Judul: Analisis Struktur Pondasi dan Jembatan pada Proyek Jalan Tol Cimanggis-Cibitung
Abstrak: Bridge is one of the most important parts of a highway. A Failure of bridge structures, especially the bottom as abutments, piers and foundations would be fatal to the bridge structure. Cimanggis-Cibitung Highway have length 25,785 km. One of the bridges that were analyzed in this study passing through Transyogi’s Road and the Cikeas river so advance planning is required in the form of a bridge as a condition for determining the height of the vertical free space on roads and bridges that crossed the river. The first step is determining Cikeas river flood discharge and water level flood return period of 50 years. Cikeas river flood discharge is 344,643 m3/s and flood water level of 2,4 m. Terms of vertical free space for a bridge across the river and over the exsisting path is 1 m and 5.1 m. The second step of determining the carrying capacity of the land of the results of SPT Test, Sondir Test and Test of Laboratories. Based on the test selected third Test returns to the carrying value of the land at the point of DB-28 was 2506,64 kN at a depth of 18 m. Based on the carrying value of the type of foundation used is pile foundation with a diameter of 80 cm, depth of 18 m, and concrete quality of K-350 so the amount of the foundation is 16 foundations in a group.

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: Berbagai jenis vaksin marek pada ayam
Abstrak: Penyakit Marek merupakan penyakit menular pada ayam yang disebabkan oleh virus herpes (DNA) ditandai dengan in filtrasi sel-sel neoplasma, pleomorf dan limfosit pada sya raf dan organ tubuh lainnya. Penyakit ini cukup menimbulkan kerugian pada peternak ayam di seluruh dunia termasuk Indonesia, untuk itu usaha pencegahan terhadap penyakit ini terus dilakukan. Vaksinasi merupakan suatu cara yang efektif untuk pencegahan penyakit Marek. dianggap paling Vaksinasi biasa- nya dilakukan di peternakan ayam pembibit diberikan pada ayam umur 1 hari. Vaksin Marek ada 4 macam yaitu: Vaksin HVT, atenuasi, avirulen dan polivalen yang merupakan cam- puran dari ketiga jenis vaksin tersebut. Kelemahan vaksin HVT, atenuasi dan avirulen adalah ku rang atau tidak efektif terhadap beberapa galur virus Marek di alam selain dipengaruhi oleh maternal antibodi dari HVT atau yang homolog. Ternyata kelemahan-kelemahan seper ti ini tidak berlaku bagi vaksin polivalen. Oleh Witter (1982) dinyatakan bahwa vaksin polivalen paling efektif di bandingkan dengan vaksin Marek tunggal. Vaksin polivalen belum dipasarkan secara meluas dan masih merupakan barang baru. Diharapkan kehadiran vaksin polivalen ini dapat menggantikan vaksin HVT yang biasa digunakan di lapangan….
