Abstract

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.

Abstract

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

Abstract

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.

Abstract

Ikan gurame merupakan jenis ikan konsumsi yang banyak diminati. Akan tetapi dalam budidaya memiliki kendala yaitu pertumbuhannya yang lambat. Salah satu pemecahan masalahnya adalah dengan pemanfaatan probiotik pada pakan. Probiotik merupakan mikroba hidup yang bersifat menguntungkan dan memberikan dampak bagi peningkatan keseimbangan mikroba saluran usus ikan dan memperbaiki kualitas air. Dosis probiotik yang diberikan 4ml/1 kg pakan dengan cara menyemprotkan ke permukaan pakan yang diberikan. Sebelum dilakukan penyemprotan, bakteri probiotik dicampurkan dengan molase 100 ml dan air tawar sebanyak 12ml kemudian disemprotkan ke 1 kg pakan yang kemudian di kering anginkan. Pemeliharaan benih ikan gurame dilakukan di kolam beton ukuran 3x1 m dan padat penebaran perlakuan yaitu 60 ekor/m2 yang dipelihara selama 40 hari. Benih gurame diberi makan 3 kali sehari sebanyak 5% dari bobot biomassa. Selama pemeliharaan hasil pertumbuhan yang didapatkan yaitu pertambahan panjang dari awal tebar 3,93 cm sampai panen 6,60 cm. Pertambahan berat dari 2,85 g sampai 5,75 g. Laju pertumbuhan panjang harian mencapai 0,3-2,8%, nilai FCR (Food Convertion Ratio) 1,8 serta tingkat kelulusan hidup ikan gurame mencapai 53,5%.

Abstract

The content of organic matter can affect the growth of silk worms (Tubifex sp.). In addition, media porosity can also have an effect. This study aims to determine the effect of porosity on the cultivation of silk worm by using media of mud and sandy mud. The analysis used a complete randomized design method with three replications. The silk worm population in mud and sandy mud is 521 and 984, with ABW (Average Body Weight) growth of 0.3 mg and 0.1 mg. These results prove that porosity affects the population, whereas organic matter affects the weight of silk worms. So it can be concluded that the use of sandy mud media produces a higher population, but has lower ABW than the mud media.

Abstract

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.
