This paper examines the adaptation of the DeLone and McLean information system success models that are commonly used in the university's information systems domain. The survey design model was used in this study with 29 structured questionnaire items through Google forms used to collect data from 98 respondents, they were students, lecturers, and administrative staff in the Master Program of Civil Engineering Universitas Lambung Mangkurat Banjarmasin Indonesia. Structural equation modeling is used to test construct models. The results of data analysis showed that the quality of the system affected the use (β = 0.61, p <0.001) and user satisfaction (β = 0.22, p <0.001). Information quality affects usage (β = 0.30, p <0.001) and user satisfaction (β = 0.29, p <0.001). Also, service quality affects usage (β = 0.28, p <0.001) and user satisfaction (β = 0.55, p <0.001). However, use did not affect user satisfaction (β = 0.00, p> 0.05) but influenced individual impact (β = 0.32, p <0.001) and organizational impact (β = 0.19, p <0.001). User satisfaction affects individual impacts (β = 0.28, p <0.001) and organizational impacts (β = 0.17, p <0.001). Individual impacts affect organizational impacts (β = 0.73, p <0.05). The quality of the system, the quality of information, and the impact of the individual are the determining factors for the success of the information system at the university so it is very important that the information system at the university is designed so that it is easy to use, flexible, and functional to meet its objectives.
