There were 249 samples have been collected using proportional stratified random sampling while also taken gender into account as well as  faculty (engineering and non-engineering) within undergraduate degree. By using 7 Likert Scale, it shown that usability of 0.62, information quality of 0.82, and interaction of 0.88 with high reliability based-on Cronbach's Alpha have been identified. Moreover, usability of 0.75, information quality of 0.78, and interaction of 0,84 with high validity based-on KMO/Kaiser-Mayer-Olkin and Balettet's Test have been achieved. Statistical results of demographic analysis have shown that only gender and faculty parameters influenced web service quality perception. Female students are more interactive than male students and non-engineering students are more interactive than engineering students. Meanwhile, from Internet users' perspective, it is shown that student who own a computer experiences more benefit of using student digital locker than student who does not own a computer.
