Abstract

Permasalahan sampah masih menjadi isu global dan nasional akibat meningkatnya timbulan sampah serta rendahnya kesadaran pengelolaan di masyarakat. Di Desa Cirahayu, tumpukan sampah rumah tangga yang dibakar terbuka menimbulkan polusi udara dan gangguan kesehatan. Kegiatan ini bertujuan memberikan solusi praktis melalui penerapan alat pembakaran sampah berbasis drum incinerator modifikasi dua lapis yang ramah lingkungan dan mudah diterapkan. Metode yang digunakan adalah pendekatan partisipatif berbasis Community-Based Action Research (CBAR) dengan lima tahapan: persiapan, perancangan alat, sosialisasi, implementasi, serta evaluasi. Alat dibuat dari drum bekas berkapasitas 200 liter dengan sistem ventilasi oksigen dan lapisan termal untuk meningkatkan efisiensi pembakaran. Hasil uji lapangan menunjukkan bahwa alat mampu mengurangi volume sampah hingga 65–70% dalam waktu sekitar 40 menit per siklus, dengan residu abu halus dan asap tipis. Kegiatan ini juga meningkatkan kesadaran masyarakat terhadap pengelolaan sampah berkelanjutan. Penerapan teknologi tepat guna ini terbukti efektif, murah, dan dapat direplikasi di tingkat rumah tangga atau komunitas desa untuk mendukung lingkungan bersih dan sehat

Abstract

Bank profitability is essential for maintaining financial-sector stability and supporting sustainable economic intermediation. This study examines the effects of credit risk and capital adequacy on profitability and investigates the mediating role of net interest margin in conventional commercial banks listed on the Indonesia Stock Exchange during 2022–2024. A quantitative causal-associative design was employed using secondary financial data. The population consisted of 42 banks, from which 34 banks were selected through purposive sampling, producing 102 observations. Data were analyzed using path analysis with LISREL 10.20. The results show that Non-Performing Loans (NPL) significantly affect Return on Assets (ROA), whereas the Capital Adequacy Ratio (CAR) has no significant direct effect on ROA. NPL does not significantly affect Net Interest Margin (NIM), while CAR has a significant effect on NIM. Furthermore, NIM significantly and positively affects ROA. The mediation analysis indicates that NIM does not mediate the relationship between NPL and ROA but significantly mediates the relationship between CAR and ROA. These findings demonstrate that profitability is primarily associated with credit quality and intermediation performance, while capital adequacy contributes indirectly through its ability to strengthen net interest income generation and improve banking profitability. These results provide practical implications for effective bank financial management.
