Abstract: This study aims to determine the pattern of dissemination, distribution model and estimation of SO2 and CO gas emission concentration derived from the Tello diesel engine with a dynamic model approach. The design of this research is descriptive quantitative with Gaussian Model approach and dynamic system model. The study was conducted at PLTD Tello Kota Makassar by collecting secondary data. For model distribution and estimation of SO2 and CO pollution using Gaussian Model and dynamic modeling with Stella. Population in this research is data of emission emission parameters generated by Tello’s steam power plant influenced by atmospheric stability, wind direction and velocity so as to obtain concentration of pollutant by using Gaussian calculation sample sample is SO2 concentration concentration and CO PLTD Tello contained in monitoring report on RKL&RPL implementation for 2012-2017. The results of the dominant area of research are the impact of pollution from the Tello diesel power plant based on the dominant wind direction during 2012-2016 is the Northwest part of the Tello steam power plant at a height of 1 m above the ground with a distance of 500, 1, 500, 2, 500 and 4,000 m of the Tello diesel powered TTL Aspol, Panaikang, Pampang and Rappokalling. Total SO2 and CO emission concentrations derived from Tello PLTD during 2012-2016 in each location at 1 m above ground level with a distance of 500 m, i.e., Aspir Tello SO2 1.395 and CO 1.162 μg/m3, a distance of 1,500 m of SO2, SO2 1.247 and CO 1.039 μg/m3 2,500 m distance of Pampang 0.878 μg/m3 and CO 0.7317 μg/m3 and a distance of 4,000 m of Rappokalling 0.6363 μg/m3 and CO 0.5303 μg/m3 from the pollutant source of the chimney PLTD Tello. The estimated concentration of Sulfur Dioxide (SO2) and Carbon monoxide (CO) gas emissions based on 12 month dynamic model simulation (2018) is increasing every time until July 2018 at each of four location points at 1 m above the surface soil with a distance of 500 m of Aspol Tello SO2 0.26065 μg/m3 and CO 0.21530 μg/m3, 1,500 m distance of Panaikang SO2 0.04447 μg/m3 and CO 0.03134 μg/m3, distance 2500 m of Pampang SO2 0.01760 μg/m3 and CO 0.00938 μg/m3 and a distance of 4,000 m of Rappokalling SO2 0.00740 μg/m3 and CO 0.00611 μg/m3 from the source of the bursts of the Tello steam power plant with the rate of increase in the emission concentration of Asp2 SO2 0.0053 and CO 0.0044 times, SO2 04061 times and CO 0.0004 times, Pampang SO2 0.00021 times and CO 0.000073 times and Rappokalling SO2 0.000078 times and CO 0.0000064 times every month. The concentration of SO2 and CO emissions generated by the Tello steam power plant during 2012-2016 is still far below the ambient air quality standard (South Sulawesi Governor Decree No. 69 Year 2010) in each location at a height of 1 m above ground level, i.e., Aspol Tello 0-1.39 μg/m3, Panaikang 0-1.247 μg/m3 Pampang 0-0.878 μg/m3 and Rappokalling 0-0.6363 μg/m3. So, it can be said that the four areas are still included in the air quality is quite healthy.
