Analysis of the impact of vehicle density on carbon monoxide concentration in the vicinity of the Tello Diesel Power Plant in Makassar, Indonesia

The mobilization of individuals from one location to another using transportation has become increasingly essential for human life. However, the transportation sector is the largest contributor to emissions, primarily due to the rising use of motor vehicles each year. This study aims to assess air quality about vehicle density by utilizing a gas sampling device known as a midget impinger to collect carbon monoxide (CO) samples. The air samples were subsequently analyzed in the laboratory using a non-dispersive infrared CO detector. Air sampling was conducted concurrently with data collection on the number of vehicles at three designated sampling locations: Urip Sumoharjo Street west of the Diesel Power Plant (A), Leimena Street to the north (B), and Leimena Street to the east (C), with a one-hour interval for data collection. The findings indicate that the concentration of CO gas at the three research locations surrounding the Tello Diesel Power Plant in Makassar remains within safe limits, according to the National Ambient Air Quality Standards. The highest average vehicle density was observed on Urip Sumoharjo Street, while the lowest average vehicle count was noted on the eastern section of Leimena Street near the Tello Diesel Power Plant. Furthermore, the results reveal a significant relationship between vehicle density and CO concentration in the vicinity of the Tello Power Plant, with an average coefficient of determination for CO of 90.3%.
