Insulation or separation between general knowledge and Islamic religious education curricula in formal educational institutions and the injustice of students getting the opportunity to study in schools under Dutch colonialism oriented towards a general knowledge curriculum became a deep concern by the KH. Ahmad Dahlan at that time. The implementation of his thoughts will be traced to current educational institutions, both in Indonesia and other parts of the world, such as Europe. Therefore, this research aims to elaborate on the character of the Scholar‟ 's thought, which combines general education with worldly insights in public schools and Islamic boarding schools based on the Qur'an and Sunnah, which are oriented towards the afterlife. The first step “Sang Ulama” took was to approach and collaborate with the management of Budi Utomo in Yogyakarta, which is close to government-owned schools. Furthermore, on the advice of Bung Tomo, KH. Ahmad Dahlan founded his school with Islamic nuances and broad insight, named Volks School Muhammadiyah Kauman in 1916 as the first native-owned public school in Indonesia. Currently, the implementation of this thought has developed in the curriculum of government-owned public educational institutions and Islamic religious education institutions without eliminating the existence of Islamic boarding schools. The thought of this curriculum character gets a special portion at all levels of education, be it elementary, middle school, or even higher education in Indonesia and globally, without any obstacles from the National curriculum.
