Abstract: The implementation of green computing-based information systems in the school environment is still low. This is marked by the use of paper that is still liked by the school. For this reason, it is necessary to design information systems based on green computing to archive letters that have been created or received by schools. The letter that has been archived will make it easier for schools to search, avoid losing files when moving from one person to another. Those who have authority in archiving will certainly be easy to monitor.
