Kajian Koefisien Rembesan pada Saluran Irigasi Tersier di Desa Suka Maju Daerah Irigasi Medan Krio Kecamatan Sunggal kabupaten Deli Serdang

Abstract

ARMIN: Seepage Coefficient Study On Tertiary Irrigation Channels In the village Suka Maju Regional Irrigation District of Sunggal Krio Medan Deli Serdang, guided by Sumono and Nazif Ichwan. Water delivery systems to land in the village of Suka Maju done through tertiary channels which are land lines. It can megakibatkan the water loss through evapotranspiration, percolation and seepage that may affect the efficiency of water delivery. Of the three factors, the loss of water through seepage in the field more difficult. This study aims to assess the seepage coefficient on tertiary irrigation canal in the village, Suka Maju Regional Irrigation District of Sunggal Krio Medan Deli Serdang. From the research results obtained by the coefficient of seepage field on the right edge of the channel by 3775.68 mm / day, the left edge of the channel by 10368.8 mm / day. Efficiency drainage channel along the 30 m amounted to 91.02%.
