JAKARTA A total of 155 operational vehicles belonging to the Central Jakarta City Government were declared not to have passed the emission test. This finding was conveyed by the Central Jakarta Environment Agency (Sudin LH) after testing hundreds of official vehicles.

Head of the Central Jakarta LH Sub-dept., Slamet Riyadi, said that the total vehicle tested for emissions reached 419 units. Of these, 264 vehicles were declared to have passed, while 155 others failed to meet the standard for exhaust emission.

Most vehicles that do not pass belong to urban villages and sub-districts in the Central Jakarta area. We ask that these vehicles immediately undergo periodic service and use fuel in accordance with manufacturer recommendations," Slamet said when confirmed, Wednesday (30/4).

The tests were carried out in five different locations and included two-wheeled and four-wheeled vehicles. Slamet explained that a number of factors caused vehicles not to pass emission tests, including carbon monoxide (CO) and hydrocarbon (HC) levels that exceeded the threshold.

Some of the main causes include faulty combustion systems, unbalanced air and fuel mixtures, damage to oxygen sensors, and damage to catalyst components. In addition, improper use of fuel also affects emission test results," he explained.

Furthermore, Slamet added that the age of the vehicle plays a role in the inclusion of emission tests. This mainly applies to operational vehicles that are used every day and is at risk of experiencing a decrease in engine performance.

He emphasized that vehicles that do not pass the emission test have the potential to become a source of air pollution. High CO and HC content can pollute the environment and have a negative impact on public health.

"In addition to being harmful to the environment and health, exhaust gases that exceed the threshold can also damage the combustion system and the vehicle's own engine components," he said.
