Producing feed protein by bioconversion of domestic and industrial organic solid wastes using Black Soldier Fly (BSF) larvae

Abstract

The bioconversion of organic solid waste utilizing Black Soldier Fly (BSF) larvae was used to reduce the unstable domestic supply of feed protein in Indonesia due to currency change dynamics. BSF larvae are a well-known bioconversion agent capable of producing high protein content in their body mass. Therefore, this research aims to conduct a small-scale bioconversion process of domestic and industrial organic solid wastes to produce dry BSF larvae as a protein source for chicken and fish culture. The research was held at Bogor, Indonesia, from March-June 2021, where organic solid waste from a restaurant was bioconverted by BSF larvae in a biopond. After two weeks, the BSF larvae were harvested, dried, and milled to produce the powder. Based on SNI 7548:2009, the quality of pellets from BSF larvae and pupae was appropriate, except for the parameters of fat content in pellet A and water and ash content in pellet B. The results showed that fish pellets mixed with 20% protein flour affected the weight growth of Pangasius sp. Furthermore, when dried BSF larvae powder was applied to one-day-old chickens, they grew somewhat quicker than the standard feed menu. Therefore, organic solid waste, when appropriately managed, produces feed protein.
