<![CDATA[The prevalence of overweight (14.8%) and obesity (24.4%) among adults in East Java Province reflects a diet that lacks diversity, nutritional balance, and safety (B2SA), despite the region's substantial local food potential. Batu City, whose horticultural sector contributes 14.50% of regional GDP and ranks as the second-largest economic sector, possesses such potential, yet its utilisation remains confined largely to raw-material production and distribution through long supply chains, which depresses farmers' economic value-added and disconnects producers from consumers. This study aims to formulate design criteria and concepts for an integrated Food Hub and food-education tourism facility in Mojorejo Village, Junrejo Sub-district, Batu City, using a socio-ecological approach that treats the food system as a unified interaction among humans, natural resources, and socio-economic activity. The research method applies empirical inquiry (observation, classification, induction, and verification) to two precedent studies—Pasar Induk Among Tani and Jawa Timur Park 2—combined with site analysis and a synthesis of six socio-ecological principles (social justice, locality, ecological integrity, resilience, and short supply chains). The resulting design, named Lumbung Land, integrates three primary zones (public, semi-public, and private) within a farm-and-granary-themed massing on an 8,387 m² site, with an estimated effective building area of 3,800–4,800 m². The design concept accommodates a transparent upstream-to-downstream (farm-to-table) food flow through short-supply-chain-based zoning, passive design responsive to the highland tropical climate, use of local materials, and inclusive spaces for people with disabilities and the elderly. This design is expected to serve as a model for healthy Food Hub development that strengthens agrarian identity, improves nutritional literacy, and supports the economic and ecological sustainability of Batu City.
