PERANCANGAN WEBSITE E-COMMERCE BOONABOO DENGAN PERBAIKAN PENGALAMAN PENGGUNA

ABSTRACT
An e-commerce website requires a well-designed User Interface (UI) and User Experience (UX) to ensure ease of use and provide a better user experience. The Boonaboo e-commerce website experienced several issues related to website performance, navigation, and interface design. The initial evaluation using the System usability scale (SUS) produced an average score of 47.75, indicating that the website had a low level of usability and still required improvements. This study aimed to redesign the User Interface (UI) and User Experience (UX) of the Boonaboo website using the User Centered Design (UCD) method. The redesigned website was evaluated using Google Lighthouse and the System usability scale (SUS) involving 20 respondents. The results showed that the Google Lighthouse Performance score increased from 41 to 84 on mobile devices and from 76 to 99 on desktop devices. Furthermore, the average SUS score increased from 47.75 to 87.75, changing the usability rating from Not Acceptable (Grade F – Poor) to Acceptable (Grade A – Excellent). These findings indicate that the redesign successfully improved website performance, usability, and user experience.
