Student satisfaction surveys on the services provided by universities are one of the evaluation efforts aimed at maintaining and improving the quality of services for students. The survey questionnaire is developed using the Servqual method, which includes five dimensions of quality: Tangibility, Empathy, Responsiveness, Reliability, and Assurance. The questionnaire consists of 36 questions with a Likert scale and has undergone validity and reliability tests. After the instrument was used several times, some students expressed that the questions in the questionnaire were repetitive. Additionally, most students provided the same answers to all the questions. These two factors indicate the potential for bias in the survey data obtained. Therefore, efforts are needed to improve the existing instrument. The improvement of the instrument is conducted using factor analysis. The dataset used in this analysis consists of 36 initial variables and 400 samples. The implementation of factor analysis reduces the initial 36 variables into 5 main factors.
