The Effectivity of Roadside Green Belt in Reducing the Concentration of CO Gas Pollutant

Abstract

Polusi udara merupakan masalah serius yang meningkat dan terjadi di hampir semua negara, termasuk di negaranegara maju. Polusi udara yang meningkat umumnya disebabkan oleh aktivitas manusia, seperti transportasi. Salah satu zat polutan berbahaya yang dihasilkan oleh kendaraan bermotor ialah polutan CO (karbon monoksida). Salah satu upaya dalam mengendalikan polusi udara ialah pemanfaatan dengan ruang terbuka hijau di area pinggir jalan. Tujuan penelitian ini adalah untuk memberikan gambaran tentang pengaruh area vegetasi dan area terbuka dalam mengurangi penyebaran polutan gas CO yang dihasilkan oleh kegiatan transportasi. Penelitian ini dilakukan di jalur hijau jalan Tol Cikampek. Pengambilan sampel udara dilakukan untuk mengukur konsentrasi CO dalam jarak 0, 10, dan 30 m dari tepi jalan jalur hijau. Untuk menentukan konsentrasi CO digunakan analisis dengan metode spektofotometri. Hasil penelitian menunjukkan bahwa faktor vegetasi dan jarak dari jalur hijau secara signifikan memengaruhi distribusi konsentrasi gas CO. Area jalur hijau mengurangi distribusi polutan CO di sekitar jalan Tol Cikampek. Hasil penelitian menunjukkan bahwa plot area vegetasi secara efektif dapat mengurangi konsentrasi gas CO sebesar 8,5% dibandingkan dengan plot terbuka. Dalam penelitian ini ditemukan bahwa konsentrasi gas CO pada plot area vegetasi dalam jarak 10 dan 30 m secara berturut-turut menurun sebesar 14,5 dan 23,55%. Sementara itu, di area plot terbuka dalam jarak 10 dan 30 m konsentrasi gas CO menurun sebesar 7,17 dan 15,05%.

Air pollution dispersion modeling of runway and apron at Sam Ratulangi international airport

“…As stipulated by local government, of at least 30% should be providedby the airport as green open space in order to reduce gas emission impacts tothe city of Manado surrounding area. Green open area plots in roadside areas could effectively reduce CO concentrations by 8.5% compared to open plots [14]. In this study, there was a compelling correlation between wind and CO concentration.…”

Dispersion of Carbon Monoxide Pollutant and The Effect of Health (Case Study on Frontage Road Surabaya by Gaussian Line Source Equation Model)

“…In this study, a simulation model is needed to provide an overview of the distribution of carbon monoxide pollutants produced by motorized vehicles in the Ahmad Yani frontage so that the dangers of the gas can be anticipated and as a material for consideration in taking the next steps by policy makers regarding this matter. In addition to vehicle speed, wind speed and wind direction are also influential in this study (Gallagher & Lago, 2019;Kiesewetter et al, 2014;Izzah et al, 2019). Wind speeds are low enough to cause the carbon monoxide pollutant produced to not leave the road immediately (Izzah et al, 2019).…”

VEGETATIVE GROWTH OF CASSAVA (Manihot esculenta Crantz.) ON THE LIQUID ORGANIC FERTILIZER OF LEGUMINOSAE SPECIES AND CONCENTRATION

“…More pollution is caused by vehicles and industrial sector contributes to increase CO 2 levels in the air. Ismayati et al, (2014) in Izzah et al, (2019) stated that air pollution in Indonesia is contributed by motor vehicle exhaust gases by 60-70% and by industry by 10-15%. In 2017, the concentration of CO2 in the atmosphere was 405.6 ppm and continued to increase, followed by an increase in earth temperature (Kurnia, 2020).…”
