<![CDATA[The moral crisis among young people has made the integration of academic and Islamic curricula an important strategy for shaping students' religious character, especially in boarding school settings. This study aims to examine how such curricular integration is designed, implemented, and evaluated collaboratively at International Islamic Boarding School (IIBS) Al-Maahira. The study uses a qualitative approach with a case study method through interviews, observation, and documentation. The findings show that integration is carried out systemically through joint planning, learning practices that contain Islamic values, structured non-academic activities, and the school environment as a hidden curriculum. In conclusion, a holistically designed integrated curriculum makes a real contribution to the formation of students' religious character. The implications of these findings encourage the development of Islamic education curricula that are integrated conceptually and operationally in modern pesantren-based educational institutions. Keywords: curriculum integration, Islamic education, religious character, boarding school.
