Kadar Protein dan Profil Asam Amino Ikan Patin (Pangasius sp.) dengan Pemberian Pakan Kombinasi Maggot Black Soldier Fly dan Ampas Tahu

Abstract

Maggot Black Soldier Fly (BSF) dan ampas tahu berpotensi digunakan sebagai pakan alternatif bernutrisi tinggi dan ekonomis. Penelitian ini bertujuan menganalisis pengaruh pakan kombinasi maggot BSF dan ampas tahu terhadap pertumbuhan, kadar protein, dan profil asam amino ikan patin. Penelitian menggunakan tiga perlakuan pakan: P1 (pakan standar), P2 (kombinasi maggot BSF dan ampas tahu), dan P3 (tepung maggot), dengan masa pemeliharaan 28 hari. Parameter yang diamati meliputi laju pertumbuhan, kadar protein terlarut, dan asam amino. Hasil penelitian menunjukkan pemberian pakan kombinasi maggot BSF dan ampas tahu tidak berpengaruh nyata terhadap length gain, body weight gain, percentage weight gain, dan specific grow rate. P2 menghasilkan kadar protein terlarut tertinggi sebesar 19,40 mg/g dan asam amino bebas 109,96 mg/g. Profil asam amino tertinggi diperoleh pada lisin (asam amino esensial) dan asam glutamat (asam amino non-esensial). Hasil ini menunjukkan bahwa kombinasi maggot BSF dan ampas tahu mampu menghasilkan pakan berkadar protein tinggi sehingga berpotensi dimanfaatkan sebagai pakan alternatif bagi ikan patin.

Black Soldier Fly (BSF) maggots and tofu residue have the potential to be used as nutritious and cost-effective alternative feeds. This study aimed to analyze the effect of a feed combination of BSF maggots and tofu residue on the growth, protein content, and amino acid profile of catfish. Three feed treatments were used: P1 (standard feed), P2 (a combination of BSF maggots and tofu residue), and P3 (maggot meal), with a rearing period of 28 days. Parameters observed included growth rate, soluble protein, and amino acids. The results showed that feeding a combination of BSF maggots and tofu residue had no significant effect on length gain, body weight gain, percentage weight gain, and specific grow rate. P2 produced the highest soluble protein (19,40 mg/g) and free amino acids (109,96 mg/g). The highest amino acid profiles were lysine (essential amino acid) and glutamic acid (non-essential amino acid). These results indicate that the combination of BSF maggots and tofu residue can produce high-protein feed and has potential as an alternative feed source for catfish.
