This study aims to describe the implementation of religious activities, analyze their revitalization efforts in improving students' religious character, and identify supporting and inhibiting factors at SMKN 7 Kota Serang. SMKN 7 Kota Serang was established in 2013 in Cipocok Jaya District, Serang City, based on community initiative, and currently serves 323 students across 9 classes under the leadership of Dr. Hj. Sunariah, S.Ag., M.Pd.I. This study employed a qualitative case study approach. Data were collected through participatory observation, in-depth interviews with the school principal, three Islamic Religious Education teachers, and students, as well as documentation study. Data were analyzed using the interactive model of Miles, Huberman, and Saldana, and validity was tested through source and technique triangulation. The results show that: (1) SMKN 7 Kota Serang implements structured religious activities including congregational Dhuhr prayer, Quranic recitation (tadarus), rotating student short sermon (kultum), Islamic student organization (Rohis), and commemoration of Islamic holidays; (2) revitalization was carried out through Rohis strengthening, regularization of congregational prayer, rotating kultum programs, and tahfidz habituation, effectively increasing student participation and internalization of religious values; (3) supporting factors include the principal's visionary leadership with a strong Islamic education background, professionalism of PAI teachers, and strong community support, while inhibiting factors include limited student awareness, time constraints within the vocational school schedule, and social media influence
