SISTEM INFORMASI PENGELOLAAN INVENTORY DAN TRANSAKSI BERBASIS WEBSITE PADA NATOPC BATAM

Abstract

NATOPC Batam is a computer retail and PC assembly business that requires integrated inventory and transaction management due to the complexity of product sources, component specifications, pricing, and PC compatibility. The existing operational process still relies on spreadsheets for recording inventory, transactions, payments, and reports. This condition creates difficulties in maintaining stock accuracy, calculating product prices and profit margins, verifying payments, and determining compatibility between PC components. This study aims to design and develop a web-based Inventory and Transaction Management Information System tailored to the operational requirements of NATOPC Batam. The system was developed using the Waterfall method, consisting of analysis, system design, implementation, testing, deployment, and maintenance stages. Requirements were collected through interviews with NATOPC representatives. The application was implemented using the Laravel framework and MySQL database and integrates the Midtrans payment gateway in a sandbox environment. The main features include multi-supplier inventory management, product specification management, customer and supplier management, digital transactions, automatic stock updates, transaction and stock reports, dynamic price and profit margin calculations, and a PC assembly simulation based on component compatibility. System evaluation was performed using Black Box Testing and User Acceptance Testing (UAT). The functional testing showed that the tested features operated according to the defined requirements, while the UAT obtained an average score of 91%, categorized as Highly Feasible. These results indicate that the developed system is feasible to support the operational management of NATOPC Batam.
