Results: The result showed that from 135 respondents who had been studied by the researcher, it was found that 115 respondents (85%) had positive lumbago. 80 of 135 respondents (59%) had more than 10 years of service, and 114 of 135 respondents (84%) sat for more than 9 hours per day and 122 of 135 respondents (92%) were in ergonomic sitting position. Based on the Logistic Regression test based on the omnibus test of the model, it showed a significance value of p-value = 0,000 <α = 0.05, it meant that H0 is rejected and H1 is accepted, this means that there was a joint effect between the factors of work period, length of work and sitting position of lumbago incidents in hand- rolled clove cigarette workers. Based on the value of Exp (B) with the highest value Exp (B) = 187,663 it can be concluded that the most dominant factor that affecting the lumbago event is the sitting position.
