The cropping pattern is based on the Decree of Regent (SK Bupati) that rice-rice-palawija crop which its water distribute is continuous flow, its cropping intensity is only achieving 290 %. The developed cropping pattern in the community is that rice-rice-rice with the cropping intensity is 254 % and continuous flow. To improvethe good cropping intensity based on the SK. Bupati's cropping pattern with the existing cropping pattern which needs the cropping pattern regulation and the intermittent water distribute for block I toward the block I1 by the treatment of factor K of 0.78 for rice-rice-palawija crop and faktor K 0.47 is that rice-rice-rice crop. To increase the land use effectiveness and cropping equalization for the farmers in order that conflicts is not resulting in, so the mix cropping pattern is that rice-rice-rice+palawija crop with the factor K = 0.60, water distribute with the intermittent system on the area divide on DI. In optimum for dry season I1 (MT III), is that : O- Rice cropping 1,766.39 ha (70 %} k Palawija cropping 757.03 ha (30 %) By appling the cropping pattern of rice-rice-rice+palawija crop, water distribute system is flowed intermittently with the factor K of 0.6 on August I, August I1 and September I. Based on the cropping pattern of rice-rice-rice+palawija crop can improve the cropping intensity from 270 % becoming 300 %. <br /> <br />
