Paparan Emisi Gas Kendaraan dan Kebisingan Berhubungan Dengan Tekanan Darah Petugas Pengujian Kendaraan Bermotor

Latar belakang: Paparan polutan seperti emisi gas kendaraan dan kebisingan yang dihasilkan oleh aktivitas pengujian kendaraan bermotor dapat membahayakan kesehatan petugas. Berbagai literatur telah mengaitkan peningkatan tekanan darah yang dialami pekerja dengan paparan polutan di lingkungan kerja. Penelitian ini bertujuan untuk mengetahui apakah ada hubungan antara emisi gas kendaraan dan kebisingan terhadap tekanan darah pada petugas pengujian kendaraan bermotor.Metode: Penelitian ini menggunakan pendekatan kuantitatif dengan desain cross sectional. Penelitian dilakukan mulai dari Desember 2020 sampai Juni 2021. Populasi pada penelitian ini adalah 54 petugas pengujian kendaraan bermotor Dinas Perhubungan Kabupaten Deli Serdang dan keseluruhan populasi dijadikan sampel (total sampling). Pengukuran paparan karbon monoksida dan hidrokarbon menggunakan emission analyzer AET-2000S. Sedangkan pengukuran kebisingan menggunakan sound level meter. Data dianalisis dengan menggunakan uji Chi Square (α=0,05).Hasil: Hasil penelitian menunjukkan sebanyak 13 petugas terpapar karbon monoksida dengan paparan di atas nilai ambang batas. 25 petugas terpapar hidrokarbon yang melebihi nilai ambang batas. Sebanyak 21 petugas terpapar kebisingan melebihi ambang batas selama bekerja. Dari hasil pengukuran tekanan darah terlihat bahwa 20 orang memiliki tekanan darah di atas 140/90 mmHg. Uji statistik menunjukkan paparan karbon monoksida (0,006), hidrokarbon (0,014) dan kebisingan (0,001) berhubungan signifikan dengan peningkatan tekanan darah pada petugas pengujian kendaraan bermotor.Simpulan: Tindakan pencegahan yang disarankan berupa penggunaan alat pelindung diri selama melakukan pengujian kendaraan bermotor. Selain itu, perlu dilakukan pembatasan jam kerja untuk meminimalisir durasi paparan polutan pada petugas. ABSTRACT Title: Exposure to Vehicle Emissions and Noise in Relation to Blood Pressure Among Motor Vehicle Testing Officers Background: Exposure to pollutants, such as vehicle gas emissions and noise generated by motor vehicle testing activities, can jeopardize officers' health. Various studies have linked the increase in blood pressure experienced by workers with exposure to pollutants in the work environment. This study aimed to determine whether there is a relationship between vehicle gas emissions and noise on blood pressure among motor vehicle testing officers.Method: This study used a quantitative approach with a cross-sectional design. This study was conducted from December 2020 to June 2021. The population in this study was 54 motor vehicle testing officers of the Deli Serdang Regency Transportation Office, and the entire population was sampled (total sampling). Carbon monoxide and hydrocarbon exposure was measured using an AET-2000S emission analyzer. Noise measurements were performed using a sound-level meter. Data were analyzed using the chi-square test (α=0.05).Result: The results showed that 13 officers were exposed to carbon monoxide with exposure above the threshold value. 25 officers were exposed to hydrocarbons that exceeded the threshold value. A total of 21 officers were exposed to noise exceeding the threshold during work. Blood pressure measurements showed that 20 people had a blood pressure above 140/90 mmHg. Statistical tests showed that exposure to carbon monoxide (0.006), hydrocarbons (0.014), and noise (0.001) were significantly associated with increased blood pressure in motor vehicle testing officers. Conclusion: To mitigate the risks associated with pollutant exposure, it is recommended that workers engaged in motor vehicle testing wear personal protective equipment (PPE) and that working hours are limited.
