Abstract

ITENAS e-learning has problems such as the flow of access to complex features, and the color of the display and buttons that overlap with the background color. The design of the web interface in this study uses the WCAG 2.0 standard. With the success points of Criterion 1.4.11 Non-text Contrast in the Produce Design Solution stage in the User-Centered Design method. The results of the WCAG 2.0 test show the highest contrast ratio of 15.16:1 which has met the required contrast ratio, the criteria are successfully applied. In the design evaluation stage, this study used SUS to test the usability of the prototype. User experience testing in this study uses UEQ. The results of the evaluation of the usability of the interface with SUS in the initial test resulted in a score of 38.93 which was in grade F or bad to grade B with a score of 74.38 or good after the redesign process. The results of user experience testing with UEQ obtained an average Efficiency scale of 1.875. The Attractiveness scale is 1.667, the Clarity scale is 1.750, the Accuracy scale is 1.375, the Stimulation scale is 1.525, the last is the Novelty scale of 1.350 according to the UEQ average scale which is at a positive level. From the results of the two SUS and UEQ tests, the Usability aspect and the User Experience aspect of the Itenas e-learning web can be said to have improved.
