Pengembangan Sistem Penilaian Kinerja Karyawan Berbasis HRIS Menggunakan Metode Simple Additive Weighting (Studi Kasus: PT Cozi Mitra Mandiri)

The employee performance assessment at PT Cozi Mitra Mandiri was previously manual, making data processing and ranking less efficient and prone to subjectivity. This study develops a web-based employee performance assessment system integrated into a Human Resources Information System (HRIS) using the Simple Additive Weighting (SAW) method, in which eleven assessment criteria and their weights were determined by the company's HR division based on company policy. The system was developed using the SDLC framework with the Kanban method (PHP, MySQL). Its novelty lies not in applying SAW alone, but in integrating attendance data, assessment, automated SAW computation, and ranking within a single HRIS workflow that uses the company's operational data. Testing used Black Box Testing and the System Usability Scale (SUS). All eight functional scenarios passed (100%), the preference values ranged from 1.0000 to 0.4165, and SUS with 10 respondents obtained an average of 68.75, which falls in the marginally acceptable range (grade C, adjective rating near OK/Good). The system makes the assessment process more structured, integrated, and automated. This study is limited to a single company and ten usability respondents, so broader validation is left for future work.
