Nutrition education is critical in increasing the consumption of vegetables and fruits among adolescents. This study aimed to assess the impact of nutrition education using Android applications on changes in knowledge and attitudes towards vegetable and fruit consumption of students at SMPN 8 Semarang. This study used a quasi-experimental design with pretest and posttest groups. Samples were selected, consisting of 40 adolescents divided into two groups: a treatment group and a control group. Data were collected through questionnaires on nutrition knowledge and SFFQ (Semi-Quantitative Food Frequency Questionnaire) forms, which were used to assess the level of consumption of vegetables and fruits. Data were analysed using the Wilcoxon test for the control group and the paired t-test for the experimental group. Results showed that the mean knowledge score in the treatment group increased significantly from 81.00 to 115.00 after the intervention (p < 0.001), whereas the control group's score only increased from 12.00 to 12.50 (p = 0.564). Among the motivated group, there was also an increase in vegetable consumption from 108.93 grams per day to 123.12 grams. However, the control group showed no significant change in fruit and vegetable consumption. Conclusion: The Android application serves as an effective medium for nutrition education, increasing knowledge and promoting dietary behavior changes towards consuming more vegetables and fruits among adolescents.
