Limited green space due to urbanization causes problems such as rising micro-temperatures, declining air quality, and increased surface runoff, which increases the risk of flooding. This condition is worsened by the dominance of gray infrastructure. In fact, these problems could be addressed by applying green infrastructure. An open space that can implement green infrastructure is a roundabout. This study aims to explore and optimize the GKU roundabout at ITERA as part of the city's green infrastructure. The research employs a qualitative-descriptive method and is divided into two stages: the pre-design and the design stage. The pre-design stage involves collecting both primary and secondary data necessary for designing the GKU roundabout. The design stage consists of three steps: site inventory, analysis, and design. During this stage, the software used includes AutoCad, SketchUp, and Adobe Photoshop. Green infrastructure that can be applied includes stormwater planters, rain gardens, and permeable concrete. These strategies can help absorb run-off water, prevent flooding, and filter pollutants from run-off water. The seating can also be designed with raised legs, thereby increasing the water infiltration areas. Furthermore, introducing a greater variety of plant species would not only enhance the site’s visual appeal but also promote biodiversity and strengthen its ecological value. The results of this research are expected to serve as a guideline for local authorities in designing a more sustainable campus landscape.
