Abstract

This study aims to analyze the influence of product quality, price, and promotion on customer satisfaction with Sambal Nagih products in Pontianak City. This research uses an associative quantitative approach with a total of 100 respondents selected using a purposive sampling technique. Data were collected through interviews and questionnaires. The results of multiple linear regression analysis show the equation Y = 1.061 + 0.243X₁ + 0.225X₂ + 0.203X₃, with a correlation coefficient (R) of 0.697, which indicates a strong relationship. The coefficient of determination (R²) value of 48.6% indicates that the variation in customer satisfaction can be explained by product quality, price, and promotion, while the remaining percentage is influenced by other variables outside the model. The F-test results show that product quality, price, and promotion simultaneously have a positive and significant effect on customer satisfaction. The partial t-test results also show that the three independent variables individually have a positive and significant effect. In conclusion, product quality, price, and promotion have been proven to contribute to increasing Sambal Nagih customer satisfaction. This study recommends the need for product innovation improvement, competitive pricing, and more attractive promotions to maintain Sambal Nagih’s competitiveness. Future research is expected to add other variables, such as customer loyalty, to obtain more comprehensive results.

Abstract

This study aims to analyze the influence of product quality, price perception, and service quality on customer satisfaction at Pondok Poteng Restaurant in Singkawang City. This research uses an associative quantitative approach with a total of 100 respondents selected through purposive sampling. Data were collected through questionnaires and interviews. The results of multiple linear regression analysis show the equation Y = 1.018 + 0.219X₁ + 0.238X₂ + 0.223X₃ with a correlation coefficient (R) of 0.712, indicating a strong relationship. The coefficient of determination (R²) is 50.6%, which means that 50.6% of the variation in customer satisfaction is influenced by product quality, price perception, and service quality. The F test shows an F calculated value of 32.842, which is greater than the F table value of 2.70, with a significance value of 0.000 < 0.05, meaning that the independent variables simultaneously have a positive and significant effect. The partial t test also shows that each variable product quality, price perception, and service quality have a positive and significant effect on customer satisfaction. In conclusion, these three variables have a real contribution to increasing customer satisfaction. This study recommends strengthening product quality standards, adjusting pricing strategies to be more competitive, and improving service management to maintain customer loyalty. Future research is expected to add other variables, such as promotion or brand image, so that the results can be more comprehensive.

Abstract

This study aims to analyze the influence of electronic service quality and perceived value on customer loyalty of Vidio.com in Pontianak City, with customer satisfaction as an intervening variable. The research employs a quantitative approach with an associative research design. The population of this study consists of residents of Pontianak City who have used Vidio.com services. The sample was determined to be 100 respondents using purposive sampling techniques, with criteria including a minimum age of 18 years and having used Vidio.com at least once. Data were collected using questionnaires and analyzed using SEM-PLS through SmartPLS 3 software. Evaluation of the measurement model (outer model) was conducted through convergent and discriminant validity tests, Average Variance Extracted (AVE) values, and construct reliability. Evaluation of the structural model (inner model) was performed using R-square values and testing of direct and indirect effects through bootstrapping. The results show that electronic service quality does not have a significant effect on satisfaction, while perceived value has a positive and significant effect on satisfaction. Satisfaction has a positive and significant effect on customer loyalty. Furthermore, electronic service quality and perceived value do not have a direct effect on loyalty. In mediation testing, satisfaction does not mediate the effect of electronic service quality on loyalty, but it significantly mediates the effect of perceived value on loyalty.

Abstract

This study aims to analyze the effect of ease of use and perceived value on user loyalty with user satisfaction as a mediating variable in the use of the DANA e-wallet in Singkawang City. This study uses a quantitative approach with an associative method. The research population includes all DANA e-wallet users domiciled in Singkawang City, with a sample of 100 respondents determined through purposive sampling. Data analysis was conducted using Structural Equation Modeling (SEM) based on Partial Least Squares with the assistance of SmartPLS version 3 software. Model testing includes evaluation of the outer model and inner model, which includes convergent and discriminant validity tests, the Average Variance Extracted (AVE) value, and reliability testing. Meanwhile, inner model testing was carried out through analysis of R-square values, direct effects, and indirect effects. The results show that ease of use and perceived value are able to explain the variability of user satisfaction by 73.0%, while the remaining 27.0% is influenced by other factors outside the research model. Furthermore, based on the R-square value of the user loyalty variable, it is known that the combination of ease of use, perceived value, and user satisfaction contributes 55.1%, while the other 44.9% is influenced by other variables not examined. The direct effect test results show that ease of use and perceived value have a positive and significant effect on user satisfaction, and user satisfaction, ease of use, and perceived value have a direct effect on user loyalty. In addition, the results of the indirect effect test prove that user satisfaction acts as a mediating variable in the relationship between ease of use and perceived value on the loyalty of users of the DANA e-wallet.
