Analisis Ketertiban Kendaraan Terhadap Kelancaran Keberangkatan Pada Kapal KMP Terubuk di Pelabuhan Tanjung Emas Semarang

Maritime safety is one of the most crucial aspects of sea transportation, largely determined by the orderliness of vehicle loading on board. This study aims to evaluate vehicle loading practices on KMP Terubuk operating on the Semarang–Kumai route by examining vehicle spacing, the use of lashing equipment, transport productivity, and ship stability based on the metacentric height (GM) value. This research employed a descriptive quantitative method using primary data obtained from field observations and secondary data from PT Dharma Lautan Utama’s operational reports. The findings reveal that the average spacing between vehicles ranged from 15 to 20 cm, which is far below the minimum standard of 30–60 cm as regulated by the Indonesian Ministry of Transportation Regulation No. 115 of 2016. Moreover, none of the vehicles were secured with lashing equipment, despite its availability on board. The transport productivity over the past five years has shown a significant increase in both passengers and vehicles; however, this growth has not been followed by adequate implementation of safety standards. Stability analysis demonstrated variations in GM values across trips, with several trips recorded below the safety threshold of 0.15 m, indicating unstable conditions. The study concludes that vehicle loading practices on KMP Terubuk do not yet comply with maritime safety regulations, thus stricter enforcement and monitoring of loading standards are urgently required.
