Quality of Cow Manure Compost Using Effective Microorganism (EM4) and Black Soldier Fly (BSF) Fly Larvae (Maggot)

Abstract

This study aims to determine differences in the quality of cow manure compost using Effective Microorganisms (EM4) and the quality of cow manure compost using Black Soldier Fly (BSF) Larvae (Maggot). The experimental design used in this study was a completely randomized design consisting of 4 treatments and 5 replications. Treatment Po = Cow dung, P1 = Cow dung + EM4, P2 = Cow dung + maggot, P3 = Cow dung + EM4 + maggot. Parameters observed were temperature, color, smell, texture and C-organic compost which showed a very significant difference (p <0.01) to the mean value of fermented cow dung, the lowest total N was found at p1 with a value of 0.69% while the highest value is found in p2 with a value of 1.13%, the lowest C/N ratio is found in p2 with a value of 36.97% while the highest value is found in po with a value of 63.54%, the lowest P2O5 is found in p1 1.42% while the the highest was at 2.45%. The lowest K20 is at p2 with a value of 1.41% while the highest value is at p3 with a value of 2.346%., and the lowest PH is at p2 with a value of 8.214% while the highest value is p1 8.72%.
