Sistem Pemberian Air Sebagai Dasar Penyusunan Jadwal Rotasi Daerah Irigasi Kaiti Samo Di Kabupaten Rokan Hulu
Kaiti Samo irrigations area of Rokan Hulu Regency has an irrigated land area of 1,594 Ha. Availability of weir debris is decreasing and agricultural water needs are increase, so it is necessary to regulate the system of giving and regulating water optimally. Planting plan by increasing cropping intensity using two systems, such as water supply with existing area and classification. Water management is carried out by fulfilling irrigation water needs and the availability of water using a rotation system. The water balance is found that there is a lack of more water when using the existing area to calculate irrigation water requirements compared to using the area area. The percentage of rotational utilization and classification of availability discharges shows that rotation reduces the number of deficit events that still exist when the analysis is classified, but the rotation does not eliminate all of the deficit events. The largest percentage increase in volume occurred in the Kaiti Samo irrigation area for paddy-paddy-paddy cropping patterns in July, the volume of group percentages to availability was -6% after the percentage rotation increased 35% to 29%.
Keywords : Irrigation, existing area system, classification system, rotation system, water balance.
