<b></i>Abstract :</b><i><p align=\"justify\"> <br /> This research was carried out in Sukawening and Wanaraja area, district of Garut. The objective of this research is to know and learn the well potency of SDGR 03, SDGR 07, SDGR 05, and SDGR 08, which is used for irrigation. Furthermore, to decide the planting pattern based on groundwater availability in the well, moreover is to design the irrigation net which is suitable with topography, the demand of rice and planting area. <br /> <p align=\"justify\"> <br /> The method used in this research was collecting field\'s data, observations, and conducting the field-testing, which was then followed by analyzes. The pumping discharge is based on optimum discharge as follows; SDGR 03 well in amount of 19 It/s, SDGR 07 well in amount of 14 lt/s, SDGR 05 well in amount of 11 his, and SDGR 08 well in amount of 15 It/s. <br /> <p align=\"justify\"> <br /> The beginning of planting will be decided according to rainfall and local climate at the lowest of groundwater demands. It is agreed that the high time to start planting is on November 15th with planting pattern rice, palawija crops, and palawija crops for Sukawening area. Meanwhile the beginning of planting at Wanaraja area is on December 15t with planting pattern rice, palawija crops, and palawija crops. Particularly in SDGR 05 the planting pattern is palawija crops, palawija crops, and palawija crops. <br /> <p align=\"justify\"> <br /> The design of irrigation network for SDGR 03 area is type 5 with Pump SP 60-8, SDGR 07 area is type 5 with Pump SP 46-6, SDGR 05 type 4 with Pump SP 46-6, and SDGR 08 is type 5 with Pump SP 46-4.
