Abstract: Ayam cemani merupakan salah satu jenis ayam kedu hitam yang memiliki warna hitam diseluruh tubuhnya akibat mutasi gen fibromelanosis. Fibromelanosis ini disebabkan adanya duplikasi yang tidak seimbang pada kromosom 20 dan salah satu daerah duplikat mengandung gen EDN3. Penelitian ini bertujuan menganalisis variasi batas duplikasi pada daerah fibromelanosis pada kromosom 20 untuk mengetahui kemurnian ayam cemani. Penelitian ini menggunakan metode Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) pada 76 ekor ayam terdiri dari 32 ekor ayam cemani PT. Sumber Unggas Indonesia, 40 ekor ayam cemani Balai Penelitian Peternakan, dan 4 ekor ayam IPB-D1 sebagai pembanding. Hasil penelitian menyatakan ayam cemani memiliki alel ganda yaitu alel Fm, fm+, dan fm-. Ayam cemani (homogisot) memiliki genotipe Fm/Fm dengan dua pita pada 664 bp dan 588 bp. Ayam cemani heterosigot memiliki genotipe Fm/fm+ dengan empat pita pada 664 bp, 588 bp, 400 bp, dan 264 bp. Ayam cemani wildtype memiliki genotipe fm-/fm- dengan satu pita pada 664 bp. Ayam IPB-D1 (wildtype) memiliki dua genotipe yaitu fm+/fm- (pita 664bp,400 bp, dan 264 bp) dan fm+/fm+ (pita 400 bp dan 264 bp). Keragaman ayam cemani rendah dan besifat polimorfik. Ayam cemani SUI berada dalam keseimbangan Hardy-Weinberg kecuali pada ayam cemani Balitnak.
Cemani chicken is a type of black kedu chicken that has black color all over its body due to fibromelanosis gene mutation. Fibromelanosis is caused by an unbalanced duplication of chromosome 20 and one of the duplicated regions contains the EDN3 gene. This study aimed to analyze the variation of the duplication limit in the fibromelanosis region on chromosome 20 to determine the purity of cemani chicken. This study used the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method on 76 chickens consisting of 32 cemani chickens PT. Source of Indonesian Poultry, 40 cemani chickens from the Animal Husbandry Research Institute, and 4 IPB-D1 chickens for comparison. The results showed that cemani chickens had multiple alleles, namely Fm, fm+, and fm- alleles. Chicken cemani (homogizot) has a genotype of Fm/Fm with two bands at 664 bp and 588 bp. Heterozygous cemani chickens had Fm/fm+ genotype with four bands at 664 bp, 588 bp, 400 bp, and 264 bp. The wildtype cemani chicken had a genotype of fm-/fm- with one band at 664 bp. IPB-D1 (wildtype) chickens have two genotypes, namely fm+/fm- (bands 664bp, 400 bp, and 264 bp) and fm+/fm+ (bands 400 bp and 264 bp). The diversity of cemani chickens is low and polymorphic. Cemani SUI chickens were in Hardy-Weinberg equilibrium except for cemani Balitnak chickens.
