3.2 Implementing the 12 Principles of Green Engineering
in Universitas Gadjah Mada
The Universitas Gadjah Mada waste management system has applied the green engineering principle to support sustainable development. The implementation of the 12
principles of green engineering is expected to reduce the impact of waste generation
on environmental damage and the potential danger to human health. The implementation of the green engineering principle must also consider financial factors or
economic feasibility from input to system output. The academic community also
has an important role in implementing and monitoring matters that affect the waste
management system. Table 1 shows the implementation of the green engineering
principles at Universitas Gadjah Mada.
3.3 Examples of Assessments GreenMetric
Universitas Gadjah Mada technically has not followed the GreenMetric UI rating
system, but based on the guideline of the Universitas Gadjah Mada assessment system
can find out the magnitude of the sustainability score of the green campus program
on existing conditions. UI GreenMetric has six parameters or categories to assess the
sustainability of the green campus program and one of them is the problem of garbage.
The waste parameter has six indicators consisting of a program or campus policy
regarding waste generation and recycling, processing of organic and inorganic waste,
handling of toxic waste, and liquid waste disposal. The indicator of campus waste
assessment has a total value of 18% of the total parameters (Sari 2018). Assessment
of waste management systems at Universitas Gadjah Mada can be seen in Table 2.
Based on the results of interviews and research, Universitas Gadjah Mada has
a total value/weight of 10.50% of a maximum weight of 18%. With this score, the
sustainability of the waste management system is considered quite good.
a. Recycling program for university waste
Universitas Gadjah Mada has a campus waste recycling program and can handle up
to 50% of the waste generated in the campus area. In supporting the campus waste
recycling program, in 2014 Universitas Gadjah Mada has a Standard Operational
Procedure for handling waste from the depot to the place of processing and final
waste disposal. The waste that is recycled by Universitas Gadjah Mada is organic
waste which mostly comes from leaf waste. The collected leaf waste is then processed
at the House of Recycling Innovation, Universitas Gadjah Mada’s Agro Technology
Innovation Center (PIAT) into organic fertilizer through the composting method. In
addition to leaf waste, PIAT also has plastic waste processing technology, especially
those derived from used plastic bottles in the form of pyrolysis. Pyrolysis results in
the form of fuel can be used as additional energy or energy to run incinerators.
