Corn has its own charm in the agricultural industries, especially in Tanjung Bintang. This crop can be consumed as staples in food and feed industry. In corn production chain, post-harvest requires some special attentions, as its price tends to decrease due to incorrect post-harvest handling. The increase of corn demand must be followed by higher productivity that can be identified from several work elements, which consist of cutting (Ct), transporting (Tr), and milling (Mi). In this moment, the post-harvest process is carried out by both men and women. The post-harvest process of corn was performed when it had been dried on the field. Hence, there is no drying process was needed. The purpose of this study was to determine the fatigue level of corn farmers in post-harvest activities both subjectively and objectively. The objective method used in this study was direct observation in the field by measuring the heart rate using a HRM. On the other hand, the applied subjective method was the SOFI questionnaire data. The results of the questionnaire showed that there were significant differences in the dimensions of physical fatigue, which consists of lack of energy (LE), physical exertion (PE), and physical discomfort (PD) with the general transportation showing the highest fatigue and the lowest was milling. The subjective fatigue dimensions, Lack ofmotivation (LM) and sleepiness (S) did not indicate any significant difference due to the majority of the activities were the physical work. In the objective measurements, the IRHR showed that the highest IRHR value in the transporting and grinding was more than 1.50. This value indicated the work element classified as heavy work. In conclusion, the subjective and objective measurements appointed the transportation (Tr) had the highest level of fatigue. © 2020 Published under licence by IOP Publishing Ltd.
