Abstract

ABSTRAK Gelatin merupakan suatu protein yang diperoleh dari hidrolisis kolagen kulit dan tulang hewan. Penggunaan gelatin sangat luas dalam bidang industri pangan, non pangan dan farmasi. Umumnya gelatin diperoleh dari tulang atau kulit hewan mamalia, seperti sapi dan babi. Hal ini yang menjadikan gelatin dari tulang ikan tenggiri sebagai bahan alternatif untuk menghasilkan gelatin halal. Penelitian ini bertujuan membuat ekstrak gelatin dari tulang ikan tenggiri dengan menggunakan larutan NaOH konsentrasi 1-5%. Parameter analisis yang diuji adalah analisis proksimat meliputi kadar air menggunakan metode thermogravimetri, kadar abu mengunakan metode drying ash, kadar nitrogen total dan kadar protein menggunakan metode Kjeldahl. Hasil penelitian diperoleh untuk kadar air sebesar 7,9568%, kadar abu 1,9444%, kadar N total 4,3356% dan kadar protein 27,097%. Dan rendemen terbanyak dari ekstrak gelatin diperoleh pada konsentrasi NaOH 5% yaitu 7,93%. Kata kunci: Gelatin, Tulang ikan tengiri, hidrolisis ABSTRACT Gelatin is protein that is obtained from hydrolise collagen of animal skin and bones. Gelatin has many benefit in food industry, nonfood industry and pharmacy industry. Most of gelatins were obtained from bone and skin mammals, such as cow and pork. So that, it makes gelatin from mackerel as alternaive material to produce halal gelatin. The objective of this research to make the extract gelatin from bone mackerel using NaOH solution concentration of 1-5%. Analysis parameters tested were the proximate analysis include moisture content, using thermogravimetri, determination of ash content ash drying methods, as well as the determination of total nitrogen and protein content is done by using the Kjeldahl method. The results obtained for the water content of 7.9568%, 1.9444% ash content, total N content of 4.3356% and 27.097% protein content. And the highest yield of gelatin extracts obtained at NaOH concentration of 5% is 7.93%.
