In order to strengthen the protection of Balinese traditional cultural expressions based on inventory at the National Data Center for Communal Intellectual Property, this study aims to investigate the arrangements of communal intellectual property protection in international flora and in Indonesia as well as the significant role of cooperation between the government and academician. This study employs analytical, conceptual, and normative legal research methods with statutes. The study's findings demonstrate that one kind of communal intellectual property is traditional cultural expressions. According to WIPO/GRTKF/IC/40/19, traditional cultural expressions are used to produce inventive and creative goods, and their protection can benefit both users and custodians while maintaining a balance between rights and obligations. Meanwhile, from the national context in Indonesia, Traditional Cultural Expressions are protected under Article 38 of Law No. 28 of 2014 on Copyrights where the state is considered the copyright holder. Traditional Cultural Expressions works have the potential to be developed as creative products in tourism activities. Therefore, inventory activity as an obligation of the government must be implemented by the government followed by a registration process to strengthen the protection of such Traditional Cultural Expressions. Inventory activity is significant to be implemented, primarily to protect Communal Intellectual Property ownership and prevent its use by parties outside the custodian who use it for commercial purposes without asking for permission. Strengthening the protection, and improving the inventory activity as well as its recording mechanisms are relevant to be implemented through intensive collaboration between the government and the academician.
