This study examines the transformation of the Serak Gulo tradition from a cultural practice of the Indian-Muslim community in Pasa Gadang Village into an intangible cultural heritage (Intangible Cultural Heritage) nationally recognized by the Ministry of Education, Culture, Research, and Technology. The Serak Gulo tradition, held every 1st Jumadil Akhir, is a form of social and religious charity that has been practiced for over a century and has become a symbol of tolerance, togetherness, and pluralism in the Padang City community. This study used qualitative methods with a historical and cultural anthropological approach. Data sources were obtained through interviews with cultural practitioners, community leaders, traditional archives, and documentation from relevant agencies. The study covered the period 2019 to 2024, encompassing the application, verification, and designation process, and post-designation of the Serak Gulo tradition as an Indonesian Intangible Cultural Heritage. The results show that the transformation of Serak Gulo involved local actors, such as the Muhammadan Mosque community, the Padang City Cultural Office, the West Sumatra Cultural Values ​​Preservation Center, and relevant ministries involved in advocacy, documentation, and cultural promotion. Despite being designated a World Heritage Site (WBTb) in 2023, preservation challenges remain, including the regeneration of actors, pressures to modernize the old city area, and a lack of preservation funding. This research underscores the importance of ongoing collaboration among stakeholders to ensure the authentic and adaptive sustainability of intangible cultural heritage.
