Abstract
The use of base isolation as an earthquake mitigation technology is an innovative solution in designing earthquake-resistant building foundations, especially in areas with high seismic activity. This study aims to analyze the performance of base separation in damping earthquake forces received by the upper structure. Literature studies were conducted by referring to various previous studies showing that this technology can dampen the structural response to ground vibrations, extend the vibration period, and increase the overall stability of the building. The analysis was carried out by modeling the base separation system using simulation software to study its effect on base shear forces and structural cooling. The simulation results show that base separation can dampen base shear forces by up to 58% compared to conventional structures without isolation. This technology also shows advantages in maintaining structural integrity during major earthquakes. These findings are expected to be a reference for building design to improve the safety and resilience of building structures in earthquake-prone areas.

Abstrak
Pemanfaatan base isolation sebagai teknologi mitigasi gempa bumi menjadi solusi inovatif dalam perancangan pondasi bangunan tahan gempa, terutama pada daerah dengan aktivitas seismik tinggi. Penelitian ini bertujuan untuk menganalisis kinerja base isolation dalam meredam gaya gempa yang diterima oleh struktur atas. Studi literatur dilakukan dengan mengacu pada berbagai penelitian terdahulu yang menunjukkan bahwa teknologi ini dapat meredam respon struktur terhadap getaran tanah, memperpanjang periode getaran, dan meningkatkan stabilitas bangunan secara keseluruhan. Analisis dilakukan dengan memodelkan sistem base isolation menggunakan perangkat lunak simulasi untuk mempelajari pengaruhnya terhadap gaya geser dasar dan deformasi struktur. Hasil simulasi menunjukkan bahwa base separation mampu meredam gaya geser dasar hingga 58% dibandingkan dengan struktur konvensional tanpa isolasi. Teknologi ini juga menunjukkan keunggulan dalam menjaga keutuhan struktur saat terjadi gempa besar. Temuan ini diharapkan dapat menjadi acuan bagi perancang bangunan untuk meningkatkan keamanan dan ketahanan struktur bangunan di daerah rawan gempa.
