Aprilianti, Wiragia Siin (2018) Laju pertumbuhan Ikan Bandeng (Chanos chanos) Dengan Penambahan Kepadatan Rumput Laut (Gracilaria sp.) Yang Berbeda Sebagai Fitoremediasi. Sarjana thesis, Universitas Brawijaya.
Abstract
Fitoremediasi merupakan salah satu metode yang menggunakan tumbuhan untuk menghilangkan, memindahkan, menstabilkan atau menghancurkan bahan pencemar baik berupa senyawa organik maupun anorganik. Ikan bandeng (Chanos chanos) memiliki masalah pada teknik budidaya yang masih relative sederhana dan tradisional, hal ini menyebabkan hasil produksi dan kualitas air kurang optimal. Salah satu tanaman yang terpilih sebagai agen fitoremediasi adalah rumput laut (Gracilaria sp.). Metode penelitian yang digunakan yaitu metode eksperimen dengan 4 perlakuan yaitu K (Ikan bandeng 60 ekor/ 15L tanpa rumput laut), A (Ikan bandeng 60 ekor/15 L dengan rumput laut 500 gram), B (Ikan bandeng 60 ekor/15 L dengan rumput laut 550 gram), C (Ikan bandeng 60 ekor/15 L dengan Rumput laut 600 gram) dengan 3 kali ulangan. Hasil penelitian kelulushidupan ikan bandeng (Chanos chanos) didapatkan rerata perlakuan A sebesar 80,56%, perlakuan B sebesar 73,78% dan perlakuan C sebesar 68,89%. Rerata laju pertumbuhan spesifik ikan bandeng (Chanos chanos) perlakuan A sebesar 4,41%/BB/Hari, perlakuan B sebesar 3,25%/BB/Hari dan perlakuan C sebesar 4,04%/BB/Hari. Rerata pertumbuhan bobot mutlak ikan bandeng (Chanos chanos) perlakuan A sebesar 2,09 gram, perlakuan B sebesar 1,36 gram dan perlakuan C 1,88 gram. Hasil kisaran kualitas air selama penelitian didapatkan Ammonia 0,036-0,268 mg/l, Nitrat 0,036-0,097 mg/l, Orthofosfat 0,011-0,666 mg/l, Suhu 27,76-31,08°C, DO 4,72-6,01 mg/l, Salinitas 16,56-17,11 ppt. Kesimpulan dari penelitian ini perlakuan terbaik yaitu pada perlakuan A meliputi kelulushidupan ikan bandeng 80,56%, laju pertumbuhan spesifik 4,41%/BB/Hari, dan pertumbuhan bobot mutlak 2,09 gram. Di sarankan untuk menggunakan kepadatan rumput laut (Gracilaria sp.) sebesar 500 gram untuk 60 ekor ikan bandeng.
English Abstract
Phytoremediation is one method that uses plants to remove, remove, stabilize or destroy contaminants in the form of organic or inorganic compounds. Milkfish (Chanos chanos) have a problem on cultivation techniques that are still relatively simple and traditional, this results in less optimal production and water quality. One of the plants selected as phytoremediation agent is seaweed (Gracilaria sp.). The research method used was experimental method with 4 treatments that are K (60 fish/15L milkfish without seaweed), A (60 fish/15L with 500 grams seaweed), B (60 fish/15L with 550 grams), C (60 fish/15 with 600 grams of seaweed) with 3 replications. The result survival rate of milkfish (Chanos chanos) at the average of treatments were A equal to 80.56%, treatment B equal to 73.78% and treatment C equal to 68.89%. The average of specific growth rate of milkfish (Chanos chanos) were treatment A was 4.41%/BB/day, treatment B was 3.25%/BB/day and treatment C was 4.04%/BB/day. The average of growth rate on milkfish (Chanos chanos) treatment were A was 2.09 gram, treatment B was 1,36 gram and treatment C was 1.88 gram. The results of the water quality range during the study obtained were Ammonia 0.036-0.268 mg/l, Nitrate 0.036-0.097 mg/l, Orthophosphate 0.011-0.666 mg/l, Temperature 27.76-31.08°C, DO 4.72-6.01 mg/l, Salinity 16.56-17.11 ppt. The conclusion of this research is the best treatment that is in treatment A covering survival rate of milk fish (Chanos chanos) 80.56%, specific growth rate 4.41%/BB/day, and growth rate 2.09 gram. It suggested to use seaweed (Gracilaria sp.) 500 grams/60 fish for phytoremediation.
