Abstract

This study aims to analyze the effect of safety training and safety knowledge on crew competence and its implications for occupational safety on board ships at PT. Gelora Persada Makmur. This research employs a quantitative research design using a survey method with a cross-sectional approach. The population of this study consists of all ship crew members of PT. Gelora Persada Makmur, totaling 100 respondents. A saturated sampling technique was applied, in which the entire population was used as the research sample. Data were collected through a closed-ended questionnaire using a five-point Likert scale distributed online. The collected data were analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method with the assistance of SmartPLS software. The results of this study are expected to indicate that safety training and safety knowledge have a positive effect on crew competence, both directly and indirectly, and that crew competence has a positive effect on occupational safety on board. These findings are expected to serve as a basis for improving operational safety management within the company

Abstract

Ports play a critical role in national logistics systems, yet operational risks remain a major challenge, particularly in developing countries where digital transformation is still evolving. This study aims to examine the effect of digital transformation on port operational risk reduction in Indonesia, with integrated information systems, operational efficiency, and operational reliability as mediating variables. A quantitative approach was employed using questionnaire data collected from 125 port employees, analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that digital transformation has a significant positive effect on integrated information systems (β = 0.853, p < 0.001). Integrated information systems significantly influence operational efficiency (β = -0.594, p < 0.001) and operational reliability (β = -0.310, p = 0.002). Furthermore, operational efficiency significantly reduces operational risk (β = 0.355, p = 0.005), while operational reliability does not have a significant effect (p = 0.065). Mediation analysis confirms that integrated information systems and operational efficiency significantly mediate the relationship between digital transformation and operational risk reduction (β = -0.180, p = 0.007), whereas the mediation through operational reliability is not supported. These findings highlight that digital transformation contributes to reducing port operational risks primarily through improving operational efficiency, providing important implications for port management and policy development.

Abstract

This study aims to analyze the influence of vessel performance and Green shipping campaigns on the quality of the existing fleet and their implications for the satisfaction of charterers of vessels owned by PT Pertamina International Shipping. The research adopts a quantitative approach using a survey method with a cross-sectional design. The study population consists of all charterers of PT Pertamina International Shipping in 2024, totaling 33 companies, and the sample size of 117 respondents was determined using the Taro Yamane (Slovin) formula. Data were collected through questionnaires measured on a Likert scale and analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. The findings are expected to demonstrate that vessel performance and Green shipping campaigns have a positive effect on the quality of the existing fleet. Furthermore, the quality of the existing fleet is expected to have a positive influence on charterer satisfaction and to function as a mediating variable in the relationship between vessel performance, Green shipping campaigns, and the satisfaction of charterers of PT Pertamina International Shipping.
