Analysis of biogas production made from oil palm empty fruit bunches (OPEFB) using anaerobic batch reactor (ABR)

This research aims to analyse the biogas production made from oil palm empty fruit bunches (OPEFB) using anaerobic batch reactor (ABR). In this study three factors were used and each had three levels. The first factor is source of microorganism (liquid waste and sludge of Palm Oil Mill Effluent, and P-Biored), the second factor is preliminary treatment using NaOH (concentrations of 0, 1, and 8) and the third factor is total solids (10, 25, and 40 ). The research parameters included the volume of biogas, levels of methane gas, and reduced organic matter. The results of this study indicate that the best factor and level are preliminary treatment with 0 NaOH, source of microorganism from liquid waste of Palm Oil Mill Effluent and using 10 total solids which produce as much as 2457 ml biogas with methane yield of 929.01 ml/300 gr OPEFB and reduced organic matter of 138.25 gr/300 gr OPEFB. © Published under licence by IOP Publishing Ltd.
