Abstract

Sistem ventilasi pada kandang sapi memiliki peran penting dalam menjaga kesehatan ternak dan efisiensi produksi, terutama dalam mengendalikan penyebaran penyakit. Penelitian ini mengevaluasi kinerja sistem ventilasi kandang sapi terhadap distribusi aliran udara dan pergerakan partikel pembawa virus Foot-and-Mouth Disease (FMD) dengan menggunakan pendekatan simulasi CFD. Dua skenario dibandingkan, yaitu ventilasi alami dan ventilasi mekanik dengan penambahan supply fan. Analisis dilakukan pada kontur kecepatan, pola streamline, fraksi partikel suspended dan escaped, serta visualisasi particle residence time secara transien pada 210 detik. Hasil menunjukkan bahwa pada natural ventilation pola aliran udara yang terbentuk tidak merata dengan zona resirkulasi yang signifikan, jumlah partikel suspended tinggi, dan waktu tinggal partikel lebih lama. At 210 seconds, the fraction of suspended particles in the natural and mechanical ventilation systems was 86.1% and 12.1%, respectively. The number of escaped particles in the natural and mechanical ventilation systems was 13.9% and 87.9%, respectively. Temuan ini mengindikasikan bahwa ventilasi mekanik lebih efektif dalam meningkatkan pencampuran udara, mempercepat pembuangan partikel tercemar, serta menekan risiko penyebaran virus PMK secara airborne di dalam kandang sapi.

Abstract

Urban waste generation continues to rise in line with increased consumption patterns, particularly in rapidly developing cities. This study analyzes the effectiveness of community-based waste banks in reducing municipal waste volume, lowering methane emissions, and strengthening urban climate resilience. Waste banks play a pivotal role in diverting recyclable and organic materials from landfills through structured sorting systems, economic incentives, and integrated organic processing such as composting and maggot cultivation. These mechanisms significantly reduce anaerobic decomposition, which is the primary source of methane emissions in landfills. Community participation, institutional capacity, technological support, and government collaboration emerge as key factors that determine the overall performance of waste bank programs. The development of circular economy practices within waste bank operations contributes to environmental quality improvement while simultaneously generating economic benefits for local communities. The findings highlight that waste banks are not only tools for waste reduction but also essential components of urban climate mitigation strategies. Their ability to integrate social, ecological, and economic functions positions them as effective, low-cost solutions for modern urban environmental management.
