<![CDATA[The health of elementary school students forms the foundation for a healthy and productive generation. However, unhealthy dietary habits and unbalanced lifestyles can increase the risk of digestive tract disorders, which impact children's growth and development. This community service program aimed to enhance the knowledge of students at SD Negeri 066652 Medan regarding the importance of digestive health and the role of prebiotics and probiotics in supporting it. The activity took place on April 10, 2026, at SD Negeri 066652 Medan, North Sumatra, involving 40 students. The program utilized interactive seminars and workshops comprising material presentations, discussions, Q&A sessions, and interactive quizzes. The topics covered included the gut microbiome, factors influencing digestive health, and the benefits of consuming yogurt—a probiotic source containing Lactobacillus, Bifidobacterium, protein, calcium, vitamin D, and vitamin B12. Knowledge assessment was conducted via pre-tests (before the presentation) and post-tests (after the activity) using identical or equivalent questions. Evaluations also involved interactive quizzes and discussions with teachers regarding the activity's implementation and future program follow-ups. Results showed an increase in participant knowledge, evidenced by a rise in the proportion of students in the "good knowledge" category from 15% in the pre-test to 82% in the post-test—an increase of 67 percentage points. Meanwhile, the proportion of students with "poor knowledge" dropped from 45% to 0%, and those with "fair knowledge" decreased from 40% to 18%. These findings demonstrate that pharmaceutical education delivered through interactive seminars and workshops can improve students' understanding of digestive health and the benefits of prebiotics and probiotics. The program is expected to raise student awareness about maintaining digestive health and pave the way for future initiatives, such as education and training on probiotic beverage production for the surrounding community.]]>
