INTRODUCTION In this modern era, individuals or human groups experience high dependence on technology and the digital world. This creates a new paradigm shift in living patterns, including in sales transactions that no longer require direct physical meetings (Jayaputra & Kempa 2. The development of technology and the digital era has changed the way consumers fulfill their needs. International Journal of Education. Social Studies. And Management (IJESSM) Volume 4. Issue 2. June 2024 Page 720-733 Consumers now tend to switch to online purchases, which are considered more practical, fast and efficient. In addition to consumers, the increase in the portion of e-commerce use by businesses in Indonesia is also reflected in the survey results released by the Indonesian Internet Service Providers Association (APJII) in 2023, almost all businesses in Indonesia have adopted the internet as one of the tools to support The percentage of e-commerce businesses in Indonesia shows that the marketplace that is the main destination for use by businesses is Tokopedia, with a usage percentage of 73. Followed by Lazada with a usage percentage of Despite initially being the most popular, by 2023. Shopee will have to settle for third place with a usage percentage of 34. The other two marketplaces that follow are Blibli with a usage percentage of 12. 54%, and Olx with a usage percentage of 5. This survey allowed respondents to choose more than one marketplace. In the context of online shopping, e-trust refers to consumers' confidence in online sellers. In e-commerce transactions, where there is no direct interaction between buyers and sellers, consumers must rely on information and images available on websites to make purchasing decisions. Therefore, the level of consumer trust in e-commerce platforms is very important (A. Tran and Strutton There are several risks associated with e-commerce transactions, such as products that do not match the description, counterfeit products, as well as slow return processes. In addition, there are security risks such as hacking of personal data, such as consumers' names, addresses, and credit/debit card information. These risks can lead to consumer dissatisfaction and make them lose trust in ecommerce services, which in turn reduces their interest in shopping online in the future (Hadi et al. The concept of e-trust itself consists of three dimensions: ability, benevolence, and integrity (Kartono & Halilah 2. There are several consumers who show their experience in using the Tokopedia application which contains unrest and disappointment. One of them is the features in Tokopedia. Many users feel that the user interface of Tokopedia is still not working optimally. According to Sudirjo et al. state that there is a relationship between interface quality and e-satisfaction where in this study they add that by designing a very comfortable user interface and placing customer satisfaction as a top priority, with elements such as icons, colors, sizes, buttons, and languages, so that users can easily access banking services via their mobile devices. Information quality measures the quality of the output of the information system, namely the quality produced by the information system, especially in the form of reports Peter et al. Information plays an important role in the sustainability of an organization. Organizations that can International Journal of Education. Social Studies. And Management (IJESSM) Volume 4. Issue 2. June 2024 Page 720-733 manage information effectively and efficiently have an advantage over their Data leaks in e-commerce still occur frequently, and Tokopedia is ranked first in data leakage cases with a total of 91 million customer data and 7 million seller data, this can be caused by weaknesses in the personal data security system of e-commerce service users. Of all the problems above, if Tokopedia does not take the problem seriously, then consumers will be more likely to switch to other competing online shopping platforms. If many consumers feel disappointed with the shopping experience on Tokopedia, this can result in a decrease in consumer loyalty to the platform. Therefore, maintaining consumer loyalty is very important for Tokopedia, and this can also be achieved by improving user interface quality and information quality. The second factor that must be considered is information quality, which is a major concern for Tokopedia. One of the problems faced is the lack of detailed explanations about products in the online store, causing consumers to have difficulty in making choices. In addition, there is a mismatch between the products displayed on the website and the products received by consumers. According to Aziza and Hidayat . Tokopedia has implemented changes to the user interface on their online platform. This was done to evaluate how Tokopedia's interaction with users was going. According to their research, several problems arise in user interface quality at Tokopedia. One of them is the slow loading speed of Tokopedia's website, which interferes with an efficient online shopping experience. In addition, the mobile interface of Tokopedia's website is considered less minimalistic and needs to be simplified. In terms of user interface functionality. Tokopedia is still behind its competitors in the e-commerce market. Tokopedia's frequency of use and user interface complexity are also lower than Shopee. The ease of use of the Tokopedia application is also still inferior to Shopee. Lazada, and JD. ID. Tokopedia is also still inferior in terms of application feature integration when compared to Shopee. Lazada. JD. ID. Zalora, and Blibli. Tokopedia's user interface consistency is also still below Zalora and Blibli. In addition, the learning speed to use the Tokopedia application is also still lower than Lazada. Shopee, and JD. ID. Then the complexity of using the Tokopedia application is higher than Blibli. JD. ID, and Zalora. Users are also more confident using the Lazada. Shopee, and JD. applications than Tokopedia.

Thus the first hypothesis which states that E-trust has a positive and significant effect on E-satisfaction is rejected. This shows that electronic trust will not affect electronic customer satisfaction for Tokopedia users in Jabodetabek. Relationship between Information quality and E-satisfaction The information quality variable on E-satisfaction has a standardized regression weights value of -0. 439 and a P (Probabilit. 012 which is smaller 05, so information quality is stated to have a negative and significant effect on E-satisfaction. Thus the second hypothesis which states that Information quality has a positive and significant effect on E-satisfaction is rejected. This shows that information quality will not affect electronic customer satisfaction for Tokopedia users in Jabodetabek. Relationship between User interface quality and E-satisfaction The User interface quality variable on E-satisfaction has a standardized regression weights value of 0. 077 and P (Probabilit. 050, which is smaller 05, so User interface quality is stated to have a positive and significant effect on E-satisfaction. Thus the third hypothesis which states that Information quality has a positive and significant effect on E-satisfaction is accepted. This International Journal of Education. Social Studies. And Management (IJESSM) Volume 4. Issue 2. June 2024 Page 720-733 shows that User interface quality will affect electronic customer satisfaction for Tokopedia users in Jabodetabek. The results of this study are in accordance with research conducted by (Lumataw et al. , 2. on online shop consumers in the city of Manado, the results of this study indicate that interface quality, information quality, and customer service have a positive and significant impact on user satisfaction. Relationship between E-trust and Customer Loyalty The E-trust variable on Customer Loyalty has a standardized regression weights value of 0. 022 and P (Probabilit. 058 which means greater than 0. so E-trust is stated to have a positive and insignificant effect on Customer Loyalty. Thus the fifth hypothesis which states that E-trust has a positive and significant effect on Customer Loyalty is rejected. This shows that electronic trust will not affect customer loyalty for Tokopedia users in Jabodetabek. Relationship between Information quality and Customer Loyalty The Information quality variable on Customer Loyalty has a standardized regression weights value of 0. 461 and a P (Probabilit. 030 which is smaller 05, so Information quality is stated to have a positive and significant effect on Customer Loyalty. Thus the sixth hypothesis which states that Information quality has a positive and significant effect on Customer Loyalty is accepted. This shows that information quality will affect customer loyalty for Tokopedia users in Jabodetabek. The results of this study are in accordance with research conducted by Khristiano . which shows that there is a positive and significant effect of information quality on consumer loyalty. According to DeLone & McLean . , information quality measures the quality of the output of information systems, namely the quality produced by information systems, especially in the form of Information plays an important role in the sustainability of an Organizations that can manage information effectively and efficiently have an advantage over their competitors. Good and optimal information management ensures that information reaches consumers properly. In addition, information that is well conveyed by the company makes consumers feel the company's openness to the products it offers, so that consumer loyalty to the product will be well created. Several studies have been conducted on the effect of information quality on consumer loyalty. Relationship between User interface quality and Customer Loyalty The User interface quality variable on Customer Loyalty has a standardized regression weights value of 0. 068 and P (Probabilit. 032, which is smaller 05, so User interface quality is stated to have a positive and significant effect on Customer Loyalty. Thus the seventh hypothesis which states that User International Journal of Education. Social Studies. And Management (IJESSM) Volume 4. Issue 2.

The results of this study are in accordance with research conducted by AlTit . showing that UI quality has a positive influence on consumer loyalty. In addition, research by Silalahi & Sfenrianto . also supports this statement, as well as the results of Sanjaya's research . Relationship between E-trust and Customer Loyalty through E-satisfaction The variable E-trust and Customer Loyalty through the E-satisfaction variable has a probability value of 0. 55646772 or greater than 0. So the eighth hypothesis which states that E-satisfaction will have a positive and significant effect in mediating E-trust and Customer Loyalty. This means that the Esatisfaction variable is not able to mediate the relationship between the E-trust variable and the Customer Loyalty variable. This value is obtained from the results of the Sobel Test calculation. Relationship between Information quality and Customer Loyalty through Esatisfaction The Information quality variable and Customer Loyalty through the Esatisfaction variable have a probability value of 0. 14934112 or greater than 0. So the ninth hypothesis which states that E-satisfaction will have a positive and significant effect in mediating Information quality and Customer Loyalty. This means that the E-satisfaction variable is not able to mediate the relationship between the Information quality variable and the Customer Loyalty variable. This value is obtained from the results of the Sobel Test calculation. CONCLUSION The results of this study indicate that there are several rejected hypotheses, meaning that not all independent variables are able to influence the dependent variable in this study because they do not meet the requirements. The first hypothesis states that the e-trust variable (X. has a positive and significant effect on e-satisfaction (Z). This hypothesis is rejected because the results show that the e-trust variable (X. has a positive and insignificant effect on e-satisfaction (Z) for Tokopedia users in Jabodetabek. The second hypothesis states that the information quality variable (X. has a positive and significant effect on e-satisfaction (Z). This hypothesis is rejected because based on the results of the study, it shows that the information quality variable (X. has a negative and significant effect on e-satisfaction (Z) for Tokopedia users in Jabodetabek.

The fifth hypothesis states that the e-trust variable (X. has a positive and significant effect on e-customer loyalty (Y). This hypothesis is rejected because based on the results of the study, it shows that the e-trust variable (X. has a positive and insignificant effect on e-customer loyalty (Y) among Tokopedia users in Jabodetabek. The sixth hypothesis states that the information quality variable (X. has a positive and significant effect on e-customer loyalty (Y). This hypothesis is accepted because based on the results of the study, it shows that the information quality variable (X. has a positive and significant effect on e-customer loyalty (Y) for Tokopedia users in Jabodetabek. The seventh hypothesis states that the user interface quality variable (X. has a positive and significant effect on ecustomer loyalty (Y). This hypothesis is accepted because based on the results of the study, it shows that the user interface quality variable (X. has a positive and significant effect on e-customer loyalty (Y) among Tokopedia users in Jabodetabek. The eighth hypothesis states that the E-satisfaction variable (Z) will have a positive and significant effect in mediating E-trust (X. and e-loyalty (Y). This hypothesis is rejected because based on the results of the study, it shows that the E-satisfaction (Z) variable is unable to mediate E-trust (X. and e-loyalty (Y) for Tokopedia users in Jabodetabek. The ninth hypothesis states that the Esatisfaction variable (Z) will have a positive and significant effect in mediating Information quality (X. and e-loyalty (Y). This hypothesis is rejected because based on the results of the study, it shows that the E-satisfaction (Z) variable is unable to mediate Information quality (X. and e-loyalty (Y) for Tokopedia users in Jabodetabek. The tenth hypothesis states that the E-satisfaction variable (Z) will have a positive and significant effect in mediating User interface quality (X. and e-loyalty (Y).
