<![CDATA[Based on KPAI data for the 2016-2022 period and DIY Regional Police data for 2016-2021, juvenile delinquency cases have increased significantly, with the majority of perpetrators being students involved in smoking during school hours, bullying, truancy, and brawls. This phenomenon threatens the nation's future. This study aims to examine and analyze the relationship between self-concept, self-control, and religiosity—both partially and simultaneously—with juvenile delinquency among 11th-grade students in public vocational high schools across Kulon Progo Regency. This research employs a quantitative associative approach utilizing a questionnaire survey method via Google Forms. The sample consists of 326 students selected through random sampling from a total population of 2,163 eleventh-grade students across 8 state vocational schools. The findings indicate: first, there is a significant and negative relationship between self-concept and juvenile delinquency (r = -0.219). Second, a significant and negative relationship exists between self-control and juvenile delinquency (r = -0.155). Third, there is a significant and negative relationship between religiosity and juvenile delinquency (r = -0.277). Fourth, self-concept, self-control, and religiosity simultaneously have a significant effect on juvenile delinquency, with an R-squared value of 0.082 or 8.2%. In conclusion, these three independent variables account for 8.2% of the variance in juvenile delinquency, while the remaining 91.8% is influenced by other factors outside the scope of this study.]]>
