Cultivation of Black Soldier Fly Larvae (BSFL) is a potential solution to Indonesian waste problem. BSFL can convert organic waste into valuable bioproducts such as high-protein biomass, organic compost and liquid fertilizer [1-4]. The protein content of BSFL can reach between 40-60% while the fat content range between 20-30%. The nutrition content of BSFL make them suitable for animal feed such as birds, chicken, or fish. Controlled microclimate condition and space requirement are among the challenges in the cultivation of BSFL. Hence, a suitable rearing container has been designed to overcome such challenges by having a space-effective container equipped with sensors (temperature, relative humidity and light intensity) that is suitable for small scale household rearing. Cultivation of BSFL was carried out in rearing containers equipped with sensors. The cultivation was carried out at different aeration rate in a screen house in Labtek 1A, Jatinangor. The harvested biomass was analyzed to determine the composition of protein and lipid in the biomass. The harvested larvae were dried and crushed to form a powder before used as a main component to produce fish meal. The fish meal was provided as the only meal to goldfish and nile tilapia in an aquarium scale for 1 month. The conlusion is cultivation of black soldier fly larvae was carried using tofu and coconut residue in rearing containers equipped with sensors. After cultivation for approximately 1 month, the larvae were harvested and analyzed. The harvested larvae contain approximately 32% fat and 6% protein. Major fatty acid includes lauric acid (62%) and myristic acid (9%) whereas essential amino acid includes leucine (8%) and lysin (7%). The larvae were valorized to produce fish meal and used as the only feed for the cultivation of goldfish and nile tilapia with a relative growth rate of 0.14-0.55 g/day.
