Judul: Strength Analysis of Bridge Structure Based on Earthquake Load (Case Study: Cisomang Bridge Pubaleunyi Toll STA 100+700)
Abstrak: Kejadian-kejadian gempa besar yang pernah terjadi di Indonesia, mengisyaratkan bahwa upaya preventif perlu dilakukan dalam perancangan struktural pada suatu jembatan. Tujuan dari penelitian ini adalah menganalisis besarnya gaya dalam maksimum pada kondisi layan dan ultimit, menghitung jumlah tulangan PCI girder dan pier column, serta menganalisis periode getar, kekakuan struktur, dan displacement yang terjadi. Penelitian menggunakan Data sekunder as built drawing jembatan berupa data gambar dan dimensi girder, deck, pier head, dan pier column serta data material Jembatan Cisomang. Metode yang digunakan adalah pemodelan dan analisis gaya dalam menggunakan software CSI Bridge ver 22. Nilai kekakuan dari struktur Jembatan Cisomang didapatkan sebesar 176.682,1 kN/m. Besarnya perpindahan yang terjadi masih dibawah nilai displacement izin sebesar 168 mm. Girder dapat menahan momen dengan jumlah tendon 21 diameter 13 mm dan tulangan lentur (162D16). Namun, jumlah tendon dan tulangan lentur tersebut tidak memenuhi syarat tulangan lentur maksimum. Tulangan eksisting pada pier column mampu menahan gaya dalam yang bekerja sehingga tidak diperlukan tambahan tulangan., Major earthquakes that have occurred in Indonesia indicate that preventive measures need to be taken in the structural design of a bridge. The purpose of this study is to analyze the maximum internal force at service and ultimate conditions, calculate the amount of PCI girder and pier column reinforcement, and analyze the period of vibration, structural stiffness, and displacement that occur. The study used secondary data as built drawing bridges in the form of drawing data and dimensions of girders, decks, pier heads, and pier columns as well as material data for the Cisomang Bridge. The method used is modeling and force analysis using CSI Bridge ver 22 software. The stiffness value of the Cisomang Bridge structure is 176,682.1 kN/m. The amount of displacement that occurs is still below the allowable displacement value of 168 mm. The girder can withstand moments with a total of 21 tendons with a diameter of 13 mm and flexural reinforcement (162D16). However, the number of tendons and flexural reinforcement does not meet the requirements for maximum flexural reinforcement. The existing reinforcement in the pier column is able to withstand the working internal forces so that no additional reinforcement is needed.

Judul: Analisis dan Desain Jembatan Frame, Kolom “V”, Box Girder, dengan Mempertimbangkan Beban Gempa
Abstrak: The growing of economic, social, cultural and environmental influenced by the availability of infrastructure, such as bridges. The bridges often used as a city icon. Selection of bridge structures important to adapt the structural strength and stability, serviceability structure, durability, ease of implementation, economic, and aesthetic. Strength of bridge structure in Indonesia is strongly influenced by earthquake load. Therefore, the construction of flyover Simpang Jam Batam needs to be built and studied. This study aims to analyze and design the frame bridge with "V"column and boxgirder, consider to earthquake load, and design reinforced concrete structures. The methods are data collection, preliminary dimension, modeling in CSI Bridge, and reinforcement design. The study started at April to July 2013 in Department of Civil and Environmental Engineering, Bogor Agricultural University. The result is the maximum forces obtained occurs in combination ULS-4a and SLS-4a, that moment values are 66298.6 kNm and 37494 kNm, whereas shear force values are 9735.71 kN and 6346.73 kN. Based on the results, boxgirder flexural reinforcement at top slab is D19-100 and D19-200, bottom slab and web are D16-150. Meanwhile, boxgirder shear reinforcement needs only at web is D16-150. Column "V" reinforcement is D25-150 to flexural and D16-150 to shear.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
