Groundwater Potential in the Candi Abang Area Berbah, Sleman, Yogyakarta Based on Geological Conditions

Abstract

Groundwater is one of the sources of community water needs. Technically, groundwater potential in each area depends on the abiotic components' condition, which are the providers, distributors, and groundwater storage. Groundwater providing, distributing, and storing media are strongly controlled by geological conditions that describe the potential presence of groundwater. The geological conditions of each area are different from one another, so it is important to conduct research on groundwater potential based on geological conditions as one of the basic steps to fulfillment community water needs. Candi Abang area is a hilly area with constituent rocks in the form of pyroclastic products, which make it difficult for groundwater to be stored in it. This condition is interesting to know the groundwater potential as the basis for the fulfillment of community water needs. Research on groundwater potential in the Candi Abang Area was carried out by mapping and direct measurement of geological components, including; landform, soil thickness, lithology, groundwater level depth, rock weathering level, and density of discontinuity fields. Then, analyzed with a weighting method based on the level of influence. The results of the weighting analysis obtained the level of groundwater potential in the Candi Abang area are very difficult, difficult, easy, and very easy.
