Submited :22-04-2025. Accepted : 22-05-2025. Published : 22-06-2025 Abstract This study aims to analyze the role of Service Quality in increasing Customer Loyalty and Customer Retention at Tokopedia. The method used in this study is structural analysis of the model using PLS SEM to test the relationship between variables, as well as a comparison of predictions using RMSE and MAE between the two models. The results of the study indicate that Service Quality has a significant effect on Customer Loyalty . ath coefficient = 0. and Customer Retention . ath coefficient = 0. Customer Loyalty also functions as a mediator that strengthens the relationship between Service Quality and Customer Retention with a path coefficient of 0. In addition, the PLS SEM model showed better performance compared to the LM model, with lower RMSE and MAE values for most of the indicators tested. These findings indicate that Service Quality is an important factor that can increase Customer Loyalty and Retention, and indicate that PLS SEM is more effective in predicting the relationship between variables compared to LM. This study provides practical implications for Tokopedia to improve service quality in an effort to retain customers and strengthen their loyalty. Keywords : Service Quality. Customer Loyalty. Customer Retention Introduction Customer loyalty is critical to a companyAos sustainability, especially in the professional services industry, as it reflects customer satisfaction and their likelihood to continue engaging with the High levels of customer satisfaction are directly linked to increased loyalty, which is critical to long-term success (Nisa & Millati, 2. An effective customer retention strategy is essential to maintaining a loyal customer base, as loyal customers not only contribute to consistent revenue but also lower marketing costs associated with acquiring new clients (Dimitrieska, 2. Additionally, monitoring metrics such as Net Promoter Score (NPS) can provide insight into customer loyalty and areas for improvement, further supporting retention efforts (Nasr, 2. Ultimately, cultivating customer loyalty through satisfaction and retention strategies is a cost-effective approach that benefits both the company and its customers (Kasemsap, 2. In the increasingly competitive professional services industry landscape, companies must Journal of Management https://myjournal. id/index. php/JOM E-ISSN: 3026-3239 Vol. No. January - June . , pp. prioritize customer acquisition and retention. The costs associated with acquiring new customers can be much higher, often five to ten times more than retaining existing ones, making effective retention strategies critical to profitability (Zhang et al. , 2. Implementing personalized services and loyalty programs can increase customer satisfaction and loyalty, thereby reducing churn (Lianos & Sloev. Additionally, building a competitive advantage through unique offerings and exceptional service can help companies differentiate themselves and attract new clients while maintaining strong relationships with current customers (Shadrina, 2. To improve customer loyalty and retention. Tokopedia must adopt a multifaceted approach that integrates customer retention strategies, loyalty programs, and service quality improvements. Implementing personalized services and loyalty programs can significantly increase customer satisfaction and reduce acquisition costs, fostering long-term relationships with clients (Silalahi et , 2. Furthermore, focusing on improving service quality is essential, as it directly affects customer perception and can lead to increased retention rates (Nasr, 2. Additionally, leveraging digital transformation will streamline operations and improve customer experience, allowing companies to remain competitive in a rapidly evolving market (Dimitrieska, 2. To improve customer loyalty and retention, it is important to measure service quality effectively. Utilizing service quality measurement tools, such as surveys and feedback forms, allows companies to gather valuable data on customer perceptions, identifying areas for improvement (Du & Tang. By implementing service quality models such as SERVQUAL, businesses can assess the gap between customer expectations and actual service delivery, allowing for targeted improvements (Kiran & Geetha, 2. These improvements not only increase customer satisfaction but also foster loyalty through personalized service and rewards, as seen in effective customer loyalty programs (Venetis & Ghauri, 2. Methods This study uses a descriptive quantitative method. This approach aims to describe the phenomena that occur in the research object, namely the effect of service quality on Tokopedia customer loyalty.

This shows that service quality, which includes officer competence, staff politeness, and speed of service, is measured very well and can be clearly distinguished from other constructs. For Customer Loyalty and Retention, the correlation between constructs is very low, 0. between Customer Loyalty and Retention, and 0. 095 between Customer Loyalty and Service Quality. This shows that although there is a relationship between constructs, they can be clearly distinguished from each other, so that discriminant validity is maintained.

All of these values are much smaller than the threshold of 0. 90, which means there is no significant overlap between the constructs. In other words, each construct in this model can be clearly distinguished and does not interfere with each other. Model Structure Testing Table 4.

PLS SEM showed better performance than LM in terms of RMSE on most of the measured indicators. RMSE is a metric used to measure how much difference there is between the predicted value and the actual value, and the smaller the RMSE value, the better the prediction accuracy of the model. For example, for indicator KP1 . ustomer satisfactio. PLS SEM has an RMSE of 0. while LM has an RMSE of 0. This shows that PLS SEM is more accurate in predicting customer satisfaction compared to LM. Some indicators, such as PH1 . arriers to switching to other service. , show a more significant difference between the two models. On PH1. PLS SEM has an RMSE of 0. 436, while LM has an RMSE of 0. Although this difference looks small, these results still show that PLS SEM provides more accurate predictions on the indicator. The MAE test results show that PLS SEM is also superior to LM on most indicators. For example, in the KP1 indicator. PLS SEM has an MAE of 0. 297, while LM has an MAE of 0. This shows that PLS SEM has a smaller prediction error than LM. Other indicators, such as PH1, also show that PLS SEM has an MAE of 0. 352, which is smaller than LM which has an MAE of 0. This shows that PLS SEM is more accurate in predicting customer barriers to switching to other services. Conclusion The Influence of Service Quality on Customer Loyalty and Retention Service Quality has a very significant influence on Customer Loyalty with a path coefficient 969 and on Customer Retention with a path coefficient of 0. This shows that the quality of Journal of Management https://myjournal. id/index. php/JOM E-ISSN: 3026-3239 Vol. No. January - June . , pp. service provided by Tokopedia greatly influences the level of customer loyalty and retention. Indicators such as staff politeness, speed of service, and delivery security have been shown to have a major impact on influencing customer experience, which in turn influences customers' intention to continue using Tokopedia services. The Influence of Customer Loyalty on Customer Retention Customer Loyalty plays an important role in retaining customers with a path coefficient of This shows that loyal customers will tend to continue using Tokopedia services. Although the influence of loyalty on retention is smaller than the influence of service quality, loyalty remains a significant factor in maintaining long-term relationships with customers. The Mediating Role of Customer Loyalty Customer Loyalty functions as a significant mediator between Service Quality and Customer Retention, with a path coefficient of 0. This shows that customer loyalty is not only directly influenced by service quality, but also plays a role in increasing customer retention. This provides evidence that efforts to improve service quality will be more effective in retaining customers if followed by increased loyalty. Comparison of PLS SEM and LM Models Based on the results of PLS SEM and LM tests, the PLS SEM model proved to be superior in predicting indicators related to Customer Loyalty and Customer Retention. Testing using RMSE and MAE showed that PLS SEM produced smaller prediction errors than LM for most indicators. The PLS SEM model was able to provide more accurate predictions, with lower RMSE and MAE values in almost all indicators tested. Therefore. PLS SEM can be considered a more reliable and effective model for analyzing the relationship between variables in this study. References
