Abstract

Indonesia has a large potential for marine products, namely blue swimming crab. In general, only the part of the crab is processed into food, so crabs have the potential to produce shell waste. So that the use of crab shell waste can be made into chitosan which is done using two approaches, namely providing quality standard values and high selling prices. In the manufacture of chitosan consists of 3 stages, namely (1) Deproteination stage using 3.5% NaOH at 80℃; (2) Demineralization step using 1 N HCl at 30℃; (3) Deacetylation step using 60% KOH solution with the addition of NaBH4 (0.50; 0.75; 1 gram) and temperature (100℃, 110℃, 120℃) with a stirring time of 2.5 hours. From the results of the research that has been done, the best degree of deacetylation was obtained when the addition of 0.75 gram NaBH4 was 73.65% at 120℃. The characteristics of chitosan in the yield with the best 4.25% at 100℃ with the addition of 1 gram of NaBH4. The water content with the best is 5.15% at 110℃ with the addition of 0.75 gram NaBH4. And the ash content with the best is 1.747% at 120℃ with the addition of 0.75 gram NaBH4

Abstract

TPI Pasir Putih, Cilamaya Kulon merupakan salah satu penghasil rajungan (Portunus pelagicus) terbanyak di Karawang. Umumnya, hanya bagian daging rajungan yang dimanfaatkan untuk dikonsumsi, sehingga rajungan dapat menghasilkan banyak limbah pada cangkangnya. Salah satu pemanfaatan dari limbah cangkang rajungan yaitu dapat dijadikan produk kitosan yang memiliki nilai jual tinggi. Tujuan dari penelitian ini adalah untuk mengidentifikasi pengaruh variasi konsentrasi larutan kalium hidroksida (KOH) dengan persentase 50%, 60% dan 70% serta waktu pengadukan selama 1, 2 dan 4 jam pada suhu konstan 110°C terhadap derajat deasetilasi kitosan dan karakteristik kitosan yang memenuhi standar mutu kitosan yang ditetapkan. Nilai derajat deasetilasi kitosan terendah pada konsentrasi larutan KOH 50% dan waktu pengadukan 1 jam sebesar 62,94% sedangkan yang tertinggi pada konsentrasi larutan KOH 70% dan waktu pengadukan 4 jam sebesar 80,46%. Hasil analisis karakteristik kitosan telah memenuhi syarat mutu kitosan SNI No.7949(2013) yaitu kadar air (1,42%-1,99%), kadar abu (1,45%-1,49%) dan derajat deasetilasi (76,25%-80,46%).
