Abstract

Investigation of landslide slip surface has been conducted at Salaman Sub village, Pablengan Village, Matesih District, Karanganyar Regency, Central Java Province by using dipole-dipole array geoelectrical resistivity method. Data processing were using Res2Dinv version 3.45 (semi demo version) software. The interpretation result showed that at the research area was found lithology consist i.e. clay, wet clay, sandy clay until claysand, sand until breccia. The slip surface is a wet clay layer with resistivity value range from 19.3 Ω m to 36.6 Ω m, for one section was found with depth of 1.7 meter until 17 meters, and for two section was found with depth of 8.9 until 16.4 meters.

Abstract

It has been done a cross-hole method of field laboratory geoelectrical resistivity to identify the wastewater in Grogol, Gatak, Delanggu, Jawa Tengah. Measurements were performed using McOHM 2119C-EL OYO Resistivity meter. The Anomaly of the object that has given of this research is wastewater. The data acquisition of cross-hole model use dipole-dipole geoelectrical configuration. The distance between the two boreholes is 3 m and spaced electrodes that used are 0,1 m; 0,2 m; 0,3 m and 0,4 m. The Data will be taken from the movement of saline water anomaly that mobiles on the ground and each taking every 4 days for 5 times of the data acquisition. A description of the result of the anomaly will be reviewed using RES2DINV 3.56software. The visualization of the movement of wastewater model on day 4th is at a depth of 0,4 m – 0,6 m at a distance x = 0,5 m - 2,5 m with resistivity 10 - 10,8 Ωm. On day 8th is located at a depth x = 0,5 m – 0,8 m, x = 0,5 m – 2,5 m with resistivity 10 - 14 Ωm. And on day 12th is located at a depth of 0,8 m – 1,2 m at a distance x = 0 m – 0,5 m, x = 2,5 m - 3,0 m and x =1,5m - 2,5 m with a resistivity of 12,4 - 15 Ωm.

Abstract

Identification of temple sites have been performed on the Bukit Carang region atAnggrasmanis, Jenawi, Karanganyar, Central Javausing the geoelectricity resistivitymeasurement with a dipoles configuration method. This method can determine buried sites around the site groundwork. Software Surfer ver 8.0 and Res2dinv ver 3.30b are used to analyze the mapping data and the sounding data, respectively. This research foundelevenanomalies structured andesite’s rock with resistivity of935-1511 Ωmwhich is considered as temple sites.
