Land suitability evaluation is crucial for sustainable plantation development, particularly in transmigration areas designated as emerging regional economic growth centers. These areas often exhibit heterogeneous land characteristics and management constraints that may limit agricultural productivity. This study assessed the actual and potential land suitability of three major plantation commodities: coffee, oil palm and rubber in the Padang Ulak Tanding Transmigration Area, Bengkulu Province, Indonesia. The study was conducted from August to December 2025 using an integrated approach combining field surveys, soil laboratory analyses and geographic information system (GIS) techniques. Land suitability classification followed the FAO framework adapted to the Indonesian Land Suitability Assessment System. Under actual conditions, most land units were classified as marginally suitable (S3), primarily due to shallow soil depth, acidic soil pH and steep slopes. The application of feasible land improvement measures, particularly soil fertility management and erosion control, improved land suitability to moderately suitable (S2) in most areas, although physical limitations remained in certain locations. These findings highlight the importance of site-specific land management and provide a scientific basis for sustainable plantation development in transmigration areas supporting regional economic growth.
