Abstract

The electrochemical reduction of carbon dioxide (CO?) is a critical strategy for mitigating climate change and producing value-added chemicals, yet the development of highly selective catalysts remains a primary challenge. This study aimed to conduct a rigorous comparative analysis of three distinct classes of "smart" catalysts—a molecular cobalt complex, a metal-organic framework (MOF), and a single-atom copper catalyst (Cu-SAC)—to elucidate the relationship between molecular design and lab-scale performance. The catalysts were synthesized, characterized via XRD and XAS, and evaluated for electrocatalytic CO? reduction in a flow cell reactor. The results showed that the Cu-SAC exhibited superior performance, achieving a Faradaic efficiency for ethylene (C?H?) exceeding 70% at a low cell voltage, significantly outperforming the MOF and molecular catalysts, which primarily produced CO and formate. This high selectivity was directly correlated with the optimized coordination environment of the isolated Cu sites. This comparative analysis confirms that rational design at the atomic level is a highly effective strategy for steering reaction pathways towards valuable multi-carbon products, providing a crucial benchmark for future catalyst development.

Abstract

Creative startups in Indonesia have become key players in the country's economic growth, contributing significantly to job creation and innovation. However, securing funding remains a major challenge for these startups. The gap in access to financing and the lack of understanding of investors about the creative sector often hinder the growth potential of these businesses. Despite the promising prospects, these challenges require a comprehensive analysis to identify the opportunities for overcoming funding barriers. This study aims to analyze the challenges faced by creative startups in Indonesia when seeking funding and explore the opportunities available to facilitate their access to capital. The research focuses on identifying key obstacles and evaluating potential solutions that could improve the startup ecosystem in the country. A mixed-methods approach was employed, combining qualitative interviews with creative startup founders and quantitative surveys conducted among investors and funding bodies. Data was analyzed to identify common challenges and potential opportunities within the funding landscape. The study found that limited awareness among investors, a lack of tailored financial products, and the perception of high risk associated with creative startups were the primary challenges. However, there are emerging opportunities, including government initiatives and the growing popularity of crowdfunding platforms, which are becoming viable alternatives for funding. To enhance the growth of creative startups in Indonesia, both government and private sectors must collaborate to provide more accessible and specialized funding options. Additionally, increasing awareness among investors about the potential of the creative sector can unlock new funding opportunities.

Abstract

Tropical peatland forests in Central Kalimantan, critical global carbon stores, are severely degraded and now act as major greenhouse gas sources due to drainage and fires. This study aimed to evaluate the ecological effectiveness and climate resilience of Assisted Natural Regeneration (ANR) for restoring the hydrological functions and biodiversity of these degraded ecosystems. A field experiment was established across 100 hectares, where the ANR method involved canal blocking to rewet the peat and selective planting of native pioneer species, monitored against control plots over five years. The results showed significant and rapid recovery. Canal blocking successfully raised the water table by an average of 40 cm, drastically reducing fire risk. Furthermore, native tree species richness in ANR plots was over 200% higher than controls, with canopy closure reaching 60%. ANR is highly effective, cost-efficient, and climate-resilient, providing a scalable model that prioritizes rewetting and facilitates natural successional pathways to restore critical ecosystem functions and secure long-term carbon storage.

Abstract

Avian influenza virus remains a significant threat to global public health, poultry industries, and food security due to its high transmissibility and zoonotic potential. Rapid and reliable detection is essential for early outbreak control, yet conventional diagnostic methods are often time-consuming, laboratory-dependent, and rely on labeled reagents, limiting their applicability in field and point-of-care settings. This study aims to develop a Bio-MEMS cantilever-based biosensor capable of rapid, label-free detection of the avian influenza virus with high sensitivity and specificity. An experimental Bio-MEMS approach was employed, involving microfabrication of silicon cantilevers, surface biofunctionalization with virus-specific recognition elements, and real-time mechanical sensing of virus–receptor interactions. The biosensor’s performance was evaluated by measuring cantilever deflection responses under controlled exposure to varying viral concentrations. The results demonstrate stable baseline behavior, low noise levels, and clear concentration-dependent deflection signals, achieving rapid detection within minutes and a low limit of detection without signal amplification. Non-target analytes produced negligible responses, confirming high specificity. In conclusion, the developed Bio-MEMS cantilever-based biosensor provides an effective platform for rapid, label-free detection of avian influenza virus. This technology shows strong potential for integration into portable diagnostic systems and could be adapted for surveillance of other viral pathogens.

Abstract

This study explores the evolving role of Qur’anic interpretation (tafsir) within the context of modernity and its significance for contemporary Islamic thought. Modern intellectual, social, and ethical transformations have generated new questions regarding the authority, methodology, and relevance of classical exegetical traditions, making tafsir a crucial site of engagement between revelation and changing realities. The objective of this research is to examine how tafsir functions as an intellectual mediator that enables Islamic thought to respond to modern epistemological and societal challenges while maintaining continuity with the Qur’anic tradition. The study employs a qualitative research design based on textual and interpretive analysis of selected classical and contemporary tafsir works that explicitly engage with modern issues. Hermeneutical and conceptual frameworks are used to analyze interpretive patterns, methodological orientations, and thematic emphases. The findings reveal that contemporary tafsir demonstrates significant methodological diversity, with a growing emphasis on contextualization, ethical reasoning, and thematic interpretation. Tafsir emerges not as a static tradition but as a dynamic intellectual practice that actively shapes modern Islamic discourse. The study concludes that tafsir plays a central role in negotiating the relationship between Islam and modernity, serving as a bridge between sacred text and contemporary thought.

Abstract

Background. In contemporary societies, cultural traditions face constant pressure from globalization, modernization, and social change. These forces often lead to the adaptation and transformation of cultural practices, creating a dynamic tension between tradition and progress. Understanding how communities navigate these transitions is critical for understanding the mechanisms of cultural preservation and transformation. Purpose. This study aims to examine the processes of cultural adaptation and social change in contemporary communities. By investigating how communities balance the preservation of traditions with the demands of modern life, the research seeks to shed light on the factors influencing cultural evolution and the impact of social change on traditional practices. Method. A qualitative research approach is employed, utilizing in-depth interviews and participant observation within several communities undergoing significant cultural transitions. Data is collected from various social groups, including older and younger generations, to explore differing perspectives on tradition and change. Results. The study finds that while traditional practices remain important, they are continually reinterpreted and adapted to align with modern values and lifestyles. Younger generations tend to prioritize aspects of tradition that align with global trends, while older generations emphasize the preservation of original practices. Conclusion. This research underscores the complexity of cultural adaptation and highlights the role of intergenerational dialogue in negotiating the tension between tradition and change.
