To depict detailed sustainability efforts that have been implemented in campus environments, research was conducted at the Universitas Diponegoro (UNDIP), a leading green campus in Indonesia. The aim of the current study was to explore how sustainable development has been conducted by UNDIP and to identify factors that may indicate the existence of sustainability activity in higher-education institutions (HEIs). Factors affecting sustainability implementation in HEIs were derived using bibliometric analysis. Information on the implemented strategies to maintain the sustainability of HEIs was obtained via a closed questionnaire to 40 relevant experts, and analyzed using strengths, weaknesses, opportunities, and threats (SWOT) analysis, and quantitative strategic-planning matrix (QSPM) analysis. Institutional commitment to sustainability and guidance to implement sustainability in HEIs were found to have the highest scores with regard to internal and external factors. The respondents selected more aggressive strategies for the enhancement of sustainability implementation at UNDIP. Fostering external collaboration should be a priority for UNDIP since this can provide mutual benefits and significant improvement towards achieving Sustainable Development Goals (SDGs). The current study provides a robust self-assessment method for selecting appropriate strategies to maintain HEI sustainability.

Effective solid waste management strategies are recognized as efforts to achieve campus sustainability. The university campus is currently considered the center of various activities involving students, lecturers, staff, and other parties contributing to the consumption pattern of energy, water, and other resources. This study aims to estimate the quantity and compositions of waste generated on the Universitas Diponegoro (UNDIP) campus, identify the causes of waste generation, evaluate the relationships between variables through statistical analysis, and recommend possible strategies to reduce solid waste generation. The results show that the simultaneous contribution of the student-gender ratio, student awareness level, administrative staff background, and green space amounted to 67.7% of the waste generation at UNDIP. Therefore, these four factors need to be a concern for campus authorities in their efforts to handle campus waste. Student awareness in particular was determined to be the only factor that significantly affects solid waste generation. UNDIP may implement proper environmental education through sustainability courses in each faculty to reduce solid waste in higher education institutions since it has the most significant impact. Outcomes of this study could be used as a reference to develop sustainable campus strategies, recycling plans, and comprehensive waste management in higher education.

The purpose of this research is to process a mixture of paper waste and garden waste based on material flow analysis and to analyze parameters based on parameters of water content, ash content, heating value, along with Thermogravimetry Analysis (TGA)/Derivative Thermogravimetry (DTG). The garden...
