What is Air Pollution?
Air pollution is the result of the mixing of pollutant substances in the atmosphere because they exceed a reasonable amount. Some of the pollutants contained in the air include Sulfur Oxide (SOx), Carbon Monoxide (CO), Carbon Dioxide (CO2), Nitrogen Oxide (NOx), and Hydrocarbons.
Sources of air pollution can come from human activities and natural events. Human activities such as infrastructure development, industry, transportation, and others contribute to air pollution.
Air quality has important significance for various aspects, but it is not uncommon for humans to pay less attention and realize its impact.
Pollution Level in Jakarta
Public debate and media coverage in recent times has focused on the deteriorating air quality in Jakarta due to pollution. The effects of air pollution can increase the risk of city residents suffering from Acute Respiratory Infection (ARI).
Referring to the IQAir website, Wednesday (23/8/2023) At 09.00, Jakarta’s AIR Quality Index (AQI) reached 161. Jakarta is also the city with the fourth highest pollution level in the world, after the city of Baghdad, Iraq.
The concentration of PM2.5 particulates in Jakarta on Wednesday (23/8) was 15.1 times above the annual air quality guideline value of the World Health Organization (WHO).
Referring to the information listed on the official website of the Meteorology, Climatology and Geophysics Agency (BMKG), PM2.5 refers to airborne particles with a diameter of 2.5 micrometers or smaller. Particles of this type PM2.5, such as dust, soot, dirt, smoke, and liquid droplets, can only be detected through the use of an electron microscope.
Plt. Deputy for Climatology at the Meteorology, Climatology and Geophysics Agency (BMKG) Ardhasena Sopaheluwakan also revealed several sources of air pollution in Jakarta and its surroundings.
“The poor air quality in an area is caused by many factors, such as motorized vehicles to the energy sector, such as a Steam Power Plant (PLTU),” he said in his statement to CNNIndonesia.com, Monday (21/8).
“Emissions issued by the PLTU are indeed one of the factors causing poor air quality, but they are not the only factor,” he continued.
Ardashena explained that the deteriorating air quality in an area is the result of the accumulation of various human activities, including the use of motorized vehicles and the energy sector such as Steam Power Plants (PLTU).
According to Ardashena, based on research findings conducted by the DKI Jakarta Province Environment Agency (DLH) in 2020, the power generation sector, including PLTU, only has an impact of around 5.7 percent (ranked third) on deteriorating air quality in Jakarta.
“The source of transportation emissions is still the biggest sector contributing to poor air quality in Jakarta,” he said.
The following are sources of pollution according to DLH DKI:
- Transportation (67.04 percent)
- Industry (26.8 percent)
- Power plants (5.7 percent)
- Housing (0.42 percent)
- Commercial (0.02 percent)
