Coal Steam Power Plan is nowadays very important because it serves electricity in certain areas in Indonesia. Mpanau Coal Steam Power Plan (Mpanau PLTU) located at Palu (Central Sulawesi, Indonesia) which is a source of electricity for the people who live in Palu and its surrounding area. The energy source of PLTU derived from coal which is a fossil fuel. The use of coal as an energy source creates some environmental problems such as the ash waste (bottom ash and fly ash). Characterization of waste ash from fly ash and bottom ash in qualitatively and quantitatively ways is the first step to evaluate the environmental impacts related to environmental and biological contamination risk. In this research, silica concentration (SiO 2 ) has been determined after separation method by extraction of both ashes from Mpanau PLTU. Silica concentration of bottom ash and fly ash sample was 21.31% and 29.85% respectively. Furthermore, the extraction silica was characterized by using Fourier Transmission Infra-Red (FTIR), X-Ray Diffraction (XRD), and Scanning Electronic Microscope (SEM) to see morphology.
