Hubungan Tingkat Pengetahuan Pelajar Tentang Cedera Otak Sebelum Dan Sesudah Penyuluhan Di SMA Negeri 5 Mataram

Abstract

Traumatic brain injury (TBI) remains a serious public health problem among adolescents, particularly due to motorcycle-related traffic accidents. Limited knowledge regarding early recognition, first aid, and prevention of TBI may increase the risk of inappropriate responses after injury. This community engagement activity aimed to improve students’ knowledge about traumatic brain injury prevention and first aid through a structured health education program at SMA Negeri 5 Mataram. The activity was conducted using a one-group pretest–posttest design involving 100 students from grades X–XII. The intervention consisted of educational sessions covering brain anatomy, mechanisms of injury, warning signs, first aid management, and the importance of standard helmet use, supported by audiovisual media and interactive discussions. Knowledge was evaluated using a 15-item multiple-choice questionnaire administered before and after the intervention. The results showed an increase in the mean knowledge score from 70.2 ± 10.2 to 75.4 ± 8.6 among paired respondents (n=65), with a statistically significant improvement (Wilcoxon signed-rank test, p<0.001). The proportion of students with good knowledge increased from 56.8% to 82.4%. This activity demonstrated that school-based health education effectively improved students’ awareness and understanding of TBI prevention and management. Continuous and interactive educational programs are recommended to strengthen long-term safety behaviors among adolescents
