| Summary: | Work in the agricultural sector tends to be strenuous and high-risk. This study aims to
evaluate the workload of farmers by measuring their maximum oxygen capacity and
heart rate. This study consists of two stages, the first stage by measuring oxygen
capacity and heart rate in the laboratory and the second stage by measuring heart rate
when farmers work in the field. The first stage of measurement in the laboratory is
using the Bruce protocol with maximum method. There were 20 farmer respondents
was collected from the first stage. The first stage of measurement data, a linear
regression model was generated to be used in the second stage. The second stage is to
estimate the oxygen capacity of the farmers when they work in the field. The results of
the first stage analysis showed that the mean and standard deviation of the maximum
oxygen volume (VO2max) was 1969.71 L/min ± 496.47 or 29.39 mL/kg/min ± 6.89 and
the value of oxygen capacity (VO2) on the treadmill obtained a mean and standard
deviation of 1185.3 mL/kg/min ± 254.74 or 17.61 mL/kg/min. The results of the second
stage, estimation using the regression model formula from the first stage, resulted in
an estimated oxygen consumption value of 1.4 L/min. The comparison of the estimated
oxygen consumption value with the maximum oxygen volume gives a percentage of
74%. This result shows that the farmer is close to heavy work level. All of the
measurement and evaluation of workload shows that the farmers have an excessive
workload experience. An ergonomic intervention is needed to reduce the workload of
farmers to reduce the risk of occupational diseases and accidents at work. This study
suggests improving the work system and use of work aids. Automatic and affordable
tools are needed to help and complete the work of the farmer.
