Abstract

The relocation of the capital city of Indonesia from Jakarta to Ibu Kota Nusantara (IKN) would be followed by a migration population. The new capital city of Indonesia is located in Penajam Paser Utara and Kutai Kartanegara Regencies, East Kalimantan. This center of population activity causes clean water needs to increase. The main source of clean water to support the basic needs of the population is groundwater. To find out the presence of groundwater, early identification is needed to carry out before field checking. The identification is using remote sensing data from DEMNAS. The data is processed and analyzed for its morphometric characteristics to indicate the potential zone of groundwater, from low to high potency. The morphometric aspects used are linear, relief, and areal. Based on the analysis, the southeastern areas of IKN have high potencies of groundwater than the northwestern areas. The low potential zone groundwater in the northwest area of IKN needs special attention because it is the National Capital Area (KI-IKN).

Keywords: Ibu Kota Nusantara, morphometric analysis, groundwater potential zone.
