This study discusses the effectiveness of implementing administrative sanctions to overcome fraud practices by health facilities against National Health Insurance (JKN) participants in Indonesia. Fraud practices involving claim manipulation, bill inflation, and falsification of diagnoses result in losses for JKN participants and reduce the quality of health services. This study identifies challenges in supervision, regulatory weaknesses, and obstacles in law enforcement that affect the effectiveness of the administrative sanctions imposed. Based on the analysis, this study recommends regulatory reforms that include the implementation of stricter sanctions, strengthening supervision with information technology, and increasing outreach programs to raise awareness of the impacts of fraud. It is expected that with this reform, the JKN system can run more effectively and reduce fraud practices that are detrimental to all parties.

The discontinuity of regulations concerning health workers in health law legislation poses a challenge for the application of the principle of legal certainty in Indonesia. The principle of legal certainty is an essential foundation in the legal system that guarantees the rights and obligations of health workers and the community. However, there is a gap between the regulations for health workers and the principle of legal certainty, which impacts the clarity of the legal status, rights, and obligations of health workers. This research aims to examine the discontinuity between health workers' laws and the application of the principle of legal certainty, as well as the impact arising from this inconsistency. Additionally, this research identifies efforts that can be made to align labor regulation and health worker regulations with the principle of legal certainty. Using normative legal research methods through legislative and conceptual approaches, this study finds that regulatory harmonization is necessary to strengthen legal certainty in health worker regulation in Indonesia.
