Evaluasi Usability pada Aplikasi BPOM Mobile menggunakan model People At the Center of Mobile Application Development (PACMAD)

The Food and Drug Monitoring Agency (BPOM) is a government institution that uses technological advancements in applications as a means to monitor public safety and security regarding products circulating in the market. Since its release, the BPOM Mobile application has received low ratings on Google Play and the Apple Store, along with many user complaints. Therefore, it is necessary to evaluate the usability of the BPOM Mobile application using the People At the Center of Mobile Application Development (PACMAD) model to improve the app's quality, making it more effective, efficient, and satisfying to use. PACMAD consists of seven aspects: Efficiency, Effectiveness, Learnability, Memorability, Errors, and Cognitive Load. The Likert scale was used to measure five aspects, while satisfaction was measured using the System Usability Scale (SUS), and cognitive load was assessed using NASA-TLX. The results from the Likert scale for each variable are as follows: Efficiency 71.2%, Effectiveness 74.1%, Learnability 70.4%, Memorability 70.9%, and Errors 71.4%, which are all categorized as “Good.” For the satisfaction variable, using SUS, the average score was 54.92, which falls under grade F or “OK,” indicating that while the overall result is acceptable, it is still low. For cognitive load, measured with NASA-TLX, the average score was 55.47, categorized as “Moderately High.”. This study is expected to serve as a reference for app developers to improve the system for better usability, ensuring that it is well-accepted by users. For futher research is suggested to explore other methods not used in this study for comparison with the results presented here
