The growth of agro-industry such as palm oil, sago flour, and tapioca flour is directly proportional to the increase of waste production, so it requires action to prevent excessive pollution. One solution that can be done is to treat agro-industrial waste by utilizing bioconversion agents such as Hermetia illucens L. (Diptera: Stratiomyidae) or Black Soldier Fly (BSF) that can reduce organic waste. The purpose of this study was to determine the effect of feed variations from agro-industrial waste on the growth of BSF larvae and the rate of waste conversion by BSF. Larvae were cultured in plastic containers with a volume of 500 mL (D: 11.5 cm; t: 8 cm) containing 100 larvae per container and tested with four treatments, namely the provision of palm oil waste in the form of palm kernel meal (BIS), waste sago flour (OR), tapioca flour waste (OS) or commercial chicken feed (PAK) as controls. Observations were conducted every three days with the parameters measured including the average weight of BSF larvae, growth rate, feed conversion ratio (FCR), waste reduction index (WRI), and efficiency of conversion (ECD). The results showed that the PAK treatment resulted in the highest growth of BSF larvae with an average weight of BSF larvae of 99.98 mg and a growth rate of 1.55 mg/day. While the effect of the conversion rate on product waste varies with the highest WRI obtained in the BIS treatment, low FCR in the PAK treatment, and the highest ECD in the PAK treatment. Based on the results of the study, it was concluded that PAK treatment had a better effect on BSF growth, however, BIS could be used as BSF feed.
