U Usakti On APP is an academic information system application owned by Trisakti University. This application is available on the Android mobile platform and also on the website. Applications that run on the website involve users from all academic communities. The mobile application initially aims to make it easier for students to check grades and KRS. The condition of the user interface of the Usakti On App is still less informative and looks less attractive, the colors in the application lack contrast and are less comfortable for the eyes, so the information presented is not clear. Therefore, it is necessary to improve the flow of a system by applying the User Centered Design (UCD) method in designing the Usakti On App system. The prototype was created with Figma to produce a high fidelity design, that is, a design that is very similar to the final result. The results of the evaluation with SUS showed that the new system received an average data score of 80.86, which is good or "good" level.
