Abstract

Chainsaw usage is very common during logging operations. Using a chainsaw requires a sufficiently high level of skills as it is a job which is difficult, dirty, and dangerous (commonly known as 3D). It is imperative to use a simulation model to practice the chainsaw skills before its actual operation. We have created a model for skill training and to determine the relationship between improvement of skills and time spent on the job, as well as other elements that may have an impact on skill development. The results show that the delimbing times were not significantly different between the skilled and unskilled sample groups. According to the statistical analysis, there was no significant difference between the sample groups. However, the learning curve for the unskilled sample group indicated to a wider distribution range. The lead time tended to stabilize in 7 or 8 training rounds, compared to the skilled sample group, whose the lead time stabilized in 5 or 6 rounds. It was found that repetitive experiments resulted in better delimbing skills and a reduced time to complete the job. When the sample was segmented by gender, the difference between males and females was not statistically significant. The body mass index (BMI) classification had a statistically significant influence on the pruning time. This might be due to the chainsaw's weight causing the test subject to experience varying levels of weariness, which resulted in an increased time to complete the job, especially for those who are thin. Such a model can help subjects gain proficiency and familiarity with the chainsaw, which in turn will make it easier to efficiently manage the equipment in the field.
