Abstract

Manual booking and scheduling processes at the Arton Futsal court frequently result in double-booking issues, inaccurate schedules, and inefficiencies for customers who must check availability directly on-site. This study aims to design and implement a web-based reservation and scheduling information system for Arton Futsal to streamline business operations and improve customer convenience. The research utilizes a Project-Based Research (PBR) approach with mixed methods, applying the Waterfall development model using PHP and MySQL. The authentication and authorization flow of the system defines two distinct user levels with specific login access: Admin (manager) and Member (customer). System evaluation was conducted through Black Box Testing, and user friendliness was measured using the System Usability Scale (SUS) questionnaire. The results indicate that the developed system successfully automates court scheduling, minimizes data duplication or overlaps, and provides real-time information on field availability, thereby enhancing administrative efficiency and user satisfaction.

Abstract

The magnetic field is a fundamental concept in physics with significant roles in various natural phenomena and technological applications. This study aims to analyze the basic theory of magnetic fields, their applications in technology, and their impact on natural phenomena. Based on a literature review, it was found that the magnetic field is closely related to electromagnetic laws such as Ampère's and Faraday's laws, leading to practical applications such as electric motors, generators, and medical technologies like MRI. Additionally, Earth's magnetic field protects life from cosmic radiation and influences natural phenomena like the aurora. This study also highlights the role of magnetic fields in modern physics, particularly in particle physics experiments and quantum field theory. The findings emphasize the importance of understanding magnetic fields for technological development and scientific research in the future.
