Analysis of Agricultural Land Capabilities in the Spatial Plan of the Berau District, Indonesia (2016 – 2036)

Abstract

An analysis of the carrying capacity of agricultural land needs to be carried out to determine the land's ability to provide food to meet the needs of the population in an area within a certain time.  Land capability is a component used to determine the suitability of land potential for land use. Land use that is not by its capabilities has the potential to experience land degradation.  The research aims to determine the condition of agricultural land specified in the Berau Regency Regional Spatial Plan based on land capacity.  The research was carried out in the Berau Regency area, East Kalimantan Province, especially in agricultural areas consisting of plantation areas, wetland agriculture, and dryland agriculture.  This research uses a spatial descriptive method, namely an approach used to describe and analyze phenomena related to a particular space or location. The research data used is secondary data obtained from local government agencies, data provider websites, and the Geospatial Information Agency (BIG). The data analysis used to determine land capability is carried out using Weight factor matching, namely determining the land capability class based on the heaviest class of parameters in each map unit and for land suitability analysis of the land capability class of agricultural areas based on suitability resulting from evaluations that refer to land characteristic criteria. The results of the research show that land capability classes are dominated by classes III of 200.611,42 hectares for use of 166.526,94 hectares of plantation land; wet land covering an area of ​​11.317,82 hectares and dry land covering an area of ​​22.746,66 hectares; and class IV land capacity of 181.071,29 hectares for plantation land use of 162.331,20 hectares; wet land covering an area of ​​3.699,70 hectares, and dry land covering an area of ​​15.040,39 hectares;  The total area of ​​land that is declared appropriate is 501.475.28 hectares (76.11%) and the area of ​​land that is temporarily declared non-compliant is 119.792.57 hectares (23.89%); and this non-conformity occurs on land with land capability classes V, VI, and VIII.
