Abstract

In general, COBIT 5 is a framework that helps to focus on Governance and management which includes 2 main areas, namely Governance and Management. So that this study applies the COBIT 5 framework to a library institution at Sari Mulia University. In this study, we used COBIT 5 domains, namely EDM04 (Ensure Resource Optimization) and DSS02 (Manage Service Requests and Incidents), both of which focused on optimizing resources (IT) as well as managing service requests and incidents. This study uses methods that include qualitative and quantitative approaches by collecting data through interviews and surveys. The results show that the implementation of COBIT 5 can improve the efficiency of IT resource use as well as improve the response to IT service incidents. The average level of IT maturity is at level 3 (Established), although there are some gaps that need to be addressed to reach the optimal level. This research provides important insights for libraries in optimizing IT governance to support better services.

Abstract

The advancement of information technology in higher education requires a reliable network infrastructure to support academic, research, and administrative activities. This study aims to design a computer network infrastructure for Building E at Sari Mulia University using the Waterfall model. The research includes needs analysis, system design, simulation-based implementation with Cisco Packet Tracer, and performance evaluation. The needs analysis identifies user requirements, devices, and applications to ensure the network supports high-speed internet, central server connectivity, and e-learning systems. The proposed design uses a hierarchical topology with core, distribution, and access layers, along with VLANs to optimize data traffic and reduce congestion. The simulation results showed that the network design performed as expected, with a success rate of 90-95%. However, improvements are needed, particularly in the wireless network (WLAN), where coverage was insufficient in certain areas due to limited access points and physical barriers. In conclusion, the network design effectively supports the university's academic and administrative needs, with room for growth and future technology integration.
