In Indonesian regulations, the emission standard for mobile sources is called the “Motor Vehicle Exhaust Emission Threshold.” This threshold is determined differently for new types of vehicles (which will be and are being produced) and old types (which have been circulating in the market). The emission threshold for motorized vehicle exhaust is determined by the Ministry of Environment and Forestry by taking into account the dominant and critical parameters, the quality of fuel and raw materials, as well as existing technology to ensure compliance with the obligation to control air pollution from mobile sources, the AAS Laboratory can conduct vehicle emission tests with the following parameters:

1. Opacity
2. Carbon monoxide
3. Hydrocarbons
