T This study compares the president’s authority in the ratification of bills in indonesia and the united states in order to identify similarities and differences as well as their relevance to strengthening indonesia’s constitutional system. the research employs a normative legal method with a comparative (descriptive–comparative) approach, based on secondary legal materials. the findings show that in both countries the president plays a role at the final stage of lawmaking; however, in indonesia the president acts as a partner of the house of representatives from the deliberation stage and does not possess post-approval veto power, as a bill remains valid even if it is not signed within 30 days. in contrast, in the united states the president exercises final control through the regular veto and the pocket veto, with the possibility of a congressional override in the case of a regular veto. this difference underscores distinct models of checks and balances: in the united states through the veto and override mechanism, and in indonesia through joint approval and judicial review by the constitutional court. in terms of relevance, to strengthen corrective control at the final stage of legislation on a partial basis limited to specific articles and/or paragraphs deemed contrary to national policy and urgency this study proposes the strengthening of a limited veto right for the president, the introduction of pre-enactment constitutional review, and improvements in the quality of the legislative drafting process.
