Searching Ground Water Sources by Geoelectric Method for Tourism Development in Taman Harmoni Bali Bukit Asah Bugbug Karangasem regency, Bali Propince

Abstract— Taman Harmoni Bali Bukit Asah (THB-BA) is place located in Bugbug Village, KarangasemRegency, BaliProvince. Geographically located at 8,50057480 S, 115,60045930E. This tourism place has a beach, the name is Bias Putihbeach, people call it Virgin beach. The visitor from month to month continue to increase. This place also has a camp with an axotic view. Even though this exotic destination is so exotic, it still has weaknesses, namely the lack of water availability. While this is still riding in a local water supply group, so the water is still very far from enough, especially for camping, visitors in general, and plant maintenance. For this reason, it is necessary to find a solution so that the Taman Harmoni Bali Bukit Asah (THB-BA) can grow rapidly. One method that is often used to find groundwater sources is the geoelectric method. Research on the search for groundwater sources in THB-BA has been carried out from March 2018 to July 2018. The geological state of the study area is mostly in the form of rocky aluviun soils, which makes it difficult for site selection. Based on the surface geological conditions, a survey was carried out near the Bias Putih beach. A good source of water was found at a depth of 22 m. Later drilling, water was found starting at a depth of 9.5 m. Then drilling continues to a depth of 31 m with a screen starting at a depth of 23 m because the position of good water is estimated at a depth of 22 m. The existence of this water has also been tested, it turns out that it is true that there is water.
