"Telah dilakukan penelitian tentang laju penurunan muka tanah yang terjadi di Jakarta pada periode tahun 2018 – 2023. Laju penurunan ini dikorelasikan dengan penambahan volume penggunaan air tanah akibat pertumbuhan penduduk di Jakarta. Volume penggunaan air tanah di Jakarta didapatkan dengan mengurangkan kebutuhan air bersih dengan volume penggunaan air pipa (PAM JAYA) selama tahun 2018 – 2023. Laju pergerakan muka tanah dihitung berdasarkan pengukuran mikrogravitasi 4D yang dilakukan antara tahun 2018 dan 2023. Hasil penelitian menunjukkan bahwa Kecamatan Menteng mengalami penurunan muka tanah cukup tinggi dengan laju sebesar 8.4 cm/tahun dan Kecamatan Jatinegara mengalami kenaikan muka tanah paling tinggi dengan laju sebesar 10.3 cm/tahun. Terdapat korelasi linier antara volume penggunaan air tanah dengan laju penurunan muka tanah di Jakarta. Semakin banyak jumlah penduduk, semakin banyak air tanah yang digunakan, maka laju penurunan muka tanah akan semakin besar.

A study has been conducted on the rate of land subsidence occurring in Jakarta during the period from 2018 to 2023. This subsidence rate is correlated with the increase in the volume of groundwater usage due to population growth in Jakarta. The volume of groundwater usage in Jakarta is determined by subtracting the volume of piped water usage (PAM JAYA) from the total demand for clean water during 2018 to 2023. The rate of land subsidence is calculated based on 4D microgravity measurements conducted in 2018 and 2023. The results show that the Menteng district experienced a significant land subsidence with a rate of 8.4 cm/year, while the Jatinegara district experienced the highest land uplift with a rate of 10.3 cm/year. There is a linear correlation between the volume of groundwater usage and the rate of land subsidence in Jakarta. As the population increases, the more groundwater is used, the greater the rate of land subsidence will be."

"Estimation of land subsidence induced by groundwater extraction has been observed by some researcher using field instrumentation as well as a spatial mapping technique. Among the six Asian cities (Bangkok, Jakarta, Manila, Osaka, Seoul, Taipei and Tokyo), the rate of land subsidence in Jakarta is higher in the period 1900-2010 from the previous study. In order to improve appropriate monitoring system and the comprehensive result for subsidence measurement, tools for subsidence awareness-raising to government and society are needed. This paper aims to study a benchmark and sustainable countermeasure analysis of land subsidence induced by ground water extraction in urban areas of Jakarta city, using continuous monitoring system and integrated data management system. Measuring of land subsidence using field monitoring such as extensometer, leveling survey (GPS geodetic) and observation wells, was conducted in some location in North Jakarta from 1990 to 2016. The result from visual observation reached an average land subsidence rate 1.65 cm/year, while GPS geodetic measurement range from 0-12 cm/year. Monitoring from seven extensometer sensors installed in different borehole elevation reached subsidence 0.66 cm in average. Meanwhile, groundwater surface level ranged at 0.6 meters until 44 meters from surface and the deepest is in Bintaro - South Tangerang area. Data analysis conducted with computer simulation to investigate the inter-connection between land subsidence and groundwater extraction. Obviously, land subsidence has a strong associated with groundwater extraction. Integrated data management systems, including data sharing are needed to improve appropriate monitoring system of land subsidence in Jakarta. "
