<b>Abstract:<p align=\"justify\"> <br /> Becouse of groundwater limitation, the utilization of groundwater is needed as efficient as possible. The objective of this research is to identify groundwater potential and to manage the grounwater resources for irrigation to obtain optimal benefite, it can be achieved by desiding cropping patern and starting planting season based on the groundwater resources. The research was conducted in Jatibali rural, Ranomeeto distrik Kendari regency, south-east of Sulawesi Propince, this was based on the primary data consisting of farm analysis and cropping system that be done by farmers and the secondary data consist of well data (pumping test, logging, litology, and well construction), climatology, geology, hydrogeology, geomorfology, and chemist analysis of groundwater. The optimation was conducted by using QSB (Quantitative Sytem Business) program.The result of the research show that the aquifer in the study area is confine aquifer lying between 45 m - 100 m depth from the surface. Total groundwater potential is 70 l/sec. The Optimum discharge varies in each well, namely In P11-KDI is 6,4 1/sec, P12-KDI is 8,7 1/sec, P13-KDI is 14,5 1/sec and P15-KDI 15 1/sec. The average of transmisibility is 255,962 ma/day and the average of hydrolik conductivity is 9.71 x 10-5 m/sec. The result of optimation show that Desember is the best starting of the origin of planting season. Generaly, croping paters that can be recomended in the study area are rice - rice - corn and rice+corn - rice - corn, with total profit per year is Rp 253,788,904.00,- (in total area of wet land is 142 ha).
