Indonesia ranks second globally in natural disaster risk, underscoring the urgency of strengthening emergency preparedness. Generation Z, representing 28% of the population, plays a strategic role due to its digital fluency and entry into the workforce. This study assessed the disaster preparedness of Generation Z students using a modified Disaster Preparedness Evaluation Tool (DPET). A cross-sectional survey was conducted among 445 respondents aged 21–25 years. Data were collected through an online questionnaire covering demographics, knowledge, skills, and preparedness. Descriptive statistics, independent t-tests, one-way ANOVA, Pearson correlation, and multiple linear regression were used for analysis. Knowledge (M = 4.87), skills (M = 4.74), and preparedness (M = 4.65) were in the moderate range (scale 1–6). Prior disaster training, university region, and frequency of social media use significantly influenced preparedness (p < 0.05). Strong positive correlations were found between knowledge, skills, and preparedness (r = 0.77–0.82). Regression analysis identified skills, prior training, and knowledge as significant predictors, with skills being the most influential. The findings highlight the need to integrate structured disaster education, simulations, and digital interventions into higher education curricula. Enhancing experiential learning is critical to bridging the gap between digital awareness and real-world emergency response among youth in disaster-prone regions.
