Abstract

Decentralization has emerged as a significant trend in forest governance across Southeast Asia, aiming to enhance local participation and improve resource management. While intended to empower local communities, the actual impacts of decentralization on forest governance remain poorly understood. This study investigates how decentralization affects governance structures, stakeholder engagement, and environmental outcomes in the region. The research aims to assess the effects of decentralization on forest governance by examining case studies from selected Southeast Asian countries. The study seeks to identify both positive and negative outcomes, focusing on how local governance influences forest conservation and management practices. A mixed-methods approach was utilized, combining qualitative interviews, surveys, and document analysis. Data were collected from government officials, local community members, and NGOs involved in forest management. Comparative analysis of case studies from Indonesia, Malaysia, and the Philippines provided insights into the varying impacts of decentralization. Findings indicate that decentralization can enhance local participation and accountability in forest governance. However, challenges such as inadequate capacity, corruption, and conflicting interests often hinder effective implementation. Case studies revealed diverse outcomes, where successful decentralization led to improved resource management, while in other instances, it exacerbated existing inequalities. The research highlights the complex relationship between decentralization and forest governance in Southeast Asia. Effective decentralization requires supportive policies, capacity building, and genuine stakeholder engagement to achieve sustainable forest management. The study underscores the need for ongoing evaluation of decentralization processes to ensure they meet both conservation and community objectives effectively.

Abstract

Teacher burnout is a pervasive challenge in education, negatively affecting both educators’ well-being and student outcomes. Psychological capital, encompassing hope, self-efficacy, resilience, and optimism, has emerged as a critical protective factor against occupational stress. Understanding how specific components of psychological capital influence burnout can inform interventions aimed at promoting teacher well-being and sustaining instructional effectiveness. This study investigates the role of hope, self-efficacy, and resilience in preventing burnout among educators in primary and secondary schools. A quantitative research design was employed, involving 150 teachers selected through stratified random sampling. Participants completed standardized questionnaires measuring psychological capital dimensions and burnout levels. Statistical analyses, including correlation and multiple regression, were conducted to examine predictive relationships. Findings indicate that higher levels of hope, self-efficacy, and resilience are significantly associated with lower burnout scores. Among the components, self-efficacy exhibited the strongest protective effect, followed by resilience and hope. The study concludes that cultivating psychological capital is essential for mitigating teacher burnout, enhancing professional commitment, and promoting sustainable teaching practices.

Abstract

Non-linear differential equations constitute the mathematical foundation of complex physical, biological, and engineering systems, yet classical numerical solvers often suffer from prohibitive computational costs as system dimensionality increases. Quantum computation offers a promising pathway for accelerating such calculations, although existing quantum algorithms primarily address linear differential models and fail to generalize efficiently to non-linear regimes. This study aims to develop and evaluate a novel quantum algorithm designed specifically to approximate solutions to non-linear differential equations with a potential exponential speedup over classical methods. The proposed approach integrates a variational quantum ansatz with non-linear Hamiltonian embedding and amplitude encoding to capture non-linearity within a tractable quantum framework. Simulations were conducted on noisy intermediate-scale quantum (NISQ) models and idealized quantum circuits to benchmark accuracy, convergence behavior, and computational scaling. The results indicate that the algorithm achieves stable convergence across representative non-linear systems while demonstrating a significant reduction in computational complexity relative to classical solvers, particularly for high-dimensional models. The study concludes that the proposed algorithm represents a viable direction for quantum-enhanced numerical analysis and may serve as a foundation for future quantum solvers targeting complex dynamical systems.

Abstract

The coupling of superconducting qubits with spin ensembles has emerged as a promising solution to bridge the microwave-optical frequency gap in hybrid quantum systems. These systems are crucial for advancing quantum communication, quantum networks, and integrated quantum technologies. However, achieving coherent coupling between these two platforms remains a significant challenge due to the differences in their operational frequency regimes and their susceptibility to decoherence. This research aims to explore the coherent coupling between a superconducting qubit and a spin ensemble, specifically focusing on its potential for efficient microwave-to-optical transduction. The primary objective of this study is to develop a hybrid quantum system that enables the transfer of quantum information between microwave and optical domains with minimal loss of coherence. Experimental and theoretical approaches were used, involving superconducting qubits and nitrogen-vacancy (NV) centers in diamonds as the spin ensemble. The results demonstrate that the coupling mechanism is efficient, achieving high transduction efficiencies and long coherence times, particularly at optimized coupling strengths. These findings suggest that the hybrid system can be used for scalable quantum communication systems, facilitating quantum information transfer across different frequency domains. In conclusion, this study provides a robust method for microwave-to-optical transduction, opening new avenues for quantum network development and hybrid quantum technologies.

Abstract

The increasing presence of persistent pharmaceutical contaminants in water bodies poses a significant threat to environmental and human health, necessitating effective remediation technologies. This study aimed to develop and evaluate zinc oxide/copper oxide (ZnO/CuO) composite thin films as an efficient photocatalyst for degrading pharmaceutical waste under visible light. The ZnO/CuO thin films were synthesized via a sol-gel spin-coating method, and their photocatalytic activity was assessed using diclofenac as a model pollutant. The results demonstrated that the ZnO/CuO heterostructure exhibited enhanced visible light absorption and superior photocatalytic performance compared to pure ZnO. The composite films achieved over 90% degradation of diclofenac within 120 minutes, with the process following pseudo-first-order kinetics. The enhanced efficiency is attributed to effective charge separation at the ZnO/CuO interface. This research confirms that ZnO/CuO thin films are promising, reusable photocatalysts for the sustainable treatment of pharmaceutical-contaminated water.

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.
