【 摘 要 】

Indonesia as the largest producer of palm oil in the world has the prospective to generate additional benefits such as electricity by utilizing Palm Oil Mill Effluent (POME). The high Chemical Oxygen Demand (COD) content of 35,000 ppm POME is a great potential for conversion to hydrogen and methane through a fermentation process. In this study, two stages of fermentation using a microbial consortium have been performed in the 1 m3BioHythane reactor system to produce biohydrogen and biomethane. After two-stage fermentation process for 24 hours in this system, the microbial consortium succeeds in producing biohydrogen and biomethane of 32 and 60 vol. %, respectively. This gas product after the purification process could be converted to electricity to be 0.02 and 0.75 kWe, respectively. Furthermore, as result of economic calculation analysis, this biohythane system showed up the value of Capital Expenditures (CAPEX) of US $ 26,39540 and Operating Expenses (OPEX) of US $ 14,712 per year, and resulted total generated electricity cost of US $ 2.478 / kWh.
