Background: Children's snack habits in elementary school are often not supported by a proper understanding of healthy food choices, so they prefer foods high in sugar, salt, and fat. The lack of interesting, appropriate nutritional information for children leaves their knowledge of healthy snacks still very limited. To overcome this problem, the edutainment method that combines education and entertainment can be an effective solution. With fun ways like games or interactive stories, children can more easily understand the importance of choosing healthy snacks. This study aimed to determine the influence of edutainment on elementary school children's knowledge of selecting healthy snacks. Methods: This study used a pre-experiment research design with a one-group pretest-posttest design. This research was carried out on May 17-June 03, 2024, at SD Muhammadiyah 1 Palu in the working area of the Kamonji Health Center. The population of this study consists of all 3rd-grade students, totaling 20 participants. The sampling method uses total sampling. The questionnaire contains 10 statements, and the scale used is Guttman's. The edutainment method is presented as an animated video embedded in the game. An animated video containing a collection of images or cartoons, lasting 4 minutes 36 seconds, is provided on selecting healthy snacks, including definitions, functions, sources, impacts, and criteria for choosing healthy snacks. The analysis of this study uses the Wilcoxon test. Results: The results of the univariate analysis showed that pretest student knowledge was good at 5.0%, fair at 15.0%, and less than 80.0%. After the edutainment method was carried out, the students' knowledge increased to either 60.0% and 40.0% adequate. The edutainment intervention was implemented, with posttest results showing good knowledge at 60% and 40.0%. The Wilcoxon test was negative, rank 0, positive, rank 20, and ties 0 p-value was 0.001<0.05. Conclusion: The edutainment method increases students' knowledge about selecting healthy snacks at SD Muhammadiyah 1 Palu. It is hoped that homeroom teachers can motivate students to further improve the habit of choosing healthy snacks with more interesting learning methods, such as Edutainment, which is learning that is inserted with games to make the learning process more fun.
