PENGARUH PENAMBAHAN FERMENTASI TEPUNG DAUN SINGKONG MELALUI PAKAN TERHADAP PERTUMBUHAN IKAN MAS CYPRINUS CARPIO

Abstract

Harga pakan buatan relatif mahal sehingga perlu dicari alternatif pembuatan pakan buatan yang murah dan berkualitas baik. Daun adalah salah satu bahan pakan alternatif untuk pakan ikan yang memiliki kandungan serat kasar cukup tinggi dan perlu difermentasi untuk menurunkan kandungan serat kasar tersebut. Penelitian ini bertujuan untuk menentukan dosis terbaik tepung daun singkong terfermentasi dalam pakan buatan terhadap produksi ikan mas melalui kajian kelangsungan hidup dan pertumbuhan. Penelitian ini menggunakan rancangan acak lengkap dengan 3 perlakuan dan 3 ulangan yakni pakan komersial tanpa penambahan fermentasi tepung daun singkong, penambahan fermentasi tepung daun singkong 10%, dan penambahan fermentasi tepung daun singkong 17%. Ikan yang digunakan adalah ikan mas ukuran 10 g dengan panjang 8–10 cm. Wadah unit percobaan berupa waring berukuran 2 × 1 × 1 m3 yang ditancapkan pada kolam tanah berukuran 40 × 5 × 1 m3 dengan ketinggian air 80 cm. Hasil penelitian menyatakan penambahan tepung daun singkong terfermentasi pada pakan memberikan pengaruh terhadap kelangsungan hidup, pertumbuhan spesifik, dan pertumbuhan mutlak. Hasil terbaik didapatkan pada perlakuan penambahan tepung daun singkong terfementasi 10%.

The price of artificial feed is relatively expensive so it is necessary to find an alternative to make cheap and good quality artificial feed. Leaves are one of the alternative feed ingredients for fish feed that have a fairly high crude fiber content and need to be fermented to reduce the crude fiber content. This study aims to determine the best dose of fermented cassava leaf flour in artificial feed on carp production through a study of survival and growth. This study used a completely randomized design with 3 treatments and 3 replications, namely commercial feed without the addition of fermented cassava leaf flour, the addition of 10% fermented cassava leaf flour, and the addition of 17% fermented cassava leaf flour. The fish used were 10 g carp with a length of 8–10 cm. The experimental unit container was a net measuring 2 × 1 × 1 m3 which was attached to a 40 × 5 × 1 m3 earthen pond with a water height of 80 cm. The results of the study stated that the addition of fermented cassava leaf flour to the feed had an effect on survival, specific growth, and absolute growth. The best results were obtained by adding 10% fermented cassava leaf flour. Key words: carp Cyprinus Carpio, fermented cassava leaf flour.
