Abstract

Dengue fever is a significant global health threat, where rapid and accurate diagnosis is crucial for timely clinical intervention and outbreak management. Conventional diagnostic methods are often centralized, time-consuming, and require sophisticated equipment, limiting their utility in point-of-care (POC) settings. This study reports the development and validation of a novel lab-on-a-chip (LoC) device integrating gold nanosensors for the ultrasensitive electrochemical detection of the Dengue virus non-structural protein 1 (NS1). The microfluidic device was fabricated using soft lithography, and the gold electrode surfaces were functionalized with specific anti-NS1 monoclonal antibodies. Detection was performed using differential pulse voltammetry (DPV), measuring the change in current response upon immunocomplex formation. The developed immunosensor exhibited a wide linear dynamic range and an exceptionally low limit of detection (LoD) of 1.5 pg/mL for the NS1 antigen. Furthermore, the device demonstrated high selectivity against other interfering proteins. Our findings successfully establish a robust, miniaturized LoC platform for the rapid and highly sensitive detection of dengue biomarkers. This device holds significant potential as a powerful POC diagnostic tool for the early detection of dengue fever, particularly in resource-limited environments.

Abstract

This study explores the comparative approaches to epistemology and ethics within Islamic philosophy and Western thought. Despite centuries of intellectual exchange, the two traditions are often studied in isolation, with minimal attention given to their intersections. Islamic philosophy emphasizes the integration of divine revelation and reason in acquiring knowledge, whereas Western thought traditionally prioritizes empirical evidence and rationalism. In ethics, both traditions share concerns regarding virtue and moral conduct but diverge in their foundations, with Islam grounding ethics in divine will and Western thought emphasizing human reason. The objective of this research is to compare these philosophical traditions, identifying both their points of convergence and divergence in epistemology and ethics. A qualitative research design is employed, focusing on textual analysis of key philosophical works from both traditions, including those of Avicenna, Al-Ghazali, Ibn Rushd, Plato, Aristotle, Kant, and Mill. The findings reveal significant differences in how each tradition understands the nature of knowledge and morality, yet also highlight areas of overlap, particularly in virtue ethics. This study contributes to the broader discourse by promoting a comparative framework for understanding the similarities and differences between Islamic and Western thought. It concludes by emphasizing the potential for cross-traditional dialogue to enrich contemporary philosophical inquiry.

Abstract

Rapid urbanization in Southeast Asia has exerted unprecedented pressure on water resources, leading to inefficiencies, resource depletion, and challenges in maintaining water quality. Conventional water management approaches often struggle to meet dynamic demand patterns and respond to infrastructure constraints, limiting sustainable urban water governance. This study aims to evaluate the role of artificial intelligence-driven predictive analytics in enhancing water resource management by forecasting demand, detecting system vulnerabilities, and optimizing allocation strategies in rapidly growing urban regions. A mixed-methods research design was employed, integrating quantitative hydrological and consumption datasets with real-time sensor data, machine learning-based predictive modeling, and qualitative expert insights. Data were analyzed through scenario-based simulations, regression analysis, and cross-validation to assess predictive performance and operational effectiveness. Results indicate that AI-enabled predictive analytics significantly reduces non-revenue water from 32% to 19%, improves reservoir stability from 68% to 81%, enhances water quality indices from 74 to 88, and increases leakage detection from 45% to 78%. Case studies demonstrate the practical applicability of predictive alerts in proactive infrastructure management and resource optimization. The study concludes that AI-driven predictive analytics provides a transformative tool for sustainable urban water governance, enabling proactive, efficient, and adaptive management strategies in complex urban environments.

Abstract

Background. The rapid shift to remote learning has intensified concerns about digital inequality, traditionally understood as disparities in access to internet connectivity and devices. Emerging evidence indicates that access alone is insufficient, as differences in connectivity stability and device performance critically shape students’ ability to participate effectively in online learning environments. These developments call for a reconceptualization of inequality within the framework of Digital Divide 2.0. Purpose. This study aims to analyze the impact of connectivity stability and device quality on student engagement and learning effectiveness, and to conceptualize these disparities as multidimensional components of Digital Divide 2.0. Method. A mixed-methods research design was employed involving 312 students from diverse educational contexts. Data were collected through structured surveys, objective connectivity tests, device quality assessments, and qualitative interviews. Quantitative data were analyzed using descriptive and inferential statistics to examine relationships and interaction effects, while qualitative data were analyzed through thematic coding to capture student experiences. Results. The findings indicate that connectivity stability is a strong predictor of student engagement, while device quality significantly influences learning effectiveness. Interaction effects demonstrate that combined limitations in connectivity and device performance produce compounded disadvantages in learning outcomes. Qualitative insights further reveal that students facing unstable connections and low-performing devices experience frustration, reduced participation, and limited access to interactive learning opportunities. Conclusion. Digital inequality in remote learning is multidimensional and extends beyond access to include quality-based disparities in connectivity and devices. Addressing Digital Divide 2.0 requires comprehensive strategies that integrate improvements in digital infrastructure with access to adequate technological resources. Policymakers and educators are encouraged to adopt holistic interventions to ensure equitable and effective remote learning environments.

Abstract

Green accounting and sustainable finance have emerged as critical tools for promoting environmental sustainability and economic growth. Tax incentives are increasingly recognized as a key mechanism to encourage businesses to adopt green accounting practices and invest in sustainable projects. However, the effectiveness of tax incentives in driving sustainable finance remains underexplored, particularly in developing economies where environmental regulations are still evolving. This study aims to examine the role of tax incentives in promoting green accounting and sustainable finance, providing insights into how fiscal policies can support environmental sustainability. A quantitative research design was employed, utilizing data from 200 companies in Indonesia. Multiple regression analysis was used to analyze the relationship between tax incentives, green accounting practices, and sustainable finance indicators, such as green investments and carbon footprint reduction. The findings reveal that tax incentives significantly enhance green accounting practices and sustainable finance. Companies benefiting from tax incentives reported higher levels of green investments and greater reductions in carbon emissions. The study also found that firm size and industry type moderate this relationship, with larger firms and those in environmentally sensitive industries showing stronger responses to tax incentives. This study highlights the importance of tax incentives in driving green accounting and sustainable finance. The results suggest that policymakers should design targeted tax policies to encourage businesses to adopt environmentally sustainable practices and contribute to global sustainability goals.

Abstract

Zakat, one of the five pillars of Islam, is a mandatory form of almsgiving aimed at redistributing wealth and promoting economic justice. In Indonesia, the world’s largest Muslim-majority country, zakat has the potential to significantly impact income distribution and reduce poverty. However, its effectiveness is often hindered by inefficiencies in collection, distribution, and utilization. This study examines the impact of zakat on income distribution in Indonesia, focusing on its role in reducing economic inequality and promoting social welfare. The research aims to identify the challenges and opportunities associated with zakat management and propose strategies for enhancing its effectiveness. Using a mixed-methods approach, this study combines quantitative analysis of income distribution data with qualitative interviews with zakat institutions, beneficiaries, and policymakers. Data were analyzed to assess the impact of zakat on poverty alleviation, income inequality, and economic empowerment. The findings reveal that zakat has a modest but positive impact on income distribution, particularly in rural areas. However, inefficiencies in collection and distribution, as well as a lack of transparency, limit its potential to achieve broader economic justice. The study concludes that improving zakat management through better governance, transparency, and targeted distribution strategies is essential for maximizing its impact on income distribution. This research contributes to the discourse on Islamic economics by providing practical recommendations for enhancing the role of zakat in promoting economic justice and social welfare in Indonesia.
