T The relocation of the national capital (ikn) from jakarta to nusantara is a strategic move by indonesia to achieve equitable development and create a smart, sustainable, and environmentally conscious city. the relocation of the ikn is driven by various issues in jakarta, such as overpopulation and natural disasters. additionally, the ikn is expected to become a new economic growth center in central indonesia. however, the relocation of the ikn also raises several legal and constitutional issues. the biomimicry approach offers an innovative solution in the design of buildings in the ikn by emulating natural principles, with the aim of making the mpr legislative building efficient, effective, and environmentally friendly. sustainability is also a key focus in the design, aiming to create a built environment that harmonizes with nature in line with the ikn vision. this is expected to serve as a reference for completing the final thesis on the application of biomimicry architecture and sustainable concepts in the design of the mpr building in the ikn, as well as realizing the creation of an iconic, innovative, and environmentally conscious mpr building with the title “design of the mpr building using a biomimicry approach in the national capital city (ikn).”
