Abstract

This research aims to analyze the influence of the buyer-supplier relationship, supply chain quality, and corporate social responsibility on supplier performance, as well as how supplier performance influences operational performance. This study employs a Conclusive Design with a Cross-Sectional Design type. Data is collected through Multiple Cross-Sectional methods, where data is taken one time from one group of respondents in stages. A non-probability sampling technique was applied because not all members of the population could become samples. The results of the research indicate that there is a positive influence of the buyer-supplier relationship and corporate social responsibility on supplier performance. Additionally, there is a positive influence of the buyer-supplier relationship, corporate social responsibility, and supplier performance on operational performance. However, no positive influence of supply chain quality on supplier performance or operational performance was found.

Abstract

This study aims to analyze the influence of logistics service quality on customer satisfaction and loyalty among Generation Z in the Indonesian e-commerce context. Logistics Service Quality (LSQ) is measured through six dimensions: personnel contact quality, timeliness, order condition, order discrepancy handling, operational information sharing, and empathy quality. A quantitative approach using Partial Least Squares – Structural Equation Modeling (PLS-SEM) was applied, with data collected from 155 Generation Z e-commerce users. The findings reveal that all LSQ dimensions significantly affect customer satisfaction, and satisfaction strongly influences customer loyalty (R² = 0.820). These results highlight the critical role of logistics service quality as a key determinant of satisfaction and loyalty among young digital consumers.
