This study was motivated by the disconnect between the organizational structure of the administration and the effectiveness of enforcing discipline among students in the era of digital disruption. The main problem identified is the low level of systematic implementation of managerial functions, where supervision remains limited to formal administrative procedures and there is a lack of consistent role modeling by administrative staff. The objective of this study is to analyze the application of the POAC (Planning, Organizing, Actuating, Controlling) management functions as well as the strategic role of administrators as manager-murabbi in fostering student discipline at the Darul Ishlah Islamic Boarding School. The research method used is descriptive-analytical qualitative, employing data collection techniques through in-depth interviews, participatory observation, and documentation over a three-month period. The findings indicate that while planning and organizational structure are in place, the controlling function is the weakest link due to a lack of data-based evaluation and consistent follow-up on sanctions. The analysis concludes that student discipline is more effectively influenced by moral authority through the internalization of the values of muraqabah and amanah than by a purely regulatory approach. Concrete recommendations proposed include the standardization of digital-based standard operating procedures (SOPs) for transparency regarding disciplinary violations, as well as the regular conduct of transformative leadership training for administrators.
