Abstract
INDONESIA:
Penelitian ini bertujuan untuk mengetahui sebaran batubara dan struktur bawah permukaan. Survei yang dilakukan dalam penelitian ini menggunakan survei resistivitas geolistrik. Resistivitas geolistrik merupakan salah satu metode dalam geofisika yang memanfaatkan sifat aliran listrik di dalam bumi. Survei dilakukan dengan cara mengalirkan arus listrik DC yang mempunyai arus tegangan tinggi ke dalam tanah tanpa merusak material-material dalam tanah. Hasil survei diinterpretasikan dengan menggunakan pemodelan 2D dan 3D pada Res2dinv. Pada pemodelan dua dimensi, lapisan tanah yang mengandung batubara ditunjukkan skema warna merah hingga ungu tua dengan nilai resistivitas 200-610 ohm meter. Zona yang terdeteksi keberadaan sebaran batubara berada pada lintasan 2 dengan titik koordinat 08°16.157'-08°16.190' LS dan 111°45.351'-111°45.344' BT sepanjang 20 meter dari titik awal, serta lintasan 3 yang berada pada koordinat 08°16.160'-08°16.185 LS dan 111°45.361'-111°45.358' BT sepanjang 20 meter dari titik awal.
ENGLISH:
This study aims to find out the distribution of coal and subsurface structure. Surveys that have been done in this study was using geoelectrical resistivity survey. Geoelectrical resistivity is one of the methods in geophysics that utilizes the nature of electricity in the earth. Survey was done by flowing DC current that has high voltage current into the ground without damaging materials in the soil. Survey results were interpreted by using 2D and 3D modeling on Res2dinv. In two dimensional modeling, a coal-filled soil layer shown as red to purple color scheme with a resistivity value of 200-610 ohm meters. The detected zone of coal distribution is located on track 2 with the coordinate point 08 ° 16.157'-08 ° 16.190 'LS and 111 ° 45.351'-111 ° 45.344' BT with leght of 20 meters from the starting point, and track 3 located at coordinates 08 ° 16.160'-08 ° 16.185 LS and 111 ° 45.361'-111 ° 45.358 'BT with length of 20 meters from the starting point.
