Aminah, Siti (2017) Optimasi N-Amino Dan Total Padatan Terlarut Dalam Ekstrak Cacing Tanah (Lumbricus Rubellus) Kajian Faktor Waktu Inkubasi Dan Persentase Bahan Dasar. Sarjana thesis, Universitas Brawijaya.
Abstract
Cacing tanah merupakan hewan invertebrata yang memiliki kandungan terbesar berupa protein (64-76%). Pada tahun 2010, diketahui jumlah produksi cacing tanah di Indonesia sekitar puluhan ton. Di Indonesia pemanfaatan cacing tanah masih sebatas sebagai pakan ternak, obat, kosmetik, penghasil pupuk organik, dan makanan konsumsi manusia. Padahal diketahui bahwa protein cacing tanah memiliki daya antibakteri. Maka diperlukan penelitian untuk mendapatkan ekstrak protein melalui pelarutan anaerob. Beberapa faktor yang mempengaruhi pelarutan protein secara anaerob adalah lama waktu inkubasi dan persentase bahan dasar cacing tanah. Penelitian ini menggunakan Response Surface Methods (RSM) sebagai alat bantu untuk membuat rancangan desainnya. Rancangan model RSM tersebut menggunakan tiga belas model dan dua faktor yaitu lama inkubasi (2, 4, dan 6 hari) dan persentase bahan dasar (10, 15, dan 20%). Respon yang digunakan ialah N-amino dan Total Padatan Terlarut (TPT). Penelitian dimulai dari proses pembuatan larutan cacing tanah kemudian inkubasi dan pengujian titrasi formol dan TPT. Data hasil pengujian selanjutnya di masukkan ke dalam RSM kemudian hasilnya dianalisis. Hasil RSM menunjukkan lama waktu inkubasi 2 hari dan persentase bahan dasar (cacing tanah) 15% menghasilkan respon optimal yaitu N-amino 1,09% dan TPT 4,89%. Hasil penelitian untuk validasi menunjukkan respon yang berbeda dengan RSM, yaitu N-amino 1,82% dan total padatan terlarut 4,90%.
English Abstract
Earthworms are invertebrates that have a protein content (64- 76%). In 2010, earthworms production in Indonesia is about tens of tons. In Indonesia, earthworms processed only for several product there are as animal feed, medicine, cosmetics, organic fertilizer, and food human consumption. Even though protein in earthworm is known have antibacterial ability. Therefore, it is need a research to get a protein extract with anaerobic dissolution. Several factors that influencing dissolution anaerobic protein are long incubation period and the percentage of earthworm juice. This study uses a Response Surface Method (RSM) as a tool to create a draft design. The RSM model design using 13 models and two-factor are incubation time (2, 4, and 6 days) and the percentage of earthorms juice (10, 15, and 20%). Response used are N-amino and Total Soluble Solids (TSS). The study starts by making earthworms solution then incubation and testing formol titration and TSS. The data result from subsequent test use for RSM model and then data aanalyses. RSM’s results showed incubation time is 2 days and the percentage of earthworms is 15% produce the optimal response are 1.09% N-amino and 4.89% TSS. The results of the validation study showed a different response with the RSM, there are 1.82% N-amino and 4.90% total soluble solids.
