| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui ukuran linier tubuh dan bobot non karkas luar kambing Jawarandu betina dan mempelajari hubungan antara ukuran linier tubuh dengan bobot non karkas luar kambing Jawarandu betina. Materi penelitian yang digunakan adalah 50 ekor ternak kambing Jawarandu betina umur 6-12 bulan. Variabel yang diamati adalah panjang badan (PB), lingkar dada (LD), tinggi pundak (TP) dan bobot non karkas luar (kaki bagian metatarsus dan metacarpus, kepala, dan kulit). Metode penelitian yang digunakan adalah survei dengan teknik pengambilan sampel menggunakan pendekatan purposive sampling. Data dianalisis menggunakan korelasi dan regresi berganda. Hasil penelitian menunjukkan bahwa rata-rata ukuran linier tubuh PB sebesar 61,02 ± 6,57 cm, LD 69,30 ± 7,17 cm, dan TP 65,50 ± 5,69 cm, sedangkan bobot non karkas luar yaitu kaki bagian metacarpus dan metatarsus sebesar 0,80 ± 0,27 kg, kepala 1,76 ± 0,45 kg, dan kulit 1,93 ± 0,53 kg. Hasil analisis variansi menunjukkan bahwa panjang badan, lingkar dada, dan tinggi pundak berpengaruh nyata (P<0,05) terhadap bobot kaki bagian metacarpus dan metatarsus, kepala dan kulit dengan persamaan regresi dan koefisien determinasi masing-masing adalah, bobot kaki bagian metacarpus dan metatarsus = -1,647 + 0,013 PB + 0,024 LD dengan koefisien determinasi (r2) = 0,721 ; kepala = -2,206 + 0,030 LD + 0,029 TP dengan koefisien determinasi (r2) = 0,646 ; dan kulit = -3,400 + 0,035 PB + 0,023 LD + 0,025 TP dengan koefisien determinasi (r2) = 0,790. Penelitian dapat disimpulkan bahwa panjang badan dapat digunakan untuk memprediksi bobot kaki dan bobot kulit, lingkar dada dapat digunakan untuk memprediksi bobot kaki, kepala, dan kulit, sedangkan tinggi pundak dapat digunakan untuk memprediksi bobot kepala dan kulit kambing Jawarandu betina. |

| Abtrak (Bhs. Inggris) | The purpose of this research was to identify the linear size of body with and the weight of outer non carcass of female Jawarandu Goat and to study the relationship between the linear size of body and the weight of outer non carcass of Jawarandu goat female. The research material used was 50 of Jawarandu Goat female aged 6-12 months. The variables measured were body length (BL), chest circumference (CC), high shoulder (HS) and weight of Outer Non Carcass (metatarsus and metacarpus leg, head and skin). The reaserch method used was a survey with a purposive sampling approach to collect the data. It was analyzed with correlation and double regression. The results showed that the average size of the linear body included PB were 61.02 ± 6.57 cm, LD 69.30 ± 7.17 cm, and TP 65.50 ± 5.69 cm respectively, while the non-carcass weight which consisted of leg metacarpus and metatarsus were 0.80 ± 0.27 kg, head 1.76 ± 0.45 kg and skin 1.93 ± 0.53 kg respectively. The results of analysis showed that the body length, chest circumference, and height of shoulder had significant relation (P <0.05) to the weight of the legs metatarsus and metacarpus, heads and skins with the regression equation and the coefficient of determination, respectively, the weight of the legs metatarsus and metacarpus = -1.647 + 0.013 + 0.024 PB LD with a coefficient of determination (r2) = 0.721 ; head = -2.206 + 0.030 + 0.029 LD TP with a coefficient of determination (r2) = 0.646 ; and skin = -3.400 + 0.035 PB + LD 0,023 + 0,025 TP with a coefficient of determination (r2) = 0.790. It can be used to predict the weight of legs and skin, chest circumference can be used to predict the weight of legs, head, and skin, while the shoulder height can be used to predict the weight of head and skin of female Jawarandu Goat. |
