Handayani, Muliawati
Anggoro, Sutrisno
Widowati, Ita
Hideyuki, Imai
The study was conducted to determine the genetic diversity of Calcinus elegans based on sequences of the COI mitochondrial DNA. Successfully 54 samples of Garut; 43 of Yogyakarta and 47 of Banyuwangi populations were amplified by PCR using universal primers LCO 1490 and HCO 2198 successfully amplified COI gene in 625 bp, with an overall haplotype totaled 64 at 111 polymorphic sites. All population showed high genetic diversity within population interpreted by the value of gene diversity (H): Garut is 0.9266 ± 0.0251; Yogyakarta is 0.9668 ± 0.0156 and Banyuwangi is 0.9288 ± 0.0257 and the value of nucleotide diversity (π): Garut is 0.007155 ± 0.003972; Yogyakarta is 0.007966 ± 0.004387 and Banyuwangi is 0.00723 ± 0.004021. Gene diversity and nucleotide diversity did not differ significantly between populations. While genetic diversity among populations interpreted from haplotypes similarity or shared haplotype. Number of shared haplotypes among three populations is 12 haplotypes with 90 samples included. Banyuwangi population showed smallest intensity interaction with other populations indicated by the smallest value of haplotypes; polymorphic sites; hetorozigosity and distribution of larvae are influenced by spatial factor. However, three populations come from one ancestors and part of a large population. Thus the current and other environmental factors in South Coast of Java Island are effected on the genetic diversity among populations of C. elegans with a correlation coefficient is r = 0.98 (genetic diversity with current) and r = >0.90 (genetic diversity with temperature, salinity, pH, depth and distance). Key words: Calcinus elegans, genetic diversity, COI, mitochondrial DNA, haplotype

Dwi, Agus Anugroho
Sulaiman, Muhammad
ABSTRACTCilalanangriver located in the village of EretanWetan, District Indramayu. There are Fishery Harbor Beach (PPP) and shipping activities in this region is quite high. Activities in the PPP could potentially lead to silting due to the material carried by the river flow. The purpose of this study to determine the concentration of total suspended sediment (TSS) and the influence of ocean currents on the TSS in Cilalanang Estuary, District Indramayu. The research is located at coordinates 1080 4’ 53.400” EL -1080 5’ 50.215” EL and 60 19’ 26.709” SL - 6019’ 26.720” SL. The method used in this research is quantitative method. Analysis of the TSS is done by making the TSS distribution maps using ArcGIS10.5 and modeling ocean currents using MIKE 21. The results showed that the concentration of TSS at low tide toward the high tide is worth between 286-888 mg / l whereas when the high tide towards low tide worth between 348-553 mg / l. Dominant ocean current direction at the time of low tide to the hightide leads to the southwest. This causes TSS concentration coming out of the mouth of the river converge toward the southwest near the shore. In conditions of high tide toward low tide the dominant current direction leads to the northeast. This led to the spread of TSS concentration coming out mouth of the river away from the shore. Key words: Cilalanang River, IndramayuDistrict,Ocean Currents, Ocean Tides, Total Suspended Solids

Potentiality of Using Spreading Sargassum Species from Indonesia as an Interesting Source of Antibacterial and Radical Scavenging Compounds: A Preliminary Study
Widowati, Ita
Puspita, Maya
Stiger-Pouvreau, Valerie
Bourgougnon, Nathalie
As an archipelagic country with 95,181 km long coastline, Indonesia has great potential as the producer of seaweeds. The diverse phyla of marine macroalgae (red, brown and green seaweeds) are known to produce molecules which are attractive for diverse industries. Applications of algal products range from simple biomass production for food, feed and fuels to valuable products such as sugar polymers, cosmetics, pharmaceuticals, pigments, and food supplements. Seaweeds also have the potential to be used as a source of new bioactive for human, animal or plant health, as well as a source of new synthons and biocatalysts in sustainable chemistry (Bourgougnon and Stiger-Pouvreau, 2011). In this paper, among species of economic value we focus on brown seaweeds belonging to family Sargassaceae and genus Sargassum spreading along Indonesian coasts. Members of this genus are especially abundant in tropical and subtropical regions (Zemke-White and Ohno, 1999). The purpose of this study is to analyze the antibacterial and antioxidant activity of three species of Sargassum, i.e. S. echinocarpum, S. duplicatum and S. polycystum. Both polar and non-polar extracts have been prepared from those three species. In vitro antibacterial activities of extracts were evaluated against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli. Results indicated all the three species tested showed an antibacterial activity. The most effective antibacterial activity against S. aerous was from S. echinocarpum with ethil asetat, inhibition zone 1.13 ± 0.25 mm; S. duplicatum with N-Hexane was most effective against E. coli, 1.20 ± 0.28 mm. Key words: Antibacterial, Sargassum, Staphylococcus aureus, Escherichia coli.

Allelopathy Effect of the Blue Diatom HasleaOstrearia (Gaillon) Simonsen: Growth Inhibition in Aquaculture Relevant Microalgae
Windarto, Eko
Prasetiya, Fiddy Semba
Mouget, Jean-Luc
Gastineau, Romain
We are well known that the marine pennate diatom Hasleaostrearia (Gaillon) Simonsen produces the blue-green pigment called marennine. Marennine was identified as a polyphenolic compound. This compound is capable to inhibit the growth of herpes simplex virus type 1 (HSV-1) and several bacteria, including pathogens as Vibrio sp. The aim of this study was to determine how strong the allelophatic effect of marennine is generated byH. ostrearia and identifying its minimal concentration that inhibits the growth of other microalgae. The experiment consisted of two phases of research activities. The first phase was biovolumecomparaison between H. ostrearia and microalgae suitable for aquaculture tested to take into account the differences in size of the microalgae tested(Tetraselmissuecica, Chaetocerosgracilis, Skeletonemacostatum, PavlovalutheriandIsochrysisgalbana (T-Iso) in term of H. ostrearia biomass and production of marennine. The second phase was the bioactivity tests, which is include growth kinetics, allelophatic effects and concentration of marennine in the culture medium, measured with spectrophotometer. The results of this study showed that H. ostrearia could inhibit several species of microalgae currently used in aquaculture (T. suecica, C. gracilis and S. costatum). The statistical analysis (One way ANOVA) showed that there are significant differences (P < 0, 05) between treatments andwhen co-cultured with H. ostrearia, these microalgae exhibited a significant growth inhibition. The highest inhibition value was 97.77% (on the treatementH. ostrearia+C. gracilis). In this treatment, the concentration of marennine in the culture was 5.35 mg L-1. According to the results, we can conclude that the supernatant of H. ostrearia with marennine acts as an allelochemical. The minimal concentration is 0.23 mg L-1 and the highest is 5.35 mg L-1. The treatments H. ostreariawithP. lutheri and T-Iso did not performed any inhibition. Key words: H. ostrearia, marennine, microalgae and Allelopathic effect.

Wijayanto, Dian
Sugianto, F.X.
Poerwono, D.
The purpose of this study was to develop the model of profit estimation in Aquaculture. This research used a model of von Bertalanffy length growth combined with the length-weight relationship, and developed an equation of time harvest to produce the target of fish weight as the market preferences. That also developed an equation to estimate the fish biomass, and the profit in aquaculture. The Profit is a total of revenue minus total of cost. Both the harvested biomass of fish and price of fish affect the revenue of aquaculture. The components of costs were a cost of seed procurement, cost of feed procurement, cost of transportation of products and the daily cost. The daily cost of aquaculture in floating cages were a cost of labour, cost of vitamins, cost of energy, cost of assets depreciation, cost of supporting equipment and cost of maintenance assets that converted to IDR (Indonesian Rupiah) (day) -1. The research proved if lthe model in this study could be used to estimate the profit of aquaculture. In case of red Tilapia culture (floating cage) in Reservoir of Wadaslintang, aquaculture at 120 days produced a fish average weight of 200 g (profit IDR. 13,507,167), then at 143 days produced 250 g (profit IDR. 17,975,723), at 164 days produced 300 g (profit IDR. 21,853,697), at 185 days produced 350 g (profit IDR. 25,387,418), at 204 days produced 400 g (profit IDR. 28,181,081), at 223 days produced 450 g (profit IDR. 30,507,200), and at 242 days produced 500 g (profit IDR. 32,297,418).

ABSTRACTMangrove forrest is an coastal ecosystem which has so many advantages and usages. Mangrove forrest has ecological functions as carbon sink. This function becomes very important because of the increased greenhouse gas (GHG) emissions in the atmosphere causing climate change. Climate change raises the temperature on the surface of the earth, thus threatening the existence of humans and other living things. The purpose of this research was to determine the amount of biomass, carbon reserve, CO2 absorption and soil organic carbon in mangrove vegetation Ujung Piring, Jepara.The method used in this research was descriptive and location determined by purposive sampling, which is divided into three locations, in each location used 2-3 x sampling. The data were collected using a 10 x 10 m plot. Determination of stored biomass in stands using non-destructive sampling by measuring stem diameter (Dbh) and allometric equation on each mangrove species. Carbon stock was determined using the results of biomass determination, whereas CO2 absorption was determined using carbon stock. Soil organic carbon is determined using the results of organic matter measurement.The result showed that 6 mangroves species were found in the research plots: Rhizophora apiculata, Rhizophora mucronata, Ceriops tagal, Lumnitzera racemosa, Sonneratia alba, and Sonneratia caseolaris. The largest carbon stock value is in Location I with the dominance of R.apiculata. The carbon stock of mangrove vegetation has a linear relationship with soil organic carbon. Ujung Piring has amount of biomass 16,69 ton/ha, carbon stock 7,85 ton/ha, CO2 absorption 28,76 ton/ha and soil organic carbon 1706 ton/ha.

Wijayanto, D.
Sugiyanto, F. X.
Poerwono, D.
ABSTRACTThe purpose of this study was to develop the optimal harvest time to generate maximum profits in Aquaculture. This study used a model of von Bertalanffy length growth combined with the length-weight relationship and the mortality rate to estimate of fish biomass. Profit was calculated as total of revenue minus total of cost. Both the harvested biomass of fish and price of fish were determined as factors affected the revenue of aquaculture. The components of costs were cost of seed procurement, cost of feed procurement, cost of harvesting transportation and the daily cost. The daily cost of aquaculture in floating cages are cost of labour, cost of medicines, cost of energy, cost of assets depreciation, cost of supporting equipment and cost of maintenance assets that converted to IDR/day. Profit maximization was performed by derivative the equation of profit to aquaculture periods (first order condition), and its second derivatives was negative (second order condition). The research model was applied to the red Tilapia culture in floating cages at the Reservoir of Wadaslintang, Indonesia. The research results demonstrate that the model in this study can be used to estimate aquaculture periods (286 days) which can generates maximum profits.

Toward a New Paradigm of Ecosystem and Endemic Organism based on Spatial Zonation for Taka Bonerate Marine Protected Area
Hartoko, Agus
Kumalasari, I.
Anggoro, Sutrisno
Most of present approach by authorities in designing for any conservation programs was mainly achieving target based on the width of area and not for the endemic organisms in each area. The old zonation method used was usually not based upon an ecological delineation but mostly using the island border physically and without a rehabilitation zone. In the conservation zone such as in Taka Bonerate marine park there could be a limited use zone based on the traditional use and not an intensive use activities. The paper develop a new ecosystem and endemic organism based spatial scoring to built a new spatial zonation model which is specially dedicated for any conservation zone or a marine parks. Which would be used for a management plan and further action plan. A spatial based approach analysis with a reliable detail and adequate accuracy was needed as a guide in the zonation processes for the management of coastal or marine protected area. The spatial modeling was a combination of satellite and field data analysis. This spatial modeling analysis was also called as Cell Based Modeling based on raster/spatial data and ‘spatial-scoring’ method with emphasized on the specific ecosystem and endemic organism valuation and weight approach. The new paradigm on the “specific ecosystem and endemic organism based spatial-scoring for a new spatial model” and targeted existing knowledge for a beyond ‘the usual-goals’ for Marine Protected Area (MPA). In this case is preserving and conserving “marine living fossils”: Nautilus pompilus for Taka Bonerate as well as for other cases of Latimeria menadoensis in north Sulawesi waters and Limulus.sp in Java and Kangean seas, should be designated as a “new concept of MPA-Plus”. Considering the important of deep sea vulnerable reef and atolls and sand-dune (‘bungin’) ecosystem for a protected reef-fishes: napoleon wrasse (Cheilinus undulatus), and flying fish Cypsilurus.sp and others. Key words : Endemic, spatial-scoring, MPA, Taka Bonerate

Optimization and Stability of Total Pigments Production of Fusan from Protoplast Fusion of Microalgae Dunaliella and Chlorella in vivo: Attempts on Production of Sustainable Aquaculture Natural Food
Kusumaningrum, Hermin Pancasakti
Zainuri, Muhammad
Diversification of feed rich in natural carotenoids is needed in aquaculture because they will increase survival and body weight of animal farming. Different types of important carotenoids such as β-carotene, zeaxanthine can be combined through a process of protoplast fusion making it cheaper and faster. Crustaceans can not synthetize carotenoid de novo and they need it to provide nutrition and possibly disease resistance, pigmentation and esthetic value. Green microalgae produce carotenoids and can be manipulated easily by protoplast fusion. The research was conducted to obtain some fusants from interspesies protoplast fusion of D. salina and C. vulgaris. Interspecies protoplas fusion was carried out by protoplast isolation, protoplast fusion and protoplast regeneration. Microscopic and cell analysis will used to confirm positive regenerate protoplast. Analysis of the obtained fusants is limited to morphological description due to the complexity and variability of fusant. The stabilities of fusants obtained were examined by successive subcultures. The result revealed that the fusant from D. salina and C. vulgaris maintain their stability in growth and increased carotenoid production during four periods of subculturing. This result suggesting the potency of fusant to be used as food supplement. Key words: Carotenoid, Protoplast fusion, Dunaliella, Chlorella

ABSTRACTLiran Island waters are located between two seas, the Banda Sea and the Timor Sea. These waters are also the border between Republic of Indonesia and the Democratic Republic of Timor Leste (RDTL). The thickness of mixed layer depth in Liran Island waters are vary. This is assumed as a result of the influence of transition season I wind that blew in the area in April 2016. This study aims to determine the variation of the thickness layer mixed layer Liran Island waters, Southwest Maluku District on April 2016 caused by the transition season I wind. The methodology that used in this research is descriptive method with quantitative approach. The main data that used in this study is in situ sea temperature data, while the supporting data that used in this study is wind data which measured directly in the field for 9 days. The result of this research is based on determination of layer mixed layer using criterion ΔT = 1.0 0C. The west part of Liran Island had thinnest layer mixed layer depth that is about 20 - 38 m. The east part of Liran Island waters had the thickest mixed layer depth which up to 55 m. Meanwhile, the north part of Liran Island waters had a thickness of mixed layer between the eastern and western waters of 40 m. This related to the wind that blowing from the southwest to the northeast and causing a downwelling phenomenon in the east part of Liran Island waters and upwelling phenomenon in the west part of Liran Island waters while the north part of Liran Island waters did not get a great influence from the movement of the wind because of its location which protected by Liran Island itself. Key words: mixed layer depth, the transitional monsoon I, Liran Island waters

Translocation Study of Some Zooxanthellae Clade to the Survival and Growth of Goniastrea aspera after Bleaching
Purnomo, Pujiono W.
Inter-host translocation technique of zooxanthellae was attempted to prove Buddemier and Futin’s (1993) theory on adaptation. The recent trend of coral products trading must be anticipated by its mass production through artificial techniques, the alternation of natural resources. Translocation bio-technique of zooxanthellae on coral was expected to resolve the problem and the translocation study should provide fundamental answer to coral recovery. The study of zooxanthellae translocation was proposed to: a) Evaluate the effect of zooxanthellae enrichment on its translocation on coral polyp tissue efter optimum bleaching and b) Investigate the effect of translocation on coral growth. The research was experimental, involving coral species Goneastrea aspera, and purified zooxanthellae clade A, B and C with circulating incubation condition in BPBBAP Jepara indoor area. The experiment took place for 30 weeks in both model environment waters and natural environment waters of Jepara Panjang Island coral area from March to August 2008. The result showed that: a) In the artificial waters, translocation zooxanthellae to polyp tissue of Goneastrea aspera occured at day 17 and more fast in the natural waters; b) In the controlling of temperature environment on translocation provided positive response of Goneastrea aspera’s normal life, relocation and growth rate of zooxanthellae as in nature and c) recognition, resettlement, and growth process of zooxanthellae made it possible for Goneastrea aspera to grow normally in natural waters. Key words: Clade, bleaching, recognition, resettlement, growth, translocation, zooxanthellae, Goneastrea aspera

The presence of aeration on the cultivation of polyculture system can eliminate oxygen depletion at night while the intensity of light would effect the seaweed Gracilaria verucosa to perform photosynthesis. The supplies of oxygen is to eliminate the oxygen depletion at night until morning, and propose the efficiency of feeding activity, and also stabilize the water quality. The purpose of this research is to improve the survival, growth and production of vaname shrimp, and Gracilaria verucosa. This research was conducted in Jepara Brackishwater Aquaculture Research and Development Center (BBPBAP), from May until August 2013. A number of 75 shrimps and 1,750 g Gracilaria vericosa were cultivated in the 800 L tank, which observed for 96 days. There are four type of treatments, oxygen supply O1 (3,500 lux light intensity), O2 (Aeration with 700 mL minute-1 speed), O3 (light intensity and aeration), O4 (without light and aeration), three replications. This research was conducted using an experimental Randomized Block Design. The survival rate and growth of shrimp (Litopenaeus vannamei) showed a highly significant (p < 0.01) different between the treatments, while the growth and biomass production of seaweed (Gracilaria verucosa) showed a significantly (p < 0.05) different. The three treatments of oxygen and light supply, aeration and the combination of light and aeration, it can be concluded that survival, growth and production of vaname shrimp and Gracilaria verucosa. The combination of light and aeration treatment is the best, it can be concluded survival rate of shrimp (94.64%) compare to the treatment without oxygen (45.24%). Absolute growth rate of shrimp increased from 9.57 g to 12.97 g. The specific growth rate of shrimp increased from 4.73% to 5.07%. The biomass production of shrimp increased from 181.56 g m-2 to 883.95 g m-2. The combination of light and aeration can improve the absolute growth rate of Gracilaria verucosa from 25.86 g to 52.724 g. The specific growth rate of seaweed increased from 1.77% to 2.64% then biomass production of Gracilaria verucosa also to increase from 2,557.76 g to 5,063.2 g.

Dewi, Rose
Zainuri, Muhammad
Anggoro, Sutrisno
Winanto, Tjahjo
Endrawati, Hadi
ABSTRACTLagoon Area of Segara Anakan (SAL) have influence of natural and anthropogenic factors impacting on the increasing of macronutrient, ecologically SAL is downstream from several rivers watershed Citanduy. SAL is tropically moist and influenced monsoon wind, causing the fluctuated waters. The purpose of this research is to recognise the characteristic spatio-temporal makronutrien lagoon. The measurements of macronutrient, include: TN (Total of Nitrogen), NH3 (Ammonia), NO3- (Nitrate), TP (Total of Phosphate), and PO43- (Orthophospat), using methods of spectrophotometric and micro-kjeldahl. The spatial approach is done on 7 stations (S) with representations: (S) natural factors and (S) the presence of anthropogenic activities. The temporal approach (time series) for a year refers to the monsoon wind pattern (west, transition I, east and transition II) season. The results of laboratory tests are discussed descriptively and adapted to the Indonesian standart of waters quality. To facilitate spatio-temporal interpretation, the data is presented formingly a thematic map. Temporal results show in the west season, the highest macronutrient content is dominated by TN (0.587 ± 0.223) mg / L, NH3 (0.875 ± 1.290) mg / L and PO43- (0.390 ± 0.909) mg / L, while NO3- (0.185 ± 0.015 ) mg / L and TP (0.155 ± 0.026) mg / L highest during transitional season II. In the spatial approach, (S) with anthropogenic characteristics contribute to the whole height of the macronutrients. The effects of rainfall, anthropogenic pressure, aquatic hydrodynamics and the contribution of metabolic waste discharged from organisms, are thought to cause in the increasing of SAL macronutrients. Management and lagoon management strategies are required by the local government, stakeholders and communities to prevent the phenomenon of eutrophication of the lagoon. Key words: Macronutrient, Nitrogen, Phospate, lagoon of Segara Anakan

Effect of Mineral Suplement in the Diet for Penaeus monodon F. Shrimp Culture in a Low Salinity Medium
Djuwito, Djuwito
Anggoro, Sutrisno
Hutabarat, Johanes
Shrimp culture in a low salinity medium has been developed widely such as in Thailand, China, Indonesia and some Federal country of USA. This new approach of shrimp culture of the tiger prawn Penaeus monodon Fab was done as low salinity shrimp farming; low-salinity inland system, inland shrimp farming, and inland culture. Water source was then treated with a step-wise dilution process with river waters to the salinity range of 25-30 ppt to be used for post-larval rearing and growing. The process of dilution will continue to salinity of 5 ppt to be used for the growing ponds until harvest. The relocation of conventional brakish water ponds for shrimp culture from coastal area to inland area was initially caused by the problems of desease, marine pollutions, environmental issues such as mangrove destructions issues and the change of spatial planning in coastal area. The aim of the study is known the effect of K+ and Mg2+ addition and its combination to the weekly growth rate (based on weight) of the shrimp and Osmotic Capacity. The study using addition of mineral in the diet with assumtion that this approach will have more effective effects to the specific growth rate (SGR), Absolute Growth (∆G), survival rate (SR) and osmotic capability (OC) of the shrimp. The experiment design was Complete Random Design with 3 replicates for each treatment. Treatment A: standard diet added with 1% K (1 gr KCl/100 gr diet), treatment B: standard diet adde with 1% Mg2+ (1 gr dolomite/100 gr diet), treatment C was a combined of 0.5% K+ and 0.5% Mg2+, and treatment D was standard diet without mineral (as control). Result of data analysis using ANOVA revealed that all mineral diet treatment had no significant effect (P > 0.05) to SGR and ∆G for Penaeus monodon cultured in low salinity. Although a combined mineral (K and Mg) treatment C had shows the highest of absolute growth (0.7023 gr) then followed by treatment A (0.6421 gr), B (0.5303 gr), and D (0.4951 gr). The treatment of C with combination of 0.5% K and 0.5% Mg had gave the highest absolute growth and provide the best result. The weekly specific growth rate (SGR) had shown a steady decreasing pattern, with the lowest rate in week-5 and increase again in week-6. All mineral suplement in the diet had revealed a significant effect to the osmoregulatory capacity (OC) with (P value < 0.05) with seawater medium variabel as already mentions earlier. All treatments had gave high survival rate (SR) of the Penaeus monodon post-larvae where treatment A: 95.83%; B: 5.83%; C: 91.67% and control D : 85.50%.
