Abstract

Bromo mountain is one of the most active volcanoes in East Java. In December 2015 - January 2016 the Center for Volcanology and Geological Hazard Mitigation detected increased activities on Bromo mountain. The existence of volcanic activities cause a deformations on the surface of Bromo mountain. The existing deformations on the surface of Mount Bromo can be measured with various technologies such as using DInSAR. In this study, the analysis of deformation on the surface of Mount Bromo are done by DInSAR processing using two-pass method and using five Sentinel-1A satellite imagery in November 2015, December 2015, January 2016, February 2016, and March 2016 and DEM SRTM 30 meters. The results show that the two-pass method of DInSAR can reflect the increased activities in Bromo mountain that cause the deformation of the surface where the majority of deformations occur at the caldera of Bromo mountain. From this method, the result of LOS (Line of Sight) displacement value indicates that the maximum subsidence occured in December 2015 - January 2016 with the value -20 mm s / d -60 mm it indicates if there were some increased activities on the crater of Bromo mountain in December 2015 to January 2016. While the maximum uplift occurred in February 2016 - March 2016 with the value 0 mm s / d 40 mm it indicates if the activities on the crater of Bromo mountain was decreasing. However, in order validate the accurate value of deformation, it is necessary to compare with other measurements or measuring directly in the field

Abstract

Water is natural resources that is very essential for living creatures and the environment. Along with the increase of population , will increase the water demand and reduce the area of free land / open green space for the formation of ground water. By considering soil water conservation aspects, it is necessary to conduct a study of the recharge area on water basin soil in Pasuruan. This study was to determine the condition of the recharge area in the Basin Groundwater Pasuruan in 2003 and 2014. So it will be k[1]nown the changes of the vegetations density and land cover in the recharge area that can affect infiltration process in order to conserve water resources in CAT Pasuruan. From these changes it would be able to make the prediction of future conditions in the recharge area in CAT Pasuruan. This study uses Remote Sensing using Satellite imagery Landsat and Geographic Information System (GIS). Studies to determine the recharge area is influenced by several parameters, that is slope of land, lithology and Rainfall. Processing results obtained vegetation density changes of the recharge area in 2003-2014, high vegetation density decreased by 4330,89 Ha, so that changes in the high vegetation density in 2025 is predicted to be 52305,39 Ha and become 52176,78 Ha in 2030. While land cover changes produce changes in forest land cover increased by 569,88 Ha , so that changes in forest land cover in 2025 is predicted to be 37563,88 Ha and became 38720,494 Ha in 2030. The relationship between vegetation density and land cover of the recharge area in 2003 - 2014 obtained high vegetation density that experienced an increase area, which is on garden land cover amounting to 1144,80 Ha, 943,02 Ha of forest, 947,79 Ha of settlements land cover and 262,53 Ha of vacant land. And that experienced an increase with low vegetation density are the fields amounting to 943,02 Ha and 277,47 Ha of vacant land.

Abstract

The eruption of Mount Sinabung in 2010 caused bursts of volcanic ash particles into the atmosphere layer to impact the weather. This is because volcanic ash is hydrocopic which can cause condensation process and block the process of solar radiation earth surface. Precivitable Water vapor (PWV) as one of the parameters of the atmosphere that can be used as information to determine the weather conditions in an area. Utilization of data Sumatran GPS Array (SUGAR) and data satellite Terra sensors MODIS (Moderate Resolution Imaging Spektroradiometer) can be used to find out PWV through GPS inversion method by utilizing estimated estimation of slowing and rotating GPS signals overlaid with troposphere. While the transmittance method is performed by comparing the surface reflectance between the channel absorption and the channel non absorption contained in the sensor MODIS. The results showed that spatial variation of PWV distribution pattern showed wetness pattern during eruption. This was indicated by some areas that have PWV distribution pattern almost in each region and PWV verification result from GPS showed ± 47.65 mm-66.81 mm, while PWV value from MODIS ranges from ± 13.02 mm - 80.05 mm. Based on the results of PWV-GPS correlation test from June to October of 2010 has a correlation coefficient of 0.0173 to PWV from MODIS and explains the positive relationship between PWV of GPS with PWV value from MODIS, but correlation value of the variable variables including low category because of location points Station SUGAR are spread unevenly and are more likely to spread along the western coast of Sumatra, which borders the Indian Ocean.
