Jakarta, CNBC Indonesia – The Coordinating Ministry for Maritime Affairs and Investment (Kemenko Marves) revealed that the problem of air pollution in Jakarta would not be solved if only by retiring the coal-fired Steam Power Plant (PLTU). Where indeed the PLTU is one that is accused of being the main cause of dirty air in Jakarta.
Deputy Coordinator for Transportation and Infrastructure of the Coordinating Ministry for Maritime Affairs and Investment, Rachmat Kaimuddin said that air pollution in Jakarta is a complex condition. So, just retiring a coal-fired power plant is not enough to make the air in Jakarta clean.
“In principle, in these studies, these emissions come from various sources, so there are a lot of these sectors, there are a lot of them, and of course we also pay attention to the sampling method. So we can’t point out that if the PLTU closes, the air will be clean,” he explained to CNBC Indonesia in the program Energy Corner, Tuesday (22/8/2023).
Apart from that, he said that other sources that also contribute to dirty air in DKI Jakarta are from the transportation sector and the industrial sector. He said that based on a study conducted by Vital Statistics DKI Jakarta, the biggest contributors to air pollution that is currently haunting Jakarta are from the transportation, industry and power generation sectors.
“But what I use for example is from DKI, there are 9 data points for emission sources, the big three parameters, the first is transportation, the second is industry, and the third is power generation,” said Rachmat.
As for more details, Rachmat said that the transportation sector is the sector that contributes the most carbon emissions in Jakarta. Apart from that, there is also a type of pollutant that is considered the most dangerous if inhaled which is also contained in pollution produced from the transportation sector, namely PM 2.5.
“From the Jakarta Vital Statistics, of the 5 pollutants there is SO2, NOX, CO, PM 10, and PM 2.5. This is the most dangerous particle PM 2.3 because it is very small and can enter the lungs. The biggest one is 4 of the 5 pollutants in this study came out of the largest transportation sector which is PM 2.5 67%, then industry 26.8%, power plant 5.7%. So 2/3 comes from transportation,” he added.
He emphasized that there are as many as 20 million more motorized vehicles in Jakarta. This is not counting the vehicles coming in and out of Jakarta as well as the buses and trucks which are also contributors to pollution in the capital city.
“There is also a PLTU, there are thousands of industries. These are all mutual contributions. The main solution is how to reduce this combustion. How do we limit emissions if combustion occurs and how to protect the public from exposure to pollution,” he stated.
Quoting the presentation of the Minister of Environment and Forestry (LHK) Siti Nurbaya, regarding improving Jabodetabek air quality, which was delivered at a Limited Cabinet Meeting at the State Palace, Jakarta, yesterday Monday (14/8/2023), the transportation sector is the largest user of fuel in Jakarta.
The data shows that the transportation sector contributes 44% of fuel use in Jakarta, followed by the energy industry 31%, then industrial manufacturing 10%, residential sector 14%, and commercial 1%.
In terms of the largest emitters of carbon monoxide (CO), it was stated that the transportation sector contributed 96.36% or 28,317 tons per year, followed by power plants 1.76% 5,252 tons per year and industry 1.25% reaching 3,738 tons per year.
Motorcycles produce the highest pollution load per passenger compared to gasoline private cars, diesel private cars, passenger cars and buses. With a population reaching 78% of the total motorized vehicles in DKI Jakarta of 24.5 million vehicles, with a growth of 1,046,837 motorbikes per year.
However, from a Sulfur Dioxide (SO2) emission perspective, the manufacturing industry sector is the main contributor to SO2 emissions, amounting to 2,631 tons per year or 61.9%. Meanwhile, the second largest SO2 emitter is occupied by the energy industry, namely 1,071 tons per year or 25.17%. Meanwhile, motorized vehicles account for only 11% of 493 tons per year.
