Working climate with fatigue levels of timber industry workers in probolinggo

The high-temperature work environment is an additional burden of heat pressure that results in the occurrence of subjective deficiencies in the worker and may cause disruption to the workforce. The purpose of this study is to analyze the relationship between work climate with the level of fatigue in workers in PT. Kutai Timber Indonesia Probolinggo. This research use analytic survey method with the cross-sectional approach and sampling technique using Cluster Random Sampling of 134 samples in Production I section that is hot press, shikumi, and putty. The study was conducted in January 2018. Data were analyzed by Chi-Square statistical test.

The result of the research shows that most of the working climate that exceeds threshold value with high fatigue category is 70 respondents (52,5%), almost half of them are 40 respondents (29,9%) with the moderate level of errors. While in the working climate that does not exceed the threshold value with the category of fatigue rate is a small number of 20 respondents (14.9%) and high fatigue rate of 4 respondents (3.0%). Calculation of Chi-Square statistic test with significance level α = 0,05 obtained result ρ = 0,000 (0,000 <0,05) then H0 is rejected, so there is the significant relation between work climate with fatigue level at the worker in PT.KTI (Kutai Timber Indonesia) Probolinggo City. To minimize heat stress from a work climate that exceeds threshold value, it is better for the company to use an exhaust fan where the heat from the working environment sourced from the zinc roof and the production machinery is pulled out of the environment with lower temperatures, periodic health checks on labor, before work stretching for 3–5 minutes and suggest workers consume water every 20 minutes in the work.
