The Comparison Between Norotate and Promax Rotations of Biplot Simulation in The Management of Bali Cattles Breeding Farms on Integrated Farming System

This study aims to determine the comparison between Norotate Rotation and Promax Rotation (90) of Biplot Simulation in the management of BaliCattle Breeding Farmson Integrated FarmingSystem (Simantri). It usedto determine the difference ofcoordinatesbetween the variables and also obtain theinformation about the difference in the proximity of the coordinates between livestock groups.The study conducted on Simantri who had livestock groupsin Badung Regency, Bali in which the data collected were analyzed by factor analysis with Norotate Rotation and Promax Rotation (90). The variable of this study was a livestock managementwhich included management of cows, calves, feed,cowshed, environmental,andthe objects of the study were thelivestock groups. The Biplot simulation used to determine the coordinates of the livestock groupsdetermined based on the Factor Scores Method Regression Analysis.The results with different rotations caused differences inthe magnitude of the arrow angles and directions between management of cows, calves, feeds, cowshed and environmental which also followed by differences in the coordinate systems of the livestock groups. The angle between management of cows, calves, feeds, cowshed, and environmental do not show the magnitude of the correlation between them. It can be stated that the coordinates of Livestock groupson Promax Rotation (90) are more specific than Norotate Rotation, thereforeit is easier to distinguishthe different scoresbetween the variableson the Livestock groups.
