Abstract

The process of new student admission involves the collection and management of sensitive personal data, which requires strong data security to prevent misuse and unauthorized access. SMP Swasta Pencawan Medan faces challenges in ensuring the confidentiality and integrity of prospective student data in its web-based admission system. This study aims to develop a secure web-based new student admission system by implementing data security mechanisms to protect against common web attacks such as SQL Injection, Cross-Site Scripting (XSS), and Cross-Site Request Forgery (CSRF). The research method used is system development, which includes system analysis, design, implementation, and testing. The system is developed using PHP as the programming language and MySQL as the database, with the application of the SHA-1 algorithm to secure sensitive data such as passwords. The results show that the developed system is capable of improving data security, maintaining data integrity, and preventing unauthorized access. The implementation of security mechanisms in the system contributes to a safer and more reliable new student admission process, thereby increasing trust from parents and the community.

Abstract

Efficient use of electrical energy is a crucial aspect in the management of public facilities, including houses of worship. In church parking areas, manual lighting systems often lead to electricity waste. This research aims to implement lighting automation technology by utilizing an Arduino Uno microcontroller and a Light Dependent Resistor (LDR) sensor. Through a prototype design approach, this system was developed to detect the level of light intensity in the surrounding environment in real-time. Test results show the effectiveness of the system in controlling the lights: the device will activate the lights when the light intensity is above 850 lux (dim/dark conditions) and deactivate them when below 849 lux (bright conditions). The implementation of this innovation is expected to reduce electricity operational costs while increasing safety factors in the church environment.

Abstract

Beauty salons are service businesses that require precise management of service schedules and product stocks to maintain service quality and customer satisfaction. Manual reservation and stock management has the potential to cause recording errors, schedule conflicts, and product inventory discrepancies. Therefore, this study aims to design and implement a web-based Harni Salon Reservation and Stock Information System. The research methods used include system requirements analysis, system design using modeling diagrams, PHP and MySQL-based system implementation, and functional testing using the black box testing method. The results of the study indicate that the system is able to manage customer data, services, reservations, and product stocks in an integrated manner and displays reservation and inventory report information well. This system also allows customers to make service reservations independently based on available schedules, while the admin can confirm reservations and monitor product stocks in real-time. The conclusion of this study is that the implementation of a web-based information system can improve operational efficiency and service quality at Harni Salon. The benefits of this study are expected to be a reservation and stock management solution for salon businesses and become a reference for the development of similar systems in the future.
