The rapid development of digital technology has increased children's engagement with the digital environment while expanding risks related to privacy, personal data protection, exposure to harmful content, and exploitation through digital platforms. In response to these challenges, the Indonesian Government enacted Government Regulation Number 17 of 2025 concerning the Governance of Electronic System Implementation for Child Protection and the Regulation of the Ministry of Communication and Digital Number 9 of 2026 to strengthen the legal responsibilities of electronic system providers in protecting children in the digital environment. This study aims to analyze the legal protection of children in the digital environment following the implementation of Government Regulation Number 17 of 2025 and the Regulation of the Ministry of Communication and Digital Number 9 of 2026 and to assess their conformity with the evolving principles of children's rights in the digital environment. The study employed normative legal research using statutory, conceptual, and comparative approaches through library research on legislation, scholarly literature, and relevant policy documents. The findings indicate that both regulations have shifted the child protection paradigm from a content-control approach to digital platform governance by assigning electronic system providers primary responsibility for child protection through age verification, personal data protection, risk management, and child-friendly service design. The study also demonstrates that Indonesia's regulatory direction is consistent with international principles on children's rights in the digital environment, although implementation continues to face challenges related to the effectiveness of age verification, supervisory capacity, and consistent regulatory enforcement. The study concludes that Government Regulation Number 17 of 2025 and the Regulation of the Ministry of Communication and Digital Number 9 of 2026 have established a more comprehensive legal framework for protecting children in the digital environment, while successful implementation depends on stronger oversight, greater compliance by electronic system providers, and continuous policy evaluation.
