Publisher : Natural B, Journal of Health and Environmental Sciences

A research using remote sensing have been done on Kawah Wurung-Ijen. This research was conducted to analyze the distribution of land surface temperature and to identify the geothermal manifestations. The land surface temperature was obtained by using emissivity method of calculating the Normalized Difference Vegetation Index (NDVI). Remote sensing data was used more secund data from Landsat 8. The result shows that the research area has the land surface temperature distribution in ranges 10°C to 50°C. The interpretation shows any anomalous area in ranges 31°C to 50°C that indicated as geothermal potential area. The anomalous are associated with volcanic areas. In the West is associated with Mt. Genteng, in the North is associated with Mt. Gending Waluh. In addition, there is also an anomaly in the East precisely around kolovium of Mt. Kukusan.

Geoelectrical Tomography of Cangar Hot Springs Area, Arjuno-Welirang Complex Stone Fajar Rakhmanto; Sukir Maryanto; Adi Susilo

Have been research geothermal of Arjuno Welirang area of East Java with geoelectric resitivity tomography. Geoelectric tomography was performed by VES (Vertical Electrical Sonding) and Mapping. Acquisition of data totaled 7 points of VES and 4 tracks Mapping was located surrounding the hot springs.Results of geoelectric resistivity modeling showed the resistivity of rock layers the carrier fluid (water) heat <10 Ohm.meter, while a layer of carrier fluid (water) was worth 10-100 Ohm.meter. The hot fluid coming from the direction of CR4 and CR3 are located in the south from the hot springs with a depth of 24.7 meters from the ground CR 3 (see Figure 5) which alleged a layer of sand, with layers of lava rock in the form of heat source at depth 34 meters. Mapping the results of modeling that consists of 4 tracks show around hot springs artifacts crack / crack is suspected as a medium to hot water flow out of the ground surface, precisely located at CANGAR_LINE1.

Local Fault Line Tracing in Sri Mulyo Village, Dampit Sub District, Malang Regency Based on Geophysical Data Wasis Wasis; Sunaryo Sunaryo; Adi Susilo
Natural B, Journal of Health and Environmental Sciences Vol 1, No 1 (2011)
Publisher : Natural B, Journal of Health and Environmental Sciences

A research has been conducted for searching local fault at Sri Mulyo Village, Malang Regency, to get the physical parameters of 3-dimension fault, which include depth, width, length, and direction. The research is based on the preliminary research that results geological data interpretation, gravity, and outcrops. The survey used resistivity parameter by applying pseudo-depth section configuration (4 electrodes). Data processing and interpretation using inverse method. By combining every pseudo depth section, 3-dimension physical parameters will be acquired square error is 2.51x10-27.

Mechanism Focus of Volcanic Type A Earthquake at Mount Semeru, East Java - Indonesia Kartika Andryana; Sukir Maryanto; Adi Susilo; Hetty Triastuti

Publisher : Natural B, Journal of Health and Environmental Sciences

Study of the focal mechanisms of A-Type Volcanic earthquake (VA) Semeru has been done to know the volcanic activity in more detail, until the information about the magma migration process. The study began with the selection of seismic events that has a clear appearance, continued with the conversion value in the instrument readings and the amplitude correction which includes the correction of propagation effect and local effect. Hypocenter distribution showed that the epicenter was dominant in the northwest direction, relative to the central volcano, with a depth between 1-13 km. Interpretation of the hypocenter distribution, supported by past research as well as geological information around, gave initial estimates that there was a column of magma flow that leads from the northwest to the center of the crater. VA study of earthquake focal mechanism illustrate that the dominant type of normal fault occurs at the peak of eruption, and would change to reverse fault after the activity dropped to normal. From the research, VA earthquake in G. Semeru could be classified into two types: deep VA (VAD) with a depth range of more than 6 km and the shallow VA (VAS), with a depth of 1-6 km.
