The Influence of Perceived Ease of Use, Consumer Trust, and After-Sales Service on Purchase Intention Through Perceived Usefulness (on the Purchase of Epson Brand Projectors)

Abstract

Technological developments increase the need for projectors as supporting devices for educational, business, and entertainment activities, so that the factors that shape purchasing intention need to be understood. This study aims to analyze the effect of Perceived Ease of Use, Consumer Trust, and After-Sales Service on Purchase Intention through Perceived Usefulness on the purchase of Epson brand projectors at CV Intimediatama. The study uses an explanatory quantitative approach. The study population is consumers who have purchased Epson projectors at CV Intimediatama with an unknown number, while a sample of 96 respondents was determined using the Lemeshow formula and purposive sampling technique. Data were collected through a closed questionnaire with a Likert scale of 1 to 5 and analyzed using PLS-SEM with the help of SmartPLS through evaluation of the outer model, inner model, hypothesis testing, and bootstrapping. The results showed that Perceived Ease of Use and Consumer Trust have a positive and significant effect on Perceived Usefulness. After-Sales Service has no effect on Perceived Usefulness. After-Sales Service and Perceived Usefulness had a positive and significant effect on Purchase Intention, while Perceived Ease of Use and Consumer Trust did not. Perceived Usefulness also did not mediate these three relationships. In conclusion, Purchase Intention was more strongly influenced by After-Sales Service and directly perceived product benefits
