Abstract
It is not the earthquake but the collapse of the building and infrastructure that will cause the damage and the loss of human lives. To mitigate these hazards, the building and infrastructure need to be designed such that will not collapse due to earthquake. This paper presents the procedure for generating time histories at ground surface for Jakarta area. Required data to generate these modified time histories were extracted from the Team for Revision of Seismic Hazard Maps of Indonesia 2010. The results are used as input motions in dynamic time history analysis for predicting earthquake design loads for infrastructures, such as bridges such that those structures can be designed to bear the impact of an earthquake and prevent collapse.
Keywords: Time histories, hazard de-aggregation, ground surface
Abstrak
Bukan disebabkan gempa bumi tetapi keruntuhan bangunan dan infrastruktur yang menyebabkan kerosakan dan kehilangan nyawa manusia. Bagi mengurangkan bahaya sebegini, bangunan dan infrastruktur perlu direkabentuk supaya tidak runtuh disebabkan oleh gempa bumi. Kertas kerja ini membentangkan prosedur bagi menjana modified time histories di permukaan tanah untuk kawasan Jakarta. Data yang diperlukan untuk menghasilkan modified time histories diambil daripada Kumpulan Penyemakan Peta Bahaya Seismik Indonesia 2010. Keputusan digunakan sebagai input gerakan dalam analisis dynamic time history bagi meramal beban rekabentuk gempa bumi untuk infrastruktur, seperti jambatan agar struktur sebegini boleh direkabentuk bagi menanggung kesan gempa bumi dan mencegah keruntuhan.

1.0 INTRODUCTION
According to the current Indonesian Seismic Hazard Map published in 2010 by the Indonesian Public Work Department, Jakarta is considered as a high seismicity area which means that Jakarta is potentially affected by earthquake hazards. Dense populated and many man-made structures and infrastructures in Jakarta area can significantly increase the hazards. The collapse of the infrastructures will cause the damage and loss of human lives. In order to alleviate hazards and losses due
to earthquake, seismic design loads need to be applied in design practice in Jakarta area. To predict that loads requires ground surface time histories such that the infrastructures can be designed to bear that loads and prevent collapse.
This paper presents procedure for generating time histories at ground surface for Jakarta area. This was conducted by modifying time histories given in Indonesian Earthquake Hazard Map prepared by Team for Revision of Indonesian Seismic Hazard Maps of Indonesia 2010 [1]. The procedure was started by

Graphical abstract Abstract
An instrumented pile load test was conducted for a 1.2m diameter bored pile at Putrajaya to verify pile performance towards geotechnical design. This test pile was instrumented with new monitoring technique using distributed strain sensing known as Brillouin Optical Time Domain Analysis (BOTDA) and compared with conventional sensors, i.e. vibrating wire strain gauge, LVDT (linear variable differential transformer) and dial gauge. This manuscript includes the description of subsurface conditions consisting of weathered granitic residual soils, test pile installation and instrumentation setup of Maintain Load Test (MLT). Field measurement results such as the load transfer response and average unit shaft resistance using the distributed fibre optic strain sensor were well matched with the results using the conventional sensors. However, the distributed fibre optic strain sensor has the added advantage of detecting the localized defect such as pile necking, bending, and overall behaviour of bored pile effectively.
Keywords: Bored pile, Fibre-Optic sensing, BOTDA, maintain load test
Abstrak
Satu ujian beban cerucuk telah dijalankan di Putrajaya pada sebatang cerucuk terjara berukuran 1.2m diameter untuk mengesahkan prestasi cerucuk terhadap rekabentuk geotekniknya. Cerucuk yang diuji ini dipasang dengan jenis instrumen yang menggunakan teknik pemantauan baharu yang boleh mengesan terikan secara tersebar. Teknik ini dinamakan Brillouin Optical Time Domain Analysis (BOTDA) dan keputusannya dibandingkan dengan sensor konvensional seperti tolok terikan dawai bergetar, LVDT dan tolok dial. Kandungan manuskrip ini termasuk perihal geoteknik terdiri daripada tanah granit terluluhawa, kaedah pemasangan gentian optik dan persediaan instrumentasi untuk Ujian Cerucuk Statik. Keputusan ujian tapak seperti tindak balas pemindahan beban dan unit rintangan aci purata menggunakan kaedah terikan tersebar gentian optik adalah memadani keputusan yang menggunakan sensor konvensional. Walau bagaimanapun, sensor terikan tersebar gentian optik mempunyai kelebihan tambahan yang mana ia boleh mengesan kecacatan setempat seperti perleheran, lenturan dan pergerakan keseluruhan cerucuk terjara secara berkesan.
