Abstract

Desa Jabung merupakan suatu desa yang berada di Kecamatan Jabung, Kabupaten Malang. Kondisi air tanah di desa ini beragam, ada wilayah dengan potensi air tanah yang bagus seperti Dusun Krajan, namun beberapa dusun lain seperti Umpak, Boro Jabung, Mindi, dan Gunungjati mempunyai potensi air tanah yang kurang baik dan tergolong daerah yang mengalami kekeringan. Kegiatan pengabdian kepada masyarakat dari dosen Departemen Fisika Universitas Brawijaya dilakukan di Desa Jabung pada tanggal 11 September 2020 kepada perangkat desa Jabung. Sosialisasi dilakukan secara semi-daring (hybrid) dengan perangkat desa Jabung dan satu orang dosen pelaksana berada di Kantor Desa Jabung, serta dosen pelaksana yang lain mengikuti sosialisasi ini lewat zoom. Materi sosialisasi yang diberikan berupa pengetahuan mengenai Air Bawah Tanah (ABT) dan hasil pemetaan potensi ABT di Desa Jabung. Dari hasil evaluasi kegiatan sosialisasi ini, diketahui bahwa materi sosialisasi sangat diperlukan oleh perangkat Desa Jabung untuk mengatasi kekeringan di Desa Jabung, serta harapan untuk melakukan kegiatan yang serupa di masa yang akan datang.

Abstract

Jabung Village, located in Jabung District, Malang Regency, has various groundwater potentials. The study using the Vertical Electrical Sounding (VES) geoelectric method was carried out in several hamlets in Jabung Village with water shortages to map the groundwater potential in these hamlets. VES measurements were carried out in Boro Lor Hamlet, Gunung Kunci Hamlet, Umpak Hamlet, and Mindi Hamlet, with 1 reference point measured next to a drilled well belonging to the Regional Government. The results of VES analysis in 4 hamlets show that the aquifer layer is a sandstone with a resistivity of 25.8-41.7 m. The thickness of the aquifer varies from 4.6 meters to 30.1 meters. The depth of the aquifer also varies from a depth of 40.6 meters to a depth of 68.6 meters.

Abstract

Geothermal energy is one of the natural resources found in Pacitan Regency, alongside mining and geotourism. Geothermal manifestations in Pacitan Regency take the form of hot springs located at two points: Tinatar in the Punung District and Karangrejo in the Arjosari District. This research primarily focuses on magnetic measurement methods at the Karangrejo hot spring manifestation to provide information about its subsurface geological conditions. Data acquisition was conducted using 2 Proton Precision Magnetometers (PPM) of the Geotron G-5 brand as both base and rover instruments. The acquired data was processed with diurnal correction, IGRF correction, separation of residual-regional anomalies, and Reduce to Pole (RTP) transformation. The research results show magnetic anomaly variations in the study area ranging from -220 nT to 200 nT. Some geological structures that could potentially be associated with the Karangrejo hot spring manifestation are north-south trending faults and northeast-southwest trending faults, while the lithology of the study area is dominated by kaolin alteration and andesite rocks. It is estimated that the Karangrejo geothermal system is a fault-hosted geothermal system resulting from fault activity.
