Abstract

This study examines the influence of motivation, job training, and work discipline on employee performance at the Airport Authority Office, Region II, Deli Serdang, North Sumatra. In air transportation organizations, the quality of human resources plays a crucial role in ensuring smooth operations, flight safety, and improving the quality of public services to service users. This is the core of the success and sustainability of operations in the aviation industry. This study used a descriptive quantitative approach. The research sample consisted of 107 respondents, determined using the Slovin formula from a total population of 146 people. Data collection techniques included questionnaires, structured interviews, and direct observation of the research subjects. This method aimed to obtain accurate and relevant primary data. The collected data were then analyzed using multiple linear regression with the aid of statistical software. This analysis aimed to determine the simultaneous and partial influence of each variable on overall employee performance. The results showed that motivation, job training, and work discipline had a positive and significant influence on employee performance. Both partially and simultaneously, these three independent variables contributed to improved performance. This proves that effective and targeted human resource management can create a more productive, professional, and efficient work environment. This research provides a practical contribution to formulating more optimal human resource management policies, particularly in the air transportation services sector. The goal is to enable organizations to continue to grow, improve operational efficiency, and maintain sustainable competitiveness in facing future dynamics and challenges.
