Quail child has a tremendous potential to continue further descent because quails have almost all the potential that can be exploited by humans, either for consumption or economic. Children quail superior quality can be produced from superior quality parent, so the parent quail quality must be considered. Additional food in the form of powder turmeric supplements can increase the phytoestrogen which stimulates the liver to produce vitellogenin as the material forming the yolk. Egg yolk is a source of nutrients for the development of quail embryos. This study aimed to analyze the differences in the quality of the parent male quail chicks were given supplements of turmeric powder to the testis weight, testis size, number of spermatogonia and spermatids amount contained in the seminiferous tubules. The study design used was completely randomized design (CRD) that is 3 treatments and 5 replications. By using quail male child as much as 15 tails as test animals, divided into three groups, namely K0: F1 generation of the female quail are not given turmeric powder supplement, K1: F1 generation of the female quail turmeric powder supplemented with a dose of 54 mg/tail/day and K2: kuturunan F1 of the parent quail turmeric powder supplemented with a dose of 108 mg/tail/day. The variables measured were testis weight, testis size, number of spermatogonia and spermatids number. Data were analyzed using Analysis of Variance (ANOVA) followed by a further test Duncan Multiple Range Test (DMRT) at the 95% significance level. The results showed that the quality of parent child quail turmeric powder supplemented with a dose of 108 mg/tail/day for better views of the process of spermatogenesis.

Hutan mangrove memiliki banyak fungsi secara ekologi seperti menahan dan menjebak sedimen, meredam gelombang, memberi perlindungan bagi ikan dan biota lainnya, dan mengasimilasi nutrien. Unsur hara yang dikembalikan ke lantai hutan sebagian besar adalah dalam bentuk serasah. Serasah yang jatuh akan menyediakan karbon organik penting bagi ekosistem. Penelitian ini bertujuan untuk mengukur produktivitas dan kandungan karbon serasah mangrove di hutan mangrove Desa Kurau Timur. Metode yang digunakan untuk mengukur produksi karbon serasah yaitu dengan pengumpulan serasah menggunakan perangkap (litter trap) yang berukuran 1m x 1m dengan pengambilan serasah setiap 7 hari selama 3 bulan, sedangkan pengukuran kandungan karbon dilakukan dengan metode Loss on Ignition (LOI) pada suhu 550˚C selama 4 jam. Analisis data parameter lingkungan dilakukan dengan PCA (Principal Component Analysis). Komposisi vegetasi pada hutan mangrove Desa Kurau Timur yaitu 6 jenis yang merupakan mangrove sejati. Persentase kandungan karbon dari sampel serasah yang didapatkan adalah sebesar 53,71% dengan perkiraan produksi karbon 2,28 gr/m2/hari atau 6,85 ton/ha/tahun. Lapisan serasah di lantai hutan mangrove Desa Kurau Timur yaitu dengan berat kering rata-rata 85,92 gram, kandungan air 40,92%, dan perkiraan biomassa rata-rata 3,44 ton/ha. Parameter lingkungan yang paling berpengaruh terhadap produksi serasah adalah DO (kadar oksigen), sedangkan kandungan karbon serasah lebih dipengaruhi oleh pH dibandingkan parameter lainnya. Semakin tinggi pH pada kawasan tersebut, maka hasil produksi karbon serasah lebih tinggi.

Izzati, Munifatul
Rawa Pening is a semi natural lake which is utilized for hydro-electric power plant, caged fish culture, irrigation, and tourism. It belongs to one of the fifteen lakes which receives national priority to be saved and preserved because of its very poor condition as a result of eutrophication, sedimentation and degraded water quality. Eutrophication of Rawa Pening comes from the Water Catchment Area, originating from farms, animal husbandry, domestic and industrial waste around the lake, and also from the water body itself, that is from caged fish culture. The fertility criteria of the lake water can be determined on the basis of the abundance and variety of phytoplankton and the total phosphorus content.
The aim of this research is to find out the water fertility criteria of Lake Rawa Pening based on the abundance and variety of phytoplankton, and the phosphorus content. Research began in July 2012 on three stations. Station I is an area with fishcage culture; Station II is an area without fishcage culture, and Station III is the river inlet or water catchment area. Each station consisted of three different sampling areas.
The phytoplankton abundance at the station without fishcage culture is higher (19012 ind/l) than at the fishcage culture station (14356 ind/l) as well as at the inlet station (11058 ind/l), but the diversity index at the no fishcage station is lowest (1.80) compared to the fishcage culture station (2.32) and the inlet station (2.05). The fertility criteria of Rawa Pening based on the phytoplankton abundance and P-total of its water is eutrophic going towards hypereutrophic.

The paper industry contributed the environment pollution due to chlor substances. Utilization of alkalothermophilic xylanase enzyme as a biocatalyst in the production of paper may become an environmentally friendly biobleaching alternative. Bacillus halodurans CM1 produces xilanase enzyme that had optimal activity at pH 9 and temperature 70°C. Previous study showed that this CM1 strains has several xilanase genes. The cloning of one of these alkalothermophiic xylanase (alkxyn) gene has been already conducted. This study aimed to clone alkxyn gene that encode alkalothermophilic xylanase enzyme from B. halodurans CM1 into Escherichia coli DH5α. Amplification of alkxyn has been carried out using primers for amplification xylanase 30 kDa. The alkxyn gene fragment was inserted into pGEM-T Easy vector and then transformed into E. coli DH5α. The results showed that the recombinant of E. coli DH5α harboring alkxyn gene from B. halodurans CM1 has been obtained. The sequences analysist based on BLAST showed that alkxyn fragment has homology (99%) with the alkaliphilic xylanase gene from Bacillus sp. 31 which encodes alkaliphilic xilanase (Genebank assession number: JF912895.1).
Keywords: cloning, Bacillus halodurans CM1, xylanase, alkalothermophilic.

Mango is a fruit that is very popular with the community, especially in Semarang. The taste is sweet, refreshing and has a high vitamine content is the reason this fruit has become one of the superior fruit. In the Semarang area there are quite a lot of mango trees with various varieties. These various mango varieties are potential genetic resources that need to be preserved. This study aims to explore the various mango tree varieats that grow in the municipal area of Semarang. Research techniques by exploring in 3 districts are Banyumanik, Tembalang and Gunung Pati. The results showed 14 varieties of mango and the most widely grown varieties by the people in the municipality of Semarang are arum manis and manalagi mango. Some of them are local mangoes, mango cultivation and imported mangoes. Local varieties of mango are only found in very small quantities and have begun to scarce, so it is feared that the supply of mango germplasm is increasingly depleting. Germplasm of local mango plants is important to be preserved as a wealth of genetic resources in the Municipality of Semarang

Green Mustard (Brassica juncea L), Rice washing water, Photosynthetic pigment content, and Vegetative growth.
Mustard plants are a type of vegetable favored by most people. Demand formustard plants continues to increase along with the increasing population and awareness of nutritional needs, but there are obstacles in increasing the production. This is due to the lack of nutrients needed by the mustard plant for its growth. One effort to increase the production of mustard plants is by adding nutrients through fertilization. Fertilizers are divided into two types, namely organic and inorganic fertilizers. However, long-term use of inorganic fertilizers can reduce soil quality and environmental health. One alternative to overcome these problems is to use liquid organic fertilizer in the form of fermented rice washing water. This study aims to determine the effect of 1-day fermented rice washing water and 15-days fermented rice washing water at different concentrations on photosynthetic pigment content and vegetative growth of green mustard plants and find out the best dose of rice washing water for the growth of green mustard plants. The study used a Completely Randomized Design (CRD) of 1 factor with 5 treatments. Each treatment with 4 replications with ordinary water as a control, 1-day fermented rice washing water with the concentration of 50% and 100%, and 15-days of fermented rice washing water with the concentration of 50%, and 100%. The results showed that the watering on 1-day fermented rice washing water with the concentration of 50% and 100% and 15-days of fermented rice washing water with a concentration of 50% had no effect on all parameters but the watering of 15-days fermented rice washing water with a concentration of 100% had an effect on increasing the plant height, number of leaves, leaf area, plant fresh weight, and plant dry weight. The growth of mustard green plants (Brassica juncea L) is best obtained in the treatment of 15-days fermented rice washing water with a concentration of 100%.

Wideng merupakan biota asosiasi hutan mangrove yang sangat penting perannya dalam degradasi serasah mangrove.Wideng mempunyai perilaku membuat lubang pada pematang yang merugikan petani. Sementara pada sisi yang lain, secara fisik hutan mengrove banyak didapati sampah plastik yang berasal dari hulu. Keberadan sampah sangat mengganggu kehidupan bakau maupun biota asosiasinya, terlebih aktifitas pariwisataPerlu dilakukan pengelolaan untuk mengendalikan wideng di tambak, sekaligus mendorong tercapainya estetika kawasan mangrove yang mendukung Ekowisata. Tujuan umum penelitian adalah memanfaatkan sampah plastik sebagai penguat tanggul tambak yang tahan pelubangan wideng (Sesarma sp) untuk mendukung ekowisata mangrove. Hal ini dilakukan dengan mengkajiadanya dinamika spasial populasi Sesarma spp dan makrobentos asosiasi dan tingkat kesukaan substrat (pematang) yang diberi alas berbagai bahan.Kajian observasi dilakukan secara sampling dengan analisis Struktur Komunitas. Adapun kajian pelubangan menggunakan RAL dengan uji lanjut t-test. Hasil sampling makrobentos di jumpai 16 jenis dengan jenis yang umum ditemukan adalah Cerithidea spp, Neries spp dan Sesarma sp.Sesarma sp cenderung mengikuti keberadaan bahan organik, terutama bahan serasah mangrove. Pada perlakuan penguatan pematang menggunakan bahan sampah memperlihatkan pematang yang disisipi bahan serasah cenderung disukai wideng, diikuti bahan sampah plastik dan bahan plastik lembaran. Secara praktek, petambak sebaiknya memungut sampah untuk dimanfaatkan sebagai penguat dengan menyisipkannya pada lumpur bahan tanggul. Prioritas lokasi yaitu di muara tengah dan depan yang banyak ditemukan wideng dan serasah. Mekanisme pelaksanaan penguatan tanggul dapat difasilitasi oleh kelompok tani. Luaran penelitian disamping tanggul menjadi kuat, tidak menarik bagi wideng, kawasan menjadi bersih, juga tidak perluperlu memotong ranting mangrove untuk digunakan sebagai aran (landasan lumpur).

Proteolytic Bacteria, MSG, Protease
The tofu industry in Indonesia is growing rapidly. Tofu liquid waste is usually discharged into the waters and causes water pollution. An efficient way to overcome this problem is to utilize tofu liquid waste. Tofu liquid waste contains proteolytic bacteria that are useful in industry. The increase in bacterial growth is done by adding substances, one of which is the addition of Monosodium Glutamate (MSG). MSG contains glutamate which plays a role in protein synthesis. This study aims to isolate proteolytic bacteria and determine the effect of MSG on the growth of proteolytic bacteria in tofu liquid waste. The research methods included isolation, purification, morphological characterization, calculation of the Proteolytic Index (IP), testing the effect of MSG concentration on growth and protease activity, and data analysis. The MSG concentration used was 0 gr/L; 0.5 gr/L; 1 g/L and 1.5 g/L. The design used was Completely Randomized Design (CRD). The results obtained four isolates with different morphological characteristics. The isolate that had the highest IP value was the fourth isolate of 3,206 and was used for the test. The effect of MSG on growth and protease activity was highest at a concentration of 1.5 g/L at 24 hours. The highest protease enzyme activity was 0.0756 U/mL. The results of the ANOVA analysis showed a significant effect (p<0.05) on the administration of MSG on the growth of the four proteolytic bacterial isolates of tofu wastewater

Monyet ekor panjang (MEP) memiliki peran dalam meregenerasi hutan, salah satunya melalui aktivitas makan. Resort PTN Tapos merupakan salah satu habitat MEP yang lokasinya berdekatan dengan pemukiman warga sehingga dapat mempengaruhi aktivitas makan MEP. Penelitian ini bertujuan untuk mengetahui aktivitas makan MEP yang meliputi aktivitas yang sering dilakukan, aktivitas makan berdasarkan waktu, usia, serta jenis pakan yang dimakan oleh MEP pada dua lokasi pengamatan, yaitu Blok Hutan Pasir Beunyeng (PB) dan Pasir Koja (PK). Pengamatan aktivitas MEP menggunakan metode instantaneous scan sampling dan disajikan dalam bentuk persentase. Aktivitas makan MEP yang teramati di Blok PB sebesar 10,92%, sedangkan di blok PK sebesar 21,72%. Aktivitas waktu makan MEP di blok PB tertinggi pada sore hari 71,43%, sedangkan di blok PK tertinggi pada pagi hari 76,92%. Aktivitas makan MEP berdasarkan usia di blok PB tertinggi pada remaja 53,85%, sedangkan di blok PK tertinggi pada remaja 41,07%. Kelompok MEP di blok PB lebih memilih jenis pakan daun Calliandra sp. sebesar 76,92%, sedangkan MEP di blok PK lebih memilih jenis pakan daun Bambusa sp. sebesar 39,29%. Sumber pakan MEP di habitatnya terus berkurang disebabkan peralihan fungsi lahan sehingga pergerakan MEP cenderung memasuki perkebunan penduduk sekitar.

Virgin Coconut Oil (VCO) and olive oil have been widely applied in the field of health. Saturated fatty acid content of VCO dominates the total fatty acid content of about 85%. Olive oil contains a lot of oleic acid, which is one type of unsaturated fatty acid (mono-unsaturated fatty acid). This study aimed to analyze the kidney microanatomy rat (Rattus norvegicus) after supplementation with VCO and olive oil in the feed. This study used 25 rats were divided into five treatment groups, P1 was the control group, P2 was a group with VCO 5 mL / kg feed, P3 was a group with VCO 10 mL / kg of feed, P4 was a group with olive oil 5 mL / kg feed and was a group with olive oil 10 mL / kg of feed. The results of ren weight and diameter rat glomerular analyzed using analysis of variance (ANOVA). Research design used was completely randomized design with five treatments and five replication. Results of studies on weight ren showed no significant difference between treatments P2, P3, P4 and P5 to the control (P1). The results of the glomerular diameter shows there is significantly difference between the diameter of the glomerulous treatment P2 and P3 with control (P1), while in treatment P4 and P5 are not significantly different from the control so that it can be concluded that the administration of the VCO and olive oil at various concentrations do not give rise to different responses to weight ren. Olive oil does not increases glomerular diameter white mice, while VCO at a dose of 5 mL / kg feed and 10 mL / kg of feed can increased glomerular diameter mice.
Keywords: ren weight, glomerular diameter, Virgin Coconut Oil (VCO), olive oil.

A massive death of vannamei shrimp (Litopenaeus vannamei Boone.) due to Infectious Myonecrosis Virus (IMNV) infection has occurred in Indonesia recently and still cannot be eradicated efficiently. The fast reproduction of IMNV depends on the RdRp gene that encodes for RNA polymerase. Genetic characterization of IMNV RdRp gene from Indonesia is important in order to compare with other IMNV to find out genetic variation as a base for combating this virus. IMNV-infected vannamei were taken from major aquaculture region in Indonesia (Lampung, Gresik and Pontianak). RNA polymerase coding genes (12 and 13 region) from infected vannamei were amplified using RT-PCR with appropriate primer. Amplification products were sequenced and the results were analyzed using BioEdit 7.1.3.0, ClustalW2, CLC free workbench 6.6.2. and ClustalX programs. Results showed that homology value of IMNV RdRp gene from Lampung and Gresik were 98,04-9958% compared with IMNV from Brazil (Acc. No. AY570982). Amino acid analysis revealed homology value of IMNV RdRp gene from Lampung and Gresik were 100% and 99.04% compared with IMNV from Brasil. IMNV RdRp gene from Pontianak cannot be analysed due to low quality of RNA.
Key words: vannamei, IMNV, RdRp, genetic characterization

Insect Night, Light Trap (red, yellow, blue and white), Liwa Botanical Garden.
Insects are invertebrate animals with diversity and have a high adaptability. Insects have properties that are very sensitive to light, especially night insects. Night insect species in the Liwa Botanical Garden (KRL) have not been identified. This research was conducted from October to November 2019 in the Liwa Botanical Garden, West Lampung Regency. The purpose of this study was to determine the effect of the color of the lights (red, yellow, blue and white) on the presence of night insects on KRL. This research was conducted using the Purposive Sampling method using red, yellow, blue and white light. The insects that were caught were identified in the Zoology Laboratory of the Faculty of Mathematics and Natural Sciences Unila and analyzed descriptively based on morphological similarities with the book Borror et al., (1992). The data obtained were analyzed using the ANOVA test using Minitab 19. The results of this study showed that in the Araceae area of the Taman Liwa Botanical Garden the blue light traps caught a maximum of 457 night insects while the red light traps caught the night insects with the least number 19 tail. This study also showed that light intensity correlated with the number of night insects obtained.

Industrial waste contributes the heavy metals pollution in the environment, especially in the water. One of the heavy metals that pollute the environment is lead (Pb). Lead is a substance that is harmful to organisms, especially humans, both adults and children. Solutions to tackle Pb pollution isby remediation process. Physical and chemical remediation methods usually costly and ineffective. One of the alternative methods which is used is the bioremediation uses microalgae or called as phycoremediation. One of microalgae which is used as agents of phycoremediation is Spirulina platensis Geitler because it’s easily cultured and it’s abundant in nature. This study aims to assess the population growth and the percentage reduction of Pb after inoculated with the use of Spirulina platensis Geitler. The method which is to cultivate S. platensis Geitler in brackish watermedia with a salinity of 15 ppt which have been added Pb with a concentration of 1 mg, 3 mg, and 5 mg for 8 days and observed the population and the percentage reduction of Pb heavy metals. Environmental factors such as temperature, salinity, pH, light intensity are conditioned to remain stable. After 8 days of research, study was able to reduce Pb. Each treatment has different concentrations decrease. Treatment Pb 1 mg of 0.949 into 0.603 mg / L; Pb 3 mg of 2.894 to 2.46 mg / L; and Pb 5 mg of 4.88 to 4.31 mg / L, with each percentage decline of 36%, 15% and 12%. The Pb 3 mg treatment has higher cell population (129.367 cell / ml) than control (106.600 cell/ml) while 1 mg and 5 mg treatment has 93.700 cell / ml and 93.500 cell / ml.

Bryofauna is all of the animal life which associated with moss. Actually, biodiversity of bryofauna have not been studied much in Indonesia. Research on community structure of terrestrial microarthropod bryofauna has been done in three different altitudes in the tropical zone of the Ungaran Mountain, Semarang, Central Java. The objective of this study is to compare community structure of bryofauna contained in three different altitudes in the tropical zone. The research was conducted from April to November 2012. Sampling was carried out at 3 stations with the different heights that are the station I with an altitude 750 m asl, the altitude of the station II with an altitude 980 m asl and the station III with an altitude of 1100 m asl. Sampling was done purposively using square plot method. Bryofauna identification was conducted in Ecology and Biosistematics Laboratory University of Diponegoro and Entomologi Laboratory of Zoology Departement Indonesian Institute of Sciences. The results shows that the tropical zone have5 classes, 16 orders and 31 suborders/family of bryofauna. Mesostigmata and Oribatida was the dominant taxa at all heights except at an altitude of 980 m asl, Oribatida was categorized as subdominant. Diversity of bryofauna at different heights shows that decreasing diversity patterns, along with the increasing altitude. In general, the distribution of bryofauna at different heights is quite spread evenly with the flattening index values betweens 0.84 to 0.94. Bryofauna taxsa richness and diversity of bryophytes at different heights in the tropical zone showed the same pattern fluctuated. Taxa group which play a role as predator are taxa that the most abundant in the tropical zone of the Ungaran Mount.

Karimunjawa Jepara is a region with high diversity, including the diversity of seaweed. Brown seaweed is potential marine organisms due to their ability to produce enzymes, pigments, and bioactive compounds. This ability makes brown seaweed one of the potential biological agents from the marine to be developed in the industrial field. However, most of these substances may not be produced by seaweed itself, but cooperation with microbes or even by bacteria or symbiotic fungi. Secondary metabolites which are pharmaceutical, enzyme, and cosmetic sources can be produced by microbial associan. The purpose of this study was to carry out phylogenetic analysis and morphological characterization of colonies from pigmented yeast associated with Sargassum sp. The results of the phylogenetic analysis indicate that isolates of KY 3 have 100% relative similarity with Cystobasidium oligophagum.

Peta Batimetri Danau Rawapening
Soeprobowati, Tri Retnaningsih
Lake has an important function as source of water; maintain biodiversity; source of protein; manage toxicity; device to reduce river flooding; source of groundwater; device climate; transportation and touris; medium; and for cultural and religion activities. Semi natural lake of Rawapening has function for hydroelectricity power, irrigation for agriculture, fisheries, and tourism. For maintaning those functions, lake batimetric map is required for limnological study as well as for basic informasi for development lake management. However, there is no batimetric map of Rawapening Lake after1976 lake’s sketch by Goltenboth. Therefore, this survey was conducted in order to update batimetric map of Rawapening. On August 16th, 2008, echosounding was donecfross section and lake edge every 30 second. Recorded data on the GPS then interpolated to the lake depth form in every dot of echosounding.The deepest part of Rawapening Lake was 18 metres, around Bukit Cinta spring. Comparing to Goltenboth sketch, the Rawapening Lake depth was not quite change. North West part of the lake remain has 2-4.7 metres depth. However, based on sedimentation rate, the shallowness lake was very sharply, and predicted that in 2021 Rawapening Lake will full of sediment. Maintaning lake depth is a must to maintain lake’s function.

The existence of these wastes can affect the quality of the waters and lives therein. This study aims to determine the quality of the waters by assessing the structure of the macrobenthos community temporally and spatially which are related to the physical-chemical parameters of the water. The data collection of macrobenthos and substrate waters were carried out at 5 station considered as represent variety of waters bodies in Sayung. Samples were taken 2 times, in dry season and rainy seasons. Water parameters measured including DO, salinity, pH, turbidity, and temperature, while sediments are analyzed for the grain size of sediment and organic matter content. The results from macrobenthos analysis found 20 species. The most commond macrobentos found Metapenaeus monocerus, Cerethidea cingulata,Telescopium telescopium and Sesarma sp. Macrobenthos diversity index ranges from 0.59 to 1.76; Evenness index ranges from 0.78 to 0.96; and the dominance index ranges from 0.19 to 0.59. Diversity index value include the moderate criteria, which indicates a disturbance in Sayung waters. The results of multiple linear regression test showed that DO-silt parameter has a strong influence on the abundance of macrobenthos. The abundance of species Cerithidea cingulata at the research site can be used as bioindicators of contamination organic matter. Generally these waters still supports aquaculture

PGPR, late blight disease, Phytophthora infestans, Ngudi Makmur
Late blight disease caused by Phytophthora infestans, is probably the single most important disease of potatoes worldwide. Infected plants were quickly killed and were difficult for replanting, causing significant losses for the growers. Various control methods were examined including the use of biocontrol agents of PGPR. The research objective was to determine the ability of PGPR product from Ngudi Makmur farmer group local to delay late blight disease incidence on potato plants in the field. The in vivo experiment was carried out at potato land area located at Kledung Sub District, Kledung District and Temanggung Regency. Randomized Block Design (RBD) with five treatments was applied with five treatments each of which was placed in a different plot and each plot was filled with 40 plant treatments. On the first plot, no treatment was given (P1); the second plot was given chemical fertilizer (P2), the third plot was supplemented with PGPR one dose (P3), the fourth plot was PGPR two dose (P4), and the last was the fifth plot treated with GA hormone (P5). Result of the research showed that application of PGPR could delay disease intensity until 14 days. These antagonist could be used as biological agents initials to control leaf blight disease. There was an improvement in the quality of potato tubers harvested with the PGPR application compared to controls too.

apoptosis, cytotoxic, HeLa cell, Oryza sativa L. ‘Sembada Hitam’
Black rice (Oryza sativa L.) contains various phenolic compounds such as anthocyanins which act as antioxidants. Antioxidants inhibit cell proliferation and induced apoptosis of cancer cells as well as protect cells from damage that triggers cancer. 'Sembada Hitam' is a new cultivar of black rice in Indonesia that has not been studied for its anticancer potential. This study aimed to study the cytotoxic activity and apoptosis induction of the ethanolic extract of black rice (Oryza sativa L. 'Sembada Hitam') bran against HeLa cells. The method used was the cytotoxicity test with the MTT assay and the apoptosis test with the AO-PI double staining method. The test used various concentrations of black rice bran extract, DMSO as solvent control, and doxorubicin as a positive control for 24 and 48 hours. Data analysis was performed using one-way ANOVA (p = 0.05) followed by the Tukey HSD test. The results showed that ethanolic extract of black rice 'Sembada Hitam' bran has no cytotoxic activity against HeLa cells (p > 0.05). Moreover, extracts at the concentrations of 250 and 500 µg/mL only induced apoptosis of HeLa cells by 11.62 ± 0.50 and 11.49 ± 9.88% respectively. These results indicate that the ethanolic extract of black rice 'Sembada Hitam' bran has no potential to be developed as an agent for cervical cancer therapy.

Availability of drugs in Indonesia is still limited by the high prices of drugs due to on the imported raw materials that reaches 95%. Developing antibiotic raw materials can be achieved by increasing of penicillin G production, which is the raw material for the formation of semisynthetic penicillin derivatives through the production of 6-aminopenisillanic acid (6-APA). One of the important enzyme in the penicillin G biosynthesis is Isopenisilin N Synthase (IPNS) that encodes by pcbC gene on Penicillium chrysogenum. This study aimed to obtain a recombinant of pcbC gene fragments that is inserted into pPICZA plasmid. Amplification of pcbC gene used pcbC-F and pcbC-R primers. The pcbC gene fragment was inserted into pPICZA vector and then transformed into TOP 10 F’. The results showed that the recombinant of the pcbC gene fragment from P. chrysogenum has been obtained. Analysis of DNA sequences using the BLAST program showed that the pcbC gene fragment has high homology (99%) with the pcbC gene from P. chrysogenum Wisconsin 54-1255 and P. chrysogenum AS-P-78 which encodes IPNS

Brotowali plant, α-amylase, ethanol extract
Brotowali plant (Tinospora crispa L.) is a traditional Indonesian medicinal plant which has many benefits including for diabetes drugs. Diabetes mellitus (DM) is a metabolic abnormality caused by an increase in blood sugar levels. The purpose of this study was to determine the activity of α-amylase inhibitors of Brotowali (T. crispa L.) ethanol extract of plants. Extraction is done by maceration followed by evaporation. The extract obtained was tested for α-amylase inhibitor activity. The α-amylase inhibition test is based on the breakdown of starch substrates into maltose and glucose which is then determined by spectrophotometer after administration of DNS. Tests are carried out on controls and samples. As a substrate is 0.5% starch solution in 100 ml of sterile aquades. The reaction mixture was incubated 25 ° C for 10 minutes. The reaction is stopped by adding 2 ml of 3,5-dinitrosalicylic acid (DNS). All the mixed solutions are then heated to 100 ° C for 5 minutes and allowed to cool. The change in color of the solution is then measured for its absorbance at a wavelength of 540 nm. As a comparison used a control test that did not use extract samples. The results of α-amylase inhibitor activity test showed that ethanol extract with a concentration of 1000 μg / mL had the highest inhibitory activity value of 95.06% compared to extract concentration of 500 μg / mL, 250 μg / mL, 125 μg / mL and 62.5 μg / mL. The results of testing the effect of substrate concentration showed that 0.5% starch concentration had the highest inhibitory value of 9.52% compared to 2%, 1% and 0.25% concentrations

Bledug Kuwu, Grobogan, halophilic, bacterial morphology
Bledug Kuwu is an area that has a fairly high salt content, this is caused by sea water trapped in the sedimentation process around the 18th century. Microorganisms that are able to live in extreme areas tend to have typical metabolic activities and can be utilized in industry. The purpose of this study was to characterize microbiologically, bacteria isolated from Bledug Kuwu, Kradenan District, Grobogan Regency, Central Java. The method used in this study was isolation on LB + NaCl media with NaCl levels of 10%, 12.5% and 15%. Characterization was done by Gram staining and motility test. The results obtained in samples from 3 sources, namely teak water, salt water and mud water, obtained 8 pure isolates. The seven isolates have the ability to grow optimally at 10% NaCl concentration so that these bacteria can be classified as moderate halophilic bacteria with the majority of species being coccus, Gram positive, and non motile.

Forests are ecosystems that have very potential natural resources, including storing high genetic resources. One of the things that threatens the decline of genetic resources in the forest is the presence of invasive species. This study aims to determine the species of invasive plants and their abundance in the Penggaron tourism forest of Ungaran Regency, Central Java. The research method was carried out by exploring the entire forest area through the path. The results of the study showed that 13 species of invasive plants were included in 7 families. The most number of invasive plants from the Poaceae family include 5 species : Axonopus Compressus, Cynodon dactylon, Pennisetum purpureum, Paspalum conjugatum and Eleusine indica. The highest relative abundance was Eleusine indica and was followed by Synedrella nodiflora, Elephantopus scaber and Paspalum conjugatum. The species of invasive plants, especially the abundant ones, need to be controlled by the population so as not to threaten native plants and cause environmental degradation in Penggaron tourism forests.
Key word : Invansive plant, Penggaron tourism forest, genetic resources.

Yuliana, Rida
Kusdiyantini, Endang
Izzati, Munifatul
Penelitian ini bertujuan untuk mengeksplorasi manfaat umbi dahlia dalam bentuk tepung umbi dan ekstrak inulin sebagai substrat untuk memproduksi FOS. Produksi FOS berlangsung secara mikrobial enzimatis dengan bantuan khamir Kluyveromyces marxianus DUCC-Y-003. Pengkulturan khamir pada media kultur berlangsung selama 60 jam dan dilakukan pengukuran tiap 6 jam. Pengukuran tersebut meliputi pertumbuhan khamir, kadar fruktosa medium dan kadar total gula medium. Penentuan FOS dilakukan dengan cara mengukur nilai derajat polimerisasi (DP). DP merupakan hasil perbandingan antara kadar total gula dengan kadar fruktosa pada media kultur. DP FOS berkisar antara 2-10 dan FOS komersil dengan DP 3-5. Penelitian menggunakan Rancangan Acak Kelompok Faktorial (RAKF). Perlakuan terdiri atas S1D1 (substrat tepung, dosis 1 g), S1D2 (tepung, 3 g), S1D3 (tepung, 5 g), S2D1 (ekstrak inulin, 1 g), S2D2 (ekstrak inulin, 3 g), S2D3 (ekstrak inulin, 5 g). Hasil penelitian menunjukkan bahwa pertumbuhan khamir tertinggi pada perlakuan penggunaan ekstrak inulin dengan dosis 1 gram, dan pertumbuhan terendah pada perlakuan penggunaan tepung dengan dosis 5 gram. Pada masing-masing perlakuan, menghasilkan produk FOS dengan nilai DP yang beragam selama waktu inkubasi 60 jam, hanya perlakuan S2D1 (ekstrak inulin, 1g) yang sudah menghasilkan ketiga jenis FOS komersil dalam waktu inkubasi 60 jam. Pada perlakuan S2D1, produk 1-kestosa dihasilkan saat inkubasi 42 jam, produk nystosa saat 48 jam dan produk fruktofurasylnystosa saat 60 jam. Kesimpulan hasil penelitian adalah perlakuan S2D1 paling efektif dalam menghasilkan FOS selama waktu inkubasi 60 jam, sedangkan perlakuan lain dapat menghasilkan FOS yang sama jika lama waktu inkubasi diperpanjang.

Currently local ducks are generally quite difficult to find in a big farm in Inonesia, including Tegal ducks. Tegal ducks is one of the genetic resources native to Indonesia with it’s advantages in terms of high and large egg production. Conservation and development of local ducks have strived to maintain our existence of Indonesian livestock germplasm. If such information is not superior to native species exist, the opportunity to increase his lead further also getting smaller. Tracking the mitochondrial COI gene DNA of Tegal ducks may underlie the process of an organism's genetic characterization. Information about Tegal duck mitochondrial DNA has not been done. The information obtained can be used for optimization of duck products native to Indonesia both in physiological aspects, phylogeny and genetic engineering. The research method used in this research is tracking COI gene data from Gen Bank with the programs Clustal X and Genedoc. Tracking then continued using universal primers HCO and LCO. The results of the data followed up with the isolation and amplification of COI gene mitochondrial DNA as well as the optimization of PCR conditions. The results showed mitochondrial DNA COI gene Tegal ducks were amplified with primer LCO obtain DNA fragments of length less than 250 bp.

Bacillus thuringiensis, Nematicidal Cry Genes, SDS-PAGE, PCR, Transformation, Restriction Digest
Cry proteins of Bacillus thuringiensis have been successfully used as biopesticides and transgenic crops throughout the world. However, resources against the most serious agricultural pathogens, plant root-knot nematodes, are limited. Nematicidal Cry proteins produced by Bacillus thuringiensis (Bt) are used for effiecient pest control. Cry 5, Cry 6, Cry 21, and Cry 55 were known to have nematicidal activity. In the present study, 80 Bt isolates from diverse locations in Thailand have been investigated for their nemeticidal cry gene content. Bt isolates were screened through Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE), Polymerase Chain Reaction (PCR), ligated into the cloning vector PJET 1.2/blunt, transformed into Escherichia coli DH5ɑ, and diagnostic restriction enzyme digest for the presence of nematode-active cry genes. Of 80 Bt Thai isolates, 24 isolates (30%) have 54-kDa protein which is similar with the molecular weight of Cry 6 protein and 5 isolates (6%) have ±45 kDa protein which is similar with the molecular weight of Cry 55protein. Only one Bt isolate (Bt 32) was suspected to be positive for the presence of cry 6 gene.

Antimicrobial peptides, Pediococcus pentosaceus, Vitamin B Complex
Both eukaryotic and prokaryotic organisms can produce antimicrobial peptides (AMPs) which function as a self-defense mechanism against other harmful organisms in the same ecological niche. Pediococcus pentosaceus is a species of Lactic Acid Bacteria (LAB) capable of producing AMPs in the form of bacteriocins and bacterocin-like inhibitory substances. The compounds it produces have received Generally Regarded as Safe status by the Food and Drug Association (FDA) and have potential as biological preservatives in the food sector. The production of these compounds can be influenced by environmental factors and growth medium of producing bacteria, so that optimization studies for the production of bacteriocin have been developed, in order to obtain optimal its activity. Vitamin B Complex is one of the growth factors needed by living things including bacteria to support their metabolism. This study aims to determine whether the addition of vitamin B complex affects the production and activity of AMPs from P. pentosaceus. Vitamin B Complex concentrations of 0 ppm, 0.1 ppm, 1 ppm and 10 ppm were added to the production medium of P. pentosaceus. Cell-free supernatants were harvested by centrifugation, then their activity was tested against Bacillus cereus and Eschericia coli using the Kirby Bauer method and analyzed using one way ANOVA parametric statistical test with a significance level of 0.05 and Duncan's post hoc test. The results showed that the addition of vitamin B complex was not significantly different to the activity of AMPs compounds, but in higher concentrations could reduce the activity of these compounds.

Izzati, Munifatul
Salah satu dampak negatif modernisasi dan industrialisasi adalah pencemaran lingkungan. Perairan merupakan salah satu lingkungan yang paling terbebani bahan pencemar karena banyaknya limbah rumah tangga maupun industri yang akhirnya masuk ke lingkungan perairan. Salah satu bahan pencemar perairan yang paling membahayakan adalah logam berat karena bersifat non-biodegradable. Oleh karena itu perlu upaya penanganan maupun pencegahan terhadap bahan pencemar tersebut. Pengolahan limbah secara fisiko-kimiawi dinilai mahal, menurunkan biodiversitas, banyak lumpur yang dihasilkan, dan kurang efektif pada konsentrasi logam di bawah 50 mg/l. Bioremediasi merupakan salah satu metode perbaikan lingkungan yang lebih ramah lingkungan karena menggunakan agen hayati seperti bakteri, jamur, protista, dan tanaman. Chlorella vulgaris Beijerinck merupakan mikroalga bersel satu yang banyak tumbuh di perairan tawar dan laut, telah dimanfaatkan masyarakat sebagai bahan pakan, suplemen, biofuel dan bioremediasi. Penelitian ini bertujuan untuk menguji potensi C. vulgaris sebagai agen bioremediasi terhadap cemaran logam berat Cd dan Pb skala laboratorium. Penelitian menggunakan Rancangan Acak Lengkap (RAL). C. vulgaris ditumbuhkan dalam media kultur yang telah diberi pupuk Walne selama 76 hari. Media kultur ditambah ion logam Cd dan Pb dengan 3 konsentrasi yang berbeda yaitu 1 ppm, 3 ppm, dan 5 ppm, masing-masing 3 kali ulangan. Medium kultur tanpa penambahan logam dianggap sebagai kontrol. Kandungan logam berat dalam medium dan dalam sel C. vulgaris diukur dengan AAS. Hal yang diamati dalam penelitian ini adalah pola pertumbuhan populasi C. vulgaris, persentase penurunan logam Cd dan Pb oleh C. vulgaris, besarnya akumulasi logam dalam C. vulgaris, serta nilai Bioconcentration Factor (BCF). Berdasarkan penelitian tersebut terbukti bahwa C. vulgaris terbukti mampu menurunkan konsentrasi ion Cd dan Pb dalam perairan. Prosentase penurunan konsentrasi ion Pb dalam media kontrol, 1 ppm, 3 ppm, dan 5 ppm berturut-turut 70%, 80%, 62%, dan 52% sedangkan dalam media Cd pada konsentrasi serupa berturut-turut 67%, 79%, 56%, dan 51%. C. vulgaris mampu mengakumulasi Cd lebih besar daripada Pb. Berdasarkan nilai BCF terhadap Cd maupun Pb, C. vulgaris tergolong akumulator logam.

Paper waste, growing media, mycelium, Pleurotus ostreatus
Paper waste is an organic residual that has not been widely utilized and its existence around us. The high cellulose content in paper waste allows it to be used as a media for cultivating white oyster mushrooms. This aims to compare the speed of mycelium propagation from different concentration of paper in each growing medium. The study used a Completely Randomized Design (CRD) with six treatments and five repeattation. The treatment used is the difference in the composition of 0% paper waste media (control); 20% of paper waste; 40% of paper waste; 60% of paper waste; 80% of paper waste; and 100% of waste paper. The data were obtained from six time observations in the form of mycelium propagation (cm)and tested with anava. The results were not significant at 1,65 using correcttion factor 2,53. Mycelium propagation speed was influenced by environmental factors such as temperature, light intensity, humidity, and air circulation.

Chromosomes and Mitotic Cell Division Phase In Onion Roots After 24 Hours Acetoorcein Soaking Time
Kusumaningrum, Hermin Pancasakti
Lunggani, Arina Tri
Nurhakim, Muhammad Amal
Onions (Allium cepa) are usually used in vitro to assess effect of chemical subtances by allowing developing roots to come into contact with substances to be tested. Acetic orcein staining of onion chromosomes has remained a standard method of preparation. However, aceto-orcein stain is corrosive and poisonous chemical substances since it containing oxidising agents such as organic peroxides, the toxic substances which are are cyanides, acid corrosives agents, and also radioactive substances. This research study mitotic activity in the roots of onion plants to determine the effects of soaking time of aceto orcein dye on actively dividing root cells. A series of several root tip from each bulb was harvested were soaked in 1, 3 and 24 hours on aceto-orcein stain and processed further for cytological studies by the aceto-orcein squash technique. The research was carried out to study the effect of to mitotic index and chromosomal aberration on onion root. It will determine the percentage of cells that are undergoing mitosis. The squash techniques were used to observe mitosis in the tip of onion root cells during actively mitotic division cells time. Mitotic divisions occur in several phases, consist of prophase, metaphase, anaphase, telophase and interphase. Experiment were repeated six times for every soaking time. The data was analyzed by using T-Test. The result showed that various duration of soaking time significantly influenced the reduction of mitotic index value. The lowest mitotic index on glyphosate concentration 100 ppm i.e. 10. 73% and 7.19% for the duration of soaking time 3 and 6 hours. The highest mitotic index on glyphosate concentration 0 ppm i.e. 37.71% and 32.76% for the duration of soaking time 3 and 6 hours. The result also showed that the chromosomal aberration were increased significantly. The lowest chromosomal aberration obtained i.e. 2.55% and 2.96% for the duration of aceto orcein soaking time 1, 3 and 24 hours. The highest chromosomal aberration obtained i.e. 21.71% and 36.26% for the duration of soaking time 1,3 and 24 hours. The type of chromosomal aberration were abnormal prophase, stickiness, bridge, abnormal anaphase, clumping chromosome, c- metaphase, change of nucleous shape and size.
At 72h, their cytotoxic effects on the root tips showed strong growth retardation in high concentrations of all the wastewaters. Compared to the control, treatment with the wastewaters resulted in root growth inhibition with EC50 values of 35, 50 and 62% for bottling, rubber and brewery effluents respectively, and decrease in mitotic index with increasing concentration for all samples and these were statistically significant (p<0.05). Chromosomal aberrations induced in the onion root tip cells were mostly sticky chromosomes and bridges. Chromosomes with disturbed spindles and fragments were also present in appreciable amounts. Based on the EC50 values, the bottling wastewater was most toxic, followed by rubber effluent while effluents from the brewery were least toxic. The findings in this study indicate that there are toxic chemicals present in the wastewaters which are responsible for the observed genotoxic effects on the onion root tip cells. The study also reveals that the Allium test is a useful and reliable tool for the genotoxicity screening of industrial effluents which could be employed by environmental managers before these effluents are finally discharged into the environment.

Penyimpanan telur, pH telur, Indeks Kuning Telur, Indeks Putih Telur
Puyuh Jepang (Coturnix coturnix japonica L.) banyak dibudidayakan untuk diambil telurnya karena produktivitas telur yang tinggi. Nilai gizi telur puyuh tidak kalah dengan telur unggas lain, sehingga dapat menambah variasi dalam penyediaan sumber protein hewani. Telur merupakan salah satu bahan makanan yang hampir sempurna. Bahan makanan ini mengandung zat gizi lengkap antara lain protein, lemak, vitamin dan mineral. Telur segar yaitu telur yang baru diletakkan oleh induk disarangnya, mempunyai daya simpan yang pendek. Salah satu faktor yang menyebabkan rusaknya telur adalah lama waktu penyimpanan . Penelitian ini bertujuan untuk menganalisis kualitas telur puyuh berdasarkan pH Telur, nilai Indeks Kuning Telur (IKT), Indeks Putih Telur (IPT) setelah perendaman dengan air kapur. Sampel yang digunakan adalah telur puyuh yang diambil pada hari kedua peneluran. Digunakan Rancangan acak lengkap dengan 5 kelompok perlakuan yaitu P1 kelompok telur,diamati pada hari ke 2. P2 kelompok telur disimpan dan diamati pada hari ke 16. P3 kelompok telur direndam pada air kapur selama 1 menit, disimpan dan diamati pada hari ke 16. P4 kelompok telur disimpan dan diamati pada hari ke 30. P5 kelompok telur direndam pada air kapur selama 1 menit, disimpan dan diamati pada hari ke 30. Data yang diperoleh dianalisis menggunakan ANOVA dengan taraf signifikansi 5%. Hasil penelitian menunjukkan semua variabel penelitian menenunjukkan penurunan seiring dengan bertambahnya waktu penyimpanan. Penurunan kualitas disebabkan faktor lamanya penyimpanan yang menyebabkan perubahan kondisi telur.

Plankton is organisms that had an important role in water as natural feed of fishes and as an indicator. This study aimed to identify water quality which was suitable for fish cultivation reviewed from physics-chemicals parameters of water and its saprobic status in Tambak Lorok Tanjung Mas Kota Semarang. Sampling were take based on 5 stations that could represented from plankton variety of condition water stability . Plankton samples were by using net plankton number 25, then preserved with alcohol 70% and formalin 4%. Variables of ponds water quality measured were temperature, salinity, dissolved oxygen, pH, turbidity, N concentration, and Pb content. Identification of planktons used SRC method under microscop. The result of plankton analysis in Tambak Lorok water showed 42 phytoplankton species, the commonly species found are Coscinodiscus centralis, Coscinodiscus granii, Gyrosigma sp., Navicula radiosa, Pandorina sp., and Melosira sp. Meanwhile, zooplankton found was 22 species with common species are Cyclops, Harpaticoida, Tricodesmium evythraeum, Brachinus plicatilis, and Lensia subtilis. Phytoplankton diversity index are 0.057-0.367 and equity index are 0.025-0.176. Zooplankton diversity index are 0.247-0.360 and equity index are 0.157-0.201. This indices showed that there were low level of species diversity and community stability, dominance since the species occurred. Measurement of water quality variables indicated that Tambak Lorok had been contaminated and needed a preliminary management before d be used as fish cultivation ponds, because the analysis result was not appropriate with Government water quality regulation.

Kemampuan Indonesia dalam memenuhi kebutuhan beras nasional sangat penting. Akan tetapi, usaha pemenuhan kebutuhan beras ini tidak selamanya berjalan dengan lancar karena terganggunya produktivitas padi. Salah satu penyebab turunnya produktivitas padi di Indonesia karena adanya serangan serangga hama. Beberapa kendala yang menyebabkan gagalnya petani dalam mengendalikan serangga hama karena petani masih belum melakukan identifikasi serangga hama dan gejala serangan dengan baik. Penelitian yang dilaksanakan akhir tahun 2012 ini yang berlokasi di Lahan Persawahan Padi Dataran Tinggi Desa Sukawening, Kecamatan Ciwidey, Kabupaten Bandung, Jawa Barat bertujuan meng inventarisasi dan mendapatkan nilai keragaman jenis serangga hama pada tanaman padi. Penangkapan serangga hama yang dilakukan dengan menggunakan perangkap kuning, perangkap jaring dan perangkap cahaya. Hasil penangkapan serangga diidentifikasi di laboratorium. Indeks keragaman serangga dianalisis dengan menggunakan perhitungan Shannon- Weinner. Serangga hama yang dominan diperoleh pada fase vegetative yaitu Scirpophaga incertulas, Thaia oryzivora, dan Orselia oryzae. Serangga hama minor diperoleh yaitu Dicladispa armigera, Leptispa pygmaea, dan Melanitis ledaismene. Serangga hama yang dominan diperoleh pada fase generative yaitu Leptocorisa acuta, Scirpophaga incertulas, dan Thaiaoryzivora. Serangga hama minor diperoleh yaitu Nilaparvata lugens, Sogatella furcifera, dan Cofana spectra. Indeks keragaman serangga hama yang diperoleh pada ketiga lahan percobaan ada diantara sedang hingga tinggi.Pada fase vegetatif indeks keragaman tertinggi sebesar 4,74 pada pengamatan ke 6 dan terendah pada pengamatan ke 1 sebesar 2,22. Pada fase generatif indeks keragaman tertinggi pada pengamatan ke 9 sebesar 4,86 dan terendah pada pengamatan ke 12 sebesar 1,37.

In mature oil palms, rat attacks fruit bunches, causing significantly reduction in the potential yield and the quality of oil palm fruit bunches. Rat is also known to consume the post anthesis male flowers which act as the breeding sites for the eggs and larvae of Elaeidobius kamerunicus pollinator beetle. Indirectly, the pollinator beetle population can be reduced in high rat infestation area, affecting the pollination and increasing the percentage of parthenocarpic fruit bunches. The barn owl (Tyto alba var. javanica) is a rat biological control agent in the oil palm plantations. The study conducted at PT. Mustika Sembuluh in Central Borneo shows that barn owl (T. alba) population is significantly correlated with both rat attacks and parthenocarpic percentage of oil palm fruit bunches in oil palm plantation

Rice stem borer is a main pest of paddy rice in Central Java. The main rice stem borer are yellow rice borer, Scirpophaga incertulas Walker, and white rice borer, S. innonata Walker. Other species are pink borer Sesamia inferens Walker, striped rice borer Chilo suppressalis Walker, dark-headed rice borer, C. polychrysus Meyrick, and glossy rice borer, C. auricilius Dudgeon. Besides rice stem borer, there are many other insect which are potential as rice pest, i.e., grasshopper, rice ear bug, brown planthopper, etc. Organic agriculture in Central Java have not been applied yet, hence there is still lack of information, including species diversity information and abundance of rice stem borer population and other potential insect pest on rice. Species diversity and population abundance of rice stem borer and other potential insect in organic rice ecosystem differ with the inorganic one. The objective of this research is to study species diversity and abundance of rice stem borer population and other potential pest in organic rice ecosystem. The study was conducted in organic rice of Bakalrejo Village, Susukan Sub district, District of Semarang. Species diversity and population abundance was analyzed using Shanon-Wiener’s species diversity index (H’), population abundance index (Di), and population evenness index (e). Pattern of species diversity, population abundance, population evenness were temporally analyzed using population dynamic curve. Sampling of species diversity and population abundance was performed during a crop planting season with twice of sampling frequency. The result shows that rice stem borer found were yellow rice borer with its population fluctuated temporally and pink rice borer with its population were few and scarce. The highest diversity found during rice generative phase until ripen and decline in line with the age of rice. Species diversity index in vegetative phase was below 2, while during generative phase until ripen increased above 2. Insect population abundance declined in the end vegetative phase and increased in the beginning of reproductive phase until ripen phase. Population evenness index in all growth phase of rice were relatively high and similar.

Hemidactylus frenatus has 2 color morph, those are dark morph and light morph. This gecko also has the ability to change it’s body color from one morph to another. This ability is usually associated with thermoregulation effort or camouflage for defense. This research attempts to assess the camouflage of the house gecko on various habitat type (building and garden) that exist on UGM campus. By employing CBIR method, it is found that this gecko has high similarity with it’s surrounding, either on the light background (building) or dark background (garden). This is shown by the Euclidean distance value at 0.36 on the gecko that lives on the buildings, and 0.13 on the gecko that lives on the garden. According to the observation and literature study, it is found that the rapid color change ability on this gecko is not related to thermoregulation but more likely associated with camouflage. The type of camouflage strategy employed by Hemidactylus frenatus is background matching

The existence of unconventional mines (TI) which is increasingly prevalent nowadays has penetrated the coast, resulting in the mangrove ecosystem unable to develop properly. One of the areas affected by unconvencional minning activities is on the coast of Takari Beach, Bangka Regency. Takari Beach is one of the areas located on the coast of Rebo Village, Sungailiat District, Bangka Regency. One of the rehabilitation efforts carried out is by planting mangrove seedlings on Takari Beach in 2018 with a total of 500 mangrove seedlings. Mangrove rehabilitation activities are one form of land use conducted in Takari Beach. This activity also needs to be supported by the maintenance and monitoring of planting results to determine the success rate of mangrove planting activities on ex-tin mining land located in the coastal area of Takari Beach, Bangka. The results showed that the percentage of mangroves living at the observation station, namely on plot 1, was 71%. Plot 2's survival rate is 80%. The survival rate for plot 3 is 81%, the survival rate for plot 4 is 54%, and the survival rate for plot 5 is 27%. Plots 1,2 and 3 have a high survival rate, which is around 70-81%. Plots 4, and 5 have a low survival rate, which is around 27-54%. This can indicate that the success rate of mangrove survival can be said to be less successful. This could be due to the fact that there are still floating unconventional mining (TI) activities, which are operating again so that it is suspected that the tailings yield inhibits the growth rate and causes the death of mangrove seedlings.

Biak Numfor and Asmat districts reported as malaria endemic areas in Papua (Papua Global Fund, 2011). Anopheles farauti mosquito is one of the malaria vectors in the region. Malaria control efforts have been made but there are still many cases of malaria. Malaria control will provide maximum results if there is a match between the vector behavior and programs undertaken.
The purpose of this study was to determine the bionomics factors (behavioral) of malaria vector An. farauti mosquitoes in coastal ecosystems (Biak Numfor) and swamp (Asmat); namely: (a). density (b) age and (c) blood-seeking behavior. The method used in this study is human landing collection, resting collection and ELISA blood-feed.
The results showed that the population density of An. farauti mosquito did not have a positive relationship with the number of malaria patients in both study areas. The activity of An. farauti mosquito on blood-seeking at the coastal and swamp ecosystems lasted all night but mainly at 18:00 to 19:00 hour. The study also showed that blood-seeking activity mostly done outside of the house. Age estimation of An. farauti mosquito population at coastal ecosystems ranging from 16-18 days, while in the swamp ecosystem is 12-14 days. Population density, approximately age and blood-seeking behavior indicates that An. farauti mosquitoes on the coastal and swamp ecosystems have the potential to be an effective malaria vector.

Hendrarto, Ign Boedi
Kondisi kerusakan hutan mangrove sudah sangat memprihatinkan. Gangguan hama wideng (Sesarma spp) mempengaruhi keberhasilan penghijauan. Wideng merupakan hama minor yang dapat bergeser sifatnya jika populasinya tinggi pada kondisi tertentu. Oleh karena itu perlu dilakukan penelitian tentang dinamika populasi wideng, sehingga dapat mengetahui waktu kapan wideng berpotensi menjadi hama. Kajian yang sama juga ditujukan terhadap pemangsa potensialnya yaitu Scylla yang ditujukankan untuk mengetahui tekanan predator terhadap wideng dan peluang pemberdayaannya sebagai pakan budidaya. Penelitian bersifat observasional yang dilakukan di kawasan mangrove Tapak, Tugurejo. Sampling dilakukan di enam stasiun yang dipilih secara justified random sampling. Kajian eksperimental menggunakan Rancangan Acak Lengkap(RAL) dengan tiga perlakuan dan tiga ulangan yang dilanjut dengan uji Beda Terkecil. Hasil memperlihatkan bahwa populasi wideng mengikuti pola unimodal dengan puncak populasi pada bulan Nopember mencapai 30/m2.Kepiting Scylla memasuki musim tangkap sejak Oktober hingga Maret dan mencapai puncaknya pada bulan Pebruari. Kepadatan populasi tersebut selaras dengan keberadaan wideng yang juga tinggi populasinya, sehingga dapat dipergunakan sebagai pakan budidaya sekaligus menekan sifat hamanya.Kepiting bakau menyukai wideng pada semua ukuran, dimana tidak membedakan ukuran badan wideng mangsanya pada hari ke-5, meskipun pada hari ke-3 memperlihatkan kecenderungan menyukai ukuran badan yang kecil; sehingga wideng bersifat fleksibel sebagai pakan budidaya Scylla.

Profil Kolestrol Darah Tikus Setelah Pemberian Virgin Coconut Oil Dan Minyak Zaitun
Djaelani, Muhammad Anwar
Tingginya kadar kolestrol dalam tubuh menjadi pemicu munculnya berbagai penyakit. Masyarakat berusaha menurunkan kadar kolesterol dalam tubuhnya. Komponen VCO berupa asam lemak jenuh sekitar 90% dan asam lemak tak jenuh sekitar 10%. Asam lemak jenuh VCO didominasi oleh asam laurat. VCO mengandung asam laurat dan asam kaprilat. Keduanya merupakan asam lemak rantai sedang yang biasa disebut Medium Chain Fatty Acid (MCFA). Minyak zaitun atau Olive oil mengandung lemak tak jenuh yang tinggi terutama asam oleat dan polifenol. Polifenol merupakan antioksidan yang dapat mengikat LDL teroksidasi. Penelitian ini bertujuan untuk mengkaji efek asam lemak jenuh yang menggunakan VCO dan efek asam lemak tak jenuh yang menggunakan minyak zaitun terhadap profil kolesterol darah pada tikus putih. Penelitian ini menggunakan Tikus putih jantan sebanyak 25 ekor yang dibagi dalam 5 kelompok perlakuan yaitu P1 adalah kelompok kontrol, P2 kelompok yang diberi VCO 5 mL/kg pakan, P3 kelompok yang diberi VCO 10 mL/kg pakan, P4 kelompok yang diberi minyak zaitun 5 mL/kg pakan dan P5 kelompok yang diberi minyak zaitun 10 mL/kg pakan. Tiap perlakuan diulang sebanyak 5 kali. Perlakuan selama 4 minggu. Variabel yang diamati meliputi kadar Kolesterol total, HDL dan LDL darah tikus. Data yang didapat, dianalisis menggunakan ANOVA. Hasil yang didapat menunjukkan pada perlakuan dengan VCO menunjukkan pengaruh yang tidak signifikan terhadap perubahan ketiga variabel penelitian. Pada perlakuan dengan minyak zaitun kadar HDL tidak terdapat perbedaan yang signifikan antar kelompok perlakuan, kadar Kolesterol total pada kelompok perlakuan menunjukkan penurununan yang tidak signifikan dan kadar LDL pada kelompok perlakuan 10 mL/kg pakan menunjukkan penurununan yang signifikan. Dapat disimpulkan bahwa pemberian VCO tidak berpengaruh pada profil kolestrol darah tikus normolipidemia, dan minyak zaitun berpotensi menimbulkan respon penurunan profil kolesterol tikus pada kadar ≥10 mL/kg pakan.
Kata kunci: tikus putih, Kolesterol total, HDL dan LDL, Minyak Zaitun, VCO.

So far, the effect of habitat alteration on Bryofauna community have not been known yet. The objective of this study is to determine community structure attributes i.e., abundance, diversity and composition of bryofauna living in coffee and tea vegetation. The study was located in Ungaran Mountain, District of Semarang Indonesia. Bryofauna were extracted from moss using Tullgren funnel method and were identified until possible taxa. Bryofauna sampling was conducted both in coffee and tea vegetation. Bryofauna were extracted from the moss using Tullgren funnel method. The result shows that Acari was the most abundant both in coffee and tea area. Generally, bryofauna was more abundant in the coffee vegetation than in the tea vegetation. The diversity of bryofauna was not affected neither by altitude nor vegetation. However, the diversity of bryofauna seems affected more by their host, bryophyte.
Keywords: Bryofauna, Acari, coffee and tea vegetation.

Insects in agricultural ecosystem can play a role as pests or natural enemies. The abundance and diversity of insect pests and natural enemies are interconnected because insect pests are food for natural enemy insects. The aims of the study were to compare the abundance and diversity of pest insects and natural enemies of corn and rice plant, and to determine the similarity of pest insects and natural enemies of corn and rice plant using crop rotation systems. The sampling has performed four times i.e, in the vegetative phase of corn, generative corn, vegetative rice, and generative rice. The sampling method used sweep net method. The results showed that the number of individual pest insects and natural enemies of each growth phase of corn plants were lower than rice plants. The number of species pest insect and natural enemies of each growth phase of corn plants were lower than rice plants. In addition the diversity of pest insect of each growth phase of corn plants was higher than rice plants while the diversity of natural enemies in each growth phase of corn plants was lower than rice plants. The diversity index of pest insects and natural enemies of each growth phase in corn plants and rice plants was in the medium category. The presence of pest insects and natural enemies in each growth phase of corn and rice plants shows the species in the two compared ecosystems were different.

Milkfish is one of the main commodities in the field of fishery and is known to be the most cultivated. One of the important’s factors to the success of milkfish cultivation is feed availability, both quality and quantity. Feed quality is an important aspect that must be fulfilled because of its relation to nutrients required for the fish growth. Azolla pinnata has a good potential that can be used as an additional ingredient for the fish growth because of its protein-rich content. This study is aimed to examine the effect of Azolla pinnata powder feed on growth of milkfish (length and body weight). This research was conducted in May – July 2017 at Aquatic Animal Health Management Laboratory, Center of Brackish Water Aquaculture of Jepara. The research design used is a Complete Randomized Design (CRD), using five treatments with different concentrations of Azolla pinnata powder, i.e. 0% as control, 10%, 20%, 30%, and 40%. Each treatments consist of three repeatitions. The parameters observed were milkfish growth (length and body weight) and dissolved oxygen (DO). Data were analyzed by Analysis of Variance (ANOVA) method. If the data showing significant differences it will be continued with Least Significance Different (LSD) test. The results showed that the administration of Azolla pinnata powder on the feed significantly influenced the growth (lenght and body weight) of milkfish. The most optimal and efficient feed composition for milkfish growth is done by feeding 40% of Azolla pinnata powder. The overall dissolved oxygen (DO) is still in suitable condition for the cultivation of milkfish.

Indonesia is the fourth largest chili producer in the world. In 2017, chili (Capsicum frutescens) was ranked fifth as the largest seasonal vegetable commodity products. The productivity of chili cultivation in Indonesia is hampered by pests and diseases. One of the most common pests that attack chili plants is the armyworm Spodoptera litura (Lepidoptera: Noctuidae). Lysinibacillus sphaericus bacteria have the potential as Plant Growth Promoting Rhizobacteria (PGPR) as well as a bio control agent. This study aims to obtain L. sphaericus isolates that can increase the growth of chili and to determine the effect of L. sphaericus isolates which have the potential for PGPR on the growth of the armyworm feeding on the chili plants. The research method used is experimental research conducted at the Laboratory of Entomology and Sawitsari Research Station, Universitas Gadjah Mada. This study used three replicate by inoculating one millilitre per plant. The results obtained from testing the 105 isolates in the collection of the Faculty of Biology, Universitas Gadjah Mada showed that the isolates that can increase the growth of chili plant indicated with its plant height, were isolates A42, A49, A19, A5, and A38. While the results of plant with the highest number of leaves showed the isolates A49, A42, A19, A38, and A28 were the best among the isolates tested. Some L. sphaericus isolates could increase plant growth compared to the control, but not statistically significant. These bacteria by inoculating one mililitre to plant could not be used as a bio control agent in S. litura because they did not have a significant different in leaf damage to the control.

Luka kronis penderita Diabetes Mellitus (DM) tipe 2 yang semakin parah berpotensi diamputasi. Terapi antibiotik berbahan kimia sintetik yang diberikan memiliki kelemahan, yaitu menimbulkan resistensi bakteri, alergi, gangguan pernafasan, juga harga relatif mahal. Alternatif pengobatan adalah menggunakan bahan alam yang mengandung senyawa bioaktif dengan aktivitas farmakologi untuk proses penyembuhan luka. Namun, senyawa bioaktif ini mudah rusak oleh berbagai faktor. Teknik enkapsulasi nanokitosan dapat meningkatkan efisiensi dalam penyembuhan luka. Riset ini memanfaatkan daun binahong terenkapsulasi nanokitosan sebagai bahan sediaan salep untuk luka diabetes. Riset diawali dengan ekstraksi senyawa bioaktif daun binahong, sintesis ekstrak binahong terenkapsulasi nanokitosan (EBTN), serta pembuatan salep. Adapun uji yang dilakukan, yaitu fitokimia, PSA, Zeta, dan In vivo terhadap tikus. Riset menggunakan Rancangan Acak Kelompok (RAK) dengan 5 perlakuan, Kontrol Negatif (K-), Kontrol Positif (K+), P1 (EBTN 20%), P2 (EBTN 30%), dan (EBTN 40%), tiap perlakuan diulang 4 kali. Uji data dianalisis menggunakan ANOVA dan uji lanjut Tukey (P<0,05). Selain itu dilakukan uji karakterisasi fitokimia, PSA, dan Zeta Potensial. Uji fitokimia menunjukkan bahwa ekstrak daun binahong positif mengandung flavonoid, alkaloid dan saponin. Uji PSA dan Zeta menunjukkan bahwa EBTN memiliki ukuran nanopartikel (169 nm) dan kestabilan yang baik dengan nilai apparent (-40,2 ± 4,65 mV). Hasil uji In vivo terhadap persentase penyembuhan luka pada perlakuan K+, K-, P1, P2, dan P3 berturut-turut adalah 41,6%; 31,6%; 46,6%; 55%; dan 40%. Berdasarkan hasil riset yang dilakukan, dapat disimpulkan bahwa esktrak daun binahong dapat dienkapsulasi dengan nanokitosan sebagai bahan sediaan salep untuk luka diabetes dengan dosis paling efektif sebesar 30%.

In contrast to other toxic trace metals, Cr has received little attention. Since valence level of chromium determines its toxicity, chromium is categorized as unique heavy metal. Chromium hexavalent (Cr6+) has the biggest toxicity among other valence levels. Seed germination and seedling growth are sensitive to heavy metal stresses. This research aimed to find out the responses of seed germination and seedling growth of 12 sorghum varieties toward Cr6+. Seed germination and seedling growth experiment was done on 12 sorghum varieties (Badik, UPCA-1, Keris, Keris M3, hegari Genjah, Gambela, Selayer, Sangkur, Mandau, Batari, Kawali, dan Numbu), planted in petridishes with Cr6+ treatment in form of chromate (K2CrO4) and dichromate (K2Cr2O7) compounds with 0, 50 and 500 mg of Cr/l concentration for a week. The parameters measured were the number of seeds germinate each day; the length of radicle and plumule, and fresh and dry weight at the end of experiment. The results showed that higher concentration of Cr6+ both in form of dichromate and chromate, significantly decreased the length of radicle and plumule, fresh and dry weight, and SVI (seedling vigor index) value. However, index germination (GI) value and percentage of germination of the 12 varieties sorgum significantly increased in the treatment of 50 mg Cr/l Cr6+ in form of dichromate and chromate. The treatment of dichromate compound showed bigger effect than chromate toward variables of seed germination and seedling growth of sorghum. It was noticed that 12 sorghum varieties possessed an integrated complex of adaptation to cope with the range of form of compound and concentration of Cr6+. Based on the responses of seed germination and seedling growth, Kawali, Hegari, Keris, Keris M3, Mandau, and Selayer varieties was more susceptible toward Cr6+ toxicity, and Sangkur, Selayer, Batari, and Numbu was more tolerant than other varieties.

Green Mustard (Brassica juncea L) ; Rice washing water ; Photosynthetic pigment content ; Vegetative growth.
Mustard plants are a type of vegetable favored by most people. Demand formustard plants continues to increase along with the increasing population and awareness of nutritional needs, but there are obstacles in increasing the production. This is due to the lack of nutrients needed by the mustard plant for its growth. One effort to increase the production of mustard plants is by adding nutrients through fertilization. Fertilizers are divided into two types, namely organic and inorganic fertilizers. However, long-term use of inorganic fertilizers can reduce soil quality and environmental health. One alternative to overcome these problems is to use liquid organic fertilizer in the form of fermented rice washing water. This study aims to determine the effect of 1-day fermented rice washing water and 15-days fermented rice washing water at different concentrations on photosynthetic pigment content and vegetative growth of green mustard plants and find out the best dose of rice washing water for the growth of green mustard plants. The study used a Completely Randomized Design (CRD) of 1 factor with 5 treatments. Each treatment with 4 replications with ordinary water as a control, 1-day fermented rice washing water with the concentration of 50% and 100%, and 15-days of fermented rice washing water with the concentration of 50%, and 100%. The results showed that the watering on 1-day fermented rice washing water with the concentration of 50% and 100% and 15-days of fermented rice washing water with a concentration of 50% had no effect on all parameters but the watering of 15-days fermented rice washing water with a concentration of 100% had an effect on increasing the plant height, number of leaves, leaf area, plant fresh weight, and plant dry weight. The growth of mustard green plants (Brassica juncea L) is best obtained in the treatment of 15-days fermented rice washing water with a concentration of 100%.

The choice of using pesticides with natural ingredients or synthetic chemicals is a differentiator between organic farming systems and inorganic farming systems. Pesticides are additives in agriculture to control pests or weeds. Abamectin is one of the active ingredients that can be found in pesticides. Ground microarthropods are members of the soil mesofauna, which are soil animals that have a body size ranging from 0.2-2 mm. The purpose of this study was to determine the effect of differences in the application of pesticides on a field or laboratory scale on the structure of soil microarthropod communities. Soil samples were taken from three agricultural lands, namely Bandungan inorganic agricultural land, Kopeng inorganic agricultural land and Kopeng organic agricultural land. The study was conducted in August to December 2018 in the Ecology and Biosystematic Laboratory of the Department of Biology, FSM Undip. Found a total of 60 species species richness originating from 13 orders. The application of pesticides which include the concentration and frequency of pesticide spraying has a negative influence on the structure of soil microarthopod communities. Application of abamectin pesticides on a laboratory scale proves that the administration of abamectin pesticides that exceeds the recommended concentration will adversely affect the structure of the soil microathropod community. Based on statistical tests of soil microarthropod species diversity from the results of the application of pesticides on a field and laboratory scale is significantly different.

Late blight disease caused by Phytophthora infestans, is probably the single most important disease of potatoes worldwide. Infected plants were quickly killed and were difficult for replanting, causing significant losses for the growers. Various control methods were examined including the use of biocontrol agents of Trichoderma agent. The research objective was to determine the ability of biofungicide product from Temanggung local farmer group to delay late blight disease incidence on potato plants in the field. The in vivo experiment was carried out at potato land area located at Kaponan Sub District, Pakis District and Magelang Regency. Complete Randomized Design with six treatments and twenty replication was applied and each of which was placed in a different plot. On the first plot treatment was given chemical fertilizer application (P0);The second plot treatment (P2) was given with leaking and spraying application of biofungicide ( H-7, H+8, and H+15); The third plot treatment (P3) was given with spraying application of biofungicide (H+8, H+15, and H+21); The fourth plot treatment (P4) was given with spraying application of biofungicide (H+8, H+15, H+21 and H+28), and the last tretment (P5) was given with no application of chemical fungiside and pesticide. Result of the research showed that application of biofungicide could delay late blight disease incubation period until 14 days compared the control treatment (P0). The percentage of viability of the active biofungicide after being stored for 4 months still shows a high value of 87.13%, so that this local product biofungicide still meets the feasibility standard for its application in the field.

Kombucha tea beverage obtained by fermenting sweetened green tea for 12 days with Acetobacter xylinum and Saccharomyces which produce various kinds of organic acids, vitamins, and acts as a probiotic. Kombucha tea role as growth promoter is to enhance the metabolic processes in the digestive system of broiler, so that the nutrients can be absorbed and fulfilled properly for optimal growth and development. The research was conducted from September to October 2014 in the Laboratory of Biological Structure and Function, Diponegoro University. Posterior limb (femur-tibiotarsus) meat-bone ratio analysis was used to investigate the effects of kombucha tea on the productivity of broiler chicken. A total of 20 broiler chickens were randomly divided into 4 treatment concentrations ( 0%, 10%, 20%, and 40% of kombucha tea in drinking water) for 32 days. Statistical analysis using ANOVA at 0,05 significance level and Duncan’s Multiple Range Test showed significantly different results on body weight and water intake, while feed intake, meat weight, bone weight and meat-bone ratio showed no significant results. It can be concluded from this study that the decrease of broiler chicken body weight due to consumption of 40% kombucha tea concentration in drinking water, do not cause a decrease in posterior limb meat and bone weight so that the posterior limb meat-bone ratio were not significantly different.
Key words: Kombucha tea, broiler chicken, posterior limb, meat-bone ratio.

Perbandingan Karakter Ekologi OPT (Organisme Pengganggu Tanaman) Dan Musuh Alaminya Pada Masa Tanam Yang Berbeda Di Sawah Organik Dan Anorganik
Hadi, Mochamad
Departemen Biologi, Fakultas Sains dan Matematika, Universitas Diponegoro
OPT, musuh alami, masa tanam, sawah organik dan sawah anorganik.
Kualitas dan kuantitas tanaman padi sebagai produsen dalam jaring makanan akan mengundang hadirnya serangga herbivore sebagai konsumen pertama. Hadirnya serangga herbivore atau sering disebut OPT (Organisme Pengganggu Tanaman) di ekosistem sawah akan mengganggu produktivitas tanaman padi. Namun demikian hadirnya OPT di ekosistem sawah juga akan mengundang serangga musuh alaminya sebagai konsumen tingkat kedua, baik predator maupun parasitoiid, yang akan mengontrol keberadaan OPT. Pertanian organik adalah manajemen pertanian yang meniadakan penggunaan bahan kimia sintetik sebagai sarana produksi, baik berupa pupuk maupun pestisida. Penelitian bertujuan untuk mengetahui bagaimana karakter ekologi serangga OPT dan musuh alaminya pada masa tanam yang berbeda yaitu padi dan palawija pada sawah organik dan anorganik. Karakter ekologi dianalisis dengan jumlah jenis, jumlah individu, indeks keragaman (H’), kelimpahan (Di) dan kemerataan (e). Hasil penelitian menunjukkan bahwa secara umum karakter ekologi OPT dan musuh alami di dua masa tanam yang berbeda hampir sama, baik di sawah organik maupun anorganik. Jumlah jenis maupun jumlah individu OPT dan musuh alaminya di sawah organik maupun anorganik pada dua masa tanam yang berbeda juga menunjukkan hasil yang hampir sama. Keragaman dan kemerataan persebaran OPT dan musuh alaminya juga tidak berbeda pada kedua masa tanam yang berbeda. Namun demikian pada kedua masa tanam menunjukkan perbedaan dalam jenis OPT maupun musuh alaminya yang hadir, namun antara sawah organik dengan sawah anorganik tidak menunjukkan perbedaan.
Kata kunci : OPT, musuh alami, masa tanam, sawah organik dan sawah anorganik.

The Indonesia needs of Bioethanol were 390.000 kL in 2012, but the local ethanol production only able to cover less than 4% from the needed. The high demand of the bioethanol encourage for another innovation in ethanol production more efficient and effectively. Seaweeds and the residual pulp of Gracilaria sp. could be useful as substrate for bioethanol production, because of the high amount of polysaccharide, cellulose and galactan type. Unfortunately, this cellulose and galactan had through the saccharification process first, before they can be used as substrates in bioethanol production. This study examined the difference between two saccharification process which are acid hydrolisis using H2SO4 1% and enzymatic process using Aspergillus niger on the use seaweed and the residual pulp of Gracilaria sp. for bioethanol production. Bioethanol production been conducted for 5 days and in each 24 hour, the sampling for cell number variable, reduction sugar amount variable, and medium fermentation pH variable had been retrieved. The ethanol amount calculation in the last incubation phase conducted using distillate fermentation spesific gravity methode. The highest ethanol was obtained 5,50% by treatment using seaweed medium with acid hydrolisis. The anova analysis result showed that interaction between medium variable and hydrolisis didn’t have signifficant influence toward ethanol product. It showed that seaweed and the residual pulp of Gracilaria sp. had same quality and they can be useful as main component of bioethanol production which are hydrolisis by enzymatic or acid hydrolisis.

Infectious Hypodermal and Hematopoietic Necrosis Infectious Virus (IHHNV) is the most important DNA virus which can lead to Runt Deformity Syndrome (RDS) in vaname shrimp. The RAPD technique can be used to determine the resistance of a species to a disease. This research aimed to screen and identify RAPD markers which could distinguish the resistance of vaname shrimp to IHHNV reared at intensive and semi-intensive pond. The DNA template was amplified by PCR using 5 primers : OPA 06, OPA 08, OPA 19, OPD-02 and OPZ-15. The results showed that only the primer OPA-19 and OPZ-15 were able to produce 100% polymorphic bands with sizes from 400-1700 bp as well as showing the resistance IHHNV in vaname shrimp. Based on these results, vaname shrimp which reared at the intensive pond were more resistant to IHHNV compared with the semi-intensive pond.

Quail, antigen, body weight gain, relative organ weight, erythrocyte profile
Coturnix coturnix japonica is one of quail the promising commodities to breding. Health management of poultry in livestock such as quail has problems related to the threat of disease from the environment. Diseases caused by disease agents attack birds resulting in morbidity and mortality so that farmers experience losses. This study aims to determine the effect of injection of two different antigens at different time frames on body weight gain, relative organ weight and erythrocyte profile in 5-month-old male quail. The study used an experimental method of completely randomized design (RAL) with animals as many as 28 male quails divided into 7 groups with 4 replications, namely K0: not injected with antigen, P1: injection SDMD 2%, P2: SDMD injection 2% and ND vaccine, P3 : injection ND and SDMD 2% in week 4, P4: injection vaccine ND, P5: injection SDMD 2% and SDMD 2%, P6: injection treatment ND vaccine and injection ND vaccine. Data obtained by body weight gain, relative organ weight, erythrocyte count, hemoglobin level and hematocrit value. Data were analyzed by Analysis of Variance (ANOVA) using MiniTab17. The results showed that organ weight gain, relative organ weight, heart, heart, pancreas, kidney, lung, spleen, erotrocyte count, hemoglobin level, and hematocrit value were not significantly different (P> 0.05) with control treatment so it can concluded that the effect of antigen injection does not affect the weight gain of organs, the relative weights of the liver, heart, pancreas, kidney, lungs, spleen, the number of erotrosites, hemoglobin levels, and hematocrit values.

Taxonomic Status, Morphological character, Diagnostic character, Phylogeny
Huia masonii (Boulenger, 1884) or Javan Torrent Frog is one of the frogs that are endemic on the island of Java. The presumption of two different forms of Huia's morphology according to Manthey and Dezer’s publication makes a systematic study of these species among their populations necessary. In this study, a systematic study of H.masonii was conducted between populations with a morphological approach to determine differences in character between populations, taxonomic status and phylogeny between populations. A total of 111 adult specimens (62 males and 49 females) from each population with good condition were observed morphologically. Data analysis was performed using Principal Component Analysis (PCA) and UPGMA Clustering. The results of this study indicate that there are no fundamental differences in the characteristics of each population so that there are no characters that can be used as diagnostic characters. The absence of this diagnostic character also makes the taxonomic status of H. masonii morphologically unchanged. Besides relationship between populations is still close to one another morphologically

Sugar national supply more and more decreases and can not meet the market needs. The research has been done to find alternative natural sweeteners including inulin from dahlia tubers (D. variabilis Willd). Dahlia tuber can produce 95% of yield of fructose syrup in an enzimatic reaction by inulinase (E.C.3.2.1.7). Inulinase is inductive enzyme that can be produce by P. manshurica. The production of fructose needs to be optimized to get optimum product. The optimization can be done by modifying the nutrient content in the medium such as K2HPO4 and variation of incubation time. The purpose of this study is to determine the concentration of K2HPO4 and optimum incubation time for P. manshurica. This research was conducted in Microbiology Laboratory, Biology Department, Faculty of Science and Mathematics Undip. The examined variable is the growth of yeast cell, inulinase activity, invertase, and the I/S ratio. This research was conducted experimentally using Randomized Complete Block Design (RCBD) factorial pattern with 2 factors, the first factor was the concentration of K2HPO4 (P), with concentration level (g/L) of 0.5 (P1), 1.0 (P2), and 1.5 (P3). The second factor was incubation time (W) with 12 hours (W12), 18 hours (W18), and 24 hours (W24). Every treatment was repeated three times. The collected data were analyzed using ANOVA. If there was a treatment effect, it will be continued with Duncan test on 5% significance level. The result of analysis show that the highest cell growth and the maximum production of inulinase enzyme was in P3W24 occurs in P3W24 (K2HPO4 1.5 g/L and 24 hours incubation time) treatment at 0.428 IU, but efficient in P1W12 treatment as much as 0.365 IU.

Spring conservation require serious concern on the economic advantages for the society. Without economic advantages achieved from the conservation activities, the conservation programme should face intense conflict of land utilization. Plantation of economically valuable conservative plant species is one of the proposed solution to overcome the problem. This research aimed to identify the economic value of conservative plant species found in “Sendang Kalimah Toyyibah” surrounding. Research was conducted through field observation involving 4 line transects and 4 square transects at each line with transect size of 20 m x 20 m. Plant identification was conducted for tree strata. Data analysis was including diversity, evenness and importance index of respective plants. Economic valuation was conducted through literature study. The result showed there were 28 plants species availabile in “Sendang Kalimah Toyyibah” surrounding. Among the plant species 22 of the had been identified to provide conservative function, while 6 of them weren’t including Banana, Papaya, Melinjo, Pangi, Longan and Stink Bean. Instead of providing conservative function, most plants also provide economic advantages including wood, fruit, flower, bud, leaf, fibre, sugar, peel and bean products while only 3 of them were not identified including Banyan, Manila Tamarind and Amboyna Wood. Plantation of economically valuable conservative plant species is recommended to support the conservation of the spring as well as to provide economic advantage for the society.

Thirty sediment samples had been taken from the Tapak Formation of Kedung Randu areas, Banyumas, to reconstruct the diversity of mangrove flora from this area the past. This samples were processed for palynological slides used standard palynology preparation method. The microscopic identification of palynomorphs were done to identify taxa of paleoflora. Fifty-six types of pollen and spores fossils had been identified and 22 types were mangrove pollen-spores fossils. This fossils could be grouped into major mangrove (Zonocostites ramonae/Rhizophora type, Spinizonocolpites echinatus/Nypa fruticans, Florschuetzia levipoli/Soneratia caseolaris and Avicennia type); group of minor mangrove (Retitricolporites sp./Excoecaria sp., Discoidites novaguenensis/Brownlowia type, Camptostemon and Acrostichum aureum), and a group of plant associations (Retitricolporites equatoralis/Calophyllum type, Dicolpopollis sp./Calamus type, Racemonocolpites sp./Oncosperma, Marginipollis concinus/Barringtonia, Pandaniidites sp. /Pandanus, Terminalia catappa, Ilexpollenites sp./Ilex, Stellatopollis sp./Croton type, Acanthaceae type, Cyperaceaepollis/Cyperaceae, Podocarpidites/Podocarpus, Aglaia type, Haloragacidites/ Casuarina and Verrucatosporites usmensis/Stenochlaena palustris. Stenochlaeniidites papuanus and Podocarpus imbricatus were found in the samples. Tapak Formation was included in the last section of the Podocarpus imbricatus/Dacrycarpidites australiensis Zone of Java Palynological Zonation, and this formation was in the age of Late Pliocene towards Pleistocene.
Key word: Tapak Formation; major-minor-plant associations of mangrove; palynological zonation

Antioxidant, Celosia argentea Linn., Correlation, Environment, Secondary Metabolite
Celosia argentea Linn. is a herbaceous plant of Amaranthaceae family. The plant has antioxidant property. The antioxidant capacity is determined by the existence of secondary metabolite of which phenolics compound is one of them. This research aim was to determine the correlation between phenolics compound content and the growing environment with the antioxidant activity of Celosia argentea Linn. The plants were obtained from three different locations in Salatiga area included Ngronggo Village Landfill (TPA), Jalan Raya Lingkar Selatan (JLS), and in Blotongan Housing Complex areas (PB). The fresh leaves of the plant were extracted by maceration method using ethanol 96% in the room temperature for 48 hours. The determination the phenolics content was using Folin-Ciocalteu method, while antioxidant activity using DPPH assay. The phenolis content of C. argentea Linn. leaves were 10,22; 6,99; 4,97 ppm from TPA, JLS, and PB respectively, while the IC50 values of antioxidant activity were 2,98; 3,18; and 3,35 ppm respectively. There were a correlation between antioxidant activity and phenolics compound with the growing environment of C. argentea Linn. The higher of phenolics compound content, the lower the IC50 value (higher an antioxidant activity). The phenolics content was also has a strong correlation with environment.

Dragonflies have an important role for the stability of the ecosystem that is as predator and prey at the same time. The availability of food resources and optimal environmental conditions affect the species richness of dragonflies in the habitats. Reasearch on dragonfly comunity structure aims to find out the differences of community structure in each habitat type in the region of Curug Lawe Benowo. The research was conductet in 4 different stations which focus on species of dragonfly, amount of an individual species, habitats, environmental conditions, and the corellation between the variables. The method used is point count. The results showed that there are 19 dragonfly species which came from 7 different Family. The total number of individuals encountered from 4 stations is 205. The common species that can be found in all of the stations is Euphaea variegata. The level of diversity are medium, the level of evenness is fairly even. Similarity of species in any habitat types indicate that the habitats has a three kind of similarity levels that is fairly equal, less equal and not equal. Data analysis shows that there is a corellations between environmental conditions, and dragonfly species, affecting abundance and distributions of a dragonfly in the habitats, and can be used to describe dragonflies community structure in the region.
Key words: Community structure, dragonfly, Curug Lawe-Benowo

Oil palm, peatland, PGPR activities, biofertlizer
Peatlands have characteristics of low pH and lack nutrients. Oil palm is the main plant commodity in peatland management. Oil palm roots have been known to be a nutrition source for the growth of soil microbes, especially bacteria around their roots or PGPR. PGPR are a group of bacteria that play an important role in supporting plant growth and health. The purpose of this research was to obtain PGPR potential from oil palm roots which can be used as candidates for biofertilizer agents. In this study, the isolation and selection of PGPR isolate from oil palm roots on oil palm plantations in Central Kalimantan were carried out based on their plant growth-promoting traits, including the activity of producing Indole Acetic Acid (IAA), phosphate solubilizing, N-fixing, K solubilizing, siderophore production, ACC deaminase activity, proteolytic activity, cellulolytic activity, and ligninolytic activity. A total of 17 isolates were selected to be tested for their multiple activities ability. The final results of the PGPR characterization showed that of the seventeen isolates, all isolates had PGPR activity at least three different abilities. From the seventeen isolates, it was found that the SW 5.5 PK 3A isolate had the highest IAA production activity (58,50 ppm), SW 4.10 PK 1A isolate had the highest K solubilizing index (3,16), SW 8.5 PK 1A isolate had both the highest P solubilizing index (3,73) and the highest siderophore zone index (5,20), SW 4.11 PK isolate had the highest proteolytic index (4,80), and SW 4.10 PK 1A.P isolates had the highest cellulolytic index (5,11).
