Abstract
Pakan merupakan faktor penting dalam kegiatan budidaya ikan secara intensif. Penggunaan Lemna minor sebagai bahan baku pakan karena mudah didapat dan mengandung nutrisi yang baik. Adanya kandungan serat yang tinggi pada Lemna minor sehingga sulit untuk dicerna dan memerlukan proses fermentasi. Penelitian ini bertujuan untuk mengetahui pemanfaatan pakan tepung Lemna minor fermentasi terhadap pertumbuhan ikan bawal. Metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan, terdiri dari A tanpa tepung Lemna minor fermentasi, B tepung Lemna minor fermentasi 10%, C tepung Lemna minor fermentasi 20% dan D tepung Lemna minor fermentasi 30%. Data yang diamati yaitu jumlah konsumsi pakan (JKP), efisiensi pemanfaatan pakan (EPP), Laju pertumbuhan relatif (RGR) dan sintasan. Hasil menunjukkan bahwa perlakuan C (tepung Lemna minor fermentasi 20%) mampu menghasilkan rata-rata JKP sebesar 287,33 g, EPP sebesar 0,052%, RGR sebesar 0,090%/hari dan SR sebesar 100%Feed is an important factor in intensive fish aquaculture activities. Use Lemna minor as a feed raw material because it is easily available and contains good nutrition. The composition of high fiber in Lemna makes it difficult to digest and requires a fermentation process. This study aims to learn how to use Lemna fermentation flour on the growth of pomfret. Method used was completely randomiza design with 4 treatments and 3 replications, consisting of A without Lemna flour fermented, B Lemna flour fermented 10%, C Lemna flour 20% fermentation and D Lemna flour 30% fermentation. Interesting data are the amount of feed consumption, increased feed efficiency (EPP), relative growth rate (RGR) and survival rate. The results showed that the treatment of C (Lemna minor flour fermentation of 20%) was able to produce an average JKP of 287.33 g, EPP of 0.052%, RGR of 0.090%/day and SR of 100%
