Telkom Directorate of Digital Business prioritizes technology as a support in supporting company performance. In supporting the company's activities, Telkom DDB performs talent outsourcing or a labour recruitment system, one of which is for practical work activities. In practical work activities at Telkom the Digital Business Directorate, an information system design has been carried out to assist in managing practical work student activities. Because the information system design process is still at the design development stage, it is necessary to ensure that the planned design has gone through a testing process, one of which is the usability to obtain the best results. This study aims to improve usability evaluation of the system. A formative evaluation was conducted on 15 students as test participants and asked to complete the test task. In the practical work system testing, there are 6 tasks completed by the participants. Each data from the task is processed according to the parameters used, namely effectiveness, efficiency, satisfaction level and is equipped with eye tracking and retrospective thinking-aloud (RTA) measurements. The effectiveness parameter is measured using the success rate, efficiency is measured using the lostness, and user satisfaction is measured using the system usability scale (SUS) value. The results showed that prototype of the practical work information system of Telkom's Digital Business Directorate was not yet fully effective because task 2 had an effectiveness value of 33.33%. The Telkom DDB KP system is also not fully efficient because tasks 2 and 3 have lostness 0.580 and 0.420. The results of the average system usability scale (SUS) score of 62.5 indicate that the system needs to be improved. Error data, retrospective thinking aloud, and eye tracker are used to find out in detail the problematic task elements so that a proposed improvement design is made. There are 19 proposed improvements for prototype of the Telkom DDB practical work information system.
