Abstract

To achieve the vision of becoming the largest Electronic Publisher in Indonesia, UB Press released UB Bookstore Application. There are 5 processes observed: sign up and sign in process, profile editing process, category and book search process, and book details. Problems in applications that appear on the initial observation include unresponsive navigation, lack of detailed book information, lack of interest in application color, and difficult to finding book and menu navigation. Therefore, there are three basic guidelines used for repairing the application interface. Further, usability testing is done for initial and new design. ISO 9241-11 is used as a standard to measure usability metrics, including Effectiveness, efficiency and satisfaction metrics. The results of the Effectiveness metrics are divided into 3 aspects: Success with 40% improvement, Non Critical Error , and Critical Error which is decreased to 0%. After repairing the application interface, efficiency metric increased to 40% after the interface repair. In the aspect of satisfaction, the new interface design is in grade C and in the "Acceptable" category. The researcher also used a USE questionnaire that included four criterions. Each criterion has several statements given to the user to assess the usability level of the application. The result of usability score of this questionnaire before recommendation is 60,38% and after recommendation of new design is 79,70%.
