One of the negative effects from activity on coal yard location is air pollutant by coal dust. Coal dust that inhaled can caused the worker have lung function disorder risk. There are two prominent of lung function disorder that is restriction and obstruction. But there are also mixed disorder that compounding between restriction and obstruction. The purpose of this research was to analyze the correlation between total and inhaled coal dust amount and individual characteristic with lung function disorder of coal yard workers at PLTU X Jepara. This research was an observational study with cross sectional approach. The subjects of this study were all of workers in coal yard location by 40 persons as respondents. The result of this research showed that lung function disorder that happened in to the workers was restriction lung function disorder, which was from 35 respondents there were 25,7% were normal, 71,4% with light restriction and 2,9% with average restriction. Result from spyrometer tests showed that there was no obstruction and mixed lung function disorder for workers. The result of total dust amount in 5 locations using High Volume Sampler showed was dust amount is bigger than Threshold Limit Value. Based on Rank-spearman statistical tests, it was obtained the value of total dust amount (p-value = 0.001), and from the Pearson correlation test of inhaled dust amount (p-value = 0.000), smoking habit (p-value = 0.000), age (p-value = 0.533), nutrient status (p-value = 0.101) and exercise habit (p-value = 0.894). The conclusion of this study, there was a significant correlation between total dust amounts, inhaled dust amount and smoking habit with lung function disorder, whereas there was no correlation between age, nutrient status and exercise habit with lung function disorder.
