Daftar Isi:
- Merapi Volcano eruption in 2010 has caused damage to settlements on the southern slope. The Government was then provided temporary housing (Huntara) for the victims of the eruption. Based on the policy of the Government and related institutions, Huntara was then intended to become a permanent housing (Huntap) in an effort to relocate victims of the eruption. Relevant to this, the current study is motivated by the need for information about groundwater potential as a source of fulfillment of domestic needs for the temporary housing and about the strategic plan formulation of groundwater potential management. The objectives of the study are to: (1) determine the groundwater potential in the researched area, (2) determine the groundwater potentials to fulfill the domestic needs of temporary housing, (3) formulate the plan and strategy of groundwater potential management. The primary data employed include the depth of groundwater surface, elevation, groundwater quality, and the amount of water needed by the temporary housing. The secondary data include those of drilling, elevation contours, and other supporting data. The primary data samples were determined on systematic random, proportional random, and purposive bases. Objective 1 was achieved by determining the quantity and quality of groundwater. Groundwater quantity was determined by the method of dynamic discharge, groundwater quality was determined by comparing the results of laboratory testing of groundwater samples to the value promulgated in water quality regulation. Objective 2 was achieved by comparing the quantity of the available groundwater to the amount of water for domestic needs in temporary housing. Objective 3 was achieved by SWOT analysis, where plans and management strategies are subjective concepts that results from the interaction between internal and external factors of groundwater potential in the researched areas. The results were described on quantitative descriptive, qualitative descriptive, and comparative bases. They indicated: (1) that groundwater potential of the researched areas have a predictive value for dynamic discharge of 17.980.174 l/day or 17980,2 m3/day, and that 71% of groundwater is in good quality
