Economical and technical analysis of Pangkalpinang waste power plant incinerator technology

Abstract Increased waste production has always been a problem for every city in Indonesia, including in Pangkalpinang. Population growth, inadequate processing, and utilization of waste are the primary causes of this issue. An alternative to reduce waste piles is to convert waste to fuel for waste power plants. To find out how much electrical energy potential in landfills and the feasibility of a waste power plant, an analysis is needed by calculating using existing formulas, forecasting with geometric methods, and investment assessment with NPV, IRR, and also the payback period. The calculation showed that the potential for electrical energy for 2013 was 6,661,924 kWh, while during the 2022 period was 13,161,362 kWh per year. The results of the forecasted waste potential for 2023 until 2033 increased the generated electricity. In 2023, the produced energy was 16,553,678 kWh/year. While in 2033, the amount of energy produced will be 21,190,137 kWh/year. Purchasing electricity from a waste power after being traded shows a sizable income. The construction of this waste power plant meets the feasibility considering the investment assessment made with a purchase price of electricity of more than IDR 1,600 per kWh.
