Abstract

Rice is a very important because it is a source of carbohydrates besides corn, sago, wheat, cassava and taro. Paddy produces rice which many Indonesians use as their daily staple food. Bantaeng Regency is one of the regencies that has developed a lot of rice commodities. However, this commodity has experienced a decrease in harvested area and production from year to year for the last 3 years, thus attracting attention to assessing the land suitability of the area. The stages of this research are: 1) Collection of secondary data and base maps such as climate data, administrative maps, geological maps, soil type maps and land use maps, 2) Making land unit maps from the base map overlays, 3) Survey introduction, 4) Sampling and analysis of soil samples in the laboratory, 5) land potential assessment. The method used in this research is quantitative analysis using the SPKL application (land suitability assessment system) version 2.0. The research results obtained are land suitability class S3 (according to marginal) at all observation points of the soil profile with the limiting factor of base saturation on all soil profiles as well as P2O5 and K2O on profile 2. Limiting factors such as base saturation, P2O5 and K2O can be overcome by liming, fertilization and organic addition
