| description | Semarang City is the capital of Central Java province, located in the northern coast of
Java island, Indonesia which is geologically composed of alluvial deposits. The natural consolidation of young alluvial deposits has caused a land subsidence. On the other hand, load of buildings and constructions causes an increase in the pressure of land surface, and finally, leads to an increase in the rate of land subsidence. The drilling data indicated that not all layers of lithology are soft layers supporting the land subsidence. A research on the depth of soft litology and its percentage of hard lithology has not been conducted ever before. On the other side, an analysis regarding this kind of research can be conducted based on resistivity method. Sounding system method with Schlumberger electrode configuration was selected for field data collection. The goals of this research were to determine the resitivity of lithology so that it can be used to interpretate distribution of depth and clay-silt to sand ratio of land subsidence area. The results showed that the area with the depth of the upper layer of clay-silt less than 3 m and clay-silt to sand ratio less than 4 were the high land subsidence area. |
