Efektivitas Pakan Maggot Black Soldier Fly dan Ampas Tahu terhadap Proksimat serta Kadar Asam Lemak Ikan Patin (Pangasius sp.)

Abstract

Ikan patin (Pangasius sp.) termasuk komoditas budidaya air tawar bernilai ekonomi tinggi dengan biaya pakan mencapai 60-70% dari total produksi. Maggot Black Soldier Fly (BSF) dan ampas tahu berpotensi menjadi pakan alternatif karena kandungan nutrisi tinggi. Penelitian ini bertujuan menganalisis pengaruh pakan berbasis kombinasi maggot BSF dan ampas tahu terhadap kadar proksimat dan profil asam lemak ikan patin. Metode penelitian ini meliputi preparasi tiga jenis pakan, yaitu pakan komersial (P1), pakan kombinasi maggot BSF dan ampas tahu (P2), dan pakan berbasis maggot BSF (P3) yang diberikan selama 28 hari, diikuti analisis proksimat dan profil asam lemak daging ikan. Hasil penelitian menunjukkan bahwa proksimat ikan patin P2 lebih optimal dibandingkan pakan komersial. Namun, proksimat paling optimal ditemukan pada ikan patin P3 dengan 75,13% kadar air, 7,98% lemak, 16,37% protein, 0,52% karbohidrat, dan nilai kalori sebesar 139,38 kkal. Simpulan penelitian ini adalah pakan kombinasi maggot BSF dan ampas tahu tidak efektif dalam meningkatkan proksimat dan kadar asam lemak pada ikan patin.

Catfish (Pangasius sp.) is a high-value freshwater aquaculture commodity, with feed accounting for 60–70% of total production costs. Black Soldier Fly (BSF) maggots and tofu residue have high nutritional content and the potential to serve as a more efficient and economical alternative feed. This study aims to analyze the effect of feeding a combination of BSF maggots and tofu residue on the proximate composition and fatty acid profile of catfish. The research methods included the preparation of three types of feed: commercial feed (P1), a combination of BSF maggots and tofu residue (P2), and BSF maggot-based feed (P3) given for 28 days, followed by analysis of the proximate composition and fatty acid profile of the fish flesh. The results showed that the proximate composition of catfish fed P2 was more optimal than that of commercial feed. However, the most optimal proximate composition was found in catfish fed P3, with 75.13% moisture, 7.98% fat, 16.37% protein, 0.52% carbohydrates, and a caloric value of 139.38 kcal. The conclusion of this study is that a combination of BSF maggots and tofu residue is ineffective in improving the proximate composition and fatty acid content of catfish.
