New Student Admission Information System (PPDB) at the State Catholic Religious High School of Keerom

Implementation of the New Student Admissions (PPDB) information system at Keerom State Catholic High School using the Waterfall software development method. The development stages include needs analysis, system design, implementation, testing, and maintenance. System testing is carried out using the blackbox method, which is specifically focused on system functionality without looking at the internal code structure. The test results show that all system features, such as online registration, setting periods, and data verification, run well according to needs. The implementation of this PPDB information system has been proven to provide convenience for the committee in managing the admissions process, from registration to selection, and for prospective students in registering boldly. With this system, the PPDB process becomes more efficient, transparent, and well-documented. This success shows that the development and testing approach used is appropriate and effective for the school's needs.
