Ilusstration by AI

PONTIANAK – High-quality service plays a crucial role in building customer satisfaction and loyalty among passengers of PT Tri Star Melawi (TSM) Suites Class buses operating on the Pontianak–Nanga Pinoh route. A study conducted by researchers from the Faculty of Economics and Business, Muhammadiyah University of Pontianak, found that service quality has a significant direct impact on both customer satisfaction and customer loyalty. The research also revealed that customer satisfaction acts as a bridge that strengthens the relationship between service quality and loyalty. The study was published in the International Journal of Business and Applied Economics (IJBAE) in 2026.

The findings come as intercity transportation companies face increasingly intense competition and rising customer expectations. Passengers today expect not only safe transportation but also comfortable facilities, responsive service, reliable schedules, and a pleasant travel experience. Companies that fail to meet these expectations risk losing customers to competitors.

The study focused on customers of PT Tri Star Melawi (TSM) Suites Class buses serving the Pontianak–Nanga Pinoh route. Researchers analyzed the relationship between service quality, customer satisfaction, and customer loyalty using a quantitative approach and Structural Equation Modeling (SEM-PLS). The objective was to determine how service quality influences passenger behavior and long-term loyalty.

The results demonstrated that service quality significantly affects customer satisfaction and loyalty. Passengers who perceive better service are more likely to feel satisfied and continue using the company’s services in the future. Customer satisfaction was also found to play a mediating role, meaning that high service quality increases satisfaction, which in turn strengthens loyalty.

Key Findings

  • Service quality has a significant positive effect on customer satisfaction.
  • Service quality directly influences customer loyalty.
  • Customer satisfaction significantly affects customer loyalty.
  • Customer satisfaction serves as a positive and significant mediating variable between service quality and loyalty.
  • Service quality explains 39.5 percent of the variation in customer satisfaction.
  • Service quality and customer satisfaction together explain 57.6 percent of customer loyalty.
  • The findings indicate a strong relationship between service quality, satisfaction, and customer retention.

The study highlights that passengers evaluate service quality through several aspects, including vehicle comfort, staff responsiveness, reliability of travel schedules, accuracy of seat reservations, and the availability of supporting facilities. Positive experiences in these areas increase customer confidence and encourage repeat usage of the service.

Researchers found that customer satisfaction is a key factor in maintaining long-term loyalty. Satisfied passengers are more likely to recommend the service to others, continue purchasing tickets, and remain loyal even when competitors offer alternative transportation options. This makes customer satisfaction an essential strategic asset for transportation companies seeking sustainable growth.

Based on the findings, the researchers recommend that PT Tri Star Melawi continue improving service quality by maintaining fleet comfort, increasing staff responsiveness, providing clearer travel information, and minimizing delays or seat reservation errors. The company is also encouraged to improve supporting facilities such as stable Wi-Fi access, cleaner environments, more comfortable waiting areas, and enhanced customer assistance services.

The study notes that 42.4 percent of customer loyalty is influenced by factors not included in the research model. Future studies may examine additional variables such as customer experience, perceived value, company image, facility quality, and price perception to provide a more comprehensive understanding of customer loyalty in the transportation sector.

According to the researchers, maintaining high service quality is no longer optional in today’s competitive transportation industry. Service excellence not only increases customer satisfaction but also strengthens customer loyalty, helping companies build long-term relationships and improve their market position.
