Objective: To look for a shift in presidential power from the development of the constitution and constitutional practices in Indonesia. After the amendments to the 1945 Constitution were made, there was almost no authority the President could exercise alone without seeking approval or consideration from other institutions, except for the appointment of ministers. The research aims to determine the factors that cause the President's Prerogative Powers to be inconsistent with the ideal conception of the Indonesian constitutional system. Since the beginning of Indonesian independence, the constitution has placed the prerogative rights of the president very dominantly, now after very fundamental changes to the constitution it also has implications for shifting the prerogative power of the president. Method: The research used juridical-normative. The approaches used in this research are the Legislative Approach, Conceptual Approach, and Historical Approach. Results: In a presidential system, the president has absolute authority in appointing ministers, although in practice the president is also closely tied to supporting parties or other parties who have made political commitments to the president. In the 1945 Constitution after the amendment, there is no longer anything that is truly a prerogative power of the president that can be exercised without obtaining approval or consideration, especially from the People's Representative Council as the people's representative institution. Conclusion: Prerogative power also has an undemocratic and potentially dangerous tendency, so to increase public accountability, the use of prerogative power by the President must apply power by involving institutions as representatives of the people.
