<![CDATA[Discipline is an important character that supports the success of the learning process. Based on observations, documentation, and interviews with the Guidance and Counseling teacher at SMK Negeri 1 Ampek Angkek, violations of school regulations were still found, including lateness, inappropriate uniforms, lack of concentration during learning, and leaving the classroom during lessons. Some students were also unable to recognize their potential, manage emotions, determine educational and career goals, and take responsibility for their behavior. This study aimed to measure students' levels of self-awareness and discipline and analyze the effect of self-awareness on student discipline. This study employed a quantitative approach with an associative research design. The population consisted of 643 students, with a sample of 246 tenth- and eleventh-grade students selected through stratified random sampling. Data were collected using a Likert-scale questionnaire and analyzed through descriptive statistics, the Kolmogorov-Smirnov normality test, linearity test, and simple linear regression using IBM SPSS Statistics version 26. The results showed that students' self-awareness was in the moderate category (82 students, 33%), as was their discipline (125 students, 51%). The data were normally distributed with an Asymp. Sig. value of 0.090, and the relationship between variables was linear with a Deviation from Linearity value of 0.759. The F-test showed a significant effect, with Fcount of 6.223 > Ftable of 3.89 and a significance value of 0.003. The regression equation Y = 68.851 + 0.173X indicated a positive relationship, while an R Square value of 0.149 showed that self-awareness contributed 14.9% to student discipline.]]>
