The development of larva production of Patin catfish has great potential to meet market demand. CV Mika Distrindo is the one of company that need a development strategy to increase production to meet demand of Patin catfish larva. The aims of this study were: (1) to obtain information on the production process of breeding; (2) to know the feasibility of breeding; and (3) to carry out the strategy of seeding to obtain maximum profit. Method of analysis was done with (1) a descriptive analysis of the production process for a portrait Patin catfish hatchery; (2) Analysis of the feasibility using NPV, IRR, Net B/C Ratio, Gross B/C Ratio, PBP, and BEP; (3) Analysis of internal and external matrix are using IFE and EFE matrix, and in combination in a matrix of IE; 4) SWOT matrix analysis to formulate strategic alternatives; and 5) Analysis QSPM for alternative decision priorities. The study results shows that CV Mika Distrindo is feasible because the business get the financial benefit. Indications in terms of financial feasibility are known from Rp516.660.510 of NPV; 21.42% of IRR; 5.57 of Gross B/C Ratio; 4.05 of Nett B/C Ratio; 10 months and 5 days of PBP and 2.698.006 of larva production or Rp539.601.139,60 of the value of sales. IFE score is 2.511 and EFE score is 2.565 (medium position). The Company core strategy is Growth/Stability Strategy. The SWOT analysis obtains formulation of strategies including the use of advances in technology, expansion of marketing network, strengthening capital, increasing sales volume, doing partnerships, taking advantage of investors, increase customer loyalty, maintain larva quality, improved system management and collaboration with stakeholders.Key words: Patin catfish hatchery, feasibility analysis and business development strategy

<p>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.</p>

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 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.
