This study aims to analyze the use of the Electronic Official Manuscript (NADINE) application in managing archive documents at LEMIGAS as part of the implementation of digital transformation in government agencies. NADINE is an electronic correspondence system that includes the process of inputting, verifying, disposing, and storing documents in PDF format. This study uses a descriptive qualitative approach with a case study method, through interview techniques, observation, documentation, and literature studies. Informants consisted of one key informant (Head of the Archives Building) and three active NADINE users. The results of the study show that the implementation of NADINE makes a significant contribution to increasing the efficiency and effectiveness of archive management. This application facilitates online document access, supports work flexibility, and speeds up the search process through features based on letter numbers or sender names. However, there are still technical obstacles such as dependence on internet connections, suboptimal features, and the lack of integration of static archives and archive destruction systems. From a non-technical perspective, challenges include limited training and readiness of human resources in adopting digital technology. This study is expected to be a recommendation for the development of the NADINE system for other agencies in implementing electronic archive management effectively and sustainably.
