Abstract

This research investigates the environmental comfort conditions—thermal, visual, and acoustic—in six functional spaces at SD Negeri 8 Ragunan, South Jakarta, a public elementary school recognized for its sustainability-focused infrastructure. The study emphasizes the relevance of indoor environmental quality in shaping students’ cognitive performance, well-being, and overall learning experience. A mixed-methods design was employed, combining quantitative field measurements with qualitative spatial analysis. Data collection included temperature (28.5°C–32.1°C), relative humidity (65%–78%), light intensity (263–712 lux), and sound levels (41.3–64.5 dBA), measured in four classrooms, one hall, and one teachers’ room. Qualitative data involved architectural observations on ventilation, daylight access, and environmental policy signage. Results were benchmarked against Indonesian national standards (SNI 6390:2011, SNI 6197:2020, SNI 6386:2000) and international guidelines (ASHRAE 55-2017, GBCI). Findings indicate that temperature and illumination were within permissible thresholds, and visual connectivity reached 94.83%, exceeding GBCI’s 75% standard. However, humidity levels consistently surpassed the 60% threshold, and noise levels occasionally exceeded recommended limits, particularly in rooms near traffic exposure. Moreover, anti-smoking signage was insufficient and inconsistently placed. These results highlight the need for integrated environmental management strategies in school buildings. The study contributes to the discourse on sustainable educational facilities and supports the implementation of SDG 4 (Quality Education) and SDG 11 (Sustainable Cities and Communities), particularly in rapidly urbanizing tropical regions.

Abstract

This study investigates mud management in the West Banko area at PT Bukit Asam, focusing on predicting erosion rates, estimating mud volumes, and evaluating sediment pond (KPL) capacity. The methodology integrates field data collection (rainfall, runoff, and soil properties), the Universal Soil Loss Equation (USLE) approach—considering rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), and cover-management (C)—and sediment delivery ratio (SDR) analysis to estimate sediment yield. Results indicate that the predicted annual erosion rate reached 10,818,825.04 m³/year in Pit SJS, 3,190,396.61 m³/year in Pit E, and 1,642,899.98 m³/year in Pit 3 East. After applying SDR values, the corresponding estimated mud (sediment yield) volumes were 3,129,918.88 m³/year (Pit SJS), 971,015.11 m³/year (Pit E), and 500,266.05 m³/year (Pit 3 East). These findings highlight the significant sediment load generated by mining activities, requiring large-capacity sediment ponds to maintain sump functionality and prevent pump inefficiency. The scientific contribution of this study lies in providing a comprehensive quantitative framework for predicting erosion and sediment yield in dynamic open-pit mining environments. By combining hydrological, soil, and slope factors into an integrated mud management system, the research enhances environmental engineering practices by supporting optimized sump design, sediment pond planning, and sustainable water management strategies. Overall, effective mud management not only ensures operational efficiency and slope stability but also minimizes environmental risks, aligning coal mining operations with good mining practices and regulatory compliance.
