Consumers are divided into three categories: initial consumers, middle consumers, and end consumers. These three types of consumers certainly have the right to protection, but end consumers as users need to receive more attention to protection, especially in the buying and selling process. This study uses a sociolegal approach with a purposive sampling method to examine the selling process. In addition, this study also examines how protection for end consumers is implemented in LPG buying and selling activities in Balikpapan Tengah District. Thus, this study aims to contribute to the understanding of protection efforts and the impact of not implementing protection properly in Balikpapan Tengah District, a densely populated area. This study is expected to be a reference for the development of consumer protection efforts in the buying and selling of subsidized LPG, as well as providing insight into the consequences that can be received by end consumers and their handling in the future.

The advancement of information technology has rapidly transformed trading patterns in Indonesia, shifting from conventional transactions to online transactions through marketplace platforms. On one hand, this transformation provides convenience and efficiency for both businesses and consumers. On the other hand, it has also given rise to various legal issues, particularly regarding consumer protection. This article aims to examine how legal protection for consumers is implemented in electronic sales agreements on marketplaces, while also identifying the obstacles encountered during its implementation. The study employs a normative juridical approach, using conceptual analysis and legislative review, supplemented by empirical data obtained from interviews. As described, legal protection for consumers in electronic transactions in Indonesia remains suboptimal. Specifically, these challenges include biased law enforcement, low levels of consumer literacy, and ineffective dispute resolution mechanisms. In practice, marketplaces have incorporated consumer protection features such as escrow systems, refund mechanisms, and complaint centers; however, their implementation still suffers from limited transparency and effectiveness. Furthermore, existing regulations are slow to respond to the dynamics of cross-border transactions and ongoing digital innovations. Therefore, comprehensive regulatory reform, stronger enforcement, and enhanced legal and digital literacy among the public are necessary to ensure effective consumer protection.

Purworejo Regency is one of the centers of herbal plant production in Indonesia. One of these is lemongrass, which is widely found in the Ngombol area. Furthermore, this plant can be used to make herbal products. However, the selling value of this plant is still relatively low because it relies solely on middlemen or collectors. One product made from lemongrass is essential oil. The goal of this Community Service program is to increase the selling value of lemongrass and provide new business opportunities to increase the income of local farmers, especially Mrs. Kasminah in Wonosari Village, Ngombol District, Purworejo Regency. The implementation method includes preparation, core, and completion. The result of this activity is the creation of a new innovation in the form of a practical herbal drink without preservatives that has quite good market potential and is in demand by consumers. Then, the product is branded Sempontea. Achievements during the activity include a significant increase in income, as well as the creation of effective offline and online marketing strategies. This activity also succeeded in establishing a sustainable business ecosystem and increasing environmental awareness through the use of herbal plants.  Overall, this community service activity has succeeded in increasing the selling value of lemongrass plants, improving the economy of local farmers, and providing social and economic impacts for the community through the utilization of local resources.

The development of automotive technology continuously seeks solutions to improve human mobility and address environmental concerns. This study focuses on the Hydrogen Reactor (HHO) technology as an alternative solution for fuel efficiency and emission reduction, specifically examining the legal protection of consumers utilizing this technology at Bengkel Karya Gemilang. The research aims to analyze the legal framework of consumer protection in the context of new energy-saving technologies and to identify the legal responsibilities of business actors (workshops) and the rights of consumers. Employing a normative legal research method with a case study approach, the study analyzes the implementation of Law No. 8 of 1999 concerning Consumer Protection (UUPK) in the utilization of HHO reactors. The findings indicate that while the HHO reactor technology offers a potential 5-15% increase in fuel efficiency and CO emission reduction, its implementation introduces new legal challenges, particularly regarding product safety, standardization, and the obligation for periodic servicing. Consumer protection is primarily ensured through the workshop’s obligation to provide clear product explanations, guarantee product safety, and fulfill the periodic service commitment. The study concludes that the existing UUPK provides a sufficient legal basis, but its implementation requires clear and transparent agreements, especially concerning the technical specifications and long-term maintenance of the HHO reactor, to ensure consumer rights are fully protected against potential risks associated with new, non-standardized automotive technologies.

The convenience offered by digital trading systems provides various benefits for both consumers and business actors, such as time efficiency, ease of access, and broader market reach. However, behind these advantages, there are also several risks that may harm consumers, including discrepancies between product descriptions and actual goods, delivery delays, and potential online fraud. This study aims to analyze the legal protection for consumers in electronic transactions and the responsibilities of business actors within digital commerce systems. This research employs a normative legal research method using statutory and conceptual approaches. The findings indicate that consumer legal protection in electronic transactions has been regulated in various laws and regulations; however, in practice, several challenges remain in its implementation. Therefore, strengthening regulations, enhancing supervision of business actors, and increasing public legal awareness are necessary to create a safer electronic transaction system and ensure legal certainty for consumers.

This study is motivated by the rapid advancement of digital marketing and the increasing influence of psychological factors in shaping consumer behaviour, particularly among Generation Z, who are highly exposed to social media and global trends in imported skincare products. This phenomenon suggests that purchase decisions are not solely driven by digital marketing strategies but are also significantly influenced by emotional drivers such as Fear of Missing Out (FoMO). Accordingly, this study aims to analyse the effects of affiliate marketing, WhatsApp status, celebrity advertising, and FoMO on the purchase intention of Generation Z consumers in Tangerang City. Specifically, the study pursues five objectives: (1) to examine the effect of affiliate marketing on purchase intention; (2) to analyse the influence of WhatsApp status on purchase intention; (3) to investigate the impact of celebrity advertising on purchase intention; (4) to evaluate the effect of FoMO on purchase intention; and (5) to assess the simultaneous effects of all independent variables on purchase intention. This study adopts a quantitative approach using a survey method, with data collected through structured questionnaires administered to 250 respondents selected via accidental sampling. Data were analysed using multiple linear regression with the aid of SPSS software to examine the relationships among variables. The findings reveal that all independent variables exert a positive and statistically significant influence on purchase intention, with FoMO emerging as the most dominant predictor. These results underscore the greater role of psychological factors relative to digital marketing strategies in driving purchase intention among Generation Z consumers.The contribution of this study lies in integrating digital marketing strategies and psychological factors into a single empirical model, while also highlighting the growing importance of interpersonal digital communication, such as WhatsApp, in contemporary marketing contexts. From a practical perspective, the findings provide managerial implications for businesses to design marketing strategies that are not only informative but also capable of creating urgency and fostering emotional engagement among consumers.

The obligation to consume halal food is a fundamental right of Muslim consumers, guaranteed by Islamic principles and Indonesian positive law. However, in practice, many food business operators still distribute products that have not obtained halal certification, resulting in legal uncertainty and potential material and immaterial losses for Muslim consumers. This study aims to analyze the forms of legal protection available to Muslim consumers regarding food products that are not halal-certified and to examine the responsibility of business actors as well as the role of the government in ensuring halal food compliance in Indonesia, using Sushi Go Restaurant as a case study. This research applies a normative juridical method with a statutory and case approach, supported by library research of primary, secondary, and tertiary legal materials. The findings indicate that legal protection for Muslim consumers has been comprehensively regulated through Law Number 8 of 1999 on Consumer Protection and Law Number 33 of 2014 on Halal Product Assurance. Nevertheless, the implementation of these regulations remains inadequate, particularly in terms of supervision and law enforcement against non-compliant business actors. The absence of halal certification and insufficient disclosure of halal information at Sushi Go Restaurant potentially violates Muslim consumers’ rights to legal certainty and accurate information. Therefore, stronger regulatory enforcement, improved supervision, and increased awareness among business actors and consumers are essential to ensure effective legal protection for Muslim consumers.

Digital transformation has transformed the tourism promotion landscape through social media, travel marketplaces, and user-experience-based content. Visual, interactive, and rapidly disseminating digital information shapes destination images and influences traveler decisions. However, the lack of digital promotion standards allows for misleading promotional practices, visual manipulation, false testimonials, and exaggerated claims that have the potential to harm tourism consumers. This study aims to analyze the synchronization between the Electronic Information and Transactions Law (UU ITE) and the Tourism Law in overseeing digital tourism promotion. This study uses a normative juridical method with a legislative approach and a literature review of academic documents and related news. The research findings show that while both laws share the same goal of ensuring accurate and non-misleading information, neither provides specific technical standards for digital promotion. The ITE Law is general and does not specifically regulate tourism promotion, while the Tourism Law was drafted before social media became a primary tool for destination marketing. This has resulted in regulatory gaps and fragmented authority between the Ministry of Communication and Informatics, the Ministry of Tourism and Creative Economy, BPKN, and BPSK. This research recommends the establishment of derivative regulations related to digital promotion, ethical content standards, advertising transparency, and an integrated cross-agency oversight mechanism to protect tourism consumers in the digital space.

The game industry in Indonesia has shown significant growth in recent years, along with the increasing public interest in high-quality video games. AAA (triple-A) games such as Grand Theft Auto VI (GTA VI) rely heavily on trailers as their primary promotional tool to introduce the game’s atmosphere, visual quality, and complex storytelling. GTA is widely recognized as a pioneer in realistic visuals, deep narratives, and social criticism delivered through iconic storytelling, making it highly appealing to potential consumers. This study aims to examine the influence of visual narrative in the GTA VI trailer on consumers’ purchase intention within the Indonesian GTA V Roleplay Facebook community. The theoretical framework is based on Marketing Communication Theory, Visual Narrative Theory with the dimensions of clarity, realism, dynamism, and continuity, as well as Purchase Intention Theory consisting of transactional, referential, preferential, and exploratory intentions. A quantitative approach was employed using a survey method, with questionnaires as the data collection instrument. The sample was selected using simple random sampling and calculated using the Slovin formula with a 5% margin of error, resulting in 92 respondents. The results indicate that the visual narrative variable achieved the highest mean score in the realism dimension (3.29), while purchase intention recorded the highest mean score in the transactional intention dimension (3.79). Simple linear regression analysis reveals that visual narrative has a significant influence on purchase intention, with a correlation coefficient (R) of 0.918. The coefficient of determination (R²) of 0.843 indicates that 84.3% of purchase intention is influenced by visual narrative, while the remaining 15.7% is affected by other factors beyond this study.

Distribution transformers play a critical role in delivering electrical energy from medium-voltage networks to low-voltage consumers. At ULP Medan Kota, several distribution transformers have been operating with loads exceeding 80% of their nominal capacity, posing risks of overloading, efficiency reduction, and equipment failure. This study aims to analyze the performance of distribution transformers based on actual load data and evaluate mitigation strategies through the implementation of additional parallel transformers (trafo sisip). The methodology includes data collection, load and current calculation, and simulation of load distribution after transformer insertion. The results show that the installation of trafo sisip reduces the load on the main transformer by approximately 50% and significantly lowers the current to safer levels. Moreover, placing the trafo sisip at an optimal position minimizes voltage drop to as low as 0.0745 Volts. Therefore, the addition of trafo sisip is proven to enhance the reliability, efficiency, and operational life of the power distribution system at ULP Medan Kota.
