The eggs used in this study were 400 eggs divided by 100 Isa Brown and 100 Hyline Brown from Denai Village, Pantai Labu Subdistrict, Regency Deli Serdang, then 100 Isa Brown and 100 Hyline Brown from Sei Limbat Village, Kecamatan Selesai, Langkat District. Each egg is collected directly from the chicken and then measured against the exterior and interior. The results showed that the characterization and comparative test of chicken eggs consumption of strains of Isa Brown and Hyline Brown in different regions had results(thit> ttable) with t test on comparative test I1: H1 and I2: H2 meaning egg of different strain showed different result also on egg weight parameter, shapeegg, shell weight, air cavity, egg white index, haugh unit, egg yolk index and yolk color. The comparative test I1: I2 showed no significant differences (thit <ttabel) on egg weight, shell thickness, shell weight, egg white index, haugh unit and egg yolk index, but showed significantly different (titable) results in egg shape, air cavity and yolk color, meaning there is environmental influence but not significant to other quality of egg with same strain in different region. In the H1: H2 comparative test the results were not significantly different (thit <ttabel) on all parameters except the color of egg yolks, meaning that no environmental or strain effect produced eggs of the same quality in different regions.

Kualitas Fisik Telur Puyuh Yang Direndam Dalam Larutan Gelatin Tulang Kaki Ayam Dengan Lama Penyimpanan Yang Berbeda

Quail eggs is one of the perishable food. If left in the open air at room temperature, the shelf life ranged between 10-14 days. Preservation is one of the way to prolong shelf life which can be done by soaking the eggs in a gelatin solution. The purpose of the study was to know the physical quality of quail egg soaked in gelatin bone chicken feet long with different time of storage. The experimental design of this study was Complete Randomized Design (CRD) factorial pattern 3 x 3 with 5 replications. The first factor was soaking time (0, 30 and 60 minutes) and the second factor was storage time (0, 15 and 30 days). The results showed that there was nos ignificant effect of soaking period (P>0.05) on egg weight, egg white index, yolk index, Haugh units and pH. The longer the storage time, the egg weight, egg white index, yolk index, haugh unit were decreased and the other hand, pH value was increased. Soaking quail eggs in gelatin solution of chicken feet during 30 minutes and storage time for 15 days resulted in pH value almost the same with untreated egg(control).

Psycholinguistic Abilities of Black and White Children from Four SES Levels

The Illinois Test of Psycholinguistic Abilities, revised edition, was administered to 160 black and white children of average mental ability from the lower lower, upper lower, lower middle, and upper middle socioeconomic status (SES) levels as determined by the McGuire-White Index of Socioeconomic Status. The results indicate that the level of performance and pattern of psycholinguistic abilities of black children is relatively free of a systematic influence from SES but the performance of white children is related to socioeconomic status. The lower SES levels and black children showed more variability than the middle SES and white children. The reported lower SES visual-motor orientation and middle SES auditory-vocal orientation were not supported in this study.
