Application of Geographic Information Systems for Analysis of Rice Agricultural Land Resources Potential in Paser Regency as a Supporting Area for the Capital City Nusantara

Abstract

The relocation of the State Capital from DKI Jakarta to the Ibu Kota Nusantara (IKN), East Kalimantan brought new problems, one of them was agricultural problems. The increase in population in IKN also increases the need for food which threatens food security. East Kalimantan region, which is mostly peatland and plantation land, is not suitable for use as rice farming land, so it is necessary to analyze the potential of rice supporting areas for IKN to ensure food needs in IKN are met. Areas that support IKN rice include Paser Regency, North Penajam Paser Regency, and Kutai Kartanegara. This study aims to analyze the potential of natural resources in one of the IKN buffer areas, namely Paser Regency as a food supply area, especially rice. The parameters to be analyzed are land cover, soil type, topography, and slope. The analysis was carried out using a geographic information system (GIS) with the overlay method so that potential areas were obtained to be developed as rice farming areas so that they could meet the food needs of IKN. The results of the overlay analysis of Paser Regency obtained 3 classifications of potential land for agriculture. Land with no potential is 242.22 km 2 , quiet potential is 5,779.42 km 2 , and very potential land is 4,230.51 km 2 .
