Peran Limbah Ternak dalam Ekonomi Sirkular Pertanian Membangun Sistem Agroekologi yang Regeneratif

This study explores the role of livestock waste management in creating a regenerative agroecology system through the principles of circular economy, focusing specifically on the agricultural sector in West Sumatra, Indonesia. The research aims to evaluate the potential of livestock waste as an organic fertilizer, its contribution to reducing chemical fertilizer usage, and its impact on agricultural productivity. The methodology used is a Systematic Literature Review (SLR), analyzing recent studies (2018-2023) related to circular economy, regenerative agriculture, and livestock waste management. The results demonstrate that efficient management of livestock waste can significantly enhance soil fertility, reduce dependency on chemical fertilizers, and improve crop yields. Specifically, the conversion of 150,000 to 350,000 tons of livestock waste annually could lead to the production of 75,000 to 250,000 tons of organic fertilizer, reducing chemical fertilizer use by up to 75,000 tons per year and increasing productivity by 10% to 30%. These findings suggest that integrating circular economy principles into livestock waste management can contribute to sustainable agricultural practices in West Sumatra.
