Most parts of Indonesia are located at high-risk seismic regions. Therefore, it is necessary to seriously consider earthquake in designing the seismic-resistant buildings. One of the most effective methods to reduce the impact of the earthquake force is to introduce the use of the elastomeric rubber base isolation as an effective earthquake damper. Indonesia as a tropical country has many sources of raw materials particularly rubber. This can be potential as a main basic need for producing an optimum elastomeric rubber base isolation system. This paper determined an approach method of constitutive low-grade rubber to get the best fitting with experimental data. Five deformation models such as Mooney-Rivlin, Ogden, Arruda-Boyce, Neo-Hookean, Yeoh models compare to uniaxial test were adopted to simulate the characteristics of rubber materials used in base isolation. From the analysis, it can be concluded that Yeoh model give the best fitting and the most accurate to the test data even in limited test data.
