Abstract

Nickel ore processing plant in Indonesia is currently done by pyrometalurgy. Processing in this way requires an expensive operating costs and the waste produced can have a negative impact on the environment and so we need an alternative technology that is more effective and efficient as well as environmentally friendly. One alternative technology of low-grade nickel ore processing is the bioleaching process. Bioleaching process is a process of dissolution or release of metal or retrieval (extraction) metals from minerals into a soluble form with the aid of microorganisms.Thisstudygenerallyaimstoseparatethenickelfromlow-gradenikelore (nickeloxide) in ionic form withbioleachingprocess,andspecificallyaimstodeterminethe effectofbioleachingtime(15,30,and60days), ), theratioofmasstovolumeofnickeloresolvent (0,1 g/150 mL; 0,3 g/150 mL; 0,5 g/150 mL) andtype ofmicrooganism used (Aspergillusniger and Penicillium chrysogenum) in bioleaching process based on the concentration and yield value of the metal ion (Ni) from the extraction and knows the effect of microorganisms on the selectivity of Ni metal extracted in bioleaching process from nickel oxide. Theparameterusedarebioleaching temperature (37˚C),volume ofmicroorganisms(20% ofthe totalvolume of work),andtheparticle sizeoftheoforenickel30/40mesh. From the results of this research, highest achievement of extracted nickel ion at the time of bioleaching for 60 days with Penicillium chrysogenum with the highest extractable nickel ion concentration 4,26 ppm by the ratio of raw material to solvent 0,3g/150 mL and  for the highest  % yield (mass nickel extracted raffinate of the mass of the ore is extracted) is 12,78% (gram/gram) by the ratio of raw material to solvent of 0.3 g / 150 mL.

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.
