Penelitian ini bertujuan untuk mengetahui pengaruh berat potong dan harga pembelian domba dan kambing terhadap gross margin jagal di RPH Mentik Kresen Bantul. Penelitian dilaksanakan dari 14 Mei sampai 24 Agustus 2009 dengan obyek penelitian aktivitas produksi jagal domba dan kambing lokal betina. Sampel yang digunakan adalah ternak domba dan kambing betina lokal masingmasing 60 ekor. Sampel dibagi masing-masing 30 ekor dalam berat potong 10 sampai14,99 kg (BP1) dan berat potong 15 sampai 20 kg (BP2). Data yang diambil adalah harga beli, berat potong, biaya variabel, produksi karkas-nonkarkas dan gross margin jagal. Uji faktorial digunakan untuk mengetahui perbedaan antara jenis ternak dan kelompok berat hidup mana yang paling baik untuk produksi per ekor domba dan kambing. Analisis regresi linier berganda untuk mengetahui pengaruh harga beli dan berat potong terhadap produksi domba dan kambing, serta berat potong dan biaya variabel terhadap gross margin jagal domba dan kambing. Hasil penelitian menunjukkan kambing Bligon betina dengan berat potong 15-20 kg menghasilkan produksi dan gross margin yang paling tinggi yaitu sebesar 9,83 kg dan Rp.104901,50. Harga beli dan berat potong secara signifikan dan positif berpengaruh terhadap produksi domba dan kambing lokal betina dengan R2=0,718. Terdapat perbedaan produksi pada domba dan kambing. Produksi kambing lebih baik dari produksi domba. Berat potong secara signifikan dan positif berpengaruh terhadap gross margin jagal. Biaya variabel secara signifikan dan negatif berpengaruh terhadap gross margin jagal dengan R2=0,665. Semakin tinggi biaya variabel akan menurunkan gross margin jagal. Terdapat perbedaan gross margin domba dan kambing. Gross margin kambing lebih baik dari gross margin domba. Berdasarkan hasil penelitian dapat disimpulkan bahwa produksi dan gross margin kambing betina lebih baik dari domba betina.

This study was aimed to determine the effect of slaughter weight and purchase price of female sheep and goats on the butcher’s gross margins at the slaughterhouse of Mentik, Kresen, Bantul. The study was conducted from May 14 until August 24, 2009 with the object of research was production activities of butchers. Sixty head of local female sheep and goats espectively, were used as sample. It was divided into two groups, based on its body weight, namely 10 to 14.99 kg (BP1) and 15 to 20 kg (BP2) of body weight. The data consist of purchase price, slaughter weight, variable cost, dressing and non carcass percentages and the butcher’s gross margin. Factorial test was used to determine the ratio between spesies and groups which live weight is best for the production of sheep and female goats. Multiple linear regression analysis was used to determine the effect of slaughter weight and purchase price to production of female sheep and goats, and slaughter weight and variable costs to gross margin of sheep and female goats butchers. The results showed that Bligon female goats of 15-20 kg body weight has the highest value on production and gross margins, it was 9.83 kg and Rp.104901.50, respectively. The purchase price and the slaughter weight significantly and positively affecting the production of female local sheep and goats with R2 = 0.718, female goats has better production than sheep. Slaughter weight significantly and positively affecting the gross margin of the butcher. Variable costs significantly and negatively affecting the gross margins of the butcher with R2=0.665. Higher variable cost will reduce the butcher’s gross margin. There were differences in the gross margin of female sheep and goat. The Gross margin of female goats was better than the gross margins of sheep. Based on the result, It can be concluded that local female goat’s production and gross margin was better than sheep.
