Abstract

Micro and Small Enterprises (MSEs) often struggle with warehouse and inventory management due to manual recording processes, limited system integration, and the absence of real-time stock visibility. These challenges contribute to stock inaccuracies, delayed restocking decisions, and operational inefficiencies. This study develops a real-time Warehouse Management System (WMS) using the Laravel framework to support the operational activities of Toko Karomah, a small retail business in East Java, Indonesia. The system integrates core features such as item master data, stock-in and stock-out modules, user role management, and real-time stock updates supported by reorder point thresholds. The development process follows the Waterfall methodology, covering requirements analysis, system design, implementation, testing, and deployment. The results show that the system effectively improves stock accuracy, reduces the risk of stock-outs, and enhances workflow efficiency. User Acceptance Testing (UAT) confirms that the system meets functional and usability requirements. This research demonstrates that a Laravel-based real-time WMS can significantly support digital transformation for MSEs, especially in inventory-critical operations.

Abstract

The manual grading of tobacco, a critical process determining its market value, is inherently subjective, labor-intensive, and prone to inconsistency. This study investigates the application of deep learning to automate the quality classification of Madura sliced tobacco, a high-value agricultural commodity. A novel, high-fidelity dataset was created, comprising 1,065 high-resolution images captured under standardized lighting and environmental conditions. An expert tobacco sorter with over five years of professional experience meticulously labeled these images into four distinct quality grades: Grade A (premium), Grade B (medium), Grade C (lower), and Grade X (waste). This research presents a rigorous comparative analysis of four pre-trained deep learning architectures MobileNetV3-Small, ResNet18, MobileViTV2, and EfficientNet-B0 fine-tuned for this specific classification task. Employing a 5-fold cross-validation methodology, the models were evaluated on their ability to accurately classify the tobacco grades. The experimental results reveal that the lightweight MobileNetV3-Small architecture achieved the highest mean test accuracy of 56.87%±2.71%. A detailed error analysis indicated that all models performed well on the majority classes but struggled significantly with the underrepresented minority classes, a challenge attributed to the dataset's severe class imbalance. This study validates the potential of lightweight deep learning models for automating tobacco classification, offering a promising pathway toward enhanced objectivity and efficiency in the agricultural industry. Furthermore, it establishes a crucial benchmark and identifies class imbalance as the primary obstacle to be addressed in future research for developing a field-deployable system.

Abstract

Public street lighting (LPJU) are vital facilities that assist and support community activities, especially at night. However, various problems with LPJU are still frequently encountered. Some common problems include lights going out at night, lights that are on during the day, or a specific component of the light broken. These problems are often not immediately recognized by authorities due to the lack of a fast and structured reporting system, resulting in the repair process often being delayed and having a negative impact on road users. The LPJU fault reporting system in various regions is also still manual. The purpose of this research is to design and develop an Android-based public street lighting damage reporting application to make it easier for the public to submit LPJU damage reports digitally by attaching descriptions, photos, and the location of the incident in real time. This application was developed using one of the approaches, the waterfall method. The research results show that this application can assist and facilitate the public in digitally reporting LPJU damage. Implementation of this system is expected to improve reporting efficiency, expedite follow-up on LPJU damage, and serve as a model for technology-based public service within local governments.
