Abstract

This research aims to analyze the influence of transformational leadership, work environment, internal communication, and organizational commitment on the quality of internal services at the Class III Airport Operating Unit of South Papua Province. The research method used is quantitative with a survey approach, where data is collected through questionnaires from airport employees which are then analyzed using regression analysis. The research results show that these four variables have a positive and significant influence on internal service quality. Effective transformational leadership, a conducive work environment, good internal communication and strong organizational commitment contribute significantly to improving the quality of internal services at the airport. These findings provide practical implications for airport management to focus on improving these factors to improve the quality of services provided.

Abstract

This study aims to explore the implementation of Classroom Action Research (CAR) as a professional development strategy for teachers across various areas of educational services at SMP Negeri 21 Kota Bekasi. Using a descriptive qualitative approach with a case study design, the research involved teachers as the primary subjects, with school principals and students as supporting data sources. Data were collected through observation, interviews, questionnaires, and documentation, and analyzed using the Miles & Huberman model. The findings indicate that CAR enhances teachers' pedagogical, professional, social, and personal competencies. Furthermore, it strengthens educational services such as academic instruction, counseling, and classroom management. The study also reveals several structural and cultural challenges, which can be addressed through school management support and a collaborative culture. CAR is proven to be an effective reflective strategy for improving the quality of learning while empowering teachers as facilitators of change in the classroom.

Abstract

The futsal pitch rental process at Golden Goal is still done manually through direct communication or text messages, which often results in various problems such as unstructured booking queues, schedule conflicts due to the lack of a clear queuing system, and late payments. These problems result in low operational efficiency and an increased potential for scheduling errors. This research aims to develop a mobile-based futsal pitch rental application equipped with the implementation of the First Come First Serve (FCFS) algorithm to ensure the booking process is carried out based on the user's arrival time in a fair and orderly manner. The system development method used is the Waterfall model, which includes requirements analysis, design, implementation, testing, and maintenance. The application was developed using the Flutter framework because it has the ability to produce Android and iOS applications with only a single codebase, faster development time, and stable and responsive interface performance. These advantages make Flutter suitable for building a real-time booking system that requires fast interaction and a consistent user experience. Furthermore, the application is integrated with Midtrans services as a payment gateway to facilitate automatic digital payment transactions. Testing results using the black-box method indicate that all key features, including schedule selection, FCFS-based queuing mechanism, payment processing, and rental data management, have run well as needed. The implementation of this system has proven to be able to reduce schedule conflicts, improve the accuracy of the booking process, and increase the efficiency of rental management at Golden Goal. Thus, this application can be an effective and modern solution to address the problem of futsal field rentals that have been handled manually.
