Universitas Gadjah Mada Drinking Water Supply System (UGM-DWSS) Potential on Supporting Green Campus Program in Universitas Gadjah Mada

Abstract

Green Campus is a campus environment that is designed to increase energy efficiency, preserve resource and improve the quality of the environment. One of the important elements to support the green campus program is the existence of drinking water supply system.Universitas Gadjah Mada Drinking Water Supply System (UGM-DWSS) is a drinking water or potable water supply service to supply drinking water for the campus. This research aims at analyzing UGM-DWSS potential and its performance to support Green Campus. This research was based on primary data collection in UGM campus. Data collection techniques consist of observation of UGM-DWSS facilities, interview with UGM-DWSS water managers and users, and questionnaires distribution to UGM academic community. The daily water production of UGM-DWSS was 10 l/s drinking water. Every day the water discharge distributed from UGM-DWSS to 49 water fountains and 12 water dispensers was1.71 l/s, while the estimated daily water consumption rate was0.07l/s. It is assumed that those who did not consume water from UGM-DWSS facilities bought plastic drinking water bottle. Every day, it is estimated that the number of generated plastic drinking water bottle waste was 19,168 bottles with capacity 600 ml/bottle. Indeed, by comparing to the total water production capacity being produced daily, the idle capacity was 99.3 %.The tendency of negative response from the majority of UGM inhabitants for using UGM –DWSS was due to hesitation about water quality, continuity of water supply, and ease of access to the nearby water fountains and water dispensers. Improvement of UGM-DWSS facilities that are supported by massive socialization programs including innovation to utilize produced drinking water is recommended to optimize the role of UGM-DWSS to create Green Campus.

Assessment of Knowledge, Attitude and Practice towards Sustainability Aspects among Higher Education Students in Qatar

“…Such initiatives can improve individuals' values and guarantee the development of sustainability practices within society [76]. GC initiatives raise sustainability awareness in universities among participants in their implementation of sustainability practices, for instance, through environmentally friendly technology and energy efficiency management, which direct their behavior toward the sustainability [77,78]. It was verified that applying sustainability strategies at universities helps students obtain more knowledge and realize the importance of sustainable development.…”

Implementation of real-time image processing on bacterial cellulose formation using soybean-boiled wastewater with the variation of carbon sources during fermentation

“…The BC medium was composed of coconut water and soybean-boiled wastewater in a ratio of 70:30 with a total volume of 2.5 L [14]. The other constituent components were carbon sources (10% glucose [30], 5% sucrose [6], or 0.83% mannitol [31]), 0.2% ammonium sulfate [30], 0.2% acetic acid [30], and 20% starter [32].…”

“…The most commonly used BC formation medium is coconut water [6,7,8]. Furthermore, wastewater can also be used as a BC formation medium, such as liquid waste from sugarcane processing during the jaggery [9], juice from Japanese pear, orange, apple, grape, and pineapple waste [10], waste beer yeast [11], rice wine distillation wastewater [12], liquid waste from tofu production [13], and soybean-boiled wastewater from tempeh production [14]. In addition, Maloringan et al [14] used soybean-boiled wastewater as a BC formation medium because it contains nitrogen used by bacteria as a source of nutrients during fermentation.…”
