Analysis of variance, it was found that the most accurate model in predicting potential bankruptcy is Altman Z_score. Based on this model could be found, statistically significant that a group of sharia has a potential bankruptcy smaller than the non_sharia. Based on the third question, could be found that good corporate governance have positive and significant effect to potential bankcruptcy for the sharia companies, while the rate exchange of rupiah to US dollar has negative and significant effect to ones.
