The importance of developing an interactive digital ledger of the history of North Sumatra which is open access for students of history majors/study programs as a learning resource is the main background for the implementation of this research. In addition, to respond to government programs, especially in the world of education with the implementation of the Merdeka Learning Campus Independent curriculum, and to answer the challenges of education in the Industrial Revolution Era 4.0. Lecturers and students in their learning, especially the History of North Sumatra course, tend to use printed books whose content is less relevant to Graduate Learning Outcomes and Learning Outcomes Department of History Education Faculty of Social Sciences UNIMED. This condition is due to the existence of printed books that currently contain limited material about the geographical, economic, and socio-cultural conditions of several regions of North Sumatra with a time limit of only the 20th century. Studies on the existence of figures and the development of art by artists, especially composers, especially musicians and composers, such as Liberty Manik with the national anthem Satu Nusa Satu Bangsa, for example, are almost untouched. Therefore, the use of the interactive digital-based History of North Sumatra ledger will greatly facilitate students in exploring learning resources in the form of digital, multimedia such as audio, video, animation, photos, graphics, and so on, especially in the current era of the covid-19 pandemic. In addition, the digital application will give students access to other sources such as historical archives from sites such as the National Library, KITLV, and the Indonesian National Archives, to the acquisition of the latest scientific articles through national and international links available on digital applications. Therefore, research on the development of an interactive digital ledger of the History of North Sumatra is very important to do.
