Abstract

Kawasan Pacitan memiliki kondisi geologi yang khas, karena sebagian besar kawasan pacitan terdiri dari batuan karbonat yang telah mengalami proses karstifikasi. Proses karstifikasi dapat menghasilkanpori, rongga dan goa pada kedalaman tertentu dan ditambah sifat fisik batuan karbonat yang impermeable sehingga membentuk sistem sungai bawah permukaan.Penelitian ini bertujuan untuk identifikasi karakteristik bawah permukaan kawasan karst desa Sekar, Pacitan menggunakan metode geolistrik 1D Konfigurasi Schlumberger.Hasil pengolahan data memperlihatkanbahwa batuan penyusun kawasan karst Desa Sekar, Pacitan adalah batugamping klastik dengan nilai resisitivitas semu 0-50 Ωm dan batugamping terumbu dengan nilai resistivas semu .100-500 Ωm ========== Pacitan region hadanunique geological condition, because most of the pacitan region consists of carbonate rock that has undergone aprocess of karstification. The process of karstification can produce pores, cavities and caves at certain depths and added the physical properties of impermeable carbonate rocks to form asubsurface river system. This study aims to identify the characteristics of subsurface karst area of Sekar Village, Pacitan using geoelectrical 1D method with schlumberger configuration. Results of data processing showed the form ation rocks in the karst area of Sekar village arranged by clastic limestone with the resistivity value 0-50 Ωm and coral limestone that had resistivity value around 100-500 Ωm.
