Abstract
The organic waste issue in Jakarta must be immediately addressed because it can harm the environment. Jakarta produces organic waste reaching 45.43% of the total waste generation with organic waste reduction of effectiveness only 4,981 tonnes/year (+1%). One solution to process organic waste is to use black soldier fly (BSF) larvae as decomposers of organic matter. The research examined the effect of bioconversion time/duration for household and market waste in Jakarta on bioconversion efficiency. The research was carried out by opening biopon samples each containing 2 kg of organic waste which were given 11.2 g of BSF 7DOL (day of life) larvae, varied with the duration of bioconversion, including 7, 12, 14, 17 and 21 days. The results demonstrated that the optimal time for the bioconversion process for household foodwaste and market waste was 12-14 days. It was based on the value of the bioconversion process efficiency indicator, which achieved the highest score for theEfficiency of Conversion of Digestedfeed(ECD) value on the 12thday and theoverall reduction(D) indicator on the 14thday. The low RGR and WRI values on the 17thand 21stdays also implied that the bioconversion process was not optimal
