Abstract—Auditor is a profession that is highly regulated. One of the regulations that guides the internal auditor profession is the internal audit professional standard. In the public domain, the Association of Indonesian Government Internal Auditors has compiled the preparation of Government Internal Audit Professional Practices and Indonesian Government Internal Audit Standards. The Public Service Agency places itself in a unique position as a state-owned institution that manages the nation's indivisible assets. BLU manages APBN funds as well as recruits professionals who have specific expertise in their fields. The purpose of writing this paper is [1] to obtain information on what the actual position of the SPI profession is at BLU in terms of changing the framework and standards used as work guidelines in the implementation of internal audits; [2] To obtain information on the implementation of audit standard applications in Public Service Agencies and what are the obstacles in terms of its implementation, and [3] To obtain information on how best to apply standard audits in Public Service Agencies. The results of the study show that in the personal aspect, a standard is able to provide guidance on how to act or behave in everyday life, while in the professional aspect, a standard is a mandatory component that must be used by professionals in carrying out their practice. In the private sphere, internal auditing standards have been formulated by the IIA. One part of the IPPF is the Internal Auditor Professional Standards. This standard is an important and essential part in realizing the role and performance of internal auditors both individually as professionals and by the internal audit unit as an organ within the company. In the public domain, the Association of Indonesian Government Internal Auditors has compiled the preparation of Government Internal Audit Professional Practices (KP3IP) and Indonesian Government Internal Audit Standards. SAIPI must be applied by APIP leaders and Auditors in all internal control activities, including audit activities as referred to in article 53 of Government Regulation number 60 of 2008. BLU is an institution engaged in the public sector (APBN funding and state financial accountability) but also engaged in private sector (business process). The 'hybrid' mechanism places the internal oversight unit in a unique position. On the one hand, BLU auditors must function as a guarantee to examine aspects of internal control over the use of state finance, but on the other hand, many BLU auditors are not civil servants (Non PNS). Currently there is no confirmation or standard setting that must be adhered to by institutions such as public service agencies. Another aspect that becomes capital in the status of BLU auditors is confirmation whether they are APIP or outside the division as APIP. Auditing standards will protect the auditor as well as the institution (client) being audited. The presumption that the internal auditor is not optimal with the many conditions or findings of the external auditor can actually be overcome by having audit standards. Auditing standards will protect internal auditors if cases occur in internal institutions, both irregularities and fraud. Internal audit standards comprehensively guide internal auditors in carrying out their functions for both the insurance function and the consulting function.
