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).

Abstract

Road-cut slopes in tropical carbonate terrain are affected by the interaction of geometry, weathering, material strength, and seasonal water input. This study evaluated two weathered limestone road-cut slopes along the Maros-Bone corridor, South Sulawesi, Indonesia, using engineering-geological observations, laboratory properties, the Simplified Janbu method, and independent regional rainfall data. Site 1 in Cenrana is approximately 15 m high with a 43° inclination, whereas Site 2 in Mallawa is approximately 18 m high with a 55° inclination. Representative parameters were c = 12 kPa, φ = 21°, and γ = 12.7 kN/m³ for Site 1 and c = 14 kPa, φ = 28°, and γ = 13 kN/m³ for Site 2. The calculated factors of safety were 1.043 and 1.002, indicating very limited stability margins. Regional climate records for 2023 showed 3,336 mm of annual rainfall over 132 rainy days, with 94.1% occurring from November to April and monthly peaks of 1,091 mm in February and 803 mm in January. The rainfall data were used as hydroclimatic context rather than hydraulic model input. The findings indicate that weathering and seasonal wetness may aggravate Site 1, while steep geometry is especially critical at Site
