Judul: Gambaran Histopatologi Organ Hati dan Ginjal Ayam Broiler yang Ditantang Virus Avian Influenza setelah Pemberian Ekstrak Etanol Adas Bintang (Illicium verum)
Abstrak: The aim of this research were to study the potency of star anise and histopathology of chicken’s liver and kidney that were challenged by Avian Influenza virus subtype H5N1 after treatment with star anise (Illicium verum). The research used broiler that were divided into four groups: included K1 (positive control) that were challenged by Avian Influenza virus, K2 (negative control) that were without any treatment, P1 that were challenged by virus H5N1 and extract treatment, and P2 were the group that treated by extract star anise. Chicken was fed by extract star anise from 7 to 28 days age and were challenged by H5N1 virus intranasal with dose 104 EID50/0,1 ml/chicken. Statistical analysis using Kruskal Wallis’s test then continued by Dunn’s test showed significantly different (p<0,05) between K1 with K2, P1, and P2 for liver and showed between K1 with K2 and P2 in kidney. According to mortality rate, star anise in single treatment showed capability to reduce mortality rate 37,5%. Histopathological finding of both organ showed lesions such as congestion, degeneration, hemorrhage, infiltration of inflammatory cells, and necrosis. Treatment with star anise extract decrease lesion compare among group that were challenged by virus H5N1 and extract treatment with negative control group.

Judul: Kajian histopatologi organ trakhea dan paru-paru ayam broiler yang ditantang virus Avian Influenza setelah pemberian ekstrak adas bintang (Illicium verum)
Abstrak: Penelitian ini bertujuan untuk mengetahui gambaran histopatologi organ trakhea dan paru-paru ayam yang ditantang virus Avian Influenza (AI) H5N1 setelah pemberian ekstrak adas bintang (Illicium verum). Penelitian ini menggunakan 14 ekor ayam broiler strain Cobb dibagi menjadi 4 kelompok perlakuan, yaitu kelompok kontrol positif (KP) yang tidak diberi adas bintang namun diuji tantang AI, kontrol negatif (KN) yang tidak diberi adas bintang dan tidak ditantang AI, perlakuan 1 yang diberi adas bintang dan tidak diuji tantang AI (P1), dan perlakuan 2 yang diberi adas bintang dan diuji tantang AI (P2). Hasil penelitian ini menunjukkan perbedaan yang nyata antara lesio histopatologi trakhea kelompok KP, P1 dan KN. Sebaliknya, lesio histopatologi paru-paru kelompok KP dan P2 juga berbeda nyata dengan paru-paru KN. Dapat disimpulkan bahwa bahan aktif pada ekstrak adas bintang 1 ml/hari per ekor selama 3 minggu dapat mengurangi kerusakan organ trakhea dan paru-paru akibat ditantang virus Avian Influenza H5N1 dengan dosis 104,0 EID50/0,1 ml per ekor.

Judul: Pengukuran Kecepatan Gelombang Seismik Laut 2D menggunakan Prestack Time Migration dengan Metode Kirchhoff
Abstrak: Seismic method is a method used in geophysics to study the structure of earth surface and below using sounds. Seismic waves are emitted by the transmitter into the sea to the subsurface ocean floor. Reflected wave is returned subbottom to the hydrophone and contains information on the elastic parameters of the subbottom. The method used in this study is using the Prestack Time Migration (PSTM) with the Kirchhoff method has the advantage to increase the Signal/Noise data and be able to improve data quality including time, angles, and distances. This study was conducted to analyze the speed of default parameters and the root mean square (rms) using Prestack Kirchhoff Time Migration method. Cross-sectional results of the two treatments were applied in seismic data line 13-1 in the Gulf of Bone waters, South Sulawesi. In the seismic section are sequence boundaries of toplap, downlap, normal and reverse faults event. Based on the results obtained, cross prestack time migration using the rms velocity analysis (picking velocity) gives better results compare to the cross section of prestack time migration using default parameters.
