Evaluation of the Usability of Online Learning Platforms Using the System Usability Scale Method and Nielsen Usability Attributes

Abstract

This study aims to evaluate the usability level of one of the online learning platforms widely used by high school students, including those in SMA, SMK, and MA levels. The evaluation was conducted using two approaches: the System Usability Scale (SUS) and Nielsen’s Attributes of Usability (NAU). Data were collected through questionnaires distributed to 115 active users of the platform. The results showed that the average SUS score was 75.5, which falls into the “Good” category (grade B), indicating that the platform has a good level of usability. Analysis of the five attributes of Nielsen’s Attributes of Usability learnability, efficiency, memorability, errors, and satisfaction showed that all attributes received average scores above 4.21 on the Likert scale, with learnability being the highest (4.386) and memorability the lowest (4.293). These findings suggest that the online learning platform is considered easy to use and provides a positive learning experience, although there is still room for improvement, especially in terms of memorability and usage efficiency.
