Abstract

Secara alami, hilir Sungai Hujan mengalami banjir dan kekeringan secara periodik. Proses ini bermanfaat bagi distribusi nutrisi dan mineral terlarut dari bantaran sungai menuju air sungai pada saat susut dan sebaliknya. Bendung Gerak pada umumnya dibangun untuk meminimalisir kejadian bencana, sebagaimana yang terjadi pada Bendung Gerak Sembayat di Sungai Bengawan Solo, Kabupaten Gresik dalam sepuluh tahun terakhir. Meskipun mampu mengendalikan banjir dan kekeringan, keberadaan bendung justru menambah permasalahan baru bagi ekosistem. Bendung yang membatasi proses alami banjir mengakibatkan ketidakseimbangan ekosistem sungai. Ketidakseimbangan ini berbahaya bagi ekosistem yang berdampak pada manusia yang bergantung pada sungai sebagai sumber air dan mata pencaharian. Dari permasalahan tersebut, maka diusulkan konsep perancangan “Sustainable Architectural Dam” melalui pertimbangan desain bentuk, fasad, estetika serta keseimbangan
ekosistem sungai dan manusia pada bendung. Konsep ini mengkolaborasikan prinsip ekologi arsitektur dan biomimicry arsitektur untuk menghasilkan desain bendung yang ramah bagi ekosistem sungai, termasuk manusia di dalamnya. Dalam mewujudkannya digunakan tools Ansys untuk mendeteksi pergerakan potensi angin dan Fusion untuk memaksimalkan struktur dengan metode shape optimization. Hasil desain yang didapatkan berupa re-desain bendung dengan memaksimalkan potensi hilir sungai sekaligus memperhatikan ekosistem hilir sungai melalui pendekatan arsitektur Re-desain yang didapatkan berupa gambaran konsep dan detail bangunan secara formal dan spasial.

Naturally, the downstream of the rain river experiences periodic floods and droughts. This process is beneficial for the distribution of dissolved nutrients and minerals from riverbanks to river water at the time of shrinkage and vice versa. Moving Dams are generally built to minimize disaster events, as happened to the Gerak Sembayat Dam on the Bengawan Solo River, Gresik Regency in the last ten years. Even though they can control floods and droughts, the existence of dams adds new problems to the ecosystem. Dams that limit the natural process of flooding result in an imbalance in the river ecosystem. This imbalance is harmful to ecosystems impacting humans who depend on rivers for water sources and livelihoods. From these problems, the proposed design concept of "Sustainable Architectural Dam" through consideration of the design of the shape, facade, aesthetics, and the balance of the river ecosystem and humans on the bend. This concept collaborates the principles of architectural ecology and architectural biomimicry to produce a dam design that is friendly to the river ecosystem, including humans in it. In making it happen, Ansys tools are used to detect potential wind movement and Fusion is to maximize the structure with the shape optimization method. The design results obtained are in the form of a re-design of the dam by maximizing the potential of the downstream river while paying attention to the downstream ecosystem of the river through an architectural approach.
