Indonesia is the world's third-largest cocoa producer and exporter after Ghana and Pantai Gading. Cocoa is in great demand by people in various parts of the world because Cocoa can be processed into chocolate in food and drinks that benefit the community. One approach that is often used to evaluate cocoa land suitability is a parametric approach with a square root. The square root is part of the parametric approach in evaluating land suitability by assigning a value at a different limiting level to the nature of the land. On a standard scale, it is given a maximum weight of 100 to a minimum value of 0 then the land suitability class calculation is based on the square root. The stages of this research are: 1) Collecting secondary data and basic maps such as climate data, administrative maps, geological maps, soil type maps, and land use maps, 2) Making maps of land units 3) Preliminary surveys, 4) Sampling and analysis of soil samples in the laboratory, 5) analysis of the land and climate suitability, 5) Determination of actual and potential land suitability. The method used in this research is a parametric approach (Square root by Khiddir). The results showed that the parametric method's land suitability class (square root) was N1 (not suitable at present) at the observation points of profiles 1, 3, and 5. In contrast, the S3 land suitability class was found in profile 4. Limiting factors such as annual temperature, slope, soil depth, and coarse fragments are limiting factors that are difficult to repair. Base saturation and pH H2O with liming, or addition of organics.
