The Islamic education curriculum in Indonesia tends to be partial and dichotomous. However, Muhammadiyah has reformed the holistic–integrative curriculum as a solution for the sustainability of education. This study aims to reveal a special curriculum reform in the holistic–integrative Muhammadiyah education system to solve the dichotomous problems and the inadequacy in the Islamic education curriculum in Indonesia. Furthermore, the study describes a specific curriculum model that includes all aspects of students’ personality and integrates science and technology with Islamic values. Data were collected from previous studies and special curriculum documents of Al-Islam, Kemuhammadiyahan and Arabic Language (ISMUBA).
