Indonesia Conference Directory

Indonesia has a number of small businesses totaling 757,090 units in 2017. One of these small business units is the household scale industry. The number of tofu industries in Indonesia is very much, seen from the figures of tofu consumption in Indonesia in 2012 which reached 3,010,742.3 tons. However, most industrial sectors know that household scale in Surabaya does not yet have tofu wastewater treatment units. This is due to financial constraints and the land owned so that the liquid waste produced is directly discharged into the river without any processing. This can cause a decrease in environmental power due to the high content of organic pollutants in tofu liquid waste. Through the Karsa Cipta Student Creativity Program (PKM-KC) a "ABACTOR - CELLS" tool has been designed as a household scale wastewater treatment unit. This tool adopts the working principle of the Anaerobic Baffled Reactor (ABR) and Microbial Fuel Cells (MFCs) which are combined into one processing unit. MFCs are wastewater treatment units that utilize bacteria to convert organic pollutants into electrical energy. MFCs are combined with ABR which is a practical processing unit and does not require high operational costs so it is suitable for application to the tofu industry sector. ABACTOR - CELLS can be an innovation as an electricity generating unit by utilizing bacteria to process pollutants in wastewater. This ABACTOR-CELLS requires a processing time of 12 hours. With this process, this unit is capable of producing electricity of 0.336 Watts. In addition, this unit is able to reduce the Chemical Oxygen Demand (COD) content from 1563.86 mg / L to 297,474 mg / L with a percentage of 81% which is equivalent to the weight of COD of 0.055 kg. While the percentage of removal for Biochemical Oxygen Demand (BOD) content is 84.4% with BOD inlet of 953.74 mg / L and BOD outlets of 148.74 mg / L. The decrease in the value of COD and BOD shows that besides producing electricity, ABACTOR-CELLS can also play a role in reducing environmental pollution, especially in water bodies.
