Revetment Sistem Panel Serbaguna (SPS) or Schematic System Precast (SPS) Revetment is latest innovation of SPS technology. It has been applied for various area of civil engineering such as bridge, dams and irrigation channel. For this upgrading, SPS has been tested in Hydraulic Laboratory of Experimental Station for Coastal Engineering Ministry of Public Works and Housing as revetment. SPS is tested with 14 scenarios of various wave steepness and water depth to determine the wave run-up characteristic. All hydraulic performance of SPS for each scenario is recorded with video camera. Using image processing technique, we calculate the wave run-up height for each scenario. From all scenarios, the wave run-up only happen in scenarios with water depth of 0.65 m while the rest only experience wave overtopping. Comparing to the classical Iribarren Number graph, relative wave run-up height on SPS revetment is higher than other type of revetment such as Riprap Arhens, Riprap Gunbak, Batu Pecah, Qudripod, Dolos and Tetrapod but below Sisi Miring. For Sisi Miring Revetment, the maximum relative wave run-up height (Ru/Hm0) is 2.5 for Iribarren Number (Ir) = 2.5 as for SPS revetment, it is approximately 2.4 for Ir = 11.
