| Summary: | Extraction groundwater is one of the cause of land subsidence in DKI Jakarta. The purpose of the research is to determine the relationship between land subsidence with decresed of groundwater level. If the groundwater drawn increasly it will cause intergranular region will be empty. The tendency for the rate of decline in each point of observation is determined based on a graphical model with pearson product moment correlation method and spatial model with interpolation method. The model generate in this research will be used to determine the correlation between land subsidence with decreased groundwater level. Both have a positive correlation between 0.8-0.9 with a correlation coefficient of average 0.875, the value included is very strong category. Based on result of graphical model obtained equation function between land subsidence (y) with decreased groundwater (x) is y=14x, that is when the soil has decreased into 1m, groundwater level will decrease into 14m. The spatial model explain the region main a significant decline in land subsidence and groundwater level occurred in the area of Jakarta, exactly in Kapuk, Tanjung Priok, Pluit, Sunter, and Kelapa Gading, while the surrounding area has decrease relatively small. |
