Analysis Of Water Loss Efficiency Of Agricultural Harvest Reselts In Guakdale Irrigation Are Of Tuatuka Village, Kupang City, Province Of East Nusa Tenggara

Abstract

Agricultural development in Indonesia is still considered important from the overall development, especially to support the pace of the economy in general. Gaukdale Irrigation Area which has an area of 168.50 hectares of land located in the village of Tuatuka has the Gaukdale Irrigation Network that was built since the year 2000. The existence of damage from irrigation network infrastructure has resulted in water loss in the carrier channel, namely in the primary channel and secondary along with other completeness buildings, so that water entering the paddy field is not optimal. The percentage of damage to the BG-1 Primary Channels and BG-Ka Secondary Channels in the Guakdale Irrigation Network is = 8.39%. The influence of channel damage on Carrier Channels in the Guakdale Irrigation Network experienced water loss, namely in the Primary Channel of 1.12 m3 / sec and on the Secondary Channel of 0.69 m3 / sec.
