Abstract

This study aims to determine the feseability of bioethanol production from lignocellulosic material by using simulataneous saccharification and fermentation (SSF) processes with Aspergillus niger dan Saccharomyces cereviciae. Three different lignocellulosic materials namely sengon wood (Paraserianthes falcataria), gmelina wood (Gmelina arborea), pinus wood and (Pinus merkusii) were pretreated using kraft process to remove lignin content. Then, pulp was treated by using SSF processes. SSF runs were performed in 500 ml fermentors using a total slurry 200 ml. The substrate and nutrient media were autoclaved (121 oC and 20 minutes). The samples diluted to 2.5 % (w v-1) of total slurry was used as substrate. The substrate was added with 10 % (v v-1) A. niger (6.5 x 107 CFU cc-1) of total slurry and then inoculated with 10 % (v v-1) yeast S. cereviciae (1.5 x 109 CFU cc-1). The SSF experiments were run for 96 hours and the data were investigated periodically every 24 hours. The results showed that total of sugar and reducing sugar tended to decrease with time of inoculation whereas ethanol concentration increase significantly. The growth of A. niger and yeast S. cereviciae tended to incease in initial inoculation and decrease by the end of inoculation. The bioethanol concentration on sengon, gmelina, and pinus were 0.53, 0.45 and 0.31 % respectively and produced yields 3.61, 4.60 and 4.16% respectively. Key words: bioethanol, simultaneous saccharification and fermentation, Aspergillus niger, Saccharomyces cereviciae

Abstract

Probiotik adalah pakan tambahan dalam bentuk mikroba hidup yang menguntungkan, melalui perbaikan keseimbangan mikroorganisme dalam saluran pencernaan. Sedangkan Prebiotik merupakan substansi dari makanan yang tidak dicerna, dan secara selektif meningkatkan pembiakan dan aktivitas bakteri yang menguntungkan pada usus besar. Penelitian ini bertujuan untuk melihat persentase dan kualitas karkas ayam pedaging dari penambahan probiotik, prebiotik dan kombinasi keduanya sebagai pengganti antibiotik dalam ransum. Sebanyak 480 ekor ayam pedaging umur sehari strain Arbor Acres, dibagi dalam 4 perlakuan ransum dan 3 ulangan (40 ekor / ulangan). Ransum perlakuan yang digunakan terdiri atas : R1 = Ransum basal + 0.01% antibiotik (Zinc bacitracin), R2 = Ransum basal + 0.2% probiotik (Bacillus spp), R3 = Ransum basal + 0.2%  probiotik + 0.5% prebiotik dan R4 = Ransum basal + 0.5% prebiotik (daun katuk). Parameter yang diamati adalah : persentase karkas, lemak abdominal, hati dan daging, kolesterol hati, serum darah dan daging. Hasil penelitian menunjukkan bahwa ayam pedaging yang memperoleh probiotik dan prebiotik baik secara terpisah maupun kombinasi berpengaruh nyata (P<0,05) terhadap kualitas karkas. Kadar lemak hati, lemak paha dan kolesterol dada, secara nyata (P<0,05) lebih rendah pada perlakuan R3 dibanding dengan perlakuan kontrol (R1). Dari hasil penelitian ini dapat disimpulkan bahwa penambahan kombinasi probiotik dengan prebiotik mampu menurunkan kadar lemak dan kolesterol karkas ayam pedaging.Kata kunci : Probiotik, prebiotik, karkas, ayam pedaging

Abstract

Probiotics is a feed additive in the form of life microorganisms that balance microorganism population in the digestive tract. While prebiotics is a feed substance which is not digested, and selectively improves growth and activity of useful microbes in large intestine. The objectives of this research were to study the carcass percentage and carcass quality of broilers given a ration containing probiotics and prebiotics. Four hundred eighty day-old chicks of broiler Arbor Acres strain were divided into four dietary treatments and three replications (40 birds / replicate). Ration used was consisted of: R1 = basal ration + 0.01% antibiotics (Zinc bacitracin), R2 = basal ration + 0.2% probiotics (Bacillus spp), R3 = basal ration + 0.2% probiotics + 0.5% prebiotics and R4 = basal ration + 0.5% prebiotics (katuk leaves). The variables observed were: carcass percentage, fat content in the abdomen, liver and carcass, cholesterol content in the liver, carcass and blood serum. The results showed that the carcass quality of broiler received probiotics and prebiotics either independently or the combination was significantly (P<0.05) different. The fat content of liver and thigh, and breast cholesterol of R3 was significantly (P<0.05) lower than that of the control (R1). It is concluded that combination of probiotics and prebiotics were able to decrease the carcass fat and cholesterol content at six week of age. Key Words: Probiotics, Prebiotics, Carcass, Broilers

Abstract

Plantation waste has gained increasing attention as an alternative raw material for use in the manufacture of composite boards, i.e. waste of sago plantation. Medium density composite boards were made from zephyr of sago midrib to evaluate the effects of resin and adhesive content levels. The boards were fabricated using polyurethane (PU) and phenol formaldehyde (PF) resin with three levels of adhesive content i.e. 10%, 12%, and 14%. Physical (moisture content, density, water absorption, and thickness swelling) and mechanical (Modulus of Rupture, Modulus of Elastisity, Screw Holding, and Internal Bonding) properties of composite board were evaluated according to JIS A 5908-2003 standard. Research result showed that properties of composite board made from sago frond with 14% content level of polyurethane adhesive better than other composite board. Based on composite board properties, the board was suitable as building raw material and furniture i.e. partition, cupboard, table, and roof.
