Abstract

Community-based forest management (CBFM) has gained prominence as a strategy for sustainable forest governance in tropical Asia. This approach seeks to empower local communities, enhance biodiversity conservation, and improve livelihoods. However, the implementation of CBFM faces numerous challenges that can hinder its effectiveness. This research aims to identify the key challenges and opportunities associated with CBFM in tropical Asia. The study seeks to provide insights into the factors influencing successful implementation and to highlight best practices that can enhance community engagement in forest management. A mixed-methods approach was employed, combining qualitative interviews with community members, local officials, and NGOs, along with quantitative surveys of forest management practices. Case studies from selected countries in tropical Asia were analyzed to identify common themes and variations in CBFM implementation. Findings reveal that while CBFM has the potential to improve forest sustainability and empower communities, challenges such as inadequate capacity, lack of financial resources, and conflicting interests among stakeholders persist. Opportunities for enhancing CBFM include strengthening local governance structures, improving access to technology, and fostering partnerships with NGOs and government agencies. The study concludes that addressing the challenges of CBFM is essential for its success in tropical Asia. By leveraging the identified opportunities, stakeholders can enhance community participation and promote sustainable forest management. This research underscores the importance of an integrated approach that combines local knowledge with external support to achieve effective CBFM outcomes.

Abstract

Tropical forests are critical to global biodiversity and climate regulation. However, they face increasing threats from deforestation, climate change, and unsustainable land use practices. Ethnoforestry, the integration of indigenous knowledge and forest management practices, has emerged as a crucial component of both ecological and social resilience. Indigenous communities have long managed tropical forests using sustainable practices that ensure the balance of ecosystems while supporting local livelihoods. This research explores the role of ethnoforestry as a pillar of resilience in tropical forest regions. This study aims to investigate how ethnoforestry practices contribute to social and ecological resilience in tropical forests. Specifically, it seeks to understand the mechanisms through which indigenous forest management practices help mitigate environmental degradation and enhance community well-being. A qualitative approach was used, including field observations, interviews with indigenous forest managers, and analysis of case studies from tropical forest regions in Southeast Asia and Latin America. Data were analyzed using thematic analysis to identify key practices that promote resilience. The findings highlight that ethnoforestry practices, such as agroforestry, selective logging, and forest regeneration, contribute significantly to both biodiversity conservation and social cohesion. These practices foster sustainable resource use, mitigate environmental degradation, and enhance the adaptive capacity of communities. Ethnoforestry plays a vital role in enhancing the resilience of both ecosystems and human communities in tropical forests. Integrating indigenous knowledge into forest management strategies is essential for achieving long-term sustainability.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are vital for economic growth in many developing countries, including Indonesia. However, these businesses face significant challenges related to management inefficiencies, limited access to resources, and lack of technological adoption. This study aims to develop a cloud-based Management Information System (MIS) specifically tailored for MSMEs. The system is designed to improve operational efficiency, enhance decision-making, and facilitate better management practices for MSMEs in Indonesia. The research utilizes a design and development approach, incorporating both qualitative and quantitative methods. Data was collected through surveys and interviews with MSME owners and managers to identify their needs and challenges. The MIS was then developed using cloud computing technologies and tested with a sample of MSMEs. The cloud-based MIS successfully streamlined key management processes such as inventory tracking, financial management, and customer relationship management. Users reported increased operational efficiency, easier data access, and better decision-making capabilities. The system proved scalable, allowing MSMEs of different sizes and sectors to benefit from the technology. The study concludes that cloud computing-based MIS can significantly improve the management processes of MSMEs, contributing to their growth and sustainability.

Abstract

Indonesia faces a severe prison overcrowding crisis, with national overcapacity rates often exceeding 200%. Restorative Justice (RJ) has been formally adopted as a primary policy response, yet its empirical effectiveness as a large-scale diversionary tool to mitigate this crisis remains unverified. This study aimed to quantitatively analyze the effectiveness of RJ implementation in reducing new prison admissions and slowing the growth of total carceral populations in Indonesian jurisdictions. A quasi-experimental, comparative interrupted time-series (ITS) design was employed. Aggregate panel data from 40 matched jurisdictions (20 High-RJ implementation, 20 Low-RJ control) were analyzed over a 120-month period (2015-2024). A fixed-effects regression model was used to isolate the policy’s impact. -Implementation RJ jurisdictions showed significantly slower carceral population growth (9.1%) compared to Low-Implementation controls (38.4%). The regression analysis confirmed a robust, negative relationship between RJ diversions and new prison admissions (B = -0.81, p < .001), demonstrating a near one-to-one substitution effect. The findings provide strong quantitative evidence that RJ is an effective, data-driven policy for mitigating prison overcrowding. The crisis persists not from a lack of a solution, but from a failure of consistent implementation, which must be standardized to realize its full potential.

Abstract

Digital technologies have profoundly reshaped contemporary social life, altering patterns of interaction, identity formation, and cultural transmission across societies. From an anthropological perspective, these transformations cannot be understood solely through technical or economic explanations, but require attention to meaning, practice, and power embedded in everyday digital engagement. This study aims to analyze social transformation in the digital age by examining how technology functions as a culturally embedded social environment that mediates relationships, values, and symbolic expression. The research employs a qualitative design grounded in interpretive anthropology, combining digital ethnography, semi structured interviews, and analysis of online cultural artifacts to capture lived experiences within hybrid online offline spaces. The findings reveal that digital platforms reconfigure social organization, redistribute cultural authority, and intensify reflexive identity practices while simultaneously sustaining elements of cultural continuity. Digital interaction emerges as a site of negotiation where tradition and innovation intersect rather than as a force of unilateral disruption. The study concludes that social transformation in the digital age is best understood as a dynamic and context dependent process shaped by human agency and cultural interpretation. These results highlight the continued relevance of anthropological approaches for interpreting technological change and offer insights for research on digital society.
