Judul: Analisis ketahanan struktur pier dan pier head P80 dan P79 terhadap gempa pada pembangunan on/off ramp barat JLNT Kampung Melayu-Tanah Abang
Abstrak: The bridge is building a unctioning passing traffic on the two ends of the broken because of the barriers in the river, channel, canals, a strait, the valley, road and rail road. The purpose of this study, the first is to conduct an analysis of the structure of project “On/Off Ramp Barat Jalan Layang Non Tol Kampung Melayu – Tanah Abang” to earthquake by knowing the value of the maximum forces on the maximum load combination. Standard load ultimit used based on RSNI and RSNI T02-2005 03-1726-2010, and Indonesia Earthquake Zonation Map 2010. The second compares the value in the maximum forces in combination with the nominal styles, particularly earthquake load. The secondary Data were analyzed using the software structure of CSI Bridge 15 based on the dimensions of the structure, the quality of the concrete, and the quality of steel mounted in the field. The quality of the concrete used for the pier is K-350, to use concrete quality pierhead K-450, while PCU girder using concrete quality K-600. Analysis of Bridge 15 CSI generate value for pierhead P80 ultimit moment of 86218.354 kNm, and for P79 is 87527.531 kNm. Ultimit moments are used to calculate the amount of reinforcement bending. Reinforcement bending on the pierhead P80 is 88D32 and 88D32 for P79. This value does match the existing reinforcement. Keywords: bridge, earthquake, pier, concrete quality, CSI Bridge 15, reinforce

Judul: Analisis Struktur Box Girder Jembatan Fly Over Rawabuaya Sisi Barat Terhadap Gempa
Abstrak: The Rawabuaya flyover bridge is the solution that is offered by the local government to overcome the traffic jam that often happens in the Rawabuaya area. It has an extremely vital function to disentangle the traffic congestion; therefore the structure must be strong in holding the on-going load, specifically the seismic load. The seismic load is dangerous to a structure because it has period that causes the structure to repeatedly shaken. If the movements happened continually, the structure will collapse ― depending on how much earthquake load that is being loaded on the structure. Therefore, it is essential to conduct an structure analytical on the earthquake resistance level of Rawabuaya flyover bridge based on the "Standar Perencanaan Ketahanan Gempa Untuk Struktur Bangunan Gedung dan Non-Gedung" RSNI 03-1726-2010 and "Peta Zonasi Gempa Indonesia 2010" to know further about the on-going deformation. This research is done thoroughly by recognizing the maximum forces in the combination of ultimate loads based on the most recent rules of encumbering, including the rules regarding the seismic load. The maximum forces in the combination of ultimate loads will then compared with the forces' nominal values, especially those that related to the seismic load. From the research, it can be concluded that the values of maximum forces in the combination of ultimate loads have the combined seismic load that works on the upper structure of box girder as well as on the structure beneath the pier of Rawabuaya flyover bridge with a maximum momentum values of 800300,80 KNm that applies to Pier P6B with the combination of the singular ultimate load, the additional dead load, the prestress load, and the “T” truck load. Impairment to the structure is bound to happen if the combination of ultimate load is forced to work continuously on the Rawabuaya flyover bridge. Meanwhile, the result of the compared maximum forces in the combination of ultimate load with the values of nominal forces indicates that the Rawabuaya flyover bridge has a large amount of seismic load with 10% difference. It means this structure can resist 90% of ultimate seismic load, which requires the usage of reinforcements on the upper structure of box girder as well as the on the structure beneath the pier to increase the concrete stress power and the tendon on the upper structure of box girder to increase the tensile of the concrete.

Abstrak: Balantiosis merupakan suatu penyakit pada manusia dan ababi yang disebabkan oleh Balantidium coli. Penyakit ini pertama kali diamati oleh Kalmsten pada tahun 1857 pada pasien yang mendrita diare, sedang balantidiosis pada babi pertama kali dilaporkan oleh Leukart pada tahun 1862. Parasit ini merupakan protozoa terbesar yang berada pada usus manusia dan babi dan salah satu Giliata yang patogen.
