Abstract
PENGARUH SUBTITUSI PARSIAL TEPUNG IKAN DENGAN TEPUNG TULANG TERHADAP PERTUMBUHAN IKAN LELE SANGKURIANG (Clarias gariepinus.) Oleh Soraya Sopha Tepung Ikan (TI) merupakan bahan baku utama dalam pembuatan pakan. Tetapi ketersediaan dan tingginya harga tepung ikan tersebut menjadi kendala untuk para pembudidaya. Oleh sebab itu dibutuhkan bahan baku pakan alternatif yang dapat menggantikan sebagian dari penggunaan tepung ikan sebagai bahan baku pakan yaitu dengan menggunakan tepung tulang (TT). Penelitian ini dilakukan untuk mengetahui proporsi tepung tulang dalam pakan ikan serta untuk mengetahui pengaruh pakan buatan yang menggunakan tepung tulang terhadap performa pertumbuhan ikan lele sangkuriang. Ikan uji dipelihara dalam akuarium berukuran 60x40x40 cm dan setiap akuarium diisi ikan sebanyak 15 ekor dengan berat 1 ± 0,96 gram. Penelitian ini dilakukan selama 50 hari bertempat di laboraturium Budidaya Perikanan jurusan Budidaya Perairan Fakultas Pertanian Universitas Lampung . Penelitian ini menggunakan Rancangan Acak Lengkap dengan 5 perlakuan dan 3 ulangan yaitu A (40,65% TI + 0% TT); B (36,65% TI + 4% TT); C (32,65% TI + 8% TT); D (28,65% TI + 12% TT); E (24,65% TI + 16 TT). Data dianalisis menggunakan uji ANOVA (P>0,05) dan dilanjutkan dengan Uji Duncan. Hasil penelitian menunjukan bahwa subtitusi parsial pada pakan C (32,65% TI + 8% TT) dapat memberikan pertumbuhan berat mutlak tertinggi pada ikan lele sangkuriang sebesar 12,04 gr serta FCR sebesar 1,42. Kata kunci : Ikan lele sangkuriang, pertumbuhan berat mutlak, tepung ikan, tepung tulang. ABSTRACT THE EFFECT OF PARTIAL SUBSTITUTION OF FISH MEAL TO BONE MEAL ON CATFISH GROWTH (Clarias gariepenus) By Soraya Sopha Bone meal (TI) is the main ingredient in the manufacture of feed. But availability and high price of fish meal feed is a particular problem for the catfish farmers. Bone meal is able to substitute partially the use of fish meal as feed. This research was conducted to find out the proper proportion of bone meal in the fish meal for feed and to find out the extent of bone meal feed influence to Sangkurang catfish growth performance. Tested catfish was raised in aquariums sized 60x40x40 cm and each aquarium had 15 catfishes and each of them had 1 gram weight. This research was conducted for 50 days in laboratory of Aquaculture Department in Faculty of Agriculture of Lampung University. This research used completely randomized design with 5 treatments and 3 repetitions. They were A(40,65% TI + 0% TT); B(36,65% TI + 4% TT); C(32,65% TI + 8% TT); D(28,65% TI + 12% TT); E(24,65% TI + 16 TT). Data were analyzed with ANOVA (p<0.05) and then followed with Duncan test. The result showed that a proportion between fish and bone meal feed with partial substitution at C (80.32% TI + 19.68%) was able to provide 12.04 gr absolute highest weight growth for Sangkuriang catfish and 1.42 FCR. Keywords: Absolute weight growth, bone meal, fish meal, Sangkuriang catfish.
