Pemanfaatan Sludge Instalasi Pengolahan Air Limbah Domestik PDAM Tirtanadi dengan Menggunakan Larva Black Soldier Fly (BSF)

Abstract

Domestic sludge is solid waste generated from wastewater treatment plants that are generally unutilized and left in sludge-drying bed units. The purpose of this study was to analyze the potential value of reducing decomposition (waste reduction index / WRI) of domestic sludge using black soldier fly larvae (BSF / Hermetica illucens), proximate content (protein, fat and water content) in larvae and macronutrient content N- Total, P, K in castgots. Variation treatment consists of 25/75 grams, 50/50 grams, 75/25 grams and 100 grams of a mixture of domestic sludge and rice waste. The results of each treatment have the highest value (WRI) of 60%. At the highest protein content of 10.48% with 100 grams of sludge treatment, the highest fat content in 75/25 grams treatment of 4.12%, and the highest water content in 75/25 grams treatment of 4.17%. In macronutrient analysis, castot has the highest N- Total value of 0.11% in 100 grams of sludge treatment, the highest P value of 0.02% and the highest K of 0.60% in the 75/25 gram variation.
