Penggunaan Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) untuk Simulasi Sebaran Polutan NO2 dan SO2

Abstract

HYSPLIT is a model primarily designed to predict the trajectory, dispersion, and concentration of pollutants from a single or multiple sources. The model may be integrated with meteorological data fields derived from the WRF model to identify source location. Industrial area normally release various types of gas pollutants with variable concentrations, including NO2 and SO2. The abundance of the emitted pollutants will increase along with increasing industrial activities. As part of air quality management, activities to monitor air quality needs to be conducted regularly in order to control the pollutants concentrations. Utilizing a model simulation may allow us to identify the pollutants exposure potentials. The objective of this study include to understand how HYSPLIT can be used to predict and analyze trajectory of pollutants, estimate pollutants concentrations, and analyze the relationship between temperature and atmospheric stability to NO2 and SO2 concentrations. The result showes that in June trajectory is directed westward and in December trajectory it moves eastward. In addition, NO2 concentrations obtained for PT. X ranged from 350.5 to 368 and SO2 ranged from 338 to 677 . The NO2 concentrations for PT. Y ranged from 385.7 - 410.2 and SO2 ranged from 442.2 - 401.1 Temperature and atmospheric stability conditions affect the concentration of pollutants significantly. Correlation between temperature and concentration of NO2 and SO2 ranged from -0.54 to -0.69 and the correlation between atmospheric stability and the concentration of NO2 and SO2 is -0.51 to -0.78.
