Refunctionalization of Post-Mining Land According to Land Capability Classes in the Tapunggaya area, North Konawe

This study was conducted in the Tapunggaya area, Molawe district, North Konawe, Southeast Sulawesi. The study aims to classify post-nickel mining land capabilities and provide recommendations for land use after mining activities. The method used in this research is the matching technique, which involves aligning the classification system with the actual field conditions. Several parameters for land capability classification were considered, including soil texture, effective soil depth, surface slope, soil drainage, erosion, permeability, rocks and gravel, and susceptibility to flooding or inundation. The results of the matching process revealed varying land capability levels. Three land capability classes were identified in the study area: class IV, covering 3.11 hectares; class VI, covering 2.54 hectares; and class VII, covering 9.14 hectares. Based on land capability classifications and the corresponding land use recommendations, the recommended use for class IV land is forest, which can be designated as a nature reserve or for limited production. Grazing land is divided into limited, moderate, and intensive grazing, while agricultural use is restricted and difficult to implement. The recommendation for class VI land is limited to forestry and grazing. Likewise, class VII land is only suitable for forest and limited grazing.
