Abstract
Indonesia merupakan negara yang rawan gempa karena letaknya di pertemuan tiga lempeng tektonik dunia dan berada di jalur Cincin Api Pasifik. Kondisi ini menyebabkan tingginya risiko aktivitas seismik, terutama di wilayah selatan Jakarta seperti Kota Depok yang terancam oleh aktivitas Sesar Baribis. Untuk mengurangi risiko kerusakan bangunan akibat gempa, inovasi teknologi struktur tahan gempa sangat diperlukan. Penelitian ini menganalisis efektivitas sistem base isolation tipe High Damping Rubber Bearing (HDRB) sebagai alternatif pengganti dinding geser pada struktur gedung bertingkat sedang, khususnya pada Gedung Learning dan Dormitory BTN Eco Park. Studi ini menggunakan metode time history analysis serta pemodelan numerik berbasis perangkat lunak SAP2000 untuk mengetahui respons struktur 8 lantai dengan sistem HDRB terhadap beban gempa. Hasil analisis menunjukkan bahwa Penggunaan sistem base isolation tipe High Damping Rubber Bearing (HDRB) mampu meningkatkan periode struktur hingga 66% dan mengurangi gaya geser dasar maksimum sekitar sebesar 66% untuk arah X dan 80% untuk arah Y jika dibandingkan dengan sistem fixed base dan dinding geser. Selain itu, HDRB efektif mengendalikan simpangan antar lantai selama gempa dengan penurunan simpangan hingga sekitar 58-94%. Temuan ini menunjukkan bahwa HDRB secara signifikan mengurangi beban lateral dan kerusakan akibat gempa, sekaligus meningkatkan kenyamanan dan keselamatan penghuni. Implementasi teknologi HDRB memberikan dampak positif bagi rekayasa struktur tahan gempa di daerah berisiko tinggi seperti Depok, dengan membuka peluang desain bangunan lebih adaptif terhadap aktivitas gempa.
Indonesia is a country prone to earthquakes because it is located at the intersection of three of the world's tectonic plates and lies on the Pacific Ring of Fire. This condition leads to a high risk of seismic activity, especially in southern Jakarta areas like Depok City, which is threatened by the Baribis Fault. To reduce the risk of building damage from earthquakes, innovations in earthquake-resistant structural technology are essential. This study analyzes the effectiveness of the High Damping Rubber Bearing (HDRB) base isolation system as an alternative to shear walls in medium-rise building structures, specifically in the BTN Eco Park Learning and Dormitory Building. The study uses time history analysis and numerical modeling based on SAP2000 software to determine the response of an 8-story structure with the HDRB system to earthquake loads. The analysis results show that using a base isolation system with High Damping Rubber Bearings (HDRB) can increase the structure's period by up to 66% and reduce the maximum base shear force by approximately 66% in the X direction and 80% in the Y direction compared to a fixed base system and shear walls. Additionally, HDRB effectively controls interstory drift during earthquakes, reducing drift by approximately 58-94%. These findings indicate that HDRB significantly reduces lateral loads and earthquake damage, while also improving occupant comfort and safety. The implementation of HDRB technology has a positive impact on earthquake-resistant structural engineering in high-risk areas like Depok, opening up opportunities for building designs to be more adaptable to seismic activity.
