Abstract

Food waste poses a serious environmental challenge that requires not only conceptual awareness but also practical sustainability competencies. This study aims to profile vocational high school students sustainability literacy in the skills domain of food waste education as a preliminary step toward developing interactive learning media. A total of 36 Grade X students in Bogor participated in a field trial using a prototype e-book entitled Awas Food Waste. Students were assigned to solve a contextual case, design digital posters, and present their solutions in class. Poster texts (365 words) were analyzed through word-frequency techniques, while oral presentations were assessed using a rubric adapted from Murray and Cotgrave. Results showed that frequently used terms indicated both problem recognition (e.g., sisamakanan [food leftovers], food waste, sampah [waste]) and proposed solutions (e.g., kompos [compost], maggot, organik [organic]). The presentation scores averaged 3.53 (median = 3; mode = 3), categorized as sufficientgood, with 22.2% of students achieving a very good level. These findings reveal that students are able to identify and communicate practical strategies to reduce food waste, although the depth and innovation of solutions remain limited. The study highlights a gap between awareness and applied action, underscoring the importance of scaffolding through interactive e-books and other digital media. This preliminary evidence serves as a baseline for designing pedagogically grounded interventions to strengthen vocational students sustainability skills and foster responsible environmental behavior

Abstract

Aims: This study aims to improve waste bank activities in Medan and make them more efficient Methodology and Results: The study involved the collection of secondary and primary data. The secondary data collected involved a general description of the study area, number, status, and location of the waste bank. Primary data included interviews and field research on selected waste banks. Importantly, survey and data collection were conducted from December 2017 to April 2018. A semi-structured interview survey approach was conducted to collect the data. Using the Material Flow Analysis (MFA) methodology, the findings of the study showed that of the total amount of the input material, 87.4 % is a recyclable waste and 12.6 % water. Also, the waste bank activities generate 87.2% recyclable items, 12.6% wastewater, and 0.2% residues. Conclusion, significance, and impact study: The findings are essential in understanding the use of resources to provide information for improving waste bank activities and waste management. Apart from the community, the government also plays a significant role in supporting the future of waste banks. This study found that waste bank activities are still conventional, with no technology adoption. In the future, the waste bank should be more efficient and manage large amounts of wastes, because the potential for recyclable products is still abundant.

Abstract

Indonesia is an archipelagic country consisting of more than 17,500 islands. Urbanization and community agglomeration in urban areas in Indonesia are increasing the complexity of solid waste management in Indonesia. The old paradigm of 'collect-transport-disposal' waste management still occurs frequently in cities in Indonesia. This research is designed to be a systematic qualitative review. The relationships between good environmental governance and sustainable solid waste management are synthesized from a perspective of current conditions in Indonesia. The solution to sustainable waste management is generally carried out through well-organized waste management in an integrated manner from upstream to downstream with a 'cradle-to-grave' mindset, including the impacts that may arise therein. Implementing sustainable solid waste management requires commitment and support from all aspects of stakeholders. Good environmental governance is a comprehensive, dynamic, and complex concept that attempts to improve environmental conditions while promoting sustainable solid waste management. The results show that good environmental governance is very influential for sustainable solid waste management, but it still needs to be implemented optimally in Indonesia. Integration and synchronization of policies between the central government and local government must be further improved to implement good environmental governance.

Abstract

This study employed a mixed methods design to analyse university students' knowledge of the Sustainable Development Goals (SDGs), their practices toward carbon reduction, and their innovative ideas for carbon mitigation. The main aim of this research is to examine how students’ understanding of the SDGs relates to their actual carbon reduction practices and to identify innovative solutions they propose for environmental sustainability. The research surveyed 123 students from 11 academic programs across seven universities in Eastern Indonesia. Quantitative results showed no significant differences in carbon reduction practices among students from various academic programs (F = 0.720; p = 0.674). A significant but very weak correlation was found between SDG knowledge and positive practices toward carbon reduction (r = 0.152; p = 0.047). The qualitative analysis identified eight themes of innovation, with a majority focusing on reforestation (33%) and the 3R waste management system (31%). Notably, technology-based ideas constituted only 8% of the responses. The study's main limitations include a sample imbalance, with 39.5% of participants from Environmental Engineering, and the use of convenience sampling, which necessitates caution when generalizing the findings. The results suggest the need for a holistic approach that integrates education, practical implementation, supportive facilities, and technological innovation. Recommendations include: (1) integrating SDGs into the curriculum, (2) developing a gamified, collaborative digital platform, and (3) fostering interdisciplinary collaboration to create contextual solutions

Abstract

A significant amount of global greenhouse gas (GHG) emissions comes from Indonesia, largely driven by deforestation and land degradation. As a developing nation, it is also dealing with the growing pressures of urban expansion. This study assesses the distribution of carbon stock in Parepare City, South Sulawesi, Indonesia. Notably, Parepare City has not yet experienced extensive land-use transformations, retaining substantial carbon stock, which positions it as a proactive case study for preventing future carbon loss amidst ongoing urbanization. Using the InVEST Carbon Storage and Sequestration model with SPOT 7 satellite imagery (2016) and global carbon density data, the research quantifies carbon storage across various land use/land cover (LULC) types. Analysis reveals natural ecosystems, particularly mixed forests and fields, hold the highest carbon storage potential. The total estimated carbon stock in Parepare City is 1,456,909.41 Mg C. These findings emphasize the urgent need for climate-responsive land management, including forest conservation, and urban greening, to enhance local carbon sinks and support Indonesia's climate change mitigation goals. This assessment provides crucial insights for urban planners and policymakers to balance growth with ecosystem conservation for a susta00inable future.
