KELAYAKAN TEKNO-EKONOMI PLTSA INSINERASI 10 MW DI TPA TERJUN KOTA MEDAN

Abstract

Medan City faces increasing waste generation that has pressured the carrying capacity of the Terjun landfill and created the need for a more sustainable treatment option. This study analyses the techno-economic feasibility of a 10 MW waste-to-energy incineration plant at the terjun landfill by comparing moving-grate, fluidized-bed, and rotary-kiln technologies. A quantitative secondary-data approach was used to asses waste generation , waste composition, energy potential, and financial indicators including NPV, IRR, benefit-cost ratio, payback period, and sensitivity analysis. The result show that medan has sufficient waste supply to support plan operation. Moving-grate provides the highest annual power output and feasible financial performance, while rotary-klin record the highest NPV under less realistic city-scale CAPEX assumptions. Revenue is the most sensitive variable. overall, moving-grate is the most realistic option for the terjun landfill context
