Abstract
The use of a push system planting tool to plant corn seeds requires a lot of energy because workers act as controllers, so it often creates a physical and mental workload.Workloads that are too heavy and exceed work capacity can cause fatigue.This fatigue will eventually cause pain.Therefore, the purpose of this study was to study the physical workload of operators in operating corn seed planting equipment.The parameters of the research observed were the worker's pulse before and after work, oxygen consumption, and the operator's physical workload.The results showed that the worker's pulse can describe the workload as a manifestation of muscle movement when doing work.The greater the muscle activity, the greater the fluctuation of the pulse movement that occurs.The operator's workload is in the light to medium category.Oxygen consumption of workers is influenced by the intensity of the work done.Based on oxygen consumption data, it is known that the workload of this corn seed planting tool is still relatively low because workers still feel comfortable and safe while doing planting work.
