Sistem Pengelolaan Inventori Real-Time untuk UMKM Berbasis Flutter dan QR Code Menggunakan Metode R&D

Introduction

Sistem pengelolaan inventori real-time untuk umkm berbasis flutter dan qr code menggunakan metode r&d. Tingkatkan efisiensi UMKM dengan sistem inventori real-time berbasis Flutter & QR Code. Akurasi data 95%, waktu transaksi berkurang 70%. Solusi digitalisasi pengelolaan stok.

Abstract

The efficiency and accuracy of stock recording in MSMEs are enhanced through the development of a mobile-based inventory management application, addressing the challenges of manual systems, which are prone to human error and data delays. This study implements a real-time system by integrating three key technologies: Flutter as a cross-platform framework for efficient development, QR Codes for rapid item identification, and Firebase as a database for instant data synchronization. By applying the R&D method through the Waterfall model, the application was developed and tested in a case study at Warung Laras. The application is equipped with essential features for daily operations, including security verification using OTP via WhatsApp, unique QR code generation for each item, and the ability to automatically generate inventory reports in PDF format. The results from Black Box testing and user trials show a significant quantitative impact: data recording accuracy increased to 95%, while the average time per transaction was drastically reduced by 70%, from approximately 30 seconds to just 9 seconds. This finding proves that the technological integration has successfully created a reliable and effective solution to drive digital transformation in MSME-scale stock management

Review

This paper presents a highly relevant and practical approach to addressing the persistent challenges of inventory management within Micro, Small, and Medium Enterprises (MSMEs). By developing a real-time, mobile-based application, the authors directly tackle the inefficiencies, human errors, and data delays commonly associated with traditional manual systems. The proposed solution leverages a well-chosen technological stack—Flutter for cross-platform development, QR codes for streamlined item identification, and Firebase for robust real-time data synchronization—demonstrating a considered design aimed at enhancing operational accuracy and speed for this critical economic sector. The core strength of this work lies in its integrated technological application and the compelling quantitative results it presents. The abstract highlights essential features such as OTP-based security, automated unique QR code generation, and the invaluable capability to generate inventory reports in PDF format, all of which directly cater to MSME operational needs. The empirical data derived from Black Box testing and user trials at Warung Laras is particularly impressive, showcasing a substantial increase in data recording accuracy to 95% and a drastic 70% reduction in average transaction time, from 30 seconds down to a mere 9 seconds. These significant improvements strongly validate the application's effectiveness and its potential to foster digital transformation in MSME-scale stock management. While the abstract provides a strong overview of the solution's development and positive impact, a more detailed exploration in the full paper could further enrich its contribution. A discussion on the generalizability of results beyond a single case study, Warung Laras, or an analysis of the long-term user adoption rates and potential scalability challenges for MSMEs with more complex operational structures would be beneficial. Nonetheless, this study clearly demonstrates the successful creation of a reliable and effective technological solution for a crucial problem, offering a promising blueprint for enhancing efficiency and driving digitalization within the MSME sector.
