Analisis Kualitas Udara dan Beban Emisi Karbon Monoksida (CO) Akibat Kendaraan Bermotor di Persimpangan Jalan Gatot Subroto dan Jalan Kapten Muslim Kota Medan

Abstract

Medan City is a city that has a high population density. According to data from the Medan City Central Statistics Agency (BPS) (2022), the population of Medan City reaches 2,460,858 people. The transportation sector plays a very large role and has the potential to pollute the air compared to other sectors. Sihombing (2017) said that large cities contribute 60-70% of motor vehicle exhaust, industrial production is around 10- 15% and the rest comes from household activities, burning rubbish, forest fires and so on. The number of vehicles in Medan City has reached 288,378 units (BPS 2022). According to Basalamah (2020), performance analysis of the intersection of Rajawali street, Merak street, Kasuari street in Sei Sekambing B Village, Medan Sunggal.The district has a busy time on Monday 16 July 2018 at 16.00-18.00 WIB with calculations every 15 minutes within 2 hours. The analysis results obtained show that this location has a degree of saturation (DS) = 1.06, which means it has caused traffic jams. Research is needed on Air Quality Analysis and Carbon Monoxide (CO) Emission Load Due to Motor Vehicles at the Intersection of Gatot Subroto street, Medan City. Based on the calculation results, the highest Carbon Monoxide (CO) emission load on Gatot Subroto was at TS-2, namely 67.20 g/hour, while the lowest emission load was at TS-16, namely 41.81 g/hour during the daytime measurement. The highest emission load on Kapten Muslim was the highest value at all sampling points, namely 120.03 g/hour during the afternoon measurement time and the lowest emission load was TS-12, namely 84.91 g/hour during the afternoon measurement time. Then, the highest emission load on Sunggal was on TS-6, namely 35.33 g/hour during the afternoon measurement, while the lowest emission load was on TS8, namely 24.15 g/hour during the morning measurement.
