Form,Context,and Sourceof Data Instrument of the research

interpretation a set of text based on the researcher’s perspective. Each perspective on meaning caused different interpretation of a text. In this research, the researcher was the interpreter of selected text. The process of data analysis is stated in details as in the following: 1. transferring and classifying the data collected into the data sheet, 2. interpreting the data according to the context where this data was taken, 3. discussing the data with supervisor and colleagues who are linguistics students, and 4. making description of the data and drawing conclusion.

F. Trustworthiness

To validate the finding of this research, the researcher applied triangulation which is the combination of methodologies in the study of the same phenomena or programs Patton, 1980:108. To enhance the validity of the finding, Moleong2001:173 states that four categories of data trustworthiness such as credibility, dependability, conformability, and transferability. Those categories of data trustworthiness had to be applied to check and prove the data. Credibility and conformability were chosen to triangulate the data of this research. Credibility means that the result of the research was credible or believable from the perspective of the research participants. If the research is credible, then the conclusion of the research was supported by the findings. The researcherused a consistence and appropriate methodology as well as systematic and comprehensive literature reviewto enhance the credibility of the research. Meanwhile, conformability refers to the neutrality of the research interpretation to check how far the research could be confirmed by others. Thus, the finding and the data of the research should be interpreted based on the data. Peer debriefing technique by discussing the data with the people considered competent in criticizing the process of analysing the data was chosen by the researcher to triangulate the research. The researcher discussed the research with his supervisors, TitikSudartinah, S.S., M.A. and Susana Widyastuti, S.S., M.A., Ph.D. to avoid plagiarism. The researcher also asked other researchers to check and discuss about the research findings, so the validity of the data in this research could be accomplished by the researcher.
