Konsumsi Nutrien dan Performa Maggot Hermetia illucens yang Diberi Substrat Berprotein Tinggi dengan Kadar Air Berbeda | Nutrient Consumption and Performance of Hermetia illucens Maggots Fed with High-Protein Substrate with Different Moisture Content

Penelitian ini bertujuan mengevaluasi pengaruh substrat berprotein tinggi dengan kadar air substrat yang berbeda terhadap konsumsi nutrien dan performa maggot Hermetia illucens. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 6 ulangan. Maggot dipelihara dari umur 5 sampai 16 hari dengan perlakuan yang terdiri dari P1 (100 gram pakan + 100 gram air) dengan kadar air 56,73% , P2 (100 gram pakan + 150 gram air) dengan kadar air 63,84%, P3 (100 gram pakan + 200 gram air) dengan kadar air 70,84%, dan P4 (100 gram pakan + 250 gram air) dengan kadar air 74,64%. Hasil penelitian menunjukkan bahwa penambahan air pada substrat berpengaruh nyata (P<0,01) terhadap konsumsi nutrien, bobot maggot, persentase prepupa, reduksi susbtrat, dan biokonversi. Perlakuan P4 (100 gram pakan + 250 gram air) dengan kadar air 74,64% menunjukkan peningkatan pada seluruh parameter yang meliputi nilai konsumsi nutrien, bobot badan, persentase prepupa, reduksi substrat, dan biokonversi. Hal ini mengindikasikan bahwa substrat beprotein tinggi dengan kadar air yang optimal dapat meningkatkan konsumsi dan performa maggot.

This study aimed to evaluate the effect of high protein substrate with different moisture content on nutrient consumption and Hermetia illucens maggot perfomance. This study used a completely randomized design (CRD) with 4 treatments and 6 replications. Maggots were reared from 5 to 16 days of age with treatments consisting of P1 (100 grams of feed + 100 grams of water) with 56.73% moisture content, P2 (100 grams of feed + 150 grams of water) with 63.84% moisture content, P3 (100 grams of feed + 200 grams of water) with 70.84%, and P4 (100 grams of feed + 250 grams of water) with 74.64% moisture content. The results showed that the addition of water to the substrate had a significant effect (P<0.01) on nutrient consumption, maggot weight, prepupae percentage, susbtrate reduction, and bioconversion. The P4 treatment (100 grams of feed + 250 grams of water) showed an increase in all parameters including the value of nutrient consumption, body weight, percentage of prepupae, substrate reduction, and bioconversion. This indicates that a high-protein substrate with optimal water content can increase Hermetia illucens maggot consumption and performance.
