Development results instrument, consisting of 16 items with each of them has four multilevel score scores. Based on the results of the validity of the items at the stage of limited empirical test and extensive trial, all items were also declared valid, with a score above the rxy table value (0.34). The instrument also shows a high level of reliability with a r11 value of 0.75, from the extensive testing phase. Means that the instrument developed has fulfilled standard instrument standards.
