Child marriage is a form of violation of human rights. Child marriage remains a significant global issue, especially in Indonesia. Bengkulu Province is among the top 10 highest child marriages in Indonesia. Rolling ball is an interactive, interesting, and fun learning medium containing material about child marriage. This study aimed to determine the influence of rolling ball media on the knowledge of child marriage among adolescents in Bengkulu City and Bandung City, Indonesia. This study used an experimental design with a Randomized Controlled Trial (RCT) involving 120 adolescent girls who were divided into two groups (60 participants each). The variables studied were girls’ knowledge. Sampling was performed using block randomization. Data were analyzed using the Wilcoxon test. The respondents in the treatment group received education on rolling ball media for 30 minutes. The control group engaged with the disc as the learning medium for 30 minutes. Knowledge evaluation was conducted both before the start of learning and after one week. The research instrument utilized a questionnaire. The results of the analysis showed that the average knowledge score after intervention increased to 86.50, with a p-value of 0 (Wilcoxon signed rank test), while the average knowledge score in the control group increased to 77.42 with a p-value of 0.024. The results of the Mann-Whitney test showed a p-value of 0.000 ≤ 0.05. There was a significant difference in the effectiveness of rolling balls on knowledge about the impact of child marriage on adolescents. Health promotion activities are expected to use rolling ball media as an alternative health promotion medium to increase adolescent knowledge about the impact of child marriage and reduce the number of child marriages, with the hope of increasing the maturity of the age of marriage.
