This research aims to evaluate the effectiveness of Online Travel Agent (OTA) distribution channels in influencing room sales volume and net profit for hotels in Java. Although OTAs have become a primary distribution choice that successfully boosts sales figures, there is still a lack of research highlighting the impact on net profitability due to high commission costs.Using a quantitative associative method through panel data regression analysis, this study examines the causal relationship between the proportion of sales made via OTAs and two performance indicators over a two-year period (2021–2023). The primary findings reveal a dual effect:OTA Distribution Channels have a positive and significant influence on Room Sales Volume (supporting Hypothesis H1).Conversely, OTAs have a significant negative impact on Hotel Profit Margins (supporting Hypothesis H2), indicating a substantial financial trade-off.The contribution of this research is to provide balanced empirical evidence regarding volume gains versus margin losses resulting from OTA usage. The managerial implications suggested by these findings are that hotels need to implement distribution strategies focused on Net Revenue Management and channel mix optimization to achieve a balance between volume requirements and profitability.

The purpose of this scientific study is to examine the influence of review content and customer ratings on the trust of Uniwara Economics Education students in skincare products. The background of this study includes the increasing popularity of local skincare products and the shift in the behavior of young consumers who now rely more on reviews and ratings on various social media platforms such as Instagram and TikTok when deciding to buy. Students, as a critical and digitally native generation, use online information as their main source for building trust in products. This study applies a quantitative method with an associative research design. The sample consists of 51 students from a total population of 105 students, determined through Proportional Stratified Random Sampling. Data for the study were collected using questionnaires and analyzed using multiple linear regression techniques. The results of this study indicate that review content and customer ratings together have a positive and significant effect on student trust. In part, these two variables also significantly affect trust. The contribution of review content and customer ratings is 247% (as indicated by an Adjusted R Square value of 0.247), while the rest is influenced by other variables or factors outside the scope of this study. This research indicates that review content and customer ratings have both a partial and simultaneous effect on the trust of Uniwara Economics students in skincare products.

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.

This study aims to analyze the effect of information technology (IT)-based learning media on improving students' academic performance. With the advancement of digital technology, the use of IT-based media such as interactive presentations, educational videos, Learning Management Systems (LMS), and online quiz applications has become part of modern teaching strategies. This study uses a quantitative approach with a quasi-experimental method. The subjects of the study were secondary school students divided into experimental and control groups. The instruments used include learning achievement tests to measure academic performance and observation sheets to assess the implementation of IT media usage. Data were analyzed using t-tests and simple regression analysis. The results show a significant difference in academic performance between students who used IT-based learning media and those who used conventional methods. The experimental group showed a higher average score compared to the control group. These findings indicate that the use of IT-based learning media, when planned and implemented systematically, can improve students' motivation, engagement, and understanding of learning materials. Therefore, the integration of information technology into the learning process is recommended as an innovative strategy to enhance the quality of education.

The development of digital technology and the widespread use of social media, particularly Instagram and TikTok, have opened opportunities for online interaction but also increased the risk of cyberbullying. Cyberbullying is aggressive behavior via digital media intended to harm or degrade others. One psychological factor believed to influence this behavior is emotional regulation, which is the ability to manage and express emotions appropriately in different situations. This study aims to examine the relationship between emotional regulation and cyberbullying behavior among early adult students in Jambi. A quantitative approach with a correlational design was used, involving 127 students aged 18–25 years, selected through purposive sampling. Data were collected using an online questionnaire, which included an emotional regulation scale and a cyberbullying behavior scale. Data analysis was conducted using the Pearson Product Moment correlation test with SPSS software. The results showed a significant negative relationship between emotional regulation and cyberbullying behavior, with a correlation coefficient of r = -0.632 and a significance level of p < 0.001. This indicates that students with better emotional regulation skills are less likely to engage in cyberbullying. Thus, enhancing emotional regulation skills could be an effective strategy in preventing cyberbullying among students.

The development of Digital Marketing and Electronic Word of Mouth (eWOM) has encouraged hospitals to adopt digital communication strategies to attract patients’ visit intentions. However, in public hospitals, the effectiveness of these strategies in influencing patient behavior still requires empirical validation. This study aims to analyze the influence of Digital Marketing and eWOM on patient visit intention, with Brand Awareness as an intervening variable at RSUD Cengkareng.This research employed a quantitative approach with an explanatory design. Data were collected from November to December 2025 from 100 general outpatient respondents selected using the Slovin formula and a simple random sampling technique. The data were gathered through structured questionnaires and analyzed using Structural Equation Modeling (SEM) with AMOS software.The results show that Digital Marketing and eWOM have a positive and significant effect on Brand Awareness. Both variables also significantly influence patient visit intention, with eWOM demonstrating the strongest effect. These findings indicate that information shared through digital platforms and patient recommendations plays an important role in shaping potential patients’ decisions to visit the hospital. However, Brand Awareness does not have a significant effect on patient visit intention and does not mediate the relationship between Digital Marketing, eWOM, and visit intention. This suggests that, in the context of RSUD Cengkareng as a public hospital, patients’ visit decisions are more directly influenced by digital information exposure and the credibility of online recommendations rather than by brand recognition alone.

This study aims to analyze the impact of immersive commerce and augmented reality (AR) on consumer trust in e-commerce transactions using secondary industry data from the BrandXR 2025 Research on Augmented Reality in Retail & E-Commerce. Quantitative data was analyzed descriptively to evaluate the adoption rate of immersive technologies (immersive commerce and AR) and their relationship with consumer trust perceptions. The results show that immersive commerce, characterized by interactive and realistic user experiences, has a positive impact on consumer trust. Similarly, AR which offers realistic product visualization, has a significant impact on strengthening consumer trust in purchasing decisions. Simultaneously, the integration of immersive commerce and AR enhance the digital shopping experience, which can reduce risk perception and increase trust in online transactions. These findings empirically contribute to the literature on digital consumer behavior and e-commerce strategies, and suggest that businesses adopt immersive technologies to increase consumer trust and engagement in the online commerce ecosystem.

The increasing integration of internet technology in educational institutions requires structured network governance to ensure that digital resources support academic activities effectively. Unrestricted access to online platforms often leads to non-academic usage such as online gaming and social media engagement during instructional hours, which may reduce learning concentration and degrade network performance. This research develops and evaluates a network access control simulation using a MikroTik RouterBoard RB951Ui-2HnD device. The system applies firewall filtering mechanisms, hotspot-based authentication, and bandwidth allocation strategies through Simple Queue configuration. Network segmentation is implemented to differentiate teacher and student access privileges. The study adopts a Research and Development (R&D) approach to design, configure, test, and evaluate the proposed system. Testing results indicate that the firewall configuration successfully restricts access to selected online games (Mobile Legends, Clash of Clans, Roblox) and social media platforms (YouTube, TikTok, Shopee, Instagram, Telegram). Furthermore, bandwidth management demonstrates effective traffic prioritization, ensuring more stable allocation for teacher accounts in accordance with configured maximum limits. The findings confirm that structured firewall and bandwidth policies can improve network discipline, enhance performance stability, and support a controlled digital learning environment in schools.

In the digital era and free market, technology is growing rapidly. Consumers and businesses are now more inclined to use digital transactions rather than face-to-face cash transactions. This study aims to find solutions and receive feedback related to the implementation of the Consumer Protection Law in the Digital Era and Free Market. The method used in this activity is through counseling and discussion. From the results of this activity, it was concluded that Law No. 8 of 1999 concerning Consumer Protection needs to be updated immediately as it is no longer relevant to the current digital technology, which has advanced far and is different from the conditions in 1999 when the consumer protection law was issued. The results of this activity indicate that the Consumer Protection Law No. 8 of 1999 requires comprehensive updates to accommodate the development of digital transactions, personal data protection, and consumer rights in cyberspace. Furthermore, the importance of educating consumers about their rights in digital transactions is also a key focus, so that the public can avoid losses resulting from unsafe online transactions.

The rapid advancement of information and communication technology has positioned e-commerce as a primary shopping channel, with Shopee emerging as the most popular platform in Indonesia. In the context of online fashion purchases, consumers face inherent limitations due to the inability to physically inspect or try products. Consequently, product ratings and reviews function as critical forms of social proof, helping to reduce uncertainty and perceived purchasing risk. This study investigates the influence of product ratings and reviews on purchasing decisions for fashion products on Shopee, focusing on undergraduate students at Universitas 17 Agustus 1945 Semarang. Employing an associative quantitative approach, data were collected through a closed-ended questionnaire distributed to 100 purposively selected respondents who had purchased fashion products on Shopee within the last three months. The independent variables are product ratings and product reviews, while the dependent variable is the consumer purchasing decision. Statistical analyses include validity and reliability testing, correlation analysis, t-tests, F-tests, and the coefficient of determination. The study’s findings are expected to offer both practical insights for e-commerce businesses in developing effective digital communication strategies and theoretical contributions to the understanding of digital consumer behavior in the e-commerce environment.

The rapid development of e-commerce in Indonesia makes transactions easier for consumers, but also presents various losses, such as fraud, goods that do not match the description, leaks of personal data, and problems with returning goods. In this context, Law Number 1 of 2024 concerning the Second Amendment to Law Number 11 of 2008 concerning Information and Electronic Transactions (UU ITE) exists as a legal basis which is expected to provide protection for consumers in online buying and selling transactions. This research aims to explore and analyze the effectiveness of the legal protection provided by the ITE Law for consumers, with a focus on protection for detrimental transactions, consumer personal data, as well as dispute resolution mechanisms. The research method used is a normative approach with a literature study of statutory regulations and related legal literature. The research results show that the ITE Law provides quite comprehensive legal protection, including the obligation of electronic system operators to ensure the security of transactions and personal data, as well as regulating sanctions for perpetrators of fraud. However, even though regulations already exist, implementation and consumer understanding of their rights is still a major challenge.

Micro, Small, and Medium Enterprises (MSMEs) play a vital role in the economy and community independence. However, the great potential of home-based businesses is often hindered by administrative issues related to business legality. This research focuses on UMKM Krecek Kulit Sapi Ashif in Jatirejo Village, which has been operating since 2018 but lacks a Business Identification Number (NIB), Household Industry Food (PIRT) permit, and halal certification due to perceived complex procedures. The main objective of this activity is to strengthen business management through product standardization and obtaining legal certifications to enhance the competitiveness of this MSME. The research method used a descriptive qualitative approach with a community service method based on mentoring, including observation, in-depth interviews, and hands-on practice in managing documents through the Online Single Submission system. The results show that through phased mentoring, UMKM Krecek Kulit Sapi Ashif successfully obtained an NIB and increased the owner’s awareness of PIRT food safety standards and halal certification procedures. The impact of this activity includes meeting administrative legality and improving knowledge, confidence, and professionalism in business management. Intensive mentoring proved crucial in transforming informal businesses into formal, legally protected entities.

The rapid spread of hoaxes and disinformation in the digital era poses serious challenges to social cohesion, societal stability, and the internalization of moral values, particularly within Muslim communities. The circulation of unverified information has the potential to trigger conflict, polarization, and a decline in public trust. This study aims to explore digital literacy as an ethical and religious instrument in actualizing the Islamic principle of amar ma’ruf nahi munkar in the contemporary digital sphere. Employing a qualitative library research approach, the study examines classical Islamic sources, including the Qur’an and Hadith, alongside contemporary literature on digital communication ethics and digital citizenship. The findings indicate that digital literacy from an Islamic perspective extends beyond technical competence in accessing and disseminating information; it represents a form of moral responsibility (amanah) grounded in honesty (ash-shidq), prudence, and accountability. Practices such as information verification (tabayyun), clarification, and corrective engagement in online spaces are concrete expressions of amar ma’ruf nahi munkar. Strengthening ethically grounded digital literacy is therefore essential for fostering a healthy, just, and civilized digital public sphere.

This study focuses on an in-depth analysis of how digital marketing strategies influence the decisions of residents of Mencirim Village, East Binjai District in purchasing health products. The scope of digital marketing studied includes social media platforms, the effectiveness of online advertising, the depth of marketing content, and the role of electronic reviews or electronic word of mouth (e-WOM). Using a quantitative approach with a survey method, this study involved 100 respondents selected through a purposive sampling technique. The main criteria for respondents were residents aged at least 17 years who had actively transacted health products digitally in the last three months. Data were collected through a 5-point Likert scale questionnaire and processed using multiple linear regression analysis with the help of IBM SPSS Statistics 26. The research findings revealed that partially, social media (β = 0.312), online advertising (β = 0.287), marketing content (β = 0.241), and e-WOM (β = 0.198) had a positive and significant influence on consumer purchasing decisions (p < 0.05). Collectively, the integration of these four variables explains 68.4% (R² = 0.684) of the dynamics of local purchasing decisions.

This community service activity aims to improve students' digital legal literacy and awareness of mental health from the perspectives of criminal law, civil law, and health law at SMP Al-Ikram Medan. The background of this program is the increasing use of digital media among students which raises legal risks such as cyberbullying, online fraud, privacy violations, and their impacts on students’ mental health. The method used includes legal education, interactive counseling, group discussions, and evaluation through pre-test and post-test. The results show an increase in students’ understanding of digital legal risks, students’ rights and obligations in cyberspace, and awareness of mental health protection. This program contributes to strengthening preventive legal culture and early mental health protection among students.

The Cash on Delivery (COD) system is one of the payment methods frequently used in online buying and selling transactions, where consumers pay for ordered products upon receipt of the goods. Although it provides convenience, this system often causes problems, especially related to transaction cancellations by consumers after the delivery process has been carried out by business actors. This research examines how the regulation and allocation of risk for goods return in the COD system according to the Civil Code and the forms of legal protection provided to business actors against the risk of goods return in the COD system according to Law Number 8 of 1999 concerning Consumer Protection. The method used in this research is normative, supplemented by literature study results such as legislation. The results show that the Civil Code recognizes the concept of risk as a legal consequence related to the possibility of losses on the object of the agreement, and legal protection for business actors is divided into preventive legal protection and repressive legal protection.

Transaction logs in online retail provide opportunities for data-driven customer segmentation. This study segments customers at two scopes global (all countries) and United Kingdom (UK) using Recency, Frequency, and Monetary (RFM) features derived from the Online Retail transaction dataset. After cleaning cancellations and invalid records, RFM variables are computed per customer and normalized. K-Means clustering is applied separately for global and UK data, while the number of clusters is selected via the elbow criterion and validated using internal indices. The best configuration for both scopes yields five clusters, with moderate separation quality based on the silhouette score. Cluster profiling indicates distinct groups ranging from low-frequency low-spending customers to highly frequent high-spending customers. The comparison between global and UK segmentation shows similar structural patterns, yet different proportions across segments, supporting targeted retention and value-driven marketing actions.

Burnout is a psychological condition characterized by emotional exhaustion, depersonalization, and decreased personal achievement, commonly experienced by medical students. Mindfulness, defined as awareness and acceptance of the present moment without judgment, has been increasingly studied as a strategy to reduce burnout. This narrative literature review aims to evaluate the effectiveness of mindfulness interventions in reducing burnout levels among medical students. Articles were collected from PubMed, ScienceDirect, and Google Scholar published between 2020 and 2025. Studies indicate that mindfulness-based programs, such as Mindfulness-Based Stress Reduction (MBSR) and brief online mindfulness training, effectively reduce emotional exhaustion and improve psychological well-being. Mindfulness promotes self-regulation, decreases stress reactivity, and enhances empathy, which are essential for medical students’ mental health. In conclusion, mindfulness interventions show significant potential in alleviating burnout among medical students and should be considered as part of medical education curricula.
