Abstract
Penelitian ini berada pada daerah Wundulako Kabupaten Kolaka Provinsi
Sulawesi Tenggara yang merupakan salah satu daerah di Indonesia yang kaya
akan mineral. Metode yang digunakan dalam penelitian ini yaitu metode geofisika
Induksi Polarisasi konfigurasi dipole-dipole. Metode ini merupakan salah satu dari
metode geolistrik yang bersifat aktif biasanya sering digunakan untuk mendeteksi
mineral logam bawah permukaan. Konsep pada metode ini dapat mendeteksi
adanya polarisasi yang terjadi pada permukaan mineral logam ketika arus listrik
diinjeksikan kedalam bumi. Pada daerah ini diperoleh lintasan sebanyak 15
lintasan membentang dari timur laut-barat daya, yang masing-masing lintasan
mempunyai panjang 155 meter dengan spasi 10 meter dan diperoleh slope dari
lintasan 1-15 rata-rata 200.
Data yang diperoleh dilapangan kemudian diolah menggunakan software
Res2dinv, dimana pada pengolahan tersebut didapat paramater resistivitas dan
chargeability. Nilai resistivitas rendah dengan rentang nilai 0-200 ohm.meter saya
interpretasikan sabagai batuan metasedimen dan nilai >200 ohm.meter saya
interpretasikan sebagai batuan metamorf.
. Dari hasil penelitian yang dilakukan dengan metode induksi polarisasi,
mineral logam memiliki nilai Chargeability >100 Msec yang merupakan batuan
metasedimen dan batuan metamorf yang mengandung mineral logam. Terletak
pada lintasan 1,2,3,5,7,8,9,11,12,13 dan 14 yang berarah barat, utara dan selatan
pada daerah penelitian.
Kata kunci : Induksi Polarisasi, Resistivity, Chargeability, Mineral logam
Research is located on the Wundulako the District of Kolaka in Southeast
Sulawesi, which is one area in Indonesia are rich in minerals. The method used in
research, which is the method of Geophysics Induced Polarization configutation
Dipole-dipole. This method is one of geoelectric that area active are often used to
detect minerals metal below the surface. The concept at this method can detect the
presence of the polarization that happened on the surface of the mineral
metalwhen the flow of electricity is injected into the earth. In this area by the track
as much as 15 line stretches from northeast – southwest, which each of the length
of 155 meters with a space 10 meters, and slope of the track 1 – 15 approximately
200.
The data obtained in the field then processed using software Res2dinv,
where in the processing of the provided parameters resistivity and chargeability.
The resistivity low with a value 1 – 200 ohm.meter I interpretation as rocks
metasedimen and the value of > 200 ohm.meter I interpretation as rocks
metamorf.
From the results of research conducted by the method of an induced
polarization, mineral metals have value chargeability >100 Msec which is a rock
metasedimen and rocks metamorf that contain mineral metals. Located on the
track 1,2,3,5,7,8,9,11,12,13, and 14 the direction the west, north, and south on the
research area.
Keywords: Induction polarization, resistivity, chargeability, Minerals metals
