Abstract

(General Background) The increasing competition in Indonesia’s retail sector highlights the critical role of service quality in influencing consumer purchasing behavior. (Specific Background) Faiz Plastic Store Sidoarjo, a retailer of household and packaging products, has experienced a decline in sales performance, allegedly due to deteriorating service quality that affects consumer retention. (Knowledge Gap) Previous studies have confirmed the impact of service quality on purchasing behavior, yet empirical evidence regarding its structural influence on purchase decisions, repeat purchases, and customer loyalty in small-scale retail settings remains limited. (Aims) This study aims to analyze the causal relationship between service quality (Servqual), purchase decisions, repeat purchases, and customer loyalty using Structural Equation Modeling (SEM). (Results) Findings reveal that service quality significantly influences purchase decisions, but purchase decisions do not significantly affect repeat purchases, while repeat purchases have a strong positive effect on customer loyalty. (Novelty) The study develops a structural model that clarifies the indirect mechanism linking Servqual dimensions to loyalty through behavioral intentions. (Implications) The results emphasize that maintaining high service quality should be complemented with loyalty programs, digital engagement, and online ordering systems to ensure customer retention and business sustainability. Highlights:  Service quality significantly shapes initial purchasing behavior. Repeat purchases serve as the main driver of customer loyalty. Loyalty programs and digital engagement enhance long-term retention. Keywords: Servqual, Purchase Decision, Repeat Purchase, Customer Loyalty, Retail Service Quality

Abstract

General Background: Rapid technological advancements have transformed consumer behavior, especially in the smartphone industry, where performance, design, and innovation are key competitive aspects. Specific Background: Samsung, as a leading smartphone brand, continuously enhances its product quality and brand image to sustain customer loyalty, particularly with flagship models such as the Galaxy S25 Ultra. Knowledge Gap: Despite extensive studies on purchasing behavior, limited research integrates product quality, brand image, and purchase decisions as mediating factors influencing repurchase intention in premium smartphone contexts. Aims: This study investigates the effect of product quality and brand image on repurchase intention, mediated by purchase decision, among Samsung Galaxy S25 Ultra users in Indonesia. Results: Using Structural Equation Modeling (SEM) with AMOS on 100 respondents, findings reveal that brand image significantly influences purchase decision and repurchase intention, while product quality significantly impacts repurchase but not purchase decision. Purchase decision does not mediate the relationship effectively. Novelty: The integration of SEM-based mediation analysis provides a comprehensive understanding of causal relationships among variables in digital-era consumer behavior. Implications: Strengthening brand perception and maintaining consistent product quality are essential strategies for fostering long-term customer loyalty in competitive smartphone markets. Highlights: Brand image significantly drives both purchase and repurchase behavior. Product quality impacts repurchase but not initial purchase decisions. Purchase decision shows weak mediation between quality, image, and repurchase. Keywords: Product Quality, Brand Image, Purchase Decision, Repurchase Intention, SEM-AMOS
