F. Trustworthiness of Data and Analysis

According to Moleong 2007: 321 - 342, there are four criteria as the basis to achieve trustworthiness of the research in a qualitative research. They are credibility, transferability, dependability and conformability. In additional, Maleong proposes ten techniques in achieving trustworthiness of the data. They are 1 extended participation, 2 perseverance observation, 3 triangulation, 4 discussion, 5 reference sufficiency, 6 analysis of negative case, 7 m ember’s checking, 8 thick description, 9 auditing, and 10 confirm-ability auditing. Some techniques above are used in this research in order to verify the trustworthiness of the data analysis. The credibility of this research is checked by using triangulation technique, perseverance observation and discussion with colleagues. The triangulation technique is done by involving other researchers who the same research subjected in the field to interpret the data. They verify the data with their analysis of thematic variation. The results are, then, discussed
