Abstract

The rise of coal mining in the East Kalimantan area which is close to public road access is thought to affect the quality and sustainability of surrounding public road access. The aim of this research is to determine the use of remote sensing data to analyze land subsidence or deformation that occurs on the connecting road between Sanga-Sanga Dalam Village and Pendingin Village, Sanga-Sanga District, Kutai Kartanegara Regency. The method used in this research is quantitative descriptive, namely determining ground deformation on roads obtained by analyzing Sentinel-1 imagery in 2015 and Sentinel-1 imagery in 2021. Ground deformation can be identified using a satellite-based remote sensing method through interferometry of two SAR images (interferometry synthetic aperture radar or InSAR) uses the Sentinel application platform (SNAP) which is an open source software (FOSS) application. Interferometry can represent changes in the line of sight between the ground and satellites in general. Changes in line of sight can be interpreted as signals of ground deformation. The results of this research can provide adequate information regarding comparative data on land elevation on the Sanga-Sanga Dalam - Pendingin road from several points experiencing land subsidence or deformation on average of 161.3 cm with an average land subsidence rate of 23.04 cm/year . Thus, remote sensing technology using the InSAR technique can be used to determine changes that occur in a short time and at low cost.

Abstract

This research is motivated by the growth of population and its activities. The increasing population and the more intensive activities of people in a place have an impact on changes in land use. One thing shown is changes in the Karang Mumus River Watershed (DAS) sub-area in Samarinda. Samarinda is one of the cities that is developing with a population that is increasing every day and has a variety of urban activities which are not small, causing the need for space is also not small. This research aims to identify land use and land use changes in the Karang Mumus sub-watershed. The method used in this research is the Geographic Information System (GIS) method, to process and analyze data so as to obtain information, types of land cover, area and changes in land use in the Karang Mumus sub-watershed in 1990, 2000, 2011 and 2020. Results from this research, over the past three decades, there has been a significant decrease in the area of dry land forests, while residential areas and the mining sector have seen rapid growth. The loss of dry land forests potentially disrupts ecological functions, including carbon absorption and serving as habitats for various species, which can impact ecosystem health and biodiversity. The expansion of residential areas and mining without proper management and planning poses environmental risks, including erosion, pollution, and potential degradation of water resources and air quality.
