The Land Potential Index is one way to know the value of land potential. Land Potential has an important function in land cultivation and how to use it. Land use should be appropriate for the land potential. If the land potential is high, the yield is high otherwise if the land potention is low, the yield is low as well. Inappropriate land use causes damaged soil and land degradation. The goal of this study is to determine the distribution of the Land Potential Index on agricultural land use in Samarinda City. The research was conducted from December 2020 to March 2021 in Samarinda City. The method used in this research is scoring and overlay to the analysis of land potential index on agricultural land use in Samarinda City and the distribution of each class. This research used 5 parameters to arrange the land potential index, which are slope, lithology, soil, rainfall, and flood risk. The Land Potential Index in Samarinda City for the area of agricultural use has an area of 10,383.60 Ha of the total area based on urban spatial design pattern in 2014-2034. The results of land analysis obtained in the agricultural area obtained 3 classes, were as follows very low class, the low class, and medium class. Overall in the city of Samarinda the very low class has an area of 9,569.15 Ha or 13.10%, the low class has a total area of 60,050.15 Ha or about 81.46%, and the medium class has an area of 4,008.74 Ha or around 5.44%. After overlapping with agricultural areas obtained the very low class has an area of 1,284.82 Ha or about 12.37%, the low class has an area of 8,923.85 Ha or about 85.94%, and the medium class area was 174.94 Ha or 1.68%. The agricultural landuse in the Samarinda city yields positive results in every class. This is based on the assessment of land potential in general. These area, in particular, can be used due to limited land capacity.
