Abstract

Research on the application of the Indonesian National Standard (SNI) of Bali cattle by cluster analysis and biplot aims to provide a visual picture in the form of tables and graphs, so that it is easier and faster and more communicative in making decisions, whether the cows studied are included in class I, class II, or class III based on SNI Bali cattle. This study was conducted on 70-year-old adult female cows of 70 animals raised at the Integrated Farming System (Simantri) in Badung regency. The data obtained were analyzed by cluster analysis and biplot, as variables were shoulder height, body length and chest circumference, while as objects were 70 adult cows and 3 classes of Balinese cattle based on SNI of Bali cattle as object identifiers. The results obtained that the application of SNI for Bali cattle can be done by cluster analysis and biplot and both analyzes give the same results to the grouping of Bali cattle objects based on SNI for Bali cattle. Grouping by cluster analysis is easier to see based on the cluster membership obtained, whereas with biplot analysis provides additional information about correlations and diversity between variables.

Highlights

Bali cattle have been established through Keputusan Minister of Agriculture Number: 325 / Kpts / OT.140 / 1/2010, as a native Indonesian cattle family and has spread throughout Indonesia
The results of cluster analysis of 70 female Bali cattle and 3 objects identifying SNI class I, class II and class III can be drawn with a dendogram graph like Figure 2
The results of cluster analysis of 70 Bali cattle over the age of 24 months are mostly in class III and none are outside the class, this shows that the Bali cattle raised in Bali cattle farms have good management

Summary

Introduction

Bali cattle have been established through Keputusan Minister of Agriculture Number: 325 / Kpts / OT.140 / 1/2010, as a native Indonesian cattle family and has spread throughout Indonesia. Bali cattle breeding standards need to be established as a reference for businesses in efforts to develop Bali cattle. Speaking there are two ways of presenting data that are often used are tables or lists and graphs or diagrams [2]. Demonstration of data with pictures (graphs) has been long and often done, and is highly recommended in an analysis. The display of data in this form is more favored than the presentation in the form of tabulation of numerical data or in the form of narration, because it is more interesting, more informative because it can provide more information and is more communicative so that it is easier to understand and can be said tobe more artistic in form, composition , and colors so that it is more beautiful [3]
