Earthquake dampers in a building function to reduce lateral deformation that can cause building failure, as well as to increase the feasibility of the building's reliability function. Currently, there are various models and types of earthquake damper innovations such as natural rubber base isolators, HDRB (High Damping Rubber Bearing), Fluid Viscous Damper (FVD), and Tuned Mass Damper. A High Damping Rubber Bearing (HDRB) is an elastomeric bearing type base isolator that uses rubber to dampen the earthquake force that occurs in the building structure. This study aims to evaluate the effectiveness of the placement of HDRB-type earthquake dampers in apartment buildings in the city of Jakarta, using the Etabs 20 Program, so that the determination of the location of the earthquake damper can be analyzed precisely. Earthquake dampers in a building function to reduce lateral deformation that can cause failure of the building, as well as to increase the feasibility of the building's reliability function. Currently, there are various models and types of earthquake damper innovations such as natural rubber base isolators, HDRB (High Damping Rubber Bearing), Fluid Viscous Damper (FVD), and Tuned Mass Damper. An HDRB is an elastomeric bearing type base isolator that uses rubber to dampen the earthquake force that occurs in the building structure. This study aims to evaluate the effectiveness of the placement of HDRB-type earthquake dampers in apartment buildings located in the city of Jakarta, using the Etabs 20 Program, so that the determination of the location of the earthquake damper can be analyzed precisely. From this study, the results obtained were a large reduction in the influence of earthquakes on a building with the use of HDRB dampers on all columns of 81.16%, from 21,882 mm to 4,122 mm, and in the combination of the use of dampers on the clamp placement, it became 18.70% with a deviation of 17,791 mm. It can be concluded that the placement of earthquake dampers can be effectively applied to a building to overcome earthquake forces and increase the reliability of the building structure.
