Abstract

The growth of motorized vehicles in Indonesia reached 4.1% with a total number of vehicles of 136,137,451. Vehicle units operated on the highway will cause an increase in noise on the highway caused by the operation of vehicle horns. The Indonesian government has regulated horn noise quality standards through Peraturan Pemerintah Nomor 55 Tahun 2012. Indonesia has agreed to the Asean Mutual Recognation Agreement (MRA) for automotive product standards in the Asean region referring to UN ECE where for horn testing it refers to the UN ECE R28 Part II standard. From testing the horn at durations of 1, 5, 10 and 15 seconds using a battery and an idle engine, there was no significant difference in the resulting horn sound level. This research aims to ensure the source of electric current when testing the horn so that the test can run more effectively and efficiently by establishing in the operational standards the UN ECE R 28 Part II test procedure using a battery only

Abstract

Motor vehicle exhaust emissions containing carbon monoxide (CO) and hydrocarbons (HC) are a strategic issue for Indonesia, which has not yet set an age limit for motor vehicles. As a control measure, the Indonesian government itself has issued regulations on exhaust gas emission quality standards for motorized vehicles that are used by the public through Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 8 of 2023. Catalytic converter technology is the most effective system for reducing CO and HC emissions. Currently, it is from the Platinum Gold Metal (PGM) group, namely Platinum, Palladium, Rhodium which is still very expensive. This article uses a literature review research method with reference sources originating from previous research journals by comparing. This paper will discuss gas emissions, the development of converter catalytic materials and also the effectiveness of converter catalytic materials from the non-PGM metal group, namely Copper (Cu) and Brass/ Brass (CuZn) which has been proven to be able to reduce exhaust gas emissions so that it can be an alternative as a converter catitic at a more affordable price for the wider community
