| Summary: | Human resources analysis, especially at the competency based talent
analysis, is the important thing to do by the institution for their efficiency in
human performance employee. Many institutions try to do talent analysis to do the
right staff recruitment that have good capabilities. That�s why Bali State
Polytechnic (PNB) also applies this analysis.
To analyze the human resources competency can be done by analyzing the
human talent. One of the conventional method that common to use is C4.5
algorithm. Conventional C4.5 method uses data crisp. In this study, it used a
linguistic term as an input data because the talent test is expressed using the
language (linguistic term) and it is a set of data in fuzzy form. Fuzzification
process in preprocessing data was done to produce the input data in fuzzy form.
The results shows the use of fuzzy logic in a stage of preprocessing and the
C4.5 algorithm in forming decision tree (fuzzy C4.5) can be used as an alternative
solution to process the input dataset numeric format, where the number of
linguistic terms of an attribute directly and significantly affect the accuracy of the
system. The more the number of linguistic terms, the lower the accuracy of the
system.
The result of this research is obtained in the use of fuzzy logic in that stage
of pre-processing and algorithms C4.5 in forming the decree ( fuzzy C4.5 ) can be
used as solution alternative to cultivate dataset inputs numerical, where's the
number of linguistic term of an attribute influential directly and significantly to
the accuracy of the system . The more linguistic term so the lower the accuracy of
the system
