Measurement and analysis of air quality impacts caused by CO and NO2 on Margonda Raya street Depok

Abstract

Based on data from the Central Statistics Agency (BPS) in 2019, the population of the City of Depok has now jumped to 2,254,513 people. Analysis of air quality is important for the people of Depok. The biggest ambient air parameters are Nitrogen Dioxide (NO2) and Carbon Monoxide (CO). Land transportation activities are among the biggest causes of decreasing air quality in the city of Depok. One type of land transportation is motor vehicles. A high growth rate of motor vehicles can cause a serious impact on the environment. Traffic jams and noise can cause air pollution. This research was conducted around Margonda Raya Street. In this research, the components used are Arduino Mega 2560 Microcontroller, SHT11 Temperature and Humidity Sensor, MQ-7 CO Sensor, MQ-135 NO2 Sensor, Wi-Fi Module ESP8266, Wind Direction and Wind Speed JL-FS2 Sensor. Data from the designed tool will then be sent to the cloud server which will then be collected in a web-based application. The results will be analyzed to determine for fluctuations in CO and NO2 gas concentrations and the impact of CO and NO2 on air quality around Margonda Raya Street Depok. The MQ-7 and MQ-135 Sensor test results show a very strong correlation value with the value R2 = 0.9906 for MQ-7 and R2 = 0.9988 for MQ-135. The results of the test show that in the Region has the highest CO value of 202.67 around 3:00 to 4:00 p.m. and the highest NO2 value of 227.34 around 2:00 p.m., the data values of CO and NO2 are still in the medium category, this is related to the decline in community activities on weekends.
