Abstract

Massive amounts of mussel shell waste are generated and wasted from the aquaculture processing sectors, resulting in environmental pollution. This material contains chitosan as a valuable compound characterized as a non-toxic structural component with several food processing applications or medicinal applications. In this research, mussel shells were processed using different solvents concentrations in several stages: demineralization, deproteination, decolourization, and deacetylation. Our result showed that the C2 samples gained a high degree of deacetylation (31.8±0.21%) with low moisture and ash content and medium weight of yield. Further research is recommended to purify chitosan using various instrumentation and assess its bioactivity.

Abstract

Komoditas lobster air tawar mulai masuk Indonesia pada tahun 2000 dan dibudidayakan untuk memenuhi kebutuhan pasar udang hias, pada tahun 2003, untuk memenuhi pasar udang hias mulai beralih trend menjadi salah satu jenis udang konsumsi. Jenis Red claw ini mampu bertahan pada kisaran suhu 23-37°C. Suhu diwilayah Indonesia yang berkisar 27-32°C menyebabkan pertumbuhan lobster air tawar yang lebih baik, sehingga lebih berpotensi untuk dibudidayakan. Sifat kanibal adalah penyebab utama mortalitas pada budidaya dan sering terjadi ketika lobster lain mengalami moulting. Pada habitat aslinya lobster menempati sela-sela bebatuan dan membuat lubang pada dasar perairan yang berlumpur untuk bersembunyi. Dalam budidaya diperlukan lubang atau liang persembunyian buatan dengan tujuan yang sama. Penempatan shelter atau liang perlindungan berguna sebagai tempat persembunyian. Pada awal segmen pembesaran, lobster air tawar memiliki frekuensi moulting yang masih tinggi sehingga perlu adanya shelter sebagai tempat berlindung setelah moulting. Ada beberapa liang perlindungan yang berasal dari bahan yang berbeda misalnya roster dari semen, roster dari tanah liat, tumpukan genteng, daun kelapa yang ditumpuk, serta potongan pipa paralon. Metode yang digunakan adalah metode eksperimen, dengan menggunakan rancangan percobaan yaitu Rancangan Acak Lengkap (RAL) dengan 4 perlakuan, masing-masing perlakuan diulang 3 kali. Setiap wadah ditebar benih lobster ukuran 2 inch dengan kepadatan 10 ekor/wadah. Aplikasi shelter pada setiap perlakuan yaitu: A= eceng gondok, B= pipa paralon, C= batu roster, dan D= botol plastik. Berdasarkan hasil penelitian yang telah dilakukan, dapat disimpulkan bahwa perlakuan shelter yang berbeda hanya menunjukkan perbedaan nyata pada variabel pertumbuhan panjang total , dengan angka tertinggi 0,36 cm pada perlakuan C (Batu roster) dan terendah dengan angka 0,23 cm pada perlakuan D (Botol plastik). Sedangkan variabel bobot mutlak, laju pertumbuhan harian, dan kelangsungan hidup tidak memperlihatkan perbedaan nyata pada semua perlakuan.
