Abstract

Evolution is a web application for collecting the Evidence report. This application is used regularly every quarter of the year. The main purpose is as a repository of evidence control that can be used at any time for audit purposes. Evolution Web Application will be utilized as a research object because there are problems with the user interface design and did not meet the concept of usability. To validate the Evolution Web Application User Interface Design problem and the improvements that will be applied according to user needs. User interview is conducted using Focus Group Discussion (FGD) with Evolution web Application users. The purposes of Focus Group Discussion (FGD) are to find problems in the user interface and expectations to achieve user goals for user interface design improvement. The interview results show that the current User Interface design has significant flaws. To improve the usability of the Evolution Web Application, a method known as User-centered Design (UCD) is used for improving the User Interface design of the Evolution Web Application. The evaluation after design improvement is carried out by using a Heuristic Evaluation involving 3 experts to review the usability of the design improvement result. Heuristic Evaluation produces answers from 3 experts with a severity value not more than a severity value of 2, which indicates a severity status of 2 is a Minor usability problem or fixing should be given low priority.

Abstract

The pandemic of COVID-19 resulted in the physical shutdown which has now transformed education into an exclusive "online learning" model. Zoom is being used to evaluate the perceived usability as the reference platform. The students find it less collaborative, less interactive, boring, and less collaborative. From this perspective, the Usability of the current online learning platforms is an important factor, particularly because no physical classes are present. The User-Centered Design (UCD) approach was chosen for this study and using the Usability Scale (SUS) method to evaluate the interface. The objective of this study is to analyze user experience, design solutions and evaluate user interfaces that can meet user needs. A pre-survey to evaluate the difficulties of the Zoom application based on user experience, and a post-survey to see if the upgraded design can help the students using the Zoom application for online learning. Then, use the System Usability Scale (SUS) questionnaire approach to measure the system's usability. After the UCD approach was completed, the researcher did a follow-up survey. The results showed that SUS ratings went up to 85.12. As a result, the previously low acceptability ranges have been raised to acceptable. Additionally, the grade scale has been reclassified B. The Zoom program now has more features and is easier to use, and fulfills the students' needs.
