Dokumen (Study of Geohydrology Potential of Urban Area in Sumbersari District of Jember Regency, Indonesia)

The increase of population, housing facilities and infrastructure in Sumbersari District of Jember Regency is significant in
2012. This causes groundwater to raise sharply exploits of 200 liters/ second to 800 liters/second. The long-term goal of this
research was to determine the potential magnitude of groundwater in order to obtain the maximum threshold of groundwater
exploitation. The specific target of this research is to obtain the distribution or flow of groundwater in the urban zone. Prediction
methods groundwater Geo electric potential is subsequently performed using analysis tools for the interpretation of the Geo
hydrological condition Ip2WIN computing based programs. Stages activity is the collection of map of urban Geo
hydrological study, daily rainfall data collection station at least 3 rain, field investigations by means of geoelectric Schlumberger
configuration in 4 area stretching east-west and north-south, the analysis of data in the laboratory with computational software
IP2WIN, calculation of the availability of groundwater, water balance calculation. The Result showed that the maximum limit on
the amount of groundwater exploitation that groundwater sustainability awake and anticipating water shortages or drought is
approximately 2494.125 liter/sec, assuming groundwater making 5 liters/sec in the groundwater wells that may be performed in
the District Sumbersari District Jember is a maximum of 500 groundwater well.
