Abstract
The incidence of poisoning due to carbon monoxide gas arising from drilling activities on the first floor of a building in the Kelapa Gading beauty clinic in Jakarta resulted in 17 people experiencing poisoning. In this study developing a device on the sensor used to detect CO and SO2 gas, in the air of a closed room using gas sensor MQ 135 and MQ 136. The results of testing the CO and SO2 gas gauges using samples of cigarette smoke and sulfur powder using MQ 135 and MQ 136 sensors with fuzzy rule base logic for motor speed to produce CO and SO2 gas, that obtained a value of 0.233 ppm SO2 gas safe conditions and gas input CO with the sensor obtained a value of 0.513 ppm, the condition is safe so that the output is 49.8 ppm, the condition of the fan blower does not rotate. Whereas when the reading value of 5.0 ppm is very concentrated and the CO gas input with the sensor is 13.8 ppm the condition is very concentrated producing an output of 228 ppm the very danger.
Highlights
The danger caused by explosion of sulfur dust is a major risk factor that threatens human safety, by evaluating and controlling the danger of sulfur dust generated in the wet process is very important
The results show that sulfur dust can be ignited and has a high explosive power
The results of testing sensor readings on carbon monoxide gas slides, namely from cigarette smoke or vehicle exhaust and sulfur gas powder from heating based on 16 fuzzy rules consisting of Carbon monoxide (CO) and SO2 gas input with fan blower speed output as suction or content neutralizer gas grating in a closed room
Summary
The danger caused by explosion of sulfur dust is a major risk factor that threatens human safety, by evaluating and controlling the danger of sulfur dust generated in the wet process is very important. Especially dense urban areas with high traffic density, so tens of millions of people live in countries where air quality threatens health. From the phenomenon of the effects of the danger of toxic gases carbon monoxide and sulfur for humans, in this study how to design a device that can detect. This designed tool is made using the control of the Arduino microcontroller, with gas sensor inputs MQ 135 and MQ136 that work based on the fuzzy method to provide information on safe gas exposure conditions, approaching danger, danger and very dangerous. The condition of the room when approaching danger, danger and very danger will be neutralized by a fan blower that can suck and dispose of CO and CO2 gas gases automatically so that there is no gas deposition in the room and safe for humans [7]
