Air pollution is one of the impacts that must be concerned by Gresik Power Plant. The presence or absence of pollution can be seen in the ambient air quality around the plant location which is routinely monitored every six months. However, the monitoring data is not representative because there is no daily data conducted. Therefore, emission dispersion modeling can be carried out to obtain ambient air conditions around the plant site. In this research, the modeling is carried out using Gaussian Analysis for the HRSG chimney 3.1 and it can be seen that the area around the power plant and Pulopancikan village are significantly affected. This is indicated by the presence of a red zone in the results of the modeling and the concentration of NO2 pollutants can reach 892.65 µg/m3 exceeding the government standard (150 µg/m3). However, the validation of the model shows significant gap due to some circumstances such as meteorology condition, vehicles pollution, and human activities. In consequence, such a modeling can be developed further. For instance, the study needs to forecast emission dispersion of all active chimneys on the site in order to capture environmental condition and more concern to meteorology condition and other pollution sources.
