Abstract

Wilayah Darmo Kali merupakan salah satu kawasan penting di Kota Surabaya yang menjadi salah satu akses menuju Surabaya Pusat. Saluran drainase pada sistem ini cukup terawat dan memiliki dimensi yang relatif besar. Sistem drainase ini juga dilengkapi dengan dua rumah pompa, yaitu Rumah Pompa Darmo Kali dan Rumah Pompa Gunung Sari I. Rumah Pompa Gunung Sari I berfungsi untuk memompa debit air dari saluran menuju Kali Surabaya, sedangkan Rumah Pompa Darmo Kali memompa debit air dari saluran menuju Kali Mas. Sistem drainase Darmo Kali juga dilengkapi dengan dua pintu air yang berfungsi membagi debit air untuk masing-masing rumah pompa serta satu pintu air untuk mengalirkan debit air dari kawasan Mayjen Sungkono menuju sistem drainase Darmo Kali. Ketiga pintu air tersebut dioperasikan sesuai dengan kebutuhan. Namun, pada musim penghujan, genangan masih sering terjadi di beberapa lokasi, antara lain Jalan Ciliwung, Jalan Kutei, Jalan Indragiri, Jalan Hayam Wuruk, serta beberapa kawasan permukiman di sekitar saluran sekunder Ciliwung, Jalan Jambi, dan Jalan Opak. Berdasarkan kondisi tersebut, kawasan Darmo Kali yang memiliki daerah tangkapan air sekitar 2,6 km², saluran sekunder dan primer berdimensi relatif besar, serta didukung oleh dua rumah pompa, ternyata masih mengalami genangan di beberapa lokasi. Oleh karena itu, perlu dilakukan evaluasi terhadap kemampuan sistem drainase tersebut dalam menampung debit air hujan serta mengidentifikasi penyebab terjadinya genangan. Analisis permasalahan dalam Tugas Akhir ini diharapkan dapat mengetahui kemampuan sistem drainase Darmo Kali dalam menampung debit banjir periode ulang 2 dan 5 tahun serta mengidentifikasi penyebab terjadinya genangan. Berdasarkan hasil analisis, diketahui bahwa sistem drainase tersebut masih mampu menampung debit banjir periode ulang 2 dan 5 tahun. Genangan yang terjadi disebabkan oleh luapan air dari saluran Gunung Sari. Tugas Akhir ini secara khusus hanya menghitung volume air yang meluap dari saluran Gunung Sari.

The Darmo Kali area is one of the important areas in Surabaya and serves as one of the access routes to Central Surabaya. The drainage channels in this system are relatively well maintained and have comparatively large dimensions. The system is also equipped with two pumping stations: the Darmo Kali Pumping Station and the Gunung Sari I Pumping Station. The Gunung Sari I Pumping Station pumps water from the drainage channels into the Surabaya River, while the Darmo Kali Pumping Station pumps water into the Kali Mas River. The Darmo Kali drainage system is also equipped with two sluice gates that distribute water flow to the respective pumping stations and one additional gate that channels water from the Mayjen Sungkono area into the Darmo Kali drainage system. These three gates are operated according to prevailing requirements. However, flooding and waterlogging still frequently occur during the rainy season in several locations, including Ciliwung, Kutei, Indragiri, and Hayam Wuruk Streets, as well as residential areas around the Ciliwung secondary channel, Jambi Street, and Opak Street. Despite having a catchment area of approximately 2.6 km², relatively large primary and secondary drainage channels, and two pumping stations, the Darmo Kali area continues to experience waterlogging in several locations. Therefore, the capacity of the drainage system to accommodate rainfall runoff needs to be reassessed, and the causes of waterlogging must be identified. This Final Project aims to evaluate the capacity of the Darmo Kali drainage system to accommodate flood discharges with 2-year and 5-year return periods and to identify the causes of recurring waterlogging. The analysis indicates that the drainage system can still accommodate flood discharges with both return periods. The waterlogging is caused by overflow from the Gunung Sari channel. This Final Project specifically focuses on calculating the volume of water overflowing from the Gunung Sari channel.
