Waste minimization in the poultry industry through Black Soldier Fly larvae cultivation to improve the bio-conversion

Abstract Chicken manure or litter has great potential to serve as a substrate for black soldier fly (BSF) larvae, particularly in terms of its availability and nutrient composition. However, chicken manure substrate has lower substrate reduction and bioconversion values compared to other organic wastes in BSF cultivation. The study combined chicken manure and sausage waste derived from the poultry industry to enhance the substrate reduction and bioconversion values in the cultivation of BSF larvae. The BSF cultivation substrates, chicken manure and sausage waste, were supplied by PT Japfa Comfeed Indonesia, Tbk, while the restaurant waste was obtained from Rindu PIAT of Gadjah Mada University. Therefore, the findings could support the circular economy and the material of the poultry industry by improving the bio-conversion process. High substrate reduction and bioconversion were achieved at 63.5% and 58.7%, respectively. The high protein content (> 30%) of BSF larvae was produced during the cultivation process in this study, as indicated by the proximate analysis.
