The rapid development of information technology in recent times has had an impact on services in the library. The library is an institution that plays a role in the collection, processing, and distribution of information that prioritizes search engines as a means of information retrieval. The repository is one of the facilities needed by universities to access, store, and publish scientific works of the academic community digitally such as journal articles, e-books, student final project results, and other scientific works. The purpose of this research is to build a repository application to support campus digitization services, especially in the B.J. Habibie library State Polytechnic of Ujung Pandang. The method used to develop this repository application uses the Waterfall method which has a systematic information system development model and consists of stages of needs analysis, software prototype design, implementation, software testing to software maintenance. The software used in developing this repository application uses EPrints. The results of this study are in the form of a library repository application that can be used by all academics, both within the Ujung Pandang State Polytechnic and the wider community. This application is expected to facilitate disseminating the publication of the final project for students of the State Polytechnic of Ujung Pandang and can be accessed widely via the Internet
