The purpose of this study was to determine the effect of ship worthiness and seafarers' skills on improving ship operational performance through minimum service standards. Some early indications found in the field, such as the low performance of ship maintenance by procedures, and the obstacles in implementing the ship maintenance plan due to the inefficiency of the ship's operating schedule. This study uses Path Analysis with Path Coefficients Sub Structure 1 and Sub Structure 2. The test method used for the direct effect is the regression method while the indirect effect is the Sobel test. The number of samples is 80 respondents from national shipping companies, from various types of ships, namely, crew boats, patrol boats, utility boats, supply vessels, and anchor handling towing supply. The results of the study indicate that there is a positive and significant effect of seaworthiness and seafarers' skills on increasing ship operational performance, directly or indirectly through minimum service standards. The minimum service standard variable can mediate the indirect effect of the seafarers' skill and ship worthiness variables on the operational performance of the ship. To meet the growing customer satisfaction as the consequences of tight competition, it is necessary to improve the quality of the fleet where durability, cleanliness of the fleet, and safety facilities in the fleet are expected to provide a high guarantee for safety.

This study investigated the impact of social media marketing on Garuda Indonesia's airline customers' brand equity (awareness, image, and loyalty) and online word-of-mouth during the epidemic (E-WOM). In part of the study, 100 frequent Instagram users and passengers on Garuda Indonesia aircraft were questioned or given questionnaires. The data was processed and analyzed by SEM-PLS and the SmartPLS 3.0 software. The findings of the study indicate that social media marketing increases brand recognition, brand image, and brand loyalty. Brand loyalty or reputation has one significant impact on e-WOM as well. While brand recognition has nothing to do with E-WOM. Furthermore, the results of this research definitely point to the importance of the impact on E-WOM while brand recognition has no impact on E-WOM. The study's conclusions also highlight the importance of mediating variables including brand awareness, brand image, and brand loyalty. This study can prove that almost all moderating effect variables are involved in mediating social media marketing on Garuda Indonesia's e-WOM airline, except the brand awareness variable, which has no indirect effect or has no impact on the relationship between social media marketing and E-WOM. The results of this study should be relevant to a social media strategy, particularly for Garuda Indonesia Airlines.
