Penelitian yang dilaksanakan di Rumah Potong Hewan Mersi, Purwokerto, Jawa Tengah, ini bertujuan untuk 1) mengetahui bobot potong, bobot karkas dan bobot kulit, 2) mempelajari hubungan antara bobot potong dengan bobot karkas, dan 3) untuk mempelajari hubungan antara bobot potong dengan bobot kulit. Materi penelitian yang digunakan adalah 50 ekor ternak sapi Simmental jantan. Variabel yang diamati adalah bobot potong dengan menggunakan alat timbang merk “Crane Scale” berkapasitas 1000 kg dan ketelitian 0,01 kg, sedangkan bobot karkas dan bobot kulit menggunakan timbangan digital gantung merk “Excellent” dengan kapasitas 600 kg dan ketelitian 0,1 kg. Metode penelitian yang digunakan adalah survei dengan teknik pengambilan data menggunakan pendekatan purposive sampling. Analisis penelitian menggunakan koefisien determinasi, koefisien korelasi, uji ANAVA dan regresi sederhana. Hasil penelitian menunjukan bahwa karakteristik kuantitatif sapi Simmental jantan untuk bobot potong 463,8 ± 4,53 kg, bobot karkas 257,56 ± 2,98 kg, bobot kulit 46,62 ± 5,24 kg, % karkas 55,43 ± 0,39 % dan % kulit 10,07 ± 0,08 %. Hasil analisis regresi sederhana menunjukkan BKar= 6,07 + 0,54 BP dan BKul= 7,29 + 0,09 BP. ANAVA menunjukkan bahwa bobot potong mempunyai hubungan yang nyata (P<0,05) dengan bobot karkas dan bobot kulit. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa bobot potong mempunyai korelasi positif dengan bobot karkas dan bobot kulit sapi Simmental.

This research, which had been conducted at the Mersi Slaughterhouse, Purwokerto, Central Java, aims to 1) assess the slaughter, carcass, and hide weight of Simmental bulls, 2) study the correlation between their slaughter and carcass weight, and 3) measure the correlation between their slaughter and hide weight. The materials used in this research were 50 Simmental bulls. The variables were the slaughter weight, which was measured by using the “Crane Scale” scale whose capacity and degree of accuracy is, respectively, 1000 kg and 0,01 kg, and the carcass weight, which was measured by using the “Excellent” digital scale whose capacity and degree of accuracy is, respectively, 600 kg and 0,1 kg. This research used purposive sampling approach to obtain the data. The analysis of this research used the simple regression, the coefficient correlation, the coefficient determination, and ANOVA. The results shows that the quantitative characteristics of the Simmental bulls’ slaughter weight (SW) was 463,8 ± 4,53 kg, carcass weight (CW) was 257,56 ± 2,98 kg, hide weight (HW) was 46,62 ± 5,24 kg, % carcass 55,43 ± 0,39 % and % hide 10,07 ± 0,08 %. The results of the multiple regression analysis show that CW= 6,07 + 0,54 SW and HW= 7,29 + 0,09 SW. The partial regression test analysis shows that the slaughter weight has a significant correlation (P<0.05) with the carcass and leather weight. Based on the results of this research, it can be concluded that the slaughter weight has a positive correlation to the carcass and hide weight of Simmental.
