Limitations of the study: The limitations in this study include several aspects.

Second, data collection that relies on questionnaires and interviews may be influenced by the subjectivity of respondents, so that the results obtained may not reflect the actual conditions. Third, this study only examines member satisfaction from three variables, namely service quality, communication, and trust, without considering other factors such as product innovation, member participation, or cooperative financial stability that can also affect satisfaction. Therefore, further research with a broader scope and a more comprehensive approach is needed to provide a deeper understanding.
