Analisis teknoekonomi usaha pengolahan limbah cair organik menggunakan black soldier fly (Hermetia illucens)

Abstract

Liquid waste could not treated by primary treatment only, secondary or tertiary treatment is needed. However, this process has a high cost, so alternative processes are required. Black soldier fly (BSF) is an alternative treatment for a low-cost. In addition, waste treatment with BSF also produce animal food from the larvae produced and compost from processing residue. This processing product has a good economical value. However, a business project should be conducted a feasibility analysis to find out if the business is possible. Feasibility analysis is based on financial analysis of investment criteria: Net Present Value (NPV), Net Benefit Cost per ratio (Net B/C), Internal Rate of Return (IRR) and Payback Period (PP). The result is NPV Rp141,626142; Net B/C 1.15; IRR 17.6 % and PP 3.95 years. Based on that financial criteria, the organic waste processing into animal feed and fertilizers using BSF is possible. Sensitivity analysis shows that decreasing revenue over 8.04% could make this business unfeasible. The increasing of main material cost for almost 59% could keep this business feasible.
