-surface layers of deep
water temperature (both horizontal and vertical) profile to analyze some oceanographic phenomena
such as up-welling process and its relationship to its seasonal variability and spatial distribution was
inevitable. Especially to avoid the misleading interpretation of using only sea surface temperature data
for deep water fish biomass distribution analysis, etc. Field SST data of July – August 1997 was
measured by CTD (Conductivity-Temperature-Depth) sensors on board of RV. BARUNA JAYA IV with
accuracy of 0.01 °C. Field SST data of 2002 and 2007 was derived from TRITON Buoy data base with
permission of Jamstec-Japan. All field and TRITON buoy SST data were processed into a spatial SST
layer using Kriging method with Er_Mapper (Licensed user) software, and overlaid on the bathymetric
layer. Average daily SST east monsoon 1997 (El Nino event) was 28.46°C, where as presumably La
Nina event 2002 : the average daily SST was 29.75°C and for 2007 was : 29.83°C indicates a higher SST than both 1997 and 2002. Average daily SST of west monsoon 2007 was 29.69°C. Daily SST of 2007 east monsoon was about 0.08 - 0.5°C higher than the same season of 2002 (TRITON Buoy data).
The paper analyze and revealed the fate / occurrence of up welling zone in adjacent of Halmahera islands as well as the Hot Event (HE) phenomena through the analysis based on multi-layer and subsurface horizontal of both horizontal and vertical temperature of the field measurement 1997 and 2002 and 2007 TRITON data. Spatial multi-depth-layer approach had been developed in the paper is important for the analysis of deep water large pelagic fishery such as tuna fishery and its spatial distribution pattern.

THE PERFORMANCE OF BI-FILTER ON THE PRODUCTION AND DISEASE INCIDENCE OF PRAWN (PENAEUS MONODON FAB.)
Prayitno, Slamet Budi
Prawn, Production, Biological filler, and Disease incidence
It has been long known that the most potent factor that influences prawn production was unfavorable environment due to industrial, agriculture and habitat wastes as well as improper application of good husbandry management. This research was designed to study the effect of biological filter on the growth of tiger prawn, water qualilv, and disease incidence. 7`wo sets of experiments, namely field stddy and laboratory experiment were conducted . Field survey was carrted out to collect field data on actual husbandry practices, production, water and soil quality. Laboratory experiment was aimed at evaluating the efhctiveness of biologicalfilter and disease incidence. Juvenile prawn e (j 5 gr.) at a density of 15 animals/M2; 20 animals/M2, and 25 animals/M2 were used as experimental animals. The observed parameters were field productivity, growth, survival rate, water quolitv, bacterial counts, soil quality and disease incidence. Experiments were carried in 3 replicates. Field survey showed that prawn production decreased steephr at the third production cycle as low as 627.65 kg/Ha compared to the first cycle (1893. 28 kg/lla}. Most prawn were weak, and very vulnerable to diseases. Bacterial count was more than I0Jcfii/ml. Water quality rapidly declined as prawn grew especially during the second and third cycles. Laboratory experiment with biologicalfilter in contrast demonstrated better water quality and
healthier prawn,. although water quality declined slightly along with both the age and density. The growth rate was better than during field trials; among three treatments there were signdicant dyferences; the survival rate was best at density of I 5 animals/M2 but, the best estimated production
was reached by density of 20 animals/M2 producing 2645 kg/Ha/cycle without any problems for around 4 cycles. Disease incidence and parasites infestation was undetected in the tank during the experiment.

Ostracoda, TOC, CNS analysis, Jakarta Bay
A short sediment core from the inner part of Jakarta Bay, Indonesia, was quantitatively analysed for ostracods (minute Crustacea), total organic carbon (TOC) and total nitrogen (TN) contents, and the vertical distributions were recorded. A total of 53 ostracod species were obtained from 80 continuous core samples. The dominant species were Keijella carriei and Loxoconcha wrighti, which are common in areas with high TOC and TN contents. Based on an analysis of ostracod assemblages and carbon/nitrogen ratio, the study site began to be influenced by organic contamination from around 1950. Although the population of Jakarta City has increased rapidly since then, TOC and TN contents which were low, have gradually increased (0.7%–0.9% and 0.10%–0.12%, respectively), probably due to addition of nutrients from river sedimentation. The increased sedimentation rate after 1950 resulted in an increasing TOC ratio. The observed correlation between TOC and dominant species shows that Phlyctenophora orientalis may be a good indicator for monitoring increases in the narrow TOC content range of 0.7%–1.1%.

Population dynamics of mud crab Scylla serrata were studied in Lawele Bay. The objectives were to determine population size structure and population parameters. Samples were obtained monthly using gillnets and baited traps. Less than 70% of gillnet catches during flood tide consisted of adults. Subadults and juveniles were 28.0% and 4.5%, respectively. Similarly, during ebb tide consisted of 51.7%, 24.2% and 24.1%, respectively. It suggests that gillnets are not size selective gear. In contrast, baited traps only caught adults and subadults with percentage of 90.5% and 9.5%, respectively. The CW¥ and K of males were slightly higher than females namely 21.147 and 1.38 for males and 21.023 and 0.83 for females. The mortality estimates are as follows: natural mortality (M) male = 2.48 and fishing mortality (F) male = 1.2, while M female = 1.78 and F female = 0.75. The difference was due to CW¥, K and Z. The results show that S. serrata population is still under exploited.

Chorella sp., Zn Concentration.
Research on the use of Chorella sp. on reducing of Zn concentrations was conducted in order to know Zn concentration which is maximally absorbed by Chorella sp.
In the preliminary experiment, there was the range of Zn concentration that caused the highest population growth of Chorella sp. was 0.1 – 0.4 ppm. In the main experiment, it was divided into five concentrations and one control with three replications. Each of concentrations was treated on Chorella sp. culture with the first Zn concentration (0.0042 ppm) in the medium culture. Those concentrations were 0.05 ppm, 0.15 ppm, 0.35 ppm, 0.45 ppm. All of the concentrations were given on the day of 5. The density of cells which was used for each flask was 100,000 cells/ml. The fertilizers used for each flask were : ZA, Urea, TSP, FeCl3, EDTA.
The result showed that there was an interaction between the population growth of Chorella sp. and the reducing of Zn concentration. The highest population growth of Chorella sp. was found in the treatment of 0.15 ppm Zn concentration.

COORDINATION AMONG LOCAL AGENCIES IN DECENTRALISED FISHERIES EXTENSION: COMPARATIVE PERCEPTION OF EXTENSION OFFICERS IN JAVA, INDONESIA
Waridin, ,
coordination, local agencies, fisheries extension, officers, and perception
This study is intended to describe the conditions of coordination among local agencies involved in the implementation of decentralisation policy in fisheries extension in Java, Indonesia. In addition, this study is also aimed at assessing the effectiveness of the policy implementation, and determines its relationship to coordination among local agencies involved.
Population of this study comprised all fisheries extension officers attached with Rural Extension Centres (RECs). A multi-stage random sampling method was utilised for selecting the subjects for the study. A total of 50 officers at 10 districts in three provinces were covered in this study. Data were collected during January to March 1998 by using interview and self-administered techniques. Descriptive statistics and correlation analyses were used in the study.
The majority of officers confirmed that the RECs were not coordinated with related agencies involved in implementation of the policy. This indicates that policy implementation is not effectively done. Coordination among agencies involved was found to correlate highly to the effectiveness of policy implementation. Intensity of coordination among agencies involved in the policy implementation needs to be improved. A clearer directive for functions, responsibilities and relationships among agencies involved might help in strengthening the current coordination functions.

Susilowati, Indah
Commitment, behaviour, community, fishers, Demak, discriminant.
The commitment of fishers towards their community development is investigated in this study. Several statistical tools such as discriminant analysis, cross-tabulation and compare means with independent t-test have been employed to analyze the data which were collected from 56 samples in the study area of Wedung and Moro Demak, Demak Regency. The results showed that the commitment behaviour of fishers might be guided by several variables such as Age, Sex, Educ, Exper, Inc, Stay. In order to improve the commitment levels of respondents, thus, magnitude of the observed variables in the model could be explored further. Lastly, the model of fishers’ commitment with discriminant analysis performes fairly good with the right prediction of the original grouped cases is correctly classified for about 62.5%.

GROWTH DETERMINATION OF TROPICAL LIMPET Cellana testudinaria (Linnaeus, 1758) LIVING ON THE ROCKY SHORE OF OHOIWAIT, SOUTHEAST MOLUCCAS, INDONESIA
Khow, Abraham S
Shell-length frequency distributions, Growth determination, Cellana testudinaria.
Monthly shell-length frequency distributions were used to analyse the size and age structure of the limpet population inhabiting the rocky shore of Ohoiwait, Southeast Moluccas. The lengths of the collected specimens ranged from 8.0 to 31.8 mm. The analysis of the successive frequency distributions suggested that the population consisted of 4 to 5 distinct age groups (cohorts) at any given time, and that two new cohorts recruited during the one-year investigation period. An analysis to determine growth pattern using FiSAT software showed that the longevity of C. testudinaria extended up to 2 years. The values of von Bertalanffy growth parameters (L¥, K and t0), estimated from size-frequency distributions, were 33.1 mm, 1.4 yr-1, and 0.09, respectively. The highest growth increments were 25% and 18% of the asymptotic length during the first 3 and 6 months, respectively. The effects of environmental variables on the growth rates showed important seasonal variations, with the highest increment of 2.6 mm/month during dry season. Here, growth parameter of C. testudinaria limpet shows the same value as other tropical limpets and depends on environmental variables.

The increasing of energy demand for public transport and a rise of oil prices lead to intense of using green fuel for sustainable future. Red-seaweed polysaccharide consists of carrageenan can be used for production of bio-etahanol, as it supplies monosacharides. In this study, the possibility of bioethanol production using red-seaweed as raw material was examined. The purpose of this research was to determine the method of bioethanol production using red-seaweed. Two separate anaerobic fermentation following acid hydrolysis, each by different type of yeast, bread yeast (Saccharomyces cereviceae) and tapai yeast were conducted in this study. Acid hydrolysis for 2 h using H2SO4 of 5% at 100 oC of 100 g seaweed gel derived from 25 g of red-seaweed showed an optimal hydrolysis process yielded sugar content of 15.8 mg mL-1. Tapai yeast was not suitable for fermentation of red-seaweed hydrolysate, while Saccharomyces cereviceae gave an alcohol content of fermentate of 4.6% after 5-6 days of fermentation at room temperature.

The study aims to investigating the morphometric and beaks relationships in the Bigfin reef squid, Sepioteuthis lessoniana Lesson 1830. It is shown that fin length and tentacle length linearly correlates with dorsal mantle length. Unlike fin-mantle relation which exhibits no sexual differences, tentacle tends to develop relatively more rapidly in female when mantle attains 70 mm. It is also evident that dorsal mantle length linearly correlates with lower hood length, with slope (b) and intercept (a) of 30.3 and 4.57, respectively. Logarithmic relationship is found between total body weight and lower hood length, with corresponding values of 2.84 and 0.611. Their application for coastal cephalopod biomass estimation from beaks is discussed.

In this study, bacterial strain KM221 was isolated from coral tissue in Menjangan Kecil Island, Karimunjawa, Indonesia. This strain is facultative anaerobic with MCPA (2-methyl-4-chlorophenoxy acetic acid) serving as the only known energy sources. Microscopy of isolate revealed that strain KM221 is gram-positive, catalase-positive, rod, spore-forming bacterium, motile, opaque, hair-like outgrowth and unpigmented colonies. The bacterium could not be identified on the basis of its carbon-source-utilization pattern, but a partial sequencing of the 16S rDNA analysis suggest that this strain is closely related to Bacillus iodinum.The ability to degrade MCPA herbicide was examined qualitatively in EMBA indicator medium. This bacterium grew exponentially with MCPA as the sole source of energy and carbon. The maximum growth rate (m max) and the saturated concentration on MCPA (Cs) were determined to be 0.8024 h-1 and 5.10 mg/l MCPA, respectively.

A total of 42 coral-associated bacteria were screened for their ability to produce secondary metabolites by using 16S rDNA-based approach. A specific oligonucleotides primer was used to amplify DNA non-ribosomal peptide synthetase (NRPS). Five strains were found to carry the NRPS gene and successfully inhibit the growth of other coral-associated and pathogenic bacteria. The phylogenetic characterization revealed that four strains belonged to currently known species Pseudoalteromonas luteoviolacea, Vibrio tubiashi, Vibrio carchiariae and Bacillus iodinum. On the other hand, one strain was apparently closely related with an unknown group of the gamma Proteobacteria, which was only recognized as uncultured clone 141H2.

The increasing use of herbicides in agriculture sectors have receives great attention with respect to their potential toxic effect on reef-building corals of Indonesia. One chlorinated compound, 2,4-dichloro phenoxy acetat (2,4-D), has widely been used as a herbicide and has become a substantial environment pollutant. Controlled tolerance experiment testing 2,4-D was performed on Porites sp. And Galaxea sp in Marine Station, Teluk Awur, Jepara. The effect 2,4-D on coral mortality and zooxanthellae expulsion were investigated. The result showed that short duration (48 h) laboratory test demonstrated dramatic effect on sloughing and death of coral. The median lethal concentration (LC50-48) was determined to be 23.20 ppm on Porites sp and 10.26 ppm on Galaxea sp. There were no significant differences between Porites sp and Galaxea sp on the toxic response of 2,4-D compounds.

EFFECT OF CHITIN AND CHITOSAN DERIVED FROM CRAB SHELL AND SHRIMP HEAD ON THE UNFROZEN WATER AND DENATURATION OF LIZARD FISH MYOFIBRILS DURING FROZEN STORAGE
Dharmanto, Y S
chitin, chitosan, myofibrils, unfrozen water, Ca-ATPase
The shrimp head and crab shell are rich in chitin and chitosan that can be used as the raw material in various industries. Chitin is composed of 2-acetamido-2-deoxy-D-glucose, whereas chitosan is composed primarily of glucosamine, 2-amino-2-deoxy-D-glucose. Chitin and chitosan can commercially be manufactured in the forms of powder, flake, chitinazed, nitrate chitin and 77-red chitin. Chitin and chitosan is of benefit to neutralize toxicity of polluted water, a pivotal role for strengthening the emulsion system, binding water and fat, advancing the loaf volume of bread, and for binding food drying, purification of apple, beer, wine extracts, etc.
To find out the effect of chitin and chitosan of shrimp head and crab shell on the unfrozen water and denaturation of lizard fish myofibrils during frozen storage, chitin and chitosan were added at certain ratios 0; 2.5 – 7.5 g / 100 g, with non chitin and chitosan treatments as control. Changes of unfrozen water in myofibrils during frozen storage were studied based on the relationship between water content and transition heat, which was determined by Differential Scanning Calorimeter (DSC), whereas Ca-ATPase activity was analyzed using formula introduced by Katoh et. al., (1977).
During frozen storage, chitin and chitosan treatments influenced the amount of unfrozen water and Ca-ATPase activity. Without chitin and chitosan the amount of unfrozen water in myofibrils decreased rapidly, whereas the decrease was moderate when myofibrils received chitin and chitosan. The change in Ca-ATPase activity exhibited a similar tendency to those of the unfrozen water indicating a close correlation between Ca-ATPase activity and amount of unfrozen water.

Seagrasses have been known to produce secondary metabolites that have important ecological roles, including preventing from pathogen infections and fouling organisms. A research aimed at screening the potential of bacterial symbionts of seagrass Enhalus sp. was performed. Bacterial symbionts including endophytes and epiphytes were isolated from the seagrass, and marine biofilm-forming bacteria were isolated from the fiber and wooden panels from the surrounding colonies. A total of 17 epiphyte and 6 endophyte isolates were obtained, however more biological activity was found among endophytes (100%) compared to epiphytes (47%) against biofilm-forming bacteria. In addition, bacterial endophytes inhibited more biofilm-forming bacteria than epiphytes. Interestingly more isolates were obtained from rough surfaces both from fiber and wooden panels than smoothe surfaces. Bacterial symbionts of seagrass Enhalus sp., in particular its endophytes show potential source as natural marine antifoulants.

Biofloc technology has added values in aquaculture management, both in water quality management and feeding management. As an optional feed, biofloc is capable to enhance growth due to high protein content. Bacteria, main component biofloc, can produce polyhydroxybutyrate (PHB) as reserve of energy and growth accelerator for fish.
The aim of the research were to study the effect of the different C:N and C:P ratio of media on the content of polyhydroxybutyrate in biofloc and to determine optimum media to produce high polyhydroxybutyrate content in biofloc. The experiment was arranged in factorial with completely randomized design in three replications. Treatments were C:N ratio of 15, 20, 25 and C:P ratio of 75, 100, and 125.
The result showed that C:N ratio and C:P ratio of media and their interaction affect the content of polyhydroxybutyrate in biofloc. C:N ratio of 20 and C:P ratio of 125 resulted in most polyhydroxybutyrate (29.25±7.376 mg g-1 biofloc dry weight). Ratio of C:N of media gave linier and quadratic responses and C:P ratio of media gave linier one. Optimum polyhydroxybutyrate production was obtained at C:N ratio of 20.9 and C:P ratio of 125 resulting in 29.66 mg g-1 biofloc dry weight (2,97%)

Carotenoids are pigments that can be used in various applications including cosmetics and precursor of
vitamins A. Carotenoids are mostly found in higher plant leaves, fruit, and bacteria. Marine bacteria
associated with seagrass Thalassia hemprichii collected from Menjangan Kecil Waters, Karimunjawa
Islands were screened to produce the pigment and has allowed the use of these microrganism as an
environmental friendly alternative source of new natural pigment. The isolation of bacterial symbionts on
Zobell 2216E medium from seagrass Thalassia hemprichii resulted in 20 isolates of which 8 bacterial
symbionts have produced pigments but only one bacterium positively synthesize carotenoids. Initial analysis
with atomic absorption spectrophotometric method revealed that the wave lengt of bacterial pigment were in
the range of 300-600 nm, which are categorized that within the group of carotenoid pigments. From the
results of molecular identification by 16S rDNA method, it was shown that bacterium TH8 was closely
related to Bacillus licheniformis with 98% homology value.

An open-system respirometer for measuring steady-state oxygen uptake rate of aquatic animals is described. The principle of the measurement was to calculate the difference between the oxygen concentrations of the water entering the respiratory chambers with that out from the respiratory chambers. This difference indicated the oxygen consumed by the animals for their respiration. The measuring system was tested to calculate the oxygen consumption related to dry body weight of scallop Pecten maximus L. collected from different populations. This correlation was expressed by allometric equation as: Y = aXb. The equation was then discussed with the finding of several authors.

Biodegradation, coliform, coprostanol, domestic, existence, rate.
Constraint of using bio-indicator (coliform bacteria) as an indicator of domestic (sewage) pollution in the environment with high environmental stress encourages the discovering of other alternate indicators. Coprostanol has been proposed as a chemical indicator of domestic waste pollution, but most research on were conducted in the temperate (high latitude) region. The persistence of coprostanol in tropical region, especially in Indonesia, is still very poor. It is very important to understand the persistence of coprostanol in the nature, as one of the requirements to propose coprostanol as an alternate indicator of domestic waste pollution. In order to better understand the natural biodegradation of coprostanol, experimental system on three environmental conditions (river, river mouth, and coastal waters) was conducted. In April 2004, samples of water and surface bottom sediments were collected from each environmental condition in duplicate. Before the samples were put into aerated and non-aerated aquaria, about 35-40 g of surface bottom sediments were taken to analyze the initial concentration (C0) of coprostanol. The sediments were subsequently sampled from each aquarium within a certain interval day to analyze the concentration of coprostanol (C10, C20, and C40). The results showed that aeration plays not an important role in natural biodegradation of coprostanol. In average, the highest rate of coprostanol biodegradation is 0.438 μg/g day-1 in non aerated coastal water environment, where as the lowest was found in the non aerated river mouth environment (0.021 μg/g day-1). Since coprostanol was degraded very slowly, and could be detected in the sediments of three environmental conditions, coprostanol has an excellent potency to be used as an alternate indicator of domestic wastes.

WILL CO-MANAGEMENT APPROACH BRING A GOOD PROSPECT FOR BABON RIVER MANAGEMENT IN SEMARANG, CENTRAL JAVA-INDONESIA?
Susilowati, Indah
Co-management, participation, Stakeholders, Babon River, Semarang, Indonesia
Semarang Municipality is passed by Babon river in the Eastern part. This river flows from Ungaran in Semarang Regency at the upper-stream and streams down to Java sea in Demak Regency.This river is utilised by various parties for multi-purposes. Thus, to manage Babon river and its watershed need coordination among the stakeholders. In this case, community as one of the competent stakeholders is considered as the most important role player who determine the success of sustainable river management.
Babon river passes Semarang City longer than Semarang and Demak regencies. It seems when the stakeholders of Semarang pay more attention to Babon river will harvest more benefits compared to its costs. It indeed needs sharing in responsibility and understanding among the stakeholders along the watershed of Babon river. Collaborations between G to G (such as Germany and Indonesia) and Local Government (LG) to LG are seriously needed to support the success of the river management. Nevertheless, many efforts have been made on it. As mentioned by Lilin (2000), the existing participation contributed by community and key-persons along the Babon watershed in Semarang City were relatively low. The preliminary survey indicated that introducing co-management approach among the stakeholders in managing Babon river will provide a good prospect in the future. Many evidences have shown the success of co-management approach in managing natural resources in the third world countries in Asia, Africa and the developed ones.
Babon river is a common resource, open-access to any parties and transboundary along three regions, thereby, need protocol concept to achieve the optimal management. What are the priority and how co-management should be implemented in Babon river are not easy questions but subject to further research.

The sustainability in the integrated human and nature systems or social–ecological systems(SES) of reef fishery needs attention, because the livelihood of many coastal communities is dependentupon it. Likewise, coral reef ecosystem is important marine resource as a source of biodiversity, aspawning aggregation for various reef fish and biota. However, coral reef ecosystem in South Sulawesihas been pressured by reef-related fishing activities, which include destructive practices of bomb andpoison fishing.This study assesses the condition of fishery sustainability in five selected small islands situated inTaka Bonerate Marine National Park and Spermonde Archipelago, South Sulawesi. Multi-criteriaanalysis (MCA) is used as a decision-making tool to analyze and evaluate multiple indicators under aparticipatory group decision-making environment (Mendoza and Prabhu 2004). Four variable criteriaof sustainability indicators are included, namely ecological-criterion indicators, economic-criterionindicators, social-criterion indicators, and institutional-criterion indicators. The result of theassessment is analyzed with the state of coral reef and the state of destructive fishery in the area.

Lemuru Fish (Sardinella longiceps) have high enough of protein contents (17,8-20%). However, lemuru fish also contains important fatty-acid, especially omega-3. Because of the contains of fatty acid was high (1-24%) and the texture is not compact, the fish become easily be broken and become spoiled. That was because of the activity of microbes or the autolysis on the post morterm. Because of that, the right and intensive handling is needed , it can be done with immediate process or with long-lasting storage. In this research, the pickling method that used was smoking with liquid smoke.
The purpose of this research is to find the optimum operation condition for liquid smoke process of fish lemuru to produce lemuru fish that its fatty-acid Omega-3 did not decomposed and the fish has unique taste.
The methods of this research was completely random design with concentration of liquid-smoke as the treatment and duration of liquid-smoke as the block. The fixed variables are the weight of fish, fish thickness, temperature, salt contained and duration of measurement. The non-fixed variable is concentration of smoked-liquid.
At the condition where the concentration was 6% , 25 minutes of the soaking time gave the best optimal condition which the score shown was EPA = 0.6066 g/100g ,DHA = 0.4033g/100g, TBA = 0.86 mg/kg, TVB = 4.432 mg N/100g, TMA = 5.47% mgN and the total of microorganism is 3.62 x 106 CFU.

INTRASEASONAL VARIATIONS OF NEAR-SURFACE ZONAL CURRENT OBSERVED IN THE SOUTH-EASTERN EQUATORIAL INDIAN OCEAN
Iskandar, Iskhaq
Equatorial Indian ocean; Kelvin wave; Wyrtki jet; zonal current
Dynamics of intraseasonal variability in the near-surface zonal currents in the southeastern equatorial Indian Ocean is examined through the analysis of the observed currents at 1.5S, 90E and sea surface height (SSH) as well as wind fields along the equator for the period of 23 October 2001 to 3 July 2007. The result demonstrates that the zonal current has energetic intraseasonal variations within the period band of 30–70 days. These oceanic intraseasonal variations are forced by the atmospheric intrasea-sonal disturbances from the west to the central Indian Ocean basin west of the mooring location. The coherence analysis indicates that these intraseasonal zonal currents are coherent with the intraseasonal SSH along the equatorial Indian Ocean. The coherence and lag-correlation analyses agree that these intraseasonal zonal currents are associated with eastward propagating waves with a phase speed falls in the first two vertical modes of baroclinic waves observed in the equatorial Indian Ocean.

COASTAL AND MARINE ECOSYTEMS MANAGEMENT STRATEGY IN INDONESIA
., Supriharyono
Coastal Management Strategy
Its is well known that estuaries , mangroves, seagrasses beds, and coral reefs are productive ecosystems in the coastal marine areas. The production may goes up to 3.000 g C/m2/year. It is very high compared with the production in open seas that only 50 – 100 g C/m2/year. The coastal water ecosystems are also known as good habitat for spawning, nursering, and feeding several species of fish. Therefore, the secondary productivity is also high in these ecosystems. Anthropogenic activities in order to used the resources in coastal areas, however, are often dangerous to the life of those ecosystems.
Considering to the anthropogenic activities, the Indonesian government have established several law and regulation for marine environmental protection. These included the establishment of 23 marine conserves areas which cover areas of about 2.800.000 Ha. These areas are expected will be expected will be expanded to 10.000.000 Ha by the end of 1995, and 30.000.000 Ha by the year of 2000.

EXPLORATION OF SKIPJACK FISHING GROUND THROUGH SEA SURFACE TEMPERATURE AND CATCHES COMPOSITION ANALYZES IN PALABUHANRATU BAY WATERS
Simbolon, Domu
Limbong, Mario
Sea surface temperature; skipjack; fishing ground; Palabuhanratu Bay
Fishing ground condition is usually affected by oceanographic parameters. One of the oceanographic parameter that had been used in forecasting the availability of pelagic species such as skipjack is sea surface temperature (SST). Skipjack fish is the main target for boat seine net fishery in Palabuhanratu Bay from June to October 2007. Information on skipjack fishing ground availability is very important in order to optimize fishing operation. The purposes of the study are: to determine the SST distribution, to analyze the catch composition of skipjack, to determine the relationship between SST and skipjack catch, and to forecast the skipjack fishing ground in Palabuhanratu Bay from August to October 2007. The research consist of two stages. The first stage was conducted in Palabuhanratu Bay waters in August-October 2007, using survey method, with ten samples of boat seine net (payang). The second stage conducted on December 2007 to collect the SST data, which downloaded from the internet. The range of SST in Palabuhanratu Bay waters ranged from 22oC - 29oC in August 2007, 21oC - 27oC in September 2007 and 20oC - 31oC in October 2007. The SST had no significant effect on catch volume of skipjack in Palabuhanratu Bay during August until October 2007, but gave effect to the size distribution. The big skipjack distributed at the wide range of SST, but the small skipjack distributed at the narrow range of SST. The potential fishing ground of skipjack in Palabuhanratu Bay during September 2007 was found at Teluk Ciletuh, Ujung Karangbentang, Cimaja, Teluk Cikepuh, Ujung Genteng, and Gedogan waters.

STRATEGIES FOR MANGROVE REHABILITATION IN AN ERODED COASTLINE OF SELANGOR, PENINSULAR MALAYSIA
Stanley, Oswin D

eroded coastline – rehabilitation – mangrove – hydrology
Continuous mangrove ecosystem degradation and coastal erosion is observed along the coastline of Sungai
Haji Dorani, (N 03038’36.6”; E 101000’37.3” to N 03038’37.9”; E 101000’34.0”) Selangor, Peninsular
Malaysia. Foreshore mangrove plantation challenges below mean sea level are in progress in this high
energy coast. There are interventions of gabion breakwaters and geo-textile tubes to alleviate the wave
velocity striking the shore. The area between the breakwaters and coastline is chosen for mangrove
plantation. The soil is fluid silt sludge with average clay, silt and sand proportion of 43.03 %, 351.8 % and
5.14 % respectively. The maximum height of the tide recorded onshore was 2.8 m and in the middle of the
plantation area the height of the water flooding is ±3.5 daily during tides. Number of plant species on the
SAUH concrete revetment is 43 with 12 mangrove species and on the fringe reference mangroves is 27 with
8 true mangrove species. This paper explains the method to identify the potential location for mangrove
rehabilitation, possibility of establishing mangroves on the seafront in the chosen area and conservation of
the existing strip with 14 mangrove species. Overall sediment accretion since May 2008 is ±0.0037cm per
annum which is considerably negligible. Opening out the earthen bunds along the coastline is the actual
solution for natural mangrove translocation and stabilization in this particular coastline, however, it is not
practically possible. Hence, we have studied an alternative strategy of rehabilitating mangroves at the
elevation of +0.5 m to 1m MSL along this shoreline and also in an engineered firm sediment filled zone. We
propose carrying out hydrological restoration in the natural habitats for survival and further natural
colonization of mangroves.

Toha, Budiyanto
diatom, epipelic, bioindicator, water quality
Biomonitoring methods for water quality, such as coli form content, diversity and evenness indices of macrobenthic invertebrates and plankton which are recently used, actually have some weaknesses. Escherichia coli only indicated pollution caused by faecal coli; macrobenthic invertebrates have not ability to live in all substratum, whereas the population of phytoplankton are affected by current as they are floating in the surface water. Therefore, the method which are more effective have to be developed. Epipelic diatoms have potential characteristics as bioindicator of water quality because the have ability to accumulate physic-chemical component of aquatic ecosystem and respond it immediately.
This research is conducted in order to find out a new alternative of biomonitoring method ( species indices of diatoms ) which are more significant, effective and efficient by determine water quality map absed on diatoms and determines the species which responsible to the grouping.
Sediments samples were taken from 7 rivers in the Northern Coast of Central Java (called Pantura): Karanggeneng-Rembang, Juana-Pati, Banjir Kanal Timur-Semarang, Banjir Kanal Barat-Semarang, Banger-Pekalongan, Pekalonghan-Pekalongan, and Gung-Tegal. Temperature, dissolved oxygen, salinity, pH and turbidity were measure in-situ. Analysis of water and sediment samples include total nitrogen, total phosphorus,silica, heavy metals of Cu, Cr, and Cd. Extraction, preparation and identification of diatoms followed Wetzel & Likens (1991) and Round (1993). The`data were then analysed using Primer package progamme version 4.0 which is produced by Plymouth Marine Laboratory, United Kingdom (Carr, 1997). The Multi Dimentional Scaling (MDS) ordination was done to make grouping and was followed by SIMPER analysis to determine responsible species (Clarke & Warwick, 1994).
Based on diatom community, 7 river Pantura could be divided into 3 groups: Group I, consisted of Gung and Pekalongan Rivers, Group II of Banjir Kanal Timur, Barat and Banger Rivers and Group III Karenggeneng and Juana Rivers. Synedra ulna was responsibled for those grouping and are therefore could be promoted as bioindicator of water quality in the Indonesian river. Research still should be developed, especially for diatoms in the bottom layer of sediment samples to reconstruct ecological condition in the past and to predict the condition in the future.

DIETARY PRACTICAL INGREDIENTS WITH EMPHASIS ON PROTEIN SOURCES FOR PENAEID SHRIMP
Sudaryono, Agung
Penaeid shrimp, protein, dietary
Studies on the utilization of dietary practical ingredients, in particular protein sources, by penaeid shrimp juveniles were reviewed in this paper. It has been proved by a number of researchers in shrimp nutrition that diets containing a mixture of two or more protein sources are better utilized by shrimp than those containing single protein sources. In general, evaluation of the nutritive value of a feed ingredient for growth is based on both the quantity and the quality of the protein in the ingredient. The amino acid composition and the relative proportions of other dietary nutrients are mostly relevant to the efficiency of protein assimilation by penaeids. Based on the essential amino acid index (EAAI) used to screen some potential protein sources for penaeid shrimp, there were found that fish meal, shrimp meal, squid meal and soybean meal were good dietary potential protein sources with EAAIs between 0.87-0.98.

shrimp aquaculture ponds, eutrophication, coastal pollution, Central Java
In order to determine the extent of eutrophication due to pollution of organic matter from brackishwater shrimp ponds, on the north coast of Central Java, chlorophyll a and nutrient concentration were measured in near shore waters. It was revealed that chlorophyll a content in the study area were considerably high, ranging between 83 and 332 µg/l. The evidence of eutrophication was also supported by the relatively high level of nutrient, in which nitrate levels ranged between 1.295 and 2.060 mg/l and phosphate ranged between 0.093 and 0.270 mg/l. The relationship of chlorophyll a and nitrate indicated negative of chlorophyll a and phosphate also indicated negative correlation with regression : P = - 0.2587 Chl a + 0.1945. This suggests that the increase in chlorophyll a is accompanied by a reduction of both nitrate and phosphate, which may be caused by luxurious consumption of nutrient by phytoplankton in the surface water.

The research aim was to study Chromium (Cr) content in the waters and in the crabs (Scylla serrata) in Brackishwater ponds around Babon River estuary of coastal areas Semarang, in Central Java. Systematical random sampling was used in this study. Analysis of Cr content in the water was compared to water quality criteria by Indonesian Ministry of Environmental. Analysis of Cr content in the tissue of crab was based on Manual Criteria by United States Food and Drug Administration (U.S. FDA). Bioconcentration Factor was used to analyse the accumulative of Chromium content. The results showed that Chromium content in the water was 0,078 ppm (dry season) and 0,065 ppm (rainy season), respectively. Chromium content in the tissue of mud crab (Scylla serrata) was 5,237 ppm (dry season) and 4,848 ppm (rainy season) and was under of maximum level recommended (12 ppm). The Bio Concentration Factor (BCF) of Cr content has low accumulative characteristic (<100).

NATURAL CORAL COLONIZATION OF A MARINA SEAWALL IN SINGAPORE
Ming, Chou Loke

Scleractinian diversity; seawall; Singapore; tropical marina
Marinas require extensive modification of a natural coast. The resulting modified habitat is known to support
changed biological communities but the ability of tropical marinas to function as a surrogate habitat for
scleractinian corals has not been well investigated. An assessment of scleractinian corals naturally
colonising a nine-year-old marina seawall in Singapore indicated 26 genera from 13 families, of which
Pectinia and Turbinaria were the most dominant. Most colonies measured 10 – 25 cm in diameter. Reefs of
adjacent islands provided the larval source while the marina’s environmental conditions favored larval
recruitment and growth. Specific larval settlement preferences as well as sediment rejection capabilities of
the two most common genera could have contributed to their dominance. The study showed that the seawall
of a marina can support scleractinian coral communities and with relevant management, can significantly
enhance marine biodiversity.

Diatom ; dynoflagellate; bacteria ; estuary; carbon content
Carbon content of diatom, dinoflagellates and bacteria were studied in order to estimate the living particulate organic carbon (LPOC) in an estuarine system. In the water column, diatoms were most abundant in spring than the other seasons. Dinoflagellates, cyanobacteria, and microzooplankton were present in all seasons, even low in cell numbers. The highest abundance of bacteria was at inner region of estuary and lowest at the mouth of Bekanbeusi River. The percentage of benthic diatom to total diatoms assemblages on sediment surface was higher than that in the water column. The POC in water column was composed of 13 – 24 % for diatoms and 0.6 – 1.6 % for dinoflagelate in carbon base throughout a year. The contribution of diatom carbon to total POC showed highest percentage in June (24 %) in the Akkeshi-ko estuary. In general, bacterial carbon was lower than that of diatoms carbon. On average, the contribution of bacterial carbon was 5-8 % to the total POC throughout a year.

Detergent Linear Alky]-benzene Sulfonate (LAS), Sea bass larvae, LCSD-96 hours; Chronic Effects; Growth; Survival Rate
Sea bass (Lates calcal&r Bloch), one of the economically important marine fish, is getting more important for marine-culture. This fish is categorized as a euryhaline species, i.e. with a wide salinity tolerance, range 32 — 35 ppt, and in the river, estuarine and mangrove areas with the salinity between 0 - 25 ppt. The adult of sea bass is spawn in marine waters while the larvae and juvenile are is spawn mostlv found in the estuarine. Estuarine water is known as a good nursery and feeding ground, however it is also knownias a pollutant trap. Therefore, the larvae of seabass and other euryhaline species are very susceptible to this condition.Suryizctant detergent Linear A lkyl—benzene SuU"onate (LAS} is a non—ionic so]? detergent, with a long straight carbon chain, has a powerful cleaning capability; it is toxic to aquatic organisms, and however it is biodegradable. Therefore, it is widelv used for cosmetic and household purposes. This research was done to find out the chronic effect (LCM-96 hours) and acute ejects of detergent LAS on the larvae of sea bass (Lates calcaliver Bloch}. A Bioassay method was applied to jind out the acute toxicity, and Probit Analyses is used to find out the LC 50-96 hours of detergent LAS on sea bass larvae. Randomized design was carried out to observe the chronic ejects on the growth and survival rate ofthe sea bass larvae. There were six treatments applied, i. e, : A (0% of LC ,,,-96 hours); B (5% of LCM-96 hours}; C (10% of LCM-96 hours); D (/5% of LC50-96 hours); E (20% of LCM-96 hours); F (25% ofLCm-96 hours).The results showed that the treatment of LCM-96 hours of detergent LAS on sea bass larvae, I. I8 mg/I, was considered as moderatelv high toxicity. The absolute biomass growth of sea bass larvae was not afected by sub·lethal concentrations of detergent ALS, however, chronic concentrations of detergent LAS tyfected the daily growth rate of sea bass larvae signyicantb¤ (o<0.0l). As a conclusion, the acute toxicity of LAS detergent on sea bass (Lates calcaliver Bloch} larvae was l. I 8 mg/l. The sub—lethal concentrations of detergent LAS on the sea bass larvae did not influence the biomass growth and survival rate but affected the daib¤ growth rate of sea bass larvae significantly. The sea bass larvae exposed to the sub lethal concentrations of LAS detergent hr 30 days resulted in the gill damage, i.e..· hypertrophy, hyperplasia, telengeastases and melanization of the gill. The congestion and vacuolar degeneration ofthe liver were also observed.

Helmi, M.
spatial modeling, coastal water, ecology
Coastal water ecology represents a significant gain with regard to regional and local economic, fisheries (including marine culture), tourism and other activities. Measuring their typical spatial distribution pattern, however, has proved challenging since the real coastal water parameters as a part of a whole ecosystem and their interactions has never been revealed so far.
A GPS guided sampling and in-situ measurement for the field data, digital and an image processing analysis were applied to insure that the simulated coastal water-ecology model was displayed with high levels of spatial, geodetic and real-data accuracy. The derived techniques could ultimately provide to coastal managers and decision makers with truthful ecologically and cost-effective means to assess the right zone for fisheries and other coastal water activities based on both temporal and spatial changes.

The concentrations of Cd, Cu, Pb, Zn, Ni and Fe were determined in the marine gastropod Nerita lineata collected on May 2005 from the intertidal zone of fourteen stations in Dumai, Indonesia (mean length 21.43 – 24.04 mm) and ten stations in Johor, Peninsular Malaysia (mean length 22.61 – 26.60 mm). The results of the present study showed that metal concentrations in the shell, operculum and soft tissue of N. lineata varied at different sampling stations. The mean concentrations of Cd, Cu, Pb, Zn, Ni and Fe in the samples collected from Dumai were 4.14; 5.90; 44.43; 3.74; 20.73; 24.91 μg/g in shell; 4.16; 7.31; 51.78; 17.63; 23.52; 30.60 μg/g in operculum and 0.71; 15.16; 9.34; 94.69; 5.08; 397.96 μg/g dry weight in the total soft tissue; whilst those collected from Johor were 4.18; 5.06; 59.84; 4.8122; 19.29; 31.60 μg/g in shell; 4.73; 6.51; 60.57; 19.48; 20.68; 34.92 μg/g in operculum and 1.24; 18.02; 19.75; 95.09; 5.57; 473.56 μg/g dry weight in the total soft tissue, respectively. Samples of N. lineata from both Dumai and Johor tend to show similar trend in metal accumulation in which the concentrations of Cd, Pb and Ni decreased in the order: operculum > shell > soft tissue whilst Cu, Zn and Fe in the order of soft tissue > operculum > shell. In general, samples from Johor accumulated higher heavy metal concentrations when compared to samples from Dumai, except for Cu and Ni in the shell and operculum, which exhibited vice versa situation. Higher concentrations of metals were recorded in samples collected from the stations close to the industrial and anthropogenic activities. However, most of the concentrations were still comparable to the previous reported studies from other geographical areas.

Avicennia marina ; salinity ; water storage tissue ; stunted growth ; thane creek
The mangrove Avicennia marina is a dominant mangrove along the anthropogenically stressed tropical Thane creek, west coast of India. Leaf anatomy of the mangrove along the Thane creek, was assessed in relation to stationwise and seasonwise variations in salinity. It was noticed that under the conditions of higher salinity, Avicennia marina showed increased thickness of hypodermal water storage tissue in the leaf (for conservation of water) and produced taller salt extruding glands at the lower epidermis to eliminate more salt; whereas, the thickness of the photosynthetic mesophyllic tissue significantly reduced. At lower salinity or with reduction in salinity in monsoon, contrary to above occurred. These changes probably explain the stunted growth of Avicennia marina in high salinity environment and its vigorous growth at lower salinity.

A study was conducted in South Sulawesi including Takaboberate Islands and adjacent areas from October 1994 to March 1995 to describe the cephalopod fauna in the area and to assess the status of their utilization. Six major observations and specimen collection were carried out around Pulau-pulau Selayar, Rajuni, Tinanja, Taka Lamungan, Tarupa and landing places in Ujung Pandang and Pare-pare. Most observations were made by means of snorkeling. Identification of specimens were carried out upon fresh specimens, which were then preserved in 4% formalin for 1-2 day depending on their size, prior to transporting for further laboratory observations and deposition. Fifteen species of cephalopods, representing 4 species of the family Loliginidae, 1 species of Enoploteuthidae, 7 species of Sepiidae, 1 species of Octopodidae, and 2 species of Nautilidae were identified. During the survey, spawns of 2 species of family Sepiidae were also collected, however there were no strong evidence of the occurrence of spawning ground for the species in the area, at least during the period of survey. The MSY for squid was estimated to be 1.840 ton per year, corresponding to an optimum effort of 4.800 bagam-prahu. Further increase intensity is possible, although a cautious management required, including continuous monitoring of the fishery and squid biology.

Sinularia sp., growth inhibition, crude extract
Marine biofouling has been recognized as a big problem faced by marine technology, and has caused huge economic losses to marine industries. Until recently, marine biofouling has been controlled by the use of metal-based coating which has become another problem because of their negative impacts on marine environments. Soft corals have been known to produce secondary metabolites, some of which may inhibit the fouling processes.
The objective of this research was to examine the antimicrobial properties of soft coral Sinularia sp against marine biofilm-forming bacteria
The results showed that the soft coral tissues of Sinularia sp. had the antibacterial potency. The crude extracts of Sinularia sp affected significantly on the growth of bacteria tested. The optimal concentration of crude extracts needed to inhibit the growth of bacteria was 150 µg/ml. There were no significantly different among bacteria isolated from fiber, wood and iron steel on diameter of inhibitory zone of the bacterial growth.
It is concluded thet the search of bioactive substances produced by soft corals is great possibility to find alternatives for metal-based coatings. Yet, a series of researchs must be undertaken in order to find the secondary metabolites which may be used as antifoulant.

THE POTENTIAL NEGATIVE IMPACT OF AIR LEAD POLLUTION ON CHILD DEVELOPMENT A PRELIMINARY STUDY IN TAMBAKLOROK, SEMARANG
Husni, Amin
lead-air, lead-blood, child development
A review about potential negative impacts of air lead pollution especially on child development, based on a result ofa cross sectional study conducted in Tambaklorok-Semarang, an area with a very high air lead pollution, is reported. Subjects in the study were mothers who have lived more than three years in the area and their infants. The `subjects' characteristics, including age, height, weight, lead blood concentration (Pb- blood), Hemoglobin (Hb}, and the infants' developmental score were measured. The air lead concentration was measured for comparing to the air lead concentration reported by a previous research.
Re-measurement ofthe Pb-air in August 1999 in Tambaklorok had a similar result with the Pb- air measured in August 1996 that was 100 times higher than that in a non·polluted Pb·air area. Statistical analysis showed that there was no signyicant correlation between the child Pb-blood and Matemal Pb-blood child ’s age, child ’s Hb, child ’s nutritional status that was calculated using Mass Body Index, and child development score, respectively. It seemed that child development was not influenced by the air lead exposure. The children were suffering fom anemia, but there was no signyicont correlation between the child Pb-blood and the child Hb.

DISTRIBUTION OF SEDIMENT, BENTHIC FORAMINIFERA AND MERCURY IN THE SOUTH YATSUSHIRO SEA, KYUSHU, JAPAN
Rifardi, R.
Bottom sediment, benthich forminifera, mercury
Bottom sediment samples were collected at 74 stations in the South Yatsushiro Sea, off the west coast of central Kyushu Island, Japan using gravity corer. 62 core samples were used for bottom sediments analysis and for determination of mercury content. Among these samples, only 5 core samples were used for this study in an attempt to clarify the relationship between the vertical distributions of benthic foraminiferal assemblages (Bulimina denudata) and mercury contents in core sediments. The distribution pattern of sediment median diameter and of the maximum mercury content at some layers of each core show that the fine-grained sediment polluted by mercury were transported both northeastward and southward by weak longshore currents and spread toward north and west across the northern and souhtern part of the South Yatsushiro Sea. Bulimina denudata shows the highest frequency at every layer which has high mercury content ranging from 0.14 to 3.46 ppm, and is comparatively low at all unpolluted layers. The frequency of Bulimina denudata slightly decreased at the layers showing more than 3 ppm. All these signals suggest that Bulimina denudata does not prefer the bottom sediments showing high mercury contents but tolerates mercury pollution.

Introduction : the problem faced in smoking fish is primarily related to deterioration of lipid caused by oxidation, that may cause of omega-3 fatty acid content in fish. This research was aimed at investigating the effect of different method of smoking fish to the organoleptic value, proximate composition and omega-3 fatty acid content. The experiment was carried out in The Laboratory of Coastal Zone Ecodevelopment, Diponegoro University, Jepara. Analysis of omega-3 fatty acid was conducted using Shimadzu Gas Chromathography in The Laboratory of Food Science and Technology, Tokyo University of Fisheries, Japan.
Material and Method : a randomized design was used in this study; filleted skipjack tuna (Eutynnus affinis); approximately 125 gr in weight and about 25 cm in length was used in both coconut shell for the traditional method and liquid smoke from Giulini Chemii for modern method. The temperature of the smoking process was between 40 – 80 °C. Sensory test and proximate composition were determined in order to support an omega-3 fatty acid analysis.
Result and Discussion : the average value of sensory test of traditional smoked tuna was between 3.00 – 8.33; liquid smoked tuna was between 6.67 – 9.00. the protein composition was 38.98% and lipid was 2.71% for the traditional product and 32.21% and 2.06% were obtained in liquid smoked tuna. Analysis of DHA resulted in 17.6% (traditional) and 20.9 (liquid). The results showed a significant difference between two products. The product of liquid smoked fish had better appearance, longer shelf life and higher omega-3 fatty acid content.

Susilowati, Indah
fisheries, resource, management, traditional, semi-traditional, modern, ikan larangan, features and attributes.
“Ikan larangan” is a kind of fisheries management system that applied closing seasons of fishing in a portion of river or canal for certain period. There are three types of ikan larangan’s management: (1) traditional; (2) semi-traditional; and (3) modern. The total sample of 99 household respondents were withdrawn from the three sites of ikan larangan, i.e.: (1) ikan larangan Lubuk landur (traditional, n=19); (2) ikan larangan Kayu Tanam (semi-traditional, n=20); (3) ikan larangan Pasir Lawas (modern, n=60). The study emphasizes more on the modern of ikan larangan system. This is in attempt to find out the possibility of implementing this system to other places in Indonesia as an alternative of resource management system and for food security purpose as well as for enhancing the fisheries sector and the regional developments. Furthermore, the co-management application of ikan larangan could encourage the implementation of decentralization policy in Indonesia since the system may able to help in empowering people and the available resources to generate the local income. Moreover, the salient characteristics of co-management system for ikan larangan could be adopted to prescribe the acceptable resource management for the similar circumstances of the resource in some places in Indonesia.

Chemical treatment; precipitation; public salt
The public salt produced by salt farmers in Juwana, Pat,i Central Java, Indonesia with the NaCl content of about 92.86% (dry base) is still below the standard quality of industrial salt (98.5% of dry base). Improving public salt quality has become an important topic of discussion. This research look into the influences of chemical compound, namely sodium hydroxide (NaOH), sodium carbonate (Na2CO3) and barium chloride (BaCl2) to reduce pollutant ion (Ca2+, Mg2+ and SO42-) in order to increase the percentage of NaCl content in public salt. The purification process was carried out in three series mixer. In this investigation, 100 ml of public salt solution is gradually treated by adding those compounds, which were varied from 0.50 to 3.50 gram with the step size of 0.50 gram. The results showed that the purity of NaCl could be enhanced up to 99.6% that was achieved by adding 2.00 gram o f NaOH, 1.50 gram of Na2CO3 and 2.50 gram of BaCl2. This purity is suitable to meet community and industrial demands

Brackish water, Desalination, Coastal region, Reverse osmosis.
Most of coastal regions in Indonesia have experienced water scarcity where water resources are becoming more and more threatened due to the rapid growth of population, aquaculture industries and agricultures. Brackish water reverse osmosis (BWRO) desalination may be used to overcome the supply potable water problem in the coastal regions. Brackish water having total dissolved solids (TDS) content in the range of 1,000–10,000 ppm can be desalinated at a reasonable cost. This work was aimed to find valuable technical data for plant design and operation. Cost analysis also was conducted to obtain specific water cost. The results show that stable system performance was achieved. Based on a case study of small scale BWRO with capacity of 50 m3/day, specific water cost was around of IDR 6,100/ m3.

Thane Creek-India, hypoxia, reclamation activities, increased nutrients and suspended solids.
Degradation of natural resources is a major environmental issue the world is currently facing. Estuaries, creeks and coastal water ecosystems are such natural resources that are important as breeding and feeding grounds for fishes and crustaceans. Human activities and alterations made by reclamation have had an adverse effect on their ecology. Due to this, water quality management in these ecosystems has become a necessity. Regular studies of the hydrological parameters are essential for this purpose, as they can assess the status of pollution and help in deciding the mitigation strategy.
Water quality of 26 km stretch of Thane creek, central-west coast of India was analyzed in 5 regions of the creek from May 1999 to April 2000. The study revealed spatial and temporal patterns. Heavy suspended solid load (avg. 5.736 gm/L), frequent hypoxia (DO<2.5 mg/L) coupled with excess nutrients like Phosphate-Phosphorus (avg. 0.26 mg/L) and Nitrate-Nitrogen (avg. 0.96 mg/L) were the main features of the creek.
The Thane city region showed more deterioration of water quality compared to the other regions in the creek. In this region the suspended solid load showed an increase of 713.69% and dissolved oxygen decreased by 21.55% compared to the data of 1992-93. This can be attributed to the severe onslaught of activities in this region like solid waste dumping, construction of 3 new bridges, etc. since 1993, thereby affecting the flushing characteristic. Hence in order to protect and preserve such ecosystems, alterations to the environment should be meticulously planned.

Coral reefs are the most diverse marine ecosystems; however, little is known about their microbialdiversity in these ecosystems. The present study is aimed at investigating the general insights into thediversity of the bacterial community associated with the coral Galaxea fascicularis. A culture collectionof 45 bacteria associated with coral G. fascicularis from Ujung Kulon, Indonesia was established byplating on Zobell’s 2214E. Isolates were screened by means of RLFP and sequencing of representative16S rDNAs. Using the restriction enzyme HaeIII, isolates were classified into 8 pattern group. Thesequence results indicated that a high diversity of bacterial phylotypes was present within the coralGalaxea fascicularis. In general, there are three major groups of bacteria: (i) members of the division Firmicutes , (ii) Actinobacteria, and (iii) γ-proteobacteria. Phylogenetic data on microbial communitycomposition in coral G. fascicularis will help in the rational selection of culture conditions to improvethe diversity of bacteria and the knowledge on the physiological, biochemical, genetic, and molecularproperties of coral bacteria.

GONAD MATURATION OF TWO INTERTIDAL BLOOD CLAMS Anadara granosa (L.) AND Anadara antiquata (L.) (BIVALVIA: ARCIDAE) IN CENTRAL JAVA
Afiati, Norma
Anadara granosa, Anadara antiquata, similar reproductive anatomy, spermatogenesis parallel the classical vertebrate pattern, continues spawning, planktotrophic iteroparous species.
The reproductive cycles of male and female Anadara granosa and Anadara antiquata which have been studied and compared by histological techniques showed great anatomical similarity. Gametogenesis is associated with a system of follicle cells which break down as the gametes approach maturity. The arrangement of follicle cells is characteristics of the sex. In the female, gametogonia are peripheral to the follicle cells, whilst in the male they are interstitial. The process of spermatogenesis parallel the classical vertebrate pattern, i.e. successive layers of spermatogenic cells (spermatogonia, primary and secondary spermatocytes, spermatids, and spermatozoa) occurring more or less regularly in succession toward the centre of the follicle. The diameter of the maximum size oocytes is 75mm for A. granosa and 65mm for A. antiquata. Spawning in both A. granosa and A. antiquata is progressing gradually throughout the year as indicated by the availability of various stages of oogonia and spermatogonia; for which the highest number of oogonia were those of 25-40mm diameter. The histological study indicated that both species are iteroparous with planktotrophic type of development, yet performing a short period of pelagic life (ca 1 month).

Distribution; benthic foraminifera; FORAM Index; Belitung islands
To check the feasibility of the environmental for coral reefs, several monitoring strategies exist, one of which making use of the foraminiferal community structure: FORAM Index, i.e. Foraminifera in Reef Assessment and Monitoring Index. The abundance of symbiont-bearing foraminifera should parallel coral abundance, if water quality is the major environmental control. This allows for the use of these foraminifera to quantify environmental quality with respect to coral health. The aim of this study is to study the benthic foraminiferal assemblages in coral reefs community and sea grass bad of Belitung Islands and to use that information to determine the environmental quality of their coral reefs based on FORAM Index. Sediments of Belitung Islands waters were sampled for their foraminiferal fauna at six sites i.e. Nasik Strait (four sites), Kudus Island and Bago Island on April 2010. Results of benthic foraminiferal quantitative analysis of the sediments in which collected from six sampling sites of Belitung Islands show that totally collected specimens 29 species of 18 genera. The most favorable place for coral growth is the free area (absence of coral, mangrove and seagrass) of Nasik Strait, but it only has 30 specimens of benthic foraminifera, with three species of symbiont-bearing foraminifera such as Operculina and Amphistegina. Whereas, the most abundant of benthic foraminifera is Nasik Strait 1 with typical substrate coarse sand and vegetated by coral reef. In other side, segrass bad of Nasik Strait is dominated by opportunistic foraminifera and only dwelled by Heterostegian, Calcarina, Elphidium, Ammonia, Acervulina, Spirolina, Quinqueloculina and Lenticulina. Moreover, the most abundant species of all sampling sites is Peneroplis pertusus.

MANGROVE AND ITS EFFECT ON THE DEVELOPMENT OF SMALL RUMINANTS IN THE COASTAL AREAS
Rahmadi, Didiek
mangrove, sheep, triglyceride, and protein total of plasma blood
Mangrove has as an important role in the coastal area. Thus, it must be managed properly. An experiment on its management was carried out in Morodemak villages, Bonang subdistrict, Demak district, central Java Province. Sheep owned by the fisherman were used as a material of the experiment. These were taking using purposive random sampling method. Sample was chosen from three different locations. It was determined on the basis of the distance from farmer housing to the mangrove areas. It was divided into three categories, namely: close: 0-2 km; medium: 2-4 km; and distant: >4 km). survey was done in order to collect data on mangrove, management system, and status of hematology (triglyceride and protein total of plasma blood) of sheep. The experiment was conducted by managing the sheep traditionally by giving them indigenous grass and leaf mangrove. There was no difference in the content of triglyceride and protein total of plasma blood of sheep managed at three different areas. This phenomenon occurred due to only the quality of leaf of mangrove, which has been fed to the sheep.

ANTIBACTERIAL ACTIVITY OF BACTERIAL SYMBIONT OF SOFT CORAL Lobophytum sp. AGAINST MDR BACTERIA Escherichia coli and Staphyllococcus aureus
Murti, Paulus Damar Bayu
Radjasa, Ocky Karna
Antibacterial ; Marine bacteria ; Soft coral Lobophytum sp. ; MDR
The improper and uncontrolled uses of antibiotics againts pathogenic bacteria have resulted in the occurrence of Multi Drug Resistant (MDR) strains. There is now an urgency to find alternative antibiotics to combat the MDR strains especially Escherichia coli and Staphyllococcus aureus. Soft coral associated microorganisms are among the most interesting and promising marine natural product sources which produce polyketide and non ribosomal peptide products with various biological activities. In this study, marine bacteria were isolated from soft coral Lobophytum sp. collected from North Java Sea, and were screened for antibacterial activity against MDR strains. One out of 13 bacterial isolates were succesfully screened and were found to be active against both MDR strains, in which isolate LBTGA2 was active against resistant strains E. coli and against resistant S. aureus, respectively. The active isolate also amplified PKS (Polyketide Synthases) gene fragments necessary for the biosynthesis of polyketides. The molecular identification based on partial 16S DNA nukleotide sequences indicates that the active isolate was closely related to Paenibacillus campinasensis.

BIO PROSPECTING MARINE HALOPHYTE Salicornia brachiata FOR MEDICAL IMPORTANCE AND SALT ENCRUSTED LAND DEVELOPMENT
Stanley, Oswin D
Salicornia - Bio prospecting - Medicinal values - Salt land Rehabilitation - Poverty Alleviation
Halophytes continue to be either under or unexplored in India. Many halophytic plants are of economic
value and have industrial applications in the form of essential oils, medicinal, alcohol, fiber, latex, pulp,
cosmetics etc. Salicornia spp extensively occur along Gujarat and Tamil Nadu coasts in the regularly
(20-50 tides month-1) inundated inter tidal zones. Expanding saline wastelands, dubious rains,
recurring droughts and soil erosion due to absence of green belt between sea and land ultimately lead
to low productivity and poverty in these coastal regions.
Seawater Agriculture is the strategy to link ecology and livelihood. Utilizing Salicornia to rehabilitate
the land and bio-prospecting biomedical compounds is a promising concept besides addressing the
issues of desertification, salt intrusion and ultimately poverty alleviation. It is rational to implement
pilot projects in different locations with commercial motives entangled with research concepts
standardization.

ZOOPLANKTON COMMUNITY STRUCTURE AT AWUR BAY IN THE NORTHERN CENTRAL JAVA SEA
Zainuri, Muhammad
Zooplankton abundance, diversity and community structure were estimated in the seagrass beds of Awur Bay, Jepara. The samples were collected during 36 hours observation in situ, from Nopember 1994 to April 1995 and covered a total 29 species, which holoplanoton, 7 meplankton and 6 nectobenthos.
Result of Shannon Weaver Diversity Index and Cluster Analysis based on Bray Curtis values revealed patterns of zooplankton abundance, diversity and community structure. These are discussed with regard to sampling time and zooplankton life cycle.
The zooplankton abundances range between 6800 – 22777 individuals/m3, with average 13698 individus/m3, while the diversity range between 2,48 – 2,86 and cumulatively 2,93. Zooplankton abundance and community structure fluctuated due to seasonal changes, during the first two months of the research, and increasing to a stable level in April 1995. This pattern of zooplankton community structure appears to be related to the ecological capacity and hydrodynamic.
Keywords : zooplankton, seagrass, abundance, diversity, community structure, Awur Bay, Jepara.

PRELIMINARY STUDY OF THE POTENCY OF SEDIMENTATION RATE IN BANJIR KANAL TIMUR SEMARANG COASTAL WATERS
Bachtiar, Tonny
Sediment, sedimentation, suspended, traps, and rate
Five sets of sediment traps were installed for thirty days (Oct.- Nov. 1999) in Banjir Kanal Timur Semarang coastal waters to examine the potency of sedimentation rate. Two sediment traps were lost in the second week of measurement. Based on the average data of three sets of sediment traps, the potency of sedimentation rate in Banjir Kanal Timur Semarang coastal waters was 6.10 cm/month. The result did not reflect the fact of the field condition. Based on the correction made on the input of suspended discharge into Banjir Kanal Timur Semarang coastal waters and the average area of sediment distribution, the potency of sediment rate in Banjir Kanal Timur Semarang coastal water during transition of dry season to rainy season was 0.35 cm/month.

proto reef, reef ball, coral, recruitment, restoration
Reef BallTM structure is a popular artificial reef module that has been invested in many countries. Publication on its efficacy in promoting coral recruitment however remains lack of study or publication. This present study was aimed to examine the pattern of coral recruitment on reef ball structure at the Benete Bay of Sumbawa Island, Indonesia. Thirty reef-balls (dome shape; 0.90 cm height, 1.20 cm diameter) were monitored after three years of deployment. The results of this study showed that nearly all coral colonies grew on the outer vertical surface and upper side of the reef balls. The recruit number varied a lot between 1-76 colonies per module. Most recruits were belonged to the Family Acroporidae, which contributed approximately 76 percent to the whole recruitment (640 colonies). Branching acroporiid was the most abundant colonies (55%). Pocilloporidae and Faviidae both contributed approximately nine percent to the total recruitment, while Poritidae contributed about three percent. Other coral families only had <1% contribution. The diameter of coral colonies which were growing on the reef balls varied between 5-290 mm. The number of recruit on the ball was very low at 10 meter depth (1-5 colonies per ball) that was likely to be affected by sedimentation. This study showed that reef ball module can be effectively used as a method in rehabilitating damaged coral reefs, and developing a proto-reef.

THE ECONOMICS OF VIOLATION BEHAVIOUR OF FISHERS IN INDONESIA, MALAYSIA AND THE PHILLIPPINES*)
Susilowati, Indah
Violation, non-compliance, fishers, zoning regulation, enforcement, Tobit, regulation, policy.
This paper examines the behavior of the fishers violating a zoning regulation under a condition of limited enforcement in the fisheries of Indonesia, Malaysia, and the Philippines. Rational utility theory is used as a framework for explaining compliance behavior. Samples of 304 violators from the study area were used in the analysis. Tobit model is employed in the analysis. The results indicate that economic, morality and social influence factors determine the overall violation decision of individual violators fishing in the prohibited area. In the general the findings of the study were consistent with the theoretical model of compliance behavior tested by previous researchers. Enforcement is costly thus to improve fishers’ compliance in the study area there is a need to used other determinants of compliance as such as morality and social influence factors. Fisheries management authorities should also explore alternative approaches for managing fisheries such as participatory or community-based management approaches. Such approaches may incur lower monitoring and enforcement costs.
rateB� R J��EER. The best absolute growth (292,05g), daily growth rate (1,34%/day), FCR (2,31), PER (1,68) and NPU (8,37), were achieved by treatment B, followed by C and A. meanwhile, the best SR was achieved by treatment C and followed A, and B.
Therefore, treatment B appeared to be the best fish feed formulation for Red tilapia production.

NEW MODIFIED EQUATION OF LONGSHORE CURRENT VELOCITY AT THE BREAKING POINT (FOR MIXED AND GRAVEL BEACHES)
Antoniadis, Christos
gravel, mixed beach, wave breaking, current velocity, longshore
Wave breaking is the dominant process in the dynamics of nearshore water movements resulting in sediment transport. The transformation of the subsequent particle motion from irrotational to rotational motion generates vorticity and turbulence and this affects the sediment transport. An improved understanding of the location of the breaker point and characteristics of the wave under these changing parameters is essential to our understanding of short and long-term morphological beach development.
This paper reports a series of 3-dimensional physical model tests to measure longshore current data, generated by oblique wave attack, along gravel and mixed beaches with a uniform slope and a trench. The studies described in this paper aim to improve the Longuet-Higgins’s formulae which predicted the longshore current velocity at the breaking point.

SPATIAL DISTRIBUTION OF Thunnus.sp, VERTICAL AND HORIZONTAL SUB-SURFACE MULTILAYER TEMPERATURE PROFILES OF IN-SITU AGRO FLOAT DATA IN INDIAN OCEAN
Hartoko, Agus
spatial distribution; subsurface seawater temperature; Thunnus.Sp; Indian ocean
The study was the first ever attempt in fisheries oceanography sciences to explore the empiric correlation
between the spatial distribution of tuna (Thunnus.sp) and sub-surface in-situ temperature data. By means of
optimalization and use of an in-situ data of both vertical and horizontal which will be processed into a
multilayer subsurface seawater temperature of ARGO Float in Indian ocean. So far only sea surface
temperature (with temperature around 29 °C) data were used to look for the correlation for tuna spatial
distribution, while the Thunnus.sp swimming layer as widely known is in about 80 – 250m depth with
seawater temperature between 15 – 23 °C. The noble character of ARGO Float data is as in-situ data
recorded directly by the sensors, transmitted to the satellite, transmitted to the ground station and ready to be
used by researcher all over the world.In the study, about 216 seawater temperature coordinates of ARGO
Float and actual tuna catch data in the same day were used to represent the dry season (April – November
2007) analysis, and about 90 data were used for the rainy season (December – March 2007). The actual
tuna catch and its coordinates data were collected with permission from PT. Perikanan Samudra Besar,
(PT.PSB) Benoa – Bali Indonesia. Then both seawater temperature and tuna data were processed using a
Krigging method or spatial interpolation method.Based on a monthly actual tuna production by fishing fleet
of PT.PSB operated in Indian Ocean indicates that there were two cycles of low catch in March and July and
high catch in May and December 2007. In general, seawater temperature in depth of 80m, 100m, 150m and
200m of the dry season was 2 °C warmer than those of the rainy season. Range of seawater temperature will
decrease due to the water depth, range of seawater temperature at depth of 150m was between 14 – 22 °C
and at depth of 200m between 12 – 20 °C. Based on the regression and correlation between tuna catch and
seawater temperature revealed that seawater temperature at depth 150m has the highest coefficient of
correlation than to the seawater temperature at depth 100m and 200m.

THE STABILITY OF FATTY ACID OMEGA-3 OF SALTED MACKEREL IN VACUUM PACKING
Ma’ruf, Widodo Farid
Salted fist, one of the products od processed fish, is produced by the application of high temperature so that its quality tends to decrease during storage. One of the factors contributing to quality deterioration is the chemical reaction involving lipids such as oxidation and hydrolysis. Oxidation is caused by the presence of and accelerated by other factors such as temperature. This reaction occurs easily in fatty acid omega-3, which is one of a number of unsaturated fatty acids Hydrolysis reaction is caused by lipase enzyme in fish body. Therefore, it is necessary to find an appropriate storage method to prevent lipid deterioration. This research applied low temperature to preserve salted fish. The study was aimed at investigating the influence of low temperature (4oC) as compared to ambient temperature on the stability of fatty acids omega-3 of salted mackerel fish wrapped in vacuum packing. Results showed that omega-3 content in mackerel varied with different storage temperature and period.

Dried salted anchovy, SDS-Page, Browning formation, Lipid oxidation
Dried salted anchovy is a rich source of protein which is processed by boiling, salting and drying. During processing the protein undergoes change, e.g. protein myofibril becomes denatured to some extent , and it can be visualised using SDS-PAGE protein pattern. Protein can also react with lipid to form brown colour mainly in high temperature. The result of the analyses shown that there were differences in proximate composition between different samples of anchovy. There were not much difference in sample band pattern for fresh , boiled , boiled and dried anchovy samples. The highest solubility protein was found in the Indonesian dried salted anchovy while the lowest was in fresh sample. The colour of boiled sample was the whitest in comparison to fresh, boiled and dried, Indonesian dried salted anchovy and Japanese boiled. Except for Indonesian dried salted anchovy, brown colour and development of lipid oxidation was not detected.

The aim of this research was to observe the effect of body size in micro algae as significant factor responsible to bioaccumulation of Pb. The research was conducted in Balai Budidaya Laut Hanura, South Lampung using micro algae Chlorella and Dunaliella, observing various Pb concentrations in culture medium and dry weight of micro algae to describe their tolerance and sensitivity levels. Pb concentration in culture medium was determined using AAS (Atomic Absorbance Spectrophotometer) and micro algae biomass observed by optical density approach. Effective concentration of Pb as growth inhibitor of Chlorella and Dunaliella was 50 and 150 μg/l. Dunaliella has greater absorption ability than Cholorella. Less bioaccumulation in Dunaliella indicated high tolerance level to Pb. Dunaliella, whose wider cell surface, has a greater bioaccumulation ability than Chlorella.

FRESH WATER PRODUCTION IN COASTAL AND REMOTE AREAS BY SOLAR POWERED LIQUID-LIQUID MEMBRANE CONTACTOR
Susanto, Heru
Wenten, I G.
flux, liquid-liquid membrane contactor, wind and solar energy
Liquid-liquid membrane contactor (LLMC) is a new desalination process using microporous hydrophobic membrane. The temperature difference at two solution-membrane interfaces gives rise to a trans membrane vapor pressure difference that drives the flux. In this work, the effect of process parameters on LLMC performance has been done. The process parameters consist of feed and permeate temperatures, cross flow velocity, feed concentration and mode of operation. In addition, this paper focuses on the development of LLMC by using solar and wind as energy sources. In this experiments micro porous hydrophobic hollow fiber polypropylene membrane with 0,2 mm was used as a contacting device. The experiment were conducted at temperature of 25-80oC, cross flow velocity of 0.02-0.2 m/s and solute concentration of 0-110.000 mg/L. Results show that the flux was influenced by the feed and permeate temperatures, the cross flow velocity and the concentration of solute. The increase of feed temperature increases the flux exponentially, whereas the flux seems to increase linearly with the increase of cross flow velocity. On the other hand, the flux was not significantly affected by the solute concentration. Furthermore, the flux in the counter current mode was lower than in the co-current mode. The average pure water fluxes obtained were in the range of 2-3 l/(m2h), whereas the products concentrations were in the range of 2-5.3 mg/L depending on the feed concentration. The operation of solar powered LLMC up to 10 days shows a very stable performance.

Mangrove ecosystems are important as they harbour a diversity of life forms. This study aimed at studying the benthic and arboreal macrofaunal diversity and abundance associated with three naturally occurring mangrove forests of Mauritius, Western Indian Ocean. The mangrove areas included Roches Noires, Mahebourg and Pointe Maurice, on the east coast of the island. The field study was carried out at low tide during summer season from October 2003 to February 2004. At each of the three sites, the arboreal and benthic macrofauna were sampled separately, using quadrats of 1 m x 1 m and 25 cm x 25 cm, respectively. Sixty-four benthic and 42 arboreal quadrats were collected from Roche Noires, 40 benthic and 41 arboreal quadrats at Mahebourg and 40 benthic and 30 arboreal quadrats at Pointe Maurice. The results showed that benthic habitat is more diverse with regards to molluscan families (24 families) than the arboreal habitat (5 families). Pointe Maurice has a more diverse benthic fauna. Relative percentage abundance and mean density of molluscan families are reported. Highest mean densities and relative abundance were recorded for the Family Littorinidae among arboreal macrofauna. In benthic macrofauna, the highest mean densities and relative abundance were noted in Family Cerithiidae at Roches Noires and Mahebourg.

The abundance and occurrence of a special group of bacteria, capable of solubilizing or mobilizing insoluble phosphates were studied in estuarine environment, especially in sediments. The possible role of various factors of the sediments in maintaining the phosphate availability in the overlying water was described. The phosphatase activity was recorded in all samples irrespective of salinity variations. Total number of bacteria showed higher value in lower salinity. The total phosphate content in soil showed positive correlation with the phosphatase activity ( r = 0.890; P-Value = 0.000; n-=15). Clayey sediment contents more phosphate solubilizing bacteria and phosphatase than sandy sediment in a tropical estuarine region of River Hooghly.

Marine crustacean waste, chitinase
Chitin is present in large quantities in the marine crustacean waste disposed by seafood processing industries, making it very desirable as the substrate for producing chitinase, a hydrolytic enzyme of considerable interest in many industrial and agricultural applications. In our work, crustacean waste powder and its combination with colloidal chitin at different concentrations (0.5, 1.0, and 1.5%) were utilized to optimize the chitinase production by the bacterium, Bacillus sp. K29-14. The results showed that the chitinase production with the three different substrate concentrations was relatively constant in the range of 0.2 to 0.3 U/ml during 12 days cultivation, although there was a bit reduction after day 8. This activity profile seems to be similar to that of the protein content. Whereas the chitinase production on the media containing crustacean waste powder and its combination with colloidal chitin at the three concentrations showed that the highest activity (3.0 to 4.6 U/ml) was achieved on day 7 and 8. The specific chitinase activity with the waste powder at different concentrations of substrate (0.5, 1.0 and 1.5%) was increasing slowly during a nine-day cultivation. The optimal chitinase production (4.6 U/ml) was achieved with the combined substrate of 0.5% on day 8.

tradition; sea thanksgiving; fishermen; symbol; culture.
Tradition of “sedekah laut” (sea thanksgiving) in the Pekalongan fishermen community is also “Nyadran” which is always celebrated every month of “Syuro”. This ceremony is the expression of gratitude to God having given safety and abundance of fortune in fish catching in the sea. In this tradition there are various manings, omens, symbols which can be used as philosophy of life for the fishermen. This tradition is unique and interesting; it is also the regional cultural wealth which should be preserved, especially for thourism interests.

The determination of bivalvae demographic structure were conducted in Rembang Waters, central Java. The samples were collected and observed in situ, from February to May, 1996 and coverd 3 species, which are Mactra sp., Solen sp. and Pholas sp.
The Von bertalanffy Growth Curve allows the determination of bivalvae population growth and their evolution. This is in regard to their presence according to sampling time and their abundances. The growth model was adjusted by several approaches, using the computer program, called DATAX . It was found that, the general pattern of bivalvae demographic structure was directly related to the ecological capacity and hydrodynamic factors of sampling area.

conflict ; fisheries ; resolution ; sea waters ; South Kalimantan
Conflict of fisheries (capture fisheries cases of purse seine) in the sea waters of Kotabaru South Kalimantan, require serious attention. The government has made some efforts to overcome it but not yet effective. Therefore it is important to know more deeply whether conflict resolution is already addressing the root of the problem. The study was conducted with a qualitative approach. The primary data collected through in depth interviews with key informants, while the secondary data obtained from literature studies, relevant agencies and newspaper clippings. Based on the analysis results that: the root causes of conflict based on the source of relationship issues, structural problems and value differences and conflicts based on the typology of conflict of jurisdiction, internal allocation and management mechanism. The resolution of conflict using negotiation and facilitation techniques. Conflict resolution is done is still not addressing the root of the problem so that the escalation of conflicts of fishing last long. Conflict resolution needs to be done effectively by involving stakeholders and increasing their participation in creating the sustainability of capture fisheries.

trophic structure, deposit feeders, Infaunal Trophic Index (ITI), Shanon-Wiener diversity index (H’), and environmental disturbance.
Sediment dynamics and the hydrodynamics of the environment cause the complexity and variability in
animal-sediment relationship, both in spatial and temporal. This study is focused on the response of
macrobenthic fauna to environmental disturbance caused by fish farming using their trophic structure.
Their changes in trophic structure can be used as an indicator of disturbance. Eight control sites and eight
farm pontoon sites were samped in a full year period. Two stations at each site were sampled five times
throughout the year with four replicates. Macrobenthic abundance was categorised based on six major
trophic groups: carnivores (CAR), herbivores (HER), omnivores (OMN), suspension feeders (SF), surface
deposit feeders (SDF), and subsurface deposit feeders (SSDF). The Infaunal Trophic Index (ITI) and
Shanon-Wiener diversity index (H’) were used to assess the degree of environmental disturbance caused by
fish farming based on trophic structure. The relationship between ITI and H’ was assessed using
Spearman’s rank order correlation (rho). The result showed that the abundance of deposit feeders was
significantly higher at the farm sites than at the control sites, suggesting that food availability is more
varied and abundant at farm sites than those at control sites. The results of the ITI indicate that the entire
sampling sites have been moderately disturbed over the sampling period, with the exception for site BC8.
Variability of Shanon-Wiener diversity index (H’) spatially and temporally seems co-vary with ITI, owing to
the influence of taxa richness and evenness.

Enforcement activities is important to determine the success of fisheries management. However, enforcement is costly for Indonesia which made up from many islands and has very long coastline. Therefore, it is needed to find the alternative with least in cost. One of the feasible alternatives is by empowering fishers and their communities to monitor and surveillance the fisheries resources in their adjacent. This system is rather using traditional concept of community-based or co-management.

The problem of seed production of Scylla serrata juvenile is the massive mortality due to cannibalism among them that normally happen when the animal undergone the molting. The density of juvenile and the feed play important role to avoid the cannibalism. The aim of the study is to understand the interaction between fresh feed and density in controlling the mortality of the juvenile reared in the laboratory scale. A factorial plot with three levels of treatments of fresh feed and three levels of juvenile densities was used in this experiment. The fresh feed treatment did not significantly influence either survival rate or growth rate of juvenile. On the other hand, the density strongly influenced the survival rate of juvenile but not to the growth rate.

HOUSEHOLD PROTECTION AGAINST DENGUE HEMORRHAGIC FEVER EPIDEMICS IN COASTAL CITY OF MAKASSAR
Halide, Halmer
DHF epidemics, predictive model, forecast value, decision making, DEET
The skill of two simple models for predicting Dengue Hemorrhagic Fever (DHF) epidemics in a coastal city of Makassar was evaluated. One model uses persistence while the other uses past dengue cases and climate factors to make predictions. It was shown that the skill of the models was not significantly different. The value of the prediction was also investigated when it was used for deciding whether or not to protect a household from epidemics. When the model predicts that a DHF epidemic was forthcoming, a highly effective but low-cost DEET product was applied to the whole family as protection against mosquito bites. It was found that the cost of implementing such model prediction was much cheaper than other options such as: (i) using protection without any forecast and, (ii) neglecting any protection. It was also found that the value of a forecast depends on forecast skill and the cost-to-loss ratio.

LABORATORY INVESTIGATION ON GRAVEL AND MIXED BEACHES DURING AN OBLIQUE WAVE ATTACK
Antoniadis, Christos
An experimental investigation into the behavior of gravel and mixed (sand and gravel) beaches was carried out at the 3-D Wave Basin located at Franzius-Institute (Marienwerder) of University of Hannover, at a nominal scale of 1:1. The experiment aimed to provide full scale measurements of cross-shore processes on gravel and mixed beaches, during an oblique wave attack, with uniform slope and a trench. Measurements included sediment transport, cross-shore beach profiles and wave-induced currents, for regular and random wave tests, for both types of beaches. Analysis of both cross-shore and long-shore currents shown interesting behaviour for both gravel and mixed beach, especially at the trench. There were morphological differences between the two types of beach concerning the crest and the step formation, the onshore sediment movement, and the erosion below the SWL, concluding the general difference of their mobility.

The research of stock analysis of Metapenaeus elegans was held in Segara Anakan Lagoon, Cilacap Central
Java. This research were aimed to study the carapace length of optimal capture, exploitation rate optimum
and maximum sustainable yield relative. The research were carried out by using survey method and the
sample were collected by systematic random sampling method. Sampling conducted over 11 months, from
February until December 2004. Data was analyzed using ELEFAN in FiSAT II software. The result show
that rate of exploitation of M. elegans was 0.83 / year, and the length of first capture of the M. elegans was
14.5 mm. At 14.5 mm carapace length, the rate of exploitation (E) should be 0.51 / year, and E0.1 was 0.47 /
year. The average biomass of exploited for 24% of the initial biomass, which has exceeded the ideal limit of
10% (E0.1 concept). According to the above three indicators (the carapace length of shrimp, exploitation rate
and biomass used), then the exploitation of M. elegans in Segara Anakan Lagoon has been considered
seriously over-exploited. The rate of exploitation has reached 154% of Emsy and 177% of E0.1. Based on
simulation results, the size of carapace length of first capture that produces the MSY is a minimum carapace
length of 21.3 mm, and the rate of exploitation (E) can reach 0.7 / year.

Dried noodle; seaweeds puree subsitution ; quality; sensory evaluation
The objective of this study was to compare dried noodles made of different type of seaweeds puree and then were compared to noodle which was made without any seaweeds puree subsitution. Different seaweeds puree (E.cottoniii, G. verucossa and mixed beetween them) were subsituted in proportion of 30% in the noodles. The results showed that subsitution of seaweeds puree increased the moisture, crude fiber, ash and iodine content of dried noodles compared to noodle without seaweed puree. The moisture contents : 10.08 ± 2.02 to 13.94% ± 0.84, fat 1.26 ± 0.22 to 2.49 ± 0.81%, crude fiber 2.00 ± 0.4 to 2.25% ± 0.18 and carbohydrate contents 63.37 ± 3.8 to 68.47 % ± 1.5. Iodine concentration in dried noodle with seaweed substitution about 1.06 ± 2.80 to 1.43 ± 0.76 ug/g, protein content 11.84 ± 1.03 to 12.42 ± 0.40 and the carbohydrate content 63.37 ± 3.80 to 68.47 ± 1.59. Significantly tensile strength (p<0.05) were found between the treatments of dried noodles. Higher water absorption by the seaweed lead to softer and spongier textural intensities in the noodles. However, different pattern was observed in the protein and carbohydrate content. The subsitution of different seaweeds puree did not give any significant influence (p>0.05) only for to the taste and colour of dried noodles.

This study was the first attempt to examine the molt stage and molting cycle in relation to the ovarian development of M japonicus in Tokyo Bay In particular the study was done to reveal molting and spawning relationship, to predict reproductive peaks and thus larval recruitment and to investigate the possibility of multiple spawning within one molt cycle in natural condition, Ohh: three out of five stages were represented in the samples since the early premalt (A) and ecdysis (E) occured in a very short time. There occured was a co-occurrence between ovarian maturation and molt stage, in which maturing ovaries occurred at B (late postmolt) to D, (earlv premolt) stage, mature ovaries at C (intermold to D; (late premoly, and spent ovaries at D, to D,. Molting and spawning synchronization was observed in kuruma prawn, in which molting fequency was highest prior to and at the end of spawning season. There was a possibility of multiple spawning within single molt cycle in wild kuruma prawn, since there were enough time for spent ovaries to redevelop into mature ones.

Study on the chaetognaths of the Baguala bay waters, Ambon island has been done at approximately monthly intervals during January to March and May to September 1994. Sampling was carried out during the day time by using a 200 µm meshed WP2 zooplankton net at 7 fixed stations. Eleven species of chaetognaths belonging to the genus Sagitta and 2 other species (Pterosagitta draco and Krohnitta pacifica) were recorded. A total of 23,960 individuals of chaetognaths were examined and of these 4,546 individuals contained prey in their guts. The copepods were the dominant prey of Sagitta enflata, accounting for 73.80% of the diet. It was found that the food containing ratio (FCR) of stage 2 of S. enflata was higher than the other stages, while the number prey per chaetognath (NPC) of stage 3 of S. enflata was higher than other stages, and the daily feeding rate (DFR) of S. enflata (all stages) recorded at stations in the mouth of the bay was slightly higher than at stations inside of the bay. The FCRs, NPCs, and DFRs of P. draco were lower than S. enflata, therefore the impact on the copepods community structure would be greatest in this season and the stations in the mouth of the bay.

THE EFFECTS OF DIFFERENT WATER FLOW RATES ON THE SURVIVAL RATE OF BLUE CRAB (Portunus pelagicus) ZOEA IV - MEGALOPA STAGES
Rejeki, Sri
blue crab (Portunus pelagicus), zoea IV – megalopa stage; water flow, survival rate
Blue crab (Portunus pelagicus) is a potential marine crustacean’s commodity. The increase demand both local and international market of the blue crab result in the culture development of this species. The larval stage of blue crab, especially at zoea IV to megalopa, plays an important rule on the successful of the production of marketable size under culture condition.Low survival rate of zoea IV to megalopa stage mostly due to their photo taxis behavior, thus, they are trapped at the water surface. Management of water flow rate on the zoea IV holding tank may be able to reduce their mortality rate and can reach megalopa stage successfully. The water flow rate management would keep the zoea in the suspension as well as improving the water quality, i.e. increases the dissolved oxygen in the water.This investigation was done to find out the effects of different water flow rates on the survival rate of blue crab (Portunus pelagicus) zoea IV stage. The tested animal was blue crab at zoea IV stage which undergoes an investigation up to megalopa stage. An experimental method with a Completely Randomized Design was applied. The 5 (five) treatments of different water flow rates were used, i.e.: A (0,25 l/minute), B (0,5 l/minute), C (0,75 l/minute), D (1,0 l/minute), E (0,0 l/minute). Each treatment was replicated three times.The results shows that different water flow rates gave a highly significant difference (P<0,01) on the survival rate of blue crab zoea IV - megaloga stage. The highest survival rate at the end of the experiment (at megalopa stage) was at treatment C (0,75 l/minute): 30,44%

Smoking duration, quality, DHA, milkfish
Milkfish contains omega-3 fatty acids (DHA), which is very important to maintain the health of human being. The research is mainly aimed to evaluate the reduction of DHA composition during smoking process. Organoleptic value of the product i.e. : 8,1 for fresh fish; 8,59 for smoked fish A (3 hrs smoking duration) and 8,78 for smoked fish B (5 hrs smoking duration). The composition of fish changes normally i.e. moisture content of 75,03% (fresh fish) decreases to 70,08% (A) and 68,11% (B). Protein composition increases from 20,30% (fresh fish) to 23,95% (A) and 27,50% (B). Lipid content increase from 0,61% (fresh fish) to 1,79% (A) and 3,53% (B). Ash content changes from 1,35% (fresh fish) to 2,03 (A) and 1,89% (B). SPSS analysis of DHA found of p < 0,05 means that A and B were significantly different. DHA content was found drastically decrease from 121,19 mg/100g (A) to 16,4 mg/100g (B). ANOVA result proved that there is an interaction between smoking duration and the composition of DHA. Smoking duration is recommended no longer than 3 hrs in order to maintain its quality and minimizing the reduction of DHA.

Muhaemin, Moh
glutathione, diurnal cycling, Dunaliella salina
Glutathione is intracellular low molecular weight thiols as detoxification agent in most marine microalgae. The short continuous culture was used to describe diurnal cycle of intracellular glutathione during light: dark period. The result showed that glutathione tend to follow light period and minimum levels at the end of dark period. Cysteine exhibited twofold diurnal variations, maximum levels at the early dark period. Those may prove that glutathione may have an important role as an antioxidant in marine phytoplankton.

A local isolate of green algae called C1 from Jepara waters is usually used as a source for carotenoid supplement for animal fisheries in the local area. This indigenous algae has been successfully purificated. Although the local isolate was known as eucaryotic green algae Dunaliella, our previous molecular study by 18S rDNA analysis to determine the species of this organisms showed negative result. In order to improve carotenoid production especially detection of biosynthetic pathway from the organisms investigated in this study, the main purpose of this study was species determination of local isolate of green algae based on microbiologycal, ecophysiologycal and molecular characterization.
The results of this research indicated that local isolate of green algae posseses Cyanobacteria characteristic, especially Synechocystis. Analyses with 16S rDNA sequence from genome of green algae isolates were also in accordance with these results, showing close similarities with Synechocystis 16S rDNA sequence. However, it should be noted that, instead of having Synechocystis dominant feature, it was also found that local isolate of green algae exhibit different characteristic in having chlorophyll a, chlorophyll b and lack of phycobillins. This character was typical for abberant Cyanophyta, Prochlorophyta.

EMPOWERING COASTAL COMMUNITY BY IMPLEMENTING NATURAL RESOURCES MANAGEMENT (Case study in Southeast Sulawesi, Indonesia)
Sara, La
Hamid, Abdul
., Safilu
Empowering ; coastal community ; natural resources
Economic crisis in 1997-1998 had brought about the emergence of problems of coastal communities in Indonesia, including those in Southeast Sulawesi. Most of the problems still have taken place at present, leading to the degradation of ecosystem services for natural resources. Development activities in various sectors done through unsustainable practices of utilization of natural resources have contributed to increased environmental degradation , which resulted in drastically decreased on fish population. Recently, the government and people are aware that integrated natural resources of coastal and marine management have to be set based on scientific approach. There have been several strategies formulated. Among them is integrated coastal zone management, but unfortunately it has been using top down approach. Hence, local community has no access to the programs. The effective implementation of empowerment should involve all stakeholders who have access to the coastal resources. The objectives of this work were to reduce gradually coastal resources degradation, to change fishermen behavior using illegal fishing, and to create new job using natural resources. This work was implemented in Lasongko Bay of Buton island. The present work is formulated to reduce social economic problems, which has strong correlation with environmental degradation. The programs were formulated by local community in several discussion forums based on identification of their natural resources. To alleviate poverty, rehabilitation of environmental degradation was done first which consisted of planting mangrove seeds along shoreline of the bay and establishing marine protected area. Another program implemented was fish and seaweed cultures to improve community income. The local community in groups took full participation and involvement in all programs implemented due to the role of religion and traditional figures and youth leaders. To achieve the objectives and goals of the programs, each group had a leader and held monthly meeting to discuss strategies for better life. All programs implemented showed better hope for the future due to active participation of local community in maintaining all programs of environment rehabilitation. Similarly, activities of improving income also showed better production.

SUSTAINABLE MANAGEMENT OF MRINE TOURISM: SOME ECONOMIC CONSIDERATIONS *)
Davis, Derrin
marine-tourism, coral reef, management.
Marine tourism is a rapidly growing phenomenon world-wide. Concerns arise that important marine resources, such as coral reefs, are used sustainably for recreation and other pursuits. A number of possible management strategies exist that might contribute to such result should considers the followings:
• property-rights;
• user-pays;
• regulation;
• education and code of conduct;
• permanent mooring;
• socio-economic research.
It is also clear that no one management strategy will ensure that Indonesia’s significant coral reef and other marine are conserved and used in sustainable fashion. Rather, a judicious blend of the use of economic instruments and concepts, regulation, education, and “site-hardening” (e.g. by use mooring) is required to ensure that marine tourism is sustainable.

Antioxidant; DPPH; fiber content; phenol content; seagrass
Extracts of methanol, ethyl acetate, and n-hexane of four species of Indonesian seagrasses were used to determine the total phenol contents and their antioxidant activities. Total phenol contents of each extract was determined by spectrophotometer using Follin-Ciocalteu reagent, and the antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH). The profile of fibers of each fresh seagrass was performed according to an enzymatic-gravimetric method. All of methanol extracts contained high number of total phenol, except Syringodium isoetifolium the highest content was found in ethyl acetate extract; so that methanol extracts of Thalassia hemprichii, Cymodocea rotundata, Enhalus acoroides and ethyl acetate extract of Syringodium isoetifolium had the highest activities on scavenging DPPH radical. The phenol content in tropical seagrasses was tending to soluble in polar and semi-polar solvents. There was no significant different on the content of total fibers, with values ranges was from 14.32 g/100 g to 15.39 g/100 g. However, the highest content of soluble fiber was found in Enhalus acoroides (8.93 g/100 g) and significantly differed to others.

This experiments was conducted as response to the serious negative impact of shrimp aquacultres into the environment. The shrimp-Gracillaria polyculture system was hypothesized to reduce excess pollutant in the shrimp pond. Variation in Gracillaria density was used as treatments. Two important aspects are discussed in this paper, that are the effect on shrimp productivity and efficiency in carbon energy conversion into harvestable products. There were significant evidences that the shrimp-Gracllaria polyculture system increase the sizes, total biomass, survival and growth rate of shrimp. The density of Gracillaria was positively correlated with all of those parameters. The carbon energy conversion was also significantly affected by Gracillaria density. The carbon energy conversion into harvestable products was more efficient if Gracillaria density was increased.

The aim of this research was to evaluate the quality of two different SCR products come from different coastal waters of seaweed culture. The products were then compared to commercial SCR on the quality based on their chemical quality (Fourier Transform Infra Red, sulphate content and heavy metals) and physical quality (gel strength and viscosity). The method of FTIR was useful as a quality screening for commercially seaweed culture at different geografic places based on their chemical structure.
Raw material that have been used for SCR product was Eucheuma cottonii with k-carrageenan type. FTIR spectroscopy showed the molecular present in three different samples are quite similar, it can be found spectra band of 1257,59 cm-1 which referred to esther sulphate, 933,55 cm-1 for 3,6 anhydrogalactose and 848,68 cm-1 assigned to galactosa-4- sulphate respectively. The SCR product from different coastal waters were different on their quality.

Quality of surimi (minced meat of fish) usually decrease due to denaturation of protein. Addition of cryoprotective agent such as reducing sugar as anti denaturation of protein is very important during storage of frozen surimi. Recently, development of human lifestyle require healthy food such as utilization of stevia sugar (Stevia rebaudiana) which has low calorie that can be used to replace sorbitol and sucrose during processing of surimi. The purposes of this research are to observe the effect of different cryoprotective agents before and during storage as well as the effect of storage on quality of frozen surimi fish based on pH value, water holding capacity (WHC), gel strength and organoleptic value. Materials used was surimi made from kurisi (Nemipterus sp.), stevia sugar, sorbitol and sucrose. Research method used was experimental laboratory with research design of Completely Randomized Design with split plot in time. The main plot was difference of cryoprotectant (stevia sugar 0.6%; sorbitol 4%; sucrose 4%). The product was analysed every 15 days starting from 0 to 45 days storage at – 10oC. The results showed that different cryoprotectants agent gave no significant effect before storage treatment proceed. In addition during storage, the different of cryoprotectant gave significant effect to WHC and gel strength (SSS=1356,416; SS=1458,525; S=1511,307 g.cm) but not for pH. The organoleptic value for appearance on 15 days storage was SSS=7; SS=7; S=6,56 and Folding test showed SSS=7; SS=7.78; S=7,89)

Indonesia has a great endeavor in fisheries resources. However, most of the resources remain underutilized in some extents. At the same time, resources disparity is occurred in Indonesian fisheries. Tight competition among the resource users happen in fisheries with dense population. In such situation, thereafter, tragedy of common phenomena will happen. Managing fisheries resource in the condition which constitutes thousands of islands like Indonesia is not an easy task and should be quit costly in expenses. One of strategies that require less in cost and could promise a better achievement is through reviving the potency which belongs to the community (such as traditions, customs, beliefs, etc.) and with empowering community to manage the fisheries resource.

LAND USE, TAMBAK OWNERSHIP, AND TAMBAK CULTIVATION A CASE STUDY OF “SUMBERSARI” IN NORTH CENTRAL JAVA
Kistanto, Nurdien H.
Land use, plywood factory, agriculture, brackishwater pond
The establishment of the plywood factory in “Sumbersari” has changed the pattern of land use. As in many other north coast villages along the Java Sea, agricultural land can be divided into two major categories, namely tambak (brackishwater ponds used for aquaculture) and sawah (irrigated land used for wet-rice cultivation). Landholders may thus own tambak and/or sawah. Tambak can be further divided into tambak bandeng (milkfish brackishwater pond) and tambak udang bago (giant-tiger shrimp brackishwater pond). Both can be farmed alone or they can be combined, which is locally called tambak campuran (mixed brackishwater pond). Tambak bandeng are sometimes further differentiated from tambak ipukan (fry pond), a smaller type of tambak designed for nursing milkfish fry to fingerlings. Still another type of tambak, which is only a portion of an irrigation stream or canal where landless peasants trap fish and shrimp with a bamboo fence, locally called tambak kali (canal pond).

Benthic foraminifera, sediment, marine division, population
Bottom sediments were collected from 74 stations in the South Yatsushiro Kai (Sea), Japan using gravity corer in March 1996. Aimed at clarifying the relation between living benthic foraminiferal assemblage and environmental conditions, the Q-mode cluster analysis was carried out based on the predominant species of living benthic foraminifera recognized at the topmost one centimeter of 73 core samples.
The results of this study show a trend of a large number of living benthic foraminifera is found in central part of the sea, on the other hand, a small number is seen in the northern and southern part. The study area is characterized by 469 species of living benthic foraminifera belonging to 114 genera.
In relation to the five divisions of the marine environment based on oceanographic data, mechanical analysis data and sedimentation rates, the foraminiferal assemblages in the South Yatsushiro Kai were grouped into five populations. Population I occupies the areas near the straits under the influence of strong tidal and bottom currents. Population II occupies the areas surrounding the straits (Gannoshiri Seto and Kurono Seto) influenced by water masses flowing through the straits. Population III occupies the areas of rather stagnant water masses in the northern and southern parts of the sea. Population IV occupies the areas located in the northeastern and southeastern parts of the sea, and influenced by river waters. Population V occupies the nearshore area located in the northeastern, and influenced by the water masses which flow southward from the North Yatsushiro Kai.

A total of 90 bacterial isolates were obtained from association with sponges collected from Bandengan water, Jepara and Karimun island of Karimunjawa islands in the north java sea. Antibacterial screening by using a pathogenic Escherichia coli indicated that two isolates BSP.12 and MKSP.5 inhihited the growth of tested strain. Molecular identification based on 16S rDNA approach revealed that isolate BSP.12 was closely related to Vibrio harveyi with a homology of 100% and isolate MKSP.5 showed highest similarity to Brachybacterium rhamnosum (99%), respectively.A PCR-based approach by using specific primers targeting the occurrence of gene fragments necessary for the biosynthesis of major natural products, namely Non-ribosomal peptide synthetases (NRPS) and Polyketide synthases (PKS) was applied to estimate the genetic potential of these active strains. Both isolates were capable of amplifying the NRPS gene fragments but not the PKS gene fragments.

A bacterium, collected at the surface of coral Acropora sp., TAB4.2 was successfully screened for secondary metabolites production based on PCR amplification of the non-ribosomal peptide synthetase gene. It was identified as closely related to Pseudoalteromonas luteoviolacea based on its 16S rDNA. TAB4.2 was found to inhibit the growth of all 5 coral-associated and all 5 pathogenic bacteria tested. To characterize the inhibiting metabolite, a 279 bp long DNA fragment was obtained and the deduced amino acid sequence showed conserved signature regions for peptide synthetases and revealed a high similarity to NosD (40 % identity), a multifunctional peptide synthetase from Nostoc sp. GSV224, and NdaB (44 % identity), a peptide synthetase module of Nodularia spumigena.
�m es�`� ��� on their ecology. Due to this, water quality management in these ecosystems has become a necessity. Regular studies of the hydrological parameters are essential for this purpose, as they can assess the status of pollution and help in deciding the mitigation strategy.
Water quality of 26 km stretch of Thane creek, central-west coast of India was analyzed in 5 regions of the creek from May 1999 to April 2000. The study revealed spatial and temporal patterns. Heavy suspended solid load (avg. 5.736 gm/L), frequent hypoxia (DO<2.5 mg/L) coupled with excess nutrients like Phosphate-Phosphorus (avg. 0.26 mg/L) and Nitrate-Nitrogen (avg. 0.96 mg/L) were the main features of the creek.
The Thane city region showed more deterioration of water quality compared to the other regions in the creek. In this region the suspended solid load showed an increase of 713.69% and dissolved oxygen decreased by 21.55% compared to the data of 1992-93. This can be attributed to the severe onslaught of activities in this region like solid waste dumping, construction of 3 new bridges, etc. since 1993, thereby affecting the flushing characteristic. Hence in order to protect and preserve such ecosystems, alterations to the environment should be meticulously planned.

A bacterium which utilizes chlorpyrifos as a sole source of carbon and energy was isolated from coral surface. The organism utilized chlorpyrifos up to 25 mg l-1. The lag phase and time for degradation, however, were severely prolonged at chlorpyrifos concentrations above 10 mg l-1 . The growth of kinetics of coral bacterium was studied in batch culture. Estimation of maximum growth rates (μmax), obtained from turbidity measurements, was 0.14 h-1 and half-saturation growth constant (Cs) was 9.34 mg l-1 chlorpyrifos. This strain demonstrated greatest similarity to members of the order Bacillales and was closest to members of the Bacillus firmus group.

THE ASSESSMENT OF SENSITIVITY OF BIOTIC INDICES IN DETERMINING SYMPTOMS AND LEVELS OF DISTURBANCE USING MACROBENTHIC ASSEMBLAGE DATA
Putro, Sapto Purnomo
environmental disturbances; univariate index; multimetric index; degree of sensitivity; AMBI and EQR
a large number of techniques, including a variety of indices, have been proposed and developed for
assessment. Structural and functional variability have been summarized through both univariate and
multimetric indices as integrative indicators in environmental monitoring programs. In general, multimetric
indices are considered to be sensitive, stable, and robust, thus offer a promising approach for ecological
assessment. This study is aimed to assess the degree of sensitivity for several indices in terms of their ability
to determine environmental changes. Based on macrofaunal data, several univariate and multimetric indices
were used to assess and compare the level of disturbance at fallowed farm and reference (control) sites. The
two multimetric indices, the AZTI’s Marine Biotic Indices (AMBI) and Ecological Quality Ratio (EQR), were
used as integrative indicators to assess the categorisation of each sampled site. The results showed that a
combination of multimetric index and univariate indices provide a better assessment. The categories
determined by multimetric indices seem to be in accordance with level of disturbance expressed by the
trophic analysis, multivariate and graphical analyses used in this study. The AMBI has the ability to detect
large scale differences among sites. However, AMBI was unable to discriminate slight changes in the
macrobenthic assemblages between sites, as have been exposed by EQR.

Zooxanthellae (Symbiodinium sp) from the giant clams, Tridacna maxima, were monitored for their responses to ammonium and phosphate addition in the field. Nutrient was added into ponded microatolls at every low tide using Nutrient Dispersal units (NUDs) moored outside the atolls to reach final concentrations of 10 µm for ammonium and 2µm of phosphate. Transmission electron micrograph showed that zooxanthellae size (as the maximum diameter) from nitrogen-treated clams was significantly than those from other treatments (P<0.05). However, the cross sectional area of the nucleus was not significantly affected by the treatment smaller (P>0.05). The results suggests that the condition of zooxanthellae, such as the size of zooxanthellae from giant clams is influenced by relatively small changes in the concentration of nitrogen in the water column.

Coast ; SIG ; Landscape
Development is a changing process to improve human standard of life that strongly related to the activities of natural resource utilization. It is frequently found that these activities change the ecosystems and their resources. Eventually, these changes will give serious impacts to the environments. The most distinct environmental problems are caused by resident migration to the coastal areas, coastal developments, and land limitation. Coastal reclamation is an example of human effort to respond to the land limitation in the coastal areas as observed in coastal areas of Labakkang Subdistrict. Reclamation activity is doing along the coast of Pundata Baji Village, whereas, in other villages, cutting off of mangrove areas as an alternative land expansion is increasingly practiced by the local communities. This Research was aimed to observe the landscape change from 1980 to 2010 at coast area in Labakkang Subdistrict. Each review considers Landsat Image Map (acquired in 1980); Landsat Image Map (acquired in 1990); Landsat Image Map-7 Enhanced Thematic Mapper Plus (ETM+) (acquired in 2000); Spot Image 4 (acquired in 2005); and Spot 4 LAPAN (acquired in 2010). Result of research indicates that at coast area of Labakkang Subdistrict in 1980, there are 248.3 ha of mangrove vegetation, 2,756.63 ha inundation, and 4,157.0 ha open land. In 1990, there are 234.2 ha mangrove vegetation, 2,251.63 ha embankment, 933.2 ha rice field, and 582.0 ha open land. In 2000, there are 218.3 ha mangrove vegetation, 2,848.1 ha embankment, and 3,579.2 ha rice field. In 2005, it has 121.4 ha mangrove vegetation, 3,762.6 ha embankment, and 2,306.2 ha rice field. In 2010, it is found 48.9 ha mangrove vegetation, 5,029.35 ha embankment, and 749.98 ha rice field.

STATUS OF MANGROVES IN MAURITIUS
Appadoo, Chandani
Department of Biological Sciences, University of Mauritius, Reduit, Mauritius http://www.coastdev.undip.ac.id
Array
Mangroves play an important role in the coastal ecosystem of Mauritius. Two species of mangroves, Bruguiera gymnorrhiza (L.) Lam., and Rhizophora mucronata Lam., have been identified so far. The latter species is more dominant and occurs in pure stands in most of the swamps. Loss of biodiversity due to the destruction of wetlands, mangroves and corals is one of the priority issues identified in the National Environment Strategies. Mangrove and Coral reef management and protection is one of the key strategies in addressing coastal zone challenges in Mauritius. Very few scientific studies exist on mangroves in Mauritius. Currently there are no scientific studies on the fauna and flora inhabiting mangrove ecosystems. This is an area that requires further research. Therefore a lot of work remains to be done with regards to the mangroves. Moreover, future management programs will need to look into the factors threatening mangrove ecosystems.

GROWTH INHIBITION OF MEDICALLY ANTIBIOTIC RESISTANT BACTERIA BY SPONGE-ASSOCIATED BACTERIA
Radjasa, Ocky Karna
antibacterial, marine bacteria, sponge Haliclona sp., MDR
The improper and uncontrolled uses of antibiotics against pathogenic bacteria have resulted in the
occurrence of Multi Drugs Resistant bacteria. There is now an urgency to find alternative antibiotics
to combat these bacteria. The metabolites from microorganisms are a rapidly growing field, due, at
least in part, to the suspicion that a number of metabolites obtained from algae and invertebrates may
be produced by associated microorganisms. Therefore, there is a shift in the search for secondary
metabolites from terrestrial to marine environment. Sponge-associated microorganisms are among of
the most interesting and promising marine natural product sources, which produce polyketide and non
ribosomal peptide products with various biological activities. In this study, marine bacteria were
isolated from sponge Haliclona sp. collected from North Java Sea, and were screened for antibacterial
activity against MDR strains. One out of 32 bacterial isolates were successfully screened and were
found to be active against MDR strains, strain Escherichia coli and strain Proteus sp., respectively.
These active isolates were also capable of amplifying NRPS gene fragments necessary for the
biosynthesis of non ribosomal peptides. The identification results revealed that the active isolates are
Arthrobacter sp.

Fishers, Compliance, Pemalang, Model, Enforcement, Co-Management
The study was conducted due to high incidence of non-compliance by fishers in Central Java fisheries. The overall objective of the study is to examine the compliance behavior of fishers in Pemalang Regency. Eighty-five (n=85) respondents have been selected from the study areas using multi-stages sampling method. Moreover, key-persons from Fisheries Office, Navy and head of fishers’ association have also been interviewed to enrich the analysis of the study. Non-compliance behaviour of fishers in this study was viewed from violation of: restricted area (zoning), restricted gears and means (explosive and poison) and administration (such as permits). Model of non-compliance behavior as outlined by Kuperan (1993) and Susilowati (1998) has been applied to analyze the data in this study with necessary modification. Tobit model explained by Gujarati (2003) was employed as the estimation techniques.
Most of independent variables such as demographical factors, fishing effort, deterrence indicators and legitimacy variables have expected signs although statistically are not always significant. In general, the model of non-compliance behaviour could portrait the phenomena of violation behaviour of fishers in the study area. It is realized that law enforcement in Indonesian fisheries is weak for several reasons. Therefore, to improve the fishers’ compliance perhaps an alternative approach such as empowering the people and its stakeholders should be found.

Among the 59 isolates only 4 Lactobacillus isolates were selected for further study. Based on morphological and biochemical characteristics, the isolates were identified as Lactobacillus sp. The pathogen were isolated from infected cat fishes, characterized and identified as Vibrio parahaemolyticus, Aeromonas sp and Aeromonas salmonicida. The Lactobacillus isolates were screened for antagonistic activity against Aeromonas, Vibrio sp. by agar diffusion assay. Among the 4 isolates, Lactobacilli RLD2 showed significant antagonistic activity against Aeromonas and Vibrio sp alone. and was further evaluated by standard plate count assay for the viability of pathogen. The isolate was multiplied and the fish feed was supplement with Lactobacillus isolates. The results reveal that the size, weight of the fish was statically increased in comparison to that of control fish. The present study concluded that the Lactobacillus isolates could be used as probiotic bacteria in aquaculture, to manage aeromonasis.

MITIGATION MEASURES FOR GAZA COASTAL EROSION

Gaza fishing harbor, morphodynamic, artificial reef, remote sensing
Coastal erosion is an ongoing hazard affecting Gaza beach, but is worsening due to a wide range of human activities such as the construction of Gaza fishing harbor in 1994-1998. The net annual alongshore sediment transport is about 190×103 m3, but can vary significantly depending on the severity of winter storms. According to the observed wave heights and directions, the net waves are cross-shore, therefore vast quantities of sediments may transfer to deep sea. The main objective of this study is to mitigate the erosion problem of Gaza coast.
Change detection analysis was used to compute the spatial and temporal change of Gaza shoreline between 1972 and 2010. The results show negative rates in general, which means that the erosion was the predominant process. Gaza fishing harbor caused a serious damage to the Beach Camp shoreline.
Consequently, several mitigation measures were considered in this study, which are: relocation of Gaza fishing harbor to offshore, groins, detached breakwaters, wide-crested submerged breakwaters and beach nourishment. Several numerical model tests associated with coastal structures are conducted to investigate the influence on morphodynamics.
The results show that the relocation of the harbor is the best alternative to stop trapping of the sediments. If for any reason the relocation was not carried out, the wide-crested submerged breakwater alternative is an effective structure for preventing sandy beach erosion. The artificial reef type of submerged breakwaters with beach nourishment is recommended for Gaza beach, because it is an environmentally friendly and improving the ecosystem of marine life.

A 2D geoelectrical resistivity method was used for detecting and mapping occurrence of salt/brackish water in the subsurface, North Kelantan - Malaysia. The North Kelantan plain is covered with Quaternary sediments overlying granite bedrock. The drainage system is dendritic with the main river flowing into the South China Sea. The geoelectrical resistivity surveys made up of eleven resistivity traverses at four different sites. The zone of brackish water is very clearly seen in the resistivity inverse model with position around 20-30 m depth. This aquifer is referred to second aquifer. As the final result, a map with the possibility of salt/brackish and fresh water interface can be generated.

Dewi, Eko Nurcahya
fish fillet, freezing, frozen storage, salt soluble protein, drip loss, isoelectric focusing sarcoplasmic protein pattern
Freezing is an effective method of preservation which can produce high quality foods. However, low temperature applied during processing could results in serious product quality deterioration in particular functional properties of protein. During the freezing process salt concentration increases and the change in pH may cause extensive denaturation of muscle protein. The process of denaturation can be accelerated with a resulting increase in thaw drip loss of tissue. In order to examine protein quality, parameters such as soluble protein, drip loss, and changes in the electrophoretic pattern of sarcoplasmic protein of fish muscle were studied. The fish used in this experiment was rainbow trout (Salmo gairdneri). The fish was filleted and frozen in an airblast freezer for an hour at -30°C. They werecalled “fres quality samples”, whereas the “poor quality” samples were fish fillets that have been kept on ice for 3 days before freezing. The samples were analysed for salt soluble protein, thaw drip, water holding capacity and isoelectric focusing of sarcoplasmic protein at the day and the freezing day storage (5 weeks). There was a decrease of 70% on the “fresh quality” sample from the initial value of 82.8% AND 7.5% the “poor quality” sample from 82.5% on the salt soluble protein. Although the differences were small and there were no significant difference between the two samples, the result suggests that of the protein became denatured during frozen storage (5 weeks). There was an increase from 4.3% to 11.6% in “fresh quality” and 6.9% to 12% in “poor quality” sample. The drop of these values reflect the extent of protein denaturation due to ice crystal formation and cell rupture. Sarcoplasmic protein pattern of both sample were not much different before freezing, however there was a disappearance of some light sarcoplasmic bands in the sample after freezing process. On further storage (5 weeks) the pattern obtained were still nearly the same, but light bands did not correspond exactly in their position.

Corrosion rate, copper, iron, seawater, resistance measurement
Copper and iron metal wire corrosion in artificial sea water have been investigated in three corrosion systems, in the (i) closed bath, (ii) opened or air exposed bath, and (iii) aerated bath. The aim of our investigation is to determine the effect of oxygen contained in the air to the metals’ corrosivity. Artificial sea water was prepared by dissolving 173.59 g sodium chloride and 4.91 g potassium chloride in 7.00 kg of water at 230C.The corrosion experiment was carried out under the constant temperature of 32 0C. Decrease of metal masses during corrosion was monitored by measuring the metal resistance change. Our experiment provided the corrosion rate in g.cm-2.s-1 as 4.01 x 10-7 (in closed bath), 4.01 x 10-6 (in opened bath) and 9.43 x 10-6 (in aerated bath) of copper metal, and 2.12 x 10-6 (in closed bath), 5.99 x 10-6 (in opened bath), and 1.07 x 10-5 (in aerated bath) of iron metal. Experimental results show that air oxygen give strong effect on the corrosion of copper and iron metal

THE SAPE STRAIT CEPHALOPOD RESOURCE AND ITS RESPONSE TO CLIMATE VARIABILITY
Ghofar, Abdul
Cephalopod, squid, climate variability, ENSO, southern oscillation index (SOI)
Of seven cephalopod species occurring in the Sape Strait, four species of squid constitute 90% of the annual cephalopod catches. The squid fishery is described, with emphasis on its fluctuating catches due to the combined effects of fishing and climate variability. Two most important fishing gears, ‘bagan perahu’ and ‘jala oras’ were used and standardized in catch and fishing effort analysis. The southern oscillation index (SOI) was used to represent the climate variability component.
A model was then developed by means of incorporating the SOI, fishing effort and squid catch. Average annual values of these three components were used to construct the model. The model can be a useful tool for predicting the squid catches. Its use for forecasting and managing the fishery requires regular monitoring the catch, fishing effort and the SOI, preferably monthly. Research and management implications of this finding are discussed.

EVALUATION OF THE THICKNESS AND THE LINEAR EXPANSION OF FISH CRACKERS PRODUCED BY SOME COTTAGE INDUSTRIES OF JEPARA DISTRICT (CENTRAL JAVA)
Ibrahim, Ratna
Dewi, Eko Nurcahya
., Sumardianto
Fish crackers, thickness, linear expansion
Fish crackers are locally known as “kerupuk ikan”. The quality of fish crackers depends on the thickness of the slice before frying, the percentage of linear expansion, and some other factors. So far, there was not any standard value of the thickness and the percentage of the linear expansion of good quality fish crackers in Indonesia yet.
The objectives of this study were to gain some data on the thickness and the percentage of linear expansion of fish crackers and to compare the data with the estimated ideal value based on the reference data.
Ten cottage industries in Jepara district chosen based on the proportional stratified randomized sampling method. The first grade fish crackers (according to the processor) were obtained as the samples from each of the cottage industries. Ten fish crackers of each sample were evaluated.
The results indicated that the fish cracker samples were circular, the thickness varied from 1.0 to 3.85 mm. The average thickness of the samples was 2.77 mm which significantly thicker (p<0.01) than the estimated ideal thickness (1.50 mm). The percentage of linear expansion of the samples varied from 54.48 to 134.58 %

CHELATING ABILITY OF CRAB SHELL PARTICLES AND EXTRACTED ACETAMIDO GROUPS (CHITIN AND CHITOSAN) FROM Portunus sp TO LEAD (Pb2+)
Muhaemin, Moh
Lead (Pb2+), Chitin, Chitosan, Portunus sp, Chelating ability
Various toxic metal species, including lead, are produced rapidly by industrial activities and fossil fuelconsumption. The use of biological component as sorbents for heavy metals might be an alternativemethod to reduce a heavy metal concentration from various aqueous systems. Here, we used crab shellparticles and extracted acetamido component from Portunus sp (chitin and chitosan) to reduce theconcentration of lead (II). The crab shell was powdered, sieved, and added with lead (II) in various pHvalues. The lead (II) solution added to extract of chitin and chitosan was separated, to determine thechelating ability of them. The result showed that the removal efficiency of lead with crab shell depend onpH value, but it was less sensitive than that of the control without crab shell. Biosorption of chitin andchitosan showed different phenomenon. It showed that both chitin and chitosan absorb with the bestcapacity at pH 4.0. Chitosan has higher sorption than chitin for all treatments.

INSTITUTIONAL CHANGE AT LOCAL LEVEL: HOW GILI INDAH VILLAGERS BUILD AN EFFECTIVE LOCAL GOVERNANCE OF CORAL REEF MANAGEMENT?
Hidayat, Aceng
Analysis of institutional change, awig-awig, local governance, distributional conflict theory, level of institutional analysis
This paper aims at explaining the process of institutional change in coral reef management at the village level, and mainly seeks to answer two research questions: How do the processes of local institutional change take place? What are incentives that drive local communities to participate in them? Investigations in Gili Indah village, West Lombok Indonesia show that the process of the institutional change was initiated and done by villagers whose livelihood strongly depend on coral reef ecosystems. There are also strong indications that the changes were affected by the local and external economic conditions, which inevitably force resource users and economic actors to alter their economic strategies. The entering of industrial tourism and the emergence of tourism-related livelihoods in Gili Indah has driven economic actors to adapt to the altering environmental condition. Tourism Business Operators (TBO) and fishermen, two main actors, have played important roles in the change process. TBOs, whose livelihood depends on coral reef ecosystems, have a strong interest in protecting the ecosystems from degradation. The same goes for the fishermen, who claim themselves as main beneficiaries of coral reef ecosystems, and insist on maintaining the status quo as an attempt to protect their economic interest. Two different economic interests have been incentive for an evolution process of local institutions (awig-awig) to construct a governance structure that accommodates the varied economic interest. So far, this governance structure has been effectively forcing the actors to comply with the rules that drive themselves to use the coral reef ecosystems in a sustainable way.

demersal/ benthic, shrimp-fishery, spatial-analysis
Semarang coastal waters is part of coastal zone at the north coast of Java that is still has their characters for coastal demersal fishery. It was known for a long time before, that Semarang coastal water is a very good fishing ground especially for some valuable demersal species, such as white shrimp (Penaeus merguiensis), (Metapeneus.sp); flat fishes (3 species); Gastropods : Tiger snails (Babylonia.sp) and Bivalves : Anadara.sp. Some study that had been developed earlier in transforming from individual station data at coastal and seas, into visual-spatial layer in order to give more accurate spatial analysis of multiple parameters in the invisible coastal waters. This study present further development in the analysis of multi-layer spatial analysis. The samples of demersal coastal shrimp fishery and its closely related ecosystem parameters (depth; sediment; salinity) were taken randomly to represent the area of Semarang coastal zone. Field ecosystem and fishery samples data then processed using spatial method known as Kriging, and overlaid on a Landsat_TM satellite data. The study develops especially a multi layer of the field variables approach in order to analyze possible spatial multiple correlations between ecosystem parameter, such as type of bottom sediment, depth, and salinity to spatial distribution of shrimps spatial distribution as to represent demersal coastal fishery. This benthic fishery resources is regarded as the most vulnerable fishery due it’s sensitive character ie. sedentary and limited movement, is a good example to be used to monitor the impact of the environmental changes such global warming and climate change, such as seawater temperature anomaly in Semarang Coastal water (was found 1.39 ºC in March 1983) for the adaptation strategy in the future coastal resources management.

THE ENVIRONMENTAL AND SOCIAL IMPACTS OF INDUSTRIALIZATION: LESSON FROM CENTRAL JAVA
Hadi, Sudharto P.
industry-growth-environmental and social consequence
In many developing countries, industrialization is considered as the best way to achieve the economic progress. The general pattern of long-term development of Indonesia’s fifth five year development plan is expected to bring about fundamental changes in the economic structure from agriculture to industrialization. A policy of encouraging industrialization is considered as a means of stimulating the national rate of economic growth, providing employment opportunities and raising the general standard of living of the poor. To support this policy, each municipal government is encouraged to build industrial zones intended to attract and facilities foreign and domestic investors. This research is to identify the environmental and social impacts of industrialization by using two different places of industrial zone as case studies. The impacts studied include environments, socio-economic and socio-cultural.
Industrialization as a strategy for economic development has been successful in terms of its contribution to improve Gross Domestic Product (GDP). The industrial sector could create employment opportunities to a particular segment of the population: young, single females. Industrial activities do not create much value added for local people. In fact, local people are adversely affected, threatened by job loss and decrease of daily income.
The environment consequences emerged include floods, lack of clean water, water pollution, air pollution, odour, dust, and noise. The indication of social impact is weakening community ties. The household associations in impacted villages are likely to conduct regular meeting as was previously was the habit.

Coral reef is a productive ecosystem with high biodiversity in the sea and being targeted to find a useful bioactive compound. However, the serious problem in development of bioactive compounds from marine invertebrate is the supply problem, because to get a small amounts of active compounds a massive numbers of sea organisms are needed. Tunicate is an animal in coral reef ecosystem that produces many bioactive compounds with pharmacological activities, such as, antibacterial, antitumor, and anticancer compounds. It has been reported that bacterial symbionts of coral reef invertebrates may synthesize the same compounds as the host. The purposes of this research are to isolate and to identify microbes which have antibacterial activity against MDR bacteria based PCR 16S rRNA and to detect the existence of PKS and NRPS biosynthetic gene fragments from tunicate bacteria of Didemnum molle. Out of 15 bacterial isolates, one isolate showed antibacterial potential against Escherichia coli and Staphylococcus sp. Molecular identification result showed that TS2A5 bacterium has a homology of 99 % with Virgibacillus sp. strain GSP17 16S ribosomal RNA gene. This isolate was also capable of amplifying NRPS gene fragment.

SIMULATION MODEL OF THERMAL WATER DISCHARGE EFFLUENT FROM THE STEAM ELECTRICAL GENERATING POWER PLANT “TAMBAK LOROK” AT TANJUNG EMAS HARBOR POND SEMARANG
., Sunarsih
Simulation model, thermal effluent, diversity index.
Simulation model is built for simulating the residual chiller which has now become hot water discarded through an outlet to Tanjung Emas harbor pond. The discarded water is called “thermal effluent” and will cause changes in sea temperature in surrounding areas.
The figuring of the casual relationship among those factors is carried out by developing a subsystem model and building it from the model’s subsystems to make a big system. It shows the complexity of the water effluent model. To know the immensity of the effect of each factor and relationship with the simulation of the model. One chooses an approach in the analytical method of dynamic system which uses the program “Powersim version 2.01” copyright 1993 – 1995 ModellData U.S.A.
The result of model simulation showed that the temperature effect on the physical-chemical characteristics will improve the water condition with diversity index and will decrease according to the temperature condition with respect to time.

THE PROSPECT OF CO-MANAGEMENT IN MANAGING OPEN WATER AND ESTUARIES RESOURCES WITH SPECIAL REFERENCE TO INDONESIA: A LESSON LEARNED
Susilowati, Indah
community, resource, management, co-management, open access, Indonesia, Java.
Indonesia is a maritime country, composed about 17,500 islands. It has a great endeavor of open water
resources such as river, lake, dam, pond, swamp, etc. which are spread over the country. Multi-tribes and –
races are attributed to its habits, tradition, and culture of the communities lived. Given such large territory,
especially Indonesia is formed of thousands island, it will be costly to set a formal enforcement and
surveillance in securing the open-access resources (like fisheries, water, etc). Fortunately, each community
has an indigenous or traditional system to manage the resources. For example: Ikan Larangan (in West
Sumatra), sasi (in Maluku), Subak (in Bali), Sedekah Laut (in Java) and so on (Susilowati, 1996; 1999).
Rather than waiting a complete formal resource management (and need to be set up by the government) and
do not know when will be effectively apply, thus it will be more reasonable and timely to revive the
traditional system of resource management belongs to the respective community. In short, community
involvement in resource management is urgently encouraged, particularly in developing country with
limited budget like Indonesia. This paper is attempt to compile an experienced of Co-management approach
to manage the open water resource done by Susilowati (1999, 2002, 2004, 2006, 2007). An institutional
analysis (Pomeroy and William, 1994) and Pinkerton (1989) with necessary modification were applied to
the respective studies. The results indicated that there is a fairly prospect to empower the competent
stakeholders (community, government, private, independent parties) to be involved in managing the openaccess
resources. However, all parties need to be encouraged for a high intention in participation,
commitment and somehow to create their sense of belonging to advocate the resource management. It is
easy to say but hardly to be materialized all the things for Indonesian context, except the leaders (formal and
informal) in the respective region are really committed to conserve the resource.

osmotic response, Tiger shrimp (Penaeus monodon), broodstock, molting
The attempt to optimize shrimp culture production has faced with several problems related to its biotechnical management, which was suspected unable to meet the needs of the cultured species. This is primary because the ecophysiological characteristics of shrimp, particularly those related to the osmoregulation mechanism in connection with their growth, have not been sufficiently understood.
The research was aimed at studying the ecophysiological characteristics of tiger shrimp (Penaeus monodon) involved in biotechnical management of shrimp hatchery with special emphasis on the osmotic response and isosmotic medium requirement for adult spawners in various molting stages.
The results showed that osmotic responses were closely realted to the salinity of water medium and molting phases. It was also found that the minimum osmotic works of tiger shrimp occurred in isosmotic medium, i.e. 34 – 35 ppt for premolt, 33 – 34 ppt for molt and 30 – 31 ppt for intermolt stages.

LUPIN MEAL UTILISATION IN AQUACULTURE FEEDS
Sudaryono, Agung
lupin meal, Lupinus spp., aquaculture feeds
The paper review nutritional value and production of lupin meal and its uses in aquaculture feeds. Feed is the major cost variable in a aquaculture system representing up to 60% of total operating costs. The utilization of cost effective feeds would improve profitability of a aquaculture business. Commercial aquaculture feeds have been traditionally based on fish meal as the main dietary animal protein source and soybean meal as the dietary plant protein source. Lupin meal as an alternative dietary protein source has a favorable amino acids profile as compared to soybean meal. Lupin meal is consistently available, cost effective, palatable and highly digestible to most species of fish. It has been demonstrated that lupin meal will replace a considerable amount of soybean meal with no loss in production and fish performance. Manganese and methionine levels must be considered when utilizing high level of lupin in aquaculture feeds. Lupin meal is comparable nutritionally with soybean meal, it is more cost effective.

FECUNDITY AND THE BODY LENGTH OF RAG WORM, PERINEREIS CULTRIFERA (GRUBE 1840) FROM WEARLILIR BEACH WATERS, SMALL KEI ISLANDS, SOUTHEAST MALUKU DISTRICT
Rettob, Martha
Polychaeta, Perinereis cultrifera, Fecundity, Body Length, Reproduction
The knowledge of fecundity is an important aspect in the reproductive biology. Understanding the fecundity may allow the estimation of the number of rag worm individual and the determination of the number of rag worm in the questioned length class. The number of egg released represents a linking chain for one generation to next generation.
The objective of research is to understand the range of fecundity, the range of body length, and the relationship of fecundity and body length of rag worm from Wearlilir waters, Moluccas, Indonesia. Achieving this objective, the observation to 238 individuals of female rag worm which are captured at Wearlilir beach waters, Small Kei Islands, Southeast Maluku District for a year from June 2010 to May 2011. The fecundity is calculated with the mixed methods including volumetric, gravimetric, and arithmetic.
The relationship between fecundity and body length of rag worm is following the square function, F = 144.6533PT1.2911. It can be transformed into a form of natural logarithm to produce the regression equation: ln (WF) = 4.97434 + 1.29109 * ln (WP). Result of linear regression analysis of variance indicates that there is a positive relationship between the fecundity and body length. This relationship is not so close because only 26 % fecundities are influenced by the length, while 74 % are influenced by other factors such as environment and food.

RECENT FORAMINIFERAL COMMUNITIES IN MAKASSAR STRAIT
Rositasari, Ricky
Distribution, foraminifera, Makassar Strait
Makassar strait is the very unique waters, the bottom topography was steep and complex, the waters mass
was also exceptional since Indonesian through flow carried flavor water from Pacific warm pool to the area.
To describe the exceptional of Makassar Strait hydrological characteristics through recent foraminiferal
community structure as a proxy, Oceanographical Expedition in Makassar Strait was conducted in October
2004. Research Vessel of Baruna Jaya VII was used to carry out the research activities. Sediment layers are
an essential tool on recording hydrological information in such period of time, and each certain layer
preserved certain information as a bench mark data at a time period. The result shows that there are 5
genera of planktonic foraminifera which generated a bulk in sediment surface. Deep chlorophyll maximum in
oceanic region of Makassar Strait was prominent factor generated living planktonic foraminifera in research
location. Benthic community was formed by 164 species from 78 genera. Water depth was affected to benthic
foraminiferal diversity, distribution and species diversity, which reveal that water depth was limiting factor
to benthic foraminiferal assemblage. Uvigerinid was the important taxa which make up 46 to 57 % of the
benthic specimen, particularly in river input yield adjacent area. Uvigerina asperula may considered as an
indicator of OMZ (Oxygen minimum zone) in Makassar Strait.

A knowledge of wave run-up behavior on a coastal structure is one of the most important factors affecting the design of coastal structures exposed to wave attack. Prediction of wave run-up on a coastal impermeable structure with slope face and various friction factors are discussed with simplifying assumptions. An analytical approach is given for predicting wave run-up based on data measurements as the parameters of incident waves entering to coastal structure. Statistical approach with Weibull distribution is given on prediction of wave run-up, and present the probability distribution of wave run-up height.

IMPACT OF HEAVY METALS CONTAMINATION ON THE BIODIVERSITY OF MARINE BENTHIC ORGANISMS IN JAKARTA BAY
Takarina, Noverita Dian

heavy metals ; contamination ; biodiversity ; benthic organisms ; Jakarta bay
Alteration of land is continuing to increase inorganic matter to marine ecosystems and reduce marine biodiversity. Therefore, we investigated the interplay among land use and heavy metal (Cr, Cu, Pb, Zn) inputs from 8 rivers of Jakarta Bay to the benthic biodiversity. At current time, land uses surrounding Jakarta Bay are fulfilled with industrial activity, settlement, and agriculture. Total concentration of Cr, Cu, Pb, and Zn were determined using the Atomic Absorption Spectrometry in order to assess and compare contamination levels among land use types. Results showed that the average concentrations of heavy metals in sediment were generally higher in river-mouth received water from industrial than those in agriculture. Those land use related metal pattern were also reflected in the benthos diversity. Macrobenthic community diversity decreased when inputs of organic matter increased. Decreases in macrobenthic diversity were mainly linked to an increasing abundance of species with specific functional traits, specifically deposit–feeding polychaetes. Our finding confirmed that land use in the form of industrial areas were potential to produce toxic material to ecosystems. Therefore, we recommend that the development need to consider the allocation of physical infrastructure particularly near waterways.

., Dirhamsyah
CBM, Seed funds, Village grants, AIGA, and CRMP
The Coral Red Rehabilitation and Management Program (COREMAP) is a I5-year program of the Government of Indonesia. It has been working at several sites in Indonesia since /998 to achieve sustainable use of coral reefs through the delegation of management authority to local communities. The establishment of epective models for participatory and community-based management is the core of this program. The model for community-based management includes community participation. community capacity building, promotion of alternative income generation, establishment of coral red management plans, community marine sanctuaries and community red watcher programs. This paper describes the experiences and lessons learned in Phase I of the COREMAP Project in implementing community—based red management at Senavang and Lingga Islands, Riau Province. It is argued that the involvement ofthe community in the planning and implementation process of coral reef management will improve the management and conservation of coral req' ecosystems. It is hoped that the Indonesian experience will contribute to the comparative literature on coral req' management.

INTERACTIONS OF SQUID AND SMALL PELAGIC RESOURCES IN THE ALAS STRAIT, INDONESIA
Ghofar, A.
small pelagic, squid, interactions
Small pelagic and squid fisheries of the Alas Strait in Indonesia are compared, to explore potential interactions between major components caught, which may then be taken into management consideration. The data time series used for analysis were taken from major fishing harbours and landing places, and go back as far as 1970s.
The small pelagic fishery in Alas Strait is mainly targeted upon squid (mostly Loligo edulis) by means of ‘jala-oras’ (payang-type) fishing, which is also used to catch small pelagic fishes during squid-off season. The small pelagic catches consist primarily of lemuru (Sardinella lemuru), tembang (Sardinella fimbriata), layang scad (Decapterus spp), and kembung (Rastrelliger spp), which are usually taken by various pelagic fishing gears. There was a general increase in the small pelagic catches from around 4,000t in 1976 to nearly 12,000t in 1990, after which a considerable fluctuation occurred, reaching a level of 8,000t in 1999. Squid catches increased steadily from <100t to 1,700t prior to1978 due to “jala-oras” boat motorization, but fluctuated sharply afterward. Another peak catch may be observed to approach 1,900t in 1997. During this period of large fluctuation, again, the landings of small pelagic fishes tend to replace squid position.
There is a strong indication of the existence of interaction between squid and small pelagic fisheries. In general the overall small pelagic exhibits a strong linear relationships with a correlation coefficient, r, of 0.5270 (highly significant). More specifically their species components also shows even stronger correlations, with coefficient correlation of 0.5898, 0.6686 and 0.6358 respectively for layang, kembung and lemuru. Interactions of the species group and their substantial implication in fisheries research and management are discussed in this paper

Distribution of 90Sr concentrations in surface seawater of Japan Sea has been studied from 30 June2000 to 18 July 2000. The concentrations of 90Sr varied according to the stations position and didn’tshow correlation with temperature and salinity. Distribution and level of 90Sr concentrations wereinfluenced by any factors such as distance from the sources of radionuclides and water current. Thestrong system of Tsushima Warm Current System and Kuroshio branch Current System in the Japan Seaincreased the leaching of 90Sr from the bottom sediment. The results of this study were much lower thanthose of previous study, presumably due to 90Sr characteristic will decrease with time and in theenvironment, it becomes incorporated with calcium. However, data in 1990 increased dramatically aseffect of Chernobyl nuclear power plant accident.

GROWTH RATES OF THE MASSIVE CORAL Porites lutea EDWARD AND HAIME, ON THE COAST OF BONTANG, EAST KALIMANTAN, INDONESIA
., Supriharyono
Coral growth rate, massive coral’s growth
Growth rates (linear skeletal extension) and the timing of skeletal band formation were measured in eight specimens of the massive coral Porites lutea at three sites (BK1, BK2, and BK3) and three depths, i.e. 1 m , 3 m, and 5 m in each site. The sites were located in Bontang Kuala Regency, located about 7.5 km from the fertilizing industry, PT Pupuk Kaltim Tbk, Bontang. Growth rates were measured by using two techniques, i.e. X-radiograph and UV-light.
Result of the study indicates that the timing of the high density (HD) and low density (LD) bands is synchronous at the three locations. A one year growth is characterized by three HD bands, one of which is usually very dense. Illumination of the coral slabs by UV-light revealed a distinct fluorescent banding pattern on all coral specimens. The data indicate that the fluorescent bands are usually associated with the high density bands which are accreted during the wet season period. It is characterized by high land run-off containing elevated concentrations of fulvic and humic acid compounds, and this apparently occurred almost through out the year. However fluorescent bands were absent from a number of density couplets, known as “stress bands”. The results suggest that in the present study the linier skeletal extension rates, based on X-ray radiographic techniques, are a more accurate measure of P. lutea growth rates then fluorescence banding.
Comparisons of the skeletal extension rates indicate that the growth rates of P. lutea are not significantly difference (p > 0.05) either between sites or depths. The average of coral growth rates ranged from 0.8-1.2 cm/year. These are significantly correlated (p < 0.01) with the amount of rainfall. While the amount of rainfalls is not correlated with urea production of fertilizing industry, P.T.Pupuk Kaltim Tbk, which some of them are loss as dust (a core for water vapour) during process production.

Resilience index ; coral reef ; Indonesia ; management
Ecological resilience is an important property of natural ecosystem to be understood in coral reef management. Resilience of Indonesian coral reefs was assessed using 2009 COREMAP data. The assessment used 698 data of line intercept transects collected from 15 districts and 4 marine physiographies. Resilience index used in the assessment was developed by the authors but will be published elsewhere. The results showed that coral reefs at western region had higher average resilience indices than eastern region, and Sunda Shelf reefs had higher resilience indices than coral reefs at Indian Ocean, Sulawesi-Flores, or Sahul Shelf. Four districts were found to have coral reefs with highest resilience indices, i.e. Bintan and Natuna (western region), and Wakatobi and Buton (eastern region). Raja Ampat had coral reefs with lower average resilience indices than that of Wakatobi. Uses of resilience index in coral reef management should be coupled with other information such as maximum depth of coral communities.

COASTAL ZONE MANAGEMENT IN INDONESIA : ISSUE AND APPROCHES
Dahuri, Rokhmin
The coastal zones and their embodied natural resources are a frontier area that offers Indonesian nation opportunities and challenges to enhance its economic development on a sustainable basis. Being the largest Archipelago State in the world, Indonesia is endowed with abundant and diverse coastal and marine resources. As natural resources on land are becoming scarce or difficult to develop, marine and coastal resources will be an importance resource for sustaining Indonesian economic development in the twenty first centuries. Furthermore, the shift of the global economic center from Atlantic to Pacific Rim will inevitably increase the use of Indonesia’s marine and coastal areas for various development activities, especially sea communication and transportation, fisheries and aquaculture, tourism, mining and energy, maritime industry, and coastal and offshore engineering.
However, experience in developing marine and coastal resources during First Long-term Development Period (1969-1994) have resulted not only in economic successes but also caused environmental degradation at a level which threatens the sustainable capacity of marine and coastal ecosystems to support further Indonesia’s economic development. Case like water pollution in highly populated or industrializes areas, overfishing of some fish stock, physical destruction of important coastal ecosystems (especially mangrove and coral reef), and coastal resource use conflict among coastal users indicate such a threatened condition. In addition, the majority of coastal communities are still lingering on absolute poverty.
The paper critically identifies and analyses the root of the problems, which threatens the sustainable capacity of coastal ecosystems, and suggests an alternative development paradigm provides a framework for reorientation of Indonesia’s development policies and programs with respect to coastal and marine resources to achieve sustainable development for the utmost benefits of all Indonesian people.

Diatom; palaeoreconstruction; stratigraphy; mangrove; Central Java
The natural mangrove ecosystems along the Northern Coast of Central Java were very limited in extent, even had replanted almost twenty years ago. Naturally, the upper layer of sediment are the latest deposition (superposition). Environmental condition recently are recorded in the top sediment layer, and can be used to reconstruct past condition (the present is the key to the past). The potential use of diatoms to reconstruct palaeoecology is well established. Diatoms are microscopic algae that form siliceous frustules which make them well preserved in sediment. Diatoms and their assemblages are very useful as integrated indicators of environmental changes because their distribution is closely linked to water quality parameters as well as their affinities to several physical habitats. This research was conducted in order to determine the changes of mangrove ecosystem in the Northern Coast of Central Java based on diatom stratigraphy. Sediment samples from mangrove sites were taken from Pekalongan, Brebes, Semarang, Demak and Rembang. Diatom analysis, consist of digestion, preparation, and identification. The diatom stratigraphy was performed by Software of C2 1.5.1. Stratigraphycally, the mangrove ecosystems along the Northern Coast of Central Java were previously more influenced by freshwater rather than the marine sources which dominate today.

During summer of August 2000, the behavior of 210Pb was studied in off coast Ulsan, Gampo and Pohang
waters, Korea as an area potentially upwelling occur. Water samples were collected vertically inshore and
offshore at each station. The highest of 210Pb activity occurred in the surface layer as derivate from
atmosphere and then decreased with increasing depth. The lower 210Pb activity in bottom layer was caused
by scavenging of particulate matter and strong affinity of unsupported 210Pb to soil and sediment particles.
In middle layer of the water column activity of 210Pb fluctuated due to water masses of North Korea Cold

MILKFISH BRACKISHWATER POND CULTIVATION: A CASE STUDY OF TAMBAK BANDENG IN “SUMBERSARI”
Kistanto, Nurdien H
Brackishwater pond; fish cultivation; coastal village
Milkfish brackishwater pond (tambak bandeng) in “Sumbersari” can be divided into three types: (a) fry pond; (b) brackishwater pond type 1; and (c) brackishwater pond type 2. Milkfish brackishwater pond cultivation is profitable, especially when the area is large. The idea of cultivating giant tiger shrimp (udang bago) in the brackishwater pond by using a mixed (campuran) method appears to generate considerable additional income for those who practiced it.

K value, FTP III, milk fish (Chanos-chanos, Forsk), short-bodied mackerel (Rastrelliger neglectus), storage temperature
Freshness of fish is crucial in determining the nutritional value and sale value of fishery products.
Assessment of fish freshness can be done with various methods based on several principles of chemistry,
physics, microbiology, and organoleptic. K value is one of freshness test based on ATP degradation.
Analysis of K values can be done with Freshness Testing Paper (FTP III). This method is relatively
practical, easy, fast and the results can be accountable. The material that used in this study are fish milk fish
(Chanos chanos Forsk) and short-bodied mackerel (Rastrelliger neglectus) with total 90 fish with an
average weight of 99 grams / fish (milk fish) and 85 g / fish (short-bodied mackerel). The fish raw material
purchased from Rejomulyo fish market (Semarang) and taken to the laboratory in a Styrofoam box that was
given ice on the inside. This research used an experimental method called descriptive exploration. Storage
of samples was handled at different temperatures namely 30oC ± 2oC, 15oC ± 2oC and 1oC ± 0oC. The
observed parameters include organoleptic test and analysis of K Value (FTP III). The results showed that K
values for all samples increased during storage at different temperatures. The highest K values of milk fish
and short-bodied mackerel fish during storage at a temperature of 0°C was on 96-hours storage time. The
highest K values of milk fish and short-bodied mackerel fish during storage at a temperature of 15 ° C was
on 72-hours storage time. Whereas the highest K values in milk fish and short-bodied mackerel fish during
storage at 30°C temperatures, was on the 24-hours storage time. The fastest increase in K value was observed at a temperature of 30°C compared to storage at a temperature of 15°C and 0°C for all the fish samples. This means that the deterioration quality of fish will be faster at high temperatures. K values of mackerel increased more rapidly than milk fish.

THE DIRECTION OF FISHERY DEVELOPMENT IN INDONESIA, AND SOME NOTES ON FUNCTIONAL CHANGE OF PEKALONGAN HARBOUR FROM PUBLIC TO FISHERY HARBOUR, 1940-1980
Widodo, Sutejo K.
government policy, fishery harbour, advantages factors.
The Java sea has abundant supplies of fish M various species In the past, along the northern coatl of Java, there were several fish landing centers along the northern coast af Java. The Report of the Commissie van ( Commission of) Mindere Welvaart { report] in 1905 mentioned that the existence of these places was related to the ecology of sea sources. Up to the end cf the colonial government, the policy in fish consumption was based on the import of fish, especially dried and salted fish. The policy was maintained up to the Indonesian era in 1961. Afterwards, fish needs was filled through a policy of sefsrwiciency. This policy was able to support efforts in fishery development. Pekalongan harbour was built in 1852 and opened in 1859 cu a public harbour for export-import Since the earlv Twentieth Century, the function of Pekalongan harbour has declined as a result ofthe modernization of Semarang harbour. In 1974, the Pekalongan harbour was the first harbour to be converted from a trade harbour into a special fishery harbour. The functional change and the development ofthe harbour in the following years are related to the great changes in fishery policy and developments in other areas of 1%.. Pekalongan harbour was tranjormed into one of the most interesting fishery harbours in Java because it has several advantageous factors such as topography, safety guarantee, local sources for informed capital,conducive policy of the central government, geography, and local availability ofmiddle level technology.

A PILOT STUDY FOR THE ESTIMATION OF ABOVE GROUND BIOMASS AND LITTER PRODUCTION IN Rhizophora mucronata DOMINATED MANGROVE ECOSYSTEMS IN THE ISLAND Of MAURITIUS
Abib, Shafiiq
Appadoo, Chandani
Estimation of the above ground biomass of mangroves is an important issue because of its relevance to nutrient turnover and the potential to store carbon. Productivity, as indicated by litter fall rates is important to determine the rate at which mangroves produce new biomass. The aim of the current study was to estimate the above ground biomass and quantify litter fall in two Rhizophora mucronata dominated mangrove ecosystems of Mauritius located at Trou D’eau Douce (eastern side), and at Petite Riviere Noire on the (western side) of the island. Field studies were conducted from September 2011 to January 2012. Quadrats of 5 × 5 metres were set up in each site and 200 mature trees were surveyed. Sixteen litter traps were constructed and installed at the two sites for litter collection. To estimate the above ground biomass, allometric equations were used. The total above ground biomass for Trou D’eau Douce and Petite Riviere Noire were 26.96 t ha-1 and 16.63 t ha-1, respectively. The mean rate of litter fall for Trou D’eau Douce and Petite Riviere Noire were 3.2 ± 0.44 g DW m-2 day-1 and 4.07± 0.95 g DW m-2 day-1, respectively. This study is among the first to provide information on the estimation of above ground biomass for mangroves of Mauritius. It is also the first to provide data on the litter production in mangroves at Petite Riviere Noire and Trou D’eau Douce.

Soft-boned milkfish; traditional food; quality; marketing strategy; Semarang
One of the famous traditional food products from Semarang city is softboned-milkfish (called as bandeng
presto). In national level, Bandeng Presto is the trade mark of Semarang City. Bandeng presto are produced
by several outlet in Semarang from small to large in scales. The products are vary, in term of variety,
quality, processing technique, packaging and prices. The small-scaler produces less in quality standard,
safety, packaging, and marketing system. Nevertheless, there are several small-scaller outlets are able to
reach the international market after they promoted their product through webside or internet. The objectives
of the study were to develop the improved quality in production techniques, lay out designed, and the
marketing strategy for bandeng presto in Semarang city to support the regional food security and food safety.
The results indicated that nutritional content of bandeng presto are good in general and can be considered as
good nutritional resource for human. Raw material and processing technique influence the nutrition value of
the product. Based on market survey suggests that bandeng presto is more efficiently promoted through
website, especially to touch the long distance customers. In addition, improved in packaging design and in
labelling (recently for exposing information on EPA and DHA of the product) will help customers to assure
the quality of the product properly.

EFFECT OF LAND-BASED POLLUTION ON CENTRAL JAVA CORAL REEFS
Edinger, Evan N.
Risk, Michael J.
Land-based pollution has severely damaged nearshore corals reefs in the Jepara area, Central Java. Effect described here include reduced coral cover and diversity, high coral mortality, reduced reef habitat complexity, and increased bioerosion intensity, compared to reference reefs in the Karimunjawa Islands National Marine Park, Central Java. Furthermore, the polluted reefs have negative net carbonate production indicating net reef erosion. Reef health parametres based on coral cover and diversity and on net carbonate production are inversely correlated with chlorophyll A concentration, suggesting eutrophication of coastal waters as a key agent of reef degradation. Untreated sewage dumping, agricultural runoff, and aquacultural effluent all contribute to nearshore eutrophication in Central Java, but it is not possible from this study to determine which of these types of land-based pollution is most responsible for degradation of Central Java reefs. Efforts to restore the condition of degraded reefs must begin with controlling sources of land-based pollution.

Small-pelagic fishery; fishing capacity; data envelopment analysis; Banda sea
Excessive fishing capacity is a core issue in marine capture fisheries. In relation with the capacity issue, this study was conducted to determine annual changes of fishing capacity of the small-pelagic fishery at FMA-714 Banda Sea using time-series data of 1985 until 2006 which was analyzed using data envelopment analysis (DEA) approach. The small-pelagic fishery was found to be excess capacity in 17 out of 22 DMU. And there was indication of overcapacity in the period of 1989 until 1998. The fishery had a tendency to be not efficient with the highest score of 23.7% at DMU-1998. Consequently, alternative fishery management policies are needed to reduce fishing inputs of the fishery at the FMA-714 Banda Sea.

AN EVOLUTION OF PROPERTY RIGHT REGIME OF CORAL REEF MANAGEMENT: FROM AN OPEN ACCESS, TO STATE PROPERTY REGIME AND SUSTAINABLE LOCAL GOVERNANCE - A LESSON FROM GILI INDAH VILLAGE, WEST LOMBOK, INDONESIA
Hidayat, Aceng
Institutional changes, open access, property right regime, coral reef ecosystems, Muroami, local governance
This paper is to explain a case of evolution of property right regime of coral reef management: from an open access to state property and then to local governance, a case study of Gili Indah West Lombok, Indonesia. It demonstrates the reasons of change, the ineffectiveness of state property regime, and the emergence of local governance where conflicts are assumed as the triggering factors. The study found out that conflict of interest between two main stakeholders: tourism business operators (TBOs) and fishermen drove the change process. The conflicts initialLv emerged after Balai Konservasi Sumberdaya Alam (BKSDA) as the executor of the state property regimes was unable to protect the coral reef ecosystems from destructive fishing practice. It has also failed in halting Muroami application that has triggered lasting conflicts between TBOs and fishermen. The failure of the state property regime has led TBOs to take over the protection tasks through constructing local governance. So far, the local governance has been successful in protecting the coral reef resources and forced the users to use the coral reek in a sustainable manner. However, it still shows a number of weaknesses in dealing with new challenges such as the non-involvement of several stakeholders in making social agreements and the unequal distribution of authority and responsibility among the actors and stakeholders. Therefore, attempts to find an alternative regime that could address the new challenges ofthe reef management are still required

Compliance is necessary for successful management of the fisheries. In fact, to secure compliance, enforcement and surveillance, which are quite costly, are needed . It is realized that enforcement inputs in Indonesia is limited and not sufficient to watch the waters of this country. Therefore, it needs a lot of effort to improve the enforcement and surveillance schemes. It is necessary to find out new alternatives or paradigms of monitoring, controlling and surveillance (MCS) in such a way in order to ensure the sustainability of the fisheries resource.

This study focuses on the effect of fallowing of southern blue-fin tuna farms in southern Spencer Gulf, South Australia, on macrobenthic assemblage comparing spatial and temporal patterns of distribution and abundance at eight control sites and eight fallowed pontoon sites, during the period October 2002 to October 2003. Two stations at each site were sampled five times throughout the year with four replicates. Polychaetes were the most abundant organisms both at control sites (76.4%) and fallowed pontoon sites (80.5%). Five dominant taxa (Capitellidae, Cirratullidae, Lumbrineridae, Nephtyidae, and Spionidae), relatively tolerant to organic enrichment, were generally recorded in higher numbers at the fallowed sites than at control sites.Assessed using univariate and multivariate analyses, a significant difference in abundance between the control and fallowed pontoon sites was found, which also showed a significant effect of time. A slight decreased in diversity, number of taxa, and evenness at fallowed pontoon sites compared to those at control sites was observed. Seasonal fluctuations caused by natural variability, especially hydrodynamic conditions and sediment characteristics, are likely to be responsible for the observed changes of the assemblages.

EFFECTS OF SAND MINING ON CORAL REEFS IN RIAU ISLANDS
., Supriharyono
Sand mining, effects on coral reefs
Effects of sand mining on coral reefs have been carried out in Riau Islands, from September to November 2003. The study used was explorative method, while the data were collected both primary through field observation and interview and secondary data obtained from related institutions.
The results showed that the reefs were in moderate to good conditions. Majority of the moderate conditions were found in the deeper water (10 m depth). Similarly, the percentage of living coral cover was also lower in the deeper water compared to the shallow one (3 m). It is believed that this may due to light transparency. However, it is too early to say that the lower of light transparency in the depth 10 m is due to sand mining activities. In addition, the fishing capture production was significantly decreased after sand mining becoming intensive in study sites during autonomy era.

Screening of extracellular chitosanase from bacterial isolates associated with marine sponges have been done. Out of 100 bacterial isolates, forty isolates were capable of forming clearing zones on the chitin media and one isolate, 34-b, produced the highest chitinolytic index. The enzymes was produced on chitin liquid medium at 37oC in a shaking waterbath for a five-day cultivation. Crude enzymes were prepared by cell-free supernatant (CFS) and concentrated through 70% (saturated) ammonium sulphate percipitation followed by dialysis. The enzymes worked best at pH and temperature of 6-7 and 60oC, respectively. The half-life (T1/2) for chitosanase activity was 500.2 min or 8.34 hours (at 37oC) and 55.12 min (at 50oC), indicating the enzyme are quite stable at that temperature. However, around 80% of the original activity was lost at 60oC after 15 min of incubation.

Heavy metal pollution, metal speciation, sediment, Dumai
Heavy metal concentrations in sediment collected from Dumai coastal waters have been studied by using sequential extraction technique to determine the distribution and geochemical speciation (EFLE, acid reducible, oxidisable organic and resistant) of Cd, Cu and Ni. The results showed that the highest concentrations of total Cd was in Cargo Port area and the lowest in Penyembal, whilst for Cu and Ni the highest concentrations were in Ferry Port and the lowest in Batu Panjang. The total concentrations of Cd, Cu and Ni ranged from 0.65 – 1.82, 1.84 – 13.16 and 7.68 – 17.98 µg/g dry weight, respectively. Higher metal concentrations were detected in the eastern and central parts of Dumai city center where most of anthropogenic activities are concentrated. However, most of the concentrations of Cd, Cu and Ni were still below the ERL and ERM values. Only at few stations, especially in the eastern and central parts of Dumai, showed Cd concentrations exceed the ERL but still well below the ERM values. Metal concentrations in 78.26% (Cd) and 91.30% (Cu and Ni) of the sampling stations were dominated by resistant fraction indicating natural origin of these metals. Non resistant fractions, however, were found higher than resistant fractions at Pelintung, Pertamina, Cargo Port, Penyembal and Batu Panjang for Cd; Penyembal and Batu Panjang for Cu and Pelintung and Guntung for Ni. These findings indicated that anthropogenic inputs of Cd, Cu and Ni occurred in these stations. For all sampling site groups, Cd, Cu and Ni were mostly accumulated in the resistant fraction (55.28 – 58.31%; 65.02 – 91.84% and 50.08 – 66.88% of the total concentrations respectively) which indicated that the mobility and anthropogenic inputs of these metals in Dumai coastal waters were quite low.

Environmental extremes ; life history ; Montipora digitata ; tolerance
Intertidal zone in reef flat is the extreme condition for many species of corals. Periodical tides, wave action and sedimentation become the main challenging factors which usually avoided by most of coral species. However, Montipora digitata is the species that found abundant in these conditions. Having relatively small and short-lived colony, forced this species to find the strategy to survive and maintain the energy efficiently. Understanding biology and life history of M. digitata in the coral reefs is the key to understanding how this species can adapt to the extreme conditions. The biology and life history of this study focused on the population size structure, reproduction, competitive interactions, investment repair and maintain and types of selection. M. digitata leaded to productivity as a strategy to cope with any extreme condition. This pattern relatively matched with r-and S-R selection.

Zooxanthellae, Symbiodinium sp, are single cell dinoflagellate algae known to live in association with many marine invertebrates such as hermatypic corals, sea anemones, jellyfish and giant clams (family Tridacnidae). In giant clams, these photosynthetic algae are located in a tubular system (known as Z tube system) which occurs within the clams. Apart from filter feeding, the nutrition of the clams is provided by zooxanthellae. These algae are capable of translocating part of their photosynthetic products to the host. CZAR values are also discussed.

Organochlorine pesticide; Banten Bay; persistent organic pollutant
Studies on distribution of organochlorine pesticides in water column and sediments from Banten Bay were conducted during transitional season on April and October, 2001. The objectives of the study were to determine the concentration and distribution of total organochlorine pesticides in water column and sediments in transitional seasons, and to identify its sources. Our study showed the concentration of pesticides organochlorine in water column ranged between 0.366 and 4.391 ng/l with an average of 1.952 ng/l in April (location 1), and 0.357 and 2.998 ng/l with an average of 1.203 ng/l in October (location 2). And then pesticide concentration in sediment were ranged between 0.263 and 2.090 µg/l dry weight (dw) with an average of 1.281 µg/l in June (location 1), and 0.068 to 10.095 µg/l dw with an average of 1.775 µg/l in October (location 2). The result indicated different influence of the season on organochlorine pesticides concentration and there was fresh input of DDT in the study area.

STATUS OF MANGROVES IN SRI LANKA
Karunathilake, K. M. B. C.
Institute of Fundamental Studies, Hantana Road, Kandy http://www.coastdev.undip.ac.id
Array
In Sri Lanka many estuaries and lagoons are fringed with vastly diverse mangrove forests. The total mangrove cover is very small as 0.1 to 0.2 percent of the total land area. The distribution of fauna and flora varies along with wet and dry zone in the country. Around 25 species of flora are exclusive to mangroves and more than 25 species can be identified as associated mangroves. Variety of invertebrates and vertebrates are conspicuous in the mangrove forests, but only a few species are confined to the ecosystem. Heavy utilization and reforestation for shrimp farms and building construction work severely affect on this ecosystem. When compare to decline rate of mangrove forests in Sri Lanka, current implemented conservation measures are inadequate.

STUDY TO INVESTIGATE INDUCED SPAWING METHOD AND LARVAL REARING OF THE SEA CUCUMBER Holothuria scabra *)
Hartati, Retno
Pringgenies, Delianis
Sea cucumber , induced spawning, larvae
In irder to increase natural population stocks, a sea cucumber cultivation project was attempted in the Karimunjawa Islands (Java Sea, Indonesia). Since continuous production of larvae is essential to such a project, this portion of the research focuses on methods of inducing the sea cucumber Holothuria scabra to spawn and monitoring the development of resulting larvae. Four different types of environmental manipulation were used to try and induce spawning; artificial fertilization (using manually extracted eggs and sperm), thermal shock (raising the temperature of the spawning medium), desiccation (partially drying out) and treatment with potassium chloride (KCL) solutions of various concentrations. The development of the resulting larvae was carefully observed.
Results indicate that thermal shock, desiccation and potassium chloride (KCL) are all effective in stimulating the sea cucumber Holothuria nobilis to spawn. Thermal shock gave the best result with both male and female spawning and 90% larvae development. Using a stocking density of 300 larvae/ liter in 10 liter aquaria, larvae was successfully raised up to pentactula stage. Regardless of the method used to induce spawning, fertilizer eggs development into auricularia larvae at 31 hours and 30 minutes. These larvae then metamorphosed into doliolaria and pentactula larvae at day 13 and 26. Mortality of all stocks at the pentactula stage was probably due to lack of provision of settlement substance.

APPLICATION OF BIOAUGMENTATION TO SOLVE AMMONIA IN THE SEDIMENT OF THE CULTURE MEDIUM OF TIGER SHRIMP (Penaeus monodon F.) IN DIFFERENT SALINITIES
Sarjito, S.
Bioaugmentation, Ammonia, Epicin, Sediment, Salinity
Bioaugmentation was used to solve the ammonia problem, because this method is relatively safe to the
environment. The objective of this research was to determine the influence and effectiveness of
bioaugmentation on the reduction of ammonia in the sediment in culture medium of Tiger shrimp (P.
monodon). Laboratory scale experiment and splitted plot randomized design was performed. The main
treatment was probiotic epicin concentration of 0; 0.5; 1.0; and 1 ppm; as sub-treatment was the salinity
(20; 25 and 30 ppt), and as a group was dayobservation (0; 2; 4 and 6). Sediment from intensive culture
system was taken from brackish water pond of Brackishwater Aquaculture Development Project (BADP),
Jepara. Sediment ammonia was analyzed using methods of Parson et al.,(1989). The research was conducted at hatchery of Fisheries and Marine Science Faculty of Diponegoro University, Teluk Awur, Jepara. The result indicated that bioaugmentation was able to reduce ammonia concentration in the sediment. Epicin has high significantly effected on the reduction of ammonia in the sediment (p<0.01). The
capability of epicin as a bioaugmentation started on the day of 2. Therefore, the results also showed that a time (day) was highly significant affect on the reduction of ammonia in the sediment (p<0.01). However, salinity did not affect on the reduction of ammonia in the sediment (p>0.05). The most effective epicin dose to reduce ammonia in the sediment of the culture medium of Tiger shrimp (P. monodon) was 1.5 ppm.

Sudaryono, Agung
Fish silage; Marine feedstuffs; n-3 fatty acid; PUFA; EPA; DHA
This study was designed to evaluate fish silage made from various marine feedstuffs (shrimp head, blue crab waste, mud crab waste, squid and tigawaja trash fish) as potential sources of n-3 fatty acids for aquaculture feeds. The marine feedstuffs and the fish silage were analysed for fatty acids contents. Results of fatty acid analysis showed that all the fish silage had higher levels of PUFA (polyunsaturated fatty acid) of linolenic acid (LNA; 18:3n-3) and HUFA (highly unsaturated fatty acid) of eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) than the feedstuffs. This study indicates that the bioactive substances contents of n-3 fatty acids (LNA, EPA, DHA) in squid can be significantly improved by manufacturing the fish silage. Fish silage from squid was found to be the most potential source for PUFA (LNA; 5.08 vs 10.72) and HUFA (EPA; 8.07 vs 17.50 and DHA; 7.18 vs 18.08 g/100 g lipid) among the others and suitable for aquaculture feeds.

Takarina, Noverita Dian
geochemical fractionation, heavy metals, estuary, sediments, Jakarta Bay
Jakarta Bay is located at the north coast of Jakarta bordered by 106 03'00'' Longitude and 6 10'30'' Latitude. Administratively bordered by Bekasi Regency on the east and Tangerang Regency on the west. There are 13 -19 rivers flow to the bay with 2050 industries that produce hazardous waste, including heavy metals. Metal concentrations in surface sediments and their spatial distributions have increased, recently. Concentration of Pb during 10 years period increase from 23.3 mg kg-1 to 118.2 mg kg-1. The objectives of this study is to know the distribution of Chromium (Cr), Copper (Cu), Lead (Pb), and Zinc (Zn) of Jakarta Bay, Indonesia and their geochemical partition in marine sediments that are bound to “Exchangeable Fraction”, “Reducible Fraction”, “Fe-Mn Oxide Fraction”, “Oxidize able Fraction”, and “Residual Fraction”. The result showed that the concentration of heavy metals in the sediments in most locations were above the Canadian Standard for Contaminated sediments. Concentration of Cr ranged from 48.68—292.09 ppm, Cu ranged between 18.62—151.82 ppm, Pb ranged from 39.7—303.42 ppm, and Zn ranged between 165.83—487.69 ppm. Standard for Cr, Cu, Pb, and Zn are 22 ppm, 30 ppm, 25 ppm, and 60 ppm, respectively. Percent fraction of Cr in labile fraction (F1, F2, and F3) ranged from 30-60 %, while for Cu, its percent fraction mostly bound to lithogenic fraction as much as 38–78%. Percent of labile fraction of Pb ranged from 22-54 %, while for Zn as much as 15-72%. These meant that not only Cr but also Pb and Zn were possible to be easily released in the environment as bioavailable metals for biota, especially, benthic invertebrates.

THE DEVELOPMENT OF SELECTIVE AND UNSELECTIVE FISHING GEAR OWNED BY FISHERMAN AT THE NORTH COAST OF CENTRAL JAVA
., Asriyanto
Setiarto, Agung
North Coast of Central Java (Indonesia), Fishing Gear, Development 1993-1997
Introduction : The Utilization of fisheries resource in Indonesia waters has just achieved about half (56.06%) of the maximum sustainable yield. In the north coast of Central Java, which has a coastal line of about 450 kilometers, 20 types of fishing gear are owned by fishermen.
Experiment : Data were collected from Annual Report 1993 – 1997 issued by Central Java Fisheries Agency. Twenty types of fishing gear were classified into 6 groups, i.e. seine nets, purse seine, gillnets and trammel nets, lift nets, lines, and traps. Two of them were categorized as unselective fishing gear, i.e. seine nets and purse seine, whereas the other 4 were classified as selective ones. The number of each group was expressed in means and percentages and the development/changes thereof was presented in percentage.
Results and discussion : The number of unselective fishing gears grew rapidly from 1996 to 1997, i.e. seine nets 17.31% and purse seine 12.07%. on the country the number of selective fishing gear increased slightly or even decreased, for example traps (5.98%), line (4.13%), liftnets (-3.21%), and gill nets & trammel nets (-2.45%). The management of fisheries resources should be focused on the enhancement in the number of selective fishing gear and the extension of their fishing ground, combined with close monitoring on the mesh size of unselective fishing gear.

Determination of bioaccumulation factor of mercury (200Hg) in chanos chanos of Semarang municipality fishponds has been carried out by applying the neutron activation analysis (NAA) and gamma spectrometry analysis. The gamma spectrometry technique was employed to analyze the gamma radiation exposure from activated samples. The heavy metal 200 Hg can be identified in water and milk fish (Chanos chanos), along with natural radionuclides 40K in water. The concentration of Mercury in the water at the 3 villages was 0.950 10-6 ppm, 284 10-6, and 350 10-6 ppm respectively. Whilst mercury concentration in the milk fish was 186 10-3, 068 10-3, and 098 10-3 ppm for Mangunharjo, Mangkang, dan Karanganyar respectively. Bioaccumulation factor can be estimated from the ratio of these heavy metal element in the sample and the water. Result shows that the bioaccumulation factor for mercury at 3 villages (Mangunharjo, Mangkang dan Karanganyar) is 195.942, 238.961, 279.614 respectively.

THE EFFECT OF CHITIN AND CHITOSAN OF CRAB SHELL ON WATER SORPTION OF ISOTHERM AND DENATURATION OF MYOFIBRILS DURING DEHYDRATION PROCESS
Darmanto, Y. S.
Chitin, chitosan, monolayer water, multilayer water, myofibrils protein, and Ca-ATPase
Indonesian shrimp production is estimated at approximately 342,000 tons per year, followed by crab production at the level of more than 200,000 tons annually. Apparently, 50 – 60% out of the total production consists of waste in the form of crab shell. Crab shell is rich in chitin, chitosan, and cellulose. The United States, Japan and other developed industrial countries have used chitin, chitosan, and cellulose as raw material for various purposes, such as toxic waste processing, water purification, enzyme immobilization, skin and hair cosmetics, bone connecting, biomedicine, paper and textile industry, pharmacology, film, food industry, feed and others Chitin (C8H13NO5) is a Poly-b-N-Acetyl-D-GlucoSamine standing for a natural biopolymer, which constructs the shells of crab species. Chitin cannot be examined as a pure essence, since it is melt with rich texture of protein, CaCO3, fat pigmen, and small amount of metals. In order to fabricate Chitosan, one should demolish the Acetyl cluster of Chitin by employing strong alkalis. Chitin makes up the combination between Poly (N-acetyl-2-amino-2-deoxy-b-D-gluco-piranosa) and N-acetyl-2-amino-2-deoxy-D-glucopiranosa. To find out the effect of chitin and chitosan from crab shell on the water sorption isotherm of myofibrils protein during dehydration process, chitin and chitosan from crab shell were added to myofibrils protein at the ratio of ratio 2,5 – 7,5 g / 100 g, homogenized, and afterwards dried in a dessicator. After some time, moisture content, water activity (Aw), Ca-ATPase activity, and proximate were analyzed. Mono layer water was analyzed according to Brunauer’s method (1968), multi-layer water was analyzed according to Bull’s method (1944), whereas Ca-ATPase activity was analyzed using the formula introduced by Katoh et. al. (1977). The result of the analyses shows that a higher concentration of chitin and chitosan on myofibrils resulted in higher amount of mono-layer and multi-layer water. The presence of different amount of mono-layer and multi-layer water indicates that the state of water changing occurs on myofibrils protein which in turn affects its quality. Likewise, the increase of chitin and chitosan concentration suppresses the decrease of acceleration of Ca-ATPase activity.

Lupinus angustifolius, Penaeus monodon, lupin meal, feed cost efficiency
A comparison of the cost efficiency of the formulated diets for juvenile Penaeus monodon in which fish meal or fish meal and soybean meal mixture were substituted with lupin (Lupinus angustifolius) meal at different levels has been conducted and is described in this study. The method used in the study was to estimate the relative economic performance for each dietary treatment using cost efficiency analysis equations. All diets containing different levels of lupin meal (0-30% and 0-48%) were compared in terms of total feed cost to determine the most cost-effective lupin meal based diet for juvenile Penaeus monodon reared in pens under pond conditions. The results show that inclusion of lupin meal at a level of 30% that substitute 75% of fish meal protein in D4 formulation saved 18% in price in Australia and 11% in price in Indonesia when compared with D1 with no lupin meal. Diet D9 including 48% of lupin meal to substitute 75% of a mixture of fish meal and soybean meal saved 21% in price in Australia and 14% in price in Indonesia when compared with D6 with no lupin meal. it is concluded that diets D4 and D9 containing 30% and 48% dehulled lupin (L. angustifolius) meal as a replacement of 75% protein of fish meal and the mixture of fish meal and soybean meal, respectively can be considered as the most economical and profitable diets with an acceptable level of production for semi-intensive pond culture of P. monodon stocked at a level of 10 animals/m2.

CORAL REEF MANAGEMENT IN PADAIDO MARINE TOURISM PARK, BIAK NUMFOR Case Study for The Alternative Solution to Destructive Fishing Practices on Coral Reefs
., Supriharyono
Coral reefs management, Destructive Fishing
Coral reef is the most productive marine ecosystem in coastal waters. Unfortunately, this ecosystem has already suffered from non-sustainable human use including destructive fishing practices (bombing and cyanide), coral mining, over fishing, settlement pollution and uncontrolled tourism development. These affected the production of those fisheries resources in coral reefs. In order to manage those resources, such alternative to destructive use need to be studied.
This paper reports alternative solution to destructive fishing practices on coral reefs. The study has been carried out at Padaido Marine Tourism Park, the District of Biak Numfor, West Papua province, for about 2 weeks, 9-18 June 2001. Survey method was used during the study. The data were collected using Participatory Rapid Appraisal (PRA)’s method, with members of fisher group as the participants.
Three kinds of reef fish groups are identified at the Padaido Islands waters, i.e. major group, target group, and indicator group. These include ornamental and consumption fishes. Fish were caught with several fishing gears; while some of them are identified as destructive fishing practices, e.g. bomb, cyanide fishing. However, some of them can be recommended as sustainable fishing technologies, i.e. (1) squid jig, (2) troll line, and (3) hand line.

The use of chitosan as preservative agent in fish processing had been conducted for some reasons for example its usage as food additive that can prevent microbial growth, as antioxidative agent, and, to some extent to produce safe food. This research studied the application of chitosan on salted-dried anchovy (S. heterolobus) preservation during storage at room temperature.
The aims of this research were to know the effect of treatment (chitosan concentration and storage time) on the quality of salted-dried anchovy (bacterial count and organoleptic test). The experimental design used was Split plot in time design and using Randomized Complete Block with two factors. The first factor was chitosan concentrations (0,0%; 0,5%; 1,0%) while the second factor storage time (0; 2; 4; 6; 8 weeks).
The results indicated that chitosan concentration and storage time significantly reduced the total bacterial count (p<0,01) but not significantly different (p>0,05) for organoleptic test. The interaction of chitosan concentration and storage time significantly influenced the total bacterial count (p<0,01).

Coral reef; remote sensing; ALOS imagery; Natuna islands
The coral reef ecology of the Natuna Islands has been studied over 10 years. However, none of those studies produced a coral reef map. Maps of coral reef ecosystem are important for planning, management and monitoring tool. The present study integrates the 115 field data and the ALOS satellite data, using depth invariant index algorithm to generate coral reef ecosystem classes. Those classes are: life corals, dead coral and rubble aggregates, mixing of substrates and sand. The algorithm that composed of three visible bands is applicable at clear water rather than at turbid water environment. Hence, vegetation coverage as well as seagrass, seaweed and macro algae which are in small extent and usually covered by fine sand materials and associated with turbid water, cannot be classified.The aim of this research, which is funded by Critic Coremap – LIPI, is to produce map of coral reef ecosystem in the Natuna Islands.

THE CONDITION OF PLYWOOD INDUSTRIAL WORKERS : A CASE STUDY IN SUMBEREJO, CENTRAL JAVA
Kistanto, Nurdien H.
transformation, labour, industry, agriculture
Java is often seen as epitomizing a subsistence farming economy, but since the establishment of sugar factories in the first half of the nineteenth century Javanese villages have been familiar with the notion of factory work and factory workers.
As a result of establishment of many large-scale factories in the 1970s, the industrial workforce in java has grown rapidly. These factories from part of the large-scale modern manufacturing and processing sector of the economy which is expected to absorb more manpower as the Indonesian economy is transformed with the enlargement of its industrial base. As a consequence of increasing population in rural Java, structural changes will continue: agriculture will continue to decline, while manufacturing, trade and services will have to play an increasingly important role in absorbing new entrants into the workforce. Limitations on employment in agriculture force people to join the manufacturing workforce : labour will be “pushed” into manufacturing, trade and service, rather than “pulled” out of agriculture (to use White’s description). In Sumberejo, the industrialized village under study, the implications of such a view can be seen in the context of absorption of new entrants into the plywood manufacturing workface.
Based on a field research, it goes to the analysis of conditions of industrial worker in the rural village where the plywood factory has been established since the late 1970s. one indication is clear that an ongoing process of diversification of rural-farm occupational opportunities has been taking place; it is also obvious that there is a considerable decrease in rural farm occupational opportunities. Moreover, increasing pressure on land, both fragmentation through inheritance and alteration for industry, has forced a growing number of villages, particularly the younger and more educated but landless, to seek employment off the farm, which is in Sumberejo in the form of plywood manufacturing workforce.
The field survey and observation reveal that a considerable number of plywood factory worker, or their household members, in Sumberejo seek additional income for their households. Those who seek other incomes are not only they who earn a smaller income form the factory; some non-staff members of the factory with comparatively larger industrial income, and/or their wives and other household members, have additional incomes from non-industrial activities, such as farming and trading. Without additional incomes from other activities, many of them can hardly improve their modest lives.

COMPARATIVE SELECTIVITY AND CATCHABILTY OF POT AND TUBE FOR CONGER EEL (Conger Myriaster)
Iskandar, Dahri
Selectivity ; catchability ; tube ; pot ; conger eel
The objective of this experiment was to develop a method to estimate mesh selectivity of pot and comparative catchability between pot and tube for white spotted conger eel (Conger Myriaster). About ten times comparative fishing experiments were carried out off Haneda in Tokyo Bay, during October and November every year from 1997 to 2000. The experiment used collapsible pots of 5 mesh openings (21.0, 18.1, 15.5, 13.6 and 11.6 mm) and tube of 9.06 mm hole diameter as control gear. Result of this experiment indicated that pot of larger mesh size caught larger conger. Significant different was found in length distributions between the four years (ANOVA Test, P=1.9x10-45) and then the data were not combined for the analysis. In term of girth-perimeter ratio, R value of 50% retention and selection range were calculated to be 1.19 and 0.24 from estimated logistic parameters, (α,β)=(-10.67, 8.99). When catchability of tube was assumed to be 1, relative catchability of pot with 21.0, 18.1, 15.5, 13.6 and 11.6 mm mesh openings were 0.62, 0.79, 0.73, 0.63 and 0.51, respectively. This suggested that one tube could catch more conger eel than one pot and pot of larger mesh size was likely to catch of larger size more effectively.

ANTIBACTERIAL ACTIVITY OF BACTERIAL SYMBIONTS OF SOFTCORAL Sinularia sp. AGAINST PATHOGENIC RESISTANT BACTERIA
Sulistiyani, S
Antibacterial activity, softcoral, Sinularia sp., bacterial symbionts
Infections caused by resistant microbes may cause failure to respond to medical treatments, resulting in prolonged illness and greater risk of death. Treatment failures also lead to longer periods of infection, which increase the numbers of infected people moving into the community and thus expose the general population to the risk of contracting a resistant strain of infection. Soft corals have been known to produce secondary metabolites, some of which may have anticancer, antifouling, antibacterial activity. It has been suggested that natural products from marine invertebrates have striking similarities to metabolites of their association microorganisms. The aim of this study was to isolate and characterize bacterial symbionts of soft coral Sinularia sp. having antibacterial activity against pathogenic Multi Drugs Resistant bacteria (Staphylococcus aureus, Escherichia coli, and Enterobacter). Five were successfully screened for antibacterial against resistant pathogenic bacteria. Two isolates, SNTGZ10 and SNTGZ11 were found to inhibit the growth of MDR Staphylococcus aureus, SC4TGZ3 and SC4TGZ11 inhibited the growth of MDR Escherichia coli and Enterobacter sp. , while isolate SC4TGZ4 inhibit the growth of MDR Enterobacter sp. Molecular identification revealed that: SNTGZ10 and SNTGZ11 were closely related to Virgibacillus; SC4TGZ3 to Pseudovibrio; SC4TGZ4 to Alphaproteobacteria; and SC4TGZ11was closely related to Microbulbife. The bacterial symbionts of softcoral Sinularia sp. offer potential source of antibacterial compounds in particular against MDR strains.

THE BIOLOGY OF SPINELESS CUTTLEFISH Sepiella inermis d’Orbigny IN THE NORT COASTAL WATER OF JAVA
Ghofar, Abdul
cuttlebone, tentacular clubs, lower beaks, hood length
A study was carried out to investigate the length-weight relationship, reproductive aspect, growth, and the relationship between beaks and body size of the spineless cuttlefish, Sepiella inermis d’Orbigny in the north coastal water of Java. The length-weight relationship varies relation to sexes; the slopes (b) are 2.147 for male and 2.436 for female, implying that the female attains a larger size at the same length. The fecundity of the species ranges from 145 to 225 eggs (taken by means of direct egg counting from individual having mantle length of 73-92 mm). The length at first maturity was estimate to be smaller in the male (73.24 mm) than in the female (91.63 mm). A growth model of the species is derived, based upon the data cuttlebone striations and mantle length. The life span of the species is estimated to be around 1 year, with a maximum mantle length of about 140 mm. The species grows rapidly, with curvature parameter of 2.413 yr1, and a hypothetical age t0 of -0.01 yr1. Lower hood length of the beaks show a strong, positive linear and exponential relationships respectively with mantle length and total body weight. Their potential use for biomass estimation, and for tropho-dynamic studies in the coastal water are indicated.

The flow water velocity is closely correlated to oxygen demand. Oxygen plays an important role as the indicator of fish blood. The objective of research is to acknowledge red blood cell, hematocrit, hemoglobin, and white blood cell of grouper larvae given with flow water velocity treatments. Research begans from June 2011 to September 2011 at Lampung Marine Aquaculture Center. Juvenile with 7-9 cm length and 15-17 g/fish weight were tested using complete random design with three treatments of flow water velocity, i.e. 1.25 m/sec (A), 1.00 m/sec (B), and 0.75 m/sec and control treatment. All treatments had 3 replications. Result of research indicates that flow water velocity had obvious effect on red blood cell, hematocrit, hemoglobin, and white blood cell. Red blood cell total was the highest in treatment of 1.25 m/second, counted for 2,922,666 cells/ml. It was followed by treatment B with 2,816,000 cell/ml, treatment C with 2,763,000 cell/ml and control with 2,573,333 cell/ml. The highest hemoglobin was found in treatment A, followed by B, C, and control treatments. The highest hematocrit rate was seen in treatment A, followed by B, C and control treatments. The highest white blood cell total was discovered in control, followed by C, B and A treatments.

Study on ecological energetics of tropical limpet C. testudinaria has been carried out at approximately
one year from October 2001 to September 2002. Population energy budgets estimated on the
assumption of steady state conditions for C. testudinaria (Linnaeus, 1758) on the rocky shore of
Ohoiwait, are presented. Large difference in population structure, and hence energetics, occurred at
different localities along the rocky shore. Relatively high proportions (98 %) of the assimilated energy
was lost via metabolism. Assimilation efficiency is 39 %, net growth efficiency is 1.8 %, and ecological
efficiency 0.3 %. Production (P), energy flow (A) and total energy consumption (C) were expressed as
functions of animal size, in order to facilitate gross estimations of the energy component for which data
on size frequency and density are available.

GIS-ASSISTED COASTAL ZONE PLANNING
Rooseboom, Hans J.B.
In this paper we opine that a geographic information system can provide essential and much needed support to integrate coastal and marine resource management, provided, however, that a number of preconditions have been met.
Detailed and highly accurate geo-referenced digital data are available to the coastal zone manager. If required, sub meter accuracy can be introduced into the planning process. We would, however, like to propound that the most effective mapping scale for integrated coastal and marine resource management (in Indonesia) is 1:250.000, which would hardly warrant sub-meter accuracy.
The necessity to include the motivations and activities of multitude of stakeholders further diminishes the need for detailed and sophisticated systems, as their disorderly, random and often haphazard behavior defies attempts at accurate modeling.
We therefore believe that GIS for coastal resource management is best used as a system to monitor events, and to interpret the results there through querying the database by way of algorithmic as well as visual methods and techniques. The resulting information should then be presented as an easily accessible and friendly decision support tool to the coastal zone managers.
A GIS, in other world, should be a management support tool, not a device to spout answers (decisions) derived from mathematical calculations performed on a “model” of the marine and coastal zone.
By designing the system to monitor events and change at scale of 1:250.000, the managers would be forced to concentrate on the main trends and developments, and see the coastal zone in its relation to its wider surroundings. They would moreover avoid the collection and loading of superfluous details, which generally result in data-overload and system slow-downs, if not failures. And most importantly, a manager would be forced to use his creativity and imagination in guiding, directing and cotrolling the utilization of marine and coastal resources

THE PERFORMANCE OF LUPIN MEAL AS AN ALTERNATIVE TO FISHMEAL IN DIET OF JUVENILE PENAEUS MONODON UNDER POND CONDITIONS
Sudaryono, Agung
Lupinus angustifolius; Lupinus albus; fishmeal replacement; Penaeus monodon; pond culture
The present study was designed to investigate the performance of isonitrogenous practical diets containing different inclusion levels of dehulled lupin (Lupinus angustifolius) meal as an alternative for fish meal for juvenile Penaeus monodon (4.32 ± 0.57 g) reared in pens under pond conditions with a natural productivity. Five isonitrogenous experimental diets were formulated to contain 0, 10, 20, and 30% dehulled lupin (L. angustifolius) meal with a corresponding reduction in fish meal from 24 (0% replacement; D1 as control) to 18 (25% replacement; D2), 12 (50% replacement; D3) and 6% (75% replacement; D4) and a diet containing dehulled lupin (L. albus) meal formulated to be similar to D2 which was designated as D5 and used for comparison. Each treatment was tested in quadruplicate and arranged in a completely randomised design. In addition, a group of shrimp put in four pond pens was not fed, to estimate the contribution of pond natural production to shrimp growth.
There was no significant effect (P>0.05) of different dietary treatments on mean individual weight gain (13.3-14.2 g), survival rate (88-93%) of shrimp, and feed conversion ratio (1.45-1.55). The presence of natural food in the pond was important to boost shrimp production and approximately 36-67% of growth of shrimp in the present study was supplied by natural food. Under such conditions, dehulled lupin (L. angustifolius) meal can replace up to 75% of protein from fish meal at inclusion levels of up to 30% in isonitrogenous practical diets without any adverse effects on growth, survival, and feed conversion ratio of juvenile P. monodon. Although this study was performed using a pond pen model on a small scale, the results obtained have provided useful information on the potential of lupin based meals in a commercial semi-intensive shrimp farming.

This study examines the settlement behaviour of the mytilids Mytilus galloprovincialis, Brachidontes erosus, Brachidontes rostratus, and Trichomya hirsutus larvae in response to different substrata: which were byssus threads of these four mussel species, coconut thread, and Polyvinyl chloride (PVC). The number of settlers on different substrata in the laboratory was analysed separately for each species using One-way ANOVA. A significant effect of substratum was found for all species tested. Larvae of T. hirsutus and B. erosus settled preferentially on conspecific byssus threads, while B. rostratus and M. galloprovincialis showed a similar trend. Settlement data from the field was analysed using two-way ANOVA with species and substrata as the main effect. Settlement was effected by species, but not by substrata. However, the overall settlement pattern indicated a conspecific preference with the lowest number of settlers on PVC substratum. Small size of settlement larvae of B erosus comparing to settlement larvae of T hirsutus, M galloprovinciallis, and B rostratus was observed.

Grouping of 78 psychrotrophic bacteria isolated from surface and deep-sea waters of the north-western Pacific Ocean was carried out by RFLP analysis on the basis of PCR-amplified 16S rDNA. Six RFLP patterns from surface water and eight RFLP patterns from deep-sea water were obtained by HhaI digestion. F pattern was only found in the surface water, while g, h, and I patterns exclusively exited in the deep-sea water. It was clearly shown that RFLP patterns of HhaI digestion were clear and distinguishable. This method is very simple and promises a rapid tool to group numerous isolated from natural environments.

The most influencing area on the preservation of the coastal environment is mangrove forest. Mangrove ecosystem is interface between land and sea ecosystem, thus this ecosystem possesses specific function in that its continuity depends on dynamics occurred in the land and sea ecosystem. Mangrove ecosystem is one of several ecosystems in that it has high productivity that produces food resource for most of shore biota. Besides, from fishery side, mangrove also possesses role as spawning and nursery grounds. Nevertheless, the condition of mangrove in Indonesia is experiencing damage and width shortening. To hold the degradation speed of mangrove forest, one appropriate effort could be silvofishery. Silvofishery in an integrated activity between brackish water fishery and mangrove forest cultivation at the same location.

SHRIMP CULTURE OF Penaeus monodon WITH ZERO WATER EXCHANGE MODEL (ZWEM) USING MOLASSES
Panjaitan, Pohan
Inorganic nitrogen; heterotrophic bacteria; zero water exchange model; molasses; C:N ratio level
One of the main obstacles to develop an intensive aquaculture is the accumulation of toxic inorganic nitrogen
which should be kept very low by frequent water exchange or recycling of the water through a biofilter.
This study describes another method of removing inorganic nitrogen using heterotrophic bacteria population
of which was augmented by the addition of a carbonaceous substance, molasses, to increase the feed C:N
ratio under laboratory condition. The principal aim of study was to establish correlation C:N ratio level
with levels of ammonia, nitrite, dissolved oxygen, pH and shrimp growth in Penaeus monodon shrimp
culture with Zero Water Exchange Model (ZWEM) using molasses as carbon resource. It was found that
addition of molasses to shrimp farming with ZWEM had a role in removing ammonia and nitrite. Also,
application of molasses to laboratory tanks increased the growth and percentage weight gain of shrimps and
increased the population of heterotrophic bacteria.

STUDY ON SEDIMENTOLOGY FROM THE MESJID RIVER ESTUARY AND ITS ENVIRONS IN THE RUPAT STRAIT, THE EAST COAST OF SUMATERA ISLAND
., Rifardi
Sedimentology, coastal management, sediment characteristics, abrasion
The sedimentological aspects of the Mesjid River Estuary and its neighboring seas are revealed by various analytical approaches; i.e. mechanical grain size analysis, ignition loss method, metallic element analysis and sand grain composition analysis.
The estuary area is characterized by fine sediments (very fine sand to very fine silt). Based on the relation between the character of bottom sediments and the environmental condition, the the Mesjid River Estuary and its Environs is divided into the following three areas: 1) The western part of the study area characterized by rather coarse-grained sediments and low mud content under the influence of longshore current and poorly sorted sediments supplied by the Mesjid River, 2) The southern part of the study area characterized by coarse-grained sediments under the influence of strong tidal currents, 3) The northern and eastern parts of the study area characterized by fine-grained sediments and high mud content under conditions of sea water masses. The texture and organic matter content of the sediments play important role on the growth of the mangrove which thrive along the coast of the study area.

The adsorption process of metal ion to algal sudace groups and complexes to become organic material at all growth phases could be ajecting their behaviour in seawater. The dwerential pulse anodic stripping voltammetry (DPASIO method was used to determine the adsorption and interaction between the Dunaliella salina and Pbz`. The rate of adsorption was found in two steps; first a relative fast adsorption step (I0 min) and second slower or aw'usion—controlled uptake into the cells. The parabolic equation could be performed ([Pb2+]mr,a = L3 I x I0'7 + 0.062 x 107 V0 to describe the relationship between metal ion adsorption and uptake by the algae as a function of time. The high ajfinity constant is similar to the complexing capacity by the alga and no signylcant effect of cell density on binding capacity. This shows that ligands produced by the algae play an important part in buffering concentration of free metal concentration

BUREAUCRATIC SUPPORT-RELATED FACTORS AND THEIR RELATIONSHIPS TO THE IMPLEMENTATION OF A DECENTRALISED FISHERIES EXTENSION IN JAVA, INDONESIA
., Waridin
decentralisation policy, fisheries extension, bureaucratic support factors, effectiveness, implementation
This study is aimed to assess the relationships between bureaucratic support-related factors and the implementation of decentralisation policy in fisheries extension. Population of this study comprised fisheries extension officers (FEOs) at the Rural Extension Centres (RECs) in Java, Indonesia. A multi-stage random sampling method was used for selecting the subjects of the study. A total of 50 FEOs at 10 districts in three provinces were covered. Data were collected from January to March 1998 by using interview and self-administered techniques. Descriptive statistics and correlation analyses were applied.
Decentralisation policy in fisheries extension was not effectively implemented at the local level. Effectiveness in programme planning, decision-making, resources utilisation, and provision of benefits were not implemented as expected by the policy objectives. As beneficiaries of services, fishers received little from the implementation of decentralised fisheries extension. The effectiveness of the policy implementation was positively and significantly correlated to the bureaucratic support-related factors, which comprised of support from district government bureaucracy and supervision as well as guidance from related agencies.

Azolla pinnata meal; soybean meal; Penaeus monodon; practical diets; juvenile
A 42-day feeding experiment was conducted to study the feasibility of utilizing azolla (Azollapinnata) meal (AZM) as a replacement for soybean meal (SBM) in the diets for juvenile Penaeusmonodon. The replacement levels of azolla meal protein in the diets were 0, 25, 50, 75, and 100% of thetotal soybean meal protein. All diets were isonitrogenous at 40% crude protein. Shrimp (mean initialweight, 0.49±0.02 g) were fed three times daily ad libitum at an initial feeding allowance of 10% totalbody weight per day. A completely randomized design was used in the study and shrimp were stocked ata density of 10 animals/72 L-tank in triplicates. There were not significant differences in weight gains(1.97-2.06 g), specific growth rates (SGR 3.81-3.89%/d), feed conversion ratios (FCR 2.06-2.77),protein efficiency ratios (PER 0.89-1.24), apparent protein utilization (APU, 43.3-56.7%), and survivalrates (99.1-100%) among shrimp groups (P>0.05). Feeding preference tests showed that either soybeanmeal-based diet or azolla meal-based diet was similarly preferred (P>0.05) by shrimp with thepreference values of 51 and 40% for soybean meal-based diet and azolla meal-based diet, respectively.The results of this study suggest that azolla meal protein can replace up to 100% of the soybean mealprotein in practical diet for juvenile black tiger shrimp Penaeus monodon under laboratory conditionswithout any adverse performance. The use of azolla meal as an alternative plant protein source tosoybean meal may be able to reduce the feed costs for Penaeus monodon aquaculture.

redox potential (ORP), K value, black tiger shrimp (Penaeus monodon), scallop (Amusium sp.), storage temperature
Study on evaluation of fish freshness has been carried out using several parameters such as chemical, sensory, and physical parameter in which each has its own merits and demerits. Oxidation-reduction potential and K value are a physico-chemical and chemical methods available in assessing fish freshness which are both considered as objective methods. This study aimed to find out the effect of different temperatures storage on ORP and K value change of marine shellfish.
Material used in the study were black tiger shrimp (Penaeus monodon) and scallop (Amusium sp.). The experiment was laboratory experimental method. The samples were stored in room temperature (35±1oC) and refrigerated temperature (11±1oC). Analyses performed were ORP value (pH/ORP meter) and K-value (Ion-exchange chromatography method) and analysis were conducted in 4 replication. This study was carried out at laboratory of Fisheries Processing Technology, UNDIP Semarang and laboratory of PAU, UGM Yogyakarta.
The ORP of black tiger shrimp and scallop stored at refrigerated temperature initially were 0.23 Volts and 0.32 Volts. There were a maximum ORP of 0.3 Volts (shrimp) and 0.35 Volts (scallop) in the 2nd day of storage. These ORP then decreased to – 0.12 Volts and 0.01 Volts for shrimp and scallop, respectively. At room temperature storage, the ORP ranging from 0.26 to 0.33 Volts. This value consecutively decreased to – 0.17 Volts (shrimp) and – 0.16 Volts (scallop) after 32 hours storage. Initial K value of black tiger shrimp and scallop stored at room temperature were 1.32% and 1.51%, respectively and after 32 hours storage there were an increase in K value to 6.14% and 5.43%. Increase in K value was slower for samples stored at refrigerated temperature than that of room temperature.

Rocky shores provide an important habitat for marine organisms. This study aimed at providing baseline data on assemblage of organisms on rocky shores within the port-limit of Port-Louis, Mauritius. Four rocky shores, with three at Pointe aux Sables (La Pointe1, La Pointe2, and Petit Verger) and one at Baie du Tombeau were studied from October 2007 to February 2008. On each site three stations, located at intervals of 2m, with an area of 40m2 each were set up. Intertidal organisms were hand-collected within forty-eight, 1m2 quadrat for invertebrates. Observations of 16,061 specimens led to identification of 30 faunal species belonging mostly to phyla Mollusca and Arthropoda. Mean total abundance of invertebrates per 1m2 varied from 729.22±173.07 at la Pointe2 to 143.97±11.43 at Baie du Tombeau. The gastropod, Planaxis sulcatus was the most abundant species at La Pointe1 and Petit Verger with mean abundance of 196.86±179.71 and 168.10±113.44 per 1m2 respectively. The bivalve, Modiolus auriculatus was the dominant species with mean abundance of 673.33±762.04 per 1m2 at La Pointe2 and Nerita punctata was most abundant (39.41±57.35 per 1m2) at Baie du Tombeau. Lowest Shannon diversity was observed La Pointe 2. The study is useful for future work on port area.

Marine bacteria associated with soft coral Sarcophyton sp collected from vicinity of Peucang island, Ujung Kulon, West Java, were successfully screened for antifouling activity against marine biofilm-forming bacteria isolated from the surrounding colonies of Sarcophyton sp. Six bacterial isolates were found to inhibit the growth of at least one of 7 biofilm-forming isolates. The most active strain USP3.37 was identified as Pelagiobacter variabilis by using 16S rDNA gene sequence analysis. Similarly, the active strains USP3.3, USP8.43, USP3.12, USP3.16 and USP8.6 were identified as Arthrobacter nicotianae, Shewanella alga, Pseudomonas synxantha, Pseudomonas falgida, Pseudovibrio denitrificans and Bacillus aquamaris, respectively. USP3.37 strain was found to amplify gene fragments of non-ribosomal peptide synthetase (NRPS). This raises the possibility the use of softcoral bacteria as the source of antibacterial compounds for controlling the antifouling in the sea. Therefore, this bacterium would be better to select eco-friendly antifouling compounds than the other antibacterial activities.

PELLET WATER STABILITY STUDIES ON LUPIN MEAL BASED SHRIMP (Penaeus monodon) AQUACULTURE FEEDS : COMPARISON OF LUPIN MEAL WITH OTHER DIETARY PROTEIN SOURCES
Sudaryono, Agung
aquaculture, quality, water
Nutritional quality of lupin based shrimp (Penaeus monodon) aquaculture feeds was evaluated in terms of pellet water stability. Two series of water stability experiments were carried out to study the effects of lupin meal inclusions as an dietary protein alternative for fish meal (Experiment 1) and soybean meal (Experiment 2) on percentage dry matter and protein leachings of the compounded test diets. Increasing the replacement levels of dietary fish meal with lupin meal resulted in significant decrease (P<0.05) of pellet water stability over the 480-minute immersion period. A significant improvement in water stability with the increase of the soybean meal replacement levels with lupin meal up to 50% was found, however, further increase above 50% substitution level resulted in reduced water stability of the diets. It is concluded that lupin meal can not totally replace either fish meal or soybean meal in shrimp formulated diets and a 50% replacement level of dietary fish meal or dietary soybean meal with lupin gives a promising good result in terms of pellet water stability for P. monodon diets.

Live food, especially microalgae Skelotenoma sp. is a key success factor in shrimp aquaculture. To that end, the provision of Skeletonema sp. mass with a high nutrient content is needed. Nutritional quality of microalgae depends on the culture media used. The purpose of this study was to investigate effect of the use of different technical culture medium (Walne and Guillard) on the growth, protein content and fatty acid profile in microalgae culture Skelotenoma sp. Skeletonema sp. obtained from the Laboratory of Natural Feed BBPBAP Jepara. Culture method used was a mass with two different media (modified Walne and technical Guillard), with 12 replications. Data analysis were analyzed by using T test, while the protein content analysis was performed by Kjedahl method.The fatty acids were determined by using in situ transesterification. The results showed that the growth of Skeletonema sp. was markedly different between media Walne and technical Guillard. Guillard medium revealed lag phase after 44 hours (observation to 6) with a cell density of 48.00 x 104 cells/ml, then entered the exponential phase at 48. (Observation to 7) with a cell density of 70.25 x 104 cells / ml, while the stationary phase occurred in after hours to 52 (observation to 8) with a cell density of 86.75 x 104 cells / ml and death phase began at the 56 ( observations to 9) with a cell density of 54.58 x 104 cells / ml. Growth of Skeletonema sp. cultured with culture medium technical Walne showed a similar pattern in the lag phase to 44 hours of observation (observation to 6 with the cell density is 117.17 x 104sel/ml, exponential phase and stationary phase were detected from hour to 48 (observation to 7) with a cell density is 160.83 x 104 cells / ml. Later phases of death from an hour to 52 (observation to 8) with a cell density of 122.25 x 104 cells / ml. then long culvation or Skeletonema sp stationary phase in Guillard media over a period of 4 hours than Walne medium.

Heavy metal; Macrozoobenthos; Jakarta bay
Trace metal contamination of marine environments can be determined by measuring trace metal
concentration in sediments, water or biota. Biomonitor organisms have the advantages over other
measurements that they concentrate the portion of metals that are in a biologically available form, and this
portion which is usually of interest when assessments is being made of trace metal contamination.
Correspondingly, whole tissue trace metal concentrations of 4 metals in common Jakarta Bay benthic species
(polychaetes, molluscs, crustaceans) from contaminated locations were measured. The mean concentration
for Cu was 17.5 ± 21.8 μg g-1 dw in polychaetes, 11.9 ± 8.8 μg g-1 dw in molluscs, and 12.2 ± 5.5 μg g-1 dw in
crustaceans. The mean concentration for Cr was 172.8 ± 262.5 μg g-1 dw in polychaetes, 31.8 ± 62.8 μg g-1
dw in molluscs, and 28.5 ± 29.0 μg g-1 dw in crustaceans. The mean concentration for Zn was 152.4 ± 76.4
μg g-1 dw in polychaetes, 132.0 ± 106.3 μg g-1 dw in molluscs, and 515.8 ± 503.5 μg g-1 dw in crustaceans.
The mean concentration for Pb was 6.3 ± 13.6 μg g-1 dw in polychaetes and was 2.0 ± 4.5 μg g-1 dw in
molluscs. The study provides significant contribution to confirm the content of heavy metal in each common
benthic species inhabits coastal Jakarta Bay.

smoke-kiln-sawdust-liquid smoke-mackerel fish
Introduction : Smoking of fish has changed its function nowadays from just the preservative task to flavoring and coloring. The method of smoking has also been developed from traditional, which had used a simple technology to the modern method. In recent years, preparation of liquid smoke manufactured from certain varieties of wood pyrolysates have been successfully used as a substitute for the traditional smoking in a kiln.
Material and methods : The objective of this study was to compare the effect of cold smoking of mackerel fish on the proximate composition, water activity, salt content and microbial aspect of smoked fish treated using oak sawdust and liquid smoke either salted or un-salted. Sensory analysis was carried out by using score sheet organoleptic and hedonic test. Identification of pathogenic bacteria was done by API-20 E method. Factorial design was administered to compare the effect of traditional and liquid smoke method to brined and unbrined smoked fish.
Results and Discussion : The content of protein, lipid, water activity and salt of the two products were not significantly different (p>0.05). This means that the quality between two products were similar. Only moisture content of the products were very significantly different (p>0.01) caused by the phenomenon of osmosis between moisture of fish and brine. Study of liquid smoke treatment was found that liquid smoke was easier compared to oak sawdust smoke. It was also found that smoking reduces the number of colonies of bacteria. The number of colonies were about 1x103/g – 5x103/g after 2 day storage for unbrined smoked fish, while in brined smoked fish, no colonies were found after 3 day storage. Pseudomonas sp were present in both raw mackerel and the unbrined smoked fish sample, but were absent in the brined smoked fish.

FRESHNESS CHANGES OF YELLOWFIN TUNA (Thunnus albacares) DURING STORAGE AT LOW TEMPERATURES
Agustini, Tri Winarni
Fish freshness, yellowfin tuna, K value, low temperatures
Freshness quality is considered as an important factor in determining overall quality of particular fish product items. The degree to which the freshness quality of the items meets the consumer’s expectation concerning freshness quality will greatly affect whether the fisheries product item will be purchased again or not. Considering the importance of fish freshness quality, many methods have been proposed to evaluate fish freshness including physical, chemical and sensory methods. The K value is one of the chemical methods widely used , especially in Japan, as a fish freshness index to evaluate the quality change of raw fish. Tuna has been regarded as a palatable and valuable fish species and its freshness is the concern of many researchers.
This study is aimed at investigating the freshness change of yellowfin tuna (Thunnus albacares) during storage at low temperatures (10oC, 5oC and 0oC) by measuring the K value of the fish. Observation on the changes of ATP and its related compounds during storage was also carried out.
The result of the study shows that the freshness of yellowfin tuna as measured by K value, changed in different patterns depending on the storage temperatures. The higher the temperature of storage the faster was the decrease in freshness of yellowfin tuna. It was also observed that yellowfin tuna could be eaten raw up to 1 day, 2 days and 4 days storage at temperature of 10º C, 5º C and 0º C, respectively. Storage temperature of 0º C is recommended for its preservation in chilled state. The use of HPLC allows for each of ATP-related compounds to be determined quantitatively.The Ki value is more appropriate for measuring fish freshness obtained more than 24 hours after death

HERMAPHRODITISM IN Anadara granosa (L.) and Anadara antiquata (L.) (BIVALVIA: ARCIDAE) FROM CENTRAL JAVA
Afiati, Norma
A. granosa, A. antiquata, sequential protandric hermaphroditism
Gonad maturation and sexuality in Central Java populations of A. granosa and A. antiquata were studied by means of macroscopic examination of the visceral mass, microscopic examination of smears of gonadal products and by histological technique. In this study, hermaphrodites occurred extremely rarely, i.e. less than 1.5% for A. granosa and less than 1% for A. antiquata, were observed with both male and female gametes present within the same individual follicles. Unbalanced sex ratios derived from size frequency distribution of the sample revealed that the increased percentage of females with increasing size suggest the occurrence of sequential protandric hermaphrodite with only a single sex change during their life history, i.e. from male to female. The preponderance of juvenile males within the Wedung population should be seen as the advantage of firstly being male, since some energy could be saved and redirected towards somatic growth because in Bivalvia there is a trade-off between growth and reproduction.

Food consumption, nutritional status, underfive years old children, Fishermen family, monetary crisis
Since late 1997 Indonesia has been overwhelmed by monetary crisis and low income communities including fishermen received the worst impact of it. This study was intended to see whether there was a difference in food consumption and the nutritional status of the underfive years old children in the fishermen community before and during the crisis.
Sixty three subjects were chosen by cluster random sampling method and were followed from June 1998 to August 1999. Food consumption data were gathered by weighing method for two days and food frequency questionnaires. Paired t-test was used in the analysis.
The study revealed that the families income almost doubled, the food consumption was significantly increased in term of energy and protein. It was found that children have more frequent meal per day and more varieties of food eaten daily. The children’s weight and height increased in an average of 2.5 kg and 8.7 cm, respectively. The nutritional status in aggregate data showed an increase in height per age but slightly decrease in weight per age and weight per height indices but not statistically significant. By group analysis, more children had lower nutritional status in all indices.
It is concluded that there were improvement in food consumption of the underfive years old children, as the children grow older. However, their nutritional status became lower. The primary health care providers in the area should be informed on this situation. It is important that they should direct nutritional education program to improve the nutritional status of the children in its working area.

Octocorallia diversity, Singapore, toxicity of octocorals, brine shrimp lethality assay
The Southern Islands of Singapore are known to contain coral reefs which are high in biodiversity. However, the diversity of soft corals had received little attention to date. This study was conducted to determine the soft coral diversity in Singapore reefs as well as to conduct preliminary bioactivity tests on the organic extracts from these soft corals. A 100-meter line transect was used to survey soft corals at a 3m depth at ten different sample sites. Sclerites from samples were used to identify the soft corals to the generic level. This study uncovered the following genera of soft corals: Carijoa spp., Cladiella spp., Sinularia spp., Lobophytum spp., Sarcophyton spp., Stereonephthya spp., and Nephthea spp. In addition, an unidentified genus of soft coral was observed at Kusu Island. Cladiella spp. yielded the highest number of colonies, and Sarcophyton spp. had the highest coverage in terms of total colony diameter. The brine shrimp (Artemia salina) toxicity assay was carried out to screen for toxicity of the soft coral extracts at concentrations of 10, 100, and 1000 ppm. Results showed high levels of toxicity in extracts of Sarcophyton spp. and Cladiella spp., indicating that these soft corals are potentially good sources of bioactive compounds for drug discovery.

90Sr, East China Sea, North Pacific, currents, nuclear weapon testing
The condition of 90Sr concentration in the East China Sea and North Pacific closed to the Japanese island has been measured from 3 – 31 July 2000. There were differences condition of 90Sr concentration in the those locations. The concentration of 90Sr detected in the surface East China Sea and North Pacific ranged 0.44–1.32 mBq/ℓ and 0.66-1.38 mBq/ℓ respectively. Generally, the condition 90Sr concentration in the East China Sea was lower than in the North Pacific. The highest 90Sr concentration occurred in the off shore of North Pacific, because the 90Sr in the open sea is dominantly from nuclear weapon testing and nuclear power plant accident (Chernobyl) rather than other resources, and it take long time to precipitate into the bottom. Kuroshio and Taiwan-Tsushima warm current systems influenced importantly in distribution of 90Sr concentration in the East China Sea beside other physical factors such as fishing activity. These currents were not strong enough to stimulate increasing 90Sr concentration in the coastal region of North Pacific close to the Japanese islands.

STABILITY OF LOCAL RAW MATERIALS FOR MUD CRAB FEED DEVELOPMENT
Hutabarat, Johannes
local raw materials, nutritional values, mud crab feed development, fattening culture
The aims of study were to identify the potency and nutritional values of local raw materials available in Central java, and to develop the mud crab feed using selected raw materials for its deffatening culture.
The potency level of local raw materials was determined by using secondary data available in relevant technical institution e.g. Agriculture Department, Fisheries Bureau and followed by direct site survey in the production centre of agriculture and fisheries by catch in Central Java, i.e Pekalongan, Kendal, Semarang, Jepara, Pati and Rembang. Data obtained were analyzed descriptively to determine the resource of the potentials of local raw materials and followed by determining their nutritional values, profile and availability of assential amino acids (EAA) and essential fatty acids (EFA), using standard method available. The results indicated that the local raw materials for protein sources are found in abundance in Central Java throughout the year with relatively cheap price i.e: trash fish, mysid, squid, blood meals, worm-meals and shrimp head-meals (animal protein) and saga, soybeans (plant protein). The protein level of selected raw materials were high (41.15% – 80.35%) and the highest level was found in blood meal and followed by squid, trash fish and shrimp head meals.
The selected raw materials, generally contains 10 essential amino acids (Arginine, lysine, histidine, phenylalanine, leucine, isoleucine, methionine, valine, threonine, and trypthophane) and a long chain of EFA (n-3 HUFA) and (n-6 HUFA) which are required by mud crab for their growth. The selected local raw materials are therefore nutritionally suitable for mud crab feed development in Central Java.

THE IMPROVEMENT OF BUILDINGS AND INFRASTRUCTURE CONDITION TO ANTICIPATE DEGRADATION PROCESS OF FISH-SMOKING CENTRE IN BANDARHARJO, SEMARANG
Hardiman, Gagoek
Fish-smoking buildings; high-tide; degradation; infrastructure
The fish-smoking area in Bandarharjo is one of the significant industrial centers that processes fish as coastal resources. Its existence is crucial to support the characteristic of Semarang as a coastal city. The fish-smoking area, located on the bank of Semarang River, has existed since 1986. Local people keep maintaining the activities of smoking fish regardless the poor physical condition of the buildings and environmental infrastructure as a result of the high tide. In order to maintain the sustainability of fish-smoking activities, a research on the convenience of working space, physical condition of the building, and environmental infrastructure is needed. Considering that fish-smoking industry can provide jobs for low educated people and produce alternative food for the people living in Semarang, therefore, the degrading condition of the buildings and environment in Bandarhardjo needs to be anticipated by applying the concept of space, building and environmental infrastructure quality improvement.

Shrimp shell waste from seafood restaurants and canned shrimp industries is potential to be used as chitosan source. This material contains 18.1% of chitin which could be converted into chitosan through demineralization, deproteination and deacetylation process. Chitosan is fine chemical used to adsorb fat from body, heavy metal absorbent, fat diluent and medicine. This research looked into the prospect of chitosan from shrimp shell as fats dilluent. The aims of this research are to study the influence of NaOH concentration on preparing chitosan from shrimp shell, and evaluate the performance of chitosan produced as fat diluent. As indicators, the purity of chitosan and the percentage of fats diluted are measured. This investigation was conducted in two steps involving the preparation of chitosan and the process optimation of fats dillution using chitosan. In this case, the NaOH concentration was varied from 20% to 60% with the step size of 10% to obtain highest quality of chitosan. Whereas, in the second step, the time of fats dilution and chitosan quality were varied to obtain optimum condition of fats dillution. The dillution time was varied from 10 to 30 minutes with incremental of 5 minutes. While, the chitosan quality was varied based the result of preparation step. The results indicated that the highest chitosan quality of 82.45% could be obtained in the percentage of NaOH of 60%. Meanwhile, in the fats dillution process, it showed that the highest percentage of fats dilluted is 96.57% that could be achieved at time dillution of 10 minute and chitosan quality of 82.45%.

Fine shrimp; Metapenaeus, Elegans; Molting; Osmotic; Salinity
A research on eco-physiological characteristics of fine shrimp (Metapenaeus elegans) with special emphasis on the osmotic responses and isosmotic medium requirement for adult spawners in various molting stages was conducted. Adult stocks of M. elegans origin from the Segara Anakan lagunas of the South West of Central Java region were collected and used as experimental shrimps. The shrimps were hold in three 500 l-acclimation tanks and treated according to Anggoro and Nakamura’s method. The seawater salinity level in the tank 1, 2, and 3 was 25, 28, and 22 ppt, respectively. Osmotic response of the shrimps was examined during 3 molting stages, i.e. pre-molt/ post-molt, molt, and inter-molt phases by using an automatic microosmometer Roebling. The results showed that osmotic responses were closely related to the salinity of water medium and molting stages. It was also found that the minimum osmotic works of fine shrimp occurred in isosmotic medium, i.e. 16 to 20 ppt for post-molt, 28 to 30 ppt for molt, and 22 to 25 ppt for inter-molt stages. It was concluded that the range of isosmotic media for the adult of fine shrimp was 22 to 28 ppt or equals to 642.06 to 817.31 mOsm/l H2O.

The Mediterranean coast of Gaza strip, which is covered about 40 km in length, is rich by coastal resources. The development that occurred along the coastal lines has led to the host of problems such as increased erosion, siltation, loss of coastal resources and the destruction of the fragile marine habitats. In order to conserve the depleting coastal resources, the changes due to development and associated activities must be monitored. Studying the temporal pattern of shoreline change is considered one of the most effective means of monitoring the cumulative effects of different activities. An attempt was made to study the impact of Gaza harbour on shoreline displacement along 6 km. This paper was intended to detect changes of coastal area in Gaza city to provide future database in coastal management studies. The analysis was carried out using image processing technique (ERDAS) and Geographical Information System platform. The variation during 38 years in the shoreline along the Gaza coast was determined by analyzing MSS, TM and ETM Landsat images from 1972 to 2010. The analyses identified the erosion and accretion patterns along the coast. The shoreline was advanced south of the Gaza fishing harbor, where the wave-induced littoral transport was halted by southern breakwater and the annual beach growth rate was 15,900 m2. On the downdrift side of the harbor, the shoreline was retreating and beaches erode at an annual rate of -14,000 m2. This study was emphasized that the coastal band is considered as a critical area, it is therefore necessary to monitor coastal zone changes because of the importance of environmental parameter and human disturbance. In particular, the projections of future shoreline erosion and accretion rates are considered important for long-term planning and environmental assessment for a variety of projects, including the construction and tourism facilities.

Seventeen strains of bacterial symbionts which are resistant to heavy metals, were isolated from the tissue of coral Goniastrea aspera, from Awur Bay, Jepara Waters. Screening procedures involving solid and liquid synthetic media containing Cd2+, resulted in the selection of seven Cd resistant strains, which showed a quantitative removal of Cd2+ by range of 68-90% of the initial Cd2+ concentrations (5 ppm) tested. One of these strains, CD15, was selected further to examine its molecular and physiological characteristics. Based on 16S ribosomal DNA sequencing and microbial characterization, the CG15 isolate is closely related to Pseudoalteromonas sp. This is the first report on the natural Cd metal tolerance levels of coral bacteria

NEW EMPIRICAL FORMULAE OF UNDERTOW VELOCITY ON MIXED AND GRAVEL BEACHES

gravel, mixed beach, wave-induced currents, trench, wave breaking, undertow
This paper reports a series of 3-dimensional physical model tests to measure cross-shore current data, generated by oblique wave attack, along gravel and mixed beaches with a uniform slope and a trench. Coastal managers and coastal engineers are beginning to give attention to gravel and mixed beaches due to the fact that they are two of the most effective natural sea defences.There is a need, from a scientific and coastal management perspective to have a deeper understanding of how gravel and mixed beaches operate.The studies described in this paper aim to investigate the behaviour of the undertow velocity on mixed and gravel beaches. Existing formulae have been used to predict the experimental results and new equations for predicting the undertow velocity under these conditions are proposed.
The new empirical formulae predict time- and depth-averaged undertow and are based on a nonlinear regression of a modification of the Grasmeijer’s and Ruessink’s model where the zones where divided based on the related distance of the point of interest and the breaking point. Verification with large-scale experiments showed that the new formulae predicted well the undertow velocities on mixed and gravel beach with trench and uniform slope.
