The number of samples in this study is 97 responded, and used Probability Sampling with Stratified Random Sampling. Data analysis techniques using software MINITAB. This study collects data using the interview process and distributing questionnaires. From the interview results, it can be said that there are things that must be improved in iraise. Such as iraise often experiences errors when many are accessing. iraise must continuously be updated. From the evaluation, it can be stated that the user was less content with iraise on the format variables with valuation value 2.99, corresponding with value-3.92 value-value 3.06, content variable with value-3.16 value-and variable ease of use with value-3.26. This shows the user is less content with the Iraise.The academic information system of UIN Suska Riau, called Integrated Academic Information System (IRAISE), is a web-based information system built with a view to the organization of academic data.
