Rancangan penelitian yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL). Aspek yang diteliti adalah pengaruh Aspek yang di teliti adalah melihat laju pertumbuhan benih ikan lele dengan menggunakan kombinasi pakan yang dicampurkan dengan tepung daging gurita. Parameter yang diteliti adalah bagaimana pengaruh kombinasi penambahan tepung gurita sebagai bahan baku ikan lele, sehingga diperoleh 12&nbsp; percobaan. Perlakuan 1: Penambahan 100% pakan komersil, 0% tepung gurita Perlakuan 2 : Penambahan 98% pakan komersil, 2% tepung gurita, Perlakuan 3 : Penambahan 96% pakan komersil, 4% tepung gurita, Perlakuan 4: Penambahan 94% pakan komersil, 6% tepung gurita. Hasil penelitian menunjukan nilai laju pertumbuhan bobot mutlak pada perlakuan 4 senilai 5,44 gram, laju pertumbuhan berat spesifik senilai 2,60%, nilai laju pertumbuhan panjajng mutlak sebesar 3,30 cm, laju pertumbuhan Panjang spesifik senilai 0,81%, dan pada tingkat kelangsungan hidup tertinggi pada perlakuan 3 dan 4 sebesar 100%, nilai efisiensi pakan tertinggi pada perlakuan 4 sebesar 87,54%, dan rasio konversi pakan terendah pada perlakuan 4 senilai 1,13. Untuk hasil parameter kualitas air suhu 26,8-30,1⁰C, DO 3,6-5,2 mg/L, dan pH 7,5-8,4.</p> Fahrurozi Fahrurozi Salnida Yuniarti Lumbessy Dewi Putri Lestari Copyright (c) 2023 Journal of Fish Nutrition 2023-12-31 2023-12-31 3 2 1 12 10.29303/jfn.v3i2.3033 https://journal.unram.ac.id/index.php/jfn/article/view/3000 <p>Gouramy (Osphronemus gouramy) is one of the freshwater fishery commodities that are in great demand by the public, both by consumers and cultivators. Consumers like gouramy because it tastes delicious and tasty, while cultivators like gourami because it has a higher selling price compared to other freshwater fishery commodities. Feed is an important component in fish farming activities. Feed is a source of material and energy to support the growth and survival of fish, on the other hand feed is also the largest component of 50-70% of production costs. The purpose of this study was to determine the effect of feeding a combination of pellets and vegetable feed on the growth and survival of gouramy and to see the best type of vegetable feed. The results of the research were the results of the test parameters measured during the study, namely absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio (FCR), feed efficiency level (EPP), and survival rate (SR). As well as water quality data including the degree of acidity (pH), temperature, dissolved oxygen (DO), ammonia and alkalinity. The results of parameter measurements showed that the P4 treatment showed the best results for each parameter that had been observed. The effect of giving a combination of pellet feed and vegetable feed on gourami (Osphronemus gouremy) seed cultivation gave insignificant results on absolute weight growth, specific weight growth, absolute length growth, specific length growth, feed conversion ratio, feed efficiency level, and survival rate live gourami. Treatment 3 (a mixture of pellets and papaya leaves) gave the best results compared to other treatments.</p> Baiq Endang Adiningsih Nanda Diniarti Zaenal Abidin Copyright (c) 2024 Journal of Fish Nutrition 2024-01-03 2024-01-03 3 2 13 24 10.29303/jfn.v3i2.3000
