Abstract:
Data Structure is a compulsory 4th semester subject in the Department of Informatics, Atma Jaya University, Yogyakarta, Indonesia. There are 121 students enrolled in this subject, all of whom need to be allocated to classes. This fact raises three questions. Firstly, what is the appropriate number of classes? Secondly, how do we allocate those students into classes? Thirdly, which student belongs to which class? The answer to the second and the third questions for a given number of classes was formulated in (Susanto and Ernawati. 2006) by employing the Fuzzy Clustering concept. As a development to (Susanto and Ernawati, 2006) and (Susanto and Ernawati, 2005) this research tries to answer the first question by employing the Partition Coefficient and Exponential Separation (PCAES) Index.
