Abstract :
Weir is a building located in the water that serves to raise the water level of the river with a specific purpose. Weir buildings are required to be able to withstand the forces of overturning, shearing and soil bearing capacity. The condition of the Setail weir in Jambewangi Village, Sempu District, Banyuwangi Regency, was damaged in the crest and stilling pond. In conditions like this, it must be recalculated, especially in the condition of the weir during an earthquake. The research I did discusses the new design for the weir with the calculation of earthquake forces referring to the 2017 earthquake zoning map. The data used in this study are hydrological data, soil data and seismic zone review data. The design flood discharge analysis uses a 50 year period of 426.11 m3 /s. Hydraulics analysis using a fixed weir with an ogee type crest with an upstream slope of 1: 1. Analysis of the stability of the weir obtained the SF value using the plaxis 8.2 program of 3.2816 > 2, it can be concluded that for this latest weir design, we can proceed to the planning stage.
