Penelitian bertujuan mengkaji pengaruh dan taraf terbaik suplementasi hidrolisat maggot BSF sebagai sumber pakan fungsional terhadap konsumsi lemak kasar dan gross energy pakan Ayam Sentul. Proses hidrolisis fermentasi dengan Lactobacillus casei yang berfungsi untuk memecah senyawa kompleks menjadi bentuk yang lebih sederhana yang dapat meningkatkan asam lemak PUFA. Materi yang digunakan adalah 100 ekor Day Old Chick (DOC) Ayam Sentul. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) 4 perlakuan dan 5 ulangan. Perlakuan yang diberikan yaitu P0=pakan basal, P1= P0 + 2% Hidrolisat Maggot BSF, P2 = P0 + 4% Hidrolisat Maggot BSF, dan P3 = P0 + 6% Hidrolisat Maggot BSF.  Variabel yang diukur adalah konsumsi lemak kasar dan konsumsi gross energy pakan Ayam Sentul. Analisis data penelitian di uji menggunakan Analysis Of Variance (ANOVA) dengan uji lebih lanjut menggunakan Beda Nyata Jujur (BNJ) serta Orhogonal Polynomial. Hasil untuk kedua parameter menunjukkan bahwa suplementasi hidrolisat maggot BSF yang dihidrolisis menggunakan Lactobacillus casei memberikan pengaruh sangat nyata (P<0,01) terhadap konsumsi lemak kasar dan konsumsi gross energy pakan Ayam Sentul dibandingkan pakan basal. Hasil rataan nilai konsumsi lemak kasar pakan Ayam Sentul pada perlakuan P0,P1,P2, dan P3 yaitu 2,56±0,15, 2,89±0,14, 3,27±0,10 dan 3,83±0,11, sedangkan rataan nilai konsumsi gross energy pakan pada perlakuan P0,P1, P2, dan P3 yaitu 123,12±7,43, 126,91±6,23, 142,51±4,20 dan 155,40±4,35. Hasil Uji lanjut Orthogonal Polynomial pada konsumsi lemak kasar dan gross energy berpola linier dengan persamaan regresi konsumsi lemak kasar Y = 2,5108 + 0,2084x dan konsumsi gross energy Y = + 120,12 + 5,6213x. Suplementasi hidrolisat maggot BSF hasil hidrolisis menggunakan Lactobacillus casei dapat meningkatkan konsumsi lemak kasar dan gross energy pakan Ayam Sentul sampai dengan taraf 6% dan masih terus meningkat dan belum menimbulkan efek penurunan konsumsi.

This reaserch aims to examine the effect and optimal level of Black Soldier Fly (BSF) maggot hydrolysate supplementation as a functional feed ingredient on crude fat and gross energy intake in Sentul chickens. The fermentative hydrolysis process using Lactobacillus casei breaks down complex compounds into simpler forms that can increase polyunsaturated fatty acids (PUFAs). The subjects used were 100 Day-Old Chicks (DOC) of the Sentul chicken breed. The study employed a Completely Randomized Design (CRD) with 4 treatments and 5 replicates. The treatments were as follows: P0 = basal diet, P1 = P0+ 2% BSF Maggot Hydrolysate, P2 = P0 + 4% BSF Maggot Hydrolysate, and P3 = P0 +6% BSF Maggot Hydrolysate.  The variables measured were crude fat intake and gross energy intake of Sentul chickens. The research data were analyzed using Analysis of Variance (ANOVA), with further tests using the Honest Significant Differences (HSD) test and orthogonal polynomials. The results for both parameters showed that supplementation with BSF maggot hydrolysate hydrolyzed using Lactobacillus casei had a highly significant effect (P < 0.01) on crude fat intake and gross energy intake in Sentul chickens compared to the basal diet. The mean crude fat intake values for Sentul chickens in treatments P0, P1, P2, and P3 were 2.56 ± 0.15, 2.89 ± 0.14, 3.27 ± 0.10, and 3.83 ± 0.11, while the mean values for gross energy intake in treatments P0, P1, P2, and P3 were 123.12 ± 7.43, 126.91 ± 6.23, 142.51 ± 4.20, and 155.40 ± 4.35, respectively. The results of the Orthogonal Polynomial analysis on crude fat and gross energy intake showed a linear pattern with the following regression equations: crude fat intake Y = 2.5108 + 0.2084x and gross energy intake Y = 120.12 + 5.6213x. Supplementation with BSF maggot hydrolysate produced using Lactobacillus casei can increase crude fat and gross energy intake in Sentul chickens up to a level of 6%, and intake continues to increase without causing a decrease in consumption
