Performance Analysis Monitoring of Sugar Factory Liquid Waste IoT Based

One of the causes of water pollution is waste water from industrial activities that do not meet the standards and lack of waste water monitoring activities. In an increasingly technological era, manual monitoring activities are one of the problems faced. Sugar Plant Liquid Waste Monitoring Design Building that utilizes the development of this technology is used to conduct waste water monitoring activities that have gone through the wastewater treatment process. This monitoring uses 5 parameters of wastewater namely ammonia / hydrogen sulfide gas, pH, turbidity, temperature and dissolved oxygen levels. Ammonia / hydrogen sulfide gas parameters using TGS2602 gas sensor, pH parameters using pH sensor, turbidity parameter using turbidity sensor, temperature parameters using DS18B20 sensor, and dissolved oxygen parameters using Dissolved Oxygen (DO) sensor. Using Arduino Mega 2560 as a data processor and 433Mhz RF module as a wireless communication medium. The overall test results work well. The gas sensor is able to detect levels of ammonia / hydrogen sulfide from 0 to 30 ppm, turbidity sensors capable of measuring the turbidity level of 0-987 NTU. The pH sensor is able to measure the level of water pH 0-14 which has been calibrated with a pH buffer 9.18. The temperature sensor is able to detect temperature values with a range of -55 ° C - 125 ° C. And at a temperature of 10 ° C - 85 ° C has an accuracy value of approximately 0.5 ° C. DO sensors are able to detect DO values from 0 - 35 mg / L with an accuracy value of approximately 0.1 mg / L which has been calibrated with a 0 mg / L DO solution. RF 433Mhz can send data with a maximum range of 7 m.
