Abstract

The Enim River in Muara Enim Regency, South Sumatra, remains vital for various community activities. However, as an open water source, it is vulnerable to waste inputs from surrounding human activities, which impact the river's overall condition. This research aims to assess the water and sediment quality of the Enim River by analyzing key parameters such as pH, TSS, Fe, Mn, and temperature. Additionally, it seeks to explore the correlation between Fe and Mn content in both water and sediment and evaluate the quality status of these elements. The methodology involves descriptive analysis, where the measured values are compared against established quality standards. Correlation analysis is used to examine the relationship between Fe and Mn concentrations in water and sediment. Furthermore, the Pollution Index (PI) and Geo-accumulation Index (Igeo) methods are applied to determine the quality status of water and sediment. The findings indicate that the water quality of the Enim River exceeds acceptable standards for TSS, Iron (Fe), and Manganese (Mn). Regarding sediment quality, the Iron (Fe) levels surpass the Severe Effect Level (Level 3), while Manganese (Mn) remains below the Lowest Effect Level (Level 2). The correlation analysis reveals a strong negative correlation (-1) between Fe and Mn in water and sediment, suggesting a tightly linked inverse relationship. Overall, the Enim River's water quality is classified as Mildly to Moderately Polluted. The sediment quality, however, varies. It is categorized as Extraordinarily to Extremely Severely Polluted for Iron (Fe) and Not Polluted for Manganese (Mn).

Abstract

Environmental education plays a critical role in shaping awareness, sustainable behavior, and civic responsibility. Despite the global growth of environmental education research, comparative analyses between countries with different socio-political and academic contexts remain limited. This study aims to examine the research landscape and thematic evolution of environmental education in Indonesia and the USA. A systematic bibliometric and thematic analysis was conducted on WoS publications from 1975–2025. The study integrates PRISMA-based systematic screening with bibliometric mapping using VOSviewer, enabling transparent article selection while revealing structural relationships among keywords, institutions, and research themes. A total of 812 articles were included after screening and eligibility assessment. The results reveal clear contrasts in research focus and collaboration structures. In the USA, dominant themes include pro-environmental behavior, science education, and urban green spaces, supported by dense institutional collaboration networks led by the University of Florida, Stanford, and Cornell. In contrast, Indonesian environmental education research emphasizes health, sanitation, education, and slum communities, with relatively limited inter-institutional collaboration. Keyword co-occurrence analysis indicates that while global clusters center on “environmental education” and “students,” Indonesian studies integrate context-specific topics such as “COVID-19,” “slums,” and “coastal communities.” This study contributes to environmental education knowledge mapping by providing a systematic cross-national bibliometric comparison that clarifies thematic priorities, collaboration patterns, and emerging research directions. The findings also support SDG-aligned research and policy development, particularly SDG 4.7 (education for sustainable development) and SDG 13 (climate action), by identifying opportunities to strengthen international collaboration and diversify thematic research agendas in environmental education.
