Abstract

It is estimated that the amount of water needed by Universitas Diponegoro will increase in the years to come. Several efforts are required to ensure the fulfillment of water needed while also considering its sustainability. There have been studies on water conservation at the industrial level. Still, limited studies have discussed this problem in Indonesia specifically at university level. Therefore, this study discusses the water conservation program at Universitas Diponegoro that might be used as a reference for other universities to address water supply problems. This study aims to discuss in depth water conservation efforts at Universitas Diponegoro. This study incorporates a descriptive-qualitative approach along with direct observation. Some programs on water supply have been implemented in Universitas Diponegoro such as conservation, treated water consumed, water recycling and water-efficiency. The existence of rainwater harvesting tanks (RWH), reservoirs, biopores, wastewater treatment plans (WWTPs) and ponds are among the efforts that have been applied at Universitas Diponegoro in order to conserve the water. To date, Universitas Diponegoro has successfully conserved more than 75% of the water, recycling about >50% of wastewater, installing about >50% of water-saving equipment, and has treated clean water into drinking water using reverse osmosis.Keyword: water, conservation, sustainability, campus

Abstract

This study aims to analyse the potential energy that can be generated from municipal solid waste (MSW) at Tamangapa landfill, check the adequacy of energy according to the target of 20 MW/day, and give consideration to WtE technologies that can be applied. The research began with a literature study, followed by a quantitative approach to calculate the potential energy that can be generated through incineration, gasification, pyrolysis, anaerobic digestion (AD) and fermentation WtE technologies. The results showed that the energy target of 20 MW/day from MSW in Makassar can be met through incineration (168.80 MW/day), gasification (28.29 MW/day) and pyrolysis (62.03 MW/day). However, if 20 MW/day is clean energy, then considering the energy conversion efficiency, 30.38 MW/day is obtained for incineration, 7.07 MW/day for gasification, and 15.51 MW/day for pyrolysis. Based on this calculation, only incineration technology can fulfil the 20 MW/day energy target as expected. In order to maximise the energy potential, it is recommended to use a combination of incineration WTE technologies for plastic, rubber, paper and fabric components, and pyrolysis for wood and food waste components.

Abstract

This study provides a bibliometric review based on 1,891 Scopus-indexed records to integrate the trends and conceptual framework discussed in environmental accounting and corporate disclosure research. The results show intensive research growth since 2015, mainly led by Chinese, American, and Australian authors. Three categories were generated through thematic analysis: environmental strategies, corporate social responsibility, and accountability modes. Environmental accounting has developed from reporting to a strategic management tool, which is closely related to corporate governance, reputation, and sustainability performance. Additional findings show that the strength of international collaboration networks has increased over time, especially with Chinese and European institutions, reflecting a trend towards increasingly globalized research collaboratives. The keyword co-occurrence map indicates a shift in research priorities, from early attention to environmental cost accounting to the latest emphasis on climate-related disclosure, ESG integration, and low-carbon transition strategies. It also shows an increasing academic focus on regulatory drivers, including IFRS S2, the EU CSRD, and national emission policies. The cross-cluster comparison of differences implies a growing similarity in environmental responsibility accounting, corporate strategy, and stakeholder expectations, which underlines a move towards more consistent and decision-useful sustainability reporting systems.

Abstract

This review is the first attempt to integrate natural and anthropogenic drivers of coastal subsidence, the evolution of monitoring techniques, and geo-environmental impacts, with a focus on coupled human-environment systems. This review compares traditional geodetic techniques (levelling, GNSS) with other satellite and geophysical methods (InSAR, LiDAR, microgravity, and seismic survey) and assesses subsidence monitoring under different geo-environmental conditions. Empirical evidence from the northern coastline of Java, in particular Semarang, shows that subsidence has occurred at an annual rate of 2–10 + cm, which is directly linked to groundwater exploitation, alteration of land use, and coastal construction, which exacerbates tidal flooding, coastal recession, saltwater encroachment, ecosystem destruction, infrastructure deterioration, and social impacts. The findings suggest that subsidence is a unique geophysical phenomenon and not a result of anthropogenic interactions with natural systems involving water, land use, coasts, and public administration frameworks. This type of integration is essential for improved risk assessment, resilience, and sustainable development.
