Background and Objective: Air pollution from cement industry produces nitrogen dioxide (NO2) and sulfur dioxide (SO2) pollutants which are dispersed into the settlement areas due to the influence of meteorological factors. This study aims to estimate NO2 and SO2 concentration from the stacks to settlements around of PT. Semen Tonasa area as the baseline data with the scenarios of mitigation measures to control both Pollutants.
Methods: This type of research is a descriptive observational with dynamic model approach. Model simulation is done as exiting condition and the scenarios were created. and stack height addition scenarios. The concern parameter is the ambient air quality around settlement PT Semen Tonasa area. The existing air quality concentrations at 6 receptors were carried out. The sampling technique was carried out by pre-post gravitational method for PM2.5 or chemiluminescence techniques for NO2.
Results: The results showed that estimation of NO2 and SO2 concentrations in the next 10 years (2018-2028), the highest at Taqwa Mosque was 116,87 µg/m3 for NO2 and at Bontoa was 13,44 µg/m3 for SO2. Based on the model of stack height addition scenario simulation results, the effectiveness of NO2 and SO2 concentration reduction was 98% and 97%, respectively.
Conclusions: The results of this study can explain the reduction of concerned gases concentration. This study can help in taking decisions on NO2 and SO2 emissions control from industry with a stack height addition to The reducing the concentration of NO2 and SO2 in the future.
