The government has regulated the use of RDF biomass for coal co-firing in power plants. This paper examines biomass (Eichhornia Crassipes and municipal solid waste) characteristics and its potential use as RDF for co-firing in CPP. The method includes the analysis of the composition, supply of raw materials, and biomass characteristics. These results will compare with the coal’s characteristics in CPP. The density of Eichhornia Crassipes in Lake Tondano was 25 kg/m 2 , with the wet mass of 45,350 tons. The results of the Eichhornia Crassipes sample test for parameters of moisture content, volatile matter, ash content, fix carbon and gross calorific value have a value range of 93%, 5.8-7.1%, 60.21-63.5%, 17.9-22%, 11.4% and 2681-3068 kcal/kg. Amurang CPP uses coal with 4200 kcal/kg calories as much as 1056 tons/day. The co-firing target of 5% requires 52.8 tons of biomass per day. The existing Eichhornia Crassipes biomass in Lake Tondano only supplies the CPP for 62 days. MSW typically has calorific values and moisture with Eichhornia Crassipes biomass, about 3766-4194 kcal/kg and 31.7-87.1%. The use of MSW to cover the lack of Eichhornia Crassipes will ensure the sustainability of the supply of biomass raw materials in the co-firing program at CPP.
