Abstract

Transportation is one of the supporting factors for the smooth running of the economy in a country. One of the transportation is sea transportation because it is more effective and efficient. For this reason, the ship which is the main factor in the smooth operation of sea transportation must be prepared in its operation, the main thing that can support the smooth running of a ship is the smooth operation of the main engine. In general, the main engine on board the ship uses a diesel engine type, and the starting system uses compressed air where the compressed air is produced by the compressor auxiliary aircraft, so it can be said that the compressor has an important role in the operation of the ship. The compressor is one of the aircraft that is used to compress low-pressure air with higher pressure. During the operation of the main engine when the motion occurs, sometimes there are obstacles or obstacles that cause damage to the air compressor, so the compressor cannot work optimally. This results in the process of filling the main engine starting water for too long and can affect the smooth process of movement. The purpose of this study is to find out the obstacles or obstacles that can interfere with the main engine of the composer. The method used by the author in this study uses descriptive qualitative with several methods, namely, approach methods and data collection techniques. In the discussion in this study the author by finding several solutions to problems carrying out maintenance on engine room blowers and routines on the compressor as well as cleaning rust on the plunger and parts of the auto drain solenoid valve. The conclusions obtained in this study must maintain the air temperature in the engine room and always clean the high-pressure valve and low-pressure valve and pay attention to the compressor temperature so it doesn't get too hot because it can produce worse air.

Abstract

The coal transportation service industry requires companies not only to provide high-quality transportation services but also to implement business diversification strategies to enhance customer trust and satisfaction. PT Andhika Lines, as a coal transportation service provider, faces increasing competition in maintaining long-term customer relationships while improving service quality and business sustainability. This study aims to analyze the effects of Coal Transportation Services and Business Diversification on Customer Satisfaction, with Customer Trust serving as a mediating variable. This research employed a quantitative approach using a survey design involving 110 respondents who were customers of PT Andhika Lines. Respondents were selected using a purposive sampling technique. Data were collected through a five-point Likert scale questionnaire and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS). The results indicate that Coal Transportation Services have a positive and significant effect on Customer Trust (β = 0.284; t = 2.324; p = 0.010) and Customer Satisfaction (β = 0.411; t = 2.387; p = 0.009). Business Diversification also has a positive and significant effect on Customer Trust (β = 0.517; t = 4.442; p = 0.000) and Customer Satisfaction (β = 0.283; t = 2.523; p = 0.006). Furthermore, Customer Trust positively and significantly influences Customer Satisfaction (β = 0.295; t = 2.110; p = 0.018), while significantly mediating the relationship between Coal Transportation Services and Customer Satisfaction (β = 0.084; t = 1.868; p = 0.031), as well as between Business Diversification and Customer Satisfaction (β = 0.153; t = 1.821; p = 0.035). The findings reveal that Business Diversification is the most influential variable affecting Customer Trust, with a path coefficient of 0.517, while Market Expansion is the most representative dimension (loading factor = 0.962) represented by indicator X2.7 (loading factor = 0.912). Meanwhile, Empathy is the strongest dimension of the Coal Transportation Services variable (loading factor = 0.943) with indicator X1.10 (loading factor = 0.944). These findings suggest that improving customer satisfaction at PT Andhika Lines depends on expanding market coverage, delivering customer-oriented services, strengthening trust through service integrity, and maintaining long-term relationships as a source of sustainable competitive advantage.
