Aplikasi Inventory dengan Metode FIFO dan LIFO Berbasis Web pada PT. Affas Inti Selaras

Abstract

PT. Affas Inti Selaras faced inefficiencies in managing medical equipment inventory due to reliance on manual bookkeeping and Microsoft Excel. This study developed a web-based application integrating First-In First-Out (FIFO) for perishable items and Last-In First-Out (LIFO) for non-perishable goods. The system was developed using System Development Life Cycle (SDLC) through stages of requirement analysis, UML (Unified Modeling Language) design, PHP-MySQL implementation, and black-box testing with user acceptance trials. Results demonstrated the application successfully: (1) calculated stock accurately using FIFO/LIFO algorithms, (2) generated real-time transaction reports, and (3) reduced recording discrepancies from an initial 22% to below 5% in system trials. Testing with 10 respondents yielded 82% "Good" to "Excellent" ratings, confirming operational readiness for enterprise deployment.
