<![CDATA[The development of information technology has significantly contributed to improving administrative performance, including in village government institutions. The implementation of web-based information systems enables data processing, storage, and retrieval to be carried out more quickly, accurately, and systematically. In the village government environment, the management of incoming and outgoing mail archives is an essential component in supporting administrative activities and public services. Mail archives serve as official documents and administrative evidence that hold important value in decision-making processes. However, at the Nanganesa Village Office, the archiving process is still conducted manually using agenda books and physical document storage, leading to several challenges such as slow document retrieval, difficulty in tracking archives, and the risk of data loss or damage.Based on these problems, this study aims to design and develop a web-based mail archiving information system by implementing the Sequential Search algorithm. This algorithm is applied to assist in searching archive data sequentially, making it easier for users to find the required documents. The system development method used is the waterfall model, which includes the stages of requirement, design, implementation, verification, and maintenance. Data collection was carried out through observation, interviews, and literature study. The analysis technique used is the Sequential Search algorithm, which is a search method that works by comparing data sequentially from the first index until the searched data is found or all data has been examined, with a complexity of O(n) — Linear. The results show that the web-based mail archiving information system was successfully built and is capable of searching mail archive data based on keywords such as letter number, origin, subject, and letter nature. The system also provides features for managing incoming mail, outgoing mail, archives, reports, and trash, which can be accessed by the Admin and Village Head according to their respective access rights. With this system, the management and retrieval of mail archives at the Nanganesa Village Office can be carried out more effectively, efficiently, and systematically.]]>
