Rendahnya pengetahuan dan sikap santri mengenai pencegahan gastritis masih menjadi tantangan dalam upaya pencegahan penyakit. Meskipun edukasi berbasis multimedia berpotensi meningkatkan efektivitas pembelajaran, bukti mengenai efektivitasnya terhadap pengetahuan dan sikap pencegahan gastritis pada santri masih terbatas. Oleh karena itu, penelitian ini bertujuan menganalisis efektivitas edukasi berbasis multimedia terhadap pengetahuan dan sikap pencegahan gastritis pada santri. Penelitian ini menggunakan desain quasi-experiment dengan non-equivalent control group pretest-posttest design. Sampel terdiri atas 146 santri berusia 12–15 tahun yang dipilih menggunakan purposive sampling. Kelompok intervensi memperoleh satu sesi edukasi berbasis multimedia menggunakan Presentasi slide, video edukasi, dan leaflet selama ±60 menit, sedangkan kelompok kontrol memperoleh edukasi yang sama setelah seluruh pengumpulan data selesai. Data dikumpulkan menggunakan kuesioner pengetahuan dan sikap yang diisi secara mandiri (self-report) serta telah diuji validitas dan reliabilitas. Analisis data menggunakan uji Wilcoxon Signed-Rank dan Mann–Whitney U. Hasil uji Wilcoxon menunjukkan peningkatan pengetahuan dan sikap yang bermakna pada kelompok intervensi (p

Low levels of knowledge and attitudes toward gastritis prevention among Islamic boarding school students remain a challenge to disease prevention efforts. Although multimedia-based education has the potential to enhance learning effectiveness, evidence of its effectiveness in improving knowledge and attitudes toward gastritis prevention in this population remains limited. Therefore, this study aimed to analyze the effectiveness of multimedia-based education on knowledge and attitudes toward gastritis prevention among Islamic boarding school students. This study employed a quasi-experimental design with a non-equivalent control group pretest–posttest design. A total of 146 students aged 12–15 years were selected using purposive sampling. The intervention group received a single 60-minute multimedia-based educational session using slide presentations, an educational video, and a leaflet, whereas the control group received the same education after data collection was completed. Data were collected using validated and reliable self-report questionnaires assessing knowledge and attitudes toward gastritis prevention. Data were analyzed using the Wilcoxon Signed-Rank and Mann–Whitney U tests. The Wilcoxon Signed-Rank test showed significant improvements in knowledge and attitudes in the intervention group (p < 0.001), while the Mann–Whitney U test indicated significant differences between the intervention and control groups (p < 0.001). Therefore, multimedia-based education was effective in improving knowledge and attitudes toward gastritis prevention among Islamic boarding school students and may be considered a health promotion strategy in Islamic boarding schools.
