The Department of Agriculture, Food, Marine Affairs, and Fisheries (DPPKP) of Central Papua Province faces significant challenges in document archive management that is still performed manually. This research aims to develop a web-based document archive application to improve archiving efficiency and support digital transformation in the government sector. The research methodology uses a software engineering approach with the Waterfall method covering five stages: requirements analysis, system design, implementation, testing, and maintenance. The application was developed using PHP, MySQL, and Bootstrap with main features including document upload/download, category and keyword-based search, and authentication system for data security. Black-box testing results show all system functions operate according to user requirements with 100% success rate. System implementation successfully reduced document search time from an average of 10 minutes to less than 2 minutes, increasing employee work efficiency by 75%. Performance evaluation shows an average response time of 1.2 seconds with 99.7% system availability. This research contributes to government information system development literature and provides practical solutions for archive digitalization in regional government agencies.

Manual handling of incoming letters in government institutions often results in inefficiencies in recording, tracking, and disposition delivery. This study aims to develop a Java-based application for managing incoming letter dispositions to enhance administrative efficiency at the Office of Population Control and Family Planning (DPPKB) of Nabire Regency. The system was developed using the waterfall method, which includes the stages of analysis, design, implementation, testing, and maintenance. The results show a 30% increase in disposition speed and a 50% decrease in recording errors. Furthermore, the application supports real-time letter tracking and role-based user access. The findings indicate that digitizing the letter disposition system can significantly accelerate administrative processes and reinforce the principles of good governance.

The involvement of the community in the development of a web-based photo ordering application using the waterfall method aims to improve customer service during the online photo ordering process. The background of this community service is based on the difficulties faced by the public in practically ordering photos. The main goal of this community service is to develop an application that simplifies the ordering process. The development method used is the waterfall method, which includes analysis, system design, implementation, testing, and maintenance. The results of this application development include the results of each development stage with the waterfall method, implementation results, and the main conclusion of this community service.
