Abstract

Sheep solid waste in feces can be processed and converted using indigenous microorganisms and the Black Soldier Fly (BSF) maggot detritivore. The results of the decomposition of organic material from sheep feces can be BFS maggot biomass and BSF frass. The research involved combining sheep feces with milk processing industry sludge and organic kitchen waste and aerobically processing them using indigenous microorganism decomposers and BSF maggot detritivores. This research aims to convert sheep feces into BSF maggot and BSF frass biomass using various waste materials, indigenous bacteria, and fungi using exploration methods. The method used was exploration, and data was obtained in a descriptive. Beginning with a 7-day initial decomposition process by microorganism decomposers, the process of processing sheep feces then continues for 21 days by maggot detritivores. The research showed that indigenous bacteria and fungi in the substrate amounted to 5 × 10¹⁰ cfu/g and 3 × 10⁵ cfu/g. Processing sheep feces could reduce the amount of waste, which resulted in a reduction of 63,87%, resulting in BSF maggot biomass of 1042±98.4631 g and Frass BSF of 1084±55.8345 g.
