Rain gauges in Indonesia are often unevenly distributed, with significant gaps in data availability. As an alternative, satellite precipitation products (SPPE), such as CHIRPS and GPM-IMERG, are increasingly used for precipitation estimates. Additionally, discharge data is frequently unavailable for extended periods, making rainfall-discharge modeling essential. This study aims to evaluate the performance of two SPPEs, CHIRPS and GPM-IMERG, in the Gembong watershed and identify the best rainfall
