<![CDATA[Objective: Analyze the process of cultural and religious acculturation in the Nyambai Tradition of the Ranau community and its contribution to the achievement of the SDGs. The focus of the study includes the transformation of performances, rhymes, cultural symbols, and social interactions. Theoretical framework: The research uses the theory of cultural acculturation, interpretive anthropology, habitus theory, and the concept of Islamic living. This framework describes the integration of Islamic values into the local culture without losing its original character. Literature review: Previous studies have shown adaptations between Islam and local cultures in various community traditions. However, studies linking cultural-religious acculturation to the achievement of the SDGs are still limited. Method: The research applied an ethnographic qualitative approach through participatory observation, in-depth interviews, cultural documentation, and analysis of Nyambai rhymes. The data were analyzed interactively to find patterns of cultural transformation and Islamic values. Results: The Nyambai tradition undergoes selective acculturation, which is reflected in performance ethics, rhyming language, cultural symbols, and social interaction. Islamic values are integrated without eliminating the local cultural identity of the Ranau people. Implications: The Nyambai tradition supports culture-based education (SDG 4), gender ethics (SDG 5), cultural preservation (SDG 11), and social cohesion (SDG 16). These findings suggest that local traditions can be instruments of sustainable development. Novelty: This research offers a conceptual model of "cultural acculturation based on Islamic values for sustainable development (SDGs)". This model integrates cultural preservation, Islamic values, and sustainable development goals in a single analytical framework.]]>
