This study aimed to evaluate the activity of feeding laying hens at poultry farm. Observations were made of all workers in charge of providing animal feed totaling 13 workers. The work observed was the process of loading animal feed on baskets until the final distribution. The evaluation was based on the results of the Nordic Body Map questionnaire, physiological workload measurements, National Institute for Occupational Safety and Health (NIOSH) lifting calculations. The worker’s physiological workload was taken into account, and it revealed that there has been an increase in work pulse rate obtained Cardiovascular Load (%CVL) is in the range of 58%-72% and the energy consumption of workers ranges from 4.10-6.59 Kcal/minute. Thus, physiologically the work activities carried out by the feeding workers are categorized as moderate work, and it is necessary to improve the work activities. Meanwhile, evaluation using the Recommended Weight Limit (RWL) and Lifting Index (LI) in the process of animal feed showed RWL values ranged from 8.61 kg-10.19 kg, and LI values ranged from 1.87 to 2.50. This number is beyond the limit for manual lifting. |
