HUBUNGAN LAMA KERJA DENGAN PAPARAN TIMBAL (PB) DALAM URINE PADA OPERATOR PERCETAKAN DI PT MANADO PERSADA MADANI

Abstract

Lead (Pb) is a heavy metal that is naturally present in the earth’s crust and is spread through natural processes and comes from various human activities.Increased levels of Pb in the air as well as the working enviroment and industrial waste that uses Pb. Printing operators or employees are one of the groups exposed to lead (Pb). The purpose of this study was to determine the relationship of work duration with lead exposure (Pb) in urine on printing operator at PT Manado Persada Madani.       This research is  a quantitative  study using observational analytic methods  with cross sectional design. The sample in this study were all workers  who served as printing operators, in sampling using cluster  sampling techniques as many as  13 people by  using two treatment  of sampling namely before work and after work.Bivariate analysis research results were  analyzed using the non parametric correlations test proving that there is a significant relationship between length of work  with lead levels in printing operators  with a correlation value = 0,852 with a strong correlation category. Statistically prove that there is a significant  relationship between the length of work with  lead levels in urine  in printing operators who obtain P = 1,000 values.
