<![CDATA[Background: Floods are hydrometeorological disasters that frequently occur in South Kalimantan, particularly in Banjar Regency, and can increase the risk of health problems such as skin diseases and digestive disorders. These conditions are associated with the practice of personal hygiene. Appropriate health education is needed to improve students’ knowledge of personal hygiene during floods. This study aimed to analyze the effectiveness of Japin Bakisah in improving knowledge of personal hygiene during floods among students at SMP Negeri 2 Martapura Timur. Methods: This study employed a quasi-experimental design using a pretest-posttest control group design approach. The study population consisted of 50 students, with a sample of 30 respondents selected using purposive sampling. All respondents received the same intervention and underwent pretest and posttest assessments. Data were collected by measuring knowledge of personal hygiene before and after the Japin Bakisah intervention. Data analysis was performed using a paired t-test. Results: The mean knowledge score before the intervention was 23.20 (SD = 1.400), while the mean score after the intervention was 23.10 (SD = 1.918). The Wilcoxon test results showed no significant difference between knowledge scores before and after the intervention (Z = −0.376; p = 0.707). Conclusion: Japin Bakisah did not demonstrate a significant effect on improving students’ knowledge of personal hygiene during floods. These findings indicate that further development of Japin Bakisah as a health education medium is needed to enhance its effectiveness in improving students’ knowledge.]]>
