Abstract

This study aims to analyze the intensity of social media usage on the impulsive buying behavior of STIE Eka Prasetya students in online shopping. Social media has increasingly become an effective promotional tool, exposing students to advertisements, discounts, and influencer recommendations. The findings indicate that high social media usage intensity is closely related to students’ tendency to make spontaneous purchases. Psychological factors such as fear of missing out (FOMO) and social influences from peers further reinforce this consumptive behavior. The impact can be seen in students’ financial management, which becomes less controlled. Therefore, digital and financial literacy are needed to help students manage impulsive buying behavior in the social media era.   Keywords: Impulsive Buying, Students, Online Shopping , Social Media

Abstract

Increasingly intense business competition requires companies to implement customer retention strategies, including in the used car showroom business. This study aims to analyze the influence of customer trust and perceived value on customer loyalty at a used car showroom in Medan City. This study employs a quantitative approach with data collected through questionnaires. The sample was determined using a saturated sampling method (total sampling), in which the entire population was included as respondents. Data were analyzed using multiple linear regression with the assistance of SPSS software. The results indicate that customer trust and perceived value have a positive and significant effect on customer loyalty, both partially and simultaneously, with perceived value having a more dominant influence than customer trust. Theoretically, this study enriches the literature on relationship marketing by confirming the role of customer trust and perceived value in shaping customer loyalty in the context of the used car market. Practically, the findings provide implications for showroom managers to enhance transparency and honesty in transactions and to ensure that the benefits received by customers are proportional to the costs incurred in order to strengthen customer loyalty.
