This study was conducted to analysis the integration of Islamic educational values within local wisdom through the cultural tradition of Mappanretasi, practiced by coastal communities in Tanah Bumbu regency, South Kalimantan. As a form of cultural expression and spiritual devotion, Mappanretasi reflects essential Islamic values such as gratitude to Allah, mutual cooperation (gotong royong), environmental awareness, and respect for religious and traditional leaders. Through a descriptive qualitative approach, it was found there are four Islamic values that contained in the Mappanretasi tradition, (1) gratitude to Allah SWT, (2) communal work and Togetherness, (3) Responsibility for the Environment, (4) Obedience and Respect for Leaders and Ulama. Based on the observation that the study highlights how these values can be incorporated into local wisdom-based education to strengthen character formation, moral values, and cultural identity among students. The findings suggest that Mappanretasi not only preserves local heritage but also serves as a contextual educational medium aligned with Islamic teachings. This reinforces the importance of culturally relevant education in shaping holistic learners grounded in both faith and tradition.
