Pengembangan Sistem Monitoring Persediaan Barang Berbasis Web Menggunakan Metode Reorder Point (ROP) Pada PT BXX

Abstract

Inventory management at PT BXX still involves manual or semi-computerized stock recording, which may result in discrepancies between recorded and actual stock information and delays in stock updates. Although previous studies have developed web-based inventory systems and implemented Reorder Point (ROP) methods, their applications differ in organizational context, inventory requirements, and evaluation design. This study aims to develop a web-based inventory monitoring system that applies the ROP method to support inventory monitoring and reorder identification at PT BXX. The study employed the Research and Development (R&D) method with the Waterfall development model. The system was implemented using the Laravel framework and MySQL database and provides inventory management, incoming and outgoing transaction recording, stock monitoring, ROP calculation, minimum-stock notification, and reporting features. Functional evaluation was conducted using Black Box Testing, while perceived usability was evaluated using the System Usability Scale (SUS). Black Box Testing showed that the tested functions conformed to the specified requirements. The SUS evaluation involving 14 respondents produced an average score of 82.14, indicating an Acceptable level of perceived usability. These results indicate that the developed system provides the tested inventory monitoring and ROP functions and was perceived as usable by the evaluated respondents.
