Abstrak: Land transportation network system consists of road and bridge, both of them has important role in connecting each region, in addition to support the transportation activity inside. Bogor city government had planned construction of Elevated Toll Road, Bogor Outer Ring Road (BORR) Section IIA on Kedunghalang – Kedungbadak roads to reduce the congestion occurs in that region currenly. The constructin concept is segmental bridge and precast segmental box girder as main component, construction method which used is “span by span erection with launching gantry”. The purpose of this research is to analyze the stress-strain and displacement that occurs on top of structre when the construction stage takes place. The methods of this research are collecting data, modelling in CSI Bridge V15, and analysis of stress-strain distribution. During the construction process, the entire structure of the box girder and column are secure against stress and compressive strain, but with the addititonal condition which is most of box girder structure and all of column structure is unsafe to stress and tensile strain. Compressive stress, tensile stress, compressive strain and tensile strain that occurs in span 2 of box girder (76 614 mm distance) after the construction steps are finished is represents respectively 2122.39 kN/m2, 3412.96 kN/m2, 7.01E-05, and 1.13E-04. In addition, the compressive stress, tensile stress, compressive strain and tensile strain that occurs in column 2 side A after constructions work is finished, the results gained are presented continously as 3632.5 kN/m2, 5708 kN/m2, 1.2E-04, and 1.89E-04, while on the B side are 4570.5 kN/m2, 7176.2 kN/m2, 1.51E-04 and 2.37E-04. The maximum deflection occurs at step 11 and 12 is in the amount of 16.7 mm, these results indicate that the structure of bridges / fly-over is stiff and safe.Obtained maximum deflection is 16.7 mm, the results show that the structure of the bridge/ fly-over is safe.

Abstrak: Flyovers is one relevant solution to overcome traffic jam is often the case in big cities. flyovers BORR section IIA (Kedunghalang-Kedungbadak) P6-P12 span is the object of research the analysis of structures against earthquake loads are analyzed by modeling the CSI Bridge v.15 with secondary data obtained from the prime contractor and refer to such regulations RSNI T-02-2005, RSNI T-12-2004, SNI 03-1725-1989, SNI 2833-2008, RSNI 03-1726-2010 dan Peta Zonasi Gempa Indonesia 2010. This research was conducted in March-May 2014 in the Department of Civil and Environmental Engineering, Bogor Agricultural University and aims to analyze the bridge structure against earthquakes. Based on the result of this research, is obtained that bridge structure are safed under earthquake loads that is ϕMn = 23003.18 kNm ≥ Mu = 19768.5094 kNm, ϕVn = 4418.796 kN ≥ Vu = 4418.796 kN and ϕTc = 60851.21 kNm ≥ 𝑇��������𝑢�������� = 46688. 56 kNm. The value of flexural, shear and torsional reinforcement beam and pier reinforcement in existing is safed under earthquake loads based on Peta Gempa Indonesia 2010.

Judul: Leukemia pada kucing
Abstrak: Leukemia pada kucing adalah suatu penyakit yang sangat patogen, disebabkan oleh sejenis virus. Virus ini dikenal sebagai Feline Leukemia Virus atau FeLV. FeLV ini oleh beberapa ahli dikatakan hanya bersifat ganas pada hewan kucing. Penularannya bisa secara horizontal maupun congenital. Kucing pada semua tingkat umur dapat terserang oleh FeLV ini. Khusus pada bentuk "thymic leukemia", virus ini hanya menyerang anak-anak kucing berumur diba- wah 1 tahun. Kucing-kucing liar atau yang tidak terpeli- hara jarang sekali terinfeksi FeLV. Selain dari serangan virus FeLV itu sendiri, maka penyakit leukemia ini bisa disebabkan oleh beberapa fak- tor yang sudah ada dalam tubuh hewan dan sangat menunjang perkembangan penyakit ini, yaitu antara lain tumor, agen toksik, cedera oleh kecelakaan dan gangguan hemopoiesis. FeLV menyerang sel-sel darah dalam tubuh hewan se- hingga pembentukan darah berjalan tidak normal. Terlihat sel-sel darah yang belum dewasa sudah beredar dalam sir- kulasi darah. Bentuk dan jumlahnya tidak lagi seimbang dalam tubuh hewan kucing tersebut. Gejala klinis antara lain kekurusan, ikterus, anemia, lemah, anoreksia, dyspnoe, sulit menelan, batuk, dan membran mukosa pucat. Selain itu kelenjar pertahanan tubuh juga membengkak, kemudian terjadi hepatomegali, spleenomegali dan pembengkakan pada ginjal. Terbentuk massa tumor pada beberapa tempat. Secara biopsy pada sumsum tulang akan terlihat be- berapa perubahan. Sumsum tulang berwarna merah tua atau abu-abu. Konsistensinya lunak dan terdapat banyak sekali memproduksi sel darah putih. Melalui gambaran darah leukemia ini lebih mudah didiagnosa. Jumlah retikulosit rendah sekali. PCV 8-15%, hemoglobin menurun, sel darah putih (WBC) meningkat, lim- fosit meningkat, Alfaglobulin juga ada peningkatan, dan banyak eosinofil yang belum dewasa beredar dalam darah…dst
