Abstrak Allah SWT memerintahkan manusia untuk mengkonsumsi makanan yang halal dan baik. Salah satu Bahan Tambahan Pangan yang perlu diperhatikan kehalalannya adalah gelatin. Gelatin yang beredar di Indonesia sebagian besar diperoleh dari impor yang kemungkinan besar berasal dari tulang atau kulit babi. Selain dari tulang babi, gelatin dapat diproduksi dari tulang hewan yang halal seperti sapi, ikan atau ayam. Penelitian ini bertujuan untuk mengetahui pengaruh lama perendaman dalam larutan asam klorida (HCl) dan variasi konsetrasi HCl terhadap produksi gelatin halal dari tulang ayam broiler. Penelitian ini dilakukan dalam dua tahap. Tahap pertama, pembuatan gelatin dengan variasi lama perendaman 12, 24, 36 dan 48 jam dalam HCl 5 %. Tahap kedua pembuatan gelatin dengan variasi konsentrasi HCl 3, 4, 5, 6 dan 7 % dengan lama perendaman optimal dari tahap sebelumnya. Karakterisasi produk gelatin dilakukan parameter uji kualitas gelatin dengan menentukan kadar air, kadar abu, derajat keasaman (pH), kekuatan gel, dan stabilitas emulsi dan kadar protein.Hasil penelitian menunjukkan bahwa lama perendaman dengan HCl pada poduksi gelatin tulang ayam broiler menghasilkan rendemen 7,89-10,21 %. Lama perendaman terbaik adalah 12 jam dengan rendemen 10,21 %, kadar air 8,00 %, kadar abu 11,50 %, dan pH  3,00. Sedangkan konsentrasi terbaik adalah 6 % yang dengan rendemen 3,68 %, kadar air 11,78 %, kadar abu 1,52 %, pH 4,78, kekuatan gel 9,8 N, stabilitas emulsi 63,39 % dan kadar protein 75,31 %. Kata kunci: gelatin halal; HCl, lama perendaman; konsentrasi: tulang ayam broiler. ABSTRACT Gelatin in Indonesia is generally obtained from imported product containing bone or pig skin. On the other hand, gelatin can be produced from halal sources such as cattle, fish or chickens. This study aims to determine the effect of curing time and HCl concentration variationon halal gelatin production from broiler chicken bone. This research was conducted in two stages.In the first stage, gelatin production with variation of curing time (12, 24, 36 and 48 hours) and in the second stage, gelatin production with variation of HCl concentration (3, 4, 5, 6 and 7%). Parameters in gelatin characterization are yield, moisture content, ash content, protein content, pH, gel strength, and emulsion stability. The results showed that the highest yield in gelatin production was 10.21% in 12 hours of curing time. Water content, ash content, and pH of the gelatin were 8.00%, 11.50%, and 3.00, respectively. Production of gelatin based on acid concentration variation gave the highest yield (1.52%) at HCl 6%. The chicken bone gelatin was analyzedwater, ash, and protein content which were 11.78%, 1.52%, and 75.31%, serially. Other parameters of the gelatin were 4.78 of pH, 412.4 g bloom of gel strength, and 63.39% of emulsion stability. Keywords: halal gelatin; HCl, curing time; acid concentration, broiler chicken bone;

<p>The purpose of this study was to determine the quality of gelatin by using raw materials bone chicken (Gallus gallus domesticus) and the Broiler chickens for differences in the concentration of acetic acid immersion process ( curing ).The method used in this study is the preparation and broiler chicken bones , isolation of gelatin with various concentration of acetic acid in the curing process , the process of hydrolysis , extraction temperature rise and gelatin with gelatin obtained include the characterization of protein , water , ash and metal.</p>The results showed the highest yield of gelatin produced from Broiler chicken bone types with acetic acid concentration of 1 % , ie 3.25%. Gelatin highest protein content of 86.27 % of the types of Broiler chicken bone with acetic acid concentration of 1.5 %. Lowest ash content of 15.7 % gelatin from bone types Broiler chicken with 1 % acetic acid concentration , and from analysis using AAS contained Cu at 0.6 % (of the type of chicken bones, acetic acid concentration of 0.5 %) and Cu metal content of 1.1 % (of the type of Broiler chicken bones, acetic acid concentration of 1 %. highest moisture content of 0.17 % gelatin from bone types Kampung chicken with 1 % acetic acid concentration
