Abstract

CNC machine coolant waste is one type of B3 (Bahan Berbahaya dan Beracun / toxic and hazardous waste) liquid waste from industrial activities that must be treated with certain quality standards to reduce the impact of water pollution. Waste disposal regulations for distribution to water bodies require that the condition of the physical parameters of processed waste meet the threshold value as a requirement for quality standards including the level of turbidity and total dissolved solids. Under the Decree of the Minister of Health No. 907 of 2002, the turbidity level of wastewater that meets the requirements for clean water is a maximum of 5 NTU, while the total dissolved solids (TDS) is a maximum of 1000 mg/l, In this study, a coolant waste treatment system was developed through the use of the electrocoagulation process to treat waste by applying the Fuzzy logic method as process control. The input of the Fuzzy system is the threshold value of the turbidity parameter and TDS. The experiment of coolant wastewater treatment system using the Fuzzy logic method with an input value of 5 NTU and 1000 mg/l used as a parameter generated Fuzzy output in the form of a PWM value of 244 with a voltage of 22 V and a process contact time of 70 minutes and adjusted the turbidity of the waste from 6376 NTU to 1.13. The NTU and TDS of the initial waste that cannot be measured after going through the processing process were reduced to 143 mg/l, The efficiency of the Fuzzy output voltage through the regulation of the PWM value to the voltage drop due to the increase in the load current on the electrodes was obtained by 94% with the volume of the waste sample used as much as 1.5 liters.
