Abstract

Tingkat penggunaan bahan bakar fosil yang tinggi memiliki dampak yang sangat berbahaya terhadap bumi. Oleh karena itu, penting untuk mengeksplorasi serta mengadopsi sumber energi alternatif. Biomassa dianggap sebagai sumber bahan bakar yang menjanjikan karena ketersediaannya yang melimpah di alam. Desa Telukambulu yang memiliki luas lahan sawah 84% dari total luas wilayahnya sehingga tidak hanya menghasilkan produk hasil pertanian yang bisa diperjualbelikan, tetapi juga menghasilkan limbah pertanian yang cukup besar khususnya limbah sekam padi. Oleh karena itu, penting untuk dilakukan pelatihan dalam memanfaatkan limbah sekam padi menjadi bahan bakar alternatif berupa briket. Kegiatan dirancang melalui dua sesi pelatihan, yakni pelatihan terstruktur dan pelatihan partisipatif. Pelatihan terstruktur mencakup sosialisasi mengenai briket dan pemaparan materi mengenai analisis ekonomi produk briket dengan metode ceramah, sementara pelatihan partisipatif melibatkan demonstrasi langsung pembuatan briket. Hasil kegiatan pelatihan kemudian dievaluasi, hasilnya lebih dari 80% peserta sangat setuju bahwa pelatihan yang dilakukan memberi pengetahuan, memberi gambaran teknis pembuatan briket dari limbah sekam padi, serta memberikan pengetahuan terkait analisis nilai ekonomi dari produk briket ketika dikomersilkan. Selain itu, sekitar 75% peserta terdorong untuk melakukan pengolahan limbah sekam padi menjadi briket untuk dikomersilkan. Sehingga perlu ada upaya tindak lanjut secara berkala untuk memastikan pemanfaatan limbah tetap optimal. Secara keseluruhan, pelatihan ini tidak hanya memberikan manfaat langsung kepada peserta, tetapi juga membuka potensi baru bagi masyarakat desa dalam memanfaatkan sumber daya lokal secara berkelanjutan, sekaligus mengurangi dampak negatif limbah terhadap lingkungan.

Abstract

Waste management systems like TPS3R are critical for reducing, utilizing, and managing trash at its source. However, the TPS3R presence in Telukjambe Village has not been perceived as effective in conducting waste management as required. One major issue with the TPS3R's insufficient waste management is the unsegregated waste entering the facility, which is caused by the nearby locals' lack of understanding about domestic waste sorting. Therefore, it is imperative to implement initiatives aimed at enhancing knowledge and concern about waste separation among the people surrounding the TPS3R in Telukjambe Village. We implement educational campaigns on waste separation through door-to-door outreach, where representatives visit residents' homes to provide technical information on home-based waste sorting using diverse educational media. Furthermore, to improve understanding of waste sorting and TPS3R management, we conducted socialization by inviting speakers to deliver the information in an engaging and participatory manner. The evaluation results indicate that around 82.4% of respondents, specifically those living there, answered the waste sorting questions accurately. The locals possess a solid comprehension of garbage sorting, providing a robust platform for increased participation in household waste segregation. Furthermore, the local government's role in establishing legislation for household trash segregation and TPS3R management can guarantee the sustainability of current initiatives, ensuring their continued implementation.

Abstract

Diazinon is a commonly used organophosphate insecticide in agriculture, but its persistence in water and soil presents significant health and environmental concerns. This study investigates the photocatalytic removal of diazinon from aqueous solutions using zinc oxide (ZnO) nanoparticles activated by visible light irradiation. ZnO was chosen due to its excellent photocatalytic properties, including a direct band gap (~3.1 eV), strong oxidative capability, chemical stability, and non-toxic nature, making it a superior candidate for visible-light-driven environmental remediation. Photocatalytic degradation under sunlight was also assessed for comparison. Key operational parameters, such as photocatalyst dosage, solution pH, initial diazinon concentration, and irradiation time, were systematically optimized. The highest degradation efficiency degradation was achieved with 20 mg of ZnO, neutral pH, 30 mg/L an initial concentration, and 60 minutes of irradiation. Kinetic analysis revealed that the process followed zero-order reaction kinetics (k = 1.118; R2 = 0.9962). Notably, visible light irradiation was more effective than sunlight in degrading diazinon. These findings provide important details about the potential of ZnO nanoparticles as an efficient, low-cost, and environmentally friendly photocatalyst for remediating pesticide-contaminated water under sustainable energy conditions.

Abstract

Surface water is the primary source of water for communities but is highly susceptible to contamination that can pose health risks. Telukambulu, a village in Karawang, West Java, faces challenges in household clean water quality. This community service activity aims to evaluate household water quality through the assessment of physical water parameters and screening using water test strips to measure chemical parameters. Analysis reveals that household water is not entirely suitable for daily needs such as drinking and cooking, with chemical parameters like pH, alkalinity, and chlorine levels being inconsistent. Community education was conducted to enhance understanding of the importance of water management, coupled with the application of simple filtration technology for water purification. This solution was designed to be easily adopted and sustainable. The program successfully raised community awareness about the importance of clean water quality and provided practical guidelines for improving household water quality. Through this approach, it is expected that the community can manage water more healthily and support better living standards.
