This quantitative study employs Structural Equation Modeling (SEM) to investigate the intricate relationships between stakeholder participation, green supply chain management, urban forest management quality, and ecosystem service quality in Palangkaraya, Indonesia. Survey data collected from stakeholders engaged in urban forest management and environmental conservation efforts were subjected to Confirmatory Factor Analysis (CFA) to validate the measurement model. Path Analysis was then conducted to explore direct and mediated effects, with a focus on the mediating role of urban forest management quality as assessed through SEM. The findings reveal significant positive relationships between stakeholder participation, green supply chain management, urban forest management quality, and ecosystem service quality. Notably, urban forest management quality emerges as a mediator between stakeholder participation and ecosystem service quality, as well as between green supply chain management and ecosystem service quality. This study contributes to the empirical understanding of urban environmental management dynamics, offering insights that can inform policy and practice for promoting environmental sustainability and enhancing ecosystem service provision in Palangkaraya.

This study aims to explore the interrelationships between Green Open Spaces, Ecological Patterns, the Ecological Supply Chain, and Environmental Sustainability in urban ecosystems. A quantitative research approach employing a cross-sectional design was utilized. Data were collected through surveys and field observations from urban residents with access to green spaces. Structural Equation Modeling (SEM) with Smart PLS was used for data analysis. The findings indicate significant impacts of Green Open Spaces and Ecological Patterns on both the Ecological Supply Chain and Environmental Sustainability. Moreover, the Ecological Supply Chain mediates the relationship between Green Open Spaces/Ecological Patterns and Environmental Sustainability. Limitations include the focus on a specific geographical area and potential biases in self-reported data. This study contributes to ecological theory by emphasizing the interconnectedness between ecological elements and their influence on Environmental Sustainability. Practically, it provides insights for urban planning and conservation efforts, highlighting the importance of preserving natural habitats within urban environments. The findings also underscore the need for holistic approaches to ecosystem management and sustainability. The novel aspect of this study lies in its examination of the mediating role of the Ecological Supply Chain in the relationship between ecological elements and Environmental Sustainability, offering new insights into the mechanisms driving ecosystem dynamics in urban settings.

Currently, school sustainability is the focus of attention of all parties, including education quality management experts, which is related to schools' weaknesses in using big data and artificial intelligence (AI). The aim of this research is to analyze the role of using big data and AI in improving the quality of education quality management in Indonesia and its impact on school sustainability. The research design uses a quantitative approach, especially correlational, verification or hypothesis testing based on empirical data in the field. The research population was all teachers, principals and high school supervisors in Palangkaraya City, Central Kalimanan, totaling around 5,423 people. The sample size used the Hair formula and obtained a sample size of 178 people. Data was collected using a questionnaire which was distributed to selected samples using a Google form. Primary data was analyzed using SMART PLS. The results shows that the use of big data had an impact on the quality education management, it also has an impact on school sustainability, while artificial intelligence had an impact on the quality education management, it also had an impact on school sustainability, In addition, quality education management had an impact on school sustainability and it mediated the relationship between the use of big data and school sustainability, and finally, quality education management mediated the relationship between artificial intelligence and school sustainability.
