Pengolahan Sampah di Perguruan Tinggi dan Kontribusinya Terhadap Penurunan Emisi Gas Rumah Kaca
2016
The increasing of student number over the past four years urged Surabaya University to develop campus
facility that could serve as a learning media for the academic community in the campus and the community
around campus. The proposed facility was composting area. Composting area construction was necessary
because the accretion of students would be followed by the growing of solid waste generation. The estimation
of solid waste that be carried to composting area had not been done before. This research was conducted
with the aim of: 1. Estimating the quantity of solid waste generation that disposed to composting area 2.
Calculating the greenhouse gas reduction that can be achieved by solid waste composting. Solid waste
estimation was done before separation process in the composting area. Research was done by survey and
observation. Survey area was engineering faculty. Sampling for solid waste estimation was undertaken at
TG building. The results indicated that 70 % of the solid waste was anorganic waste and solid waste
generation was 25-50 kgs daily. Solid waste composting process was set once in a week which composting
period was seven days. The calculation of green house emission was referred to IPCC guidelines. The result
of calculation was Surabaya University could contribute to reduce green house gas emission (CH4) about
40,5 kg CH4.
