The design of the library information system utilizes literature study analysis methods, observations, interviews and RCA (Root Cause Analysis) directly to students and librarians. RCA is also used as an analytical approach to a system design to understand an event in detail. This information system design documentation employs Unified Modeling Language (UML) modeling, namely use case diagrams, class diagrams, activity diagrams and sequence diagrams, it is hoped that the results of analysis and design can facilitate library services and increase the effectiveness of the lending process and book data collection.
