Department of Informatics in UMS has three concentrations. Due to these three
concentrations, the students are required to choose one of these three concentrations at
the end of the fourth semester. Currently, students determine the concentration based
on the students’ own wishes without a system which gives the students consideration
in selecting their concentration. By designing clustering k-means application, the
researcher expects it can provide the students source of information to determine their
class concentration. The variables used are the value of the dominant subjects of each
concentration ranging from semester 1 to 4, the variables of information system and
enterprise (Basic Web Programming, Algorithms and Programming, Introduction to
Information System, Data Base System) concentrations. Computer network and
multimedia (Data Communication, Computer Network, Practicum Computer Network,
Operation System). Software engineering and animation (linear algebra and matrix,
Algorithms and Data Structures, Discrete Structure 2, Digital system). The result is
that the students of 2011 academic year data are distributed into 3 cluster, cluster 1
with centroid point (3,333 ; 3,548 ; 3,098) and cluster 2 with centroid point (0,915 ;
1,110 ; 0,773), also cluster 3 with centroid point (2,682 ; 3,221 ; 1,880). The members
of cluster 1 are recommended to take the Computer Network and Multimedia
concentration, the members of cluster 2 are recommended to take the Software
engineering and animation concentration then the members of cluster 3 are
recommended to take the Information System and Enterprise concentration
