摘要：The development of Semarang city requires the availability of water for daily use and industry in line with population growth. Uncontrolled use of water will damage the groundwater system. The purpose of this study was to determine the zone of the decrease of water level to obtain information about area that utilizes excess water. The method used is a micro-gravity vertical gradient between times. Gravity measurements were done at 124 points spread evenly between May and October 2013. The results showed that there was a decrease in ground water level in the Industries area Kaligawe, Tanah Mas, and Tlogosori which was identifi ed with the vertical gradient anomaly of micro gravity between the times from May to October 2013. The regions which have high negative changes in ground water level (1.2-1.4 m / year) were the monitoring wells Madukoro 2, LIK Kaligawe and PT Aquaria which are the industrial areas. Exploitation of ground water in industrial areas is relatively high compared to the other regions.
