Abstract
Sistem isolasi dasar adalah salah satu sistem untuk meningkatkan kinerja struktur terhadap gaya gempa dengan menerapkan elemen fleksibel di dasar bangunan yang mampu meningkatkan periode redaman alami maupun redaman struktur secara signifikan serta menurunkan tingkat kerusakan struktur. Perencanaan gedung ini tidak hanya melakukan modifikasi struktur berupa base isolation tipe Friction Pendulum System (FPS) tetapi juga membandingkan respons kinerja struktur aslinya yang berupa sistem fixed base pada objek Gedung Rumah Sakit Kanker Dharmais di Jakarta. Pada penelitian ini, dilakukan permodelan struktur dengan adanya sistem FPS pada Gedung Rumah Sakit Kanker Dharmais di Jakarta. Permodelan struktur akan dianalisis dengan menggunakan nonlinear time history yang akan menghasilkan output besarnya periode struktur, displacement, inter-story drift dan gaya geser yang terjadi. Hasil tersebut nantinya akan dievaluasi untuk mengetahui keefektifan serta keandalan kinerja struktur dengan base isolation tipe Friction Pendulum System (FPS). Permodelan analisis struktur menggunakan program bantu.
Dari analisis dan perhitungan struktur base isolation memiliki periode 2,55 kali lebih besar dari periode struktur fixed base. Struktur base isolation memiliki gaya geser dasar yang lebih kecil daripada struktur fixed base yang menggunakan sistem SRPMK dengan selisih 11,63%. Struktur base isolation memiliki perpindahan yang lebih besar daripada struktur fixed base. Selain itu, penggunaan base isolation pada struktur dapat mereduksi drift rasio dengan selisih rata-rata 68,72% diarah X dan 61,76% diarah Y. Untuk Hasil perencanaan elemen struktur: tebal pelat lantai 120 mm, dimensi balok anak 350x500 mm, dimensi balok induk 600x800 mm, dan dimensi kolom 1000x1000 mm. Friction pendulum yang digunakan pada gedung ini adalah tipe SIP-D-HF-327 yang merupakan produk dari Maurer. Biaya material pada sistem struktur fixed base lebih besar daripada sistem struktur base isolation, yaitu senilai Rp27.841.263.974,68 untuk sistem struktur fixed base dan Rp23.939.313.973,17 untuk sistem struktur base isolation.

The base isolation system is a method to enhance structural performance against seismic forces by applying flexible elements at the base of a building, significantly increasing both the natural damping period and structural damping and reducing the level of structural damage. The design of this building not only involves structural modification using the Friction Pendulum System (FPS) type of base isolation but also compares the performance response of the original structure, which uses a fixed base system, in the Dharmais Cancer Hospital building in Jakarta. In this study, the structure modeling of the Dharmais Cancer Hospital building in Jakarta with the FPS system was conducted. The structural modeling will be analyzed using nonlinear time history analysis, which will produce outputs such as the structure's period, displacement, interstory drift, and shear forces. These results will be evaluated to determine the effectiveness and reliability of the structural performance with the Friction Pendulum System (FPS) type base isolation. Structural analysis modeling uses a supporting program.
From the analysis and calculations, the base isolation structure has a period 2.55 times greater than the fixed base structure's period. The base isolation structure has a smaller base shear force than the fixed base structure using the SRPMK system, with a difference of 11.63%. The base isolation structure has greater displacement than the fixed base structure. Additionally, the use of base isolation in the structure can reduce the drift ratio by an average of 68.72% in the X direction and 61.76% in the Y direction. The structural element design results are as follows: floor slab thickness is 120 mm, secondary beam dimensions are 350x500 mm, main beam dimensions are 600x800 mm, and column dimensions are 1000x1000 mm. The Friction pendulum used in this building is the SIP-D-HF-327 type, which is a product of Maurer. The material costs for the fixed base structural system are higher than those for the base isolation structural system. The material cost for the fixed base structural system is greater than the base isolation structural system, amounting to IDR 27.841.263.974,68 for the fixed base structural system and IDR 23.939.313.973,17 for the base isolation structural system.
