The Ergonomic Shooting Net Design for Pond Farmers

Abstract

The application of ergonomics principle that all working activities can caused workers physical and mental stress. Ergonomics strive for this pressure is still within tolerable limits, satisfactory performance results, and the health and welfare of workers can be increased. If this excessive loads occurred, it will increase some errors and injury. This study aims to making the systematic design for conceptual design of a innovation product using Pahl & Beitz methods. The Variables in this research are hand length (HL), Grip diameter (GD), and length of index finger (LIF) along designing and making nets in accordance with the Anthropometry data. The results of the study recommend nets specification corresponding to the farmers. The length of the shooting net is between 75 cm to 64 cm (0.75 to 0.64 meters), The diameter of the PVC (pipe) is 7.5 cm (0.075 meters), The length of the shooting nets handle is between 5 cm (0.05 meters), The weight of product is 5.5 kg, The nets diameter size is 2.5 m, and The filling pressure of the wind at the automatic firing line is with a maximum limit of 80 psi (5.51 bar) and a minimum of 30 psi (2,068 bars). its use is also very easy and practical because it is enough to fill the wind, then pressing the first lever that is already there to throw or fire the net and to pull it electrically just by pressing the second lever on this automatic firing net. For users, it is also very convenient because there is no need to carry and throw conventionally, because this mesh has been prepared a buffer that serves to support the mesh automatically. So, this automatic shooting net can reduce the burden, hand and hip injuries for its users.
