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:This research examines the manifestation of syncretism in Dusun Catak, Kebonagung Village, Sumowono District, Semarang Regency, with a focus on the tradition of offering sesajen and its interaction with Islamic teachings.…
. The aims of this research are to understand how syncretism is manifested in the lives of the Dusun Catak community, to comprehend the history of Dusun Catak, and to analyze the Islamic perspective on the practice of offering sesajen carried out by the Dusun Catak community. This research uses a descriptive qualitative method, combining literature study by exploring previous research, conducting direct observations at the research location for four days, and performing in-depth interviews with several informants. The results show that syncretism in Dusun Catak is manifested in a unique form, where the tradition of sesajen adapts to Islamic teachings. The Dusun Catak community also preserves the village's historical traditions by passing them down through generations. The placement of sesajen is carried out in specific locations. The practice of offering sesajen is regarded as a form of local wisdom that is not perceived as deviating from religious norms by the community; although the offerings are placed in various locations and are associated with respect for the ancestors of the Catak community, the practice is understood as part of a cultural tradition that is integrated with the Islamic values upheld by the community.
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: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: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 develop and examine the effectiveness of religious moderation in digital media based on the Dick and Carey learning model. The research is grounded in the increasing use of digital media as a primary source…
ource of religious information, which has the potential both to strengthen and to undermine the values of religious moderation. The study employed a qualitative approach with a Research and Development (R&D) design. The subjects were university students who actively use digital media. Data collection techniques included interviews, observations, questionnaires, and documentation, while data analysis followed the Miles and Huberman model. The results indicate that students’ understanding of religious moderation remains largely normative and is not yet accompanied by adequate digital literacy skills. The development of the Dick and Carey-based learning model produced interactive digital media, including educational videos, digital modules, and social media content. Implementation of the model demonstrated a significant improvement in students’ comprehension, tolerance, and critical thinking regarding religious content in digital media. Furthermore, the study found that integrating constructivist approaches, social learning, and digital literacy into the learning design effectively reinforced the internalization of religious moderation values. The developed learning model proved effective in enhancing student engagement and fostering inclusive and tolerant attitudes.In conclusion, promoting religious moderation in digital media requires a systematic, technology-based learning approach. This study provides both theoretical and practical contributions to the development of a learning model for religious moderation in the digital era.

Abstract:• DEF is a company engaged in the sale of coffee, both wholesale and retail. Currently, the sales recording system is still carried out manually, which often leads to problems such as delays in reporting, data entry errors,…
rors, and difficulties in retrieving historical information. This study aims to improve the efficiency and accuracy of the sales recording system by implementing the INDEX MATCH and SUMIFS functions in Microsoft Excel. The research method used is descriptive qualitative with a case study approach, involving observation, interviews, and documentation of the existing system. The results show that the use of INDEX MATCH and SUMIFS can accelerate the data retrieval process, improve the accuracy of sales reports, and reduce input errors. This study provides a practical solution for small and medium enterprises (SMEs) in implementing an efficient sales recording system without requiring significant investment in ERP software. However, the system still has limitations, such as dependence on Excel files that are vulnerable to damage or unintended changes, and the lack of advanced automation features such as receivables reminders or inter-departmental integration. Therefore, future research is expected to develop a web-based system with a centralized database.

the effect of deep breathing relaxation techniques on lowering blood pressure in elderly people in Bate Linteng and Lambunot Villages, Aceh Besar. This quantitative study used a pre-experimental design using a one-group pretest-posttest. The study was conducted from August 26 to August 31, 2024, with a population and sample of 16 elderly respondents with a history of hypertension. Data collection was conducted through observation using an observation sheet and the provision of deep breathing relaxation techniques. The results showed that the average blood pressure before the intervention was 148/90 mmHg with a standard deviation of 9.674, while after the intervention, it decreased to 143/87 mmHg with a standard deviation of 9.050. The statistical test results using the Paired Sample t-Test showed a significance value of 0.000 (p < 0.05), indicating a significant effect between deep breathing relaxation techniques and blood pressure reduction. The results of this study are expected to provide information for hypertension sufferers and their families that deep breathing relaxation techniques are a form of non-pharmacological therapy that can be performed independently to control blood pressure.
