Abstrak

Penelitian dilaksanakan di Laboratorium Budidaya Perikanan, Universitas Lampung pada bulan Mei-Juli 2018. Penelitian ini bertujuan untuk mengetahui pengaruh substitusi tepung ikan dengan tepung kepala patin terhadap per-tumbuhan ikan lele, dan untuk mengetahui proporsi tepung kepala patin yang paling baik untuk pertumbuhan ikan lele. Penelitian menggunakan Rancangan Acak Lengkap dengan 3 perlakuan dan 3 kali ulangan A (tepung ikan 100%), B (tepung ikan 70% dan tepung kepala patin 30%), dan C (tepung ikan 40% dan tepung kepala patin 60%). Parameter yang diamati berupa: pertumbuhan berat mutlak, laju pertumbuhan harian, retensi protein, feed convertion ratio (FCR), survival rate (SR), dan parameter pendukung yaitu biaya pakan dan kualitas air. Data yang diperoleh dianalisis ragam dan dilanjutkan dengan uji beda nyata ter-kecil (BNT) dengan selang kepercayaan 95%. Hasil penelitian menunjukkan bahwa proporsi tepung kepala ikan patin dalam pakan buatan berpengaruh ter-hadap pertumbuhan berat mutlak dan laju pertumbuhan harian (P, 0,001). Pro-porsi penggunaan 30% tepung kepala patin dalam pakan memberikan pengaruh nyata terhadap pertumbuhan mutlak (40,25±5,67 g), dan laju pertumbuhan harian (0,67±0,09 g/hari). Kata kunci : Ikan lele, limbah kepala patin, substitusi, pakan, pertumbuhan THE EFFECT OF SUBSTITUTION OF FISH MEAL WITH PATIN FISH HEAD MEAL (Pangasius sp) ON THE GROWTH OF CATFISH (Clarias sp) The research was conducted at the Aquaculture Laboratory, University of Lampung in May to July, 2018. The aim of this study is to determine the effect of substitution of fish meal with catfish head flour on the growth of catfish, and head flour dosage the best for catfish growth. The study used a Completely Randomized Design with 3 treatments and 3 replications A (100% fish meal), B (70% fish meal and 30% catfish flour), and C (40% fish meal and 60% catfish flour). Parameters observed included absolute growth, daily growth rate, protein retention, feed convertion ratio (FCR), survival rate (SR), and supporting para-meters that is feed cost and water quality. The data obtained were analyzed by variance and continued with smallest real difference test with a 95% confidence level. The results showed that the proportion of catfish head flour in artificial feed had an effect on absolute weight growth and daily growth rate (P, 0.001). The pro-portion of the use of 30% starch in the feed of catfish has a real influence on absolute growth (40.25 ± 5.67 g), and daily growth rate (0.67 ± 0.09 g/day).
