Coal-Fired Power Plant Teluk Balikpapan is a power plant located in the Kariangau Industrial Estate, Balikpapan, Indonesia, with a capacity of 2 x110 MWMW with coal consumption reaching 140 tons/hour or 3,360 tons/day. Besides generating electricity, burning coal also produces waste in the form of fly ash (fly ash/FAFA) and bottom ash (basic ash/BABA) with 150 tons and 18 tons, respectively. FAFA and BABA are waste from coal combustion from several studies state that FAFA and BABA can be used as supporting materials or substitutes for cement. Therefore, the Balikpapan Bay, which produces FAFA and BABA, has the potential to support the construction of the new National Capital. Research on FAFA and BABA of Teluk Balikpapan as a subgrade was carried out through the CBR (California Bearing Ratio) with 5 mixed compositions of FAFA, Cement, Aggregate, and Sand. The test results show that the Subgrade with a composition of 100% FAFA has a quality of 15.32%. These results show that FAFA and BABA have excellent quality and are in accordance with the standards to be used as supporting materials for developing the National Capital.
