Analysis of Organic Waste Decomposition and Quality of Organic Fertilizer Using Earth Worms and Black Soldier Fly (BSF)

Organic waste for organic fertilizer is needed to increase soil fertility.This study aims to analyses the organic waste decomposition and the quality of organic fertilizer using earth worms and Black Soldier Fly (BSF) produced by Anyar Sari Market.The research used was a simple randomized block design with 9 treatments, namely P0, P1, P3, P4, P5, P6, P7, and P8 which repeated 3 times.Samples that have been weighted were put into the place of manufacture of organic fertilizer mixed evenly with cow manure and chicken manure according to the treatment.Earthworms and BSF larvae were stocked according to treatment after the media was 14 days old with 50% humidity.The parameters were the characteristics of organic fertilizers, levels of odor and structure of organic fertilizers, water content of organic fertilizers, percentage of weathering, and pH of organic fertilizers.The treatments had significant effect on observed parameters.The decomposition rate of P4 treatment increased by 67.66% compared to P0 which was only 27.67%.The suggestion was to use earthworms and BSF larvae by to accelerate the decomposition of the organic waste and to improve the quality of organic fertilizer.
