Balai Pengkajian dan Pengembangan Komunikasi dan Informatika (BPPKI) Surabaya has personnel data that needs to be stored and processed in order to facilitate computerized storage and reporting. The implementation of a web service information system is a collection of functions or methods contained on a server that can be called by clients remotely. Clients can be users who use the desktop application implemented in this study, or the web as a mobile communication device. The implementation of the Three Tier application model architecture is in terms of infrastructure and documents used as data exchange formats. The Human Resources Management Information System application was developed using the Three-Tier desktop-based method with the prototype method. The Human Resources Management Information System application consists of four key components: the transaction process information system for periodic salary increases, salary, rank promotions, and leave requests; simplifying report generation; and minimizing data input errors. The implementation and results of black box testing show that all form features tested on the human resources management system functioned successfully and as expected, making this application suitable for implementation to assist human resources management at Balai Pengkajian dan Pengembangan Komunikasi dan Informatika (BPPKI) Surabaya.
