Gastritis can become a peptic ulcer, which eventually causes impacts such as bleeding, peritonitis, or even death. The survey results at SMP N 1 Liwa found that 61% of students did not know a good diet to prevent gastritis. Prevention efforts are carried out by increasing a person's knowledge, attitude, and diet through health promotion efforts, one of which uses intelligence wheel media (Roked). The purpose of this study was to determine the effect of health promotion using the wheel of intelligence (Roked) on knowledge, attitudes, and diet to prevent gastritis at SMP N 1 Liwa. This study is a quantitative study that uses the Quasy experiment method with a one group pretest-postest research design with control group. Intervention in the form of providing health promotion using intelligence wheel media (Roked).
