Dadahup swamp irrigation area is included in the food estate project location. The government has rehabilitated irrigation networks to support the program in 2020. A good agricultural system should be supported by water availability to fulfill irrigation water needs. The obstacle often faced in agriculture is usually the water deficit that occurs in the dry season. Corn is usually cultivated in the dry season to reduce water irrigation demand and cannot be inundated with water for long. This study aims to determine the water availability in the irrigation channels to supply water needs for corn. The Storm Water Management Model is used to perform hydraulic analysis in irrigation channels. The results showed that the water levels ranged from +0.04 m to 0.49 m in irrigation channels, while the ground elevations ranged from +1.12 m to 1.74 m. Due to water levels in the irrigation channels below the ground elevation, the Blok A5 Kanan can be proposed for corn cultivation in the dry season. This study’s outcome will be increased crop productivity, achieving sustainable agriculture.

“…Based on the graph above, it shows that the operation and maintenance optimization of the Dadahup Lowland Irrigation Area in the dry season can reach pH level 3 and increase to level 5 in the rainy season. The increase in water quality, namely pH, can reach a level of 4.5 with the influence of rainfall and decreases to level 2 in the dry season (Zevri et al, 2022).…”

Dadahup lowland irrigation area is one of the areas developed as a food estate. Land cover change to shrubs is caused by channels with buildings that are not functioning optimally, so it is often hit by floods and droughts. One of the efforts to improve the function of channels and buildings is to control the minimum water level of 60 cm in the dry season and the maximum water level of 10 cm in the rainy season. This study aims to determine the optimal operations and maintenance through adjusting the elevation of the gate opening to achieve the quantity and quality for the development of water management systems in lowland irrigation. The research method was carried out with hydraulic simulation based on the tides of the Barito River Mouth, discharge, rainfall, and pH obtained from telemetry monitoring system with openings of all sluice gates in primary channels and secondary channels. The results showed that operation and maintenance optimization can be done by setting primary and secondary sluice gates that are opened at a water level elevation above + 0.5 m in the dry season as supply and water level elevation + 1.1 m in the rainy season as drainage. Primary and secondary sluice gates are closed at water levels below + 0.5 m to maintain water levels and water quality.Keywords optimization, lowland, Dadahup Lowland Irrigation Area , HEC-RAS, hydraulic ABSTRAKDaerah irigasi rawa Dadahup merupakan salah satu daerah yang dikembangkan sebagai lumbung pangan.

Salah satu upaya untuk meningkatkan fungsi saluran dan bangunan adalah dengan mengendalikan tinggi muka air minimum 60 cm pada musim kemarau dan tinggi muka air maksimum 10 cm pada musim hujan. Penelitian ini bertujuan untuk mengetahui pola operasi dan pemeliharaan yang optimum melalui pengaturan pintu dalam mencapai kuantitas dan kualitas air yang sesuai untuk pengembangan sistem tata air di lahan irigasi rawa. Metode penelitian dilakukan dengan simulasi hidraulika berdasarkan pasang surut muara Sungai Barito, debit, curah hujan, dan pH yang diperoleh dari sistem monitoring telemetri dengan bukaan setiap pintu air pada saluran primer serta saluran sekunder. Hasil penelitian menunjukkan bahwa optimasi operasi dan pemeliharaan dapat dilakukan dengan pengaturan pintu air primer dan sekunder yang dibuka pada elevasi muka air di atas + 0,5 m pada musim kemarau sebagai supply dan elevasi muka air + 1,1 m pada musim penghujan sebagai drainase. Pintu air primer dan sekunder ditutup pada elevasi muka air di bawah + 0,5 m untuk menjaga tinggi muka air dan kualitas air.Kata Kunci: optimasi, rawa, Daerah Irigasi Rawa Dadahup, HEC-RAS, hidrolika

The Katingan Swamp Irrigation Area, established in 1980, has an important role in supporting food security in Indonesia. It needs to be reclaimed to increase agricultural production, especially for leaching acid sulphate soil. The swamp irrigation area was expanded and rehabilitated so that the two-way flow became a one-way flow system to support the leaching process. This study aims to assess the discharge and water quality alterations in the Katingan main channel after the change of flow system. The aim is achieved by comparing the outcomes obtained from one-way and two-way flow simulations. The simulation used a mathematical model based on water level, water quality, and land topography data collected in the field. According to the findings, the two-way system demonstrates that fresh water from the river has not been able to improve water quality (pH) at the end of the primary channel, thereby leading to extreme acidity in those regions. Meanwhile, a one-way flow facilitates efficient circulation and delivers fresh water to the farthest service regions. Effective water circulation is important to enhance water quality in agricultural areas that have recently expanded. The current study focuses on mid-irrigation. Future research may cover the entire irrigation network for in-depth analysis.
