The study seeks to estimate of the exhaust emission and to know the concentration of emission to several areas around. This study focuses on the Strait of Malacca area because it is one of the world's most congested straits used for international shipping where located on the border among three countries of Indonesia, Malaysia and Singapore. Exhaust emissions from ships has been contributing to the health problems and environmental damage. Global warming and air pollution have become one of the important issues to the entire world community. Results from the AIS system are: decoded MMSI, navigation status, Rate of Turn (ROT), ship speed, ship position (Longitude and Latitude), Course over Ground (COG), True Heading (HDG), Time Stamp, RAIM flag and Radio status. Lastly, binary grouping according to ITU Recommendation M.1371 and binary grouping conversion with MSB reading to decimal are done. Secondly, decimal data is converted to binary and mirrors binary data results. Firstly, AIS data with char data type is converted to decimal. The method of decoding from AIS data onto ship data consists of 3 stages. The system visualizes real-time coordinates of ships (longitude and latitude) to google maps. The system consists of hardware that functions as AIS data receiver and AIS decode software developed with LabVIEW programming language. The AIS system is automated tracking system that was used in ship industry. The AIS (Automatic Identification System) is used for monitoring ship traffic in the Singapore Strait.
