Abstract

Textile industry is one of important industry in Asian and other country which its industry account for almost 30 percent of county's income. Besides it gives the contribution, it also affect our environment with its textile wastewater. Not only it contribute to pollution, it also affect human and aquatic life. . Many party take an initiative to reduce effect of textile wastewater. Method used are physical, biology and chemical. From three of method used, most effective method is biological method because it is environmental friendly. The treatment is approved to reduce carcinogen effect to human. Main objective of this study is to confirm the best strain that can be developed into bacteria consortia and the second objective is to study effect of physical factor of bacterial consortia production which affecting decolourisation capability of Remazol red dye. Physical factor which affecting decolourisation of Red dye by bacteria consortia. This is a critical part in this study where physical factor of pH, temperature, inoculum size is study within 96 hours in incubator shake flask with temperature 37 °C, 150 rpm. The percentage decolourisation of textile dye is analyse by using SPSS of two way factorial to study the relationship of each parameter. Before proceed with this stage, selected strain that capable of degrading dyes is developed to make a consortium. A consortium is comprised of strain B9, B3, B5 and C5. B3 is Enterobacter clocae, B5 is Bacillus arbutinovarans, B9 is Bacillus cereus dan C5 is Pseudomonas mendocina. The highest percentage of decolourisation denotes the optimum parameter for bacteria best work to degrade Remazol red. The optimum temperature that the consortia best work is 30°C while favourable pH is pH 3 while the most optimum of inoculum size is 10%. Textile wastewater has a pH range from 5 to 10. It means bacterial can work in acidic condition near to alkali condition. The temperature of textile wastewater is range between 33°C to 55°C. The increase in size of inoculum size increase in percentage decolourisation. Textile wastewater can be treated with other method like physical, biological and chemical method. Recently, the method used are oxidation process, anaerobic and aerobic treatment and flocculation or coagulation. The method is effective but other problems arise like textile dye become carcinogen after treat with aerobic treatment and yet the method is very costly.
