Abstract

The microgravity 4D research has been canied out in Kaligawe indushial area Semarang to identify subsidence. The research has been carried out two times, namely on Jun 04, Feb 05 using Lacoste & Romberg G1158 gravitymeter which is equipped by alliod to measure gravity on each station and Lacoste & Romberg G508 gravitymeter to observe he tide, The research findings indicate that the research area experience subsidence. This is indicated by time lapse microgravity value that has positive value on Jun 04 - Feb 05. Based on the vertical gradient of gravity time lapse value showed that the subsidence caused by pumping groundwater for industry will give a negative anomaly. The results of gravity measurement show that it's an effective method to identify the subsidence. Keywords : microgravity 4D, subsidence
