Abstract
Administratively, the study site is located in the Mutiara, samboja district, kutai kartanegara, east kalimantan province, UTM coordinates are located at (Uniersal Transverse Mercator) zone 50S area of research located in : 507094mE - 51000mE and 9895000mN -9898000mN to the area carefully situations 15km2 (3x5 km). Research area can be divided into three (3) units of geomorphology, namely : the shape of the structural origin of landforms eroded hills (D1), the form of fluvial origin with body landform river (F1), and foodplain landfrms (F2). Drainage pattern that develop that reflects that the research area has the same resistance rocks and sedimentary topography horizontal or oblique and catagorized as young geomorphology stadia. The litology of the area consists of units claystone balikpapan, units sandstone kampungbaru, and units preciptation alluvial. Between units claystone balikpapan and units sandstone kampungbaru stratigraphic relationship are not aligned because of differences in the time gap, and then on th top of unit sedimented sandstone. Kampungbaru are not eligned with alluvial precipitation. Based onfield observation sand drill log's analysi, research area consists of two different lithologies so that can affect the type of aquifer production wells contained on. in the form of free aquifer and aquifer pressure. The ability of lithology and the presence of underground water, the research area contained groundwater flow through the spaces between the grains which have sandstone lithology, quartz sandstone, siltstone and claystone. Based on an analysis of testing slugtest permeability values obtained (K) between 0,1123.10-5 - 2,6344 x 10-6 m/sec, the value of transmissivity (T) betwen 1,301 x 10-5 - 5,405 x 10-6 m/sec, and storage coefficient (S) between 34,77.10-6 - 61,77.10-6. Keywords: Aquifer and Method Slugtest
