<![CDATA[Reza Barbershop is a men's hair care service located in Padang Sambian, Denpasar, Bali, which still relies on a manual booking process. Customers are required to visit the barbershop directly or contact staff through personal phone numbers to make reservations, resulting in inefficient service, longer waiting times, and potential customer dissatisfaction. This study aims to develop a web-based booking system using the User Centered Design (UCD) approach to improve the booking process and enhance service quality. The development process consisted of identifying user requirements, designing the user interface, implementing the system using the Laravel framework and MySQL database, and evaluating the developed application. Functional testing was conducted using Black Box Testing, while usability evaluation was performed using the System Usability Scale (SUS) involving 30 respondents. The results indicate that all system functionalities operated successfully according to user requirements. Furthermore, the usability evaluation achieved an average SUS score of 82.67, corresponding to Grade A, an Excellent adjective rating, and an Acceptable level of usability. These findings demonstrate that the proposed web-based booking system provides a high level of usability and effectively supports customers in making online reservations while improving operational efficiency and service management at Reza Barbershop.]]>
