Brawijaya University Televisi or commonly abbreviated as UBTV is an official campus-based community television owned by Universitas Brawijaya Malang. To facilitate the dissemination of live broadcasts, UBTV creates a mobile application that can be used in all platforms. This mobile application has been created by the developer but has not yet been released and has never passed usability evaluation. So that the benefits of UBTV can be achieved, then by conducting usability evaluation can allow the user's goals to be as expected. This research uses 2 evaluation methods, namely heuristic evaluation and usability testing. Heuristic evaluation is used to explore problems based on 4 expert evaluators. From the heuristic evaluation it produces 20 problems consisting of 16 interface problems and 4 functional problems. After heuristic evaluation, then evaluation with usability testing using 3 aspects, namely learnability, efficiency and satisfaction. Usability testing evaluation is done twice, namely the old design and new design. From the old design to the new design experiencing an increase in the learnability aspect of 0.2, it is easier to use on new designs, the efficiency aspect is 61.7% and aspect satisfaction is 63.1%.
