Abstract

DKI Jakarta is experiencing land subsidence due to overexploitation of its use and the increasing population. It is feared that this decline or deformation will occur in the location of the new national capital. The research objective is "Mapping of Land Surface Deformation using PS-InSAR for Disaster Risk Management in the Future." Quantitative and qualitative research and data collection methods use secondary and primary data. Secondary data in the form of Permanent Scatterers Interferometry Synthetic Aperture Radar (PS-InSAR) Sentinel-1A images to determine soil deformation. Primary data uses a questionnaire to assess disaster risk management. Data analysis uses spatial and statistical analysis. Spatial analysis for land deformation mapping and statistical analysis for risk management. The results showed that the pattern of land deformation before the determination of the location of the capital city of Indonesia was random. On the other hand, after decision-making, it appears to be more systematic and homogeneous in adjacent areas with a decreasing range of about 5 cm per year. Other findings show that disaster risk management carried out by several agencies, especially the problem of land deformation in East Kalimantan, is still far from expectations and very minimal. The findings can be used for future disaster risk management to minimize negative impacts and reduce disaster risk.Keywords: PS-INSAR; Land Deformation; Capital City; Disaster Risk Management

Abstract

The planned relocation of Indonesia's national capital from Jakarta to East Kalimantan, particularly to Penajam Paser Utara and Kutai Kartanegara Regencies, is expected to substantially transform the region's social, economic, and cultural landscape. This study examined the baseline characteristics of local and indigenous communities within the Nusantara Capital City (IKN) development area, focusing on education, livelihoods, language, economic conditions, and land ownership. A mixed-method approach combining qualitative description and quantitative analysis was employed. Data were collected through documentation and surveys involving 200 purposively selected respondents from Sepaku, Pemaluan, Teluk Dalam, Babulu Darat, and Babulu Laut, all of whom had resided in the area for at least five years. The findings reveal a socioeconomically diverse community, with 45% of respondents completing senior high school and only 5% holding bachelor's degrees. Agriculture remains the dominant livelihood, employing 45% of respondents, while Indonesian serves as the primary lingua franca among Javanese, Bugis/Makassar, and indigenous Paser/Bali communities. Sepaku recorded the lowest average monthly expenditure (IDR 345,000), indicating limited purchasing power and potential vulnerability to marginalization. Emerging challenges include land ownership disputes, social tensions, theft, flooding, and limited access to clean water. These findings highlight the importance of culturally sensitive policies, community empowerment, and infrastructure development to ensure that indigenous and local communities benefit equitably from the IKN transformation.
