Optimization of Groundwater Potential as a Sustainable Resource to Support the Socio-Economic Activities of the Community in Tantan Village, Sekernan Subdistrict, Muaro Jambi Regency

Abstract

Clean water is a fundamental need, yet its availability remains a serious challenge in many rural areas, including Tantan Village, Sekernan Subdistrict, Muaro Jambi Regency. The village is not connected to the PDAM network, leaving residents dependent on dug wells that often run dry and produce poor-quality water. This community service program aimed to identify groundwater depth potential using the Schlumberger geoelectrical configuration method. The activities were carried out in three stages: preparation (initial survey and coordination with partners), implementation (geoelectrical data collection and community discussions), and follow-up (result dissemination, mentoring, and groundwater potential mapping). The effectiveness of the socialization was assessed using N-gain analysis through pretest and posttest evaluations. Results showed that community understanding improved from low to medium and high categories, with an average N-gain score of 0.517 (moderate category). These findings indicate that field-based socialization is effective in enhancing community literacy on groundwater mapping. The program not only produced groundwater depth maps as a basis for productive bore well planning but also strengthened the village’s capacity to manage water resources sustainably in support of local socio-economic needs.
