Tujuan penelitian ini adalah untuk mengetahui umur, bobot potong dan bobot karkas pada sapi peranakan Simmental jantan dan hubungan antara umur dengan bobot potong sapi serta antara umur dengan bobot karkas sapi. Materi penelitian adalah 66 ekor sapi peranakan Simmental jantan. Variabel yang diamati adalah umur dengan melihat gigi seri, penentuan bobot potong dengan cara penimbangan dengan timbangan digital merk Panasonic Kenko kapasitas 2000 kg, sedangkan bobot karkas yang terdiri dari 4 bagian ditimbang menggunakan timbangan gantung kapasitas maksimal 110 kg. Metode penelitian yang digunakan adalah survei dengan teknik pengambilan sampel menggunakan pendekatan purposive sampling. Analisis data menggunakan koefisien determinasi, koefisien korelasi, regresi sederhana dan analisis variansi. Hasil penelitian menunjukan bahwa rataan karakteristik kuantitatif sapi Simmental jantan untuk umur 2,9 ± 0,72 th, bobot potong 401 ± 96,28 kg, bobot karkas 419 ± 49,36 kg. Analisis variansi menunjukkan bahwa umur mempunyai hubungan yang sangat nyata (P<0,01) dengan bobot potong dan bobot karkas. Hasil analisis koefisien korelasi umur dengan bobot potong  adalah 0,772 dan hasil bobot karkas adalah 0,771. Sedangkan nilai koefisien determinasi sebesar r2 = 0,597 pada umur dengan bobot potong dan r2= 0,595 pada umur dengan bobot karkas. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa umur mempunyai korelasi positif dengan bobot potong dan bobot karkas sapi peranakan Simmental jantan.

The purpose of this reasearch was to determine the age, slaugther weight and carcass weight of crossbreed Simmental bulls, and the correlation between their age and their slaughter weight, and the correlation between their age and their carcass weight. The reasearch material was 66 crossbreed Simmental bulls. The variables were the age, which was determined by  assessing the incisor teeth, slaughter weight, which was determined by means of digital scales Panasonic Kenko with the capacity of 2000 kg, and the carcass weight, which consisted of 4 parts and was weighed using a brass hanging scale with maximum capacity of 110 kg. The method of this reasearch was purposive sampling approach to obtain  the data. The analysis of this research used the simple regression, the correlation coefficient, the determination coefficient, and an analysis of variance. The results showed that the quantitative characteristics of Simmental bulls were 2,9 ± 0,72 th for age, 401±96,28 kg for slaugther weight, 419 ± 49,36 kg for carcass weight. The partial regression test analysis showed that the age had significant correlations (P<0,01) to the slaughter weight and carcass weight. The result of the analysis of the correlation coefficient between age and slaughter weight was 0,772, while that between age and carcass weight was 0,771. The value of the coefficient of determination of age to slaugter weight was r2= 0,597, while that of age to carcass weight was r2= 0,595. Based on the results of this research, it can be concluded that the age has a positive correlation to the slaughter weight and the carcass weight of crossbreed Simmental bull.
