INTRODUCTION
Nowadays, free trade is increasingly becoming an economic concept adopted by many countries around the world including Indonesia. According to (Prentice, Dominique Lopes, & Wang, 2020), free trade can be explained as the sale of products between countries without import and export taxes or other trade barriers. With the introduction of free trade in Indonesia, the flow of goods into and out of Indonesia is expected to increase dramatically. Therefore, efficient and efficient transportation methods are very important to minimize the cost of transportation operations. Ocean freight is one of the relatively inexpensive modes of transportation that can support import and export activities (Teravaninthorn & Raballand, 2009).
To support and protect the domestic shipping industry, the Indonesian government took decisive steps to implement the principles of cabotage in 2005. (Warsilan, 2018) According to the policy only allows Indonesian-flagged vessels to sail and distribute cargo in Indonesian waters. The regulation also stipulates that Indonesian-flagged vessels must be at least 51 percent owned by Indonesian parties. Eight years later, in 2013, the implementation of the principles of cabotage is exciting domestic shipping industry. This amazing achievement can be seen from the significant increase in the market share of Inland freight volume increased by 54% or about 101.3 million tons from 187.6 million tons in 2004 and 98.85% or about 350.93 million tons from 355 tons (Minot et al., 2019).
The number of national fleets increased sharply from 6,041 vehicles or 5.67 million tons gross tons in 2004 to 12,774 vehicles or about 18.2 million tons in 2013 (Wahyudi, 2021) These outstanding achievements reflect the bright future of my country's shipping industry. The domestic shipping industry is expected to grow by 6-7% in 2014 (Octaviannand, Pandjaitan, & Kuswanto, 2017). Given the importance of this policy to the national economy, the government is also expected to continue to implement the principle of cabotage. In addition, Indonesia's economy is expected to grow by more than 5% in 2015, which means that the overall business environment will remain good in 2015, which is bound to have a positive impact on the Indonesian shipping industry (Endang, 2021).
With the above-mentioned development of the shipping industry, the demand for shipping services will continue. This forces shipping companies to compete for customers. (Viederyte & Didziokas, 2014). As the shipping industry provides services, the existing competition is to provide satisfactory services to consumers by competing with each other and to provide information to customers through interpersonal business activities. The performance of a shipping company determines whether the company is competitive in the world market. A simple requirement that shipping companies must meet is that the company can provide services based on the needs and desires of the community (Griffith, 2019). activities related to the strategic value of the company's customer information on its business activities (Daniri, 2008).
As part of the marketing and sales team, the company has several dedicated customer service representatives to focus on one or a few key clients, in order to meet the needs of these clients (Notteboom, 2004). PT Buana Listya Tama always prioritizes quality service, by trying to provide services that exceed customer expectations. However, in reality the efforts made by PT Buana Listya Tama so far have not had the results as expected (Table 1). Given the unexpected sales growth of PT Buana Listya Tama, the year-on-year decline in sales levels, and the rising sales levels, reasonable efforts are required to identify new market opportunities to increase sales levels. New market opportunities and maximum service to retain existing customers. When the community as a customer is satisfied with the company's services, they maintain their loyalty to the company and do not rule out the possibility of influencing others using PT Buana Listya Tama's shipbroking services (Tukker & Tischner, 2017).
This study aims to analyze the relationship between ship agency service quality, interpersonal communication and user satisfaction at PT Buana Listya Tama, either partially or simultaneously.

METHOD RESEARCH
Basically this section describes the implementation and service methods. The description of the implementation of the activity includes the location, time, participant background, and the number of participants. Meanwhile, the description of the activity method includes the methods and materials presented. Choose one or a combination of several activity methods, including: (1) training / training related to goods and services, diffusion of science and technology, substitution of science and technology (renewable science and technology), or simulation of science and technology; (2) Continuous education; (3) awareness / increased understanding of a problem; (4) consultation / mentoring / mediation. It is best to avoid organizing the writing into "sub-headings" in this section (Sunyoto, 2013). This study uses a quantitative survey method. Data Analysis with Hypothesis Testing, Correlation Test and Multiple Linear Regression Test. the tool used to analyze the data is SPSS version 21

RESULT AND DISCUSSION
Based on multiple regression calculations between Service Quality (X1), Interpersonal Communication (X2), and Satisfaction (Y) with the help of the SPSS program in the calculation, the following results can be obtained:  The regression results above are stated in the following formula: Satisfaction = 11.901 + 0.677 X1 + 0.820 X2 With the following explanation; a constant of 11.901 means that if the variable quality of service and interpersonal communication is 0, then the satisfaction value is positive at 11.901; The regression coefficient for the service quality variable is 0.677, meaning that if the service quality increases by 1, then satisfaction will increase by 0.677. The positive coefficient means that there is a unidirectional relationship between service quality and satisfactionso that if there is an increase in service quality, it will also increase the satisfaction of service users at Buana Listya Tama; The regression coefficient for interpersonal communication variables is 0.820, meaning that if interpersonal communication increases by 1, then satisfaction will increase by 0.820.
The positive coefficient means that there is a unidirectional relationship between interpersonal communication and satisfaction, so if there is an increase in interpersonal communication, it will also increase the satisfaction of service users at Buana Listya Tama.
The coefficient of determination test is used to calculate the effect of the independent variable on the dependent variable by using the R square number (number squared correlation) or the coefficient of determination in the model summary table in the regression test results with the SPSS program, as follows: The t-test was conducted to determine the correlation of the independent variables (quality of service and interpersonal communication) partially to the dependent variable (Y). From the results of the regression test the output is presented as follows:  Table 3 shows the value of t arithmetic > t table (4.905 > 1.998) for the X1 variable, then Ho is rejected. This means that service quality is significantly correlated with service user satisfaction at PT Buana Listya Tama. Table 4 shows the value of t arithmetic > t table (6.108 > 1.998) for the X2 variable, then Ho is rejected, meaning that interpersonal communication is significantly correlated with service user satisfaction at PT Buana Listya Tama.
The F test was conducted to determine whether the independent variables (Quality of Service and Interpersonal Communication) were significantly correlated with the dependent variable (Satisfaction). Significant means that the relationship that occurs can apply to the population (can be generalized). From the results of the regression analysis output, it can be seen that the F value is shown in table 4 below:  study also showed that the increase or decrease in customer satisfaction during the study period was also partly related to interpersonal communication variables. This is based on the results of the t-test, which concludes that the tcount is greater than the t-table, which is 6.108 compared to t-table = 1,998. Finally, the results of this study concluded that the increase or decrease in customer satisfaction during the study period was related to service quality and interpersonal communication variables. This is based on the results of the F-test, which concludes that the F-number is greater than the predetermined F-table, which is an F-number of 90,839. > F Table 2.75. Measured by the coefficient of determination, service quality and interpersonal communication contributed 74.9% to customer satisfaction, while other unexamined variables contributed 25.1%.

CONCLUSION
Based on the data analysis results of all the data received, it can be concluded that the respondents' average score for the service quality variable (X1) was 4.17, while the respondents' average score for the interpersonal communication variable was 1.4.17 (X2) The average rating is 4.12; the average customer satisfaction rate is 4.08. These three variables have mean values in the consent category. Therefore, it can be said that PT Buana Listya Tama's service quality, interpersonal communication and customer satisfaction are all in a good category.
From the results of hypothesis testing, this study supports three hypotheses, namely interpersonal communication and service quality variables, which are partially or simultaneously significantly correlated with customer satisfaction variables. The quality of service variable is positively and significantly correlated with t-count 4,905 and greater than t-table 1,998, so it can be concluded that H0 is rejected and Ha is accepted. Interpersonal communication variables are also positively correlated with customer satisfaction, with a tcount value of 6.108 and a t-table greater than 1.998, so H0 can be rejected in favor of Ha.
The coefficient of determination (R Sguare) value between variables was 0.749 or 74.9%. The contribution rate of service quality and interpersonal communication variables to customer satisfaction is 74.9%. The rest is simply explained by other factors outside the research model. It is expected that the application of the results of this study will have an
