Based on Table. 1, we can see that optimal cluster formed with use
FCM algorithm that is in cluster 2 with highest MPC value as big as
0.5552903 with amount iteration as much as 35 and time computing
0.11 seconds.

In Table. 2, we can conclude that Cluster 2 is optimal cluster formed
for FPCM method. This thing seen from highest MPC value that is as
big as 0.5552900 with amount iteration as much as 21 and time
computing 0.07 seconds.
