Abstract: Student santri are required to fulfill dual roles as both university students and Islamic boarding school students, requiring educational guidance to strengthen their civic responsibility. This study aims to analyze the strategies for strengthening civic responsibility, the supporting and inhibiting factors, and the transformation of responsibility among student santri in a tahfidz-based Islamic boarding school. This study employed a qualitative approach with a case study design. Informants were selected using purposive sampling and consisted of the boarding school leader, administrators, senior santri, and junior santri. Data were collected through in-depth interviews, observations, and documentation, and analyzed using the Miles and Huberman interactive model with source and technique triangulation. The findings indicate that civic responsibility is strengthened through the habituation of daily activities, exemplary role modeling, mentoring, and the boarding school's disciplinary system. Supporting factors include a conducive environment, a culture of discipline, and social support, while inhibiting factors include role conflict, academic workload, physical fatigue, and unstable motivation. This study concludes that civic responsibility develops from compliance with rules into an internalized awareness manifested in the daily lives of student santri.Abstrak: Santri mahasiswa menghadapi tuntutan menjalankan peran sebagai mahasiswa sekaligus santri sehingga memerlukan pembinaan yang mampu memperkuat civic responsibility. Penelitian ini bertujuan menganalisis strategi penguatan civic responsibility, faktor pendukung dan penghambat, serta transformasi tanggung jawab santri mahasiswa di pesantren berbasis tahfidz. Penelitian menggunakan pendekatan kualitatif dengan desain studi kasus. Informan dipilih melalui purposive sampling yang terdiri atas pengasuh, pengurus, santri senior, dan santri junior. Data dikumpulkan melalui wawancara mendalam, observasi, dan dokumentasi, kemudian dianalisis menggunakan model interaktif Miles dan Huberman dengan triangulasi sumber dan teknik. Hasil penelitian menunjukkan bahwa penguatan civic responsibility dilakukan melalui pembiasaan aktivitas harian, keteladanan, pendampingan, serta sistem disiplin pesantren. Faktor pendukung meliputi lingkungan yang kondusif, budaya disiplin, dan dukungan sosial, sedangkan hambatan meliputi konflik peran, beban akademik, kelelahan fisik, serta motivasi yang belum stabil. Penelitian ini menyimpulkan bahwa civic responsibility berkembang dari kepatuhan terhadap aturan menjadi kesadaran yang terinternalisasi dan termanifestasi dalam kehidupan santri mahasiswa.
