Beda Keterampilan Cuci Tangan Dengan Edukasi Pemutaran Video Dan Demonstrasi Dalam Pencegahan Diare Di Pesantren Sulaimaniyah, Malang

Diarrhea remains a health concern in boarding-school settings. Preliminary secondary data indicated that 15 of 103 students (14.5%) reportedly experienced diarrhea each month over the preceding six months, while a preliminary survey identified complaints of diarrhea in 8 of 20 students (40%). This research aims to examine differences in handwashing skills after video screening and demonstration education at Sulaimaniyah Islamic Boarding School, Malang. The research method employs a quasi-experimental study used a non-equivalent groups design involving 48 male students allocated to a control group, video screening group, and demonstration group (n = 16 each). A 10-step observation checklist was used to assess pretest and posttest, then the data were analyzed using Wilcoxon signed-rank, Kruskal–Wallis, and Mann–Whitney tests. The research results show mean scores rose from 36.250 to 78.125 in the video group and from 41.250 to 96.250 in the demonstration group. Within-group improvements were significant (video p = 0.001; demonstration p < 0.001). Overall group differences were significant (p < 0.001), whereas the comparison between video and demonstration was not (p = 0.056). Video-based education and demonstration both improved students’ handwashing skills; this study did not establish a statistically significant difference between the two methods.
