Abstract :
Environmental pollution due to waste will be increasingly worrying. But at the same time there is less and less available fossil energy, so humans must change trends in the production and use of fuels, from fossil fuels to non-fossil fuels or new renewable energy. So that a concrete solution is needed, namely the construction of a waste power plant to replace fossil fuels. Waste that is considered to be the source of the problem turns out to be processed into garbage pellets and has a high heating value of 3,802 Kcal / Kg (Tekmira laboratory test results). The heating value is equivalent to the heating value of young coal, so that waste can be used as fuel to replace the fossil energy. In the feasibility study, the use of waste in the thousand islands to be used as a power plant for pellet waste on Tidung Island requires 4 units of Trillion Gasifier (TG180) and 2 units of C399 caterpillar generator with an output of 600 kW. PLTSa with waste pellet fuel is considered more efficient and feasible to build because with an investment of Rp. 7,774,448,900, - with the selling price of electricity Rp. 1,150 per kWh and bank interest of 12% per year yields NPV 2,543,228,560, IRR 19,712%, BCR 1,327 and PBP 4 years and 7 months. So the use of waste pellets as Downdraft gasification fuel PLTSa is very feasible to be built on Tidung Island
