Abstract

Kota Surabaya sebagai ibu kota Propinsi Jawa Timur, mengalami persoalan pencemaran udara yang berasal dari aktivitas kendaraan bermotor. Berdasarkan data Dinas Pendapatan dan Pengelolaan Keuangan Kota Surabaya Tahun 2015, jumlah kendaraan bermotor di Kota Surabaya sebanyak 3.080.672 buah atau naik sebesar 14,8% dari tahun 2014 yaitu sebanyak 2.624.009 buah. Pertambahan kendaraan bermotor akan memberikan kontribusi meningkatnya pencemaran udara. Gas Karbon Monoksida (CO) merupakan salah satu indikator pencemaran udara. Penelitian ini menggunakan Model Aermod dengan tipe Line Area, untuk mengetahui tingkat pencemar dan dispersi gas CO di Jalan Dr. Ir. H. Soekarno. Tujuan penelitian ini adalah menentukan konsentrasi dan dispersi gas CO serta merekomendasikan strategi pengendalian pencemar gas CO yang dapat diterapkan. Metode penelitian ini dengan melakukan pengambilan sampel gas CO dan traffic cuonting. Pengolahan data berupa pemodelan pencemar gas CO yang didapatkan menggunakan Model Aermod, selanjutnya dilakukan validasi dengan konsentrasi pengukuran langsung di lapangan. Hasil penelitian mununjukan titik yang mengalami pencemaran gas CO tertinggi terdapat pada titik MERR-Klampis yaitu sebesar 58670,8 ug/m3, dengan radius dispersi sejauh 100 meter ke arah barat laut. Sedangkan konsentrasi gas CO terendah, berada pada titik MERR-Mulyorejo yaitu sebesar 12131,1 ug/m3, dengan radius dispersi sejauh 150 meter ke arah barat laut. Strategi pengendalian berupa penggunaan motor listrik dapat menurunkan beban emisi sebesar 276.825,8 g/km.jam. ============================================================ Surabaya, as a capital of East Java, encounters high air pollution due to vehicle activities. Based on the data from Revenue and Financial Management Agency in 2015, the number of vehicles in Surabaya is accounted 3 million that had increased 14.8% since 2014, accounted for 2.6 million. As they use fossil fuel, their activities contribute to the increase of air pollution with Carbon Monoxide (CO) as one of the major indicators. This research proposes Aermod model with Line Area type to identify CO level in area Dr. Ir. H Soekarno Street. The aim of this research is to identify the concentration and dispersion of CO; while the rest of this report is to recommend the strategy of CO management. The sample of CO gas and traffic counting is required for modelling air contaminant of CO gas which is taken by the model. To verify the model, measurement of CO gas concentration was taken in four sampling areas. The result shows that the highest density polluted location is MERR-Klampis, accounted 58,670.8 ug/m3, with dispersion radius 100 m to the northwest. On the other hand, the lowest polluted location is pointed out in MERR-Mulyorejo, accounted 12,131.1 ug/m3, in dispersion radius 150 m to the northwest. To sum up, it is suggested that the use of electric vehicle will reduce the amount of CO gas emission by 267,825.8 g/km.hour.
