This study aims to analyze the effect of facilities and service quality on customer satisfaction at Pertamina gas station Jl. Aksara, Satria Barat, Medan Perjuangan. A quantitative method using multiple linear regression was employed, with data collected through questionnaires from 30 respondents using accidental sampling. The partial test (t-test) results show that service quality has a positive and significant effect on customer satisfaction, while facilities do not show a significant individual effect. However, simultaneously (F-test), both independent variables significantly and positively influence customer satisfaction. The coefficient of determination (R²) of 60.9% indicates that customer satisfaction can be explained by the variables of facilities and service quality. This research provides recommendations for gas station management to continuously improve service quality to maintain customer satisfaction.

This study aims to analyze the effect of product arrangement on consumer purchasing decisions at Alfamidi Jl. Tuasan, Medan. Product arrangement is a crucial visual merchandising strategy in the modern retail industry to attract consumer attention and increase sales. The study used a quantitative approach with an associative method, involving 30 respondents selected through accidental sampling techniques. Data were collected using a questionnaire with a 5-point Likert scale and analyzed using simple linear regression with the help of SPSS version 25. The results showed that product arrangement had a positive and significant effect on consumer purchasing decisions with a coefficient of determination (R²) of 90.2%. The regression equation Y = 1.245 + 0.675X shows that every one unit increase in product arrangement will increase purchasing decisions by 0.675 units. The t-test produced a calculated t value of 16.071> t table 2.048 with a significance of 0.000 <0.05, confirming the research hypothesis. This finding confirms that product layout elements such as ease of access, visual appeal, and layout comfort play a vital role in influencing consumer behavior and increasing the effectiveness of retail marketing strategies.
