Abstract

According to National Medium-Term Development Plan set a target of 35,000 MW in 2019, where in 2016, coal still dominated the power plant^s fuel, which is 62%. For the renewable energy namely gas and oil fuel, the contribution is 17% and 5 % respectively. The fastest rate of consumption is 4,7% per year since 2002, thus by the domination of coal-fired power plant in Indonesia in 2005 with 29.4 million tons of coal consumption, it is projected that there will be an increasement in 2020 with 75 million tons of coal consumption. This condition could lead into generation of coal dust which potentially impact to the ground concentration of TSP in the ambient air quality. Further impact may lead into environmental & social issue in the community residence of surrounding coal-fired power plant (PLTU). Considering the potential impact of coal dust emission from coal stockpile activities, study of prediction Coal dust dispersion which generated from coal handling activities to determine the ground concentration of TSP in is necessary to lead of determination for appropriate mitigating control to reduce the coal dust emission. Therefore, the existence of such power plant will have mutual benefits with surrounding area, especially the community. According to the model prediction result using AERMOD it could be predicted that the emission contribution from the coal stockpiles is reach 100-200 &#956-g/m3.
