Evaluation of IBSI Education System Use ISO/IEC 9126 Quality Model: How is the Quality?

The purpose of this study was to measure the quality of the IBSI Education System called SIWESI. Measurements will be carried out using ISO 9126 with the characteristics of functionality, usability, efficiency, reliability, and portability. Based on the test results from two perspectives including technical and user, SIWESI has good to very good quality. In terms of functionality, 95% of SIWESI's menus function properly. In terms of efficiency, the quality is good with the score of 100 for the desktop version and 99 for the mobile version. In the reliability characteristics, it can be stated that the more virtual users, the more the number of successful request processes will increase the resulting load time. Likewise with the results of Peak RPS, the more virtual users, the better the value. Meanwhile, for AVG Response Time, the more virtual users, the smaller the value. Technically, both from the browser and device side, SIWESI is accessible and works well. Based on the user's perspective, the quality of SIWESI is very good with a score of 84.66%.
