Abstract

PT. X focuses on warehousing logistics, transportation, and pest eradication services. In the distribution of rice, PT. X hands over to its subsidiary engaged in transportation services. The subsidiary of PT. X has problems faced, namely the number of varied delivery destinations, different requests for each customer and route determination still relying on the experience of the driver. Therefore, this research was conducted to determine the optimal route in delivery, by minimizing the total distance traveled, calculating the total minimum cost resulting from the calculation of the Tabu Search Algorithm. The results of the study, the total distance on the company's initial 4 routes amounted to 372.6 Km and the overall initial cost of 4 routes incurred by the company amounted to Rp. 1,654,244. After using the Tabu Search Algorithm, 3 new route proposals were generated amounting to 298.5 Km and the overall cost for 3 routes was Rp. 1,339,223 which means getting a distance savings of 74.1 Km and shipping cost savings of Rp. 315,021. The route results obtained using the Tabu Search Algorithm are, Route 1: (0-C4-C60) with a distance of 45.8 Km, route 2: (0-C1-0) with a distance of 85 Km, route 3: (0-C3-C5-C2-0) with a total distance of 167.7 Km.

Abstract

Digital transformation in commerce has shifted consumer behavior, making website quality and personal branding central factors in shaping customer satisfaction and purchase decisions. While prior studies often analyze these elements separately, limited research has integrated them into a unified framework to explain how digital experiences influence consumer outcomes. This study aims to examine the effects of website quality and personal branding on purchase decisions, with customer satisfaction as a mediating variable. The research adopts a quantitative approach using Partial Least Squares Structural Equation Modeling (PLS-SEM). Data were collected through an online survey of 160 respondents who had prior experience with e-commerce platforms, and the model was tested using SmartPLS with bootstrapping techniques. Findings reveal that website quality positively affects both customer satisfaction and purchase decision, while personal branding significantly influences satisfaction but does not directly impact purchase decision. Moreover, customer satisfaction strongly mediates the relationship between website quality, personal branding, and purchase decision. The study highlights the dual importance of technical excellence and authentic personal branding in fostering satisfaction and driving consumer behavior. The results provide theoretical insights for digital commerce research and practical guidance for businesses to enhance consumer trust, engagement, and purchase outcomes.

Abstract

This study aims to analyze the determinants of customer satisfaction in the e-commerce landscape by examining the roles of timeliness of delivery and online tracking. In a competitive market, customer satisfaction has become a crucial indicator of success, where logistics and supply chain management play a central role. This research proposes and tests a mediation model where online tracking is hypothesized to mediate the relationship between timeliness of delivery and customer satisfaction for Shopee Indonesia users. Using a quantitative approach, data were collected through a survey of 150 Shopee consumers in Indonesia and analyzed using Partial Least Squares - Structural Equation Modeling (PLS-SEM). The results confirm that all four proposed hypotheses were accepted. The findings indicate a significant positive influence of timeliness of delivery on both online tracking and customer satisfaction. Online tracking also has a strong positive effect on customer satisfaction. Crucially, the study validates that online tracking acts as a significant mediator in the relationship between timeliness of delivery and customer satisfaction. These findings imply that e-commerce platforms must prioritize both the reliability of delivery and the transparency of the tracking process to enhance overall customer satisfaction.

Abstract

Intense competition within the low-cost carrier (LCC) industry has shifted the strategic focus from price superiority towards enhancing service quality and passenger satisfaction. This study aims to analyze the strategic role of the operational process of baggage handling in shaping passenger satisfaction by examining the mediating role of Service Quality. Employing a quantitative approach with the Partial Least Squares Structural Equation Modeling (PLS-SEM) method, data were collected via a questionnaire from 100 respondents, who were predominantly young passengers (under 25 years old) and university students. The findings indicate that Baggage Handling has a direct, positive, and significant influence on both Service Quality and Customer Satisfaction. Furthermore, Service Quality is also proven to have a positive and significant effect on Customer Satisfaction. The most critical finding is the confirmation of the partial mediating role of Service Quality in the relationship between Baggage Handling and Customer Satisfaction. This result implies that baggage handling possesses a dual role: as a component in shaping service quality perceptions and as a direct driver of satisfaction. For LCC managers, this finding underscores the importance of managing baggage handling as a strategic service touchpoint, with practical implications including investment in automated baggage systems, real-time tracking technology, and staff training programs to effectively enhance passenger satisfaction and competitive advantage.
