Abstract

This study aims to analyze the influence of terminal location and accessibility on safety/security through service reliability among logistics companies operating at Tanah Merdeka Terminal, North Jakarta. A quantitative approach was employed using a survey method. The study population consisted of approximately 40 logistics companies in the research area, all of which were included in the sample using saturated sampling technique. Data collection was conducted through questionnaire distribution between March and June 2025. Data analysis was carried out using Structural Equation Modeling based on Partial Least Squares (PLS-SEM) with the assistance of SmartPLS version 4.1 software. The results indicate that service reliability has a significant influence on safety/security. Additionally, terminal location indirectly affects safety/security through service reliability. However, accessibility was found to have no significant direct or indirect effect on service reliability and safety/security. These findings highlight the critical role of enhancing service reliability as a key factor in improving logistics safety and security.

Abstract

This study investigates the effects of on-time performance, safety, comfort, and accessibility on electronic Word of Mouth (e-WOM) through passenger satisfaction at Cililitan Bus Terminal. Using a quantitative approach, data were collected from 270 respondents through a structured questionnaire and analyzed with Partial Least Squares Structural Equation Modeling (PLS-SEM). The results show that on-time performance, comfort, and accessibility significantly influence passenger satisfaction, while safety does not. Furthermore, on-time performance and comfort have a direct and significant impact on e-WOM, whereas safety and accessibility do not. Passenger satisfaction serves as a mediating variable, strengthening the relationship between service quality factors and e-WOM. These findings highlight the importance of punctuality, comfort, and ease of access in enhancing passenger experience and fostering loyalty through positive word of mouth. Terminal operators are encouraged to focus on improving these aspects to ensure sustainable service quality and customer engagement.

Abstract

This study aims to analyze the impact of service innovation, pricing, and trust on ticket purchase retention for intercity and interprovincial (AKAP) buses at PO Sinar Jaya. Despite the increasing number of passengers, ticket purchase retention remains suboptimal, and the load factor is only 50%, far below the ideal standard of 70%. This phenomenon suggests that factors beyond passenger volume, such as service innovation and pricing policies, play a crucial role in influencing customer loyalty. The research employs a descriptive method with a quantitative approach. The study population consists of all PO Sinar Jaya passengers in 2023, totaling 5,635,602 passengers. The sampling technique used is Random Purposive Sam-pling. The sample size is determined using Hair’s (2020) formula, based on the number of research indicators. Data was collected through questionnaires, and analysis was conducted using the Structural Equation Modeling (SEM) method with SmartPLS software. The results indicate that service innovation positively influences trust and ticket purchase retention, whereas pricing does not significantly impact trust but positively affects ticket purchase retention. Additionally, trust plays a crucial role in enhancing purchase retention. The findings highlight the importance of service innovation and competitive pricing strategies in improving customer loyalty at PO Sinar Jaya.
