This research examines the legal framework governing the protection of traditional culinary heritage in the context of sustainable gastronomy tourism development in Indonesia, with the aim of proposing a comprehensive normative model that integrates intellectual property law, cultural heritage law, and sustainable tourism governance. A normative juridical methodology is employed, encompassing three complementary approaches: statutory analysis, conceptual analysis, and comparative legal analysis across four jurisdictions (Indonesia, EU, Republic of Korea, and Peru). Existing legal instruments including Law No. 28/2014 on Copyright, Law No. 20/2016 on Trademarks and Geographical Indications, Law No. 5/2017 on Cultural Advancement, the UNESCO Convention (2003), and the WIPO Treaty on Traditional Knowledge (2024) constitute foundational but incomplete protective mechanisms. Four principal legal challenges are identified: definitional ambiguity, registration barriers, enforcement deficits, and the tension between protection and accessibility. A five-pillar normative framework is proposed, encompassing legislative consolidation, institutional capacity development, enforcement strengthening, benefit-sharing mechanisms, and international diplomatic engagement, providing a policy roadmap for Indonesia to achieve world-class protection of its traditional culinary heritage.
