    abstract = {Groundwater basin-Yogyakarta, Sleman as part of Sleman, Yogyakarta and Bantul in geomorphology
located at Fluvio volcanics plain units, beach plain units and Sand Dune unit consist of with material alluvial
deposits. This area has a relatively varied lithology and has a groundwater aquifer characteristics. For instance,
lithology has a changing groundwater potential preservation system if there is the excessive extraction of
groundwater in the research area it can be characterised by wide fluctuations in water level and changing in
groundwater quality. The main objective of this research was to determine the recharge area potential in relation
to the preservation of groundwater. The field observation method and description of rock including, the
measurement of strike-dip layer of rock, the measurement of geological structure, the condition observation of
morphology, the sampling of soil/rock to be tested in laboratory related with the mineralogy content, texture
and structure. The physical properties were processed by field tests infiltration and permeability. Based on the
researcher it can be seen that the research area of Pakem and Ngemplak as recharge area were good with the
infiltration rate of 19-28 mm/h and the permeability of 12&times;10<sup>&#150;2</sup> cm/sec.}
