Agricultural on the Utilization of Beram-Based Local Microorganisms for Water Spinach Cultivation at Sungai Utik Indigenous Community. Supervised by WIDYA HASIAN SITUMEANG and MOCHAMAD HASJIM BINTORO DJOEFRIE. Community-based agricultural extension based on local wisdom is an effort to improve the knowledge and skills of Indigenous communities in crop cultivation. This study aimed to improve the understanding of the Sungai Utik Indigenous Community regarding the production and utilization of local microorganisms (MOL) made from beram, as well as to analyze the effects of its application on the growth of water spinach. The methods included agricultural extension activities, pre-tests and post-tests to measure improvements in knowledge, and field experiments to evaluate the effects of MOL application on plant growth. The data were analyzed using the Wilcoxon test and ANOVA. The results showed that beram, which holds cultural value, can function as a source of local microorganisms (MOL), in accordance with the traditional practice of “feeding the soil” practiced by the Sungai Utik Indigenous Community. There was a significant increase in the community’s knowledge following the extension activities. The community also expressed positive perceptions of the use of beram-based MOL in water spinach cultivation. Furthermore, the application of beram-based MOL had a significant effect on plant growth, as indicated by increases in plant height, stem diameter, and number of leaves. This study demonstrates that community assistance and the utilization of MOL have the potential to serve as sustainable innovations in supporting environmentally friendly agriculture based on Indigenous knowledge and practices. 2026-01-01T00:00:00Z http://repository.ipb.ac.id/handle/123456789/179571 Pengaruh Variasi Konsentrasi Organik Cair Limbah Tempe dan Bonggol Pisang terhadap Pertumbuhan Vegetatif Tanaman Cabai Merah (Capsicum annuum L.) fitriah, Siti Cabai merah merupakan komoditas hortikultura penting di Indonesia, namun produktivitasnya masih rendah akibat penurunan kesuburan tanah dan ketergantungan terhadap pupuk anorganik.
