Pengaruh Penambahan Enzim Papain pada Pakan terhadap Kinerja Pertumbuhan Ikan Bawal Air Tawar (Colossoma macropomum)

Abstract

Penelitian ini bertujuan mendapatkan dosis terbaik dengan penambahan enzim papain pada pakan terhadap kinerja pertumbuhan ikan bawal air tawar (Colossoma macropomum). Penelitian menggunakan rancangan acak lengkap dengan lima perlakuan dan tiga ulangan. Perlakuan pakan yang ditambahkan enzim papain sebanyak 0, 1,5, 3, 4,5, dan 6 g kg-1 pakan. Pakan uji yang digunakan yaitu pakan komersial dibuat menggunakan metode repelleting dengan kandungan protein min 30%, lemak min 5%, serat kasar maks 8%, kadar abu maks 13% dan kadar air maks 12%. Ikan yang digunakan yaitu ikan bawal air tawar dengan bobot rata-rata 4,21±0,01 g sebanyak 10 ekor akuarium-1. Ikan dilakukan aklimatisasi selama 7 hari di wadah berukuran 100 × 50 × 45 cm, lalu ditebar di wadah pemeliharaan yang berukuran 60 × 40 × 35 cm selama 60 hari. Metode pemberian pakan secara at satiation dengan frekuensi pemberian pakan dua kali sehari pada pukul 07.00 dan 19.00 WIB. Hasil penelitian menunjukkan penambahan enzim papain menunjukkan hasil yang berbeda nyata (P<0,05) dengan dosis terbaik pada perlakuan 1,5 g kg-1 pakan.

This study aims to obtain the best dose by adding papain enzyme to the feed on the growth performance of freshwater pomfret (Colossoma macropomum). The study used a completely randomized design with five treatments and three replications. The feed treatments added papain enzyme were 0, 1,5, 3, 4,5, and 6 g kg-1 feed. The test feed used was commercial feed made using the repelleting method with a minimum protein content of 30%, minimum fat of 5%, maximum crude fiber of 8%, maximum ash content of 13% and maximum water content of 12%. The fish used were freshwater pomfret with an average weight of 4.21±0.01 g as many as 10 fish aquarium-1. The fish were acclimatized for 7 days in a container measuring 100 × 50 × 45 cm, then spread in a maintenance container measuring 60 × 40 × 35 cm for 60 days. The feeding method was at satiation with a feeding frequency of twice a day at 07.00 and 19.00 WIB. The results showed that the addition of papain enzyme showed significantly different results (P<0.05) with the best dose in the treatment of 1,5 g kg-1 feed.
