Reliability Reliability refers to the level of reliability of something. According to Arikunto 2013: 221, reliability refers to an understanding that an instrument reliable to be used at collect data has been good. Instruments that have been reliably will produce reliable data. Questionnaire in this study demonstrated the reliability using Cronbach Alpha formula as follows: r 11 = 1 − ∑ ь² ² t Descriptions: r 11 = instrument reliability k = number of items ∑ ь² = variety of questions ² t = variety of total variance Source: Arikunto, 2013: 239 Research instrument has high reliability if the coefficient Alpha ≥ 0,60. Results of the formula are classified with the following scale: Table 8. Reliability Scale Scale Category 0,00 – 0,199 Very Poor 0,20 – 0,399 Poor 0,40 – 0,599 Enough 0,60 – 0,799 High 0,80 – 1,000 Very High Source: Sugiyono, 2016: 242 Based on data processing result of this research, instrument reliability testing of student questionnaire show the score 0.764 r table 0.339, meanwhile instrument reliability testing of teacher questionnaire show the score 0.822 r table 0.754 . 62 According to Arikunto in Lestari 2012:22, research instrument has strong reliability if the value Cronbach’s Alpha ≥ 0,60. This result show that instruments are reliable and has high reliability.

H. Data Analysis Technique

In quantitative research, data analysis is an activity after data from all respondents, or other sources of data collected Sugiyono, 2015: 207. Data analysis techniques used in this research is to examine all the data obtained through questionnaires, observation, and documentation. Data obtained in the form of quantitative and qualitative data. Quantitative data obtained from the questionnaire instrument, while the qualitative data obtained from the documentation and observation. The data then compared to a predetermined standard. Collection data as input evaluations, processes and results are compared with the objective standards set by Ministry of Education and Cultural. After that, researcher assessed the data descriptions compare with the standards for decision making. The decision describes how the implementation runs. Furthermore, a decision will be converted into a percentage and described in the form of a sentence as follows: = 100 Source: Arikunto, 2013:251
