Redesign of a Laboratory Website Using User Centered Design Method and WEBUSE

Laboratory website is one of the main supporting facility in teaching and learning activities in a university. It contains information about laboratory works and events. Industrial Engineering program of Universitas Islam Indonesia currently have 11 educational websites which are accessed by students in daily routine. Innovation and Organization Development (IOD) is one laboratory that already implemented website technology to support its educational activity. Our preliminary study showed that website from IOD laboratory has the most interface problem compared to the other ones. This study aim to redesign the laboratory website using user centered design method based on three usability aspects that consist of effectivity, efficiency, and personal satisfactory. This study involved 30 participants which are categorized into three different level of experience in using the website, they are expert, intermediate, and beginners. Usability problem was identified using think-aloud evaluation method while those participants worked on representative task. Usability problems found on the website including font size that too small, not included university logo as an identity, not integrated to other laboratory websites, and used unattractive color and background. According to usability problem identification, the average of participant’s task completion rate is about 99.4 %, the obstacle was on finding business news and laboratory achievement task. Based on those results, then we redesigned the website using user centered design method that consists of 4 steps including analysis, synthesis using WEBUSE questionnaire, simulation, and evaluation. The results indicated that the usability level identified by WEBUSE questionnaire and usability problem found by interview can be used guideline to redesign website interface when using user-centered design method.
