Cases of child sexual abuse in Indonesia continue to increase each year. In the Special Region of Yogyakarta, Yogyakarta City ranks among the areas with the highest incidence. A preliminary study conducted at SD Negeri Dalem revealed that students had a low level of understanding about sexual abuse, with some having experienced it firsthand. One promising and age-appropriate intervention is the use of animated video media. To determine the effect of animation-based sex education on knowledge and self-awareness in preventing sexual harassment among students at SD Negeri Dalem Yogyakarta in 2025. This study employed a quantitative method with a pre-experimental one-group pre-test post-test design. A sample of 50 students from grades 3 to 6 was selected using proportionate stratified random sampling. The research instruments consisted of questionnaires measuring knowledge and self-awareness. Data were analyzed using univariate analysis and bivariate analysis with the Wilcoxon signed-rank test. The Wilcoxon test showed a significant effect on the improvement of knowledge (p-value = 0.012), indicating that the null hypothesis (Ho) was rejected and the alternative hypothesis (Ha) was accepted. However, there was no significant effect on self-awareness (p-value = 0.672), meaning the null hypothesis was accepted and the alternative hypothesis was rejected. The number of students in the “good” knowledge category increased from 10 students (20.0%) to 22 students (44.0%) after the intervention, while those in the “good” self-awareness category increased from 30 students (60.0%) to 34 students (68.0%). Animated video education is effective in increasing students' knowledge about the prevention of sexual harassment; however, it is not yet sufficient to significantly improve self-awareness. This indicates that enhancing self-awareness requires more in-depth, repeated, and interactive educational methods.
