Abstract

Banjir merupakan kondisi permasalahan yang nyaris di tiap wilayah di Indonesia menghadapi bencana banjir tiap masa penghujan. Biasanya pemicu utama banjir merupakan kehancuran ekosistem area di wilayah aliran sungai. Keseriusan hujan yang meningkat besar menimbulkan banjir. Sungai Logawa yang terletak di Kabupaten Banyumas, mempunyai Luas DAS Logawa 29,54 Ha dengan panjang sungai 25 Kilometer. Sungai Logawa merupakan sebuah sungai di jawa tengah dan serta salah satu anak sungai Sungai Serayu yang terdapat di daerah Kabupaten Banyumas. Sebagian Usaha pemerintahan buat tingkatkan kenyamanan wilayah supaya terbebas dari sesuatu bencana tanah longsor serta banjir telah banyak di jalani antara lain 2 tata cara dalam pengendalian banjir di sungai dengan adanya dua tata cara struktur serta non-struktur dan struktural. Untuk menghitung curah hujan maksimum rata - rata menggunakan metode Poligon Thiessen dengan dua stasiun hujan yang mempengaruhi yaitu Kranji dan Rempoah. Data curah hujan yang dipakai dari tahun 2011 s/d 2022, sedangkan untuk debit banjir rencana diambil dari hasil perhitungan metode HSS Nakayasu dengan periode ulang 25 tahun sebesar 116.28 m3 /dt Setelah itu, kapasitas sungai diukur menggunakan perangkat HEC-RAS. Perbandingan kapasitas air dan estimasi debit banjir dilakukan untuk mengidentifikasi genangan banjir di Sungai Logawa. Penanganan menggunakan konsep pengendalian banjir dengan berwawasan lingkungan, dengan prioritas pada normalisasi sungai dan perkuatan tebing menggunakan bronjong dan Bangunan pengendali banjir yang akan menggunakan bahan lokal dan tenaga kerja setempat.

Flood is a prevalent issue across almost every region in Indonesia, encountering flood disasters during the rainy season. The primary cause of floods is typically the destruction of ecosystem areas within river basins. The increasing severity of rainfall greatly contributes to flooding. Logawa River, situated in Banyumas Regency, has a Logawa River Basin area of 29.54 hectares with a river length of 25 kilometers. Logawa River is a river in Central Java and one of the tributaries of Serayu River located in Banyumas Regency. Various government efforts have been made to improve the comfort of the area to prevent landslides and floods. Among these efforts are two flood control methods for rivers, including structural and non-structural approaches. The average maximum rainfall is calculated using the Thiessen Polygon method with two rainfall stations, namely Kranji and Rempoah, influencing it. Rainfall data used ranges from 2011 to 2022, while the planned flood discharge is determined from the calculation results of the HSS Nakayasu method with a 25-year recurrence interval, amounting to 116.28 m3/dt. Subsequently, river capacity is measured using HEC-RAS software. A comparison between water capacity and estimated flood discharge is conducted to identify flood inundation in Logawa River. Flood management employs an environmentally conscious flood control concept, with a priority on river normalization and embankment reinforcement using gabions and Flood control structures that will utilize local materials and local labor
