<![CDATA[The Jakarta Giant Sea Wall has primarily been debated as an instrument for coastal flood control and adaptation to sea-level rise. While this perspective remains important, it does not fully capture the strategic value of coastal infrastructure situated within an area that supports ports, logistics, energy, communications, transportation, public services, and governmental functions. This article aims to formulate a strategy for developing the Jakarta Giant Sea Wall as strategic civil infrastructure that supports maritime defense without leading to the militarization of the project. The study employs a qualitative approach through a narrative-conceptual literature review, synthesizing scholarship on the securitization of coastal defense, maritime critical infrastructure protection, infrastructure resilience, physical security against asymmetric threats, multi-agency command and control, and maritime cybersecurity. The analysis demonstrates that the defense value of the Giant Sea Wall lies not merely in its capacity to withstand hydrometeorological hazards, but also in its potential to become part of a layered protection architecture that safeguards the continuity of strategic functions, supports maritime situational awareness, strengthens inter-agency coordination, and enhances the resilience of digital control systems. This article develops a revised Integrated Maritime Defense Infrastructure Framework (IMDIF) consisting of five layers: the threat spectrum; physical and operational protection; continuity of critical functions; command, control, and information integration; and cyber and institutional resilience. The framework conceptualizes the Giant Sea Wall as dual-use strategic infrastructure whose primary function remains civilian, while its design, governance, and preparedness can provide additional value for maritime defense and the security of the Jakarta metropolitan area.]]>
