Black Soldier Fly (BSF) larvae are known to have the ability to decompose various types of organic waste. The sediment sludge of Dago Pakar Daily Reservoir Pond itself, which comes from a mixture of soil, domestic waste, and animal waste, can be categorized as organic waste, so it has the potential to be decomposed by BSF larvae, which can reduce waste and produce by-products of economic value. This study aims to evaluate the effectiveness of BSF larvae in converting sediment mud and measuring growth parameters and waste reduction. The research method uses measurements of larval mass, Waste Reduction Index (WRI) value, Efficiency of Conversion of Digested Food (ECD), Survival Rate (SR), and testing the content of BSF larvae and residues at the end of bioconversion. In this study, a treatment consisting of sediment mud and three other substrates was used, mixed with cabbage waste with a ratio of 1:1, 3:2, and 4:1. The results of the experiment showed that the best larval growth occurred when fed sediment mud mixed with cabbage waste with a ratio of 1:1 which had an average mass of 0.534 g/10 larva, a WRI value of 5.739%, an ECD of 0.403% and an SR of 83.8%. In addition, both BSF larvae and bioconversion residues have not been able to produce biomass and residues with high nutritional content that are safe for use as animal feed and organic fertilizer according to standards, so further processing is required.
