Abstract
DKI Jakarta memiliki risiko kegempaan tinggi yang menuntut standar keamanan ekstra bagi fasilitas vital, seperti Gedung Pendidikan RS PON Prof. Dr. dr. Mahar Mardjono. Gedung 11 lantai ini memerlukan kinerja struktur yang tidak hanya mencegah keruntuhan, tetapi juga menjamin keberlangsungan operasional pasca gempa. Proyek akhir ini bertujuan memodifikasi desain struktur gedung tersebut menggunakan teknologi Base Isolation tipe High Damping Rubber Bearing (HDRB) untuk mereduksi energi seismik.Perencanaan meliputi permodelan struktur, analisis beban gempa respons spektrum komposit, serta perhitungan efisiensi pondasi. Hasil analisis menunjukkan bahwa penggunaan HDRB efektif memperpanjang periode fundamental struktur secara signifikan menjadi 4,758 detik (Arah X) dan 4,322 detik (Arah Y). Hal ini berdampak langsung pada reduksi Gaya Geser Dasar Seismik sebesar 46,94% pada arah X dan 33,62% pada arah Y, dengan simpangan antar lantai yang tetap terkontrol aman. Dampak efisiensi paling signifikan terlihat pada struktur bawah. Kompleksitas Pile Cap berhasil disederhanakan dari 13 tipe pada desain eksisting menjadi hanya 4 tipe pada desain alternatif. Selain itu, terjadi pengurangan jumlah tiang pancang secara drastis dari 700 titik menjadi 476 titik. Secara keseluruhan, sistem HDRB terbukti mampu meningkatkan kinerja seismik bangunan sekaligus menawarkan efisiensi material dan kemudahan konstruksi yang tinggi.

DKI Jakarta possesses a high seismic risk that demands extra safety standards for vital facilities, such as the Educational Building of RS PON Prof. Dr. dr. Mahar Mardjono. This 11-story building requires structural performance that not only prevents collapse but also guarantees operational continuity post-earthquake. This final project aims to modify the building's structural design using High Damping Rubber Bearing (HDRB) Base Isolation technology to reduce seismic energy. The planning process includes structural modeling, composite response spectrum seismic load analysis, and foundation efficiency calculations. The analysis results indicate that the use of HDRB effectively and significantly prolongs the structure's fundamental period to 4.758 seconds (X-direction) and 4.322 seconds (Y-direction). This directly results in a reduction of the Seismic Base Shear by 46.4% in the X-direction and 33.62% in the Y-direction, with inter-story drift remaining safely controlled. The most significant efficiency impact is observed in the substructure. The complexity of the Pile Caps was successfully simplified from 13 types in the existing design to only 4 types in the alternative design. Furthermore, there is a drastic reduction in the number of piles from 700 points to 476 points. Overall, the HDRB system is proven capable of enhancing the building's seismic performance while offering high material efficiency and ease of construction.
