Analysis of Workload of Corn Seed Planting Equipment Operators Integrated with Fertilization Equipment

Introduction: The use of corn seed planting tools integrated with fertilizing tools requires a lot of energy because workers act as controllers, so that it often causes physical and mental workloads. Workloads that are too heavy and exceed work capacity can cause fatigue. This fatigue will eventually cause pain. Objective: The objective of this study is to investigate the physical workload of operators in operating corn seed planting tools integrated with fertilizing tools in supporting SDGs. Method: The methodology used in this study includes pulse observations carried out 5 times on each operator for 3 working days. The pulse before and after implantation was measured by measuring the pulse on the wrist artery with the 10-beat method. Results and Discussion: 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. Research Implications: The practical and theoretical implications of this study prove that the greater the muscle activity, the greater the fluctuation of the pulse rate movement that occurs. Workers' oxygen consumption is influenced by the intensity of the work being done. Originality/Value: This study contributes that the worker's pulse rate indicates workload as a manifestation of muscle movement while working. The workload of this corn seed planter is still relatively low because workers still feel comfortable and safe when using the corn seed planter.
