Comparison of Video and Leaflet Media on Chemical Laboratory Safety Knowledge Among Vocational High School Students in Serang

The likelihood of accidents occurring on the job is much greater in educational labs in comparison to industrial laboratories. In the context of vocational students, the purpose of this research is to evaluate the efficacy of video and leaflet media in terms of enhancing students' understanding of chemical laboratory safety guidelines. The methodology used in this investigation was a pre-experimental study that utilized a two-group pretest-posttest design. An overall sample that was split into two groups: one for video (30 students) and one for leaflet (30 students). In order to examine the data, the Paired Samples Test was used. According to the findings, the average knowledge score of the video groups improved from 54.59 (which is considered to be quite low) to 74.17 (which is considered to be excellent), with a gain of 19.58 points (p<0.001). There was a significant rise of 25.69 points (p,0.001) in the leaflet group's mean score, which went from 63.62 (moderate) to 89.31 (very excellent). Upon doing an investigation of effectiveness, it was determined that video media had a success rate of 74%, while leaflet media achieved a fantastic success rate of 89%. Before beginning their practicums, it is strongly suggested that students make it a habit to familiarize themselves with the safety laws that govern chemical laboratories.
