Abstract

Measurement of student satisfaction aims to maintain the sustainability of the implementation of the quality assurance system at the Bali State Polytechnic (PNB) and to obtain feedback related to continuous improvement efforts. The results are an evaluation material for the improvement and improvement of the teaching and learning process in PNB and to determine the quality of services that have been provided. The method that can be applied to determine student satisfaction has a positive, negative or neutral perception is to use a machine learning algorithm, namely Term Frequency-Inverse Document Frequency (TF-IDF) with classifier linear regression and logistic regression. The results of this study indicate that students’ perceptions are classified into three positive, negative and neutral classes with a precision level of 0.79 (positive), 0.88 (negative) and 0.77 (neutral) in the logistic regression classifier and 0.92 (positive), 0.87 (negative) and 0.83 (neutral) on the linear regression classifier. Accuracy obtained above 0.8 in both classifiers.
