Abstract

This study investigates the influence of perceived Usefulness and ease of use on digital payment efficiency among university students who utilize QRIS in Indonesia. Positioned within the Technology Acceptance Model, the study aims to assess the post-adoption impact of these two constructs on transaction efficiency. A quantitative method was employed using Structural Equation Modeling (SEM) with SmartPLS 0.4 on a sample of 100 students. The instrument's reliability and validity were confirmed through outer loading, Cronbach's alpha, composite reliability, and AVE tests. Results indicate that perceived Usefulness has a more substantial effect (β = 0.546, p < 0.001) than ease of use (β = 0.335, p < 0.01) in enhancing payment efficiency. The model achieved a good fit (SRMR = 0.069; NFI = 0.796) and an R² of 0.716 for digital payment efficiency. These findings highlight the behavioral mechanisms through which students perceive payment efficiency and underscore the importance of utility perceptions in driving system performance. The article discusses these findings using theoretical reasoning from TAM and empirical evidence in fintech behavior studies to demonstrate how QRIS adoption can be optimized among digital-native users

Abstract

This study analyzes the effects of marketing strategy and the ease of use of the MyPertamina application on purchasing decisions for Pertamax, with customer satisfaction as a mediating variable in Medan City. A quantitative approach was employed using SEM-PLS with a sample of 100 MyPertamina users. The results indicate that marketing strategy has a positive and significant effect on customer satisfaction and on purchasing decisions. The ease of use of the application has a positive and significant effect on customer satisfaction, but it does not directly affect purchasing decisions. Customer satisfaction has a positive and significant effect on purchasing decisions and mediates the effects of marketing strategy and ease of use on purchasing decisions. These findings emphasize that improving purchasing decisions is more effectively achieved by strengthening customer satisfaction, both through marketing strategies and by enhancing the application’s ease of use. Practically, PT Pertamina should optimize its digital marketing and develop a MyPertamina application that is simple, reliable, and user-experience oriented to encourage Pertamax purchases.

Abstract

This study aims to examine the effect of attendance, e-performance application, and employee income supplementation on employee performance. Quantitative paradigms and deductive reasoning were used in this study, developing a conceptual model based on previous empirical results and theoretical studies, which was then tested using structural equation modeling. The population in this study was the entire Public Works and Spatial Planning Agency of North Sumatra Province, totaling 985 employees. The sample was determined using the Slovin formula, resulting in a total of 169 respondents. Data were collected using a questionnaire in the form of a Google Form. The data collected in this study were analyzed using the PLS-SEM-based structural equation modeling method, which is a form of structural modeling to explain the patterns of relationships between variables, both directly and partially, and also to test the conceptual framework proposed in the study. The results showed that all proposed hypotheses were accepted. Attendance, e-performance, and employee supplementary income significantly impact employee performance at the Public Works and Spatial Planning Agency of North Sumatra Province, directly or partially.

Abstract

This study aims to analyze competitive advantage development strategies to improve customer satisfaction in the logistics business in Indonesia. Increasingly fierce competition demands logistics companies to be able to create superior value through service quality and customer value. This study uses a quantitative approach with a survey method of logistics service users, with data collection through an online questionnaire. The variables studied include service quality, customer value, competitive advantage, and customer satisfaction. Data analysis was conducted using the Structural Equation Modeling (SEM) method to test the relationship between variables. The results show that service quality and customer value have a positive and significant effect on competitive advantage. In addition, service quality, customer value, and competitive advantage also have a positive and significant effect on customer satisfaction. These findings indicate that improving service quality and creating customer value can effectively enhance a company's competitive advantage. A strong competitive advantage will impact on increasing customer satisfaction with the services received. Therefore, logistics companies need to continue to develop strategies that focus on improving service quality and customer value to maintain competitiveness and increase customer satisfaction sustainably.
