Abstract

Salah satu metode Geofisika yang sering digunakan untuk menginvestigasi lapisan tanah bawah permukaan adalah metode geolistrik Tahanan jenis. Penelitian ini bertujuan untuk memodelkan secara 2D lapisan tanah Lahan pembangunan Rumah Sakit Jantung Provinsi Sulawesi Tenggara berdasarkan nilai tahanan jenis menggunakan konfigurasi Wenner.pengukuran dilakukan dengan menginjeksikan arus di bawah permukaan bumi kemudian di ukur nilai beda potensial listrik dan arus lstrik. Pengolahan data menggunakan perangkat lunak Res2Dinv. Berdasarkan informasi Geologi, maka diperoleh jenis batuan dan nilai resistivitasnya sebagai berikut : Lempung (0,1 – 30 Ωm), batu pasir (30 – 100 Ωm) dan kerikil (100-160 Ωm).Kata kunci: Pemodelan, konfigurasi Wenner, Res2Dinv

Abstract

Research has been carried out in the non-volcanic geothermal area of Lainea, South Konawe Regency on hydrogeophysics using the geoelectrical method of resistivity. The purpose of this study was to determine the subsurface lithology and hydrological potential in the research area. Geoelectrical resistivity measurements were carried out on 5 measurement lines using the Schlumberger configuration and data processing using the PROGRESS application. The results of the alignment between the subsurface model, resistivity table and geological conditions, the lithology of the research area consists of overburden with resistivity values between 18.09 ohmmeter - 241.2 ohmmeter, sandstone with resistivity value 19.81 Ohmmeter - 344.6 Ohmmeter and clay with a resistivity value of 2.88 Ohmmeter – 12.78 Ohmmeter and the potential of the aquifer is in sandstone lithology with different depths and thicknesses between measurement paths.Key words: Geothermal, Lainea, Geoelectrical,lithology,aquifer
