<![CDATA[The development of students' disciplined character is a significant challenge in the implementation of character education in vocational schools, where futsal extracurricular activities are seen as having the potential to instill these values through habituation and obedience. This descriptive qualitative study aims to describe the process of developing students' disciplined character through futsal extracurricular activities at SMK Baitul Izza Tulungagung and to identify supporting and inhibiting factors. Primary data collection was conducted through passive participant observation during training, in-depth semi-structured interviews with coaches, ten students, and student affairs, and documentation studies analyzed using the Miles and Huberman interactive model. The results show that futsal extracurricular activities effectively shape disciplined character through the habit of being on time, using training attributes according to regulations, complying with coach instructions, being a role model, and the application of educational sanctions and rewards. Positive impacts are seen in the increase in students' punctuality, responsibility, compliance with rules, teamwork, and sportsmanship at school. Supporting factors include high student interest, coach assertiveness, and school support, while inhibiting factors include inconsistency on the part of some students, limited facilities, and the influence of the social environment. The main conclusion confirms that futsal extracurricular activities have proven to be an effective vehicle for internalizing the values of discipline and forming positive character in vocational high school students in a sustainable manner.
