Performa Maggot Black Soldier Fly (Hermetia Illucens) pada Substrat dengan Rasio Karbohidrat Protein Berbeda

Abstract

Penelitian ini bertujuan mengevaluasi maggot yang diberi pakan dengan rasio karbohidrat protein yang berbeda. Penelitian ini menggunakan 2 perlakuan dan 5 ulangan, perlakuan substrat dengan rasio karbohidrat : protein 88%:12% (P1) dan 74%:26% (P2), substrat perlakuan diberikan sebanyak 2,25 kilogram selama pemeliharaan. Parameter performa yang diukur yaitu konsumsi bahan kering (BK), protein kasar (PK), lemak kasar (LK), serat kasar (SK) dan asam amino, bobot hidup, persentase prepupa, reduksi substrat, serta feed conversion ratio (FCR). Data dianalisis menggunakan sidik ragam T-Test (Independent Sample T-Test). Performa maggot BSF perlakuan P2 menunjukkan hasil yang nyata lebih tinggi (P<0,05) dibandingkan dengan perlakuan P1 pada parameter konsumsi BK dan PK, bobot hidup, persentase prepupa, reduksi substrat, serta FCR. Konsumsi asam amino esensial tertinggi yaitu leusin, lisin, dan threonin, sementara konsumsi asam amino nonesensial tertinggi yaitu asam glutamat, asam aspartat, dan glisin. Kesimpulannya, pemberian pakan rasio protein tinggi (74%:26%) menghasilkan performa paling baik dan optimal.

This study aimed to evaluate maggots' performance that fed with different protein-carbohydrate ratios. This study used two treatments and five replications, substrate with ratio of carbohydrate and protein 88%:12% (P1) and 74%:26% (P2), 2,25 kilogram substrates was given to the maggot during cultivation. The performance parameters measured were consumption of dry matter (DM), crude protein (CP), ether exctract (EE), crude fiber and amino acids, maggot weight, percentage of prepupae, substrate reduction, and feed conversion rasio (FCR). Data were analyzed using a T-Test of variance (Independent Sample T-Test). The performance of BSF larvae on P2 treatment were significantly higher (P<0.05) compared to the P1 treatment from consumption of DM and CP, maggot weight, percentage of prepupae, substrate reduction, and FCR. The highest consumption of the essential amino acids were lysine, isoleucine, and arginine, while the highest consumption of the non-essential amino acids were glutamic acid, aspartic acid, and alanine. In conclusion, maggot fed with high protein ratio (74%:26%) produced the best and most efficient performance.
