ANALYSIS OF CARBONMONICIDE (CO) AIR QUALITY IN DKI JAKARTA DUE TO LARGE-SCALE SOCIAL RESTRICTIONS (PSBB) POLICIES FIRST VOLUME USING CLOUD- BASED COMPUTING ON GOOGLE EARTH ENGINE

Abstract

VThe corona virus first appeared in Wuhan, China and spread to Indonesia in 2020, causing the Indonesian government to implement Large-Scale Social Restrictions (PSBB) in several cities, one of which is DKI Jakarta. The government is implementing Large-Scale Social Restrictions (PSBB) which aims to stop the spread of the corona virus. During the Large-Scale Social Restrictions (PSBB) period, all community activities were mostly carried out at home, many public facilities were closed. With the implementation of the Large-Scale Social Restrictions (PSBB) policy which limits community activities in DKI Jakarta, it turns out it also has an impact on the concentration of carbon monoxide (CO) gas emissions in the air . This research uses a statistical analysis method for CO gas emissions from Sentinel-5P imagery which is extracted using cloud-based computing on Google Earth Engine. V isualization of the spatial distribution of CO gas emission content was carried out by interpolating CO data extracted using the kriging interpolation method. The results of the research show that in the first volume of the PSBB on April 10 - June 4 2020 , an unstable CO concentration pattern was seen and the average CO was obtained, namely, 0.03187 mol/m 2 . In the period a year after the first volume of PSBB 10 A April-4 June 2021, there was an increase in CO concentration by 10% to 0.0352 mol/m 2 , so this shows that the implementation of the first volume of PSBB in DKI Jakarta affected the concentration of carbon monoxide (CO) in the air
