Abstract
Limbah kulit udang windu (Penaeus monodon) mengandung kitin yang sifatnya
sukar larut karena berikatan dengan senyawa lain seperti protein dan asam amino,
namun memiliki banyak manfaat dalam bidang makanan, agrikultural, obat-obatan
dan bangunan, sehingga kitin harus dibuat produk turunannya terlebih dahulu agar
pemanfaatnnya optimal. Tujuan dari penelitian ini adalah untuk mengisolasi dan
mengidentifikasi kapang yang memiliki daya kitinolitik kuat yang diisolasi dari
kulit udang windu. Tepung kulit udang diperoleh dengan pengeringan kulit udang
dengan matahari dan pengecilan ukuran, lalu dibusukkan dan dilakukan pour plate
pada tiga tingkat pengenceran 10-3, 10-4, dan 10-5, kemudian dilakukan isolasi dan
pemurnian dengan streak kuadran pada koloni yang membentuk zona ungu, lalu
isolat kapang kitinolitik yang diperoleh diuji daya kitinolitiknya dengan metode
difusi sumur. Media yang digunakan adalah acidified potato dextrose agar dengan
penambahan MgSO4 0,5%, Na2HPO4 0,5%, kitin koloidal 0,5% dan indikator
bromocresol purple 0,01%. Pada hasil pemurnian diperoleh dua isolat kapang. Uji
daya dilakukan pada tiap isolat dan diperoleh satu isolat kapang yang menunjukkan
daya kitinolitik yang paling kuat dengan ciri hifa tidak bersekat, zygospora, koloni
berwarna abu-abu dan serupa kapas, serta konidiofor yang bercabang. Selanjutnya,
isolat tersebut diidentifikasi dengan metode Polymerase Chain Reaction (PCR).
Hasil identifikasi isolat adalah Mucor circinelloides, kapang ini dapat ditemukan
pada udara dan lingkungan. / Black tiger shrimp (Penaeus monodon) shell waste contains chitin which is
insoluble in water because it’s bound with protein and amino acid. However, chitin
has many applications such as in foods, agricultural, pharmaceuticals, and
buildings, so it should be converted to its derivative to be used optimally. The
objectives in this study are isolating and identifying chitinolityc mold which shows
the strongest chitinolytic activity isolated from black tiger shrimp shell waste. The
shrimp shell powder was obtained by sun drying, and size reduction, and then it
was rotted. Pour plate method of the rotten shrimp shell powder on the level of
10-3, 10-4, and 10-5 was done, later it was isolated and purified by streak quadran
method. The media that had been used was acidified potato dextrose agar with the
addition of MgSO4 0.5%, Na2HPO4 0.5%, colloidal chitin 0.5%, and bromocresol
purple 0.01%. Two molds isolate was obtained and the test of chitinolytic activity
was run against those isolates. The strogest mold isolate characteristics are the
hyphae are not insulated, zygospore, grey colony and cotton-like colony, and also
irregular branch of conodiofor. Furthermore, that isolate was identified by
Polymerase Chain Reaction (PCR) method. Result of the PCR method showed that
the isolate is Mucor circinelloides, which was found on the air and environment in
the previous study.
