The industrial sector is said to be the culprit of emissions that cause air pollution in the Jabodetabek area. Cement is one of the industries blamed for this, amidst the high demand for infrastructure development in the capital city and its supporting areas.
However, based on data from the Ministry of Environment and Forestry, the sector that contributes to air pollution in Jakarta is actually transportation at 44% (from fuel use), followed by the energy sector at 31%, the housing sector at 14%. Furthermore, only the manufacturing sector appears with a portion of 10%, and the commercial sector by 1%.
In response, Chairman of the Indonesian Cement Association (ASI) Lilik Unggul Raharjo said that the cement industry is one of the industries that is heavily regulated with policies to tackle air pollution. According to him, the cement industry is an industry in the manufacturing sector designed with a closed combustion system and equipped with a controlled air emission system.
The air emission concentration of the cement industry has been regulated in the Minister of Environment and Forestry Regulation Number 19 of 2017 concerning Emission Quality Standards for Cement Industry Businesses and/or Activities. Cement companies also generally install filters that have a particle filtration efficiency of up to 99% according to Environmental Protection Agency (EPA) standards in the United States (US).
‘The initial design of cement industry chimneys has been equipped with an air pollution control system for particulate emissions, sulfur dioxide or SO2, and nitrogen oxides or NOx, namely an Electrostatic Precipitator (EP) with an efficiency of 99%. To improve the performance of the air pollution control system, several cement companies have installed bag filters, which have a particle filtration efficiency above 99%,’ he told CNBC Indonesia, Thursday (21/9/2023).
In addition, he continued, the cement industry is required to install Continuous Emission Monitoring (CEM) on the main chimney to monitor emissions continuously. The Ministry of Environment and Forestry also requires the cement industry to install the Continuous Industrial Emission Monitoring Information System (SISPEK), a system that receives and manages emission monitoring data from the CEM.
‘The information system is directly connected to the server and monitored by KLHK, so that supervision by the government can be carried out at any time,’ Lilik explained. He also added that in business terms, emissions coming out through the chimney are avoided by the industry because it is a loss from the process side with heat loss and product loss.
‘The cement industry is an industry that is open and cooperative to input and direction from regulators, such as the Ministry of Environment and Forestry and the Ministry of Industry, both through direct and indirect supervision,’ he concluded.
The cement industry’s innovations through its various products also make its products more environmentally friendly and low in carbon emissions. Some of the latest innovations are also the best solutions that can dry in a few hours.
Real Contribution to Infrastructure
Furthermore, Lilik explained, cement plants contribute to the completion of infrastructure projects in the DKI Jakarta Region, including road projects (including the busway), bridges or flyovers, sports stadiums, Integrated Highways (LRT) and Integrated Highways (MRT), high-speed railways, social facilities, and public facilities such as schools, hospitals, sidewalks, and green open spaces.
‘(Contributions are made) in the form of cement supply, concrete, as well as construction and integrated solutions,’ he said.
For the record, DKI Jakarta is currently developing public transport projects, namely LRT and MRT. The national strategic project of Jakarta LRT Phase 1 B Velodrome-Manggarai trajectory starts in August 2023, while the Jakarta MRT construction project enters phase 2 which stretches along about 11.8 kilometres from the HI Roundabout area to West Ancol.
Then repairing 14 corridors of the TransJakarta bus line, including HI Roundabout, Sarinah Stop towards HI, Juanda Stop towards Senen, Juanda Stop towards Harmony, City Hall Stop towards Horse Statue, and Jln. Raya Kramat Kwitang towards Senen. Then Jln. Kyai Tapa towards Roxy, New Bridge Stop, Jln. MT Haryono towards Semanggi, Jln. Gatot Subroto towards Semanggi, Jln. Kemayoran Gempol, and Jln. Utan Panjang Timur.
There is also the Multipurpose Pedestrian Bridge project in Dukuh Atas, Sudirman, Jakarta, which was completed recently. JPM Dukuh Atas is a connecting bridge integrated with five modes of public transport, namely Jabodebek LRT, MRT, KAI Commuter Line, TransJakarta, and Airport Train Station.
In addition to transport, the DKI Jakarta region is also building the Jakarta Outer Ring Road (JORR) Elevated Toll Road Cikunir-Ulujami Section. This lane is part of the Jabodetabek toll road which is above the Existing Jakarta Outer Ring Road (JORR) Toll Road.
