The rapid development of digital technology has significantly transformed financial transactions in Indonesia, particularly through the growing use of e-wallets as practical and efficient payment tools. In a country with a Muslim-majority population, ensuring that e-wallet services comply with Islamic principles—free from riba, gharar, and maysir—is essential. This study aims to analyze Indonesia’s legal politics in regulating the use of e-wallets within the Islamic financial system and to assess their alignment with sharia principles. This research employs a normative juridical method with a qualitative descriptive approach by examining laws, regulations, and fatwas related to sharia-based fintech. The findings indicate that the Indonesian regulatory framework—through the OJK, Bank Indonesia, and DSN-MUI—has attempted to harmonize policies to support sharia-compliant digital financial services. However, several challenges remain, including limited e-wallet platforms with sharia certification, low digital sharia literacy among users, and the absence of detailed technical regulations specific to sharia e-wallet operations. This study recommends strengthening regulatory guidelines, increasing public literacy, and enhancing collaboration between regulators and the fintech industry to promote the development of sharia-compliant e-wallets that are secure, innovative, and aligned with Islamic financial principles.

The development of the digital world has brought significant changes to various aspects of people's lives, including the family economy. Digitalization opens up new opportunities for economic activity, particularly through the use of social media, marketplace platforms, and digital financial services. However, many people still lack adequate digital literacy and are therefore unable to optimally utilize this technology to increase family income. This community service activity aims to improve the community's digital literacy and encourage the use of digital technology as a means of sustainably increasing family income. The implementation method includes providing training on the basics of digital literacy, digital-based entrepreneurial mentoring, and hands-on practice in using social media as a promotional tool, marketplaces as sales channels, and digital financial services to support business transactions. The results of the activity indicate an increase in public understanding of the use of digital technology, a change in a more adaptive entrepreneurial mindset, and the emergence of various digital-based business initiatives. The use of digital technology has been proven to open new economic opportunities and make a positive contribution to increasing family income.

The rapid development of digital technology, especially after the COVID-19 pandemic, has brought changes to people's behavior and lifestyle with the trend of digital payments. One of the advances in digital financial services technology is PayLater, a Fintech innovation that offers easy transactions in the form of loans and installments without a credit card. This study aims to analyze the influence of transaction convenience and risk perception on purchasing decisions using the PayLater feature on e-commerce platforms among Generation Z in Samarinda City. This study uses a quantitative approach with associative methods and multiple linear regression analysis using SPSS 27. The method used is purposive sampling to obtain a sample of 100 respondents from Generation Z in Samarinda City, aged 18-28 years, who have used PayLater on e-commerce platforms. The findings show that transaction convenience (X1) has a positive and significant effect on purchasing decisions, but risk perception (X2) does not have a significant effect on purchasing decisions. At the same time, both variables have a significant effect on purchasing decisions. The findings of this study are expected to provide valuable insights for the PayLater feature to design more effective strategies to improve customer satisfaction and transaction experience.

This study analyzes the effectiveness of using BNI Bank’s QRIS in improving transaction convenience and efficiency at the canteen of Universitas 17 Agustus 1945 (UNTAG) Surabaya. The research was conducted by a team led by Ida Ayu Nuh Kartini, S.E., M.M., together with students of the Management Study Program, during November–December 2025. The rapid development of digital banking has encouraged the adoption of QRIS as a standardized non-cash payment system regulated by Bank Indonesia. This study aims to examine the level of QRIS BNI utilization, assess ease of use (application access and QR code scanning), and evaluate transaction efficiency, including time savings, queue reduction, and error minimization. A descriptive quantitative approach was employed using a survey method with a five-point Likert scale questionnaire distributed to 36 respondents consisting of students, lecturers, and administrative staff who had used QRIS at the canteen. Primary data were analyzed descriptively using averages and percentages, supported by relevant literature. The results show that QRIS is perceived as highly effective, with scores above 90% for ease of use (95%), transaction speed (92.78%), reduction of change-related issues (97.78%), support for digitalization (97.22%), and security (91.11%). The main limitation identified is dependence on internet connectivity (85%). Overall, respondents strongly support the full implementation of non-cash payment systems at the campus canteen.

The development of information technology has given rise to a new form of business transaction: the electronic contract. This contract form replaces the traditional process that requires a physical meeting between the parties. However, questions arise regarding the validity of e-contracts from the perspective of Indonesian civil law, specifically based on Article 1320 of the Indonesian Civil Code (KUHPerdata) and the provisions of Law Number 11 of 2008 concerning Electronic Information and Transactions (UU ITE). This research aims to analyze the validity of electronic contracts as legally binding agreements and to assess the extent to which the ITE Law can serve as their legal basis. Using a normative juridical legal research method, the research results show that e-contracts are valid and binding as long as they meet the requirements for the validity of an agreement under Article 1320 of the Civil Code, namely consent, capacity, a specific object, and a lawful cause. The ITE Law expands the recognition of electronic evidence and digital signatures as valid evidence in civil law. Thus, electronic contracts have the same legal force as conventional contracts, as long as they meet the principles of free will and the integrity of a reliable electronic system.

The rapid development of e-commerce as part of the broader digital transformation has introduced various new forms of transactions that were not explicitly recognized in classical Islamic jurisprudence. These include digital contracts, non-physical goods, cloud-based services, and electronic payment systems. Such innovations present a range of legal challenges, particularly concerning the validity of contracts, the legal status of digital products, the permissibility and security of electronic payment methods, and the protection of consumers in online transactions. To address these challenges, Islamic scholars have increasingly turned to ijtihad the process of independent reasoning and interpretation—as a methodology capable of providing legal solutions for contemporary issues. This study employs a qualitative approach, primarily through literature review, to examine the foundational principles of ijtihad, various methodological tools, and their applicability to different aspects of e-commerce transactions. The findings demonstrate that ijtihad methods, including qiyās (analogical reasoning), istislāh (consideration of public interest), istihsān (juridical preference), and ‘urf (customary practice), enable Islamic law to remain adaptive and flexible, while still oriented toward justice and public welfare. By applying these methods, Islamic jurisprudence can provide legal certainty, uphold fairness, and ensure that e-commerce practices align with Shariah principles, ultimately fostering trust and ethical behavior in the digital marketplace.

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.

The development of information technology has transformed trade from traditional markets to digital platforms, including Cash on Delivery (COD) payment systems. This study analyzes the integration of the COD system with the istishna contract in online transactions (specifically on Shopee), its implementation mechanisms, and its validity according to Islamic jurisprudence (fiqh muamalah). The research method used a descriptive qualitative approach through digital observation and literature review. The focus of the study was on pre-order or custom product transactions made after a specification agreement between the buyer (mustashni') and seller (shani'). The results showed that the COD system is valid in the istishna contract because it allows for final payment upon receipt of the goods. This is in accordance with Sharia law as long as the product specifications are clear, the price is transparent, and the buyer's right to khiyar is fulfilled to ensure the goods conform to the contract. As long as it is free from riba (usury), gharar (gharar), and tadlis (tadlis), the COD method in istishna transactions reflects fairness, openness, and benefits for both parties in the digital economy ecosystem.

The development of digital technology has driven significant changes in people's transaction patterns, including the increased use of app-based financial services. This study aims to analyze the role of the DANA app in increasing the convenience of cashless transactions in Indonesia. 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.

Background: The rapid development of financial technology and the increasing volume of cross-border transactions have led to the emergence of increasingly complex digital financial crimes, involving anonymous actors and exploiting regulatory gaps and jurisdictional differences. This condition poses serious challenges to legal systems, particularly in terms of digital evidence, the attribution of legal liability, and the effectiveness of cross-border law enforcement. Objective: This study aims to reconstruct the framework of civil and criminal liability in digital fraud cases to make it more adaptive, integrated, and responsive to technological developments. Method: The research employs a qualitative socio-legal approach, combining normative analysis of cybercrime regulations, case studies of international digital fraud, comparative analysis of legal systems across countries, and interviews with legal practitioners and fintech regulators. Results: The findings reveal significant legal gaps, regulatory fragmentation across jurisdictions, and weaknesses in electronic evidence systems that hinder effective law enforcement. Additionally, the complexity of actors and technologies within digital ecosystems complicates the accurate attribution of legal responsibility. Therefore, an integrated legal framework is required, incorporating both civil and criminal liability, international regulatory harmonization, and the utilization of technology to enhance law enforcement effectiveness.

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.

Private vehicles are a frequently used mode of transportation because they are considered more practical. However, using private vehicles carries several risks, such as traffic accidents due to drivers losing focus on the road due to other activities, such as making calls on smartphones, drinking, or operating the radio. Approximately 90% of accidents are caused by human error. Convolutional Neural Network (CNN) is a type of neural network commonly used on image data. CNN is often used for image classification due to its high performance and accuracy. Therefore, this study aims to analyze the performance of CNN for the classification of distracted driving activities. The results show that the CNN model is able to effectively classify images of distracted driving activities, with an accuracy of approximately 99% across all datasets and across all input image size variations. Furthermore, the results of this study also show that differences in right-hand and left-hand drive datasets do not significantly affect model accuracy. Variations in input image size also do not significantly affect model accuracy, but do affect the training duration.

Public service reform in Indonesia increasingly emphasizes inter-agency collaboration as a mechanism to enhance administrative efficiency, service integration, and responsiveness to citizens’ needs; however, in many regions, including West Kotawaringin Regency, collaborative practices remain fragmented due to uneven human resource (HR) capacities, inconsistencies in standard operating procedures (SOPs), and limited technological integration across institutions. This study aims to examine the current state of HR collaboration, identify key barriers and enabling factors, and propose an integrated and adaptive HR collaboration model to strengthen public service delivery. Using a qualitative multi-case study approach, data were collected through semi-structured interviews with leaders and operational staff from multiple regional government agencies and analyzed using NVivo 15 to generate thematic coding and visual tools such as word clouds, hierarchy charts, and project maps. The findings indicate that current collaboration is largely transactional and administrative, exemplified by the physical co-location of agencies at the Public Service Mall (MPP) without effective systemic interoperability. Three critical themes emerged: gaps in HR distribution, competencies, and role clarity; structural and behavioral constraints including sectoral ego, SOP discrepancies, and limited digital integration; and opportunities to enhance collaboration through shared digital dashboards, inter-agency forums, and cross-functional HR mobility. Based on these results, the study proposes a three-pillar Integrated and Adaptive HR Collaboration Model comprising comprehensive digital integration, flexible HR competency sharing, and inclusive service co-creation involving community stakeholders, offering both theoretical contributions to collaborative governance and practical guidance for regional governments seeking to improve public service effectiveness.

The development of information technology has encouraged various organizations, including cooperatives, to digitize their service systems. The Credit Cooperative (Kopdit) CU Mera Ndi Ate is one of the cooperatives that still uses a manual system in managing savings and loans, which causes the service process to be slow, inaccurate, and has a high risk of recording errors. This study aims to design and build a web-based savings and loans system that can be used by members of Kopdit CU Mera Ndi Ate. This system allows members to conduct transactions online, view transaction history, and monitor savings or loan balances. The research methods used are observation, interviews, and literature studies. The system development process uses a waterfall model with stages of analysis, design, implementation, and testing. The result of this study is a prototype of a web-based savings and loans information system that has main features such as member registration, transaction recording, financial data management, and automatic financial report generation. With the implementation of this system, it is hoped that the cooperative can improve work efficiency, speed up services, and provide easy access to information to all members.

The Community Service Program (Kuliah Kerja Nyata / KKN) of Universitas Muhammadiyah Tangerang (UMT) in Sukadiri Village, Tangerang Regency, was implemented with the aim of empowering the community through strengthening tourism-based MSMEs and raising environmental awareness. This program employed a participatory qualitative descriptive approach, in which students acted as facilitators in assisting the community. The main focus included sustainable tourism literacy, MSME digitalization, waste segregation management, and community literacy improvement. Key activities carried out consisted of designing logos and digital branding for MSMEs, conducting ecoprinting training utilizing local flora, delivering legal counseling on bullying within the scope of the Electronic Information and Transactions Law (ITE), creating educational boards and segregated waste bins, establishing a reading corner, and supporting food security through corn planting. The results indicated increased community awareness of environmental management, improved skills of MSME actors in utilizing digital technology, and the growth of literacy culture among children and youth. In addition to providing tangible benefits for the community, this program also enriched students’ experiences in applying their academic knowledge directly in the field. Therefore, the KKN in Sukadiri Village not only contributed to sustainable village development but also served as a best practice model that could be replicated in other regions.

As the business and technological environment evolves, modern accounting is no longer limited to recording historical transactions, but has developed into a strategic information system that emphasizes transparency, accountability, and the use of technology and integrated reporting to create long-term value. From a theoretical perspective, the development of accounting is closely related to agency theory, which explains the relationship between principals and agents. Unlike agency theory, stewardship theory assumes that management is motivated by the interests of the organization and principals rather than the personal goals of managers. The conceptual differences between agency theory and stewardship theory also influence modern accounting practices. This study was conducted to analyze the conceptual differences between agency theory and stewardship theory, the factors that distinguish the two theories, and the relevance of both theories in accounting practice. This research was conducted using a descriptive qualitative approach or comparative literature study. Empirical research results show that both theories have their own relevance according to the context of the company, so neither is completely superior. Agency theory and stewardship theory also offer different but complementary perspectives in explaining the relationship between owners and managers in modern accounting practices.  

Over the past 20 years, developments in digital technology have led to the emergence of financial innovation in the form of cryptocurrencies, with Bitcoin being the main pioneer. Bitcoin is a decentralized, blockchain-based electronic payment system that is not controlled by a single financial institution. Although its presence facilitates quick and straightforward cross-border transactions, it also raises ethical and legal issues, especially when taking into account Islamic law, which strongly emphasizes justice, certainty, and the welfare of society. This paper aims to investigate the usage of Bitcoin in modern economic transactions from the standpoint of Islamic and international law. This study investigates Islamic legal sources, the views of Islamic scholars, fatwas (religious decrees), and international laws and regulations pertaining to cryptocurrency assets using a qualitative, normative-empirical methodology. The results show that, although opinions among scholars differ, the usage of Bitcoin is subject to ijtihadiyah (Islamic ijtihad) in Islamic law. Some reject it because of its great volatility and speculative potential, while others allow it as long as it provides advantages and does not include riba, gharar, or maysir (the risks associated with gambling). In terms of international law, Bitcoin is typically seen as a digital asset that has to be closely watched in order to preserve economic stability and deter financial crime. Therefore, balanced legislation is required to guarantee that the usage of Bitcoin is in line with the principles of sharia maqasid and global economic fairness.

Automatic motorcycle spare part sales have increased along with the high use of automatic two-wheeled vehicles in the community. To support optimal sales strategies and stock management, customer purchasing pattern analysis is required. This study uses the FP-Growth algorithm to identify association patterns between automatic motorcycle spare part products that are frequently purchased together. FP-Growth was chosen because of its ability to efficiently find frequent itemsets without the need to generate candidate itemsets as in the Apriori algorithm. Transaction data is processed to form an FP-Tree which is then extracted to find relationships between items. The analysis results show combinations of products that frequently appear together, such as brake pads and engine oil, which can be used as a basis for compiling sales packages, product placement, and product recommendations. By implementing the FP-Growth algorithm, spare part stores or workshops can improve service and efficiency in sales management.

In social life, buying and selling are fundamental mechanisms for transferring rights, beginning with an agreement. According to Articles 1313 and 1338 of the Indonesian Civil Code, agreements are legally binding acts with the force of law for the parties involved. One high-value transaction is the sale and purchase of apartment units, which involves developers as sellers. In practice, developers often fail to deliver units within the agreed timeframe. This study examines (1) the developer’s responsibility toward buyers when units are not delivered and (2) the legal protection available for buyers under such circumstances. The research applies Hans Kelsen’s Theory of Responsibility and Satjipto Rahardjo’s Theory of Legal Protection, using a normative juridical method based on library research. Primary, secondary, and tertiary legal materials were analyzed through statutory, conceptual, analytical, and case approaches, employing grammatical and systematic interpretation, legal analogy, and legal refinement. Findings reveal that developers are primarily responsible for delivering fully paid units. Failure to fulfill this obligation, due to breach of contract or negligence, triggers legal liability in the form of performance or compensation. Legal protection for buyers ensures their rights are safeguarded, and even in cases of developer negligence or bankruptcy, consumers are legally entitled to receive the apartment units they have purchased.
