In Indonesia, growing cassava based food production significant amount of cassava peel wastes which has huge potential to cause significant environmental and health problems. Studies had showed the ability of Black Soldier Fly (BSF) larva (Hermetia illucens) to live in various type organic wastes made them as one of potential biological agents for bioconversion of household, industrial, and agricultural organic wastes. wastes. In order to apply this insect as bioconverter of cassave peel wastes, some growth variabels of BSF fed on cassave peel wastes were measured. In this study, two hundreds 6-day-old larvae were fed on cassava peel with a variation of 12.5, 25, 50, 100, and 200 mg/larva/day, replicated three times, until pupation. Results showed negative relation betweenfeeding rate and proportion of substrat consumption while negative relation recorded between feeding rate with efficiency of feed conversion. Highest propotion of feed used for metabolism recorded at lowest feeding rate. Best waste reduction index (2.79 ± 0.15), development time to pupation, and feeding duration recorded on feeding rate of 100 mg/larvae/day. Based on this study, it could be concluded best feeding rate for growth of BSF larvae is 100 mg/larvae/day.
