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.
