<![CDATA[Manggis Gadungan Nature Reserve (NR) is a nature conservation area that plays a vital role in protecting biodiversity, as a water catchment area, and a life support system. The natural ecosystem in Manggis Gadungan NR has become increasingly important to preserve and defend since it was designated as a Pusat Ficus Nasional (PFN) in 2022. The balance of the ecosystem in Manggis Gadungan NR, with its various essential functions, must be maintained with the support of its buffer zone. Therefore, optimal management is not only for the Manggis Gadungan NR area but also for its buffer zone. A land-use inventory study can serve as the basis for sustainable management planning. Thus, this study aims to determine the land use inventory in the Manggis village and Manggis Gadungan NR as a basis for sustainable management planning. This study uses the Manggis Gadungan Nature Reserve as the study area, with spatial analysis and literature review to determine the land-use percentages in the Manggis Village and Manggis Gadungan NR, as a basis for sustainable environmental resource management. The study found five land-use types in the Manggis Village and Manggis Gadungan NR: production forests, settlements, rice fields, yards, and cultivated land. The most extensive land use is rice fields, covering 44 percent of the total area of 311.83 Ha, and the smallest is settlements. The land-use variations in the Manggis Village and Manggis Gadungan NR can be used to develop sustainable management plans that incorporate agroforestry, farmer groups, and reforestation models, and to assist villages in supporting environmental, social, and economic sustainability]]>
