Usability Evaluation and Design of Student Information System Prototype to Increase Student's Satisfaction (Case Study: X University)

A preliminary survey that was conducted to students of the Student Information System (SIS) at X University showed that the satisfaction level SIS was low. The main purpose of this study is to increase the student's satisfaction level by evaluating the usability of SIS. An experiment was conducted to thirty students of X University, categorized as an expert user (age 17 to 23), according to the usability testing method. The effectiveness, efficiency, and satisfaction of SIS are then measured by the Task Successful Rate, Mouse-Clicking, and System Usability Scale (SUS) scores. During the experiment, the participants were given several scenarios. The result proved that the SIS did not work well enough to satisfy the students/participants and improvements needed to be tested on the same participants. The testing process conducted using a prototype that was designed with HHS Usability Guideline. Through the usability testing, it was obtained that the effectiveness managed to increase from 58% to 85%, efficiency increased from 66% to 92%, and satisfaction scores increased from 53,83 to 70,67. Specific matters that influence the subjectivity of usability testing are noted and analyzed so that this study can be used as a practice for further study of usability evaluation in a similar student information system.
