Abstract

Berdasarkan latar belakang yang begitu kompleks dalam penyebab banjir di Jakarta, maka pemerintah mulai melakukan pembangunan dengan konsep Sustainable City melalui program penerapan Green Infrastruktur. Penerapan green infrastruktur yang berkonsep ecodrainage dalam sistem drainase di kawasan Kelapa Gading menjadi sebuah harapan terjadinya kemanfaatan secara holistik dari segi lingkungan. Penelitian ini bertujuan untuk mengetahui pengendalian banjir berbasis ecodrainage yang optimal di Kelapa Gading dan mengetahui manfaat keberlanjutan dalam penerapan green infrastructure dan mengetahui ke efektifannya hingga tahun 2030. Metode analisis penelitian ini menggunakan pendekatan sistem dinamik, yaitu merupakan metode permodelan dari suatu sistem yang dinamis dan kompleks dengan membentuk suatu skenario tertentu berdasarkan elemen-elemen yang saling berinterkasi dalam bentuk umpan balik atau Causal Loop Diagram. Dalam system dinamis ini permasalahan akan dilihat secara keseluruhan berdasarkan hubungan antar variabel yang saling memberikan pengaruh. Penyusunan model sistem dinamis akan dibantu menggunakan software Powersim Studio Version 10. Hasil penelitian ini telah mengungkapkan, berdasarkan model yang telah terbangun tersebut penggunaan ecodrainage memiliki manfaat dalam konservasi air tanah, penekanan laju penurunan tanah dan penekanan peningkatan laju banjir. Berlandaskan hasil simulasi antara penerapan skenario eksisting, moderat tahap I dan II, dan optimist, penerapan skenario moderat tahap II lah alternatif terbaik. Kebijakan strategis yang diterapkan yaitu kebijakan pembatasan penggunaan air tanah sebesar 5%, pembangunan ecodrainage sebanyak 3500 titik dan penggunaan infrastruktur polder di Kelapa Gading dengan kapasitas pompa 7 m3/s sebanyak 2 buah. Pada penelitian ini juga menggambarkan jumlah ecodrainage yang optimal tergantung dengan kondisi jenuh lapisan tanah. ******** Floods are a very common problem in this capital city. Extraction of groundwater that exceeds its recharge, the occurrence of land subsidence, poor drainage are the main factors causing flooding in this study. With such a complex background, Jakarta has begun to develop the concept of a Sustainable City through the implementation of the Green Infrastructure program. The application of green infrastructure with the concept of ecodrainage in the drainage system in the Kelapa Gading area is a hope for holistic benefits from an environmental perspective. This study aims to determine optimal ecodrainage-based flood control in Kelapa Gading and determine the benefits of sustainability in the application of green infrastructure and determine its effectiveness until 2030. The analytical method of this research uses a dynamic system approach, which is a modeling method of a dynamic and complex system. by forming a certain scenario based on elements that interact with each other in the form of feedback or Causal Loop Diagrams. In this dynamic system, the problem will be seen as a whole based on the relationship between variables that influence each other. The development of the dynamic system model will be assisted using Powersim Studio Version 10 software. The results of this study have revealed, based on the built model, the use of ecodrainage has benefits in groundwater conservation, suppression of land subsidence and suppression of increased flood rates. Based on the simulation results between the application of the existing scenario, moderate stages I and II, and optimism, the application of the moderate stage II scenario is the best alternative. The strategic policies implemented are the policy of limiting the use of ground water by 5%, the construction of 3500 ecodrainage points and the use of polder infrastructure in Kelapa Gading with a pump capacity of 7 m3/s as many as 2 units. This study also describes the optimal amount of ecodrainage depending on the saturated condition of the soil layer.
