Stunting remains a significant public health concern despite a decline in prevalence from 24.4% (2021) to 21.6% (2022), as reported by the Indonesian Nutrition Status Survey (SSGI). One strategy to address stunting is preventing anemia in adolescents. This study examines the effectiveness of a sweet potato leaf-based functional drink in preventing anemia among adolescents in the Nusaherang Health Center, Kuningan Regency, where sweet potato cultivation is abundant. A quasi-experimental pre-test and post-test control design was used, with stratified random sampling to select adolescents aged 10–19 years who met inclusion criteria. Hb levels were measured before and after the intervention. Results showed a median Hb level increase from 11 to 12, with a p-value 0.001, indicating a statistically significant improvement. These findings suggest that sweet potato leaf-based functional drinks are effective in preventing anemia, offering a cost-efficient and accessible intervention for adolescent health.

Child marriage is a pervasive global problem that has a significant impact on numerous countries across the globe. The objective of this study is to analyze the disparities in knowledge and attitudes among junior high school students in Cirebon in 2023, before and after an intervention using audiovisual media to raise awareness about the hazards of early marriage. This study utilized a quantitative approach and incorporated a quasi-experimental methodology known as the one-group pretest-posttest design. The sampling method was purposive sampling, specifically targeting kids from thirteen junior high schools in Cirebon, with a total of 204 participants. The study findings suggested a significant improvement in knowledge following the session. During the pretest, 87 students, accounting for 42.6% of the total, demonstrated good knowledge. This number increased to 137 students, or 67.2%, in posttest-1, and further to 197 students, equivalent to 96.6%, in posttest-2. In the pretest, 98 students (48%) demonstrated a positive attitude towards recognizing the risks of early marriage. This percentage climbed to 108 students (52.9%) in posttest-1 and further to 188 students (92.2%) in posttest-2. The statistical analysis using Cochran's test revealed a p-value of 0.00 for both knowledge and attitude, demonstrating substantial disparities in knowledge and attitudes before the intervention, after the first intervention, and after the second intervention about the hazards of early marriage.

 Early marriage is known as a global problem experienced in many countries. Based on Cirebon city marriage registration data for each sub-district, the number of marriages under 21 years old in 2020 is high (19.6%). Early marriage may affect the health condition of both the mother and the baby. Health promotion media is suitable to transfer any health information to adolescent groups. This study aimed to determine the effect of reproductive health education using video media on junior high school students' knowledge and attitudes about the dangers of early marriage in Cirebon City in 2022. The quasi-experimental design with one group pre-test and post-test methods was used. The sample was recruited using purposive sampling to the 102 people population of students in five schools around Cirebon City. Data were analyzed using univariate and bivariate analysis by the Mc-Nemar test. An increase in knowledge in the good category was obtained from 57.8% to 77.5% also in supportive attitude from 54.9% to 75.5% after the intervention. The results showed significant differences in knowledge (p-value = 0.001) and attitudes (p-value = 0.001) before and after the video media intervention. It is highly recommended to enter any material related to early marriage into the junior high school curriculum also extracurricular activities at school.
