Abstract

Ncreased rainfall affects the people on the banks of the river. Utilization of water while maintaining sustainability is an indispensable action right now. Water jump is a flow of flow of flow (supercritical) in the upstream of the dam and will lead to water jump (hydrolic jump). Water jump events occur in the still pond (stilling basin) and the stilling basin design must be resistant to hydraulic forces and water velocity, thus not eroded by water jump events. Experiments in this study were conducted at the Hydraulics Laboratory of Civil Engineering Study Program Faculty of Engineering, Muhammadiyah University of Surakarta. This research uses flume tool with size 30 cm × 60 cm × 1000 cm, slope base 0,0058 channel. Mercu dam using ogee type. The stiling basin uses a USBR-II type with the addition of two variations of baffle block angles. The analytic results show some conclusions. First, the best baffle block arrangement to dampen the flow energy is a bendle type baffle with an angle of 75 ° placed at the beginning of the ojek pool in the ogge spill (series Z75.U). Second, the most effective baffle block position to reduce water jump length is the bendle-type baffle blocks with an angle of 75 ° placed at the beginning of the stiling basin at the ogee spill (series A75.U). Third, the work of the most effective baffle block shape and position in reducing turbulence downstream is baffe blocks with a 90 ° angle placed at the beginning of the stiling basin in the ogee sprocket (series B90.U).
