Prediction of coal dust dispersion to total suspended particulate (TSP) concentration in ambient air quality, case study: PLTU Tanjung Jati B

Abstract

According to the National Medium-Term Development Plan set a 35000 MW target in 2019, wherein 2016, coal still dominated the power plant's fuel, which is 62%. The fastest rate of consumption is 4,7% per year since 2002; by the domination of coal-fired power plant in Indonesia in 2005 with 29.4 million tons of coal consumption, it is projected to be an increment in 2020 with 75 million tons of coal consumption. This condition could lead to generated coal dust, potentially impacting the ground concentration of TSP in the ambient air quality. The further impact may lead to environmental & social issues in the community residence of surrounding coal-fired power plants (PLTU). Considering the potential impact of coal dust emission from coal stockpile activities, then the prediction of coal dust dispersion generated from coal handling activities to determine the ground concentration of TSP is necessary to determine appropriate mitigating control to reduce the coal dust emission. Therefore, such a power plant will have mutual benefits with the 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 reached 100-200 μg/m3
