| dc.description.abstract | 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. | en |
