Redesign REDESIGNING THE UI/UX WEBSITE FOR THE INDUSTRIAL ENGINEERING DEPARTMENT AT MULAWARMAN UNIVERSITY USING DESIGN THINKING METHOD

Abstract

The industrial engineering department website of Mulawarman University faces challenges in disseminating
academic information due to inadequate maintenance. This research utilizes the design thinking method to
enhance the website's user interface and user experience (UI/UX) and evaluate its usability against the current
version. The decision to use design thinking is grounded in its established effectiveness in improving website
UI/UX. The study involves empathizing, defining, ideating, prototyping, and testing phases. User needs and
concerns were identified through interviews, observations, and tools such as affinity diagrams, user personas,
and user journey maps. Creative concepts were developed and organized using the priority matrix, sitemap, and
user flow. Wireframes and mockups facilitated pre-construction design visualization. The redesigned UI/UX
prototype resulted in a significantly improved user experience, as evidenced by the results of the user experience
questionnaire and system usability scale. The initial UEQ scores indicated low usability, with attractiveness at
0.85, perspicuity at 1.01, efficiency at 0.71, dependability at 0.76, stimulation at 0.41, and novelty at -0.18.
Following the redesign, scores notably increased, attractiveness at 2.06, perspicuity at 1.89, efficiency at 1.94,
dependability at 1.79, stimulation at 2.05, and novelty at 1.64. SUS testing revealed an average rise to 76 from
63 points, indicating enhanced user satisfaction, acceptance, and descriptive ratings. The website's grade
improved from C to B after the redesign. In conclusion, the UI/UX redesign successfully enhanced website
usability and user experience.
