Abstract
Berdasarkan Peta Sumber Bahaya dan Gempa Bumi Indonesia Tahun 2017, Kota Surabaya dilintasi oleh dua sesar (patahan) aktif yang berpotensi menyebabkan gempa bumi hingga 6,5 SR (Widodo,2017). Hal tersebut perlu dijadikan pertimbangan dalam merencanakan infrastruktur di Kota Surabaya sebagai tindakan mitigasi bencana. Salah satu perkembangan teknologi dalam perlindungan struktur terhadap gempa bumi adalah dengan menggunakan sistem isolasi dasar (base isolator). Base isolator merupakan sebuah sistem yang diletakkan di atas pondasi untuk memisahkan pondasi dengan struktur diatasnya sehingga ketika terjadi gempa getaran akan diterima pondasi dan diredam oleh base isolator terlebih dahulu sebelum diterima struktur utama. Sistem ini dapat diterapkan pada struktur baru maupun sebagai tambahan struktur yang sudah ada. Gedung Skysuites Soho Surabaya merupakan objek perancangan yang berfungsi sebagai apartemen dengan 21 lantai akan dirancang ulang dengan menggunakan base isolator tipe High Damping Rubber Bearing (HDRB) dan Peta Gempa Tahun 2017. Perencanaan yang dilakukan meliputi perencanaan struktur sekunder, struktur primer, base isolator, dan pondasi. Dari hasil perhitungan dan analisis, diperoleh dimensi tebal pelat sebesar 12cm, dimensi balok anak terbesar 30x40cm, dimensi balok induk terbesar 40x60cm, dimensi kolom terbesar 90x90cm, base isolator HDRB dengan tipe produk HH060X6R yang memiliki diameter rubber 600mm, pondasi direncanakan dengan bored pile berdiameter 80cm dengan kedalaman 36m.

Based on the Peta Sumber Bahaya dan Gempa Bumi Indonesia Tahun 2017, Surabaya is crossed by two active faults which potentially causing earthquakes up to 6.5 SR (Widodo, 2017). This should be taken as consideration in planning infrastructure in Surabaya as a disaster mitigation action. One of the technological developments in protecting structures against earthquakes is to use a base isolator system. Base isolator is a system that is placed on a foundation to separate the foundation with the structure above it so that when an earthquake occurs, the vibration will be received by foundation and muted by the base isolator before received by the main structure. This system can be applied to new structures or in addition to existing structures. Skysuites Soho Surabaya building is a design object as 21-storey apartment that will be redesigned using the High Damping Rubber Bearing (HDRB) type and Peta Gempa Tahun 2017. The design includes secondary structure, primary structure, base isolator, and foundation. From the results of calculations and analysis, the dimensions of the plate are 12cm thick, the largest dimensions of the secondary beam is 30x40cm, the largest dimension of the main beam is 40x60cm, the largest dimension of column is 90x90cm, base HDRB isolators are HH060X6R which have 600mm rubber
diameter, bored pile foundation 80cm in diameter with 36 m depth.
