Abstract

Penelitian ini bertujuan untuk mengidentifikasi pola sebaran dan kedalaman lapisan batu pasir di area tambang batu pasir Pasuruan dengan menggunakan metode geolistrik konfigurasi Schlumberger. Metode ini dipilih karena mampu memberikan gambaran resistivitas bawah permukaan yang berhubungan dengan jenis batuan. Akuisisi data dilakukan pada lima lintasan sepanjang 100 meter dengan spasi antar lintasan 3 meter. Data resistivitas semu diperoleh melalui pengukuran lapangan dan kemudian diolah menggunakan perangkat lunak IPI2Win dan Progress V 3.0 untuk mendapatkan penampang 1D dan 2D bawah permukaan. Hasil interpretasi menunjukkan bahwa lapisan batu pasir memiliki nilai resistivitas yang bervariasi antara 8 hingga 4000 Ωm dan tersebar secara dominan di hampir semua lintasan, dengan kedalaman mulai dari 0 hingga 38 meter. Selain batu pasir, batuan lain seperti andesit, alluvium, clay, slate, dan kuarsit juga teridentifikasi. Penelitian ini memberikan informasi untuk pengelolaan sumber daya tambang secara berkelanjutan.

This study aims to identify the distribution patterns and depth of sandstone layers in the Pasuruan sandstone mining area using the Schlumberger configuration geophysical method. This method was chosen because it can provide a subsurface resistivity profile related to rock types. Data acquisition was conducted on five transects, each 100 meters long, with a spacing of 3 meters between transects. Pseudo-resistivity data were obtained through field measurements and then processed using the software IPI2Win and Progress V 3.0 to obtain 1D and 2D subsurface cross-sections. The interpretation results show that the sandstone layer has resistivity values ranging from 8 to 4000 Ωm and is predominantly distributed across nearly all profiles, with depths ranging from 0 to 38 meters. In addition to sandstone, other rock types such as andesite, alluvium, clay, slate, and quartzite were also identified. This study provides information for the sustainable management of mining resources.
