Abstract

Water pollution is a pressing global issue, particularly in regions heavily impacted by industrialization. This results in aquatic ecosystem degradation, biodiversity loss, and significant health risks from waterborne diseases and prolonged exposure to toxic pollutants. Industrial waste is a key contributor, highlighting the urgency of effective mitigation strategies. This study aimed to analyze research trends in industrial water pollution, identify knowledge gaps, and provide actionable insights for policymakers. A bibliometric analysis and literature review were conducted on 2,523 articles published between 2015 and 2024 using R software and the Biblioshiny interface. In addition, 30 highly cited articles were reviewed in-depth to explore dominant themes and advancements. The findings show a marked increase in research output, with China as the leading contributor. Key topics include the impact of industrial effluents, innovative water treatment technologies, and regulatory measures. However, significant gaps remain, particularly in interdisciplinary approaches and research on developing countries, such as Indonesia. This study recommends advancing scalable, cost-effective hybrid technologies, fostering interdisciplinary collaboration, and promoting public awareness initiatives. This study highlights the need to integrate technological, social, and policy dimensions to address industrial water pollution effectively, offering a pathway for sustainable solutions and future research directions.

Abstract

Global environmental challenges such as climate change, pollution, and ecosystem degradation require urgent responses, and education plays a strategic role in building environmental literacy. This study aimed to evaluate the readiness of higher education curricula in supporting sustainable learning in Environmental Chemistry courses and their alignment with the Sustainable Development Goals (SDGs). The research used a descriptive approach involving curriculum and lesson plan analysis, student surveys, and interviews with lecturers and program heads at a state university in Aceh Province, Indonesia. The findings show that while the curriculum includes relevant topics such as pollution and climate change, the integration of emerging issues and practical learning methods remains limited. Students demonstrated positive attitudes and awareness toward environmental sustainability, but their active involvement in practical actions was still low. Recommendations include the explicit integration of SDGs in course plans, diversification of teaching strategies through fieldwork and case studies, and fostering interdisciplinary collaboration. Overall, the study concludes that the curriculum provides a strong foundation but requires strategic improvements to enhance its relevance and impact. Aligning academic programs with global and local environmental challenges will enable higher education to prepare students as proactive agents of sustainable development.

Abstract

Research on chemistry education has consistently centered on students' conceptual and procedural knowledge. However, there is a clear need to prioritize how learners apply chemical thinking to address complex real-world problems. This gap highlights the need to understand how students and teachers connect molecular-level reasoning with broader social, ethical, and environmental contexts. A systematic review is the clear solution to address this issue. It will map trends, gaps, and strategies that foster the development of chemical thinking. This study provides a comprehensive overview of chemical thinking research in chemistry education through bibliometric and thematic analysis. A total of 59 scopus-indexed articles published between 2012 and 2025 were analyzed using the bibliometrix package in R and the biblioshiny interface. The analysis focused on publication trends, thematic evolution, collaboration networks, and instructional strategies. The results are clear: most studies target secondary and undergraduate learners, emphasizing causal reasoning, structure, property relationships, and representational competence. However, there are significant gaps in research concerning preservice teachers, assessment practices, and contextual approaches such as project-based and socio-scientific learning. Future studies must integrate reasoning, modeling, and sustainability-oriented frameworks. Effective strategies include inquiry-based, reflective, and socially relevant approaches. These approaches promote conceptual understanding and ethical reasoning. They offer valuable guidance for curriculum innovation and teacher education in chemistry

Abstract

Program merdeka belajar dianggap sebagai konsep revitalisasi dalam dunia pendidikan di Indonesia. Hasil analisis terhadap mitra guru SMA se-Aceh Utara ditemui permasalahan utama yaitu kurangnya minat dan keaktifan siswa dalam pembelajaran sehingga siswa dalam pembajaran cenderung pasif dan berdampak pada pencapaian kompetensi siswa. Permasalahan lainnya yaitu guru belum mengimplementasikan kurikulum merdeka dengan baik, dari tinjauan pelaksanaan proses belajar mengajar yang cenderung student-centered learning dan masih memberikan soal latihan atau tes kepada siswa sebagai tolok ukur keberhasilan pembelajaran. Pemberian materi mengenai kurikulum merdeka serta cara mengaplikasikannya dalam proses pembelajaran serta pelatihan dan pendampingan perencanaan Projek Penguatan Profil Pelajar Pancasila (P5) kepada guru dapat meningkatkan pemahaman guru terhadap implementasi kurikulum merdeka. Adapun target dari kegiatan ini diantaranya: 1) kemampuan guru dalam merancang projek selama proses pembelajaran meningkat, 2) minat dan keaktifan siswa dalam proses belajar mengajar tinggi, dan 3) jumlah bahan ajar yang menunjang P5 meningkat.
