The decline in the quality of land and the environment is closely related to the increase in changes in land use to settlements as well as to agricultural land that is not in accordance with the spatial layout and function of an area. The purpose of this study is to analyze the suitability of land spatial plans based on the function of the area and analyze the suitability of land use to the function of the area. The method used is the scoring method by assigning a value to the nature of the parameters used in the analysis. The analysis used is Overlay where, the three maps that have been obtained using predetermined criteria are overlapped (overlay), so that the score value of the land unit map is then classified into areas with certain functions. Based on the results of the analysis, the watershed has 3 directions for the function of the area, namely the direction of the protected area function having an area of 17,876.01 ha, the buffer area having an area of 4,599.92 ha and the area for cultivation of seasonal crops and settlements having an area of 839.70 ha.
