Abstract

Kabupaten Ponorogo mempunyai wilayah batuan kapur, tepatnya di Gunung Beser. Gunung Beser ini menjadi kawasan pertambangan batu kapur. Daerah ini diproyeksikan menjadi sebuah museum Reog Ponorogo. Penggunaan dinamit dilakukan di daerah ini selama dilakukan eksploitasi batu kapur yang dikhawatirkan menyebabkan kondisi bawah permukaan terdapat rekahan. Demi keamanan Detail Engineering Design (DED) dan pembangunan, dibutuhkan informasi tentang kondisi bawah permukaan yang detil. Metode resistivitas 2D dengan konfigurasi dipole-dipole digunakan dalam penelitian ini. Lintasan pengukuran sebanyak 12 lintasan. Panjang tiap lintasan yaitu 235 meter dengan spasi tiap elektroda 5 meter. Data pengukuran kemudian diolah hingga didapatkan resistivitas semu dan hasilnya adalah penampang resistiviats 2D. Rentang nilai resistivitas yang diperoleh yaitu 9,10 Ωm hingga 512 Ωm. Diindikasikan adanya rekahan terhubung pada lokasi A pengukuran.

Ponorogo Regency has a limestone area, precisely on Mount Beser. Mount Beser is a limestone mining area. This area is projected to become a Reog Ponorogo museum. The use of dynamite is carried out in this area during the exploitation of limestone which is feared to cause fractures in the subsurface conditions. For the safety of Detail Engineering Design (DED) and construction, detailed information about subsurface conditions is required. The 2D resistivity method with dipole-dipole configuration is used in this study. The measurement trajectory is 12 tracks. The length of each track is 235 meters with a space of 5 meters for each electrode. The measurement data is then processed to obtain apparent resistivity and the result is a 2D resistivity cross section. The range of resistivity values obtained is 9.10 Ωm to 512 Ωm. Indicated the presence of a fracture connected at location A measurement.
