Abstract

Depth analysis of the gravity anomaly source using Spectral Statistical Technique has been carried out in the Godean area, Yogyakarta. This research was conducted to determine the depth of the formation in the study area. This study used 56 gravity acquisition points spread over 2 lines  along 12 km east-west direction. Depth analysis is carried out from the Complete Bouguer Anomaly profile. Spectral Statistical Technique is used as a method of determining depth by calculating the slope of the graph Ln (PS) vs k. The results of these calculations are obtained slope of 2 types of anomalies, namely deep anomalies and shallow anomalies. The deep anomaly has a slope of -9704, while the shallow anomaly has a slope of -279. The depth of the anomalous source in the study area has a value of 770 m for deep anomalies interpreted as Nanggulan formations, and 22 m for shallow anomalies interpreted as the Merapi Muda Volcano Deposition.

Abstract

Water is the main problem in every region that has a rapid population increase, one of which is Wedomartani village, Sleman Regency. This study aims to determine the water reserves in Wedomartani village and find out the direction of groundwater flow in the area. The research carried out by measuring geolectricity method (Schlumberger configuration) survey of 15 very point acquisition with an average stretch of 250 m. The tool used in geoelectric measurement is Resistivity Meter Syscal Jr. The software used in processing is Progress 3.0. The results of data processing is resistivity variations function of depth per point acquisition that will interpreted into rock types and water content. The average resistivity of groundwater aquifers in Wedomartani village is 19.49 Ωm and the average depth of groundwater aquifers in Wedomartani village is 101 m. The direction of deep groundwater flow in Wedomartani village generally leads from north to south and west (in the southern part of the research area.
