Abstract

Efforts to improve the quality of the results of milking cow’s milk can not be separated from the quality of feed for cattle. Dairy farm in dire need of high-quality cattle feed. However, to support the fulfillment of a good cow feed mixer also needed a good feed anyway. On farms in the area Pujon, Batu Malang, there are activities that are less efficient, in terms of time and energy. One was in the process of mixing the feed are still using manual equipment, bending operator position in a long time, and the results are not in accordance with the composition of mortar required.

This study focuses on the means for stirring fodder with application of ergonomics. The first stage is to calculate working time data feed stirring with manual tools for standard time and standard output, as well as calculate the anthropometric data. The position of the operator is established, then the anthropometric data are used for animal feed mixer include high elbow in a standing position, stretch the hand and arm’s reach to the side. The second stage is to make the design as per calculation anthropometry and technical considerations to then make animal feed mixing machine. The last stage is to calculate working time data feed stirring with design tools to get the results of standard time and standard output.

Automatic feed mixing machine that is the dimension 143 x 57 x 109 cm³. Driving force used is 1-phase electric motor with a power of 1 HP. The results showed that the Standard

Time (Wb) decreased by 0:17 min / kg ie from the old tool (manual) 0:25 min / kg to 0:08 min / kg in tool design results, and increased output Standart (Os) of 8.5 kg / min with percentage of 212.5% from 4 kg / min to 12.5 kg / min.
