Respondents of this study are experts who are appointed according to the expertise and experience in the implementation of WBL, particularly in polytechnic. The result of the analysis found that 31 elements in line with the FDM condition, which is the threshold value (d) surpass 0.2, group consensus among experts surpassing 75% and Fuzzy Score (A) exceeds 0.5. It indicates that all the experts had reached a strong consensus. Meanwhile, there are 4 elements were dropped due to did not meet the fuzzy score requirements.
