Abstract
The micro watershed area of the Leuwi Padjadjaran II reservoir has undergone land use changes, and the analysis about land use changes is carried out based on 2011 map and 2021 map of land use. Changes occur as a result of increasing open and closed land at the same time, and changes in research land use can have an impact on the hydrological cycle. The surface runoff value is one of the hydro-logical cycles studied in this research. The purpose of this research was to deter-mine the presentage surface runoff in 2011 and 2021 based on land use change. The runoff value was calculate using the Cook method. Cook's method has four different factors, such as topography, soil infiltration, surface storage, and land cover vegetation. Based on the results of research conducted, it was found that the micro watershed area of the Leuwi Padjadjaran II reservoir experienced an in-crease in land use change and resulted in the predicted value of surface runoff in-creasing in 2021 when compared to 2011, which had a lower predictive value of surface runoff . The runoff prediction in the micro watershed area of the Leuwi Padjadjaran II are 66,3% from water discharge in 2011 and 66,8% from water discharge in 2021 which has an increase in runoff prediction of 0,5%.
