Abstract

Abstrak

Penelitian ini bertujuan untuk mengetahui perbedaan hasil penelitian gelatin yang diproduksi pada skala laboratorium dan skala bench serta mengetahui nilai efisiensi proses dan rendemen dalam pembuatan gelatin tulang ikan kakap merah pada skala laboratorium dan skala bench. Penelitian dilakukan dengan membuat gelatin tulang ikan kakap merah skala laboratorium dan bench, kemudian dilakukan analisa proksimat (kadar air, abu, protein, lemak) dan kekuatan gel, serta menghitung nilai efisiensi proses dan rendemen dari kedua skala tersebut. Analisa gelatin tulang ikan kakap merah skala laboratorium diperoleh nilai kadar air 4,64%, kadar protein 90,67%, kadar lemak 2,55%, kadar abu 2,14%, kekuatan gel 200,33 bloom dan rendemen 15,03%. Analisa gelatin tulang ikan kakap merah skala bench diperoleh nilai kadar air 4,28%, kadar protein 89,63%, kadar lemak 3,01%, kadar abu 3,08%, kekuatan gel 199,33 bloom dan rendemen 14,95%. Nilai efisiensi proses pada produksi gelatin tulang ikan kakap merah berturut-turut adalah proses pencucian 100%, degreasing 94,74%, pengecilan ukuran 100%, demineralisasi 94,74%, pencucian 100%, ekstraksi 89,47%, penyaringan 100%, pengeringan 92,71% dan pengecilan ukuran 100%. Nilai efisiensi rendemen yang diperoleh sebesar 86,62%.

Abstract

The purpose of this research is to know the difference results of research that produced in laboratory-scale and bench-scale and to know the value of efficiency process and yield in manufacture gelatine of red snapper’s bone on a laboratory-scale and bench-scale. Research done by making gelatine of red snapper’s bone in laboratory-scale and bench-scale, then analyzed proximate (moisture, ash, protein, fat) and strength of a gel and counting the value of efficiency process and yield. Analysis gelatine of red snapper’s bone on laboratory-scale obtained moisture content value of 4.64%, protein 90.67%, fat 2.55%, ash 2,14%, the strength of gel 200,33 bloom and yield 15,03%. Analysis gelatine red snapper’s bone on bench-scale obtained moisture content value of 4.28%, protein 89,63%, fat 3.01%, ash 3.08%, gel strength 199,33 bloom and yield 14.95%. The value of efficiency process for the production of gelatine red snapper’s bone in a row is the process of washing 100%, degreasing 94,74%, size diminution 100%, demineralisasi 94,74%, extraction 89,47%, filtering 100%, drying 92,71% and size diminution 100%. The yield efficiency values acquired for 86,62%.
