The development of digital technology has fueled the rise of online buying and selling practices through marketplaces and social media, including among students. This convenience is not without legal and ethical issues, such as misdescribed goods, fraud, and the weakening of consumers' position compared to businesses. This research uses a normative method with a qualitative approach through literature review, regulatory analysis, and interviews with UNIMED Civics students to examine consumer protection from the perspective of positive law and Islamic law. Theoretical studies indicate that Law Number 8 of 1999 concerning Consumer Protection (UUPK) affirms consumers' rights to security, comfort, accurate information, and opens up opportunities, although its implementation remains hampered by low legal awareness. Meanwhile, muamalah jurisprudence affirms the validity of a sale and purchase contract if it meets the pillars and conditions, and upholds the values ​​of honesty (ṣidq), justice (‘adl), trustworthiness, and the prohibition of gharar and tadlis. The results of the study indicate that violations of online transactions not only violate the UUPK but also undermine Islamic business ethics. Therefore, the integration of Islamic law and positive law is necessary to strengthen digital consumer protection in a fair and beneficial manner.

Overall, product quality plays a crucial role in shaping consumer choices regarding Wardah lip cream, surpassing the effects of brand familiarity or promotional efforts through influencers

The rapid development of digital technology has significantly transformed commercial activities, particularly through the emergence of marketplaces as platforms for online transactions. The vast number of products available in a marketplace often creates difficulties for users in finding items that suit their needs and preferences. To address this challenge, a recommendation system is required to provide personalized and relevant product suggestions. This study discusses the implementation of a product recommendation system in a marketplace using the Collaborative Filtering method. This method works by leveraging information from users’ previous behavior, such as purchase history, ratings, and similarity of preferences with other users, to generate more accurate product recommendations. The Collaborative Filtering approach has proven effective in identifying user preference patterns based on relationships between users as well as between items. This study employs user interaction data such as ratings and shopping activities as the processing foundation. The process involves data collection, preprocessing, calculation of similarity between users or products, and generating recommendation lists. The results indicate that this method enhances the shopping experience by providing relevant product suggestions tailored to user interests, thereby increasing customer satisfaction and potentially improving sales performance in the marketplace. Thus, the application of a Collaborative Filtering-based recommendation system not only simplifies product discovery for users but also offers strategic advantages for marketplace operators in digital business competition

This study examines the influence of online customer reviews and customer satisfaction on repurchase intention for Erigo fashion products sold on Shopee. The research is motivated by the rapid growth of local fashion sales on e-commerce platforms, yet the Erigo brand shows relatively low repurchase intention despite receiving many positive ratings. This gap between consumer expectations and actual experiences highlights the importance of satisfaction in driving loyalty. The study adopts a quantitative approach with descriptive and verificative methods. The population consists of Shopee consumers who have purchased Erigo products, with purposive sampling applied. A total of 362 valid responses were analyzed after outlier removal from 385 initial respondents. Descriptive results indicate that online customer reviews are categorized as very high (4.40), customer satisfaction as high (4.08), and repurchase intention as good (3.95). The findings show that online customer reviews contribute 47.70%, customer satisfaction 57.10%, and both variables jointly 59.60% to repurchase intention. Hypothesis testing confirms significant partial and simultaneous effects of both predictors on repurchase intention.

The development of the internet in Indonesia has opened up numerous opportunities, including in the field of online commerce. One widely used feature in online transactions is the "Paylater" system, as implemented by Shopee through its Shopee Paylater service. This feature allows users to purchase goods now and pay for them later, with relatively low interest rates. This study aims to examine the regulations and implementation of Shopee Paylater, as well as the legal protection available to consumers in cases of default or issues with the service. The study refers to the Indonesian Civil Code, Law No. 8 of 1999 on Consumer Protection, and the Financial Services Authority Regulation (POJK) No. 77/POJK.01/2016 on Information Technology-Based Lending Services. The research findings indicate that Shopee Paylater users are bound by a standard agreement with PT. Commerce Finance during the purchasing process. Shopee is responsible for protecting consumers in accordance with applicable regulations, but breaches related to network security can pose risks to consumers. In addition, while the service facilitates easier access to goods and services for users, it is crucial that consumers fully understand the terms and conditions of the service, including the consequences of late payments. The study also emphasizes the need for clearer and more comprehensive consumer protection regulations, especially in light of the rapid growth of digital financial services. This research highlights the importance of adequate legal protection for users of Paylater services to ensure their rights are safeguarded in the evolving digital economy.

The growth of e-commerce in Indonesia has changed consumption patterns, especially in the online purchase of skincare products. Shopee, as the largest marketplace, has become the main platform for brands such as Skintific, which has achieved high sales. This phenomenon shows the support of online consumer reviews (Electronic Word of Mouth/E-WOM) and digital shopping experiences (Online Customer Experience/OCE). This study aims to examine the influence of E-WOM and OCE on purchasing decisions for Skintific products on Shopee. This study used a quantitative method with an associative approach. The research sample consisted of 97 respondents obtained through purposive sampling. Data analysis was performed through validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination (R²). The results of the study indicate that E-WOM has a positive and significant effect on purchasing decisions (calculated t = 5.209 > table t = 1.986; sig. <.001). OCE also has a positive and significant effect on purchasing decisions (t-count = 7.605 > t-table = 1.986; sig. <.001). Simultaneously, both independent variables have a significant effect on purchasing decisions (F-count = 101.366 > f-table = 3.09; sig. <.001). The coefficient of determination (R²) value of 0.683 indicates that 68.3% of the variation in purchase decisions can be explained by E-WOM and OCE, while the remaining 31.7% is influenced by other factors outside the research model. These findings confirm that consumer online reviews and positive online shopping experiences play an important role in increasing purchase decisions for Skintific products on Shopee.

This study employs a qualitative library research method with the aim of analyzing fiqh muamalah in the practice of online buying and selling transactions from the perspective of Islamic law and sharia. The development of digital technology has given rise to various new models of transactions that require Islamic law to remain adaptive and relevant. Online trade is one form of contemporary muamalah that raises several issues, such as the validity of contracts, price transparency, clarity of goods, and the potential for fraud. In fiqh muamalah, the validity of a sale and purchase contract is determined by the fulfillment of its pillars and conditions, namely the presence of contracting parties, a clearly defined object of transaction, and a legitimate agreement. The findings indicate that online buying and selling transactions are valid as long as they comply with sharia principles such as justice, transparency of information, clarity of goods, and the absence of gharar (uncertainty), maysir (gambling), or riba (usury). Thus, Islamic law does not reject technological innovation as long as the substance of the contract remains in line with sharia. This research emphasizes that fiqh muamalah is capable of providing practical and relevant solutions in addressing the challenges of the modern digital economy.

Furthermore, sellers are encouraged to apply urgency-based strategies, such as limited-time offers, to increase consumer purchase intention.

The increasing prevalence of online customer reviews has made them a critical component in consumer decision-making processes, particularly in the food and beverage sector. These reviews serve as valuable feedback, influencing both the assessment of product quality and the establishment of consumer trust. In the context of Burger Bangor in Gianyar Regency, this study aims to examine the mediating role of trust in the relationship between online customer reviews and purchasing decisions. Using a purposive sampling technique, an online survey was distributed to 100 respondents who had previously purchased Burger Bangor products. The data collected were analyzed using path analysis to test the proposed hypotheses. The findings reveal that online customer reviews significantly influence purchasing decisions by positively enhancing consumer trust. Furthermore, trust itself was found to have a strong positive effect on purchasing decisions and partially mediates the relationship between online reviews and purchasing decisions. These results highlight the importance of effectively managing online customer reviews as they not only provide crucial information to potential buyers but also play a pivotal role in building trust, which in turn influences consumer purchasing behavior. For Burger Bangor, actively responding to and leveraging these reviews can be an essential strategy for improving customer trust and increasing purchase intentions, ultimately contributing to sustained competitiveness in the food and beverage industry.
