ANALYSIS OF THE PHYSICAL WORKLOAD OF SUGARCANE HARVEST WORKERS AS THE BASIS FOR DETERMINING THE LENGTH OF REST BREAK AT BONE ARASOE SUGAR FACTORY
Abstrak
Arasoe Bone Sugar Factory is one of the sugar factories in Bone Regency, South Sulawesi. The production process
at this company entirely uses machines that run automatically. However, the sugarcane harvesting activity is still
carried out manually. All sugarcane harvesting activities result in physical workload on workers, especially when
lifting sugarcane since in one loading, the workers are able to lift more than 30 kg of sugarcane. This activity is
carried out repeatedly which results in fatigue on the harvest workers. The other factors that affect fatigue on the
harvest workers are the harvested sugarcane plantations that can reach approximately 7 hectares in area and the
work that lasts for 7 hours each day. This study aims to determine how much physical workload is experienced
by sugarcane harvest workers and to determine how long the rest break is based on the physical workload that is
obtained while working for the sugarcane harvest workers. The assessment of physical workload was carried out
using the Cardiovascular Load (%CVL) method and the calculation of the length of rest break was carried out
using a physiological approach. Based on the results of calculating the percentage of Cardiovascular Load
(%CVL), it was discovered that all respondents experienced fatigue consisting of 5 workers with a %CVL of
≤60%, 13 people with %CVL of ≤80%, and 2 people with %CVL of ≤100%. Therefore, all respondents
were included into the category of heavy physical workload. The optimal rest break is 80.79 minutes, while the
rest break given is only 60 minutes. Hence, an additional 20.79 minutes of rest break is needed. The rest break
of 20.79 minutes is used for spontaneous breaks, i.e., short break after the workload
