KONVERSI LIMBAH CAIR TAHU MENJADI GAS BIO MENGGUNAKAN AKTIVATOREFEKTIF MIKROORGANISME 4 (EM4)
Abstract
The objective of this study is to understand the feasibility of tofu liquid waste as a raw material of biogas, using additional materials of goat rumen and EM4 activator. The experiments were carried out in 5 batch reactors filled with 3000 ml waste and 300 ml rumen, and added with EM4activator varied for 0 ml, 25 ml, 50 ml, 75 ml and 100 ml. Based on our observations, it can be concluded that the addition of EM4in a batch process is positively correlated to the organicdecay of tofu liquid waste into biogas. The best result was observed in Reactor IV containing 75mlEM4where the biogas was produced after 72 hours.
