I In Cibodas Village, there was a build-up of agricultural waste in the form of cassava peels due to the unavailability of Waste Management Sites (TPS). Besides cow dung is also a problem in this village because most cow dung is thrown into the river. This study aims to plan the utilization of cow manure and cassava peel waste into organic fertilizer using the vermicomposting method by considering the factors that influence the process of bioconversion of waste, worm biomass and the quality of the fertilizer produced. Vermicompost technology in this study uses an earthworm type Eudrilus eugeniae. The results of this study were the highest bioconversion in the treatment of 50% cow dung, 50% cassava peel with abioconversion value of 56% and a treatment at a density of 1,5 kg/m2. While thelowest bioconversion rate was in the treatment of 30% cow dung, 70% cassava peel with a bioconversion value of 38% and treatment at a density of 2 kg/m2. This shows that stocking density in the composting process of vermicompost affects the process of bioconversion of organic waste into compost. In the growth of worm biomass, the highest value is in the treatment of 50% cow dung, 50% cassava peel with a biomass value of 147 grams and is a density treatment of 2 kg/m2. While the lowest level of bioconversion is in the treatment of 100% cow dung with a biomass 29 grams and a treatment of 1,5 kg/m2 density.
