Asap kendaraaan bermotor merupakan suatu polutan yang sangat berbahaya bagi lingkungan. Asap tersebut mengandung timbal bromida (PbBr) yang merupakan sisa hasil pembakaran bensin, dimana bensin yang digunakan mengandung campuran tetrametil lead (TML) dan tetraetil lead (TEL). Timbal yang masuk ke dalam tubuh menyebabkan berbagai efek dalam tubuh, salah satunya yaitu efek pada darah. Individu yang rentan terpapar timbal adalah sopir angkot. Sopir angkot rata-rata bekerja selama 10-11 jam perhari, sehingga perlu dilakukan penelitian mengenai hubungan masa kerja dengan gambaran darah pada sopir angkutan kota (angkot) yang terpapar Pb di Purwokerto. Tujuan penelitian adalah mengetahui hubungan masa kerja dengan kadar Pb dalam darah pada sopir angkot di Purwokerto dan mengetahui hubungan kadar Pb dengan gambaran darah pada sopir angkot di Purwokerto. Materi yang digunakan dalam penelitian adalah sampel darah sopir angkot di Purwokerto. Metode penelitian yang digunakan yaitu purposive random sampling dan wawancara terhadap responden (interview). Variabel bebas dalam penelitian adalah masa kerja sopir angkot sedangkan variabel terikat dalam penelitian adalah kadar Pb darah dan gambaran darah yang dibatasi pada jumlah leukosit, trombosit, nilai MCV, MCH dan MCHC. Hubungan masa kerja dengan kadar Pb dan hubungan kadar Pb dengan gambaran darah meliputi jumlah leukosit, trombosit, MCV, MCH dan MCHC dianalisis dengan uji pearson corellation. Hasil penelitian menunjukkan hubungan masa kerja dengan kadar Pb diperoleh nilai koefisien korelasi sebesar 0,002. Hubungan masa kerja dengan jumlah leukosit berturut-turut dari leukosit normal, leukositosis dan leukopenia adalah -0,059; 0,367 dan 0,877. Nilai koefisien korelasi hubungan masa kerja dengan jumlah trombosit normal, trombositosis dan trombositopenia yaitu -0,209; -0,141 dan -1, sedangkan nilai koefisien korelasi nilai MCV, MCH dan MCHC normal yaitu 0,123; 0,083 dan -0,038. Semakin lama masa kerja dapat meningkatkan kadar Pb darah sopir angkot di Purwokerto tetapi menurunkan jumlah leukosit, trombosit, sedangkan nilai MCV, MCH dan MCHC tidak terpengaruh oleh lama masa kerja.

Vehicle fumes is a pollutant that is very harmful for environment. The smoke contains lead bromide (PbBr) which is the residue of the gasoline. The gasoline which is used contains TEM (tetramethyl lead) and TEL (tetraethyl lead). Lead that gets into the body causing various effects, such as blood. Individu that susceptible to be affected by lead are public transportation drivers. Average public transportation drivers work for 10-11 hours a day, so it is necessary to study the relationship between job period with the blood representation of public transportation drivers that exposed by lead in Purwokerto. The research objective was for knowing the relationship between working period with the blood lead concentrations and knowing the relationship between working period with the blood representation of public transportation drivers in Purwokerto. The material used in the study were blood samples of public transportation drivers in Purwokerto. The research method used was purposive random sampling and interviews of respondents. The independent variable was working period of public transportation drivers while the dependent variable in the study were blood lead levels and blood representation that limited to the number of leukocytes, platelets, the value of MCV, MCH and MCHC. The variables number and value were performed by statistical tests used Pearson corellation. The research results showed that correlation value of relationships the working period with lead concentrations was 0,002. The relationship of the working period with the number of leukocyte from normal leukocyte, leukocytosis and leukopenia are -0,059; 0,0367 and 0,877. The value of coefficient correlation of working period with the number of normal trombocyte, trombocytosis and trombocytopenia are -0,209; -0,141 and -1. Meanwhile, the value of coefficient correlation normal of MCV, MCH and MCHC are 0,123; 0,083 and -0,038. Longer working period can increase blood lead levels of public transportation drivers in Purwokerto but decrease the number of leukocytes and platelets, while the value of MCV, MCH and MCHC are not effected by longer working period.
