The process of bioconversion of palm kernel cake (PCK) for the production of Black Soldier Fry larva biomass as a fish feed can be improved by fermentation process. The purpose of this research was to determine the amount of biomass production and nutritional content of maggot as a result of bioconversion fermented palm kernel cake (PCK) by using probiotic. PCK used in this research were obtained from one of palm processing industry (PTP VII Lampung). Fermentation process was using microbes (probiotics) amount of 0% (F0), 3% (F3), 4% (F4), and 5% (F5) in 1 liter of water, then it's mixed with PKC to help fermentation process. Each treatment was using 3 replication. The fermentation process was done in a 3 liters volume of bucket covered by perforated black plastic/trash bag to avoid the heat by light and the rainwater. The buckets were prepared, placed and stored in a cool and humid place by using a bamboo/wooden racks. If the media was prepared, Black Soldier Fly (BSF) insect would automatically come and lay its eggs on it.. Observations were made within 2 weeks after the media were prepared and then harvested 3 times during one week. The biomass of harvested maggot were clasified into 3 group of size, they are <1cm, 1-1.5cm, and >1.5cm, then the weight were measured. The result showed that the fermented media did not give any affect for the biomass of maggot, but had an effect on the maggot nutrition. The biomass of maggot in the treatment F0 (control) was not significantly different from treatment F3 (3%) (p>0.05), while the higher dose of probiotic (F4 and F5) were lower than control. The proximate composition of maggot showed that crude protein and fat parameter were significantly different for every stage of fermentation treatment. Treatment F3 has the highest crude protein and significantly different from F0 and F5 (p<0.05), while the fat contents decreasing significantly at higher fermentation dose. Likewise, the total amino acid, in fermentation F3 was significantly higher compared to control and other treatments. Thus, the dose of fermentation (probiotic in water) 3% for the PKC was optimal to produce biomass and nutritional content of maggot.

The aim of this study was to know the effect of temperature shock gift time distance from fertilization on the triploidy individual process, persentage of hatching rate and survival rate of larva patin catfish. Temperature shock gift time distance treatment from fertilization process is given each 120 second, 180 second, 240 second and 300 second in temperature 40C during 90 second. Each treatment is done as much as 3 times. Hatch and larva maintenance is done in aquarium and hapa for fingerling activity. The result shows that temperature shock gift time distance treatment from fertilization process gives real result on the triploidy individual procces in patin catfish (p<0,05). Highest percentage triploidy individual is got in temperature shock gift time distance from fertilization process 180 second as big as 83,33 %. The growth level patin catfish day 28 show enhanced in line with individual percentage enhanced triploidy from each treatment. The highest growth rate is got from temperature shock gift time distance treatment from fertilization process as big as 11,13 %. Keywords: catfish, triploidy, time distance, temperature shock

Pacific white shrimp is one of the primadona of fishery commodities. The development of Pacific white shrimp can be done by using floating net cage (FNC). Shrimp culture in sea floating net cage is the one of alternative aquaculture of environmentally friendly shrimp cultivation and potentially become applicative technology of shrimp farming in the future. The aims of this study were to know the feasibility of white shrimp culture in sea floating net cage. The study was conducted by using descriptive and analytic method with 18 pieces of cage. Analysis of the feasibility using net present Value (NPV),Internal Rate of return (IRR), Net Benefit-Cost Ratio, Gross Benefit-Cost Ratio, Payback Period (PBP), and Break Even Point (BEP). The study result show that the NPV is IDR 43,315,360.00; IRR is 21.47%; net B/C ratio is 5.11, gross B/C ratio is 3.71; PBP is 6 months and 9 days and BEP is 1,837.82 kg of shrimp biomass or IDR 147,025,891.18 of the value of sales. The final result of feasibility analysis of shrimp culture in sea floating net cage is feasible to run.

Salah satu terobosan untuk meningkatkan produksi udang adalah memanfaatkan laut dengan keramba jaring apung. Tujuan dari penelitian ini adalah untuk membandingkan komposisi kimia dari udang putih (Litopenaeus vannamei) dan daging udang windu (Penaeus monodon) yang dibudidayakan di keramba jaring apung. Hasil dalam penelitian ini menunjukkan bahwa daging udang putih memiliki kandungan protein dan abu yang lebih tinggi daripada daging udang windu. Komposisi langsung pada otot udang diatur oleh banyak faktor, termasuk spesies, tahap pertumbuhan, pakan dan musim.

The success of masculinization in tilapia shows that the use of the hormone 17?-methyltestosterone (MT) is more effective than temperature. However, the use of hormones by feeding through food has not shown better results compared to soaking the larvae. Even though the application through feeding is easier to do. Therefore, in this study, the administration of hormones through feed will be carried out with the experimental time of feeding exceeding the highest critical time, which is for 30 and 50 days. D'Cotta et al. (2007) and Ijiri et al. (2008) states that the critical time for sex change in tilapia is 9-15 days after fertilization/day post-fertilization/dpf. The objective to be achieved in this study is to obtain the optimal duration of 17? Metiltestosterone hormones through a feed to produce male tilapia mono sex. Treatment using 17?-methyltestosterone at a dose of 60 mg/kg with a treatment duration of feeding 0, 30, and 50 days. The influence of the length of time for feeding containing hormones was tested using the ANOVA test at 95% confidence intervals. The results obtained showed that the use of 17?-methyltestosterone in reversal sex with a dose of 60 mg/kg of feed with a duration of 0, 30, and 50 days showed a difference in the number of male tilapia produced. However, there was no noticeable difference in the male sex ratio at 30 and 50 days of feeding. So it can be concluded that feeding 17?-methyltestosterone hormone through the feed for 30-50 days after hatching can increase the male sex ratio in tilapia by more than 80%.

Budidaya udang vaname (Litopenaeus vannamei) memiliki prospek sangat bagus untuk dikembangkan. Ketersedian juvenil (benih) udang vaname yang berkualitas sangat diperlukan untuk kegiatan pembesaran. Pendederan udang vanname memiliki beberapa kendala karena dalam proses pelaksanaannya menggunkaan padat tebar tinggi dan jumlah pakan yang dibutuhkan semakin tinggi. Kondisi penggunaan pakan yang tinggi tersebut dapat berdampak terhadap kualitas air budidaya. Hasil limbah dari metabolisme dan sisa pakan yang tidak termakan dapat menjadi toksik bagi udang. Teknologi yang dapat mengurangi resiko terhadap limbah yang bersifat toksik pada udang salah satunya adalah teknologi bioflok. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan Survival Rate (SR) pendederan udang vaname menggunakan teknologi Bioflok. Metode penelitian yang digunakan yaitu membandingkan secara langsung dengan analisis secara desnkriptif. Penelitian dilakukan dengan menggunakan wadah bak permanen yang dilapisi terpal dengan ukuran 3m x 5m x 1,2m sebanyak 2 buah. Tiap bak diisi air laut dengan salinitas 30 ppt sebanyak 12.000 liter dilengkapi dengan 24 titik aerasi dan sebuah mikro bubble. Benih udang vaname yang digunakan berukuran PL 10 dengan bobot rerata 0.01 g/ekor dengan padat tebar 1.500 ekor/m3 (18.000 ekor/bak) dan 2000 ekor/m3 (24.000 ekor/bak). Lama waktu pemeliharaan selama 28 hari. Selama pemeliharaan diberi pakan komersil dengan dosis 5%-10% dari total bobot biomassa perhari. Hasil penelitian menunjukkan panjang dan bobot akhir rata rata yang terbaik didapat pada perlakuan A (1500 ekor/m3) yaitu sebesar 5.15 cm dan 2.32 gram/ekor dengan nilai survial rate (SR) sebesar 89,7%.
