Abstract

Endikat Bengkok irrigation area is located in Muara Enim with an area of 1,140 ha. The Endikat Bengkok Irrigation channel used to irrigate rice fields in four villages, namely Segamit, Siring Agung, Arimantai and Fajar Bulan, districts of Semendo Barat Ulu. The source of irrigation water is available in the Endikat Bengkok River, which is a subsidiary of the Lematang River. The purpose of this study was to analyze the water availability in the Endikat Bengkok River for the adequacy of the Endikat Bengkok Irrigation Area, and the appropriate water provision group. Primary data was collected in the form of the planting group, secondary data in the form of rainfall data and climatological data. The calculation of evapotranspiration used the Penman method and the calculation of water availability used the F.J. Mock. From the calculation of water availability, it is shown that the maximum value occurred in April amounted to 48.15 m3 / s and the minimum value occurred in October amounted to 2.23 m3 / s. The availability of water for irrigation (80% dependable flow) is not sufficient to irrigate the entire Endikat Bengkok Irrigation Area. The most suitable water supply group by rotating based on the provisions of the irrigation planning criteria.

Abstract

Palembang is famous for the Musi River with a length of 460 km. The area along the river border is vulnerable to the impact of floods, this is the same thing that occurs in the Gandus District, which is mostly located on the banks of the Musi River. Analysis of the flood water level profile along the banks of the Musi River, which is affected by the tides is needed to find out how big the impact of flooding in the study area is. It aims to determine the type of tide, the amount of flow discharge, and simulation of river water level. Primary data was taken using a current meter to determine the speed of river flow. Some of the secondary data needed are river channel topographic data, rainfall data for 10 years, channel cross-section data and Musi River level data. The analysis was carried out in the form of a simulation of flood water level with the help of the HEC-RAS 5.0.7 program. The tidal type of the Musi River is based on the results of the study in the form of Diurnal Tide, with a watershed area of 2.2 km2 in Gandus District, the runoff discharge is 280.34 m3/s. The simulation results with the help of the HEC-RAS program obtained an average runoff height on the Musi River border of 2.7 m. The high runoff from the simulation can have a negative impact on the surrounding community, so there needs to be serious handling for flood control.
