Abstract

The increasingly intense competition in Indonesia's e-commerce industry is compelling platforms like Tokopedia to shift from price war strategies to enhancing user experience to build long-term loyalty. This study aims to analyze the influence of User Interface (UI) and User Experience (UX) elements on User Satisfaction and User Loyalty on the Tokopedia platform. Specifically, this research also examines the mediating role of User Satisfaction in the relationship between UI/UX and User Loyalty. This research utilizes a quantitative approach with non-probability sampling through a purposive sampling technique. Data were collected via an online questionnaire distributed to 150 active Tokopedia users residing in the Jabodetabek area. The data analysis technique used is Partial Least Squares Structural Equation Modeling (PLS-SEM) with the SmartPLS 4 software. The results indicate that User Interface (UI) and User Experience (UX) have a positive and significant effect on User Satisfaction. Subsequently, User Satisfaction is also proven to have a positive and significant effect on User Loyalty. However, the key finding of this research is the insignificance of the direct effects of UI and UX on User Loyalty. Further analysis confirms the role of User Satisfaction as a full mediation variable. This indicates that the entire influence of UI and UX on User Loyalty is fully channeled through User Satisfaction. This study concludes that satisfaction is a crucial strategic bridge that must be crossed to convert a good user experience into tangible customer loyalty. The implication for Tokopedia is that investments in UI/UX improvements will not be effective in increasing loyalty if they are not accompanied by strategies that ensure these features genuinely satisfy users first.

Abstract

In the midst of increasingly fierce market competition, Nanda Gift & Souvenir Shop, as a provider of a wide range of gift products for various events, faced the challenge of increasing customer satisfaction and loyalty. The background of this problem arises from the level of customer satisfaction that is not optimal, which then has an impact on the low level of loyalty and the frequency of purchases of regular customers. This study aims to identify the factors that affect customer satisfaction at Nanda Gift & Souvenir Shop and evaluate the effectiveness of using Marketing Mix 7P to strengthen customer loyalty. The analysis was carried out by quantitative method through the distribution of questionnaires with 202 respondents, then analyzed using Structural Equation Modeling Partial Least Square (SEM-PLS). Based on the results of SEM-PLS analysis, it was found that the factors of product, price, place, promotion, labor, process, and physical evidence have a significant influence on customer satisfaction. The labor factor has the most dominant influence, followed by product, promotion, and physical evidence. Furthermore, the results of the study show that customer satisfaction has a significant and positive influence on customer loyalty. Customers who are satisfied with the products and services they receive tend to have higher levels of loyalty.

Abstract

In this study, a total of 57 transformers with a load measurement status above 95% (overload) were recorded in the year 2022 and require transformer insertions. Every year, PLN ULP Pangkalan, on average, carries out a transformer insertion program of 10 transformers due to budget limitations. With this number, it is necessary to prioritize locations based on 6 criteria: transformers with overloads >95%, maneuvering up to 50% of existing transformers, a waiting list of ready-to-connect customers, business tariff (B) customers, landowner permits required, and the need for adding new network extensions. The Analytic Hierarchy Process (AHP) method is used for weighting the criteria, followed by the Technique for Other Preference by Similarity of Ideal Solution (TOPSIS) method to determine the priority sequence of distribution transformer insertion locations. The results of the AHP method show that the highest weight is assigned to the criteria of transformers with overloads >95%, with a weight of 59.3%. The lowest weight is assigned to the criteria of having business tariff (B) customers, with a weight of 3.8%. Using the TOPSIS method, the top priority location for distribution transformer insertion is at substation PBN-0262, with a preference value of 0.721038962870702. Meanwhile, the lowest priority location is found at transformer PBH-0054, with a preference value of 0.157302058325342. The sensitivity analysis results show that the priority sequence of distribution transformer insertion locations remains consistent and does not significantly change, indicating that the TOPSIS method's prioritization results in this study are consistent.
