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 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.

reflects religious rituals but also embodies historical, cultural, and spiritual values that shape the identity of the local community. This study aims to examine the tradition of visiting the tomb of Sultan Maulana Hasanuddin of Banten as a cultural heritage and a manifestation of the community’s spirituality. The research method employed is a qualitative approach using literature review and archival research. Data were obtained from historical books, scientific journal articles, theses, research reports, and other relevant supporting sources related to the study of pilgrimage, local Islamic culture, and the Sultanate of Banten. Data analysis was conducted using a descriptive-qualitative technique by examining and interpreting various sources to uncover the meanings, practices, and dynamics of the pilgrimage tradition. The results of the study indicate that the tradition of visiting the tomb of Sultan Maulana Hasanuddin possesses a strong spiritual dimension as a means of drawing closer to Allah, a medium for self-reflection, and the formation of individual and collective spirituality. Furthermore, the pilgrimage tradition also functions as an intangible cultural heritage that plays a role in preserving history, transmitting cultural values, and strengthening the identity of the Banten community. Amid the development of religious tourism and modernization, the pilgrimage tradition faces dynamics that require sustainable management to ensure that religious and cultural values remain preserved. This study concludes that the tradition of pilgrimage to the tomb of Sultan Maulana Hasanuddin of Banten is an important and relevant cultural-religious practice in maintaining the sustainability of the community’s spirituality and cultural identity.

roach with a survey method. Data collection was conducted using a questionnaire, with a total sample of 54 respondents. The data analysis technique applied was multiple linear regression analysis. The results show that (1) resilience has a positive and significant effect on adaptive behavior, (2) mindset has a positive and significant effect on adaptive behavior, and (3) resilience and mindset simultaneously have a positive and significant effect on adaptive behavior. Descriptive findings based on business type indicate that the highest levels of resilience and adaptive behavior are found in restaurant businesses, while relatively lower levels are observed in bakery and pastry industries. Based on business duration, entrepreneurs who have operated longer tend to demonstrate better adaptive capabilities compared to newer businesses. This study recommends enhancing digital literacy training, strengthening entrepreneurial mindset, and providing business mentoring programs to improve the adaptive capacity of MSMEs in facing digital transformation.

il servants at the Education and Culture Office of West Kalimantan Province, seen from the aspects of: Accountability, Responsibility, and Responsiveness. The results of the study indicate that Accountability, Responsibility, and Responsiveness are key elements in reflecting the quality of civil servant performance at the Education and Culture Office of West Kalimantan Province. However, in its implementation, these three aspects have not been running optimally. ASN accountability is still hampered by a lack of discipline in reporting and minimal transparency of work results. Responsibility is also not fully reflected in ASN's commitment to carrying out duties and responsibilities professionally. On the other hand, responsiveness to community needs, especially in the fields of education and culture, is still relatively slow, which indicates a lack of active involvement of ASN in absorbing and responding to public aspirations quickly and appropriately. This research recommends strategic steps to strengthen accountability through a more structured and regularly monitored performance reporting system. Improving accountability can be achieved through ongoing development, professional ethics training, and consistent enforcement of work discipline. To enhance responsiveness, a more participatory and adaptive public service mechanism needs to be developed to meet community needs.
Abstract:The purpose of this study is to describe and analyze the process of organizing, interpreting and applying the implementation process of the Active Emergency Village program in realizing community independence in Roban Village,…
llage, Singkawang City. The results of the study indicate that the Implementation of the Active Emergency Village program in Realizing Community Independence in Roban Village, Singkawang Tengah District, Singkawang City has been implemented but has not been maximized. This can be seen from the implementation of the organizing process that has not been carried out in accordance with the activities of selecting the administrators and cadres of the Active Emergency Village through a special meeting of the formal leaders of the Village and community leaders and several community representatives. The election was carried out through deliberation and consensus, in accordance with the applicable procedures and criteria, facilitated by the Roban Health Center. The implementation of the interpretation process of the implementation of the socialization process through the transmission or distribution of information is not clearly received by the implementers such as the village head and the health center, so that not all people know or understand the program. The implementation of the application process such as the adequacy of implementing personnel, authority as authority or legitimacy for implementers in implementing the established policies is still limited, so the power of the implementors in implementing the program in the eyes of the community is not in accordance with the Decree of the Minister of Health of the Republic of Indonesia, Number 1529 / MENKES / SK / X / 2010 Concerning General Guidelines for the Development of Active Emergency Villages and Sub-districts.

s well as its contribution to the achievement of SDG 13 (Climate Action) in coal companies listed on the Indonesia Stock Exchange during 2022–2024. This research employs a descriptive quantitative approach using secondary data obtained from sustainability reports. The sample consists of 17 coal companies selected through purposive sampling, resulting in 51 observations. Data analysis is conducted using content analysis with a dummy scoring method based on 17 indicators of the TCFD metrics and targets pillar. The results indicate that the level of environmental risk disclosure shows an increasing trend, from 37.71% in 2022 to 48.44% in 2024. However, the overall level remains moderate, indicating that companies are still in a transition phase toward more mature climate reporting practices. Basic indicators such as total emissions and Scope 1 and Scope 2 emissions are widely disclosed, while advanced indicators such as Scope 3 emissions and emission reduction targets remain limited. The findings also reveal that the contribution to SDG 13 is uneven: strong in providing baseline emission data, moderate in emission intensity efficiency, and weak in comprehensive inventory and long-term mitigation strategies. Furthermore, companies are categorized into three groups—best practice, intermediate, and resistant—based on their level of disclosure and EMA readiness. Companies with more developed EMA systems demonstrate stronger contributions to climate action. Overall, the study concludes that the coal sector shows positive but not yet optimal alignment with SDG 13, requiring improvements in methodological transparency, Scope 3 measurement, and science-based emission targets.

Abstract:Healthcare service quality is an important factor influencing patient satisfaction, particularly in pediatric nursing services in hospitals. The SERVQUAL model, which includes the dimensions of tangible, reliability, responsiveness,…
ponsiveness, assurance, and empathy, is widely used to evaluate healthcare service quality. This study aimed to analyze the relationship between service quality and pediatric patient satisfaction in the Bung Hatta Inpatient Ward of Tk III Dr. Reksodiwiryo Hospital, Padang. This study employed a quantitative approach with an analytic descriptive design and a cross-sectional method. The sample consisted of 30 respondents who were parents or guardians of pediatric patients hospitalized for at least three days. Respondents were selected using an accidental sampling technique. Data were collected using a SERVQUAL-based questionnaire with a Likert scale and analyzed using univariate and bivariate analysis with the Chi-square test at a significance level of 0.05. The results showed that the majority of respondents were satisfied with nursing services (80%). Bivariate analysis indicated significant relationships between the tangible (p=0.033), reliability (p=0.049), and assurance (p=0.040) dimensions and pediatric patient satisfaction. However, responsiveness and empathy dimensions were not statistically associated with patient satisfaction (p>0.05). In conclusion, nursing service quality is associated with pediatric patient satisfaction in several SERVQUAL dimensions, particularly tangible, reliability, and assurance. Continuous improvement in nursing service quality is necessary to enhance satisfaction among pediatric patients and their families in hospital settings.
