Abstract:This study aims to analyze and formulate a concept of Islamic legal protection for crypto investors in responding to the dynamics of digital crimes within virtual currency transactions. Departing from the rapid development…
nt of blockchain technology and the recognition of crypto assets as tradable commodities in Indonesia, this research identifies a normative ambiguity between positive law and religious fatwas, particularly concerning the permissibility and legal legitimacy of cryptocurrencies from a sharia perspective. The inherent characteristics of crypto assets-namely volatility, speculative tendencies, and vulnerability to digital crimes such as hacking, fraud, market manipulation, and money laundering-generate significant risks for Muslim investors. Within the framework of fiqh al-muʿāmalāt and maqāṣid al-sharīʿah, especially the principle of ḥifẓ al-māl (protection of wealth), this study asserts that investor protection constitutes not merely a regulatory necessity but an integral dimension of the higher objectives of Islamic law in safeguarding justice, transparency, and economic welfare. Methodologically, this research employs a normative-maqāṣidī approach through an interdisciplinary analysis integrating Islamic jurisprudence, national positive law, and the study of digital financial technology. The focus of the inquiry is directed toward identifying the typologies of digital crimes within the crypto ecosystem, evaluating the effectiveness of national regulations and religious fatwas, and formulating a model of Islamic legal protection that is preventive, corrective, and educational in nature. The expected outcome of this dissertation is the construction of a conceptual framework of ḥimāyah al-mustatsmir (investor protection) grounded in maqāṣid al-sharīʿah, adaptive to the digital era, and strengthened through synergy among the state, financial authorities, and fatwa institutions. Accordingly, this study contributes not only to the advancement of contemporary fiqh al-muʿāmalāt discourse but also offers an applicable normative framework for the development of a secure, equitable, and sustainable sharia-based digital economic system.
Abstract:This research is motivated by the issue of the effectiveness of witness and victim protection within the Indonesian criminal justice system, which is considered not yet to fully reflect the values of restorative justice…
nor to be harmoniously integrated into the framework of the national legal system. Although regulatory frameworks have been established through Law Number 13 of 2006 as amended by Law Number 31 of 2014 concerning the Protection of Witnesses and Victims, as well as various regulations related to whistleblower and justice collaborator protection, their implementation continues to face normative and structural weaknesses. The lack of synchronization between the Criminal Procedure Code (KUHAP), the Draft Criminal Procedure Code (RUU KUHAP), and other sectoral regulations has resulted in the suboptimal role of the Witness and Victim Protection Agency (LPSK) in guaranteeing the rights of witnesses, victims, perpetrator-witnesses, and reporters, particularly in criminal cases with broad and organized impacts. From the perspective of maqāṣid al-syarī‘ah and the Pancasila Justice Theory, legal protection for witnesses and victims should not be merely procedural-formal in nature, but must be directed toward the restoration of dignity, the assurance of security, and the comprehensive protection of human rights. This study aims to analyze the regulatory weaknesses in witness and victim protection from the perspective of the criminal justice system and to reconstruct such regulations based on restorative justice values. Employing a normative legal research paradigm combined with conceptual, statutory, and theoretical approaches, this research positions the Pancasila Justice Theory as the grand theory, the Legal System Theory as the middle theory, and the Legal Protection Theory as the applied theory. The findings indicate that regulatory reconstruction is necessary through strengthening the institutional position of LPSK, harmonizing it with the Draft Criminal Procedure Code (RUU KUHAP), and reinforcing the protection of whistleblowers and justice collaborators in a more comprehensive and non-discriminatory manner. This reconstruction is directed toward establishing a witness and victim protection system oriented toward restoration (restorative justice), balanced interests among the parties, and the realization of social justice as mandated by the values of Pancasila and human rights principles.

ck of teacher motivation, minimal professional training, and suboptimal communication between leaders and staff are factors that hinder performance improvement. Therefore, adaptive and innovative leadership strategies are needed to create a conducive work environment and encourage improvements in the quality of education. Methodology: This research uses a descriptive qualitative approach with data collection methods through participant observation, in-depth interviews, and documentation studies at MTsN 1, MTsN 2, and MTsN Preparatory State Islamic Junior High School 3. Padangsidimpuan. Data were analyzed using the Miles and Huberman model through data reduction, data presentation, and conclusion drawing. The results of this study showed that the madrasah principal implemented eight main strategies in building effective leadership to improve teacher performance; (1). Coaching strategy, through training, individual mentoring, and Professional Learning Community (PLC). (2). Supervision strategy, based on participatory academic supervision and constructive feedback. (3). Motivation strategy, through verbal appreciation, emotional support, and professional development. (4). Reward strategy in the form of certificates, incentives, and additional task trust. (5). Discipline strengthening strategy with a systemic, restorative approach, and based on a collective work culture. (6). Family gathering strategy to build emotional bonds and social capital in the madrasah environment. (7). Structured academic supervision strategy through a cycle Collaborative planning, observation, and reflection. (8) Lesson Study strategy as a vehicle for developing distributive leadership and improving the quality of learning. Effective leadership of madrasah principals is built through a holistic approach that integrates administrative, pedagogical, and relational aspects. The implemented strategy has proven significant in improving teacher performance through increased competence, motivation, collaboration, and a positive work culture. This study recommends the need to strengthen teacher development programs and leadership training based on Islamic values for the sustainable improvement of educational quality in madrasahs.
Abstract:This paper presents the design and performance evaluation of a high-voltage direct current (DC) generator based on the Cockcroft–Walton (CW) voltage multiplier for laboratory-scale applications in electrical engineering.…
g. Conventional high-voltage generation methods often involve bulky transformers and complex circuitry, making them less suitable for compact and cost-effective laboratory use. To address these limitations, a modular CW-based system is proposed, integrating a high-frequency input source with an optimized diode-capacitor ladder network. The proposed system is designed to achieve high DC voltage output in the kilovolt range while maintaining acceptable levels of ripple and efficiency. Experimental results show that the system can achieve up to 86% of the theoretical output voltage under no-load conditions, with an efficiency of around 70.8%. Furthermore, the ripple voltage of the generated output voltage is very small, demonstrating stable performance suitable for laboratory applications. The proposed design offers a compact, cost-effective, and reliable solution for high-voltage DC generation, making it highly suitable for educational and low-power applications.
Abstract:Infrastructure management in outermost border islands is not only a matter of physical development, but also a strategic issue related to sovereignty, community welfare, connectivity and national defence. This article examines…
amines infrastructure management on Miangas Island, one of Indonesia’s northernmost outer islands bordering the Philippines. Although Miangas already has several basic and strategic infrastructures, including roads, an airport, a port, electricity facilities, clean water sources, telecommunications, health facilities and security infrastructure, these assets have not yet functioned as an integrated and reliable system. The main problem is therefore not the absence of infrastructure, but the gap between physical availability and functional performance. This study uses a qualitative descriptive-analytical approach based on field observation, semi-structured interviews and document review. Data were analysed using the Miles and Huberman model, supported by STEEP+M and SWOT analysis. The findings show that infrastructure management in Miangas is influenced by three main indicators: infrastructure availability and quality, connectivity and accessibility, and infrastructure sustainability. Internally, Miangas has strengths in its strategic geography, existing infrastructure assets, state institutional presence, social cohesion and strong national identity. However, these strengths are constrained by weak service quality, limited maintenance, unstable connectivity, a fragile local economy and inadequate maritime surveillance. Externally, Miangas benefits from national legal support, strategic policy status and Indonesia–Philippines cooperation, but faces threats from cross-border dependence, illegal fishing, border violations, environmental pressure and geopolitical sensitivity. The SWOT analysis places Miangas in the WO quadrant, meaning that external opportunities should first be used to overcome internal weaknesses. This article proposes the Civil-Military Corridor Resilience Model as an integrated framework that connects public services, logistics, energy, local markets, maritime security and territorial defence in one border resilience system.
Abstract:The growing emphasis on sustainable urban mobility has positioned electric vehicles (EVs) as a strategic component of transport transformation, particularly in developing cities with constrained infrastructure systems. One…
ne of the key challenges in supporting EV adoption is the provision of accessible charging infrastructure, which is closely related to user perception of acceptable service distance. This study aims to determine the optimal service distance of Electric Vehicle Charging Stations (EVCS) based on user preferences in Pekanbaru City, Indonesia, and to explore its implications for spatial planning. A quantitative approach was employed using a questionnaire survey of 51 respondents distributed across 15 administrative districts. All respondents were non-EV users, representing potential adopters in the early stage of transition. The survey captured preferred EVCS distance using interval-based categories, along with respondents’ awareness and intention toward EV adoption. The results indicate that the dominant preferred distance falls within the 2–4 km range, with an estimated mean of 3.08 km and a standard deviation of 1.98 km, resulting in an effective range of approximately 1–5 km. Considering urban road network constraints and detour factors, this range is further adjusted to 3–6 km to reflect more realistic travel conditions. These findings suggest that a relatively dense and accessible charging network is required to reduce range anxiety and support EV adoption. From a spatial planning perspective, a 4 km service threshold is proposed as a practical reference for EVCS deployment, representing the central tendency of user preferences within the adjusted range. This study highlights the importance of integrating user-based spatial parameters into infrastructure planning and contributes to the literature by emphasizing the role of perceived accessibility in shaping EV infrastructure demand in developing urban contexts.
Abstract:This study aims to analyze consumer segmentation in the traditional culinary business of a Madurese duck rice and fried chicken restaurant in Konawe Regency. This study used a descriptive qualitative method with data collection…
lection techniques including interviews, observation, and documentation. Informants consisted of the owner, employees, and customers who had visited the restaurant two or more times. The analysis was conducted based on four types of market segmentation: geographic, demographic, psychographic, and behavioral. The results of this study indicate that this restaurant has a fairly broad market segment, encompassing both local and out-of-town customers, with consumers predominantly students, office workers, and families. Authentic taste, affordable prices, and fast service are the main factors attracting customers. Geographic segmentation indicates potential for expansion due to the increase in out-of-town visitors on weekends. Demographic and psychographic segmentation indicate that customers have a high interest in traditional, spicy dishes. Behavioral segmentation indicates the presence of loyal customers and repeat purchasing patterns. These findings provide important recommendations for businesses to develop more effective marketing strategies tailored to the characteristics of their target market.

chitecture, rice field views, and regional cuisine as key attractions for its customers. This study used a qualitative approach, using direct interviews and field observations. The results indicate that customer satisfaction is determined by several key factors: quality products made from fresh ingredients, friendly and responsive service, and a strategic location that creates an emotionally comfortable atmosphere. The research findings indicate that these three factors work synergistically, creating a dining experience that is not only functionally satisfying but also strengthens the emotional and cultural aspects of customers. Thus, Galu Resto is able to provide added value through an approach that combines local culture and a natural setting. This research is expected to provide a reference for the development of local culinary businesses with a model based on experience and cultural values.
