Aims: Cardiac arrest is a sudden cessation of heart function and results in death if not immediately assisted with Cardiac Pulmonary Resuscitation (CPR). Chances of survival increase if immediately assisted CPR by people around or bystanders. There is a need to increase the quantity and quality of CPR bystanders through CPR education and training using application media that can be used anytime and anywhere. This study was done to determine the effect of CPR training using the SI-Hajar app on the knowledge and skills of teenagers about CPR. Materials & Methods: This study used a quasi-experimental design with a pre-and post-test approach to CPR training using the Si-Hajar app. Samples were taken by purposive sampling from ۴۰ teenagers in Lubuklinggau City Juni in December ۲۰۲۱. CPR knowledge was measured from knowledge about out-of-hospital hospital cardiac arrest (OHCA), which was measured using a questionnaire. Skill was measured by how the subject performed CPR using a CPR standard checklist regarding operating procedures. Findings: After the implementation of the Si-Hajar app, we found a statistically significant difference in knowledge and skill scores between the Si-Hajar and control (P<۰.۰۰۱ for both) groups. There was a correlation between group intervention and knowledge (p=۰.۰۰۱), but there was no correlation between knowledge and the history of cardiac arrest (p=۰.۰۷۶۱) and willingness to perform CPR (p=۰.۰۵۸۵). Regarding the CPR skill, there was a correlation between group intervention and skill (p=۰.۰۰۱), but there was no correlation between skill and the history of cardiac arrest and willingness to perform CPR. Conclusion: Using the Si-Hajar app has a significant effect on the knowledge and skills of teenagers in OHCA knowledge and CPR management.
