Abstract
Human labor energy still provides a large and dominant contribution in rice cultivation in Indonesia. This study is specified to determine human energy needed for primary tillage operation in paddy cultivation practices in Padang Pariaman, West Sumatera Indonesia. The objectives of this research are to analyze human energy expenditure for primary tillage operation and to compare between real-time measurement and conversion factor of energy. The data were collected with three different plot areas with average size 30 m × 25 m. The analysis of human energy consumption conducted by two methods (predicted energy using conversion factor value of energy and real-time energy using Garmin Forerunner 35). The result shows that the real-time measurements of labor energy expenditure for primary tillage operation were 17.7291, 19.2857, and 12.2483 MJ/ha, respectively. However, the labor energy defined by the conversion factor were 13.3568, 14.0141 and 12.7498 MJ/ha, respectively. Thus, tillage operation with average heart beat rate was 127 bpm, it could be categorized as heavy work. This information is needed as a basis to improve and recommend designing of agricultural equipment and machinery, and also tools to reduce the use of labor energy.
