Association between duration working with lung disruption condition using pulmonary vital capacity (PVC) test on lathe worker at Yogyakarta, Indonesia

Background: For the past decade, pulmonary fibrosis occurred due to excessive connective tissue in the lung caused by inflammation. Inhaled aluminum constantly has been thought as a key factor for pulmonary fibrosis for workers. Within the next few years, aluminum ash would become toxic inside the body and cause a hardening or fibrosis of the lungs. The present paper aims to analyze association between duration working with lung disruption condition on lathe workers in Z industry, Yogyakarta. Method: The research used a cross-sectional design. The sample was 16 lathe workers at Z Industry, Yogyakarta. Independent variable were age, period employment, and duration of work. The dependent variable was lung disruption. Measurement of lung disruption used pulmonary vital capacity test. Data analysis was using chi-square test and Risk Prevalence (PR). Result: Age and the period of employment had a quite weak association with lung disruption (p=0,158;0,279). While the duration of work has a strong association with lung disruption (p=0,729). Conclusion: Duration of work has a strong association with lung disruption. This is caused by a worker which inhaled aluminum dust continuously, aluminum dust would be accumulated, becomes toxic and caused parenchyma tissues damaged in the lung.
