Abstract

Pengomposan domestic biowaste dan leachate dijalankan dalam kondisi anaerob dengan sistem batch. Proses dijalankan dalam 3 set komposter dengan volume yang sama namun perbandingan komposisi bahan baku yang berbeda. Tujuan penelitian ini adalah mengkaji proses pengolahan domestic biowaste dan leachate dalam proses pengomposan. Hasil yang diperoleh, penambahan leachate dapat mempercepat proses pengomposan karena leachate mengandung sejumlah mikroorganisme yang dibutuhkan dalam proses pengomposan. Selain itu, leachate juga mengandung senyawa xenobiotik. Oleh karena itu penggunaan leachate dengan kadar 50% memberikan hasil lebih efektif jika dibandingkan dengan penggunannya dengan kadar 100%.Kata kunci: leachate, domestic biowaste, pengomposan, anaerob

Abstract

Vinase anaerobic treatment is a one alternative process to treating vinasse. Microaeration is a one of process modification in anaerobic vinasse digestion that can improve the acidogenic performance. In this paper presents the influence microaeration in anaerobic vinasse treatment in kinetics aspect. The kinetics aspect was develop to approach and quantifying the effect of microaeration in anaerobic vinasse treatment systematically. Extract of cow dung was used as inoculums and vinasse 100 ppm as a substrate. Laboratory experiments using 4L vertical reactor (UASB) was conducted in 28 days and performed in batch recirculation mode. During the experiment, dosing air in different concentrations was injected in the slurry phase into different anaerobic digesters once a day. The variation of air concentrations are 0 L air/L feed; 0.5 L air/L feed; and 100 L air/L feed. As the result, the addition of 0.5 Lair/L feed could increase biodegradability (k=-5.7239) and accelerate acidogenesis phase (?m1=2.03/day) that can be proven by the percentage of VS removal reaching up to 77% and cuts the lag phase (?=1.028 days) and HRT making it shorter.
