Abstract
Abstract. Coffee husk is a lignocellulosic material that is abundant and can be used to produce biogas. This study compared biogas produced by using coffee husk as a substrate and adding rumen fluid and a mixture of rumen fluid and cow dung. This experiment was conducted for 30 days in an anaerobic batch reactor with a reactor working volume of 3.6 L at mesophilic temperature. The parameters tested in this study were the lignocellulose content of coffee husks, total solids (TS), volatile solids (VS), volatile fatty acids (VFA), chemical oxygen demand (COD), and the content of biogas produced from the two variables. . The values of Total Solids and Volatile Solids for the two variables are CR of 42.47% and 44.49% and CRC of 57.59% and 30.59%, respectively. The VFA values for both variables were 0.96% (v/v) for CR and 1.32% (v/v) for CRC. The COD values for the CR-R and CRC variables were 28.03% and 48.92, respectively. The methane yields for the variables CR and CRC, were 0.01 Nm3/kgCODremoval and 0.06 Nm3/kgCODremoval respectively. Keywords : coffee husks, cow dung, rumen fluid ,methane, volatile fatty acid.
