Abstract

Manual inventory management often leads to various issues such as inaccurate recordkeeping, delays in procurement processes, and difficulties in monitoring stock levels in real time [9]. This study aims to develop a web- and mobile-based inventory management information system using the Waterfall method. The web system was developed using PHP and MySQL, while the mobile application was built using Flutter to provide flexible access for users. The main features of the system include recording incoming and outgoing goods, real-time stock monitoring, and automatic notifications when stock reaches a minimum threshold. The test results indicate significant performance improvements compared to the previous manual process. Based on quantitative evaluation, the accuracy of stock recording increased from 82% to 98% after implementing the system, while the time required to complete stock recap activities was reduced from an average of 45 minutes to 12 minutes per session. In addition, the automatic notification feature accelerated the procurement process—from an average of 6 hours after stock depletion to only 1–2 hours for follow-up actions. Blackbox testing also confirmed that all system functions operated correctly under both normal and error scenarios. With this system, inventory management becomes more structured, accurate, and efficient, supporting faster and data-driven decision-making.

Abstract

Subnetting is a fundamental concept in computer networking that is often considered difficult due to its complex calculation process and the limited availability of interactive learning media. This study developed SubnetLab, a web-based learning application that provides user authentication features, an automatic subnetting calculator, binary representation, and a reset function to support independent exploration of the concept. The study used a Research and Development (R&D) method through the stages of needs analysis, design, implementation, and functional testing. The application was built using HTML, CSS, and JavaScript with account storage on localStorage. The results showed that SubnetLab was able to perform subnetting calculations accurately and display results in decimal and binary formats. All main features functioned well and supported usability aspects in the basic usage scheme. However, this study did not evaluate the effectiveness of learning or increase user understanding, so further studies are needed to assess the pedagogical impact of the application more comprehensively. Based on these findings, SubnetLab has the potential to be further developed as an independent learning medium or as a companion for computer networking practicums.
