Abstract

This research aims to design and develop a web-based Notary Management Information System (MIS) incorporating the AES 256 encryption algorithm to enhance data management and security in notary offices. Utilizing the Rapid Application Development (RAD) methodology, the system was developed through iterative collaboration between developers and users to meet both functional and non-functional requirements. Key features of the system include the management of order data, client records, notarial protocols, and user activity logs. The innovative application of the AES 256 algorithm ensures high-level data security, with validation tests confirming its effectiveness in protecting sensitive information. Performance testing demonstrated significant improvements, including a 40% reduction in data retrieval time and seamless encryption processes, compared to previous manual methods. The system also enhances accessibility and work efficiency through its web-based architecture. This research not only provides a practical solution for notary offices but also serves as a scalable model for secure MIS development in other industries.

Abstract

Retail businesses, particularly hardware stores, often encounter challenges in order management such as delayed deliveries, inaccurate stock tracking, and limited information transparency factors that hinder operational efficiency and customer satisfaction. This study proposes a web-based order management system utilizing Progressive Web Apps (PWA) technology, developed with the Next.js framework. The Periodic Review System (PRS) method is implemented to calculate reorder points based on actual demand and safety stock levels. System development follows the Waterfall model, with data collected through observation, semi-structured interviews, and literature review. Testing confirms that the application enhances stock accuracy, minimizes delivery delays, supports offline access, and meets SEO performance standards. The implementation significantly improves operational efficiency and holds promise for boosting customer loyalty. The study concludes that PWA-based digital systems are practical, scalable solutions for the MSME sector, with future potential for integration of AI, CRM, and real-time analytics.
