Abstract
Penelitian menggunakan metode geofisika resistivitas dan polarisasi
terimbas kawasan waktu (time domain) dengan maksud mengidentifikasi dan
menginterpretasi litologi dan keberadaan mineral grafit berdasarkan respon nilai
Resistivity dan Chargeability. Penelitian berlokasi di lapangan Tamboli,
Kabupaten Kolaka, Sulawesi Tenggara. Pengambilan data lapangan menggunakan
konfigurasi elektroda dipole – dipole dengan panjang lintasan pengukuran 200 m
yang berjumlah 15 lintasan. Perangkat lunak yang digunakan adalah Ms. Excel,
Res2Dinv, Rockwork, Surfer, dan Map Info 3D Discover.
Hasil penelitian dan interpretasi terpadu dari beberapa lintasan, berdasar
data anomali resistivitas daerah telitian tersusun oleh batuan metamorf yang
terdiri dari batulempung dicirikan dengan nilai resistivitas >10 Ohm.m, batupasir
dicirikan dengan nilai resistivitas 10-150 Ohm.m, batuan metasedimen dicirikan
dengan nilai resistivitas 150-300 Ohm.m, Batuan Filit dicirikan dengan nilai
resistivitas 300-500 Ohm.m, batuan sekis dicirikan dengan nilai resistivitas 500-
1000 Ohm.m, sekis kompak dicirikan dengan nilai resistivitas 1000-5000 Ohm.m,
dan batuan Gneiss dicirikan dengan nilai resistivitas >5000 Ohm.m. Berdasarkan
data anomali Chargeability penyebaran mineral grafit mengarah dari arah selatan
ke arah utara yang ditandai dengan semakin banyaknya deposit mineral grafit
yang semakin meningkat, daerah potensi mineralisasi ditandai dengan nilai
Chargeability 100 - 400 m.sec. Dari pengolahan data sera interpretasi bawah
permukaan maka disimpulkan bahwa daerah penelitian memiliki potensi adanya
keberadaan mineral grafit yang sedikit. Mineral Grafit dijumpai berasosiasi
dengan batuan metasedimen, filit, serta batuan sekis.
Kata Kunci : Mineral Grafit, Metode Geolistrik, Polarisasi Terimbas, Time

The Research used geophysical resistivity and induced polarization time
domain with the purpose of indicating and interpretation the mineralized zones of
graphite based on the response value of resistivity and Chargeability. The
Research is located on the Tamboli field, Kolaka, Southeast Sulawesi. Collection
of field data used an electrode configuration dipole - dipole the measurement path
length of 200 m from 15 tracks. The software used is Ms. Excel, RES2DINV,
rockwork, Surfer, and 3D Map Info Discover.
Results of the research and integrated interpretation of several trajectories
based on data from the study area resistivity anomalies metamorphic rock
composed of claystone is characterized by resistivity values> 10 Ohm.m,
sandstone is characterized by resistivity values 10-150 Ohm.m, metasedimen rock
characterized by resistivity values 150-300 Ohm.m, Rock filit characterized by
resistivity values 300-500 Ohm.m, schist rocks are characterized by resistivity
values Ohm.m 500-1000, compact schist characterized by resistivity values
Ohm.m 1000-5000, and rock Gneiss is characterized by resistivity values> 5000
Ohm.m. Based on the Chargeability anomaly data the spread of mineral graphite
leads from the south to the north which is marked by the increasing number of
graphite mineral deposits increases, the potential areas of mineralization
characterized by Chargeability values 100-400 m.sec. In this research the
conclution is the study area has the potential for the presence of mineral graphite
slightly. Mineral Graphite is found associated with rock metasedimen, filit, and
schist rocks.
Keywords: Mineral Graphite, Geolistrik method, Induced Polarization, Time
