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

The research was around in the Adi Soemarmo Airport area, Solo, Central Java. The growing development and the increased need for water to be basic the importance of this research. The purpose of this research to sources of ground water and state of rocks lithology. This Research using geoelectric method Schlumberger configuration using tools resistivitiy McOHM OYO Model 2119C-EL. The measurements were made much as 6 point sounding, electrode AB/2stretch scattered around the Adi Soemarmo Airport with varying penetration depths ranging from 1.5 meters up to 400 meters with stretch of the electrode reaches 800 meters. Furthermore, the value of resistivity in the field measurements made longitudinal section and water content analysis approached using IP2WIN interpretation software. the results of the study showed that at the point of sounding 2, 1, and 3 at depths greater than 130 meters areallegedly identified the source of ground water and the at point of sounding 7, 4, and 5 over 100 meters.

Abstract

The research on ground water survey by using geo-electric method Schlumberger was conducted at Dayu Village, Gondangrejo, Karanganyar. Geo-electric is one of the geo-physics method which learned about electrical current in or on the earth surface. The equipment used includes resistivitymeter, GPS (Global Position System), roll meter, hammer, electrodes, and cables. Thepurpose of this research is to determine the spread pattern of the aquifer, groundwater potential, the thickness and depth of the aquifer at Dayu Village. The thickness of the shallow aquifer in the area of Dayu is between 3 m to 12 m with a depth of less than 30 m, while the deep aquifer is having a depth of more than 30 m with thickness between 68.5 m up to more than 165.7m.Thereis a degradation of aquifer pattern from Jambu Village (West) to Mulyorejo Village (East).Inversely, we found an increase from Tanjung Lor Village (North) to Watudakon Village(south). Shallow aquifer that potentially contain much groundwater sources located in the village of Tanjung Kidul, Mulyorejo, Jambu, Kedung Ulo and Tanjung Lor. For deep aquiferispotentially found at Pucung village and Kedung Ulo village.

Abstract

Geoelectrical is one of geophysics methods which is used to investigate the early stage in the shallow exploration. The research is conducted at Bledug Kuwu with Schlumberger configuration method containing the two points of potential electrodes and the two points of electrical current electrodes. The equipment used in this research are OYO model 2119C, GPS, meter roll, cable as current and potential electrodes. The purpose of the research is to identify the spreading pattern of salty zone at Bledug Kuwu. The distribution pattern of salty zone is characterized by thickness of 1.55 to 71.9 meters and rangeresistivity of 0.055 to 0.460 Ωm. At west of large Bledug, the salty zone is detected at the depth of 5.0 to 10.0 meters and 30.0 to 50.0 meters. Meanwhile at east of large Bledug, the salty zone is detected at the depth of 5.0 to 15.0 meters and 40.0 to 60.0 meters. The salty zone spread from north to south at both west and east of large Bledug with resistivity of 0.05 to 0.50 Ωm at depth of 5.0 to 50.0 meters.

Abstract

It has been done a research about the determination of rock hardness level by using refraction seismic method in Jatikuwung Karanganyar. The research is done by using Seismograph PASI 16S24-P with the path length of 48 meters, distance between geophone 2 meters, 5 shots in each spread and there are four surveys part totally. The processing data is done by using SeisImager software with Plotrefa and Pickwin95 program.We use intercept time method for data processing. The determination of rock hardness use Gardner’s relationship formula. Based on interpretation, there are three layers lithology structure with P wave propagation velocity of 200-1800 m/s and its density of 1.17–1.93 gr/cc. Based on velocity analysis we determine the velocity of first layer is 200-700 m/s, second layer 700-1500 m/s, and third layer 1500-1800 m/s. The subsurface hardness lithology consists of top soil, sands and unsaturated pebble (1.17–1.59 gr/cc) with the depth 2–4 meters in the first layer, saturatedsands, saturated pebble, and alluvium (1.59–1.93 gr/cc) with the depth 9.5–11.5 meters in the second layer, and clay and sands (1.93–2.02 gr/cc) with the depth of 5.5–6 meters in the third layer. The rock hardness is located at the depth betwen 12 – 20 meters.

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.
