Abstract

The current government through Presidential Regulation of the Republic of Indonesia Number 40 of 2023 concerning the Acceleration of National Sugar Self-Sufficiency and the Provision of Bioethanol as a Biofuel is expanding the land for sugar cane as an effort to meet the needs of sugar in Indonesia, considering that sugar cane is still the main raw material in sugar production. One of the areas prioritized for sugarcane land expansion is Merauke district which is determined by Presidential Decree of the Republic of Indonesia Number 15 of 2024 concerning the Task Force for the Acceleration of Sugar and Bioethanol Self-Sufficiency in Merauke Regency, South Papua Province. The determination of this area needs to be well studied in terms of land suitability. Therefore, it is necessary to analyze and evaluate land suitability in Jagebob District, Merauke Regency so that land use for sugarcane plantations can be utilized optimally and sustainably. Land suitability analysis is carried out using GIS applications by conducting overlay and matching analysis on land suitability parameters such as rainfall, soil type, slope, soil texture and temperature. The data obtained was then analyzed using matching and descriptive methods to determine the results of the land evaluation assessment. Data analysis uses matching and descriptive methods to determine the results of the land evaluation assessment. The results showed that for sugarcane cultivation, the land suitability class in Jagebob District, Merauke Regency is marginally suitable (S3(oa,na)) with limiting factors including drainage (oa) and nutrient availability (na). After improving the limiting factors, the potential land suitability class can move up one level to a suitable land suitability class (S2(oa,na)). Improvement of limiting factors can be done by plowing the soil, applying organic materials and adding doses of P and K fertilizers.
