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. The implementation of this system contributes to more accurate inventory management and supports better financial decision-making for Toko bangunan Mutiara.

Image denoising is a fundamental challenge in image processing, where the objective is to remove noise while preserving critical image features. Traditional denoising methods, such as Wavelet, Total Variation (TV) minimization, and Non-Local Means (NLM), often struggle to maintain the topological integrity of image features, leading to the loss of essential structures. This study proposes a Cubical Persistent Homology-Based Technique (CPHBT) that leverages persistence barcodes to identify significant topological features and reduce noise. The method selects filtration levels that preserve important features like loops and connected components. Applied to digit images, our method demonstrates superior performance, achieving a Peak Signal-to-Noise Ratio (PSNR) of 46.88 and a Structural Similarity Index Measure (SSIM) of 0.99, outperforming TV (PSNR: 21.52, SSIM: 0.9812) and NLM (PSNR: 22.09, SSIM: 0.9822). These results confirm that cubical persistent homology offers an effective solution for image denoising by balancing noise reduction and preserving critical topological features, thus enhancing overall image quality.

Permen ATR/BPN 9/2019 is a provision regarding the implementation of roya electronically so that registration and deletion of roya can be reached easily, quickly, simply and at low cost. Roya which is done manually is different from electronic. The difference is that the file from the applicant is scanned and registered through the website and is directly corrected by the roya executor, not through the land counter. So that the Notary/PPAT does not have to come to the Land Office. After obtaining the certificate of land rights then it is given back to the certificate holder in this case is the creditor. If the deletion and registration of roya electronically has not been carried out even though the debt has been paid off, the land title certificate still contains a barcode record of encumbrance of Mortgage Rights. Based on the above, how is the implementation of the elimination of Roya Mortgage Electronically at the Land Office of Batang Regency? And what are the Inhibiting and Supporting Factors in the Implementation of Electronic Mortgage Elimination at the Land Office of Batang Regency?. The research method that will be used in this paper is a sociological juridical research method. The approach that the author uses in this study is a sociological juridical approach. The sociological juridical approach emphasizes research that aims to obtain legal knowledge empirically by going directly to the object. The implementation of the abolition of roya with the HT-el System at the Land Office of Batang City has not all been carried out in accordance with the procedures stated in the Technical Guidelines for HT-el. Application files that do not comply with procedures are known from the results of the inspection of the Land Office, if not checked, the HT-el certificate will be issued automatically on the seventh day. Issuance without any inspection from the Land Office if there is a procedural error, it is feared that it will become a problem in the future. Obstacles in HT registration with the HT-el System occur in PPAT, Banks as creditors and the Land Office. This obstacle arises during the HT registration process, both technically and non-technically. The electronic roya removal is carried out by the applicant, namely the debtor, proxy or representative by filling out an electronic application. If seen in practice, the Elimination of Roya electronically electronically or online is carried out through PPAT intermediaries at the PPAT office because PPAT who has a user name and password when accessing the registration system for the Elimination of Roya electronically in order to serve the needs of the community for the Elimination of Roya electronically through the online system still has both external and internal constraints.   Keywords: Deletion, Roya, Online
