Abstract

The study investigates the influence of operating parameters such as initial pH and distance between electrode on COD and color removal from a laboratory scale batch electrocoagulation reactor using aluminum plate (Al) with a broad cross section of 80x80 mm2 and 2 mm thick as the electrode. Synthetic wastewater Direc Red 12 B® and Direc Black Ex® is used in the study with a volume of 800 mL. The variations of experiments are distance between electrodes (2 cm, 3 cm and 4 cm) and the initial pH (4, 5, 6,7). The samples are taken every 5 minutes for 60 minutes operating time. The results of the study indicate that electrocoagulation optimal condition occurs at electrode distance 2 cm and initial pH 5 with the color removal efficiency 94.5% of the Direc Red 12 B® and 98.3% of Black Direc Ex®, COD removal 91.25% of Direc Red 12 B® and 84.92% of Direc Black Ex®.

Abstract

Higher education institutions can play a role in reducing greenhouse gas emissions through solid waste management. One of the solid waste sources in the campus is a canteen. Surabaya University (Ubaya) is one of the higher education institutions in Surabaya has two canteens that generate waste everyday. In the canteen waste is separated into food waste, food cardboards and plastic bottles. Food waste and food cardboards has not processed yet. A research related to the potential utilization of canteen waste need to be  conducted. The aims of the research are  determining the amount of organic waste generation in Ubaya canteen and calculating the greenhouse gas that can be derived if organic waste is processed into biogas. The scope of calculation was CH4 generation. The research is conducted in the Keluwih Canteen.  The estimation of canteen waste is taken for ten days. The surveys conducted during November 2017. The calculation of green house emission from solid waste was referred to Intergovernmental Panel on Climate Change (IPCC)  2006 guidelines.  The results of the research indicated that the average quantity of food waste is 6,3 kgs per day, 5  kgs per day of food cardboards and  Surabaya University can contribute to reduce green house gas emission (CH4) about 0,85 kg CH4 per day.

Abstract

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.
