Abstract

Banyumanik is an area that has been geomorphologically shaped by the solutional process of karst rock, and it features various land uses. Improper land management based on these characteristics can lead to land degradation, primarily through erosion and sedimentation. This study aims to assess the current land uses, analyze land reserves and capabilities, and provide recommendations for land use aligned with these capabilities and reserves. The research employs survey techniques and map overlay using ArcGIS software. Sampling points were determined through random sampling. Analysis of land capability and suitability utilized the guidelines from the Indonesian Minister of Environment Regulation Number 17 of 2009. The analysis revealed five types of land use in Banyumanik, covering a total area of 177.22 hectares. The land capability was classified into three categories: Forest (Class V), Residence (Class I), Rained Rice (Class III), Field Land (Class V), and Shrub (Class III). Based on this classification, the use of Forest Land, Residence, Rained Rice, and Shrub is appropriate. However, the use of Field Land is deemed unsuitable as it falls under Class V. To improve land usage in Banyumanik, Field Land should be integrated with tree species, such as Teak (Tectona grandis), within an agroforestry system.
