The Printed Circuit Board (PCB) industry increasingly relies on automation and digitalization to improve efficiency and accuracy in production and distribution processes. One common practice is the use of labels containing product information in the form of barcodes or QR codes, which allow automatic data input and reduce the risk of human error compared to manual writing. However, in current practices, these labels are only attached to PCBs after they have been placed inside casings. This creates a significant limitation, as access to the label information requires disassembling the casing whenever product verification, tracking, or troubleshooting is needed. Such a process not only consumes additional time and resources but also increases the risk of damaging the product. To overcome this challenge, this study proposes the development of a traceability system designed to accurately monitor the location, identity, and status of PCBs throughout the distribution process. The system was implemented as a web-based application capable of generating and printing product information labels in the form of barcodes and QR codes. Each label functions as a unique identifier, ensuring that every PCB can be distinctly tracked from production to final product assembly. All data associated with the labels is automatically stored in a centralized database, providing real-time accessibility, simplifying information management, and enabling faster decision-making in the event of quality control issues. System evaluation was carried out through rigorous testing, which showed a 100% success rate in generating, storing, and retrieving product information without errors. The findings indicate that the proposed traceability system is both effective and efficient, and it offers a practical solution for industries seeking to enhance supply chain visibility, improve product accountability, and reduce operational inefficiencies in PCB distribution and lifecycle management.

We designed and implemented a web-based inventory system to address challenges in managing inventory and financial data at Toko bangunan Mutiara. With high daily transaction volumes and a wide variety of products, manual recording often leads to errors, inaccuracies in inventory data, and difficulties in monitoring cash flow. To address this, we developed the system using the Agile/Scrum development model, which allows for flexibility and adaptation to user needs through the stages of Requirements, Design, Development, Testing, Deployment, and Review. The system was developed using web technology, including PHP and JavaScript for the backend, HTML and CSS for the frontend, and MySQL as the database system. The main features we implemented include two integration options: barcodes and unique product codes to simplify recording, automatic notifications when stock reaches the minimum level set by the system, and the ability to generate accurate reports. It is hoped that this research, which was designed to enhance operational efficiency in recording incoming and outgoing goods, provide flexible and accurate access to inventory data, and minimize errors in recording and inaccurate data, will be successful.

Personal data dissemination is a new type of crime that has emerged in the digital world. The rapid development of technology has led to various innovations in data storage, one of which is through barcode technology. Although it provides convenience, this technology also opens up new gaps in cybercrime, especially the misuse and dissemination of personal data stored in barcodes. The impacts of the spread of personal data include damage to personal reputation due to the widespread dissemination of personal data on the internet, the emergence of cyber bullying and sexual harassment, personal data that has the potential to be sold, and the distress and psychological trauma experienced by victims of personal data dissemination. The purpose of this study is to analyze how law enforcement against perpetrators of abuse of the spread of personal data stored in barcodes is reviewed from the ITE Law and the PDP Law, and identify preventive efforts that can be made to prevent these crimes. This research uses a normative juridical approach method used to examine applicable legal norms related to personal data protection. With a statute approach, books, scientific journals, and the internet. The results showed that, although the ITE Law does not specifically regulate barcode technology, the protection of personal data stored in barcodes is still subject to the provisions of the ITE Law and Law Number 27 of 2022 concerning Personal Data Protection.

With 65 million entities, micro, small, and medium enterprises (MSMEs) form the backbone of the Indonesian economy, contributing around 61% of the country's gross domestic product (GDP) and employing 97% of the working population. Despite their strategic role, most MSMEs still face various challenges, such as low adaptability to changes in the business environment, lack of planning strategies, minimal innovation, and limitations in utilizing technology. On the other hand, current consumer behavior increasingly demands quality products and practical services, including in terms of payment systems. Along with the development of the digital era, non-cash payment systems, such as e-money and QR codes, have experienced rapid growth and become important elements in encouraging financial inclusion and transaction efficiency. QRIS (Quick Response Code Indonesian Standard) is present as an innovative solution that allows MSMEs to make transactions quickly, safely, and easily by simply scanning a QR code. Realizing the importance of utilizing this technology, the community service (PkM) team conducted training activities on the creation and use of QRIS for the "Zea Ice" Orange Juice micro business actor in Deltasari Indah, Sidoarjo, East Java. This activity includes QR code creation, printing, and attaching barcodes to kiosks, as well as technical education related to their use. This initiative is expected to increase transaction efficiency, encourage the implementation of digitalization, and increase the competitiveness of MSMEs in an increasingly competitive market.
