Penelitian mengenai analisis data geolistrik metode Induced Polarization
(IP) pada daerah “FK”. Secara stratigrafi, daerah penelitian tersusun atas Endapan
Aluvium, Basal Bunga, Granit sukadana, dan Gunungapi Kerabai. Kejadian
tektonik yang ada di Kalimantan menyebabkan melimpahnya sumber daya alam
di daerah penelitian diantaranya yaitu mineral logam. Penelitian ini bertujuan
untuk megetahui sebaran dan besarnya sumberdaya mineral logam didaerah “FK”.
Pada penelitian ini menggunakan 8 lintasan dengan jarak spasi antar
elektroda 20 meter. Arah orientasi lintasan pengukuran yaitu utara-selatan dengan
panjang lintasan sejauh 580 meter. Tahap pengolahan data yakni dengan
menggunakan software Res2Dinv sehingga diperoleh model penampang 2D
resistivitas dan chargeabilitas, kemudian dilakukan pemodelan 3D untuk
mengetahui besarnya sumberdaya mineral logam didaerah penelitian. Dari model
3D kemudian dilakukan slicing perkedalaman untuk mengetahui keberadaan dari
mineral logam tersebut dikedalaman tertentu.
Hasil analisis didapatkan persebaran nilai resistivitas dari 20 - 1203 Ωm,
sedangkan nilai chargeabilitas dari 10.3 - 300 msec. Untuk resistivitas ˂50 Ωm
diinterpretasi sebagai batupasir, resistivitas 50-200 Ωm diinterpretasi sebagai
batupasir breksian, resistivitas 200-500 Ωm diinterpretasi sebagai breksi, dan
resistivitas ˃500 Ωm diinterpretasi sebagai batuan beku. Untuk chargeabilitas,
keberadaan mineral logam terdapat pada chargeabilitas sedang - tinggi yaitu ˂176
msec. Banyaknya sumberdaya mineral logam didapatkan sebesar 31,919,460 Ton.
Kata Kunci : Induced Polarization, dipole-dipole, resistivitas, chargeabilitas,
mineral logam
ABSTRACT
ANALYSIS OF GEOELECTRIC DATA INDUCED
POLARIZATION (IP) METHOD TO KNOW THE
DISTRIBUTION OF METAL MINERAL IN THE “FK” AREA
USING DIPOLE-DIPOLE CONFIGURATION

Research on the analysis of geoelectrical data using the Induced
Polarization (IP) method in the "FK" area. Stratigraphically, the study area is
composed of Alluvium, Flower Basalt, Sukadana Granite, and Kerabai Volcano.
The tectonic events in Kalimantan have caused an abundance of natural
resources in the research area, including metal minerals. This study aims to
determine the distribution and size of metal mineral resources in the "FK" area.
In this study using 8 tracks with a spacing between the electrodes of 20
meters. The direction of the measurement path orientation is north-south with a
track length of 580 meters. The data processing stage is by using Res2Dinv
software to obtain a 2D resistivity and chargeability cross-sectional model, then
3D modeling is carried out to determine the amount of metal mineral resources in
the research area. From the 3D model then depth slicing is carried out to
determine the presence of these metallic minerals at certain depths.
The results of the analysis obtained a distribution of resistivity values from
20 - 1203 Ωm, while the chargeability values were from 10.3 - 300 msec. The
resistivity of ˂50 Ωm is interpreted as sandstone, resistivity of 50-200 Ωm is
interpreted as breccia sandstone, resistivity of 200-500 Ωm is interpreted as
breccia, and resistivity of ˃500 Ωm is interpreted as igneous rock. For
chargeability, the presence of metallic minerals is found in moderate to high
chargeability, namely ˂176 msec. The amount of metal mineral resources
obtained was 31,919,460 tons.
