      Then, if we pay more attention to the columns of Unlexicalized Filled Pauses from Table 4.1, both the first and the seventh semester students produced a similarity and the differences. The similarity is both the first and the seventh semester students produced ee as the most frequently used type and ehm as the second frequently used type. Then, the difference is the first semester students produced ee lesser than the seventh semester students, which is 27.85% : 38.68%. Another difference is the first semester students did not produce oh, while the seventh semester students did not produced ah, nah, and huh as their unlexicalized filled pauses.
      Examples of unlexicalized filled pauses:
   B:  Ya, me too, ee, since I disagree with the existence of this apartment, I I will also disagree with, even with the 24 hours a day ee in the construction working because ee as what I said before, the road is getting smaller... it's a two way roads, so ehm, the traffic, ehm, that something that cannot be avoided...
In these utterances, B produced a lot of unlexicalized filled pauses, that is ee for three times and ehm for two times when s/he was talking her/his opinion about the negative impact of Petra Square Apartment's 24 hour construction work. B used several unlexicalized filled pauses to fill the pause and to hesitate. These unlexicalized filled pauses are easily identified because they have no meaning due to basically they are vocalizations.Â
After that, when we see the columns of Lexicalized Filled Pauses from Table 4.1, we can find a similarity and the differences as the result of the different semester of the respondents. The similarity is both the first and the seventh semester students produced yeah as the most frequently used type. Then, the difference is the first semester students did not produce I guess, like, sort of, what is it, and what else, while the seventh semester students did not produced well as their unlexicalized filled pauses. Another difference is the first semester students produced I think more than two times bigger than the seventh semester ones, which is 4.11% : 1.42%. Besides, the first semester students produced well for 6.96% (the second biggest number of lexicalized filled pauses after yeah), while none of the seventh semester students produced it. Ya, yeah, and yes were produced less frequently by the first semester students than the seventh semester students, which are 2.53% : 9.43%, 8.23% : 9.67%, and 0.95% : 1.83%.
      Examples of lexicalized filled pauses:
   C:  Well, since I use motorcycle, I can just slip the cars, but it's kind of be dangerous, you know.
In these utterances, C three lexicalized filled pauses, that is well, kind of, and you know. C used these fillers when talking his experience riding motorcycle in traffic jam caused by Petra Square Apartment's 24 hour construction work. These lexicalized filled pauses are easily identified because they do not change the meaning of the content if they are deleted.
      After deciding fillers and their types, we can see Table 4.1 to see the frequencies. From the total number of each type of fillers, the most popular type of fillers used by the first semester students is ee (unlexicalized filled pause), followed by ehm (unlexicalized filled pause) in the second position and unit (.) (silent pause) in the third position, while for the seventh semester students, the most popular type of fillers used is ee (unlexicalized filled pause), followed by unit (.) (silent pause) in the second position, and yeah (lexicalized filled pause) in the third position. Ee is the most frequently used type of fillers by both the first and the seventh semester students.
4.1.2 Â Â Findings on the Functions of Fillers Used by the First and the Seventh Semester Students
This part will answer the second research question, which is the functions of fillers used by the first and the seventh semester students, and the differences and/or the similarities of those functions of fillers between the first and the seventh semester students. The details of the findings and its frequencies are shown in the table below:
