Abstract

This study aims to determine the effect of service quality and product variety on customer satisfaction at Ulfakue Medan. The research method used is a quantitative method with an associative approach. The sampling technique applied was non-probability sampling using purposive sampling. The population in this study consisted of all customers who had purchased products from Ulfakue Medan, with a total sample of 97 respondents. Data were analyzed using descriptive statistical analysis and multiple linear regression analysis with the assistance of SPSS software. The research findings are as follows: (1) Based on the partial test (t-test), the service quality variable (X1) obtained a t-value of 5.226, which is greater than the t-table value of 1.661, with a significance value of < 0.05. Thus, H1 is accepted, indicating that service quality has a positive and significant effect on customer satisfaction at Ulfakue Medan. The product variety variable (X2) obtained a t-value of 3.764, which is greater than the t-table value of 1.661, with a significance value of < 0.05. Therefore, H2 is accepted, indicating that product variety has a positive and significant effect on customer satisfaction. (2) Based on the simultaneous test (F-test), the F-value obtained was 86.147, which is greater than the F-table value of 3.09, with a significance value of < 0.05. This indicates that service quality and product variety simultaneously have a positive and significant effect on customer satisfaction at Ulfakue Medan. (3) Based on the coefficient of determination (R²) test, the Adjusted R Square value was 0.639, indicating that 63.9% of the variation in customer satisfaction can be explained by service quality and product variety, while the remaining 36.1% is explained by other factors not examined in this study.

Abstract

The purpose of this study is to examine and analyze the partial and simultaneous effects of Influencer Marketing and Brand Image on Purchasing Decisions of Skintific skincare products among consumers of Sociolla in Medan Baru District. Increasing competition in the skincare industry and the relatively low level of consumer purchasing decisions toward Skintific products indicate uncertainty in consumer behavior, which encourages this study to identify the main factors influencing purchasing decisions. This research uses a quantitative approach with an associative research design. Data were collected through questionnaires distributed to respondents who are Sociolla consumers in Medan Baru District. The data analysis technique used is Multiple Linear Regression Analysis preceded by Validity Tests, Reliability Tests, and Classical Assumption Tests consisting of normality, multicollinearity, and heteroscedasticity tests. The results show that Influencer Marketing and Brand Image have a positive and significant effect on Purchasing Decisions both partially and simultaneously. Based on the t-test results, each independent variable has a significant effect on Purchasing Decisions with significance values below 0.05. Furthermore, the F-test results indicate that Influencer Marketing and Brand Image simultaneously have a positive and significant effect on Purchasing Decisions. The coefficient of determination test shows that Influencer Marketing and Brand Image variables explain the variation in Purchasing Decisions in a fairly strong category. The conclusion of this study emphasizes the importance of improving marketing strategies through the use of credible influencers and strengthening brand image in order to increase consumer trust and encourage purchasing decisions of Skintific products

Abstract

This community service activity aims to provide knowledge regarding debt-related issues arising from online loans—matters that fall under civil law and frequently trigger disputes within the community, particularly among young people, often due to a lack of understanding regarding legal aspects and available dispute resolution mechanisms. Conducted at SMAN 2 Pangururan in Samosir Regency, this initiative seeks to educate participants on the legalities of online loan agreements from both civil and criminal law perspectives. The material covered includes the fundamental concepts of debt and lending, the various types of loan agreements, and the requirements for a valid contract; furthermore, participants gain an understanding of legal risks, ranging from breach of contract to potential criminal elements such as fraud or embezzlement. The outcomes of this activity serve as a foundational step toward fostering a community that is more legally aware, capable of engaging in lawful and secure transactions, and able to resolve disputes wisely in accordance with applicable regulations.
