PENGGUNAAN LIMBAH BUAH MANGGA SEBAGAI BIOAKTIVATOR ALTERNATIF PADA PENGOMPOSAN SAMPAH BASAH

Abstract

The waste generated at Mergan Market is mostly piled up on the road or collected in communal trash bins placed within the market. The most common waste found at Mergan Market is vegetable waste. An effort to address the waste problem at Mergan Market is through composting. This study aims to determine the effect of adding bioactivators in the composting process to reduce waste at Mergan Market. This research uses the Takakura basket method. The variations in the doses of mango fruit bioactivator used are 250 ml, 350 ml, and 450 ml. The composting process lasts for 14 days. The analysis results show that all three dose variations have the same temperature of 30°C but different pH levels: doses of 250 ml and 350 ml have a pH of 6.9, while the 450 ml dose has a pH of 6.8. Differences are observed in the bioactivator with dose variations of 250 ml, 350 ml, and 450 ml, which have moisture content of 26.92%, 26.97%, and 28.73%, respectively. Organic carbon content is 15.64%, 15.66%, and 16.72%, respectively. Total nitrogen content is 1.16%, 1.19%, and 1.15%, respectively. The C/N ratio is 13.48, 13.16, and 14.54, respectively. All three compost dose variations have met the requirements of SNI 19-7030-2004.
