The Meteorology, Climatology and Geophysics Agency (BMKG) said Jakarta’s air quality data was classified as good on a green scale. This was revealed to be related to the condition of air pollution after the application of work from home to avoid the spread of Covid-19.

According to the Head of BMKG Climate Information and Air Quality Production Sub-Division, Siswanto, the PM10 content in Jakarta’s air shows a very low concentration in the range of 0-50 µgram / m3.

Meanwhile, according to Greenpeace Indonesia data, Jakarta’s air quality today shows moderate quality. Based on data on the AQI (Air Quality Index) website, Greenpeace Indonesia’s Energy Campaigner Bondan Andriyanu said the concentration of air pollutants in Jakarta is at the level of 14 µgram / m3.

The effect of work at home?

However, when asked whether Jakarta’s good quality of air is related to the policy of working from home, Siswanto could not confirm that. According to him, the effect can only be seen within a week.

Because, according to Siswanto, there is a possibility of a decrease in PM10 pollutants reduced due to the rainy season. Because, in the rainy season PM10 concentrations tend to decrease due to the process of washing by rain (rain washing).

In line with Siswanto, Greenpeace Indonesia’s Energy Campaigner, Bondan Andriyanu said that he could not conclude Jakarta’s air quality in the past three days.

Because, there are a number of factors that influence for example the action of burning waste which also contributes to pollutants.

“We can not say this is good or not. Then there are several factors, 21 days there was rain then the wind was pretty strong. Not to mention other sources such as those that burn rubbish,” said Bondan.

Due to the Corona lockdown, pollution from China and Italy has fallen

Previously, the European Space Agency said lockdown had a large positive effect on CO2 emissions.

ESA’s Sentinel-5P satellite shows the concentration of nitrogen dioxide in Italy produced by cars and power plants has decreased dramatically from January 1 to April 5, 2020.

Similar to Italy, according to NASA and European Space Agency monitoring, air quality in China has improved significantly since January 1, 2020.

The European Union Earth Observation Program says satellite measurements show that PM2.5 pollution levels in China in February 2020 fell by around 20 to 30 percent compared to the average for the same month in 2017, 2018 and 2019. (din / ex)
