Abstract

ABSTRACT. Lokon Volcano is one of 129 active volcanoes in Indonesia that often erupts. The purpose of this study was to determine how the distribution of the surface temperature of the volcano using the Data Image for the period of May 2017, and to find out how the temperature distribution correlates with geomagnetic anomalies. Image data taken at USGS will be processed at Ilwiss software and will describe the surface temperature of the lokon volcano. Geomagnetic data taken from PVMBG illustrates geomagnetic anomalies in the locon volcano. The research results show that the surface of the lokon volcano has a temperature value ranging from 20˚ - 36˚ C. Correlation of temperature distribution with geomagnetic locon volcano data shows the existence of geomagnetic anomalies where there is a smaller geomagnetic anomaly value indicating a lower temperature value. while the low Anomaly value indicates a heat source. Keywords : Correlations, Surface Temperature, Geomagnetic Anomaly.

Abstract

ABSTRACT      Geothermal is energy from the result of heat transfer by conduction or convection. Manifestations in the form of warm soil, steamy soil and hot springs are geothermal energy that reaches the surface. The geothermal system of the Bolaang Mongondow Timur area is controlled by the large caldera structure of Mount Ambang and several fault directions that control the appearance of surface manifestations in the form of solfatara and hot springs. However, until now the geothermal potential has not yet been developed. Therefore, researchers are interested in exploring the geothermal system of the East Bolaang Mongonow area to introduce and increase knowledge about the characteristics of geothermal reservoirs. Based on geothermal field fluid data and fluid content data manifestation of the East Bolaang Mongondow area using geochemical methods (Geothermometer SiO2, Na-K and Na-K-Ca) as well as physical chemical analysis of the fluid shows that the geothermal area of the East Bolaang Mongondow area has a bicarbonate fluid type and sulfuric acid, with the type of reservoir dominated by steam and reservoir temperatures using the Geothermometer equation Na-K (Giggenbach) is 317.12 ° C.  Keywodrs : Fault, Manifestation, Type Of Fluid, Type of Reservoir, Temperature .
