Abstract

Uekuli Village Tojo Una-Una Regency, have potential of natural resources such as iron sand that containing mineral hematite which is a basic ingredient on the steel industry. This is evidenced by the deposition of iron sand and iron ore rock outcrops in the area. To determine the magnitude of the potential distribution of the iron ore it has performed geophysical exploration using geomagnetic methods. Research by using geomagnetic done through the stages; acquisition of field data, make corrections IGRF and daily variation correction, modeling using 3D modeling software Mag2dc and with help of rockwork software. Results of the study, found that the magnetic anomaly data has a value range between -120 nT to +160 nT. Magnetic minerals contained in the iron ore is hematite. Estimation volume of distribution of mineral hematite are 377 300 m3.

Abstract

This paper aims to present the regional geological information related to geologic structure on the Bangka island. In this paper the processing done digitally on the image of SRTM (Shuttle Radar Topography Mission) by combining the value of azimuth and altitude in order to obtain the number of alignment able delineated and recognizable become more by incorporating N0oE, N45oE, N90oE and N315oE artificial lighting as well as the value of the slope of the sun at 45o. Based on the interpretation of the results obtained Hillshade and rose diagram direction relative straightness dominant northwest-southeast trending interpreted as a manifestation of the direction stance layers, but it also contained lineament trending northeast-southwest according Margono et al. (1995) a rock folds covering Tanjung Genting Formation and Ranggam Formation, large tilt between 18o-75o and showed great intensity and there is tectonic lineament trending north-south, according to Mangga and Djamal (1994) was a fault and the fault is in the phase of the youngest as well as the fracturing horizontal cut of older faults (Crow , 2005). Straightness morphological pattern of spread and intensity level of tectonic deformation by the force in the research area is obtained by calculating the count lineament density based Geographic Information System with ArcGIS 9.3 in order to obtain density interval straightness into three classes, 0-28.72503662 km / km2 (low), 28.72503663- 57.45007324 km / km2 (medium) and 57.45007325-86.17510986 km / km2 (height) The higher the intensity, the area is assumed to be much deformed and most likely close to the structure geology.

Abstract

The research area is a limestone quarry region prospect, located in Gunung Sudo, Gunung KidulRegency, Special Region of Yogyakarta Province. Safety factor of bench in limestone quarry isextremely determined by rock mass quality. The aim of this research is analyzing of rock massstrength of limestone in the quarry prospect using the Hoek-Brown failure criterion. The researchused quantitative method. To obtain rock mass strength analysis of limestone needs someparameters. The main parameters are uniaxial compressive strength of intact rock, GSI, lithology,disturbance factor, unit weight and application for slope (height). To solve this analysis is assisted byRoclab software. The Roclab is a software program for determining rock mass strength parametersbased on the generalized Hoek-Brown failure criterion. Final result of the research will be used forsafely mine design of the limestone quarry.

Abstract

Geotechnical Aggregate are rocks that can be used as material for a wide range of constructionengineering purposes. The need for geotechnical aggregates increased along with the rapiddevelopment. Required sources of aggregate qualified engineering was good, close to the project siteand has large reserves. This research will be carried out an investigation to get to the source ofgeotechnical aggregate surveying of Geology and Geophysics measurements. Geophysicalmeasurement is working by using of Geoelctric methods with Schlumberger configuration. Geologicalsurvey result obtained is that the material consists of geotechnical aggregate are QTV , Qtvl and TMV ,composition form clastica volcanic rocks , breccias , lava , tuff andesite to basalt. Result ofGeoelectric measurements showed that the potential for geotechnical aggregate form Alluvial rockshaving resistivity values between 2-20 ohm meter , whereas the geotechnical aggregate form intrusiverocks is 30-80 ohm meter . Resource potential Probable amounted to 5,742,453 m3 .

Abstract

Utilization of land use in the Daerah Istimewa Yogyakarta Province resulted in an increase insubsidence and reduced groundwater recharge area of rainwater in catchment areas. The aim of thisstudy was to determine the area of agricultural land were converted to housing, other infrastructure,and the mining area during the last 5 years, as well as to analyze changes in the hydrological systemdue to land conversion, especially the water supply to the area of the aquifer. This study is asummary based on secondary data collection, observation and description in the field, measurementsof rock permeability and infiltration, as well as laboratory and studio work. Employment in the field isalso observed for conversion of land use that occurred and compare the physical properties of rocksbefore and after conversion. Evaluation is emphasized on the water balance equilibrium calculationhas been calculated on the amount of percentage changes in land use and analysis of the impact ofthe conversion of land use in the catchment area to change the content of groundwater. Based onthe results of the calculation of the projected reserves of groundwater due to land conversion, waterreserves and infiltrasiakan volume continued to decline from year to year. This study is expected bythe general public is expected to use the existing land well and wisely with regard to groundwaterreserves so that it can minimize the reduction in water reserves and infiltration from year to year.

Abstract

Ranau Lake as the second biggest lake in Sumatra Island. On Plio-Pleistocene Ranau Volcano(Volcano-tectonic) eruption resulted the formation of Ranau Lake. After the great eruption of RanauVolcano, grow up another volcanoes like Seminung Volcano, and become a Ranau Volcanic Complex.At the foot of Seminung Volcano often showed sulfur gas burst activity which are indicated by thedeath of organism in Ranau Lake. The increasing of burst gas and locally earthquacke to be theprinciple one to predict the possibility of volcano eruption for anticipation and decrease the impact ofvolcano eruption. The research objective was to determain the characteristics of rocks formationsurrounding Ranau Lake using Landsat Imagery.
