The decision to develop the Archipelago Capital (IKN) as the capital city of Indonesia is one of the state political decisions that has a big vision towards a Golden Indonesia 2045. As a project with a large and complex budget, its financial management must be carried out in an accountable manner, free from corrupt practices, and supported with a strict monitoring system so that it can run by prioritizing the principles of good governance. Therefore, IKN development policies and regulations must be in line with these principles and objectives. This study aims to describe the current condition of IKN development related to the potential for corruption, opportunities, and obstacles in preventing it. So, this study can produce policy recommendations that can be implemented in the implementation of IKN development. The legal research method used in writing this thesis is a normative juridical research method, with a statutory approach. The research uses qualitative analysis using primary and secondary legal data/material sources. Data/legal material processing activities begin with collection, analysis, and presentation, then formulated and presented systematically and descriptively according to the respective subject matter. The results of the study show the potential for corruption in the institutional aspects of the IKN Authority which are still weak in supervision, financing schemes that are vulnerable to conflicts of interest, and the implementation of IKN development where the procurement of goods still has the potential to give rise to bribery and conflicts of interest. This makes the development of IKN not in line with the principles of good governance. So, to prevent potential corruption in IKN development, better prevention optimization is needed in these three aspects, both in the preparation of clauses in regulations and the formation of institutions. It is hoped that this will enable the IKN project to run efficiently, effectively, and without corrupt practices occurring.
