Integration of local wisdom in tourism: a cultural studies perspective for sustainable development in Samosir

This study evaluates the depth of local wisdom integration in supporting sustainable tourism in Samosir Regency through diagnostic mapping across the attraction, accessibility, and amenity sectors. Using a qualitative-descriptive design, data were gathered from 14 key stakeholders representing government, private sectors, and communities, then analyzed through systematic reduction and axial coding. Results reveal an “integration paradox”; Batak Toba local wisdom is aesthetically accommodated in cultural attractions and architectural designs but remains absent as an operational principle in accessibility and environmental practices. This is evidenced by an “X” status regarding technical sustainability, such as the lack of low-emission transport and waste management systems aligned with traditional nature conservation values. The novelty of this research lies in the formulation of a systematic model mapping the “integration gap” between symbolic representation and functional sustainability. These findings confirm that without functional Triple Helix collaboration, local wisdom remains a mere visual commodity with no impact on ecosystem preservation. The study recommends a policy shift from cultural promotion to mandatory green infrastructure regulations and the revitalization of endangered heritage narratives. By providing specific operational indicators, this research offers a strategic roadmap for stakeholders to synchronize infrastructure development with traditional environmental ethics to ensure long-term tourism sustainability.
