Abstract

The increasing of population has led to the rise of need for water irrigation and food production. However, water needs are still sensitive which in turn can cause competition and conflict. One way to deal with it is to monitor the quality and quantity of river water expected to be appropriate based on its usefulness. The river water is expected still within the limits of tolerance of water quality criteria and the appropriate utilization of large quantity of water still needs to be fulfilled. Therefore, a study of quality and quantity of Pangkajene River used for irrigation Pangkep District was conducted.The data of climatology, hydrology were collected in order to compute irrigation the water requirements, the quantity of discharge mainstay, to analyze the water balance, the water samples, to test the water samples in the laboratory, and then to analyze the results . The results indicated the Biological Oxygen Demand (BOD) of Pangkajene River had exceeded the water quality standards by grade IV Quality Standards Water Quality Regulation of South Sulawesi Governor. This is due to the effects of sewage and people around the River. So it can be advised that domestic wastewater should not be discharged directly into the river / water bodies but it must be processed first and all industrial wastewater producers are required to have an installation wastewater treatment plant (WWTP). The quantity of discharge mainstay seems to have significant fluctuation in the river of the water balance Pangkajene and water shortage in June I, II June, July I, August I, II August, September I, and September II and it is recommended for planting crops in the months with less discharge in order to reduce the occurrence of water shortages.
