Abstract
Numerical convection and diffusion models can be used to predict air pollutant concentrations in an area. Changes in air pollutant concentration can be analyzed using diffusion equations which depend on the coefficient of intra-particle diffusivity (D). Whereas to find out the changes in air quality categories become polluted using a convection equation which depends on the diffusivity coefficient between particles (Γ). The combination of the two equations can be used to estimate the polluted areas of a region. The results of the climate analysis indicate that Banten Province if viewed from the direction of the wind, is very potential for the development of increased fish production. Meanwhile, if viewed from the temperature and rainfall of Banten Province the potential for agriculture. However, considering that in the western part of the region there is a large industry with a chimney height of 275 meters, so based on atmospheric stability, the distribution of air pollutants spread far outside the industrial area. This will have implications for other regions so that at high concentrations (with diffusion equations) it will change the air quality (with the convection equation) so that in certain regions and at certain times it will become a polluted area.
