Abstract

Sediment control buiding Gendol Check Dam-13 (GE-C13) is one of buildings that was damaged by the eruptionof Merapi in 2010 and in 2018. Sabo dam GE-C13 has been completelyrenovated.The purpose of this study is to analyze sliding stability, shear and soil bearing capacity of the building during flooding with a 50 year return period (Q50). The analysis begins with the calculation of the design flood discharge by the Hydrographic Synthesis Nakayasu (HSS) method with a 50 year return period (Q50) and for the Sabo Dam Stability Analysis in accordance with SNI 2851-2015. The results of the design flood discharge with a 50 year return period of 51,401 m3 / sec. Stability Analysis at the time of flood conditions obtained value of sliding; Shear; Soil bearing capacity (6.39> 2; 2.21> 1.5; 10.74> 1.5 resepctively
