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 existence of banking institutions has an important role in the country's economy. Banking institutions have three main functions, namely financial intermediary, agent of development and agent of trust. The existence…
and sustainability of banking institutions must be pursued as much as possible by bank managers, because their existence can improve the economy. One of the efforts made by banking institutions is to channel credit to parties in need to meet customer needs and obtain benefits for banking institutions. The research method includes explanatory-descriptive-quantitative research. The population is 24,675 consumer credit customers of BRIGuna Bank BRI in the horseshoe area, East Java. The sample is 250 customers who have received BRIGuna consumptive credit at least twice in a row, using non-probability sampling-purposive sampling on a quota basis. Analysis tools and techniques using SPSS, SEM, and AMOS version 24. Data collection techniques using a questionnaire / google form and interviews. Service quality and innovation of a bank will improve the company's image, sustainable competitive advantage based on loyalty and the intention to re-elect in one bank. Innovation also affects customer satisfaction, while loyalty-based sustainable competitive advantage is also influenced by the image of banking companies. Loyalty-based sustainable competitive advantage affects the intention to re-elect in a bank. Further research to be more specific on the quality of consumer credit services, requires a collaborative approach to customers which is social capital and focuses on innovation that provides convenience for customers while maintaining the company's image in the eyes of customers because this is the key to a loyalty-based sustainable competitive advantage.
Abstract:This study examines the effectiveness of in absentia judgments in the recovery of assets from corruption crimes based on Article 38 of the Law on the Eradication of Corruption Crimes. The background of this study is based…
d on the phenomenon of many corruption defendants who are absent from trial, so that the judicial process continues through the in absentia mechanism. However, the effectiveness of such judgments in supporting the recovery of state financial losses remains a problem, especially in the aspects of execution and the return of assets resulting from corruption crimes. This study uses a normative legal method (normative juridical) with a statutory approach and a conceptual approach. The results of the study indicate that normatively, Article 38 of the Anti-Corruption Law provides a valid legal basis for courts to render judgments without the presence of the defendant. However, the effectiveness of such judgments in asset recovery is still not optimal because there are obstacles such as difficulties in tracing assets, transfer of asset ownership, limited coordination among law enforcement institutions, and weak asset tracing mechanisms. In addition, there are also juridical obstacles in the form of the lack of comprehensive technical regulations regarding the execution of assets in in absentia cases. Therefore, strengthening regulations and increasing synergy among law enforcement officers are required so that the objective of recovering state losses can be achieved effectively.
Abstract:This study aims to analyze the urgency and mechanisms of implementing Restorative Justice in resolving family conflicts from the perspective of Islamic Family Law. Amid the high rates of divorce and domestic violence, formal…
rmal litigation approaches often fail to repair fractured relationships among family members. This research employed a qualitative method with a normative juridical approach. Data were collected through literature studies of Islamic legal texts, Indonesian statutory regulations, and related literature on Restorative Justice. The findings indicate that the concept of Restorative Justice has strong relevance to the principle of Ishlah (reconciliation) in Islamic Family Law. Unlike the retributive approach, which focuses on punishment, Restorative Justice prioritizes relationship recovery, forgiveness, and collective welfare. In practice, instruments such as mediation in Religious Courts and the role of Hakam (peace mediators) represent clear manifestations of these restorative values. The study concludes that integrating Restorative Justice into the family law system is not only effective in reducing divorce rates but also capable of preserving the psychological well-being of family members, especially children. The academic contribution of this study lies in providing a theoretical foundation for the development of positive law in Indonesia to become more accommodative toward non-litigation dispute resolution based on religious values and local wisdom. The researcher recommends strengthening technical mediation regulations so that they do not merely become procedural formalities in court.
Abstract:This study aims to examine the effect of service quality and customer intimacy on donor loyalty, with donor satisfaction as a mediating variable, at LAZNAS BMH Surabaya. The research adopts a quantitative approach using…
Partial Least Square Structural Equation Modeling (PLS-SEM) and involves 376 active donors as respondents. The results indicate that service quality and customer intimacy have significant positive effects on donor satisfaction and donor loyalty. Customer intimacy shows a stronger direct influence on donor loyalty compared to service quality. Furthermore, donor satisfaction significantly affects donor loyalty and serves as a partial mediating variable in the relationship between service quality and customer intimacy with donor loyalty. The findings highlight that donor loyalty in Islamic philanthropic institutions is not only driven by service performance but also by relational engagement and satisfaction. Therefore, integrating service excellence with relationship-based strategies is essential to enhance donor loyalty and ensure long-term sustainability. This study contributes to the literature by providing empirical evidence on donor behavior within the context of Islamic philanthropy and offers practical insights for improving donor relationship management.
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.

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.
Abstract:This study aims to understand the level of customer satisfaction with the product quality, service, and location at Galu Resto. Located in Wawotobi, Southeast Sulawesi, Galu Resto combines a natural concept with local architecture,…
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.

t 15 respondents based on specific criteria. The perception indicators used are internal factors, including physiological aspects, interest, attention, unidirectional needs, and emotional conditions. Data analysis was conducted using a Likert scale to measure the fishermen's perception levels toward the program. The research results indicate that fishermen generally have a positive perception of the Advanced Fishermen Village Program across all the indicators used. The cumulative value of the internal factor reached 35.73, which falls into the high category. This indicates that the program was well-received and considered beneficial by the fishermen at the research location. The Maju Fisherman Village Program has strong potential in supporting the improvement of fishermen's welfare. However, sustainable support and effective implementation strategies are needed to maintain and enhance the program's impact.
