Abstract

Suatu penelitian telah dilakukan untuk melihat sejauh mana pengayaan nilai nutritif sekam padi berbasis bioteknologi “Effective Microorganisms” (EM4). Penelitian ini telah dilaksanakan di Laboratorium Teknologi Pengolahan dan Industri Makanan Ternak Fakultas Peternakan UNSRAT, kemudian dilanjutkan dengan analisis sampel di Laboratorium BARISTAND (Badan Riset dan Standarisasi Industri) Sulut. Lamanya penelitian dari bulan September sampai November 2011. Penelitian ini menggunakan metode eksperimen dengan pola Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan dan 5 ulangan, dengan perlakuan sebagai berikut, yaitu ; R0: Sekam Padi non Rekayasa  (SPnR), R1 : Sekam Padi Rekayasa EM + 2500 ml air (SPRns), R2 : Sekam Padi Rekayasa EM + 2500 ml cuka saguer (SPRps). Variabel yang diukur yaitu nilai nutritif sekam padi  meliputi protein, serat kasar, dan energi sekam padi non rekayasa dan rekayasa dengan EM4. Hasil yang diperoleh dari penelitian ini menunjukan bahwa sekam padi yang direkayasa dengan EM4 mengalami peningkatan kadar protein dari 1,92% menjadi 2,67% atau terjadi kenaikan sebesar 39%, sedangkan rekayasa EM4 + cuka saguer kadar proteinnya menjadi 2,22% (terjadi kenaikan 15%). Untuk serat kasar terjadi penurunan dari 37,33% menjadi 13,02%, sedangkan rekayasa dengan EM4 + cuka  saguer menjadi 13,24%. Kemudian untuk kadar energi terlihat bahwa sekam padi yang direkayasa dengan EM4 menghasilkan peningkatan kadar energi dari 302,33 KKal/Kg menjadi 375,62 KKal/Kg atau terjadi kenaikan sebesar 24%, sedangkan untuk sekam padi rekayasa EM4 + cuka saguer kadar proteinnya menjadi 373.08 KKal/Kg. Hasil analisis keragaman menunjukan bahwa sekam padi yang difermentasi dengan EM4 memberikan pengaruh berbeda sangat nyata (P < 0,01). Dari penelitian yang telah dilakukan diambil kesimpulan bahwa bahwa rekayasa sekam padi dengan “EM4” terjadi pengayaan nilai nutritif sekam padi yang ditandai dengan turunnya kadar serat kasar dan meningkatnya kadar protein dan energi.

Abstract

ABSTRACTThe use of antibiotics in chicken feed is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the physical and chemical quality of Lohmann chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were no differences between treatments on the performance of laying hens (egg production, egg weight, egg mass, feed conversion); physical quality (eggshell, egg yolk, egg white, shell thickness, egg yolk, Haugh unit, egg index) and chemistry (superoxide dismutase production, thiobarbituric acid reactive substances (TBARS) and Lohmann chicken egg cholesterol) but there was a difference in feed intake. The uronic acid extracted from S. crassifolium has not been able to increase the production and quality of Lohmann chicken eggs.Keywords: lohmann chicken, quality of eggs, Sargassum crassifolium, uronic acid

Abstract

The objectives of this study were to characterize the chemical properties and determine the antibacterial activity of S. crassifolium against Salmonella sp. The algae was extracted using water and ethanol. The results showed that the yield of E. spinosum extract using water solvent showed the highest value (6.53%), followed by S. polycystum extract (3.27%) and S. crassifolium (2.34%). The highest concentration of uronic acid was shown in S. crasifolium extraction (0.90%) using water solvent and the lowest in E. spinosum (0.04%) using ethanol solvent. Inhibitory test against Salmonella sp using 10% S. crassifolium extract showed higher value than using 2.5; 5.0 and 7.5% S. crassifolium extract. It is concluded that the extract of S. crasifolium contain 0.90 % uronic acid with pH= 8 of that capable of inhibiting the growth of Salmonella sp.
