Effectiveness of P3KU Mertion App on First Aid Drug Knowledge Among the Cadres of Nasyiatul 'Aisyiyah Gamping

Improving community-level knowledge on emergency drug use is essential, particularly in settings with limited access to trained healthcare professionals. This study evaluates the effectiveness of the P3KU Mertion mobile application in enhancing knowledge of simple emergency medications among young female health cadres affiliated with Nasyiatul 'Aisyiyah, Gamping Subdistrict, Special Region of Yogyakarta, Indonesia. A pre-post single-group design was employed, involving 42 participants aged 18—10 years. Participants completed a validated knowledge questionnaire before and after a 1-2-week intervention using the app, which included multimedia modules, quizzes, and reading materials. Data were analyzed using descriptive statistics and paired samples t-tests. Results indicated a significant improvement in total knowledge scores (mean difference: +19.5; p < 0.001), with the greatest gains observed in the domains of safety and contraindications, dosage knowledge, and drug function. These findings suggest that the P3KU Mertion app is an effective, accessible educational tool for non-professional health workers. Despite limitations such as a small sample size and lack of control group, the intervention demonstrates the potential of mobile health (mHealth) applications to support scalable, community-based health education. Future studies should assess long-term retention and explore broader implementation across diverse public health domains.
