<![CDATA[Karst pada umumnya tersusun dari batuan gamping, biasanya meloloskan air hujan melalui celah-celah batuan tersebut. Hal ini yang mengakibatkan kekurangan air pada saat musim kemarau tiba yang mengakibatkan hilangnya air permukaan. Kami telah melakukan penelitian untuk mengidentifikasi akuifer di sekitar kawasanKarst Gombong Selatan, tepatnya berada di kecamatan Buayan, yang meliputi desa Nogoraji, Jogomulyo, dan Jatiroto, dengan menggunakan metode geolistrik menggunakan konfigurasi schulmberger. Data yang diperoleh kemudian diolah dengan software IPI2win, kemudian dibuat pemodelan 2D dengan software RockWorks15. Hasil penelitian didapatkan akuifer dangkal dalam kedalam 7,57-23,8 m batuan berupa pasir dan untuk akuifer dalam pada 144-242 m batuan berupa breksi ini berada di T4 (Jogomulyo), akuifer dalam pada 131-223 mbatuan pasir gampingan pada T5 (Nogoraji). Sedangkan pada T1 (Jatiroto), T2 (Jogomulyo), T3 (Jogomulyo) tidak ditemukan keberadaan akuifer karena batuan yang teridentifikasi berupa napal, tufa, napal tufaan, dan lempung karena batuan tersebut termasuk impermeable.ABSTRACTKarst is usually composed from limestone, which often leaks rain water through holes in the limestone. As the result, drought often happens during dry season. We conducted a study to identify aquifer using geo-electric method with Schlumberger configuration, around the Southern Gombong Karst Region in Buayan district, precisely in Nogoraji, Jogomulyo, and Jatiroto village.The obtained data were processed using IPI2win software, and then we made 2D model using RockWorks 15. From this model, we found that a shallow aquifer as sandstone is located at the depth of 7,57-23,8 m, and an aquifer as breccias at the depth of 144-242 m. Both aquifer are located in T4 (Jogomulyo). Additionally, we also found an aquifer as limestone at the depth of 131-223 m, which is located in T5 (Nogoraji). However, we did not found any aquifer in T1 (Jatiroto), T2 (Jogomulyo), and T3 (Jogomulyo), because we only identified marl, tuff, tuffaceous marl and clay layer, which are impermeable.]]>
