Monitoring dan Analisis Kualitas Udara di Beberapa Wilayah Kota Medan yang Terintegrasi Berbasis IoT

Abstract

The background of this research is the importance of monitoring air quality in the industrial and non-industrial areas, especially in Medan, Indonesia. The growth of the industrial sector and the increased use of transportation can raise air pollution caused by the hazardous gas emission such as NO2 and CO, as well as microscopic particles like PM2.5 which have significant impact on human health. They can expecially cause respiratory diseases, heart problems, and even premature death. Ropid technological development in the Internet of Things (IoT) can detect air quality and send the result of sensor reading through the internet without cable to Android devices or Pex. The objective of this research is to design an air quality monitoring device connected to hazardous gasses, NO2 and CO, using Mics-6814 sensor, and to measure the content of PM2.5 microscopic particles using an loT based-integrated PMS5003 sensor accurately and in real- time, analyzing the result of air quality monitoring in the research location. The research methodology involves measuring air quality parameters such as PM2.5, CO, NO2, temperature, and humidity using an IoT basedintegrated designing device. The research location consists of three points: the industrial vicinity and the KIM (Medan Industrial Area) residence in Mabar, Tanjung Morawa industrial area, and the campus of Universitas Sumatera Utara. Data in figures will be tabulated from the research result within 7 hours in three days, based on the designated time. The results of the research show that the designed air quality monitoring system can measure temperature, humidity, and the content of PM2.5. NO2, CO accurately and in real-time. The data collected from various research locations show different trends. Overall, the air quality in the research location is the category of healthy; it has no impact on human, animal, and plant health according to the Decree of the Minister of Environment and Forestry of the Republic of Indonesia. It is recommended that the next researchers choose components that are more sensitive in detecting air quality and consider environmental conditions that can decrease any value deviations from the sensor.
