Pengaruh Peningkatan Lahan Terbangun Terhadap Penurunan Permukaan Tanah Di Kota Jakarta Utara Tahun 2014-2022
This study aims to determine the effect of increased built-up land on land subsidence in North Jakarta City in 2014-2022. This research uses a quantitative approach and descriptive research type. This research uses remote sensing and geographic information system (GIS) processing techniques using Landsat 8 and Sentinel 1 image data in 2014 and 2022, processing is done through the Google Earth Engine platform. In the variable increase in built-up land, the analysis was carried out using the supervised classification method into 2 classifications, namely built-up land and non-built-up land. And to get the value of land subsidence, DInSAR (Different Interferometric Synthetic Aperture Radar) analysis was conducted. Then to determine the value of the influence between the variable increase in built-up land (x) and the variable land subsidence (y), a simple linear regression analysis was carried out with the equation Y = 6.413 + 13.178X resulting in a significance value of 0.000 <0.05. The R Square value is 0.466 which means that there is an effect of increasing built-up land on land subsidence by 46.6%. While the tcount value obtained a result of 9.239 and the ttable value of 0.1966 and means tcount> ttable. So it can be concluded that Ha is rejected and Ha is accepted, which means that there is a significant influence between the increase in built-up land on land subsidence in North Jakarta City in 2014-2022
