Abstract

This study aims to analyze the significant role of leadership, motivation, work discipline, and compensation in improving employee performance at PT Kereta Api Indonesia (Persero) Daop IV Semarang. This research adopts a quantitative associative approach, providing a clear understanding of the key factors that influence employee performance. Data were collected through a Likert-scale questionnaire, which was distributed to 80 respondents who are permanent employees of Daop IV Semarang. The data analysis was carried out using SPSS version 26, which included validity and reliability tests, as well as multiple linear regression, t-test, F-test, and the coefficient of determination (R²). The results reveal that leadership, motivation, work discipline, and compensation all have a positive and significant impact on employee performance. Among these variables, motivation was found to be the most dominant factor influencing performance. This finding suggests that fostering higher motivation and effective leadership can significantly enhance employee performance. This research provides practical implications for PT KAI management to enhance productivity through strengthening discipline culture, implementing fair compensation systems, and promoting participative leadership styles.

Abstract

Operational inefficiency remains a challenge for Indonesian branch ports, including Tanjung Emas Port in Semarang, where vessel turnaround, berth utilization, cargo handling, and inter-agency coordination affect service performance. This study aims to examine the association between berth scheduling, cargo and yard handling, and port information system digitalization with key port performance indicators, particularly vessel turnaround time, Berth Occupancy Ratio, yard occupancy ratio, and dwell time. A mixed documentary method was employed by synthesizing secondary evidence from port performance studies, DEA/SFA analyses, institutional documents, and national digitalization reports for the 2015–2025 period, with emphasis on the post-2020 operational environment. The findings show that Tanjung Emas records relatively favorable vessel turnaround performance in nominal terms, although relative efficiency results vary across DEA studies because of differences in comparator sets, model specifications, and data periods. Yard occupancy remains below the critical threshold but is projected to increase substantially by 2032. Dwell time is consistently associated with customs and quarantine documentation processes, while recent evidence identifies gate operations and stakeholder coordination as important operational constraints. Digitalization supports operational improvement, but its local evidence remains limited and still indicates risks related to system downtime, manual fallback, and interoperability gaps. The study implies that short-term improvement should prioritize parallel reform of documentary coordination and gate operations, while yard capacity and digital integration require proactive medium-term planning.
