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.

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.

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.

The study area is a tin mining region in hundred years, located in Bangka Island, Bangka BelitungArchipelago Province. Identifying geo-disaster potential, in order that to know the the type, spatialdistribution of geo-disaster that caused by geogenic or antropogenic factor. The research is done byobserving all of geo-disaster potential, with geological and geomophological additional condition. Geodisasterpotential is ilustratrated in a map as result of work using geographic information system (GIS)software that is supported from Landsat TM7 analysis. Erosion, sedimentation, lanslide andabration disaster mainly caused by antropogenic factors from tin mining activities and landfarming, butfor dryness, flood, hurricane and earthquake caused by geogenic factors. For flood and dryness alsoinfluenced by antropogenic factor. Dryness, erosion and sedimentation has the large spatialdistribution in Bangka Island.

The reserves calculation is one of the early stages before the mining operation, which begins with thesamples prediction. Ordinary kriging is a part of the kriging method that works with semivariogramparameters. The calculation of these parameters based on several things, including thedetermination of the lag distance and the fitting model. This paper is based on the determination of themaximum lag distance of 500 and 800 where the lag distance for both, respectively 15, 25 and 35 withWLS and OLS fitting models. The six combinations can be concluded that increasing of maximumlag distance adds to a large of sill and extend the range. OK prediction shows that the largest goldgrade mean (5.032) occurs in the kriging using WLS fitting models, in which the maximum lag distancesemivariogram is 500 and the distance of each lag is 35.

Underground water is a component in the hydrological cycle, formed by rainwater that seeped into thesoil and flows through the media layer of rock (aquifer) in groundwater basin. Wates basin’sgrounwater includes the Wates District, Temon, Panjatan, Lendah, Brosot, a little part of the DistrictSentolo and Pengasih located in Unit Plateau of volcanics fluvio, beach units and sand dunes with thealluvial material consisting of sand, gravel, silt, and clay, flat morphology, relatively lithology andgroundwater characteristics. This lithology is potential with the occurrence of groundwaterconservation system changes, if there is excessive ground water extraction in the region which can becharacterized by the increase in salinity in ground water. The main objective of this study is to assessthe full qualitative and quantitative groundwater in the Basin Groundwater Wates International Airportdue to Temon airport construction in relation to maintaining the sustainability of groundwater systems.The methods in this study consists of several steps, starting from observation and rock’s/soildiscribtion include: measurement of rock bedding, measurement of geological structural elements,observation of morphological conditions, and sampling soil / rock to be tested in laboratory about thecontent of the mineralogy, texture and structure. Observation of surface water and groundwater isdone by testing the physical properties of the surface water include: smell, taste, turbidity, temperature(T), acidity (pH), electrolit conductivity (EC), and taking water samples to be tested in the laboratory todetermine the elements it contains a chemical that results will be used to created Diagrams Stiff andTrilinier. Estimation of resistivity (geoelectric) was conducted to determine the condition of the soil/rockbelow the surface to a depth of more than 75 m, with the aim to determine the configuration of theaquifer both laterally and vertically, the results of which will provide an overview/three-dimensionalcross-section of the local groundwater system deposits carefully situations and recharge area. Thecross-sectionwill shown information quantity/amount of groundwater and the identification of the coasttowards the potential intrusion of sea water. The results of mineralogical analysis of rocks andhydrochemical groundwater will provide information on the distribution of groundwater quality. Thisquality conditions will certainly change with the start of construction of the airport and afterconstruction of the airport. Information about the mineralogical content of rocks, hydrochemicalcontent of water and aquifer configuration will be able to contribute to efforts in the area ofgroundwater International Airport Temon, DIY.
