Indonesia, a nation founded on the principles of unity in diversity, will commemorate its 80th year of independence in 2025. Despite the founders' lofty ideals, challenges persist, particularly in the realm of religious diversity. Issues such as intolerance, fundamentalism, radicalization, and the politicization of religion continue to hinder interreligious harmony, a crucial element for Indonesia's progress. This research delves into the role of peace education in promoting interreligious harmony within Indonesian higher education. Challenges such as religious intolerance, polarization, policy gaps, resistance to change, resource constraints, and youth aggression impede the effective implementation of peace education programs. To address these issues, this study will conduct a comparative analysis of peace education programs at Universitas Islam Negeri Sunan Kalijaga and Universitas Kristen Duta Wacana, two universities with distinct religious affiliations. By examining these case studies, the research aims to contribute to the development of more effective and sustainable peace education programs that emphasize religion's potential to foster peace in Indonesia.
