One of the by-products of palm oil processing plants is Palm Oil Mill Effluent (POME) liquid waste. One of the palm oils mills (POM) that have the potential for the construction of a Biogas Power Plant is the Pagar Merbau Palm Oil Mill, owned by PT. PN II North Sumatra. This Palm Oil Mill has a processing capacity of 30 tons of Fresh Fruit Bunches (FFB)/hour and has utilized its liquid waste (POME) into electrical energy with the Covered Lagoon system. The Utilization of POME can produce methane gas 3600 Nm3 CH4/hour, or the equivalent of 0.575 MW. A power plant with a factory capacity of 30 tons of FFB/hour generally produces 1 MW of electrical energy. Therefore, to achieve its full potential, the power plant needed optimization by comparing the increase in electricity production and electricity sales to PLN. This review used literature studies to collect data related to Palm Oil Mill Liquid Waste characteristics and alternative anaerobic technologies and calculate each alternative potential for biogas utilization. The selected technology was carried out by weighting analysis using the Simple Additive Weighted (SAW) method. Up-flow Anaerobic Sludge Blanket (UASB) is the technology that has the most excellent weighting value and is the technology of choice. In planning this project, the expenditure was Rp. 2,401,454,202, and the operational cost was Rp. 3,121,434,712. This project is economically feasible based on the NPV (Net Present Value) analysis results. The results of the optimization analysis show an increase in electrical energy and the value of electricity sales, which is above 20%.
