Abstract
Indonesia merupakan negara yang terletak pada pertemuan lempeng besar di dunia dan beberapa lempeng kecil yang menyebabkan potensi terjadinya gempa sangat besar. Salah satu sumber gempa yang teridentifikasi adalah zona sesar aktif di bagian barat hingga bagian timur Indonesia. Riset geologi terbaru yang dipublikasikan oleh Geophysical Research Letter (2016) menunjukan bahwa adanya patahan bernama Sesar Kendeng yang melintang sejauh 300 kilometer dari selatan Semarang, Jawa Tengah, hingga Jawa Timur dengan pergerakan 0,05 milimeter per tahun. Sehingga, penduduk Jawa Timur perlu mewaspadai gempa yang akan terjadi akibat sesar Kendeng tersebut. Kondisi inilah yang menuntut supaya kontruksi bangunan yang akan dibangun maupun selesai dibangun harus di evaluasi sehingga masih memenuhi kaidah bangunan tahan gempa agar bangunan tidak mengalami kegagalan saat terjadi gempa. Pada penelitian ini digunakan metode DSHA (Deterministic Seismic Hazard Analysis) untuk memperoleh acceleration time history pada batuan. Karena Indonesia masih minim catatan gerakan tanah, maka digunakan persamaan fungsi atenuasi untuk mengskalakan atau matching data riwayat waktu percepatan negara lain untuk dijadikan data riwayat waktu percepatan di lokasi yang ditinjau. Lalu dilanjutkan dengan SSA (Site Specific Analysis) untuk merambatkan percepatan gempa dari batuan menuju permukaan. Percepatan gempa yang ada di permukaan inilah yang digunakan sebagai beban gempa pada bangunan-bangunan infrastruktur. Dari hasil analisa struktur dengan memasukan beban simulasi gempa Sesar Kendeng, beberapa elemen struktur baik balok, kolom, maupun sambungan mengalami overstress. Sehingga elemen-elemen struktur yang mengalami overstress perlu dilakukan perkuatan untuk mengantisipasi terjadinya gempa Sesar Kendeng di Surabaya.

Indonesia is a country located at the confluence of large plates in the world and several small plates which cause the potential for a very large earthquake. One of the identified earthquake sources is the active fault zone in the western to the eastern part of Indonesia. The latest geological research published by the Geophysical Research Letter (2016) shows that there is a fault called the Kendeng Fault that crosses 300 kilometers south of Semarang, Central Java, to East Java with a movement of 0.05 millimeters per year. Thus, the population of East Java needs to be aware of the earthquake that will occur due to the Kendeng fault. This condition requires that the construction of buildings that will be built or completed must be evaluated so that they still meet the principles of earthquake-resistant buildings so that the building does not fail when an earthquake occurs. In this study, the DSHA (Deterministic Seismic Hazard Analysis) method was used to obtain acceleration time history in rocks. Because Indonesia is still lacking in land movement records, the attenuation function equation is used to scale or match the time history of acceleration of other countries to be used as historical data when accelerating at the location to be reviewed. Then proceed with SSA (Site Specific Analysis) to propagate earthquake acceleration from rock to surface. This acceleration of the earthquake on the surface is used as an earthquake load on infrastructure buildings. From the results of structural analysis by including the load of the Kendeng Fault earthquake simulation, several structural elements, both beam, column, and connection, have overstressed. So that the overstressing structural elements need to be strengthened to anticipate the occurrence of the Kendeng Fault earthquake in Surabaya
