چکیده
The System of Rice Intensification (SRI), a water-saving paddy cultivation system, has been implemented in Indonesia. application SRI can increase water productivity. Salibu method applied to save seeds, costs, labour and the planting index paddy. However, when used other areas, yield is reduced by up 50 per cent from first harvest. A combination management needed production. this research experimental research. design irrigation system was made according technical design, then tested for automatic management. with method. data are climate data, level, discharge, content. temperature solar radiation determine potential evapotranspiration. results observations depth, volume content media, entering (rain infiltration, discharge), leaving (runoff, discharge) entered into balance equation (water balance). plant coefficient value included as factor multiplied evapotranspiration value. Then each observation optimized reducing error get Salibu. showed that appropriate fifth design. produce 4.7 tons/ha (SRI method) yields 8 tons/ha. 1738 litres, production 1.2 kg/m3.
