Abstrak: Irrigation with closed distribution system using pipes is possible to sedimentation in the pipes, therefore is necessary to design piping system so sedimentation in the pipes can be as minimal as possible. Division box in the tertiary irrigation network is very important in addition to divide discharge proportional to the field also as a sediment control that sedimentation in the pipe to a minimum. The main objective of this research is to design division box in the PVC pipe for irrigated paddy field, so that the results will be: (1) Flow characteristics Analysis in the division box for the most optimal pipeline so that the sedimentation in the pipe to a minimum; (2) Simulation to analyze the flow of sediment and flow characteristics in the piping irrigated using surface water as a source of irrigation water, (3) the relation between the design parameters of division box with the flow based on the diameter of the inlet pipe and outlet pipes. Durst (2008 ) explains that the similarity theory of dimensional analysis is that if the differential equations that describe the flow of the problem is unknown . It is important that dimensional analysis can also be used when the physical relation between the amount of which is not known at all . Division box built in the tertiary canals and the quarter in order to divide the irrigation water to all tertiary and quarter. Models of division box was made to simulate the flow in PVC pipe and division box in the same pipeline so that the quaternary as happened in the real situation on the field . In this research made the model of division box for irrigation piping systems with the circular cross section. Analysis of flow characteristics in the division box using the method of dimensional analysis. At the phase of dimensional analysis to determine the flow characteristics in PVC pipes and division box with choosing the basic unit of the relation between derivative quantities. The graphs of the data model and the simulation results in the field validation results that can be used as a reference in designing the division box in the irrigation network that uses PVC pipe for piping irrigated. Results of this graph can be used to determine the design of division box on tertiary irrigation network optimized so as to minimize the occurrence of sedimentation in the PVC pipe.

Abstrak: Irrigation techniques provides water with the right conditions, the right space, and timely in a way that is effective, economical, and efficient. Planning and design of irrigation system refers to the contour of the land and the flow pattern of the system is needed. So it will impact in increase of productivity and quality of the harvest quality. Placement of irrigation channel adjoining the location of the farm, intended to have a higher elevation with farmland. The planning of secondary irrigation channels along the branches 4196.47 m with tertiary channels have an average 400-800 m length. With an area of 343.89 ha of agricultural land in total consisting of zone 1, 2, and three. Irrigation water requirements by using an open channel with trapezoidal cross-section and use the design method of Strickler required discharge of 0.6043 m3 / s with a coefficient of crop water 1,46 l / s / ha. The results of channel design successfully done according to the appendix 3, in cross section two secondary channels are used to accommodate the irrigation discharge of 0.6043 m3 / s, k = 35, m = 1, n = 2, b = 1,142 m, y = 0,571 m, v = 0,6 m / s, and I = 0,0012. Based on the results of modeling using HEC-RAS software 4.1 on irrigation channels can be said to be safe, and able to accommodate discharge of irrigation according to the needs of 0.6043 m3 / sec with input value n (manning roughness) of 0.025 and a efficiency of secondary channel 90% and 95% of tertiary channels.

Judul: Penapisan Hepadnavirus Secara Serologik Dan Molekuler Pada Monyet Ekor Panjang (Macaca Fascicularis) Di Habitat Ex-Situ
Abstrak: Penemuan infeksi virus hepatitis B (VHB) monyet ekor panjang (Macaca fascicularis) di Pulau Mauritius pada tahun 2013 merupakan temuan baru yang menunjukan bahwa penyakit ini dapat menginfeksi jenis satwa primata dari famili Cercopithecidae. Temuan tersebut hanya dilaporkan pada M. fascicularis yang berada di benua Afrika, sehingga menjadi alasan dilakukannya investigasi pada M. fascicularis asal Indonesia. Untuk mendapatkan gambaran keadaan tersebut, sampel darah M. fascicularis diambil dari berbagai lokasi habitat ex-situ. Uji penapisan terhadap antigen permukaan virus hepatitis B (Hepatitis B surface antigen, HBsAg) dilakukan pada 95 sampel plasma dan serum M. fascicularis yang berasal dari penangkaran, pusat penyelamatan satwa, dan topeng monyet. Upaya pemeriksaan DNA VHB dilakukan pada sampel yang menunjukan hasil seropositif terhadap HBsAg. Uji penapisan menunjukan bahwa sebanyak 11 dari 95 (11.6%) sampel reaktif terhadap HBsAg. Antigen permukaan virus hepatitis B lebih banyak ditemukan pada monyet di pusat penyelamatan satwa dan topeng monyet (55%) dibandingkan dengan satwa penangkaran (45%). Hasil seropositif HBsAg pada sampel M. fascicularis yang diperiksa dengan teknik ELISA menggunakan kit HBsAg manusia mengindikasikan adanya kemiripan protein antigen permukaan VHB manusia dengan yang ditemukan pada M. fascicularis, karena antibodi monoklonal yang digunakan dalam uji ELISA pada penelitian ini bersifat spesifik mengikat HBsAg manusia. Meskipun uji PCR terhadap sampel tersebut tidak menunjukkan adanya DNA VHB, hasil seropositif HBsAg mengindikasikan bahwa M. fascicularis dapat terinfeksi VHB atau virus yang mirip VHB secara alami.
