This study examines the implementation of the Coretax system in preparing electronic withholding tax slips (e-Bupot) and submitting Monthly Income Tax Article 21 (PPh 21) Returns at PT RSA. Coretax, launched by the Directorate General of Taxes (DGT) and officially implemented on January 1, 2025, is part of the government’s effort to modernize tax administration and improve taxpayer compliance. The research uses a qualitative descriptive method with a case study approach. Data were obtained through interviews with personnel responsible for PPh 21 administration, direct observation of e-Bupot preparation and monthly tax return filing through Coretax, and documentation review of tax reports and withholding slips. The analysis compares PT RSA’s practices with applicable tax regulations and identifies technical challenges during system use. The results show that PT RSA has complied with prevailing regulations, including the application of the Average Effective Rate (TER) and the utilization of Coretax for tax administration. However, technical constraints remain, particularly unstable internet connections and slow Coretax server performance during peak reporting periods, leading to data entry delays and upload failures. Therefore, improvements in system stability and performance are needed to support timely reporting and optimal tax compliance.

This research explores how monopoly markets operate in the context of a sharia-based microeconomy, with a primary focus on how prices are regulated based on the principle of adl or justice. Unlike traditional monopolies, which often create inefficiencies in resource allocation and exploit consumers, Islamic teachings require fair prices, in accordance with the Quran's prohibition of gharar (uncertainty) and zulm (oppression). Referring to the theories of Ibn Taymiyyah and modern thinkers such as Chapra, we examine how monopoly companies can achieve maslahah or mutual benefit through profit restrictions, combining prices with zakat, and supervision by a sharia council. Through a simple mathematical model, we prove that monopolies regulated by justice produce better Pareto outcomes than equilibria that only maximize profits, by reducing social losses while still encouraging innovation. Empirical data from Islamic markets in Indonesia, such as halal commodities, support these findings, where regulations can stabilize prices at 15-20% lower. The conclusion of this study highlights the importance of Sharia principles in managing sustainable markets in developing countries, with policy recommendations to reform antitrust rules to align with the maqasid al-Shariah.

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.

Modern society faces multidimensional complexities, ranging from spiritual crises and technological disruption to social inequality. Muslims, with their theological and intellectual capital, are often perceived as suboptimal in responding to these challenges contextually and applicatively. This article aims to analyze the fundamental problems faced by Muslims in formulating answers to the problems of modern society and to explore the strategic role of Islamic higher education institutions, specifically the Muhammadiyah University of Malaysia (UMAM), in bridging this gap. This research uses a qualitative approach with a case study method at UMAM. Data was collected through literature study, observation, and structured interviews with academics and policymakers at UMAM. The findings indicate that the main problems lie in: (1) the dichotomy between naqli and aqli sciences, (2) a static approach to religious texts, and (3) a lack of integrative and innovative solution models. UMAM strives to address these issues through three main strategies: integration of knowledge in the curriculum, problem-based research, and empowering community engagement. This article concludes that UMAM has the potential to become a model social laboratory of Islam that combines the Muhammadiyah renewal ethos with the Malaysian socio-cultural context to produce relevant, humanist, and rahmatan lil 'alamin solutions.

The authority of the Religious Courts in Indonesia has undergone substantial transformation since the enactment of the 1974 Marriage Law, which serves as a foundational milestone in harmonizing the national legal system on family matters. Prior to this legislation, the jurisdiction of the Religious Courts was limited and influenced by legal dualism among customary law, Islamic law, and Western civil law inherited from the colonial period. This article examines how the Marriage Law initiated a shift in the structure and legitimacy of the Religious Courts and how their jurisdictional expansion reached a more comprehensive form through Law No. 7 of 1989 on Religious Courts and its subsequent amendments under Law No. 3 of 2006 and Law No. 50 of 2009. Using a normative juridical approach, this study analyzes statutory regulations, academic literature, and Islamic legal doctrines. The findings show that the Marriage Law provided the initial legal foundation for strengthening the Religious Courts' authority in handling family disputes, which was later expanded significantly to include inheritance, wills, grants, endowments (wakaf), alms (zakat), charitable donations (infaq and sadaqah), and Islamic economic matters during the legal reform era. This transformation not only reinforced the institutional structure of the Religious Courts but also improved access to justice for Muslim communities and supported the integration of Islamic law into Indonesia’s national legal framework. Therefore, the development of the Religious Courts’ authority after the Marriage Law reflects the dynamic modernization of the legal system and the harmonization between religious values and the rule of law in Indonesia.

The development of lanthanum-doped barium hexaferrite materials has attracted considerable attention in the field of functional materials, particularly as electromagnetic wave absorbers. This literature review aims to analyze advances in synthesis methods, structural characteristics, magnetic properties, and electromagnetic absorption performance of lanthanum-doped barium hexaferrite reported in various studies.

Lanthanum doping is known to modify lattice parameters, reduce coercivity, and enhance complex permittivity and permeability, which play crucial roles in absorption mechanisms. Furthermore, variations in dopant concentration significantly influence reflection loss values and effective absorption bandwidth. The reviewed literature indicates that optimization of composition and synthesis routes can produce materials with high absorption capability, good stability, and strong potential for application in electromagnetic interference mitigation devices. This review is expected to serve as a conceptual reference for future development of lanthanum-doped barium hexaferrite–based electromagnetic wave absorbing materials. The comparative approach also highlights research challenges, industrial application opportunities, and future research directions relevant to the evolving demands of modern communication and defense technologies at both national and global levels.

This research extends the previous work of Tsaqila, Winiarti, and Widaningrum (2024), who applied the Complex Proportional Assessment (COPRAS) method within a decision support system for supermarket branch location selection. Unlike the prior study, which focused on Ponorogo through a web-based framework, this study expands the implementation of COPRAS to the Medan Area, Medan Kota, Medan Polonia, dan Medan Maimun districts, adapting it to local urban, social, and economic characteristics. The main objective is to identify the most strategic site for a new supermarket by analyzing multiple criteria, including land cost, population density, accessibility, safety, cleanliness, and disaster risk. Data were collected from both field surveys and official government publications. The findings reveal that the COPRAS method provides reliable and objective assessments among the evaluated alternatives, with Medan Area emerging as the most suitable location for supermarket development. Overall, this study broadens the practical scope of the COPRAS method in a different regional context and reinforces its reliability and adaptability as a multi-criteria decision-making tool in the modern retail industry.

This study examines the optimization of military defense in North Sulawesi as a supporting pillar for Indonesia’s new import gateway. Positioned strategically on the Pacific rim, North Sulawesi is expected to become a hub for imported goods to support national economic equalization. However, this import route shift also brings security challenges, including military and non-military threats such as smuggling, maritime crimes, and potential infiltration by terrorist groups. This research employs a qualitative descriptive method based on literature study, focusing on the analysis of naval and air defense strategies, modernization of main weapon systems (alutsista), and the enhancement of human resources within the Indonesian National Armed Forces (TNI). The results indicate that strengthening defense infrastructure, including the addition of warships, patrol vessels, and modern fighter aircraft, is urgently needed to maintain regional stability. Furthermore, the application of the smart defense concept, integrating advanced technology with local community empowerment, can sustainably enhance maritime resilience. Investment in the defense sector has been shown to create a conducive climate for international trade, boost investor confidence, and strengthen Indonesia’s economic connectivity with the Asia-Pacific region. This study recommends synergy between the Ministry of Defense, TNI, and the national defense industry to accelerate the modernization and maintenance of alutsista, while ensuring the security of trade routes in North Sulawesi. With these measures, North Sulawesi can function optimally as a strategic import gateway that supports national economic growth and reinforces state defense.

This study discusses the comparison of traditional and modern management accounting methods with the aim of analyzing the characteristics, advantages, and disadvantages of each method and providing practical guidance for corporate decision-making. The research method uses a literature review approach, collecting and synthesizing various recent studies related to Activity Based Costing (ABC), Target Costing, and Balanced Scorecard (BSC), and comparing them with traditional methods such as job order costing and process costing. The analysis results show that traditional methods are simpler and easier to implement, but less accurate in calculating costs and less relevant for strategic decision-making. In contrast, modern methods offer higher accuracy through detailed cost allocation, comprehensive performance monitoring, and data-based decision-making support, although they require greater implementation complexity and resources. This study concludes that the choice of method must be adjusted to the characteristics of the company and the complexity of business activities, so as to optimally improve cost efficiency and profitability.

This study discusses the relevance and role of hybrid learning strategies as a conceptual solution to the crisis of effectiveness in traditional fiqh learning in Islamic boarding schools in the digital age. The background of this study stems from the problem of declining efficiency and interactivity of classical learning methods such as sorogan and bandongan amid technological developments that demand pedagogical innovation. This study aims to analyze theoretically how the integration of traditional pesantren values and modern learning approaches can be applied without eliminating spiritual identity and scientific sanad. The method used is library research with a descriptive-analytical approach through a review of the latest scientific literature on Islamic education and hybrid learning. The results show that a hybrid learning model based on synchronous and asynchronous approaches can increase flexibility, effectiveness, and student participation in the learning process, while maintaining personal relationships with teachers. The theoretical implications enrich the concept of integrating Islamic education and technology, while the practical implications offer an adaptive curriculum model for Islamic boarding schools to respond to the challenges of the digital age without abandoning Islamic values.

The development of the Industrial Revolution 4.0 to the Society 5.0 era presents new challenges for education, including Islamic Religious Education (PAI). PAI is required not only to transfer religious knowledge but also to shape character, morality, and 21st-century competencies. This study aims to examine the philosophical foundations, characteristics, and application of PAI learning models to ensure their relevance in modern education. The research employed a qualitative approach with a library research design, involving the exploration of primary and secondary literature, critical reading, systematic note-taking, and content analysis validated through triangulation of classical and contemporary sources. The findings indicate that PAI learning models are conceptual, theoretical, systematic, and rooted in religious, philosophical, psychological, and sociological foundations. Four main models behavioristic, information processing, social, and humanistic each have strengths and limitations, yet their integration is relevant to forming insan kamil, a holistic human being balanced in cognitive, affective, psychomotor, spiritual, and social aspects. Therefore, developing PAI learning models based on Islamic philosophy and adaptive to technological advancements is a strategic necessity to face global challenges.

This study aims to systematically analyze the influence of Work Family Conflict (WFC) and Work Life Balance (WLB) on employee performance through a Systematic Literature Review (SLR) approach. The increasing demands of work and family roles in modern organizational settings make these variables highly relevant in organizational behavior research. The SLR procedure was conducted based on guidelines by Kitchenham and Wahono, consisting of planning, conducting, and reporting stages. Literature searches were performed across several academic databases, including Google Scholar, Garuda Ristek, ResearchGate, and university journal portals, covering publications from 2020 to 2025. From a total of 5,992 identified articles, 28 studies met all inclusion and quality criteria and were reviewed in depth. The findings indicate that Work Family Conflict consistently exerts a negative effect on employee performance by increasing stress, reducing concentration, and impairing psychological well-being. Conversely, Work Life Balance demonstrates a significant positive influence on performance, as employees who successfully balance their professional and personal responsibilities tend to exhibit higher productivity, job satisfaction, and engagement. Furthermore, factors such as organizational support, flexible working arrangements, and job satisfaction are shown to mediate or moderate the relationship between WFC, WLB, and employee performance. This study contributes by mapping the latest empirical patterns and providing recommendations for organizations to develop supportive work policies that enhance employee well-being and sustainable performance.

The cigarette industry in Dawe District, Kudus, has been the backbone of the local economy for decades. However, this heavy dependence on a single industrial sector creates economic vulnerability, especially when production fluctuations or policy changes affect the tobacco industry.

Spirituality is a fundamental foundation of congregational faith life that directly influences character formation and daily behavior. However, social, cultural, and technological changes in the modern era have contributed to the weakening of congregational spirituality, including within the GKSI Sungai Maram congregation in Ketapang Regency, West Kalimantan. This condition is reflected in faith practices that tend to be routine and have not yet fostered holistic Christlike character. This community service program aimed to revitalize congregational spirituality as an effort to strengthen character formation and faith through a contextual and participatory approach. The program was implemented through pastoral mentoring, reflective group discussions, prayer fellowships, and community-based faith development activities involving church leaders and congregants. The implementation methods included initial observation of congregational conditions, interviews with church leaders and members, and community reflection as an evaluation tool. The results of the program indicate increased spiritual awareness among congregants, reflected in the strengthening of Christian character values such as love, integrity, responsibility, and social concern, as well as improved relational quality within the congregation. In addition, the program encouraged the establishment of sustainable shared spiritual practices as an integral part of church life. Therefore, contextual and sustainable spiritual revitalization through community service activities serves as an effective strategy for building a congregation that is mature in faith, strong in character, and socially impactful.

 The development of modern education requires a strong philosophical foundation to ensure that learning processes are not merely technical but oriented toward holistic human formation. This article aims to comprehensively analyze the role of the philosophy of science within contemporary education through a conceptual exploration grounded in an extensive literature review. The philosophy of science with its three major pillars: ontology, epistemology, and axiology serves as an analytical framework for understanding the nature of human beings, the structure of knowledge, and the values embedded within educational objectives. The research methodology employs the Miles and Huberman data analysis model, consisting of data reduction, data display, and conclusion drawing/verification. The findings indicate that the philosophy of science plays a strategic role in providing direction and orientation for the development of humanistic, adaptive, and globally responsive education. Moreover, this study reveals that the advancement of scientific knowledge encounters significant challenges, including ontological complexity, epistemological crises driven by digital disruption, moral degradation, and shifting scientific paradigms.
