Abstract

Penelitian ini bertujuan untuk mengevaluasi pengaruh berbagai macam limbah organik sebagai media pertumbuhan maggot terhadap profil asam lemak dan komposisi serat kasarnya, serta pengaruh penggunaan tepung maggot sebagai aditif pakan terhadap penampilan produksi ayam pedaging. Penelitian ini terdiri dari dua tahap yaitu penelitian tahap 1 dan penelitian tahap 2. Penelitian tahap 1 merupakan proses pemeliharaan maggot dengan media yang berbeda yaitu M0 = sampah buah; M1 = sisa makanan; M2 = ampas tahu; M3 = 50% sampah buah + 50% ampas tahu; dan M4 = 50% sampah buah + 50% sisa makanan. Maggot yang telah dipelihara akan dipanen pada hari ke-28, kemudian dilanjutkan pada tahap pengujian laboratorium yaitu profil asam lemak meggunakan metode kromatografi gas dan komposisi serat kasar menggunakan metode van soest. Hasil penelitian menunjukkan komposisi asam lemak pada maggot didominasi oleh SFA yaitu asam laurat (34,28 – 38,39%), asam palmitat (17,45 –19,25%), asam arakidat (8,8 – 10,41%), dan asam miristat (7,35 – 9,36%). USFA; asam linolelaidate (13.51 – 16.86%), asam oleat (1.64 – 1.91%), asam nervonate (1.34- 1.46%), dan asam linolenat (0.65 – 1.03%). Komponen serat yang diukur adalah NDF (20,19 – 29,11%), ADF (10,43 – 17,55%), hemiselulosa (8,86 – 11,56%), selulosa (2,51 –10,49%), dan lignin (0,14 – 0,75%). Ditinjau dari tingginya asam laurat dan asam lemak esensial, serat kasarnya M3 merupakan perlakuan terbaik sehingga dipilih untuk digunakan sebagai pakan aditif bagi ayam pedaging. Penelitian tahap 2 merupakan penelitian lapang. Materi yang digunakan yaitu DOC ayam pedaging strain Lohmann yang dipelihara selama 35 hari. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 ulangan yang terdiri dari 8 ekor di setiap unit percobaan. Kelompok perlakuan terdiri dari P0 = pakan basal; P1 = pakan basal + tepung maggot 0,25%; P2 = pakan basal + tepung maggot 0,50%; P3 = pakan basal + tepung maggot 0,75%; dan P4 = pakan basal + tepung maggot 1%. Analisis data menggunakan analysis of variance (ANOVA). Apabila terdapat perbedaan nyata dilanjutkan uji jarak berganda Duncan (DMRT). Hasil penelitian menunjukkan bahwa tepung maggot sebagai aditif pakan memberikan pengaruh sangat nyata (P<0,01) terhadap BB akhir dan FCR. perlakuan juga memberikan pengaruh nyata (P<0.05) terhadap nilai IP, serta tidak berpengaruh nyata (P>0,05) terhadap konsumsi pakan, dan IOFC. Kesimpulan dari penelitian ini yaitu pemberian tepung maggot 1% sebagai aditif pakan menunjukkan hasil terbaik berdasarkan penampilan produksinya.

English Abstract

This study aimed to evaluate the effect of various type of organic wastes implemented as growth media for maggot on their fatty acid profile and crude fiber composition, as well as the effect of implementation of powdered maggot as feed additive on performance production of broiler. The conduction of the study was divided into two stage, namely stage 1 and stage 2. stage 1 was composed of the rearing process for maggot in different media including M0 = fruit waste; M1 = food waste; M2 = tofu byproduct; M3 = 50% fruit waste + 50% tofu byproduct; and M4 = 50% fruit waste + 50% food waste. Maggot that had been reared was harvested at age 28 day, then processed in laboratorium to be tested for its fatty acid profile by chromatography gas and crude fiber composition by van soest methode. Result of study showed composition of fatty acid in maggot was dominated by SFA, which was lauric acid (34.28-38.39%), palmitic acid (17.45-19.25), arachidic acid (8.8 – 10.41%), and myristic acid (7.35 – 9.36%). USFA; linolelaidic (13.51 – 16.86%), oleic acid (1.64 – 1.91%), nervonic acid (1.34 – 1.46%), and linolenic (0.65 – 1.03%). Fiber component measured were NDF (20.19 – 29.11%), ADF (10.43 – 17.55%), hemicellulose (8.86 – 11.56%), cellulose (2.51 – 10.49%), and lignin (0.14 – 0.75%). In terms of fatty acid profile and crude fiber, M3 was considered to be the best treatment and chosen to be applied as feed additive for broiler. Stage 2 was a field study. The materials used were Lohmann broiler DOC which were reared for 35 days. The study implemented Completely Randomized Design (CRD) with 5 treatments and 4 replications that were consisted of 8 birds for each unit. The collection of treatments were composed of T0 = basal feed; T1 = basal + powedered maggot 0.25%; T2 = basal + powdered maggot 0.50%; T3 = basal + powdered maggot 0.75%; and T4 = basal + powdered maggot 1%. Analysis of Variance (ANOVA) was implemented. Should there have been significance in difference, Duncan’s Multiple Range Test (DMRT) would be conducted. The result showed powder maggot meal to be highly significant feed additive (P<0.01) on Final BW and FCR. Treatments also exerted significant effect (P<0.05) on IP, and non-significant (P>0.05) on feed intake, and IOFC. In conclusion, powder maggot meal provided at 1% of feed as feed additive exhibited the best result according to performance production.
