<![CDATA[ABSTRACT The strengthening of religious character in elementary school students serves as a fundamental pillar for developing personalities oriented toward moral and spiritual values amidst the challenges of social degradation. This study aims to analyze indepth the implementation, dynamics, and impact of a school culturebased religious character-building program at SDN 1 Rowoharjo. Utilizing a qualitative approach with a descriptive design, the research subjects included the principal, teachers, and students. Data were collected through participant observation, semi-structured interviews, and documentation, then analyzed using the Miles and Huberman interactive model, involving data reduction, display, and conclusion drawing. The results indicate that the program is implemented systematically through strategic leadership policies, teacher role modeling, and routine activities such as congregational Dhuha prayer, morning prayers, Asmaul Husna recitation, and weekly tahlil. The implementation has a positive impact on improving students' discipline, responsibility, sincerity, and independent worship awareness. In conclusion, the internalization of religious character is effective when supported by teacher exemplary, program consistency, and a conducive religious school culture. This model at SDN 1 Rowoharjo holds significant potential for replication as a best practice in elementary school character education.
