This study aims to map the concentration of carbon monoxide (CO) in Medan city and to estimate the potential reduction in carbon monoxide in some streets of Medan by applying mass transit based on simulation. This research was conducted by sampling CO in the 12 (twelve) points in Medan by grab sampling. CO concentration was analyzed using NDIR methods by CO Monitor tools. The results showed the concentration of CO in Medan between 1145.2 mg/m3 - 27484,7 mg/m3. This condition is still below the national ambient air quality standard of Government Regulation No. 41, 1999 (30,000 mg/m3). Based on the concentration isophlet map that points that have the highest concentration located in the surrounding roadside such as at Jl. SM Raja. To reduction the CO concentration in the ambient air around the roadside is necessary to plan programs and policies related to transportation. If the scenarios or simulation with application of the concept of mass transportation such as BRT CNG and BRT Diesel in some streets of Medan then will be able to reduce CO emissions of about 25.02% to 29.44%.Keywords: vehicle emissions, carbon monoxide, map isophlet, mass transitABSTRAKPenelitian ini bertujuan untuk memetakan konsentrasi gas karbon monoksida (CO) di Kota Medan dan melakukan estimasi potensi penurunan karbon monoksida di beberapa ruas jalan Kota Medan dengan menerapkan transportasi massal berbasis simulasi. Penelitian ini dilakukan dengan pengambilan sampel CO di 12 (dua belas) titik di Kota Medan secara grab sampling. Konsentrasi CO dianalisis menggunakan metode NDIR dengan alat sampling yaitu CO Monitor. Hasil penelitian menunjukkan konsentrasi CO di Kota Medan antara 1145,2 mg/m3 27484,7mg/m3. Kondisi ini masih dibawah baku mutu udara ambien nasional Peraturan Pemerintah No. 41 tahun 1999 (30.000 mg/m3). Berdasarkan peta isophlet konsentrasi tersebut bahwa titik-titik yang mempunyai konsentrasi tertinggi berlokasi di sekitar jalan salah satunya seperti di Jl. SM Raja. Untuk menurunkan konsentrasi CO di udara ambien di sekitar jalan perlu dilakukan perencanaan program dan kebijakan terkait transportasi. Apabila dilakukan skenario atau simulasi penerapan konsep transportasi massal berupa BRT CNG dan BRT Diesel di beberapa ruas jalan Kota Medan akan mampu mengurangi beban emisi CO sekitar 25,02% sampai dengan 29,44%.Kata kunci : emisi kendaraan, karbon monoksida, peta isophlet, transportasi massal

Ambient Air Quality Standard

According to the information of air quality which published by the urban air quality real-time publishing platform, the concentration characteristics of PM10 and PM2.5 were studied in Kunming (KM), Changsha (CS), Hangzhou (HZ), Shanghai (SH), Harbin (HEB), Beijing (BJ), Wuhan (WH) and Guangzhou (GZ). The results show that the concentrations of PM10 and PM2.5 exceeded the Ambient Air Quality Standard (GB3095-2012) in varying degrees in March, 2013. The concentrations of PM10 in Wuhan is the highest, reached 164μg/m3, exceeded the standard by 9.3%; the concentrations of PM2.5 is much higher in Wuhan, Changsha and Beijing, the average concentrations were 96μg/m3, 103μg/m3 and 110μg/m3, exceeded the standard by 28.0%, 37.3% and 46.7% respectively. The correlation of PM10 with PM2.5 in most of these cities was good in March. The correlation analysis of pollutant with meteorological factor in Hangzhou, Shanghai, Beijing and Guangzhou was also studied, the results show that the concentrations of PM10 and PM2.5 are weakly positive correlation with temperature in the four cities, negative correlation with relative humidity without Beijing, and negative correlation with wind speed.

The purpose of this research are to analysis air quality and dust impact to people that came from factory activities at residential area around factory location of PT. Semen Padang. Measuring of air quality conducted in 3 residential area that are Komplek RW 1, RT 3 Batu Gadang district, Perumnas Indarung RW. VII, and housing of UNAND Blok D Gadut, using Personal Dust Sampler. The result is respirable dust concentration at housing complex RW. 1 RT. 3 Batu Gadang district that is 0,33 mg/m, the Perumnas Indarung RW.VII that is 0,55 mg/m along with housing of UNAND Blok D Gadut that is 0,44 mg/m. Concentration of dust respirable at all are still below ambient air quality standard that exist on PP RI No. 41 Tahun 1999, 3 mg/m. Based on quesioner and puskesmas data proximate with use univariat analysis, negative impact who feels people are impact of health is eyes irritation disease and impact of environment especially community-owned material. Keywords: air quality, negative impact, residential area, respirable dust, PT. Semen Padang ABSTRAKPenelitian ini bermaksud untuk menganalisis kualitas udara dan dampak negatif yang dirasakan masyarakat dari debu yang berasal dari aktivitas pabrik di kawasan perumahan sekitar lokasi pabrik PT. Semen Padang. Pengukuran kualitas udara dilakukan di 3 kawasan perumahan yaitu komplek perumahan RW. 1 RT. 3 Kelurahan Batu Gadang, Perumnas Indarung RW. VII, dan Perumahan UNAND Blok D Gadut dengan menggunakan alat Personal Dust Sampler. Diperoleh hasil konsentrasi debu respirable pada komplek perumahan RT.3 RW.1 Kelurahan Batu Gadang sebesar 0,33 mg/m, pada Perumnas Indarung RW.VII sebesar 0,55 mg/m serta pada Perumahan UNAND Blok D Gadut sebesar 0,44 mg/m. Konsentrasi debu respirable pada ketiga lokasi masih berada di bawah ambang batas baku mutu udara di lingkungan, 3 mg/m. Berdasarkan kuesioner dan data puskesmas terdekat dengan menggunakan analisis univariat, dampak negatif yang dirasakan masyarakat adalah dampak terhadap kesehatan berupa penyakit iritasi mata dan dampak terhadap lingkungan khususnya pada kondisi material yang dimiliki masyarakat.Kata kunci: kualitas udara, dampak negatif, kawasan perumahan, debu respirable, PT.
