摘要: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.
