In a hydropower planning plan, an important factor that must be known is: the amount of monthly discharge and flagship discharge, as well as the river canfography.
To calculate the amount of water availability in Cibuni watershed for the needs of the PLTMH, the discharge analysis of the F.J MCOK method and the NRECA method and the magnitude of the potential evapotranspiration use the Penman method. Hujang bulk data used is rainfall data obtained from 5 rain stations in the form of monthly rainfall for 16 years from 1996-2011.
From the calculation of the F.J Mock method for the availability of water in Cibuni Das, a maximum discharge of 28.46 m3 / dt and minimum water discharge of 0.11 m3 / dt. As for the NRECA method is a maximum water discharge of 26.50 m3 / dt and minimum water discharge of 2.77 m3 / dt. Based on the calculation results, for the F.J Mock method is more suitable for use in Cibuni watershed compared to Nreca.
