The development of information technology has encouraged the formation of a growing digital economy ecosystem in Indonesia. Various economic activities, such as e-commerce, digital financial services, and the use of internet-based applications, are highly dependent on the use of consumers' personal data. Personal data not only serves as user identity in digital systems, but also has strategic value for companies in understanding consumer behavior and developing more effective services. However, the use of personal data in digital economic activities also poses various risks, particularly related to data leaks and misuse that can harm consumers and reduce public trust in digital services. This study aims to examine the effectiveness of consumer personal data protection in the development of the digital economy in Indonesia. The focus of this study is on the effectiveness of consumer personal data protection in relation to Indonesia's digital economy. Data privacy is fundamental to the implementation of digital economic activities; however, its use must be protected by an adequate legal system. The enactment of Law No. 27 of 2022 on Personal Data Protection is one of the government's commitments to ensuring the protection of its citizens' personal data. Personal data protection still faces various challenges, such as rapid technological developments, potential data leaks, and low public awareness of the importance of personal data protection. Therefore, there must be better personal data protection through the implementation of digital literacy, control, and security standards. This system will provide adequate protection for consumers' personal data while also boosting the digital economy in this country.
