Pengelolaan DAS Mikro: Best Practice Penanganan Potensi Konflik Akibat Semburan Gas di Lahan Pertanian Desa Nglobo, Kabupaten Blora, Jawa Tengah

Abstract

Gas emissions occurring in the agricultural land of Nglobo Village, Blora Regency, Indonesia, have led to land contamination, resulting in worsened of watershed health over time. The evidence is apparent in the water and soil quality exceeding water quality standard. Consequently, conflicts have arisen in the community due to failed harvests of rice and corn, impacting crops failed. The aim of this research is to restore the health of the contaminated watershed, addressing both agricultural land and water quality. The methodology in this research involves a micro watershed management approach, which includes discussion activities with the community and other parties, remediation efforts, field schools and monitoring and evaluation. The study findings suggest that the addition of organic fertilizers to restore soil fertility, particularly enhancing soil organic carbon, is crucial. This is achieved by applying 29.58 tons/ha to 30.14 tons/ha of fertilizer on the affected land. Post-remediation water quality shows values below the threshold, indicating the health of the Nglobo river basin. The results of the planting test evaluation showed that rice and corn were in good condition, as evidenced by the absence of crop failure, and the fertility of agricultural land could be restored.  Micro watershed management approach, of measurable, with real action together with the affected communities and related parties, can resolve social conflicts that occur due to pollution of community agricultural land.
