This research project explores how the Tidung tribe's culture strengthens national identity in the Indonesia-Malaysia border region on Sebatik Island, an island off the coast of Borneo whose administration is split between Indonesia and Malaysia. Using a qualitative approach, the research analyses how the Tidung culture is preserved through customs, traditional games, and traditional cuisine. Primary data were collected from Tidung community leaders and academics, while secondary data were gathered from cultural documents. The research identified twelve cultural values embedded in the Tidung tribe's customs, traditional games, and traditional cuisine. These values are: religious, mutual cooperation, togetherness, independence, agility, integrity, courage, justice, permanence, firmness, simplicity, and fortitude. These values can strengthen national identity. Additionally, cultural preservation efforts were identified through the Iraw Festival and indigenous community programs. These values and efforts serve to strengthen national identity in the Indonesia-Malaysia border region and preserve the culture of the Tidung tribe.
