Emission analysis due to port activity at Tanjung Perak Port Surabaya using system dynamics methods

Abstract

Tanjung Perak Port is the second largest port in Indonesia. Tanjung Perak Port has a capacity of 24.1 million TEUs. There was an increase in container flows in 2017 of 4.9 million TEUs and in 2018 of 5.3 million TEUs, making the Tanjung Perak port excess container capacity. High port activity and increased loading and unloading traffic have resulted in increased air pollution every year. Where air pollution is caused by exhaust emissions produced by ships, loading and unloading equipment, and port container truck traffic. The increased exhaust emissions will have an impact on the air quality around the area. The resulting emissions include SOx, NOx, CO, CO2. The exhaust gas emission which exceeds the reasonable threshold according to the determined standards can cause ARI. So this study aims to determine the total value of exhaust gas emissions due to port activities. In calculating exhaust emissions using the US EPA method. This research was assisted by using the Powersim Studio software that uses the system dynamics method. The results obtained from exhaust gas emissions PM 10 792,623 kg / year, PM 2.5 emissions 39.15 kg / year, emissions NO 46101,316 kg / year, SO emissions 0.063 kg / year, CO emissions 18042,655 kg / year, CO2 emissions 406 324,108 kg / year, emissions HC 2595,823 kg / year, SO2 emissions 89.2 kg / year, NMHC emissions + NO 1178.33 kg / year.
