Abstract

This study aims to evaluate the usability of the PRESISI POLRI application based on users' perceptions and experiences. A quantitative survey approach was employed using usability indicators and the System Usability Scale (SUS). Data were collected through an online questionnaire involving 384 users of the PRESISI POLRI application. Data analysis was conducted using SPSS version 22, including validity, reliability, classical assumption tests, and multiple linear regression to examine the relationships between learnability, efficiency, memorability, errors, and user satisfaction. Meanwhile, SUS was used to assess overall perceived usability. The results indicate that all four usability variables have positive and statistically significant associations with user satisfaction, with a coefficient of determination (R²) of 0.623. The average SUS score was 44.09, classified as Grade F, Poor, and Not Acceptable. These findings indicate a low level of perceived usability, highlighting the need for improvements in ease of use, efficiency, navigation, and error handling to enhance the user experience.
