Abstract

This study aims to analyze the relationship between marketing strategies and customer satisfaction on e-commerce platforms in Indonesia. Effective marketing strategies are essential in facing intense competition in the digital world, especially in enhancing customer satisfaction, which influences loyalty and business sustainability. This research uses a quantitative survey approach involving 100 active users of Shopee and Tokopedia platforms. Data were collected through questionnaires and analyzed using descriptive statistics, Pearson correlation, and simple linear regression. The results indicate a positive and significant relationship between marketing strategies and customer satisfaction, with a correlation value of 0.673 and a contribution of 45.3%. Digital promotions, personalized services, and loyalty programs are key factors in improving customer satisfaction. However, customer service aspects require more attention to support overall satisfaction. This study implies that e-commerce platforms must continuously develop integrated marketing strategies alongside quality service improvements to maintain and enhance customer satisfaction.

Abstract

This study explores the economic thought of Imam Al-Ghazali as presented in Ihya Ulumuddin, focusing on three main concepts: ownership, money, and market ethics. The research adopts a library research method with a qualitative approach and content analysis to examine Al-Ghazali’s perspectives in depth. The findings reveal that Al-Ghazali rejects the notion of absolute ownership of wealth, viewing it instead as a trust (amanah) from Allah that must be managed responsibly and justly. Regarding money, he defines it as a legitimate medium of exchange and strongly criticizes the practices of usury (riba) and hoarding (iktinaz), which he considers harmful to economic balance and social justice. In the realm of market ethics, Al-Ghazali emphasizes honesty, fairness, prohibition of monopoly (ihtikar), and sincere intentions in economic activities. His thoughts remain highly relevant to contemporary economic discourse, particularly in the development of a just, sustainable, and morally grounded Islamic economic system
