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

Abstract

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.
