Abstrak: The objective of this experiment was to evaluate addition of forger by measuring physical properties of materials with addition of corn corb flour. Corn corb mixed with rice bran by different levels 0%, 5%, 10%, 15%, and 20%. This design used complete random design (CRD) with 5 treatments and 3 replications. The data analyzed by ANOVA and if there were differences continued by orthogonal contrast test. The results showed the addition of corn corb flour significantly decreased (P<0.01) specific density (kg l-1) of 1.36, 1.32, 1.26, 1.20, and 1.16 (r = 93%), bulk density (g l-1) of 286.53, 283.02, 275.74, 268.35, and 263.86 (r = 98%), compacted bulk density (g l-1) of 475.44, 463.69, 453.18, 443.14, and 433.53 (r = 99%), angle of repose (o) of 44.40, 43.91, 43.27, 43.15, and 42.70 (r = 93%), and increased particle size (mm) of 1.22, 1.23, 1.23, 1.24, and 1.25 (r = 95.8%). As conclusion, the fifth parameters could be used to detected forgery and based on the correlation, compacted bulk density was the most correct measurement.

Abstrak: The objective of this research was to evaluate the physical properties of forgery rice bran with the addition peanut hull flour levels. This research was designed by Completely Randomize Design with 5 treatments i.e P0 (100% rice bran), P1 (95% rice bran + 5% peanut hull flour), P2 (90% rice bran + 10% peanut hull flour), P3 (85% rice bran + 15% peanut hull flour) and P4 (80% rice bran + 20% peanut hull flour) and 3 replications. Data were analyzed by the analysis of variance (ANOVA) and any significant results were futher analyzed by contrast orthogonal test. The addition of peanut hull flour 0%, 5%, 10%, 15% and 20% on treatment showed a significant influence (P<0.01) in a decrease specific gravity (1.21 kg l-1, 1.19 kg l-1, 1.18 kg l-1, 1.17 kg l-1 and 1.16 kg l-1), bulk density (340.52 g l-1, 332.96 g l-1, 323.98 g l-1, 316.46 g l-1 and 308.01 g l-1), compacted bulk density (525.40 g l-1, 514.58 g l-1, 498.35 g l-1, 487.02 g l-1 and 473.94 g l-1), and angle of repose (41.60o, 41.12o, 40.69o, 40.40o and 39.91o). The bulk density has the highest correlation value (r = 99.69%) compared the other physical properties.

Judul: Infectious laryngo tracheitis pada unggas
Abstrak: Infectious Laryngo Tracheitis merupakan penyakit pada unggas yang disebabkan oleh virus yang mempunyai sasaran saluran pernapasan bagian atas Penyebab penyakit Infectious Laryngo Tracheitis Univers (ILT) adalah virus yang termasuk kelompok virus Herpes sering disebut Tarpeia avium. Virus tersebut tersusun dari inti asam deoksi ribonukleat yang dilengkapi dengan pembung- kus yang merupakan derivat dari lemak serta mempunyai garis tengah antara 195-250 nano meter. Pada temperatur kamar virus tersebut dapat bertahan selama 15 hari dalam keadaan tanpa pengawetan. Virus penyebab Infectious Laryngo Tracheitis mempunyai kepekaan terhadap zat kimia golongan pelarut lemak seperti: phenol dan kresol. Induk semang definitip penyakit Infectious Laryngo Tracheitis adalah ayam, tetapi burung merak, itik dan kalkun pernah dilaporkan dapat terinfeksi. Mammalia dan golongan rodensia merupakan hewan yang tahan terhadap infeksi penyakit ini. Pada manusia penyakit Infectious Laryngo Tracheitis diduga mempunyai hubungan dengan timbulnya gangguan neuralgia yang bersifat sub-akut akibat infeksi virus Herpes jenis lain yang disebut virus Sub-acute Myelo Optico Neuropathi (virus SMON).
