Abstract

A survey was conducted to develop an anthropometric data and working profile of female farmers in Cavite. Thirty-eight body parts were measured from 62 female farmers. These body parts served as basis in evaluating the IRRI 4-Row Ultralite Rice Transplanter. It was found out that the working population has an average age of 46.30 years old and most of them are married. About 53.23% of the female farmers are cultivating less than a hectare of farm and 41.25% own the area they cultivate. The 83.87% of the female farmers are involved in planting operation as well as harvesting. Results showed that the farming population in the province has an average height of 151.77cm. The values of5ᵗʰ and 95ᵗʰ percentile were also determined and served as basis in evaluating the IRRI 4-Row Ultralite Rice Transplanter. The handle of the transplanter was evaluated. The diameter of the handle is 2.90cm and is less than the 4.19cm grip diameter of the 5ᵗʰ percentile farmer. Posture analysis while operating the IRRI 4-Row Ultralite Rice Transplanter was done. Two operating positions were included in the analysis. These were planting and the pul;ling positions. The analysis limits the positions within the range of comfortable motion. The distance of the forward foot of the farmer from the skid of the transplanter was evaluated. The distance must be greater than 15cm. This distance gives the 10cm required distance for the spacing of the seedlings and 5cm for the allowance for safe movement. The computations revealed that the 5ᵗʰ percentile female farmers has distances of 39.32cm, 43.85cm, and 46.30cm for the arm flexion angles of 90°, 100°, and 110° from the horizontal, respectively for pulling position. The 95ᵗʰ 90°, 100°, and 110° from the horizontal, respectively for pulling position. The 95ᵗʰ percentile female farmer has distances of 24.34cm , 32.23cm and 36.80cm for the arm flexion angles of 90°, 100°, and 110° from the horizontal, respectively for planting position and 17.50cm, 24.51cm, and 25.58cm for the arm flexion angles of 90°, 100°, and 110° from the horizontal, respectively for pulling position. These values suggest that 90% of the female farmers can operate the transplanter with less experienced back pains and injuries. The female farmers can operate the transplanter efficiently since it is ergonomically fitted to their body dimensions.
