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 purpose of this study was to evaluate the changes in the physical properties of rice bran as a result of the addition of sawdust. Sawdust mixed with rice bran by different levels of 0%, 5%, 10%, 15% and 20%. The design used was CRD (completely randomized design) with 5 treatments and 3 replications. Data analysis was performed by analysis of variance (ANOVA) followed by orthogonal contrast test. The addition of sawdust in the treatment in affecting the physical properties of rice bran. Value of the physical properties of rice bran were specific gravity (kg l-1) amounted to 1.33, 1.31, 1.29, 1.27 and 1.24 (r = 98.59%), bulk density (g l-1) amounted to 275.27, 267.38, 259.55, 251.26 and 243.13 (r = 97.97%), compacted bulk density (g l-1) amounted to 432.30, 420.19, 405.08, 393.29 and 385.61 (r = 98.64% ), angle of repose (°) were 39.90, 39.68, 39.35, 39.15 and 38.95 (r = 98.28%). All of physical properties can be used to detect forgeries, but based on the results of the correlation, compacted bulk density had the highest closeness of the relationship. This results showed that compacted bulk density was the best indicator to detect forgeries.

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).
