Sustainable development in urban areas cannot be separated from environmental qualities, one of which is air quality and pollution. The target of reducing air pollutants can be pursued with policies that are following strategic studies. The system dynamics function as a tool for this study to analyze the relationship between the variable sources of pollutants and get the most likely scenario to be applied in Depok City until 2040. The system dynamic phases in this study include causal loop diagrams, stock and flow diagrams, and scenario simulations. There are 3 related net flows, air pollution level, private vehicle travel rate, and public transportation growth rate. The public transportation system development scenario can be applied in the city of Depok, since it can reduce the number of trips using private vehicles and can increase regional income. Although this policy can only be implemented in the next few years, the simulation results show the direction of stability. This means that in 2030-2040 the concentration of air pollutants can be removed if the population has consistent awareness.
