Abstract
Sekampung Hulu Watershed (DAS) is a catchment area for the Batutegi Dam. Changes in land use due to increasement of human need for land can affect the hydrological conditions of Sekampung Hulu Watershed. This research analyzed land use change to inflow characteristic of Batutegi Dam using descriptive analysis method by analyzing rainfall data, land use change data, inflow data and surface coefficient data. The results showed that there had been decreasing of forest area and the increasing of agriculture land, dry land, and shrubland. It affects the increasing of surface coefficient and decreasing of total inflow. The decrease in total inflow of batutegi dam in 2005 was 7.229,92 m3 / sec and in 2015 was 6.846,82 m3 / sec. This is due to the value of surface runoff coefficient in the Sekampung Hulu Watershed which increased in 2005 and 2015 by 0,23 to 0,34. The amount of surface coefficient value in 2005 and 2015 shows that the Sekampung Hulu Basin has been degraded, therefore it is necessary to restore the condition of the forest through reforestation and greening efforts to increase the water catchment area
