Digunakan rekaman data seismik 12 Agustus-12 September 2016 dari 33 stasiun yang ada pada jaringan 7G Seismic Temporary Network GFZ GeoForschungsZentrum ndash; German Reserarch Centre for Geosciences Helmholtz Centre Postdam dan BMKG Badan Meteorologi Klimatologi dan Geofisika , yang dianalisis menggunakan JISVIEW, sebuah program analisis gempabumi. Program simulps12 digunakan untuk melakukan proses inversi tomografi simultan. Dari rekaman seismik yang ada teranalisis 264 kejadian gempabumi sebelum relokasi yang kemudian menjadi 219 kejadian gempabumi setelah relokasi , yang digunakan dalam tahapan proses tomografi. Kejadian gempabumi yang ada diidentifikasi sebagai rangkaian kejadian gempabumi swarm, bukan kejadian gempabumi tektonik biasa non swarm yang memiliki pola foreshock-mainshock-aftershock. Dari gambar hasil tomografi diketahui adanya daerah dengan perturbasi nilai Vp tinggi diasumsikan sebagai magma yang mengalami intrusi magmatik dimasa lalu dan telah mendingin menjadi bagian batuan beku. Vp rendah dikedalaman diasumsikan sebagai intrusi magma yang sedang terjadi dari mantel bagian atas yang mendorong bagian lemah pada batuan beku dibagian kerak bumi bagian bawah diwilayah, sehingga mengakibatkan rangkaian gempabumi swarm pada akhir tahun 2015.

The process of tomography for seismic velocity structure P wave has been done using swarm earthquake data in Jailolo, Halmahera Barat, and North Molucca. The objectives of this research are determining the earthquake parameters and its hypocentre and epicentre around research areas, analysing the difference between swarm and non swarm earthquake tectonic earthquake, and analysing the structure of P wave velocity Vp structures and correlating the results with the local and regional geological structure that became the source of swarm earthquake phenomenon in 2015.

A 32 days August 12 September 12 2016 seismic data recording, from 33 seismic station in 7G Seismic Temporary Network of GFZ GeoForschungsZentrum ndash German Research Centre for Geosciences Helmholtz Centre Postdam and BMKG Agency of Meteorology, Climatology and Geophysics , is analysed using JISVIEW, an earthquake analysis program.

Simulps12 program is used to do the simultaneous tomography inversion. From the seismic recording, we analysed 264 earthquake events before relocation, and after relocation process we used 219 earthquake events to do the inversion process. The earthquake event that analysed in research areas is identified as a swarm earthquake sequence, not am ordinary tectonic earthquake.

From tomography imaging result we found a region high Vp perturbance values that interpreted as a igneous rock of magma bodies from previous magmatic intrusion in the past. A low Vp perturbance values in the depth is interpreted as on going magmatic intrusion from upper earth mantle layer that pushing the weak zones at lower earth crust layer that caused the sequence of swarm earthquake in 2015."

ABSTRACTChimney is a tall tubular structure consisting inner flue and windshield. ItsEarthquake resistance mechanism can be achieved by installing elastomeric rubberbearings and Tie Rods. The focus of this research is to analyze the effectiveness ofTie Rods in reducing seismic impact to the inner flues. The results show that thechange in Tie Rods? stiffness variation does not affect the response of thewindshield. Inner Flue does not function as tuned mass damper as its mass isrelatively small. But Tie Rods strongly affect Inner Flues? responses. Inner Fluesresponses are optimal when Tie Rod?s stiffness is varied increasingly down throughthe lower elevation of the structure."

"Studi ini meneliti tentang bangunan X bertingkat banyak di Jakarta yang dibangun di atas bangunan cagar budaya. Struktur yang terdiri dari struktur rangka baja dan sistem prategang digunakan sebagai balok transfer untuk memindahkan dan meneruskan beban-beban dari lantai-lantai atas ke kolom-kolom pendukung. Hasil penelitian ini menunjukkan terjadi peningkatan gaya geser, perpindahan, gaya dalam, dan kebutuhan penulangan seiring dengan bertambahnya jumlah lantai. Selanjutnya, dalam variasi jumlah strand pada kabel prategang, karakteristik dinamik dan kebutuhan tulangan yang terjadi relatif sama, namun perpindahan vertikal yang terjadi semakin kecil dengan bertambahnya jumlah strand yang digunakan. Profil baja yang digunakan semakin kecil dengan meningkatnya jumlah strand yang digunakan pada sistem prategang luar.

This study examines the multi-storey X-builing located in Jakarta, built above heritage building. Structure consisting of steel truss and external prestressing system is used as transfer beam to transfer and allocate loads from upper floors to supoorting columns.

This study shows an increase in shear force, displacement, internal forces, and the need for reinforcement as the number of floors increase. Furthermore, variation in the number of strands in prestressed cables gives relatively similar dynamic characteristic and reinforcement need, although vertical displacement that occurs gets smaller with increasing number of strands used. Steel profiles used are increasingly smaller as the number of strands used in external prestressing system increase."

"Penelitian ini membahas tentang bangunan X di Jakarta yakni bangunan gedung bertingkat di atas bangunan cagar budaya. Sesuai dengan peraturan yang ada, bangunan cagar budaya harus dilestarikan. Oleh karena itu, digunakan balok transfer di atas bangunan cagar budaya yang berperan memindahkan dan meneruskan beban ke kolom pendukung. Balok transfer dari rangka baja digunakan untuk mempermudah proses konstruksi.Adapun sistem transfer tidak boleh mengalami kegagalan di awal sehingga harus diperhitungkan terhadap suatu faktor kuat lebih. Karena Indonesia merupakan negara rawan gempa, perlu dilakukan analisis seismik dalam desain bangunan. Dalam peraturan gempa yang berlaku, bangunan dengan balok transfer juga harus diperhitungkan terhadap gempa arah vertikal. Penelitian ini menunjukkan peningkatan gaya geser, perpindahan, gaya dalam, dan kebutuhan penulangan seiring dengan bertambahnya jumlah lantai. Selanjutnya, dalam variasi sistem sambungan, diketahui bahwa bangunan dengan rangka transfer rigid lebih efektif penggunaannya dibandingkan rangka transfer dengan sambungan sendi. Perbedaan karakteristik dinamik dalam variasi sambungan tidak terlalu signifikan akibat kekakuan kedua bangunan yang hampir sama pula. Adapun desain bangunan bertingkat dengan rangka transfer pada penelitian ini dominan dikontrol oleh beban gravitasi.

This study discuss about X building in Jakarta that is multistory building above heritage building. According to the applicable regulations, the building of cultural heritage should be preserved. Therefore, transfer beam is used above heritage building which transfers and transmits load to its supporting columns. Transfer beam from steel truss is used to simplify the process of construction. The transfer system should not fail at the beginning so it must be considered againts an over strength factor. As Indonesia is a country that vulnerable to earthquakes, the seismic analysis should be done in the building design. Base on the aplicable regulation of earthquake, the bulding with transfer truss must also be considered to vertical direction of earthquake.

The study shows the enhancement in shear force, displacement, internal forces, and reinforcement requirement along with the increasing number of storey. Furthermore, in variation of connections system, is known that transfer truss with rigid connection is more effective than transfer truss with pinned connection. The differences of dynamic characteristics in the variation of connection are not too significant due to the stiffness of the two buildings are almost same. The design of multistory building with transfer truss in this study is predominantly controlled by gravity loads."

"Penelitian ini membahas mengenai metode desain sistem ganda dari struktur portal - dinding geser beton bertulang akibat beban gempa dengan analisis pushover. Tujuan penggunaan sistem ganda adalah untuk menghasilkan desain yang efisien dan efektif dalam perencanaan bangunan tahan gempa. Untuk memperoleh sistem ganda yang sesuai dengan peraturan gempa Indonesia, diterapkan tiga metode desain, yaitu : struktur portal dengan memperhitungkan keberadaan boundary element dari dinding geser, struktur portal dengan properti dinding geser yang dimodifikasi, dan struktur portal-dinding geser berinteraksi dengan pembesaran gaya geser tingkat berdasarkan faktor skala dari gaya geser dasar portal.Pada penelitian ini ditinjau bangunan 8 lantai pada lokasi gempa di Jakarta dengan tanah lunak yang dirancang sebagai sistem ganda dengan faktor reduksi R = 6,5 (SRPMM). Simulasi numerik dengan analisis pushover menunjukkan bahwa pendekatan struktur portal dengan memperhitungkan keberadaan boundary element dari dinding geser menghasilkan kinerja struktur yang paling baik dan yang paling mendekati dengan asumsi desain dibandingkan dengan 2 metode lainnya.

This thesis discussed about method of design of a reinforced concrete shear wall - frame structure as dual system due to earthquake load using pushover analysis. The purpose of using dual system structure is to produce an efficient and effective design in the planning of earthquake resistant buildings. In determining dual system structure based on Indonesia Building Code, some methods of design such as frame structure by considering the existence of boundary element of shear wall, frame structure with modification set modifiers of shear wall, and interaction of shear wall - frame structure with enlargement of story shears based on scale factor of base shear.

In this thesis an 8-story building located in Jakarta and built on soft soil was designed as dual system with reduction factor R = 6,5 (IMRF). Numerical simulations using pushover analysis show that frame structure by considering the existence of boundary element of shear wall approach results the best performance and the most closely with the design assumptions compared with other methods."
