Increasingly busy activity times have encouraged the increasing popularity of reservation methods for various services. As technology develops, various service reservations can be increasingly easily accessed via smartphone. Starting from ticket reservations, hotels, restaurants, including car servicing. However, there are still not many car service reservation applications that can accommodate various brands and types of workshops in Indonesia, even though data shows that the number of vehicles and workshops continues to increase every year. This opportunity was the background for the development of the Otoku Bengkel application. Otoku Bengkel is a car service reservation and workshop management application for workshop users. During its development, the development of Otoku interaction design has not followed certain rules. This opens up wide opportunities for improving the interaction design of the Otoku application. One of the things that needs to be considered in application development is interaction design analysis so that the designed application can be used well by users. The approach used in this design is User Centered Design (UCD), which is based on the ISO 9241-210:2019 standard. UCD is an iterative process where each phase focuses on user needs. The design stages carried out are understanding and determining the context of use, identifying user requirements, designing design solutions, and evaluating design solutions. The design and evaluation stages of design solutions were iterated twice. The final result of this research is a high fidelity prototype that is able to achieve the usability goals of effective to use, utility and easy to learn, as well as the user experience goal of helpfulness. As metrics for measuring the achievement of usability goals and user experience goals, the usability test, interview, Success Rate, Intrinsic Motivation Inventory (IMI), Single Ease Question (SEQ), and System Usability Scale (SUS) methods are used. Testing the second iteration of this research shows that the interaction design built is able to answer the usability goals and user experience goals that have been determined.
