The patterns of phonemic integration of rhyme found in the research are those which are free or are not fixed. The beginning rhyme occurs due to the iterations of words or lines. In addition, the middle and end rhymes occur because they follow the end phonemes of the former lines. The realization of alliteration, assonantion, euphony, cacophony, phonemic symbol occurs linearly in one line or many lines in one couplet. The pattern of alliteration always occur not only at the beginning syllables but also at the end syllables, but that of assonation always occurs in the open syllable. In addition to plosive, sibilant, and lateral sounds, in the poetries of W.S. Rendra are nasal sounds also found.
