This behavior has significant negative impacts on mental health, social relationships, and the overall learning climate at school. Social media, as the main platform for adolescent interaction, often serves as a medium for digital harassment, thus requiring appropriate educational interventions. One effort that can be implemented is the socialization of bullying prevention through social media. This study aims to examine the effectiveness of educational socialization on bullying prevention via social media in improving students’ knowledge and attitudes toward preventing such behavior. The research employed an experimental method with a pretest-posttest one group design. The subjects were 49 students from SMK Swasta Global Cendekia, with questionnaires measuring knowledge and attitudes toward bullying prevention. The paired t-test analysis showed a significant difference between pretest and posttest scores (t(46) = -2.278, p = 0.027), with higher mean scores in the posttest compared to the pretest. These findings demonstrate that bullying prevention socialization through social media is effective in enhancing students’ understanding and awareness of the dangers of bullying.
