Abstract

Schools in Indonesia face the challenge of low student knowledge and preparedness for tornado mitigation, a common hydrometeorological disaster that can threaten safety due to a lack of systematic disaster education. This study aims to determine the effectiveness of natural disaster mitigation education on tornadoes for ninth-grade students at SMPN 2 Pancur Batu. This study used a quantitative method with a one-group pretest-posttest pre-experimental design. The population in this study was all ninth-grade students at SMPN 2 Pancur Batu. The intervention involved 57 students in December 2025, with interactive counseling using visual media, discussions, and a three-point Likert scale pretest and posttest questionnaire to measure students' knowledge improvement. The results showed a significant increase in knowledge, with an average pretest score of 31.60 (SD=4.088) increasing to a posttest score of 32.65 (SD=4.104). Statistical test results showed a significant difference between the pretest and posttest scores (t=-3.711, df=56, p= 0.001), indicating that the education provided had a real effect on increasing students' knowledge. The effect size (Cohen's d = 0.492) indicates that the effect of the education was moderate, meaning that this intervention was quite effective in increasing students' knowledge in building awareness of natural disasters for reducing more dangerous risks after a disaster.
