Failure Analysis of Irrigated Areas as a Drought Reflection to Strengthen Food Security

Drought in the irrigated area will cause paddy fields to not produce well or land failure which in turn will cause crop failure. Harvest failure will weaken food security and will become a national problem if it occurs simultaneously. Land failure analysis can avoid this problem, at least reduce the losses that occur because the land cannot be harvested. Drought occurs because of an imbalance in demand and availability of water in the field. The formula for regulation of water balance so as to produce optimum agricultural production has not been verified under existing conditions. Formula built with reliable discharge factors, irrigation water requirements, efficiency of irrigation channels, water losses in irrigation channels, cropping patterns and planting schedules. The result of the research is the analysis of the prediction of land failure verified by the existing conditions, namely the recommended area to be reduced or planted with palawija based on the cropping pattern and planting schedule of the optimum regulation results. Besides that, it also produces effective rainfall for the Cimulu irrigation area, optimum water requirements, and production yield estimates based on the analysis of minimum land failure predictions.
