Evaluation of the results of the development of a standard time calculation system which has been applied for approximately 1 semester (6 months) is done by using Webqual instruments where there are 3 parts of testing, namely usability quality, information quality and interaction quality. This assessment instrument emphasizes the assessment of information systems based on the perspective of the last user. As for the results of the validity of the Pearson Correlation score and by observing the score of Corrected Item - Total Correlation which is above 0.6 or equal to 0.6 and the reliability test results has obtained the score of chronbach's alpha above 0.60. And the results of the hypothesis for the variable usability quality is 0.700, which means that Usability Quality (X1) has a close relationship or influence on Overall Impression (Y), the results of the variable Quality Information hypothesis (X2) correlation coefficient 0.715 which means that the assessment has a relationship or close influence on Overall Impression (Y), and the results of the hypothesis variable Interaction Quality (X3) correlation coefficient 0.813 which means that the assessment has a close relationship or influence on Overall Impression (Y).
