Arabica coffee land suitability with a parametric approach based on square root

Arabica coffee is one of the most popular drinks by people in various countries. Coffee production is able to become a source of state income, especially Arabica coffee which has good export competitiveness. Therefore, an assessment of the suitability of land, especially Arabica coffee, needs to be carried out to estimate the extent to which land in Bantaeng Regency is suitable for Arabica coffee plants. The method used in this land suitability assessment is square root. Determination of the research location point is based on land use, especially coffee plants. The results showed that the land suitability class at all profile observation points was N1 (not suitable at this time) with the factors of soil depth, soil pH, calcium carbonate and salinity. The limiting factor for soil depth is difficult to repair, while the soil pH which is so high due to the presence of calcium carbonate which is also high enough for Arabica coffee can be repaired by providing sulfur. Salinity improvement efforts can be made by reclamation.
