Air pollutant dispersion modeling is often applied as a decision support tool in air quality control and emission reduction. The CALPUFF application is a non-steady state Gaussian puff dispersion modeling software that operates in the Lagrangian coordinate system. Pollutant dispersion modeling in CALPUFF depends temporally and spatially on various emission, geophysical, and meteorological parameters with various computations in it. Sensitivity tests were carried out on modeling in order to identify the effect of input parameters on the modeled output of pollutant concentrations so that control strategies can be applied to these input parameters. The modeling was carried out at the chimney point source of the sugar factory X in Glenmore sub-district, Banyuwangi district, which emits particulate dust pollutants in large quantities compared to other pollutants. Based on the sensitivity analysis carried out, the order of sensitive parameters in reducing the maximum pollutant concentration modeled are reduction in emission load (sensitive; 99.894), increase of ambient air temperature (quite sensitive; 59.662%), enlargement of the inside diameter of the chimney (not quite sensitive; 31,432%), increase of the height of chimney (not sensitive; 24,745%), and the increase of exit gas velocity from chimney (not sensitive; 17,232%), can be considered by the owner of factory X in optimizing the dispersion of pollutants in the atmosphere.
