This research explores the development of a participatory governance model for community based waste management systems, aiming to enhance both legal compliance and public social welfare outcomes. Community based waste management (CBWM) plays a critical role in addressing environmental and health challenges, yet its success is often hindered by weak governance structures, limited community involvement, and insufficient regulatory frameworks. The study introduces a governance model that integrates local community participation into decision making processes, encouraging ownership and responsibility among residents. The primary goal is to improve compliance with environmental regulations while promoting social welfare by fostering better public health and community cohesion. A review of literature highlights key theories of participatory governance, focusing on its ability to enhance legal adherence and increase social equity. Previous studies on CBWM demonstrate the potential of community involvement in overcoming barriers to legal compliance, such as weak enforcement and fragmented governance. However, challenges like inadequate infrastructure, socio economic factors, and cultural habits still impede full participation and compliance. The study utilizes a mixed methods approach, including stakeholder analysis, participatory workshops, and regulatory compliance assessments, to evaluate the effectiveness of the model. The results show that communities involved in participatory governance exhibit higher compliance with waste management laws, improved sanitation, and healthier living conditions. Furthermore, the model fosters social capital and community empowerment, contributing to long term sustainability. In comparison to centralized waste management systems, the participatory approach is found to be more adaptable, accountable, and socially accepted. While the model presents several benefits, challenges such as infrastructure limitations and cultural barriers remain. Future research should further investigate how to address these challenges, particularly through technological integration and cross sector collaborations, to ensure the scalability and sustainability of the participatory governance model.

This research is motivated by the suboptimal strategy of the Pangandaran Regency Tourism and Culture Office in supporting sustainable tourism development. Several problems identified include the lack of optimal management of facilities and infrastructure, such as waste management, and inadequate transportation facilities. Furthermore, tourism promotion has not been carried out in a sustainable and measurable manner, compounded by the absence of a Regional Promotion Agency. Human resources (HR) in the tourism sector also still lack a comprehensive understanding of the concept of sustainable tourism, which is a major challenge in implementing this policy effectively. The purpose of this study was to determine the strategies implemented by the Pangandaran Regency Tourism and Culture Office in developing sustainable tourism. The method used was descriptive qualitative with data collection techniques through observation, interviews, and documentation. Informants in this study consisted of government elements, communities, and tourism business actors. The results showed that the strategies implemented by the Pangandaran Regency Tourism and Culture Office encompass four dimensions of strategic management: environmental monitoring, strategy formulation, strategy implementation, and evaluation and control. However, the strategies that have been implemented have not been optimal. Several efforts have been made, including increased training based on local potential, technology education, the formation of promotional groups, and regular activity evaluations. However, major challenges remain: strengthening coordination between various stakeholders and improving natural resource management and more environmentally friendly supporting facilities. This study illustrates the need for strategic and policy adjustments to optimize sustainable tourism development in Pangandaran Regency, with a focus on increasing understanding and involvement of the community and businesses, as well as optimizing infrastructure and promoting more planned and measurable initiatives.

The purpose of this paper is to examine the role of Green Intellectual Capital (GIC) in the development of waste-to-energy (WtE) technologies, which is of special relevance for the incineration plants in the Gulf Cooperation Council (GCC) countries. Although previous studies have focused primarily on technological and infrastructural aspects, this paper investigates the contribution of intangible assets such as green human, structural, and relational capital towards the performance and sustainability of WtE systems. Adopting a mixed-method approach, the results show that Green Structural Capital has the first place in supporting operational efficiency, followed by Green Human Capital and Green Relational Capital. The statistical analysis based on Structural Equation Modeling (SEM) shows that all GIC dimensions are positively related to plant performance, with institutionalized knowledge and systems as the most significant enablers of innovation. Qualitative findings also highlight constraints such as lack of training, unhandy knowledge systems, and poor public-private interaction. The findings recommend policy suggestions for promoting GIC assimilation within environmental infrastructure and provide a region-based theoretical model connecting knowledge-based resources and sustainable waste management practices. The study emphasizes the importance of integrating intellectual capital into the strategic decision-making process of waste-to-energy plants to enhance their operational effectiveness and long-term sustainability. Additionally, the research underlines that fostering a knowledge-sharing culture and enhancing collaboration between various stakeholders, including governmental bodies, private firms, and research institutions, is critical for the success of green initiatives. Training programs aimed at developing green human capital and improving public-private partnerships are essential to overcoming the current barriers to innovation in the WtE sector. This study has practical and scholarly implications in unifying the focus from just technology to the facilitating role of human and intellectual capital in green transformation, further bridging the gap between environmental sustainability and technological advancements in waste management.

Bandung Regency, which is experiencing overcapacity in landfills, has implemented a waste management solution involving the separation of organic and inorganic waste. Inorganic waste, which is notoriously difficult to decompose, has prompted the Bandung Regency government to adopt a community-focused approach to waste management, establishing waste banks in school-age communities. However, the project has encountered challenges, as evidenced by the fact that some schools have implemented waste banks but have not been actively engaged in their operations. This has led to the project's suboptimal implementation in Bandung Regency schools.The objective of this study is to identify the challenges associated with the inactivity of waste banks in Bandung Regency schools, as perceived by students and administrators.The study utilises the triple drivers of ecopreneurship, focusing on the economic, social, and environmental benefits of school waste banks. This research employs a mixed methods approach, utilising both quantitative and qualitative data collection methods. The quantitative approach involves the administration of surveys to students, followed by data processing using descriptive statistics. The qualitative method involves conducting interviews with administrators, and the data is processed using the Miles and Huberman model. The findings of the research indicate that the implementation of a waste bank for the management of inorganic waste in a school environment is positively received by the school, despite the presence of obstacles related to waste collection sites, socialisation among students, and differences between administrators and students regarding the most significant focus or choice for implementing waste banks in schools.It is anticipated that the research results will contribute to the understanding of inorganic waste management in waste banks that are less active in the school environment. The study thus recommends further research in schools that are routine or active in waste bank implementation activities, with a view to describing overall information about the implementation of school waste banks, especially in schools in Bandung Regency with school waste bank projects.

This study evaluates the impact of an AI-driven nutritional monitoring system in hospital settings, focusing on its effectiveness in reducing food waste and improving the accuracy of dietary assessments.
