Simulasi Penyebaran dan Persentase Fatalitas Oleh Gas SO2 dan CO2 Hasil Pembakaran PLTU Independent Power Producer (IPP) Lombok Timur (50 MW) Dengan Low Rank Coal Menggunakan Model Gaussian

The Sembelia Steam Power Plant is located in East Lombok, West Nusa Tenggara and is managed by PT. Lombok Energy Dynamic uses the light coal until 200,000 tons per year. This case can be the  environmental pollution. This study aims to calculate the SO2 and CO2 exhaust gases into the environment by the simulation as well as included the  fatality percentage due to coal combustion of the The Sembelia Steam Power Plant with the model of Gaussian. This research was carried out by calculating the SO2 and CO2concentrations released concentration. At the end of these project, we calculated the SO2 and CO2 released by the dispersion potential and fatality percentage at four points around it. The result of this research showed that the dispersion mass of SO2 dispersion was 0.096 kg per second (with distance of 2,000 to 46,000 m). This result showed that the increases (6.876x10-46 ppm to 1.276x10-5 ppm), and then showed that the decreases to 0 ppm. Fatality percentage in this study is 0 percent. The potential of  CO2 dispersion with an outgoing mass of 8,252 kg/second increased (2,000-58,000 m) with a concentration of 62.47x10-63 ppm to 7.9x10-4ppm. In the other hand, the concentration of CO2 was reduced to 0 ppm. In the end of this study showed that fatality percentage by the CO2 released is 0percent, and the calculation of dispersion at four points around the The Sembelia Steam Power Plant is safe from the SO2 and CO2dispersion.
