The Cipunagara River Basin is a component of the Citarum Watershed, necessitating a thorough analysis of hydrological data particularly rainfall and discharge for effective management. The watershed spans a moderate area of 1,363 km2 across three administrative divisions: Subang Regency, Indramayu Regency, and a segment of Sumedang Regency. Hydrological data analysis is imperative in watershed management. This study aims to analyze the key hydrological elements relevant to Cipunagara Watershed management. Rigorous consistency and homogeneity tests were conducted on rainfall data from each station. Changes in watershed flow patterns were scrutinized by examining shifts in runoff coefficient values and base flow magnitudes. The upward trend in runoff during the rainy season and the corresponding decline in base flow throughout the dry season may be attributed to land use alterations within the Cipunagara Watershed zone. To proactively address drought concerns in watershed management, the study calculated the 80% dependable flow to assess water availability during arid months, yielding an 80% dependable flow rate of 16.25 m3/s for the Cipunagara Watershed.

“…Debit muatan sedimen (Qs) dapat dipengaruhi oleh beberapa faktor yaitu curah hujan, durasi hujan, dan debit aliran air yang masuk ke telaga. Curah hujan yang tinggi dapat menghasilkan debit aliran besar (Sutrisno et al, 2020). Debit ini akan berkaitan dengan muatan sedimen melayang yang terangkut masuk ke telaga.…”

Telaga Jambeanom adalah salah satu telaga yang berada di Kalurahan Karangasem, Kapanewon Paliyan. Telagaini masih digunakan untuk sumber air di daerah tersebut untuk mencuci, mandi, dan lainnya. Telaga ini terbentuksecara alami dan dikelilingi oleh lereng dan bukit yang digunakan untuk bercocok tanam sehinggamemungkinkan ketika turun hujan sedimen akan terbawa masuk ke telaga. Penelitian ini bertujuan untukmengetahui seberapa besar sedimen melayang yang masuk ke telaga ketika ada aliran masuk ke telaga. Metodeyang digunakan dengan melakukan pengukuran debit aliran saat hujan dengan rentang waktu penelitian mulaidari 10 Maret – 24 April 2021 dan mengambil sampel aliran air, kemudian dianalisis secara matematis. Hasilyang didapatkan adalah Q1 dengan curah hujan 26 mm memiliki Qs puncak sebesar 0,00191615 mg.m3/L.s.Sedangkan Q2 dengan curah hujan 42 mm memiliki Qs puncak 0,01456176 mg.m3/L.s. Sedimen melayang yangmasuk menyebabkan air menjadi keruh ketika digunakan oleh masyarakat dengan kekeruhan sebesar 31,14-67,7NTU, sehingga mempengaruhi penggunaan air tersebut.Kata Kunci: Curah Hujan; Sedimen Melayang; Transport

Floods are the most common natural disasters in Indonesia and have enormous potential. This study aims to determine the flood hazard zone and regional arrangement in the Tarusan Watershed, South Pesisir Regency. To determine the flood hazard zone using the GIS approach. The indicators used to determine flood hazard are slope, rainfall, soil type, landform, geology, and land use. Determine the direction of regional arrangement with an Interpretative Structural Modeling (ISM) approach. The results showed that the high flood hazard zone in the Tarusan watershed is about 22% of the total area, the medium index is around 58%, and the low flood hazard index is 20%. The high - hazard zone of flood disasters in the study area is caused by high rainfall and topographic conditions of the Tarusan Watershed. The main priority in the management of flood - hazard areas in the Tarusan Watershed is to find economic alternatives to reduce forest destruction. Increasing the economic value of the community can lead to reduced community activities in carrying out land conversion, especially in forest areas.
