Article 2 Letter C of Government Regulation Number 5 of 2021 concerning the Implementation of Risk-Based Business Licensing states that business actors carry out risk-based business licensing independently. However, in practice, the person appearing often gives power of attorney to the Notary to carry out OSS registration. This can cause uncertainty regarding legal responsibility, considering that the Notary has no legal obligation to take care of the business license registration.

The purpose of this study is to analyze the implementation of the registration of a Limited Liability Company business license through the Online Single Submission Risk Based Approach (OSS RBA), which involves the role of a notary based on a power of attorney agreement, and to analyze the obstacles in the implementation of the registration of a limited liability company business license through the Online Single Submission Risk Based Approach (OSS RBA) by a notary based on a power of attorney agreement.

The method used in this study is the empirical legal method. The author used primary data in interviews with notaries in Banda Aceh City, the Capital Investment and One-Stop Integrated Service Office (DPMPTSP) of Banda Aceh City, and related parties. At the same time, Secondary data was obtained from primary legal materials by examining theories, concepts, legal principles, and laws and regulations related to this study.

The research results show that the business licensing process can now be done online through the Online Single Submission (OSS) system, integrated with the One-Stop Integrated Service (PTSP). Business actors apply for a permit through OSS, and the data will be stored in a centralized system. However, OSS still needs to overcome various technical obstacles, especially for notaries who often experience errors when inputting data. Generic error notifications make it difficult to identify problems, forcing users to repeat the process from the beginning. Slow data synchronization between OSS and other agency systems, such as AHU and taxation, complicates the licensing process.
