Abstract

In the era of digital transformation, cooperatives as people's economic institutions face challenges in managing data and information to support managerial decision-making. Many cooperatives still rely on manual recording systems, resulting in low efficiency, high risk of errors, and limited access to real-time information. This study analyzes the application of computer-based management information systems in the decision-making process at the AMIK Universal Cooperative. The cooperative, which serves students, lecturers, and staff, faces challenges in member data management, savings and loan transactions, and financial reporting that are still done conventionally. This research employs a qualitative case study approach involving in-depth interviews with cooperative managers, system users, and staff. The results show that the application of MIS has improved data management efficiency by 50%, reduced recording errors, and accelerated report preparation by up to 65% compared to manual methods (Khairul et al., 2025). The main success factors include management commitment, user training, and system alignment with business needs. Challenges identified include technological literacy gaps among users and system maintenance costs. This study concludes that computer-based MIS is not just an administrative tool but a strategic instrument for improving the quality and speed of decision-making in cooperatives.
