| The traditional orientation, focusing on the collection, is no longer appropriate for satisfying users in the present era. Thus, identifying a new model to measure library service quality and designing a systemic method to enhance quality are necessary for academic libraries. To improve the quality of service, customer satisfaction measurements on the quality of service are provided using Importance Performance Analysis (IPA) and Decision Making Trial and Evaluate Laboratory (DEMATEL) methods. The IPA method can be classified for the required attributes and the DEMATEL method can provide relationships between attributes that can be used to improve library user satisfaction. The subject of the research is the end of the day that comes at least once a week. The sample used in this study amounted to 176 respondents with sampling technique purposive sampling. There are 22 attribute statements that are in IPA divided into four quadrants and obtained from IPA there are 6 attributes not according to user request and need immediate repair. The first quadrant is there are 6 attribute attributes for improvement, the second quadrant exists. The results obtained from the measurement on the IPA method obtained 6 attributes not in accordance with user demand and repair needs, the second quadrant there are 4 attributes required. , and the last quadrant there are 6 excess attributes. Attributes that need improvement are in the first quadrant attribute (top priority). The sequence of attribute improvements on the main foundations is based on the DEMATEL method: libraries can assist in tackling unions experienced by library visitors; the existence of information sources of information in the form of books, journals, and literature; library staff have the knowledge to answer visitor questions about libraries; libraries providing journals / electronic literature accessible from home or elsewhere outside the library; there are facilities for study / conducting research in groups; library staff helps library users with smiles. |
