South Sulawesi is one of the nine provinces in Indonesia that has the highest contribution to the national income and its leading sector in agricultural crops including rice. The planning of planting patterns is highly dependent on the size of the intensity of rainfall in a particular area. Therefore, these conditions can have an impact on the level of suitability of crops to be planted. The purpose of this study has been to analyze the water balance and identify the optimal planting pattern. On the basis of rainfall data obtained from 4 rainfall stations, which are Mangkoso station, Manuba station, Mareppang station, and Ralla station, during the period of 25 years (1996 – 2020), the analysis to determine the average semi-monthly rainfall can be carried out. The results show that the maximum value of irrigation water requirements for rice-rice-palawija planting pattern obtained for simulation 1 has occurred on 1 September by 1.66 m3 /s, while the minimum value has occurred on 1 January, 2 May, and 2 December by 0.23 m3/s. As a conclusion, the maximum value in simulation 3 has occurred on 2 October by 1.65 m3 /s, while the minimum value has occurred on 1 February and 1 June by 0.23 m3 /s. The optimization results show that the most optimal cropping pattern is planting 100 of rice in the first and second planting seasons with an area of 717 Ha and 71 planted with palawija in the third planting season of 509.68 Ha.
