<![CDATA[This study aims to explore the integration of sustainable education in indigenous communities in East Kalimantan, known for their rich culture and local wisdom. Indigenous groups such as the Dayak and Kutai possess traditional practices aligned with sustainability principles, yet these are not well accommodated in formal education. This study employed a qualitative case study approach involving customary leaders, teachers, and educational stakeholders. The findings reveal that sustainable education incorporating local values enhances the relevance of learning, community participation, and environmental preservation. Indigenous institutions play a vital role in developing culturally based curricula and addressing both social and ecological issues. Government support and regulation are also crucial through inclusive policies and recognition of customary law. This study concludes that synergy between communities, educational institutions, and the government forms the foundation for a sustainable education system rooted in local wisdom and responsive to future development challenges.]]>
