Abstract

Electrical Resistivity is one of the geophysical methods that can detect the flow of electricity below the earth’s surface. This study aims to determine subsueface lithology, determine the potential of groundwater and determine the location of prospective drill sumut placement in the tourist attractions of Rammang-Rammang, Bontoa District, Maros Regency. This research uses electrical resistivity method with Wenner and Schlumberger configuration. Processing data using Res2DinV to map subsurface 2d isoresistivity. From the results of this study the resistivity value is different for each rock starting from 2,36 – 40434 Ωm the resistivity value of fresh water is in the range of resistivity value 30 -100Ωm. Subsuface lithology in the area namely alluvial, limestone, hollow limestone and limestone with massive structure.From the interpretation of the measurement data made at the study site, the location of the prospective well bore for drilling is located at coordinates, trajectory 1 119036'37.154"E, 4055'26,413"S with aquifer thickness 8,75-112 meters. Lane 2 on coordinates 199036'42012 E, 4055'26,456”S then 119036'37.055 "E 4055'35,680"S and 11903636.208"E, 4055'37478"S.

电阻率法是一种地球物理方法，可以探测地表以下的电流。本研究旨在确定Maros Regency Bontoa地区Rammang-Rammang旅游景点的地下岩性，确定地下水潜力，并确定未来钻探sumt的位置。本研究采用Wenner和Schlumberger配置的电阻率法。利用Res2DinV处理数据，绘制地下二维等电阻率图。从研究结果来看，从2,36 ~ 40434开始，各岩石的电阻率值不同Ωm，淡水的电阻率值在30 -100Ωm范围内。区内地下岩性主要为冲积岩、灰岩、空心灰岩和块状构造灰岩。根据研究现场测量数据的解释，拟钻探井的位置位于轨迹坐标1 119036′37.154”E, 4055′26413”S，含水层厚度8,75-112米。第二车道，坐标199036'42012 E, 4055' 26456 "S, 119036'37.055 "E, 4055'35,680"S和11903636.208"E, 4055'37478"S。巷3为坐标119036′22.323”东经4055′31583”南经和119036′24,626”东经4055′30,083”南经，含水层厚度为2,50-31,9米。
