STUDI PAPARAN KONSENTRASI GAS KARBONMONOKSIDA (CO) DI LINGKUNGAN KERJA PETUGAS PARKIR DAN POLISI LALU LINTAS DI KOTA PADANG

Abstract

ABSTRAK

Studi paparan konsentrasi gas karbonmonoksida (CO) terhadap petugas parkir dan polisi lalu lintas bertujuan untuk mengetahui tingkat paparan yang diterima di udara tempat kerjanya dan melihat beberapa variabel yang mempengaruhi konsentrasi gas CO. Penelitian ini dilakukan di areal parkir tertutup di pusat perbelanjaan terbesar Kota Padang (Plaza Andalas dan Rocky Plaza Hotel) dan di 5 pos jaga Polisi Lalu Lintas. Pengukuran gas CO dilakukan dengan menggunakan CO meter dengan electrochemical sensor dan dioperasikan selama 1 jam di setiap titik pengukuran. Pengukuran CO di areal parkir tertutup menunjukkan bahwa konsentrasi CO di udara kerja petugas parkir Plaza Andalas dan Rocky Plaza Hotel melebihi batas baku mutu, sementara jumlah kendaraan yang mengkontribusi gas selama pengukuran di areal parkir memiliki hubungan yang kurang kuat(R²=6,5%-51%) terhadap peningkatan konsentrasi CO. Sedangkan dari hasil pengukuran gas CO di 5 pos jaga polisi lalu lintas menggambarkan bahwa konsentrasi CO masih berada di bawah baku mutu, dan volume lalu lintas sebagai variabel bebas yang diduga berpengaruh memiliki hubungan yang kurang kuat (R²=45%) terhadap peningkatan gas CO di udara tempat kerja Polisi Lalu Lintas.

ABSTRACT

Study of carbon monoxide concentration (CO) of the parking attendants and traffic police checkpoints aimed to determine acceptable levels of exposure in the workplace area and to see some of variables that affect the concentration of CO. The research was carried out in the parking lots of Padang's largest shopping center (Plaza Andalas and Rocky Plaza Hotel) and in 5 traffic police checkpoints. CO measurements were carried out using a CO meter with an electrochemical sensor and operated for 1 hour at each measurement point. Measurement of CO in the covered parking area indicated that the concentration of CO in the air Andalas Plaza parking attendant job and Rocky Plaza Hotel exceeded the quality standards, while the number of vehicles that contributed during the measurement in parking areas have a less strong impact (R2 = 6.5% - 51%) of the increase in CO concentration. While the results of measurements of CO gas in 5 traffic police checkpoint illustrated that CO concentrations were still below standards, and traffic volumes as independent variables was thought to have influence a less strong impact (R2 = 45%) to the increase in CO gas air at the Police workplace.
