Abstract

The purpose of this study was to determine the equilibrium of external genetic for the population of crossbreed chicken. Observations were made at the Poultry Production Unit Laboratory at Gorontalo State University. The focus was focused on the genetic equilibrium of the feathers covering the body, variations in coat color, calf color, and comb shape of the crossing population. Algebraic analysis (a + b = 1) was used to calculate phenotype frequencies, genes, and genes heterozygosity of feather color, feather pattern, shank color and comb shape for the cross chicken population. Analysis of genetic Equiblirium in the pattern of feather color, coat color, shank color, and comb shape in chicken populations was used the chi-square test. The genetic equilibrium for feather pattern can be achieved in the f2 generation. The f2 population found 3 feather color patterns: black, brown/light brown, and Columbia. Phenotype distribution; 9: 4: 3. The frequency of Genesis 0.157; 0.296; 0.546 and there was an increase in heterozygosity by 0.688 ± 0.121. The genetic equilibrium for comb shape is achieved in f1 and f2 generations. The genetic equilibrium for feather pattern can be achieved in the f2 generation.  The genetic equilibrium in cross-breed populations that have recessive/dominant homozygotes can be achieved in one generation while for cross-breeding chickens that have heterozygous properties, genetic equilibrium can be achieved in short generations if these traits are expressed evenly in the population.

Abstract

This study seeks to examine the impact of the implementation of managerial strategies undertaken by principals on the achieve-ment of principals' quality. This research using quantitative research and sample in this study amounted to 27 SMA Negeri in Bandung through panel data regression analysis during the 2016-2018 period. The results showed that managerial strategy signi-ficantly influenced the achievement of school quality. Managerial strategies in this study are measured into three strategies: 1) the effectiveness of school management, 2) strengthening the competence of graduates, 3) empowering teachers and staff. The effectiveness of school management strategies has a significantly positive effect on school quality outcomes, strategy of strengthen-ing the competencies of graduates and empowering teachers and staff has no significant effect on the achievement of school quality during the 2016-2018 period. As a recommendation, school prin-cipals should encourage graduate competencies through empo-wering teachers and staff to be actively involved so that school quality can be achieved.
