Abstract

Surabaya merupakan ibu kota Provinsi Jawa Timur dan termasuk dalam beberapa daftar kota besar di Indonesia. Meningkatnya aktivitas perekonomian, industri, dan lain sebagainya menyebabkan meningkatnya kepadatan lalu lintas. Diperkirakan setiap bulan rata-rata kendaraan di Surabaya bertambah sekitar 17.483 unit. Kendaraan bermotor menyumbang sebesar 70-83% pencemaran udara di perkotaan. Besarnya kontribusi dari sektor transportasi menyebabkan turunnya kualitas udara. Particulate Matter (PM10) dan Total Suspended Particulate (TSP) merupakan polutan yang bersumber dari kendaraan bermotor. Pada penelitian ini pengukuran konsentrasi partikulat dilakukan dengan menggunakan Aerocet 531S Particle Mass Profiler and Counter dan pemantauan lalu lintas menggunakan video rekaman CCTV (Closed Circuit Television) di 6 titik sampling ruas Jalan Urip Sumoharjo, Jalan Diponegoro, Jalan Mayjend. Sungkono, Jalan Dr. Mustopo, Jalan Gemblongan dan Jalan Embong Malang. Tanaman sebagai penghalang disediakan di titik sampling ruas Jalan Diponegoro, Jalan Embong Malang dan Jalan Dr. Moestopo. Sampling dilakukan secara terus-menerus, mulai pukul 06.00-21.00 WIB pada satu hari kerja dan akhir pekan (Minggu). Total waktu yang dibutuhkan ialah 180 jam (6 lokasi x 15 jam x 2 hari x 1 pengulangan). Pengukuran dan pemantauan kendaraan dilakukan secara bersamaan agar mendapatkan kondisi paparan yang representatif. Analisis multipel regresi liniear diperlukan untuk mengetahui hubungan fungsional diantara variabel hari kerja dan akhir pekan, jam puncak dan non jam puncak, ada dan tidak adanya tanaman di trotoar, kelembapan, suhu, kecepatan dan arah angin serta jumlah kendaraan. Video rekaman CCTV digunakan untuk menghitung jumlah kendaraan dan mengklasifikasikan jenis sumber partikulat. Berdasarkan hasil penelitian diperoleh saat hari kerja konsentrasi rata-rata PM10 di titik sampling Jalan Diponegoro 444,256 µg/Nm3 melebihi baku mutu 0,61%; Jalan Dr. Moestopo 440,059 µg/Nm3 melebihi 1,10%; Jalan Gemblongan 456,542 µg/Nm3 melebihi 8,3% sedangkan konsentrasi TSP pada seluruh lokasi sampling tidak melebihi baku mutu. Pada akhir pekan konsentrasi PM10 dan TSP seluruh lokasi sampling tidak melebihi baku mutu. Berdasarkan analisis regresi liniear berganda diperoleh konsentrasi PM10 saat hari kerja lebih besar 73,468 µg/m3 dan konsentrasi TSP lebih besar 77,808 µg/m3 serta tidak adanya tanaman di trotoar sebagai penghalang dapat meningkatkan konsentrasi PM10 16,013 µg/m3 dan konsentrasi TSP 8,341 µg/m3. ========================================================================================== Surabaya is the capital city of East Java and one of big city in Indonesia. The high number of economic, industry, and other activities caused the increasing of traffic jam. It’s estimated that the average amount of motor vehicle in Surabaya increase about 17,483 units every month. Motor vehicles produced about 70-83% of air pollution in urban area. This condition is reasonable considering high contribution from transportation sector caused the decreasing air quality. Particulate Matter (PM10) and Total Suspended Particulate (TSP) are pollutants which is sourced from motor vehicles. In this research, the particulate concentration measurements were carried out using Aerocet 531S Particle Mass Profiler and Counter and the traffic monitoring using CCTV (Closed Circuit Television) recording video in 6 sampling locations at Urip Sumoharjo Street, Diponegoro Street, Mayjend. Sungkono Street, Dr. Mustopo Street, Gemblongan Street and Embong Malang Street. Plants were provided as barrier at point sampling on Diponegoro Street, Embong Malang Street and Dr.Moestopo Street. Continously sampling were done starting at 6 AM until 21 PM on weekday and on weekend (Sunday). Total time required is 180 hours (6 locations x 15 hours x 2 days x 1 repetitions). Measurements and monitoring of motor vehicles were carried out simultaneously in order to get a representative exposure condition. Multiple linear regression method was used to know the functional correlation between weekday and weekend variable, peak hour and non peak hour, presence and absence of plants on sidewalk, humidity, temperature, wind speed, directions and number of vehicles. CCTV recording video was used to calculate the number of vehicles, and to classify particulate source. Based on the result of the study, it was found that the average PM10 concentration on workday at the sampling point in Diponegoro Street is 444,256 μg/Nm3, it exceeds the standard of 0.61%; in Dr. Moestopo Street is 440,059 μg/Nm3, it exceeds 1,10%; in Gemblongan Street is 456,542 μg/Nm3, it exceeds 8,3%; whereas the concentration of TSP at all sampling sites doesn’t exceed the quality standard. On weekend, the concentrations of PM10 and TSP throughout the sampling sites does’nt exceed the quality standard. Based on multiple linear regression analysis it was found that PM10 concentration on weekday is 73,468 µg/m3 higher and TSP is 77,808 µg/m3 higher, the absence of plant as barrier at the sidewalk increased the concentration of PM10 16,013 µg/m3 and TSP 8,341 µg/m3.
