Online Gender-Based Violence (OGBV) in Indonesia , as evidenced by this doctrinal legal study analyzes the gaps and potential synergies between Indonesian positive law and Islamic law employing a qualitative juridical- normative methodology with a socio-legal analytical framework, data were collected through content analysis of maqāṣid al-sharīʿah principles. Using a qualitative doctrinal legal methodology with a socio-legal analytical framework, the study conducted a content analysis of statutory regulations, including the Electronic Information and Transactions Law (UU ITE), the Criminal Code (KUHP), the Domestic Violence Elimination Law (UU PKDRT), the Sexual Violence Crime Law (UU TPKS), Islamic legal documents including the Indonesian Ulama Council (MUI) Fatwa No. 24 of 2017. The analysis reveals that current positive regulations are sectoral and predominantly punitive, lacking a comprehensive victim-centered approach, while Islamic fatwas remain ethically normative but operationally non-integrated into public policy. The research identifies ḥifẓ al-ʿaql (protection of intellect) as robust normative foundations within maqāṣid al-sharīʿah that remain underutilized in policy formulation. Consequently, the study concludes that transformative regulatory integration is urgently required to bridge the gap between state enforcement and religious legitimacy, thereby strengthening the protection of women's rights in the digital sphere and advancing the objectives of Sustainable Development Goal 5 on gender equality.
