Abstract

Penelitian tentang estimasi sebaran lava basalt berstruktur bantal telah di lakukan di daerah Watuadeg Kecamatan Berbah Kabupaten Sleman D.I. Yogyakarta dengan menggunakan metode VLF (Very Low Frequency) dan metode resistivitas untuk mengetahui variasi nilai rapat arus ekuivalen dan resistivitas bawah permukaan, serta arah penyebaran lava bantal. Pengukuran metode VLF sebanyak 5 lintasan yang berarah Barat – Timur dan 3 lintasan berarah Utara – Selatan. Pengukuran metode resistivitas sebanyak 9 titik dengan setengah panjang bentangan (AB/2) adalah 200 meter dalam area pengukuran 2 km2. Hasil pengolahan data resistivitas menunjukkan nilai variasi resistivitas bawah permukaan adalah 10,9 Ωm– 109  Wm yang diidentifikasi sebagai resistivitas soil, 32,3 Ωm – 122 Ωm diindikasikan sebagai resistivitas tuf, 286 Ωm – 888 Ωm diidentifikasi sebagai resistivitas lava bantal, 112 Ωm – 167 Ωm diidentifikasi sebagai resistivitas aglomerat dan 2,72 Ωm – 36,2 Ωm diindikasikan sebagai resistivitas lempung. Nilai rapat arus ekuivalen (RAE)  di daerah Watuadeg bervariasi antara 60 % - 240 %. Berdasarkan hasil korelasi antar penampang RAE dengan penampang korelasi resistivitas diperkirakan bahwa sebaran lava basalt berstruktur bantal di daerah Watuadeg bersumber dari bukit yang terletak di sebelah Barat kali Opak dengan arah sebarannya menerus ke arah Selatan.

Abstract

Provinsi Maluku Utara terutama pulau Halmahera dan sekitarnya merupakan bagian dari kerangka sistem tektonik Indonesia yang kompleks dan memiliki aktifitas tektonik yang tinggi. Daerah ini berada pada zona pertemuan lempeng Eurasia, lempeng Pasifik, lempeng Indo-Australia dan lempeng-lempeng kecil lainnya seperti lempeng Filipina. Sebagai akibat dari geodinamika maka daerah penelitian merupakan daerah dengan aktivitas seismisitas yang cukup tinggi, dimana faktor utamanya karena terdapat banyak struktur geologi berupa antiklin, sinklin, sesar naik, sesar mendatar dan sesar normal akibat aktivitas lempeng di daerah ini. salah satu metode yang dapat digunakan untuk mengidentifikasikan sesar dan jenisnya adalah metode gravitasi, pada penelitian ini data yang digunakan adalah data observasi gravitasi satelit Topex dengan Luasan area penelitian adalah 3.891,62 km2 dalam bentuk Free Air Anomaly (FAA), yang kemudian dikoreksi bouguer dan koreksi medan menghasilkan Anomali Bouguer lengkap (ABL). Anomali regional dan residual menunjukkan korelasi yang baik dengan peta geologi daerah penelitian dalam mendeliniasi sebaran sesar dengan rentang nilai anomali positif (± 187 mGal) dan anomali negatif (± -14.8 mGal). Analisis anomali SVD menunjukkan sebaran sesar di daerah penelitian adalah jenis sesar turun atau sesar normal.

Abstract

The Naniura NRD300 HF tool has been used in research using the Wenner-Schlumberger configuration geoelectric method to determine the direction of iron sand distribution, the volume of iron sand, and the concentration of iron sand in the Gura beach area. The collected measurement results are then processed by the RES2DINV software into a 2 Dimension (2D) cross-section that shows the distribution values of the subsurface layer as shown by a color image. Once saved in (.xyz) format, the RES2DINV software results are processed in RockWork software to create pseudo-3D cross sections. The RES2DINV software's results show that line 1's resistivity value ranges from 39.6 to 1000 Ωm, whereas line 2's resistivity value ranges from 0.16 to 1.7 Ωm. These findings suggest that line 2 has a lower resistivity value than line 1 does. The volume of iron sand processed by RockWork software is 221,000 cubic meters for linek 2 and 273,000 cubic meters for line 1. The distribution of iron sand deposits in the study region is south to north, based on the volume of iron sand in line 1, which is bigger. A method used to determine the composition of the minerals present in a sample is called X-ray fluorescence (XRF). The results of analyzing the Fe content in line 2 are 55.01%, which is higher when compared to the Fe content in line 1, which is 40.5%.

Abstract

Research has been carried out on landslides in Saluta-Pelita Village, North Galela District, North Halmahera Regency, Indonesia using the Wenner-Schlumberger method using a Geoelectric Resistivity tool - Naunira NRD 300 HF. This research aims to determine the structure of the subsurface layer in the potential landslide area of Saluta-Pelita Village. In addition, this research aims to determine the slip plane (boundary layer) of sea water intrusion in the research area. The measurement results are processed using Res2Dinv software for 2D resistivity which describes the subsurface layer shown in color. The measurement results on track 1 show a clay layer with a resistivity value of 3.1 ohm -27 ohm at a distance of 1-80 meters (blue and green), a silt layer of 44.3 ohm - 184.1 ohm at a depth of 1-20 meters (Yellow) which is a slip plane (boundary layer) of sea water intrusion with a path length of 40 meters, conglomerate 210 ohm (red) at a depth of more than 7.50 meters. In track 2 there is a layer of clay with a resistivity of 1.4 ohm - 39 ohm at a depth of 1-24 meters (blue and green), silt 43.1 m-185.6 m (yellow) is the slip plane (layer boundary) of sea water intrusion with a 95 meter long track, a conglomerate layer with a resistivity of 203.4 ohm - 407.8 ohm (red) at a depth of more than 12.8 meters. On track 3 there is a layer of clay with a resistivity of 0.186 ohm - 31.4 ohm (blue and green) at a depth of up to 24 meters with a length of more than 120 meters, silt with a resistivity value of 44.4 ohm - 189 ohm (yellow) which is a slip plane (boundary layer) sea water intrusion with a path of 65 meters at a depth of 2.50 meters-24.9 meters.
