Abstract: This research aims to estimate the concentration of Sulfur dioxide (SO2) and Ozone (O3) in the next 10 years on the main roads of Makassar and evaluated effectiveness the model concentration of Sulfur dioxide (SO2) and Ozone (O3). This research used an observational descriptive study with system dynamic models. The research was conducted on eight main roads at Makassar city with using purposive sampling method. Data analysis was the analysis of dynamic system using the program Stella. Dynamic modeling was started with flowchart model. The results showed that in 10 years from now, the estimated concentration of Sulfur dioxide (SO2) in the absence of control measures increased by 6286 mg/Nm3 with a multiple increase in concentration of 0.03 times/month whereas the estimated concentrations of Ozone (O3) in the absence of control measures increased by 4358 mg/Nm3 with a multiple increase in the concentration of 0.15 times/month. An increase in the estimated rate of SO2and O3 concentrations can be reduced through policy intervention to a concentration of SO2fell by 2675 mg/Nm3 with an increase of 0.1 fold and O3 concentration decreased by 1815 mg/Nm3 with an increase of 0.06 times/month. The most appropriate in reducing the rate of increase in the concentration of SO2 and O3 is the combined simulation (scenario 2-4).
