Feasibility Study of Biomass Power Generation System Using Comparison Analysis

Waste treatment becomes one of the world's concentrations for improving sustainability in the energy sector in both developed and developing countries. Indonesia is one of the developing countries that conduct waste management for becoming a country with a sustainable environment. Waste management is a very important implementation system for upcoming on the excess supply of waste. Population growth is one of the factors that cause an increased supply of waste in some cities in Indonesia. Therefore to give a good impact, waste management needs to be done by local government or municipal governments. In its implementation, the governor established a policy to select the technology to manage waste by appropriate methods to determine the technology. Waste projection of Pematangsiantar City about 42,608,487 kg per year is used as base data in case study management of waste that will be formulated on the biomass power generation. This study, implementing comparison methods on the assessment of appropriate technology to solve the waste problem of the city using better technology. The selected waste treatment technology in this study are incinerator, pyrolysis, and anaerobic biodigester technology. The results show that the technology of anaerobic biodigester is feasibly applied based on the value of payback period (PP) for 4.1 years, average rate return (ARR) for 3.08%, and average produces the lowest carbon dioxide in 1,273.48 Gg per years.
