Green Engineering for Waste Management System …

feces originating from each building, uses an on-site wastewater treatment system.
Urine and feces flown toward the septic tank in each building, and in the septic tank,
there is a decomposition process by microorganisms.
4 Conclusion
Sustainability has three main pillars, namely economic, social, and environmental.
Green engineering and green architecture use these three pillars as the basis of the
concept whereby, in a system or process must have economic feasibility that can
maximize human welfare but still calculate risk factors for humans and the environment.
Green engineering has 12 principles that can be applied in the university to support
the sustainability of the campus waste management system as one of the green campus
programs and then can be assessed using the GreenMetric UI assessment method.
Universitas Gadjah Mada has implemented the 12 principles of green engineering
from the start of the preparation of the Standard Operational Procedure system for
managing campus waste to the selection of renewable waste processing technology
in accordance with the type of campus waste generation. Based on the GreenMetric
assessment method, Universitas Gadjah Mada has a sustainability score of 10.50%
from a total of 18%.
