The export of marine sand from Indonesia to Singapore has been a controversial issue for decades, involving economic, environmental, and political interests. This study examines Indonesia's marine sand export policy, especially after the issuance of Government Regulation Number 26 of 2023, which reopened export permits after more than 20 years of prohibition. This policy aims to manage marine sedimentation to prevent disruption to ecosystems and shipping and meet domestic reclamation needs. However, there are many pros and cons that arise. On the one hand, this policy is expected to increase state revenue and open up employment opportunities. On the other hand , sea sand mining activities can cause serious environmental damage. This study uses qualitative methods with literature analysis to understand the impact of the policy. The results show that this policy provides more short-term benefits to the government and business actors, but poses long-term threats to the environment and society. Unsupervised marine sand mining has the potential to damage marine ecosystems, reduce fishermen's productivity, and threaten the sustainability of Indonesia's coastal areas. Therefore, more effective supervision and implementation of policies regarding this activity is needed.
