ABSTRACT The purpose of this study was to determine the effect of ethical idealism, ethical relativism, and professional commitment of auditors on the interest of public accountants to do whistleblowing. Primary data was obtained through a closed questionnaire which was distributed to auditors working at KAP in Palembang City. The sample was taken using a saturated sampling technique, namely where the entire population was sampled, the sample was obtained as many as 39 respondents. The results of multiple linear regression analysis partially prove that the ethical idealism variable affects the interest in doing whistleblowing with a t-count of 4,569 with a significance level of 0.000. While the ethical relativism and professional commitment variables have no significant effect on the interest in doing whistleblowing, with t-count results of 0.012 with a significance level of 0.991 and 1.131 with a significance level of 0.286, respectively. The results of data analysis show that the F-count of 11,596 is greater than the F table of 2.98, which indicates that this research model is feasible to use in predicting the value of auditors' interest in whistleblowing. Keywords: Idealism Ethics, Relativism Ethics, Professional Commitment, Interest in Doing Whistleblowing.
