An essential component in an earthquake-resistant building is a seismic base isolator. Nowadays, seismic base isolators are usually produced from synthetic rubber such as Chloroprene Rubber (CR). This research investigated the possibility of combining CR and natural rubber. Specimens were prepared with different ratio compositions of CR and NR (SIR20).

Indonesia is a country located at the confluence of the Indo-Australian plate, the Eurasian plate, and the Pacific plate. All three are active and potentially active plates causing tsunamis and earthquakes. Earthquakes occurred in several areas of Indonesia, such as the Aceh earthquake on December 2004 with an earthquake scale of 9.1-9.3, then the Yogyakarta earthquake on May 2006 with an earthquake scale of 6.3, and in early August 2018, an earthquake with a magnitude of 7 struck the city of Lombok, West Nusa Tenggara.
