ANALISIS USABILITY PADA WEBSITE SKPI UMM MENGGUNAKAN METODE SYSTEM USABILITY SCALE DAN COGNITIVE WALKTHROUGH

Certificate of Diploma Companion (SKPI) or Diploma Supplement is an official document from universities that contains the academic achievements of graduates. Since period 4 in 2018, SKPI has become a requirement for graduation and graduation at UMM, with a minimum score of 350 points. SKPI points are obtained from various activities, including mandatory activities, organizations, and seminars, which students input through the skpi.umm.ac.id website. However, this website has uninformative navigation and minimal guidance, making it difficult for students to input points. In addition, the website has never been updated or measured for quality, even though website quality is important to ensure effectiveness and user satisfaction. A thorough evaluation with a structured method is needed to improve the quality of the UMM SKPI website. This research uses two methods, namely the System Usability Scale and Cognitive Walkthrough. Cognitive Walkthrough provides in-depth qualitative analysis by assessing how users complete specific tasks on the website, identifying usability issues is strengthened by the use of the system usability scale method in quantitative measurement of overall user perceptions and validation of findings generated from cognitive walkthrough. Researchers involved 131 respondents for the system usability scale method and 20 respondents on cognitive walkthrough testing. The results showed that the system usability scale value of the SKPI website was 40.45 while the cognitive walkthrough value was 93% in the aspect of task completion, 0.171 goals/second in the aspect of time completion and 13.75% in the aspect of error rate. The results state that the UMM SKPI website needs improvements to the guide on the main page, SKPI assessment description with a link to the guide, SKPI information page on the main menu, “Dashboard” icon on each page, hover effect, full explanation option, and delete button in strategic locations will improve efficiency and user experience.
