It takes the largest demand for labor and time spent in the sugar palm cultivation. The main objective of the study was to investigate human energy expenditure in harvesting sugar palm in Malaysia. Workers’ workload and productivity in harvesting sugar palm were also analyzed. Relevant physical properties of sugar palm tree, heart rate, and human energy expenditure and worker productivity as well as in harvesting sugar palm were recorded... |
