PEMANFAATAN BAKTERI INDIGENUS SEBAGAI EFFECTIVE MICROORGANISM (EM) UNTUK MEMPERCEPAT LAJU DEKOMPOSISI SAMPAH ORGANIK

Abstract

Recycling of organic waste is important because it can reduce environmental problems. Composting is the alternative method for waste recycling, but naturally, the processes always waste a time. EM technology is proven to decrease the composting time. This research conducts the isolation for 3 kinds of indigenous bacteria from compost that used for liquid EM production. The yield of isolation process are 3.6x109 cfu/g phosphate degrading bacteria, 5.6x109 cfu/g cellulose degrading bacteria and 2.7x109 cfu/g nitrogen fixing bacteria. The medium are used for this study to make EM contain of aquadest, 25% sugar cane fresh liquid and 2% Nitrogen-Phosphor-Potassium mixing fertilizer. The final EM product contain of 8.2x108 cfu/g mixing bacteria. The solid starter production with liquid EM addition needs 14 days. The final solid starter has brown color and smell like soil, roughly texture but break up, 7.8 for pH average and 33.8oC for temperature average. In other hand, fresh compost production need 22 days. Further more, in final process, the fresh compost has black-brown color and smell like soil, smoothly texture and crumbs, humidity decreasing, 7.4 for pH average and 44.5oC for temperature average.
