Magnetic and Gravity Methods to Analysis Geological Structure and Its Correlation to Groundwater Potential Zone in Lebakwangi Kuningan West Java

Lebakwangi District is one of the subdistricts located in the eastern part of Kuningan city that often have scarcity of groundwater problem. Geological structures encountered in the research area in Lebakwangi District, Kuningan Regency, West Java Province, is a symptom of regional dispersal of structures. The purpose of this research is to know the effect of geological structure on the aquifer in the research location and to analyze the influence of geological structure to groundwater flow in the research location. From Gravity and Magnetic data processing, it can be obtained that there are indication of structure in research location, pattern of structure (fault) and straightness that have direct relative northwest-southeast, which is similar to the pattern of straightness and its regional structure. The recharge zone is estimated to be located in the west of the research location (ciremai mountain area) flowing into the discharge zone in the eastern area (research location) but the difference in groundwater condition is suspected to be related to the presence of existing structures at the study site
