This study is a comparative study of fuel use at 2x7 MW Ropa PLTU plants using the cofiring Refused Derived Fuel (RDF) method sourced from Biomass and full Coal. Discussion around Thermal Efficiency at the time of Cofiring RDF batubara Coal and Core Cost of Production (BPP). This study analyzed thermal efficiency with output calorific equation divided input calorific and calculated Specific Coal Consumption (SCC) to obtain production base cost (BPP). From the results of Analysis of RDF-Batubara cofiring usage having output calorificity of 7.38 MW, PLTU boiler efficiency at the time of cofiring 26%, PS ratio 13.9%, SCC 1.1 kg/kWh, netto heat rate of 5,136.9 Kcal/kWh, and Rupiah core cost of 76.75 kg/kWh. On the other hand, the use of Full Coal calorific output amounted to 5.9 MW, boiler efficiency 29%, PS ratio 12.8%, SCC 0.72 kg/kWh, Heat Rate 3,267.8 Kcal/kWh, and Core Cost of Production (BPP) 511.64 Rp/kWh. The conclusions obtained after conducting the analysis were that the use of RDF-Batubara cofiring fuel decreased boiler efficiency by 3%, increase in Specific Coall Consumption (SCC) by 0.38 kg/kWh and increase in production base cost (BPP) by 254,114 rupiah/kWh. CO, NO and NOx emissions are high yet Greenhouse Gas (GRK) emissions are low.} }
