This study aims to analyze the inculcation of Islamic worldview through extracurricular activities and hidden curriculum at Darunnajah Islamic Boarding School (Pondok Pesantren) in Jakarta. The Islamic worldview, rooted in tawhid and encompassing the dimensions of iman (faith), Islam (submission), and ihsan (excellence), is not solely cultivated through formal intracurricular channels but also through non-formal dimensions that are often more effective in shaping students' character. This research employs a qualitative approach with a case study method. Data were collected through in-depth interviews, participatory observation, and documentation. The findings reveal that Darunnajah integrates Islamic worldview inculcation through three complementary curriculum tracks: intracurricular, extracurricular, and co-curricular. In the extracurricular track, activities such as Islamic scouting, Islamic arts, debates and muhadarah (public speeches), Islamic-spirited sports, and student leadership through OSDN serve as media for the practical internalization of tawhid values. Meanwhile, the hidden curriculum operates through habituated practices—congregational prayers, Qur'anic recitation, classical Islamic text studies (kitab kuning), and community service—that holistically shape students' attitudes, habits, and worldview. The integration of intracurricular and extracurricular activities positions the pesantren as a total learning environment, effectively instilling an Islamic worldview. This research contributes to the development of an Islamic education model that integrates formal and non-formal dimensions as a comprehensive strategy for worldview inculcation.
