Abstract

This research presents the development of a web-based e-business application integrated with a data encryption feature using the Data Encryption Standard (DES) algorithm to protect customer privacy. The system is designed for CV Jasa Karya Rizki to manage customer and transaction data securely. DES encryption is implemented manually using PHP without relying on external libraries. The encryption process is applied during data input to ensure that only ciphertext is stored in the database. When data needs to be accessed, decryption is performed on-the-fly, allowing authorized users to view the original information securely. The application consists of core modules for managing customer data, transactions, products, and reports. Encryption and decryption functions are encapsulated within the system's main classes, enhancing maintainability and modularity. Testing results show that the DES implementation functions correctly, providing a secure data management workflow without negatively impacting system performance. This research demonstrates that classic encryption algorithms like DES can still be effectively applied in small-scale business environments to enhance data security and customer trust.

Abstract

This study aims to design and implement an event reservation and payment system to support tourism services at Istana Maimun, Medan. The system was developed to simplify the process of event booking, payment, and management for both users and administrators. The development method adopted was a web-based approach using the Laravel framework and MySQL database. System testing was carried out using the black-box method, focusing on functional requirements such as event creation, reservation processing, and payment confirmation. The testing scenarios included valid and invalid inputs to evaluate the system’s ability to handle different cases. The results showed that all core functionalities performed as expected, with correct status updates and validation messages. The payment module successfully processed transactions and displayed accurate order details, including transaction amounts and unique order IDs. In addition, the system effectively prevented duplicate payments and ensured data consistency between reservations and payment records. Based on these findings, the system is considered functionally ready for production use. It can improve operational efficiency and user experience in managing event reservations at Istana Maimun. Future development may focus on integrating additional features such as online ticket verification and mobile application support.
