Dispersion Modeling of SO₂ and NO₂ Emissions Using AERMOD on Ambient Air Quality at Steam Power Plant PT.X in Southeast Sulawesi, Indonesia

This study aims to analyze SO2 and NO2 concentrations around the PT.X power plant through direct measurements, model their distribution patterns using AERMOD, and evaluate the model’s performance using RMSE, MBE, and R statistical tests. Monitoring was conducted at two monitoring points (PLTU PT.X Area and Nii Tanasa V...

Roadside PM10 concentrations in relation to traffic volume and meteorological conditions in Makassar, Indonesia

This study aimed to quantify the combined influence of traffic activity and meteorological conditions on roadside PM₁₀ in Makassar, Indonesia, and to evaluate whether an integrated model provides better predictive performance than traffic-only and nonlinear alternatives. Field measurements were conducted at 30 roadside...

An Empirical Assessment of Traffic Volume Influence on Roadside NO₂ Concentration: A Micro-Scale Statistical Analysis in Makassar, Indonesia

Rapid urban motorization in Makassar has intensified roadside exposure to traffic-related pollutants. This study empirically evaluates the direct statistical relationship between traffic volume and roadside nitrogen dioxide (NO2) concentration along a major arterial corridor. Field measurements were conducted during th...
