Abstract
Utilization of land use in the Daerah Istimewa Yogyakarta Province resulted in an increase in subsidence and reduced grounwater recharge area of rainwater in catchment areas. The aim of this study was to determine the area of agricultural land were converted to housing, other infrastructure, and the mining area during the last 5 years as well as to analyze changes in the hydrological system due to land conversion, especially the water supply to the area of the aquifer. This study is a summary based on secondary data collection, observation and description in the field, measurements of rock permeability and infiltration, as well as laboratory and studio work. Employment in the field also observed for conversion of land use that occured and compare the physical properties of rocks before and after conversion. Evaluation is emphhasized on the water balance equilibrium calculation has been calcutaled on the amount of percentage changes in land use and analysis of the impact of the conversion of land use in the catchment area to change the content of groundwater. Based on the results of the calculation of the projected of grpundwater due to land conversion, water reserves and ilfiltrasion volume continued to decline from year to year. This study is expected by the general public is expected to use the existing land well and wisely with regard to groundwater reserves so that it can be minimize the reduction in water reserves and ilfiltration from year to year.
