Ampas kelapa merupakan sumber nabati yang berpotensi sebagai bahan baku pakan ikan, karena memiliki kandungan galaktomanan yang berfungsi sebagai prebiotik dalam pakan. Penambahan prebiotik dalam pakan dapat mempercepat pertumbuhan. Penelitian bertujuan untuk mengetahui pertumbuhan ikan tawes dengan pemberian ekstrak ampas kelapa sebagai sumber prebiotik pada pakan. Penelitian dilaksanakan pada Mei-Juni 2023, lokasi penelitian di Laboratorium Pembenihan dan Pembiakan Ikan, Fakultas Kelautan dan Perikanan, Banda Aceh. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) dengan 5 perlakuan 4 kali ulangan. Pemberian ekstrak ampas kelapa pada pakan komersil dengan menggunakan dosis yang berbeda yaitu perlakuan A (tanpa ekstrak ampas kelapa), Perlakuan B (2%/kg pakan), perlakuan C (4%/kg), perlakuan D (6%/kg), dan perlakuan E (8%/kg). Parameter yang diukur yaitu pertumbuhan berat mutlak, panjang mutlak, laju pertumbuhan spesifik, kelangsungan hidup, rasio konversi pakan, dan kualitas air. Hasil penelitian menunjukkan bahwa pertumbuhan berat mutlak terbaik pada perlakuan D (6%/kg pakan) sebesar 27,09 g, pengukuran panjang mutlak terbaik pada perlakuan E (8%/kg) sebesar 26,47 cm, nilai efesiensi pakan D (6%) sebesar 89,38%, Feed convertion ratio terbaik pada C (4%) sebesar 1,08 dan Survival rate berkisar antara 87,5%-100%. Penambahan ekstrak ampas kelapa dalam pakan sebagai sumber prebiotik tidak memberi pengaruh signifikan antar perlakuan.

Coconut pulp is a vegetable source that has a potential as a raw material for fish feed, because it contains galactomannan which functions as a prebiotic in feed. Adding prebiotics to feed can accelerate growth. The research aims to determine the growth of tawes larvae by providing coconut dregs extract as a source of prebiotics in feed. The research was carried out in May-June 2023, the research location was at the Fish Hatchery and Breeding Laboratory.The research used a Completely Randomized Design (CRD) method with 5 treatments and 4 replications. Giving coconut pulp extract to commercial feed using different doses, namely treatment A (without coconut pulp extract), Treatment B (2%/kg feed), Treatment C (4%/kg), Treatment D (6%/kg), and treatment E (8%/kg). The parameters measured were growth in absolute weight, absolute length, specific growth rate, survival, feed conversion ratio, and water quality. The results of the research showed that the best absolute weight growth in treatment D (6%/kg feed) was 27.09 g, the best length measurement in treatment E (8%/kg) was 26.47 cm, feed efficiency value D (6%) of 89.38%, the best feed conversion ratio at C (4%) was 1.08 and the survival rate ranged from 87.5%-100%. The addition of coconut dregs extract in feed as a source of prebiotics did not have a significant effect between treatments.
