Judul: The Potency Test of Black Turmeric (Curcuma eroginosa Roxb.) in Broiler were Infected with H5N1 Avian Influenza Virus: Histopathology of Liver and Kidney.
Abstrak: Avian Influenza is one of the zoonotic disease which is very dangerous and not yet to be controlled optimally. The aim of this resarch was to observe the potency of black turmeric (Curcuma aeroginosa Roxb.) extract in preventing the infection of H5N1 virus through liver and kidney histopathologycal discriptions. This research used Cobb strain of Broiler which were devided into 4 groups included K1 (extract treatment), K2 (no extract treatment and no virus infection), P1 (extract treatment and virus infection), and P2 (virus infection). Black turmeric extract was given to Broiler during 3 weeks in postal system cage and then the Broiler were infected by H5N1 virus in Biosafety Laboratory level 3 facilities. The quantitative data obtained by scoring and then were analyzed by Kruskal Wallis and Dunn test. The result revealed that the death of Broiler which were treated with Curcuma aeroginosa Roxb. extract and were infected with H5N1 virus could be obstructed. The histopathological lesions such as hemorrhage, inflammatory focuse, necrose in liver, and also inflammatory focuse and necrose in kidney could be reduced.

Judul: Potensi Sambiloto, Sirih Merah, dan Adas Terhadap Virus Avian Influenza H5N1: Kajian Histopatologi, Mortalitas, dan Performa Broiler yang Tidak Divaksin
Abstrak: The objective of this research was to study the effect of Sambiloto, Sirih Merah, and Adas extract in inhibiting H5N1 avian influenza virus infection in broiler. Broiler were devided into 4 groups, each consisted of 8 chicks. Groups I, II, and III were given with herb extract (5%, 7.5%, and 10%) and control with aquadest. All groups were challenged with AI virus after being treated with herb extract. Observations were done for mortality, performans, histopathology of lymphoid organs (spleen, thymus and bursa Fabricius) and antibody titer of the chicken. The result of this study indicated that 7.5% herb extract better in its ability to inhibit mortality and reduce the damage of lymphoid organ than other treatments. Herb extract did not affect the performans of broiler.

Judul: Metode Waveform Relaxation Untuk Menyelesaikan Sistem Persamaan Diferensial Biasa Tak Linier Masalah Nilai Awal
Abstrak: dan BIB PARUHUM SILALAHI. Salah satu metode yang efisien dan akurat dalam menyelesaikan system persamaan diferensial biasa (SPDB) tak linier berukuran besar adalah Metode Wavefonn Relaxation (WR). Metode ini dapat diturunkan menjadi beberapa algoritma turunan yang dimodiflkasi. seperti algoritma WR dalam Iterasi Gauss-Jacobi dan algoritma WR dalam Iterasi Gauss-Seidel. Ide dasar Metode WR adalah menyelesaikan SPDS tak linier dengan cant membagi persamaan dalam sistem menjadi beberapa bagian dan memberikan nilai tebakan awal untuk setiap peubah dalam selang waktu t E [o,r]. Kemudian masing-masing bagian diselesaikan sebagai persamaan diferensial berukuran lebih_ sedikit dari sistem semula dan semua peubah selain peubah yang akan dicari solusinya dianggap bemilai konstan. Proses ini diulang hingga diperoleh solusi yang konvergen, yaitu maksimum selisih nilai solusi pada iterasi ke-(k+ I) dengan nilai solusi pada iterasi ke
