Universitas Muhammadiyah Yogyakarta (UMY) is one of the largest university in Yogyakarta which was established in 1981. UMY has eight faculties and seven master programs. No wonder if the research generated by UMY every year is growing. Scientific and research article are stored in digital repository that are currently managed by UMY Library. Digital Repository should be able to make the university become more popular by its indexed repository site in search engine. However, UMY Repository currently has low index and is not listed in the world rangking such us webometrics or 4ICU. With the building of the new Repository UMY using Dspace application which has tools for indexing website, UMY Repository should be more easily indexed by search engine. So, website UMY Repository can be listed on search engine, Webometrics, and 4ICU. Website UMY Repository built with waterfall method: Analysis, Design, Implementation, and Testing. Thus, building of the system will be more focused despite taking quite a long time. With building of new website UMY Repository, UMY Repository and Muhammadiyah University of Yogyakarta will be more known by the world with the benefits of research that can be usefull for people in need.
