Abstract
Black Soldier Fly (BSF), Hermetia illucens L. is one of the common insects found in oil palm plantations. BSF can convert various organic materials into a variety of high-value products, such as sources of protein and fat for animal feed, and biofertilizers that are useful for plants. Urban organic waste (UOW) is one of the organic materials available abundantly and has a high potential to be converted by BSF. However, to optimize the ability of BSF as a bioconversion agent of UOW, additional information is needed, such as BSF feeding rate recommendations based on UOW material. This research investigates the optimal BSF feeding rate based on UOW (vegetable waste : fruit waste : restaurant food residue, 1:1:1), with variations in feeding rates of 100, 125, and 150 mg/larvae/day. The results showed that the optimal feeding rate for UOW material conversion was 125 mg/larvae/day, as evidenced by the highest value for efficiency of conversion of digested-feed (ECD) of 36.97 +/- 0.02% with final larvae weight 41.27 +/- 8.25 mg/larvae, dw, growth rate (GR) 1.38 +/- 0.23 mg/day, dw, and productivity 175.26 +/- 35.01 g/m2/day, dw.
