The capability of green open space in absorbing carbon monoxide and carbon dioxide emissions in Balai Kota Makassar

Abstract

The economic growth will increase the transportation sectors roles in supporting the achievement of development goals. But transportation activities have negatives impact, where one of the negative impact of transportation activities is the high levels of pollutants due to emissions or release of smoke from motor vehicles. This study aims to determine the capability of green open space that exists, especially in the ability of trees and shrubs in absorbing carbon monoxide and carbon dioxide emissions generated by motor vehicles operating in Balai Kota Makassar. The research is qualitative. All data required for the analysis of the research are primary data or data obtained directly in the field. Primary data in this research are data obtained by counting the number of vehicles and the area cover by vegetation canopy. In this research, zonation system is applied because each area has different green open space requirement based on the emission load generated by motor vehicles passing in the area so that the research location is divided into 4 zones. To calculate the vehicle’s emission, it applies the equation of emission strength, and to calculate the emission absorption by vegetation is use vegetations area covers. The results showed in zones 1, zone 2 and zone 3, green open space existing already can absorb 100% carbon dioxide emissions and carbon monoxide. But in zone 4, green open space existing cannot absorb 100% carbon dioxide emissions and carbon monoxide.
