Abstract

Gempa bumi Banten berkekuatan 6,2 Mw pada tanggal 23 Januari 2018 menarik perhatian para ahli tentang pentingnya pengetahuan mengenai percepatan tanah maksimum dan spektra percepatan di permukaan untuk wilayah DKI Jakarta. Hasil PGAM, SMS, dan SM1 memegang peranan penting dalam peraturan desain seismik. wilayah DKI Jakarta. Hasil PGAM, SMS, dan SM1 memegang peranan penting dalam peraturan desain seismik. Tujuan dari penelitian ini adalah menentukan PGAM, SMS, dan SM1 untuk wilayah DKI Jakarta menggunakan Probabilistic Seismic Hazard Analysis (PSHA). Data yang digunakan adalah katalog gempa bumi BMKG, ISC, dan USGS dari tahun 1900 – 2018. Hasil analisis menunjukkan bahwa nilai PGAM untuk untuk probabilitas terlampaui 2% dalam 50 tahun di wilayah DKI Jakarta bervariasi dari 0,35 – 0,5 g. Sementara itu nilai SMS, dan SM1 untuk untuk probabilitas terlampaui 2% dalam 50 tahun di wilayah DKI Jakarta bervariasi dari 0,65 – 1g dan 0,8 – 1g. Nilai PGAM, SMS, dan SM1 relatif lebih tinggi di wilayah Kota Jakarta Selatan, Kota Jakarta Barat, dan Kota Jakarta Utara.

 

 

The Mw 6.2 Banten earthquake on January 23, 2018, draws researchers’ attention to the importance of information about Peak Ground Acceleration and spectral acceleration on the surface for the DKI Jakarta area. The results of PGAM, SMS, and SM1 play an important role in the rules of seismic design. The purpose of this study was to determine PGAM, SMS, and SM1 for the DKI Jakarta area using Probabilistic Seismic Hazard Analysis (PSHA). The data used are the earthquake catalog BMKG, ISC, and USGS from 1900 - 2018. The analysis shows that the value of PGAM for DKI Jakarta varies from 0.35 – 0.5 g. Meanwhile, the value of SMS, and SM1 varies from 0.50 - 0.1 g and 0.8 - 1 g. The values of PGAM, SMS, and SM1 are relatively higher in the area of South Jakarta City, West Jakarta City, and North Jakarta City.
