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: Penyakit kudis pada kelinci ( Scabies ) dan cara penanggulangannya
Abstrak: Salah satu penyakit yang disebabkan oleh parasit terutama ektoparasit pada kelinci yang sering dijumpai adalah penyakit kudis. Kudis merupakan penyakit kulit yang sangat menular yang disebabkan oleh beberapa jenis tungau. Beberapa jenis tungau penyebab kudis yang telah diketahui antara lain Sarcoptes scabiei, Notoedres sp. dan Psoroptes sp. Hewan umur muda, hewan tua yang dipelihara dalam kondisi jelek merupakan faktor-faktor predisposisi bagi infestasi penyakit kudis. Infeksi meluas terutama oleh kontak dengan larva, nympha dan betina yang bunting. Tungau sangat peka terhadap kekeringan dan tidak dapat hidup lama pada hostnya dalam keadaan tersebut. Dalam penyebarannya lebih menyukai bagian tubuh yang tidak ditutupi banyak bulu seperti kepala dan telinga. Gejala klinis yang ditimbulkannya antara lain hewan menampakkan rasa gatal, gelisah dan selalu menggaruk-garuk badannya, kulit merah, menebal, ada exudat, bulu rontok dan kulit menjadi gundul. Apabila kasusnya parah maka hewan bisa mengalami kekurusan, dehidrasi dan akhirnya terjadi Kematian. Diagnosa didasarkan atas gejala klinis. Selain itu untuk lebih meyakinkan diagnosa dilakukan pemeriksaan mikroskopis dari bahan kerokan kulit. Tindakan pencegahan mencakup penempatan hewan di kandang yang bersih dan hangat, memberi makan yang bergizi baik. Untuk pemberantasan populasi tungau diperlukan tindakan isolasi hewan sakit, bulu-bulu atau rambut dicukur kemudian bagian kerak-kerak yang tebal dibersihkan dengan sabun dan air hangat dan dijaga terhadap kontak dengan hewan yang sehat. Obat-obat yang sering digunakan antara lain emulsi belerang, benzyl benzoat, Lindane, Tetmosol, Coumaphos dan Ivermectin.
