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.

The results of the study indicate that the Samsarah contract is a solution to dropship transactions. The original law is permissible or permissible if carried out in accordance with Islamic provisions.

Share trading in limited liability companies that does not comply with the procedures for transferring share ownership under the Company Law may lead to legal disputes, particularly unpaid share transactions. This study examines the annulment of share sales by the court to protect the seller’s interests when the buyer defaults, based on Article 1320 of the Indonesian Civil Code. The case analyzed is District Court Decision No. 6 K/Pdt.G/2017. Legal protection for sellers includes clauses concerning legal subjects and objects, price, payment methods, share transfer, and dispute resolution in accordance with Articles 1457 and 1513 of the Civil Code. Using a normative juridical method with statutory, conceptual, analytical, and case approaches, the study concludes that default in share sale agreements may nullify ownership rights. Therefore, strict sanctions and legal remedies through the court are essential to safeguard shareholders’ rights.

The criminal justice system in Indonesia is very concerned about money laundering crimes that continue to grow along with technological advances and the complexity of modern economic crimes. This study examines in depth the legal provisions related to TPPU in Indonesia, which is based on Law Number 8 of 2010 concerning the Prevention and Eradication of Money Laundering Crimes. This research aims to identify the role of prosecutors as law enforcers in applying elements of anti-trafficking at the investigation and prosecution stages, as well as to analyze various obstacles that arise in the evidentiary process in court. Using a normative juridical approach, this study utilizes literature analysis, court decision review, and evaluation of relevant legal provisions. The findings of the study show that proving preliminary crimes and the flow of funds from crimes requires public prosecutors to have a comprehensive understanding of money laundering mechanisms, including the placement, layering, and integration stages. In practice, prosecutors face various challenges, such as difficulties in tracing the origins of assets disguised through complex transactions, limited access to financial technology data, and lack of cooperation support between law enforcement and financial institutions. These obstacles often cause the proving process to be protracted and less effective. Therefore, it is necessary to increase the capacity of law enforcement officials, strengthen coordination between agencies, and use more optimal technology to support efforts to eradicate trafficking more effectively and comprehensively.

Business is an economic activity carried out by individuals or organizations to produce and sell goods or services with the aim of making a profit. The NSH Group Store is a business that sells carpets, pillows, bolsters, and dolls located in the Sei Dadap I/II Plantation, Sei Dadap District, Asahan Regency, North Sumatra 21225. The NSH Group Store was established in 2016 and is owned by Mrs. Siti Komariah Siregar. Among the challenges faced by the NSH Group Store owner are irregular stock procurement. Sales transaction processes still use conventional methods, reducing efficiency and time effectiveness, and potentially leading to data errors. Supply Chain Management is a series of approaches used to efficiently integrate suppliers so that goods can be distributed in the right quantities, locations, and at the right time, with the aim of minimizing overall system costs. A bolster pillow is a pillow that can function as both a pillow and a bolster. Bolster pillows are oval and long, so they can be hugged while sleeping. The benefits of a bolster pillow include maintaining a proper sleeping position, reducing pressure on joints, helping reduce aches, improving sleep quality, and improving overall health. Therefore, by implementing Supply Chain Management (SCM), data processing will be faster and more accurate.

A market is a place where buying and selling transactions take place between sellers and buyers at a specific time and place. This definition encompasses several key elements: the presence of sellers, buyers, a specific place and time, and a transaction agreement. Such markets are also known as traditional markets. "Surprise" or "overflow" markets are markets that open suddenly and briefly. "Surprise" or "overflow" markets are increasingly common in various locations. There are many reasons why people enjoy shopping at these markets. One example is the very low prices, especially compared to shopping at supermarkets or malls. Over time, with the increasing demand for basic necessities, the "surprise" market, located along the road in the Vila Mutiara Cikarang housing complex, has also experienced gradual development. The number of traders and buyers has increased, the trading space has expanded, and transaction times have decreased. This "surprise" market is located along the road in the Vila Mutiara Cikarang housing complex, starting from the second block to the end of the road exiting the housing complex. The "surprise" market operates during peak hours, especially in the morning, when this time is not only for market activities but also for many activities such as going to work, school, and other activities.

The rapid growth of digital financial technology has introduced new economic instruments that require re-evaluation through the lens of Islamic economic law, one of which is Bitcoin. This study aims to analyze the legal standing of Bitcoin as a means of transaction and investment using a normative legal approach. Data were obtained through extensive literature review involving primary and secondary sources, including Islamic jurisprudence, maqāṣid al-sharī‘ah, qawā‘id fiqhiyyah, official fatwas, and contemporary technological and economic studies. The analysis employed normative and reconstructive methods to assess the compatibility of Bitcoin’s characteristics with the principles of Islamic law. The findings indicate that Bitcoin may be classified as a form of digital māl because it possesses utility, can be lawfully owned, and is tradable within open market mechanisms. However, its extreme price volatility, limited public acceptance, and absence of state-backed legitimacy make it unsuitable as a lawful medium of exchange in Islamic transactions. Conversely, Bitcoin may be permitted as an investment instrument under strict conditions, provided the activity avoids speculative motives, ensures transparency, and follows prudent financial conduct. Based on these assessments, this study concludes that Bitcoin is more appropriately categorized as a digital commodity rather than a transactional currency. This research contributes conceptually to the development of sharia-compliant crypto-asset regulations and opens avenues for further exploration on designing more stable and ethically aligned digital financial instruments.

The results show that relationship marketing has a positive and significant effect on customer loyalty, where effective communication, responsive services, and loyalty programs such as Tokopedia Points increase customer trust and emotional attachment. In addition, e-servicescape also has a positive and significant effect on customer loyalty through an attractive interface, easy navigation, and reliable transaction security. Simultaneously, both variables make a substantial contribution to building customer loyalty toward Tokopedia. Thus, effective relationship marketing strategies and high-quality digital environments are crucial factors in maintaining customer loyalty and enhancing Tokopedia’s competitiveness in the increasingly intense e-commerce industry.

Selecting the right supplier is a critical aspect of supply chain management, especially in a retail business like Parfume Corner, which relies on product quality, availability, and on-time delivery. This study aims to implement the VIKOR (VlseKriterijumska Optimizacija I Kompromisno Resenje) method as a multi-criteria decision-making approach to determine the best perfume supplier. The VIKOR method was chosen because of its ability to handle conflicts between criteria and produce optimal compromise solutions. The evaluation criteria used include product quality, price, on-time delivery, after-sales service, and flexibility in negotiations. Data were collected from five potential suppliers through observation, interviews, and historical transaction documents. The analysis results showed that one supplier obtained the lowest VIKOR index score, thus being determined as the best compromise solution. The implementation of the VIKOR method proved effective in providing objective and transparent recommendations, which can support Parfume Corner's strategic decisions in building long-term partnerships with reliable suppliers. This approach can also be adapted by similar businesses to improve procurement efficiency and quality. The test results obtained were that in the expert test a Good value was obtained, namely 80%, while in the system test a Very Good conclusion was obtained, namely 100%.

This research examines the application of the Elliptic Curve Digital Signature Algorithm (ECDSA) in a blockchain system as a security solution for digital payment systems in Indonesia. Using a descriptive-qualitative approach based on literature review and conceptual simulations using Python, this study discusses the working principles of ECDSA, its advantages over other digital signature algorithms, and the challenges of its adoption in Indonesia. The results show that ECDSA provides high cryptographic efficiency, maintains transaction authenticity and integrity, and supports a transparent decentralized system. The academic simulations include not only KYC processes, top-ups, transactions, validation by validators, and block recording, but also demonstrates the formation of an interconnected multi-level blockchain and tests scenarios for rejecting manipulated or invalid transactions. The contribution of this research lies not only in the theoretical review but also in the implementation illustrations that can be used as a basis for education and the initial development of blockchain-based digital payment systems. The research results show that ECDSA is capable of providing a high level of efficiency in the encryption and transaction verification process, maintaining data integrity and authenticity, and supporting a decentralized and transparent system. The academic simulations included the KYC process, wallet creation using ECDSA keys, balance top-ups through bank integration, transaction creation and validation, and block recording in the blockchain. Specifically, the simulations successfully demonstrated how new blocks are added to the chain by referencing the previous block's hash, as well as how transactions with corrupted signatures, manipulated amounts, or insufficient balances are automatically rejected by the validator consensus mechanism, maintaining system integrity. This research contributes not only theoretically, but also through conceptual representations that can be used as an educational foundation and for the initial development of blockchain-based digital payment systems in Indonesia.

Credit card fraud is a critical issue in digital financial transactions. This study aims to develop and evaluate fraud detection models using Logistic Regression and Gradient Boosting on an imbalanced dataset, where fraudulent transactions constitute only a small portion of the data. To address this imbalance, the Synthetic Minority Over-sampling Technique (SMOTE) was applied during preprocessing. Logistic Regression, used as a baseline model, achieved 95% accuracy, 78.6% precision, 55.9% recall, and a 65.3% F1-score. After applying class weighting and SMOTE, recall improved to 88.7%, but precision dropped to 52%, indicating that the model became overly sensitive and prone to false positives. Gradient Boosting initially produced better results, with 98% accuracy, 95.5% precision, 84.3% recall, and an 89.5% F1-score. After hyperparameter tuning and resampling, its performance improved further to 96.7% precision, 86.1% recall, and a 91.1% F1-score. These results indicate that Gradient Boosting is more effective in handling imbalanced data and offers greater reliability in detecting fraudulent transactions. The findings support the growing evidence in favor of ensemble learning techniques in fraud detection applications. This research contributes practical insights into improving the accuracy and security of machine learning-based fraud detection systems in financial services.

Advances in information technology increasingly require communities to adapt to digital communication tools, particularly email, which functions as a key digital identity for account registration, information exchange, and online transactions. Despite its importance, digital literacy remains limited among the general public, especially rural housewives, many of whom lack awareness of the need for email accounts, have limited operational skills, and are vulnerable to cyber risks such as phishing and data theft. To address this issue, a workshop entitled “Fundamentals of Using Gmail and Account Security” was conducted for the PKK women’s group in Jompo Kulon Village to improve basic digital skills and promote safe online practices. The program aimed to introduce the functions and benefits of email, assist participants in independently creating Gmail accounts, provide knowledge on securing accounts through two-factor authentication, and train participants to send and receive emails. The workshop was delivered through an interactive face-to-face approach combining short presentations and hands-on practice using participants’ mobile devices. Initial sessions explained email as a digital identity, followed by guided account creation and security setup. The final session focused on practicing email communication to reinforce understanding. The results showed high participant engagement, with most participants successfully creating Gmail accounts, understanding essential digital security concepts, and demonstrating basic email usage skills. Overall, the activity increased awareness of personal data protection and is expected to serve as an initial step in strengthening digital literacy among women, enabling them to better adapt to ongoing technological developments.

Background: The rapid development of blockchain technology and smart contracts has fundamentally transformed contractual relationships by shifting the role of human interpretation and enforcement toward automated, code-based, and decentralized systems. This transformation generates complex legal implications, particularly regarding the evolution of contractual liability, which is increasingly distributed and no longer centered on a single legal subject. Objective: This study aims to analyze the evolution of contractual liability in smart agreements and examine how such transformation affects the fundamental principles of traditional contract law within modern legal systems. Methods: This research employs a normative and conceptual legal approach, supported by an analysis of blockchain regulations across multiple jurisdictions, case studies of smart contract implementation, and a comparative legal analysis between civil law and common law systems, complemented by a multidisciplinary literature review. Results: The findings indicate that contractual liability in smart agreements has evolved from a centralized fault-based liability model to an algorithmic, distributed, and code-dependent liability structure within blockchain ecosystems. This evolution creates new legal challenges concerning the attribution of liability, legal certainty, and the limitation of judicial intervention in automated contractual arrangements. Furthermore, the study identifies a tension between technological efficiency and substantive legal justice, highlighting the need for adaptive legal frameworks capable of accommodating decentralized technologies while ensuring the protection of legal rights and accountability of involved parties.

The development of digital technology has driven significant changes in people's transaction patterns, including the increased use of app-based financial services.

The method used was a literature review, analyzing journals, reports, and official documents related to the use of digital wallets and the development of DANA services over the past three years. The results show that DANA contributes to accelerating transaction processes, increasing accessibility to financial services, and providing secure and efficient payment features. Features such as QRIS, flexible balance top-ups, instant transfers, and integration with various public and commercial services have proven to facilitate users' cashless transactions. However, challenges remain, including unequal digital literacy, data security risks, and network limitations in some regions. Overall, the DANA app plays a crucial role in accelerating the digital payment ecosystem and increasing transaction convenience for the Indonesian people.

This study aims to analyze the issue of online gambling in Indonesia and examine the urgency of extradition agreements as a legal instrument to prosecute online gambling operators who conduct their activities from abroad. Although gambling has been declared a criminal act under the Indonesian Criminal Code (KUHP) and the Electronic Information and Transactions Law (ITE Law), its enforcement has not been effective due to the transnational nature of this crime, in which gambling operators run their platforms from other countries, placing them beyond the direct reach of Indonesian jurisdiction. The research employs a normative legal methodology, examining statutory regulations, principles of criminal law, and relevant legal literature. The objects of study include the 1945 Constitution, the Criminal Code, and the ITE Law as the legal foundations for combating online gambling, as well as provisions concerning extradition within the framework of international cooperation. The findings indicate that although Indonesia normatively possesses legal grounds to prosecute perpetrators abroad through the principles of personality and protection, implementation remains hindered by state sovereignty and jurisdictional limits. Government efforts to block gambling websites have proven ineffective, as new sites continually emerge. Therefore, extradition agreements are essential and urgent as a solution to overcome jurisdictional barriers, enabling the transfer of offenders to Indonesia for prosecution and ensuring state protection for citizens from the harmful impacts of online gambling.
