The Efficiency of Rawa Mayo Irrigation Channels in Kurik Sub-Distrik, Merauke

The purpose of this research is to know the efficiency of irrigation networks and water loss Swamps the Mayo that occurred during the distribution of irrigation. Research methods used in this research is a research field that is by calculating the discharge of water channels, perkolasi, evaporation and seepage. The research results obtained average discharge early in the primary channel of 0.292 m3/s, the final discharge 0.25 m3/s, the loss of water, 0,042 m3/s and the efficiency of irrigation of 85,62%. On the secondary channel 1 average early discharge 0.268 m3/s discharge, 0.153 m3/s end, water loss of 0.115 m3/s and irrigation efficiency of 57,08%. On the secondary channel II early 0.22 m3/s debit, debit end 0.118 m3/s, water loss of 0.102 m3/s and irrigation efficiency of 53,63%. Irrigation efficiency at Mayo swamp irrigation is 46.39% where the value still meets the KP-01 (2013) Irrigation planning standard.
