Monitoring System Transportation using Air Quality Based on IoT in Semarang

摘要

Air Pollution Standard Index in a city is Semarang City with PM 10 7 and Air Quality Index (AQI) 67. Air pollution monitoring with portable systems is rarely found to obtain direct data. This research aims to make a portable device to determine air quality in the city of Semarang to facilitate control. Air quality testing is integrated with Internet of Things technology to adjust the conditions of the 4.0 industrial revolution so that air conditions are immediately known in real-time. The prototype method is a series of systems that determine the air quality and quantity of components. The prototypes are the MQ-6 type sensor for CO2 and smoke identification, MQ-7 (CO, LPG, and CH4), MQ135 (Butane and Air Quality), and DHT-11 (Humidity and Temperature). A gas sensor equipped with an Arduino microcontroller was tried in a location and tested to produce the average pollution conditions in a traffic activity for CO and CO2 with levels of 8.72 ppm and 6.63 ppm, respectively. The result is that CO and CO2 are still below the threshold, while NH3 and C4H10 are still safely below the threshold. This value shows that the pollutants that affect, especially CO2 and CO, generated from the land transportation system during busy working hours at 8-9 a.m and 4-7 p.m that the result of fuel combustion during transportation.
