Land suitability evaluation for specific uses can be prepared based on land conditions, in this case for paddy plants, which are the basic staple food of the community. This study aims to determine the land suitability for paddy, determine land balance which is based on the area of paddy fields and built-up land to determine the potential of existing land reserves, and to determine paddy productivity. The research was conducted in Banyumas Regency in three districts, Kedungbanteng, Patikraja, and Purwojati as sampling area. The methods used in this study are land suitability analysis with the land unit approach method and land suitability based on SPKL version 2.0 weighted factor method, land resource balance analysis by calculating the reserve of land resources to determine the amount of paddy reserves, and food security analysis with qualitative descriptive method. The results showed that the land suitability class for paddy in Kedungbanteng District was dominated by class N with the highest value of Ntc/eh/lp of 25,57%, Patikraja District by class S2 with the highest value of S2c of 20,13%, and Purwojati District by class Neh of 51,51%.
