Pemanfaatan Ampas Kelapa Hasil Fermentasi Cairan Rumen Dalam Pakan Buatan Terhadap Pertumbuhan dan Sintasan Ikan Nila (Oreochromis Niloticus)

Abstract

Tujuan penelitian ini adalah untuk megetahui pemanfaatan ampas kelapa yang difermentasi cairan rumen dalam pakan terhadap pertumbuhan ikan nila. Penelitian ini dilakasanakan pada bulan September sampai Oktober 2022 di Balai Benih Ikan (BBI) Bontomanai Kecamatan Bontomarannu Kabupaten Gowa, Sulawesi Selatan. Alat dan bahan yang digunakan adalah Rancagan Acak Lengkap (RAL) dengan 4 perlakuan 3 ulagan. Perlakuan A Cairan Rumen (40 ml), Perlakuan B (60 ml), Perlakuan C (80 ml), Perlakuan D (100 ml). Berdasarkan hasil penelitian dapat dilihat bahwa perlakuan dengan kadar ampas kelapa hasil fermentasi cairan rumen yang berbeda dalam pakan diperoleh rata-rata laju pertumbuhan tertinggi pada perlakuan C (80ml) sebesar 3.465, disusul perlakuan B (60ml) sebesar 2.36%, kemudian perlakuan A (40 ml) sebesar 1.68%, dan terendah pada perlakuan D (100ml) sebesar 1.57%. Selanjutnya hasil analisis sidik ragam menunjukkan bahwa perlakuan dengan penambahan kadar ampas kelapa hasil fermentasi cairan rumen tidak berpengaruh nyata (p> 0,05) terhadap laju pertumbuhan benih ikan nila. Hasil analisis ragam ANOVA menunjukan bahwa perlakuan dengan penambahan ampas kelapa hasil fermentasi cairan rumen dalam pakan dengan kadar yang berbeda tidak berpegaruh nyata (p>0,05) terhadap sintasan benih ikan nila. The purpose of this study was to find out the use of fermented coconut dregs in rumen fluid in feed for the growth of tilapia. This research was carried out from September to October 2022 at the Bontomanai Fish Seed Center (BBI), Bontomarannu District, Gowa Regency, South Sulawesi, the tools and materials used is a Completely Randomized Design (CRD) with 4 treatments 3 replications. Treatment A Rumen Fluid (40ml), Treatment B (60ml), Treatment C (80ml), Treatment D (100ml). Based on the results of the study it can be seen that the treatment with different levels of coconut dregs fermented rumen fluid in the feed obtained the highest average growth rate in treatment C (80ml) of 3.465, followed by treatment B (60ml) of 2.36%, then treatment A (40ml)) of 1.68%, and the lowest was in treatment D (100ml) of 1.57%. Furthermore, the results of the analysis of variance showed that treatment with the addition of coconut dregs from fermented rumen liquid had no significant effect (p> 0.05) on the growth rate of tilapia fry. The results of ANOVA analysis of variance showed that treatment with the addition of coconut dregs fermented rumen fluid in feed with different levels had no significant effect (p>0.05) on survival of tilapia fry.
