<![CDATA[Background: Early adolescents are an age group that is vulnerable to sexual violence due to low knowledge of interpersonal boundaries. Data from the Magelang City Departement of Community Empowerment, Women, Child Protection, Population Control, and Family Planning 2024-2025 shows that there are 15 cases of sexual violence in adolescents aged 10-13 years who still have a low level of knowledge related to interpersonal boundaries. Efforts have been made by local agencies, including through outreach in schools and child protection campaigns. However, the weakness is that the programs provided are still general in nature and have not been integrated with interactive learning media.Methods: This study used a quantitative method with a pre-experimental design of the one group pretest-posttest type, as well as providing material related to understanding sexual violence prevention, program objectives, types of violence in the virtual and real worlds, and perpetrators of sexual violence. The sample amounted to 55 students in grades V and VI at SDN 1 Tidar, Magelang City, who were selected through the total sampling technique. The research instrument was in the form of a knowledge questionnaire, and data analysis using the Wilcoxon Signed Ranks test  with an alpha of 5% because the data is not normally distributed.Results: The results of the study showed a significant increase in knowledge after being given an intervention with Moksal media with a p-value = 0.000. A weakness of this study is the absence of a control group; however, the accuracy of this learning medium is guaranteed by providing material related to the prevention of sexual violence.Conclusion: Moksal learning media  is effective in increasing early adolescents' knowledge about sexual violence prevention ]]>
