Penerapan Web Content Accessibility Guidelines dan Design Thinking dalam Perancangan UI/UX Aplikasi Ujian Online

Abstract

Abstract. The most significant change in education due to the pandemic is the implementation of
online evaluation methods. Online exams provide students with the flexibility to take tests from
any location. Although online examinations offer flexibility for learners to participate from any location, their implementation still faces various challenges, such as the potential for cheating, technical disruptions, and limited accessibility for users with diverse physical conditions and digital
competencies. These issues highlight the need for designing online examination interfaces that are
not only easy to use but also inclusive. This study aims to design the user interface and user experience by employing the design thinking approach and applying the Web Content Accessibility
Guidelines (WCAG) to enhance interface accessibility starting from the design phase. The WCAG
2.0 standard, developed by the W3C, is applied as a guideline for meeting accessibility requirements. The WCAG principles implemented include perceivability, operability, understandability,
and robustness. Usability testing on the prototype was conducted using the System Usability Scale
(SUS), scoring 69. This score indicates that the designed prototype falls into the "marginal high"
category within the acceptability range. Accessibility testing using Axe for Designers indicated that,
overall, the prototype met accessibility requirements. The results also show that integrating WCAG
2.0 principles during the design stage effectively enhances the accessibility of the user interface.
