This research aims to analyze the protection of local community rights and regulatory harmonization in the management of Mandalika Special Economic Zone, regarding regulations that do not give adequate legal protection to local communities, the dispute that has arisen, and the benefits derived from the management of KEK Mandalika . The basis of this research is the protection of local community rights and the benefits derived from the management of the zone that also holds the status of Management Rights (HPL) as well as the National Strategic Project (PSN) in KEK Mandalika . This research employs an empirical legal method by collecting field data and using qualitative analysis. This research finds the fact that KEK Mandalika Management is more oriented towards investment interests and tends to weaken community rights. Regulations related to the KEK, HPL, and PSN do not strongly accommodate community protection and are more investment oriented, with only a limited number of provisions favoring the community, thereby failing to fully reflect the mandate of Article 33 paragraph (3) of the 1945 Constitution of the Republic of Indonesia. Therefore, harmonization among these regulations is necessary in order to provide stronger legal protection and greater public benefit. Therefore, there shall be regulatory harmonization among these regulations to give strong protection and provide greater public benefit.
