Abstract

Air Alas Dam in Seluma Regency is used as irrigation water drainage. In the Air Alas irrigation channel there have been many changes in conditions and buildings, especially in the primary channel. As well as the number of oil palm plantations around the irrigation area. Thus, it is necessary to analyze the efficiency and loss of water. The purpose of this study was to analyze the efficiency of the primary channel of the Air Alas Irrigation Area, analyze water loss due to evaporation and seepage, and efficiently evaluate the primary channel of the Air Alas Irrigation Area. The methodology used to calculate the efficiency and water loss are analyzed by the inflow and outflow methods. The data used in this analysis are flow velocity data with current meters and evaporation data from BMKG. From the results of the efficiency analysis that has been carried out, the smallest efficiency is found on the BA.Kr 7 channel worth 44.62%. Percentage of water loss of 19.85%, with the value of water loss due to the greatest evaporation occurs along the primary channel is in BA.Kr 4 which is 2.644 x 10-4 m3 / sec, and the value of water loss due to the biggest secretion is on the BA.Kr 1 channel with a value of 2.312 x 10-4 mm / day. The average efficiency of the primary channel is 80.15% this result is not in accordance with the theoretical efficiency determined by KP-01 which is ≥ 90%.
