Abstract

Background: The increase in urban population and the growing number of motor vehicles contribute significantly to air pollution. High emissions of nitrogen dioxide (NO₂) from motor vehicles pose significant risks to health. Objective: This study explored the NO₂ dispersion profile from vehicle activity and its impact on the community in Simpang Lima Mandai, a heavy-traffic area and the location of the highest ambient NO₂ concentration in Makassar. Methods: A field survey and AERMOD Gaussian dispersion modeling were used in this quantitative study. Traffic volume, vehicle type, speed, and segment length were classified as primary data, while emission factors (EMEP/EEA 2019; MOVES) BMKG Makassar's meteorological data were classified as secondary data. A bottom-up emissions inventory was used to calculate NO₂ emission loads, and WHO (2021) and PP No. 22/2021 air quality standards were used to compare model results. Results: The model indicated that the average NO₂ concentrations over 1 h (348.8 µg/m³) and over 24 h (82.49 µg/m³) represented high exposure risk in the Simpang Lima Mandai area. The residents from the nearby settlements were found to be more vulnerable because of their long-term residence in the polluted area, with a weekly exposure of 4,452 µg/m³. Motor vehicles are a significant contributor to NO₂ pollution, according to the study. Conclusion:Motor vehicle NO₂ emissions at Simpang Lima Mandai are higher than WHO standards, and the highest exposure was recorded for neighboring residents at 4,452 µg/m³/week. We recommend evidence-based interventions such as enhanced traffic management, additional green buffers, and periodic NO₂ monitoring to protect these high-exposure communities.

Abstract

This community service program on the socialization of coal quality and environmental mitigation efforts was conducted to enhance green energy literacy and strengthen local capacity in addressing energy and environmental challenges. Indonesia remains heavily dependent on coal as its primary energy source, yet the low quality of domestic coal, characterized by high sulfur, ash, and moisture content, contributes significantly to carbon emissions, air pollution, and solid waste residues. The study employed a qualitative descriptive approach with participatory action research (PAR), actively involving the community in problem identification, planning, implementation, and reflection. The results revealed an increase in public knowledge regarding the relationship between coal quality and environmental impacts, alongside the emergence of collective awareness to propose relevant mitigation measures. Furthermore, the program emphasized the importance of adopting coal upgrading technology as a technical solution to reduce sulfur content and enhance calorific value, thereby improving combustion efficiency and reducing environmental burdens. The integration of scientific analysis, energy policy, and community participation positions this program as a strategic model of community service that supports the achievement of the Sustainable Development Goals (SDGs), particularly Goal 7 (Affordable and Clean Energy) and Goal 13 (Climate Action).
