The Operation Management Model of Intermittent Irrigation in Cihea Irrigation Area In Cianjur Regency

Abstract

The availability of water for irrigation has been decreasing and the need for other sectors has been increasing rapidly over the time. Whereas, there are also several environmental damages due to the serious exploitation of natural resources in many places. This situation causes the irrigation system has to be managed efficiently and effectively. In irrigation modernization, the implementation of intermittent irrigation is the right choice, because it is a water-saving irrigation technology. The model operation of intermittent irrigation operation that is built is a calculation model to determine the interval of irrigation water provision and the amount of irrigation water, which begins with the planning of the cropping pattern. The irrigation operation management model with intervals of providing irrigation water for 3 days developed in the Cihea Irrigation Area, Cianjur Regency has an influence on irrigation performance. The paddy planting season in Cihea, Cianjur Regency with intermittent irrigation operation, was able to achieve irrigation water productivity values > 0.8-1.0 kg / m3 (advanced stage in modern irrigation management).
