KEKERABATAN GENETIK 15 AKSESI PLASMA NUTFAH KARET HASIL EKSPEDISI 1981 BERDASARKAN PENANDA MOLEKULER
Get PDFThe high genetic variability is important to produced the new improved rubber clones . To get superior progenies can be obtained by crossing between long genetic distance parental. At the present, rubber clones comes from the genetic materials of Wickham expedition in 1876. To increase the genetic diversity of the rubber, has been carried out expeditions to Brazil through organization of IRRDB ( International Rubber Research and Development Board ) in 1981 . A total of 15 selected accessions of IRRDB materials will be used in breeding programs to assemble the more productive superior clones in the future . Genetic information can be found by using molecular markers by RAPD technique. The purpose of study to determine the genetic distance of 15 germplasm accessions of the expedition IRRDB 1981 and two clones ( PB 260 and BPM 24 ) as compared of Wickham materials. The results showed there is a 75 % genetic similarity ( 25 % genetic distance ) which have two main groups , namely 10 accessions IRRDB materials divided into four subgroups and 5 accessions of IRRDB with 2 accessions of Wickham in other groups. On genetic similarity coefficient ? 95 % , accession PN 5579 has the closest relationship to the materials Wickham ( clone PB 260 and BPM 24 ) , while in IRRDB group are between the accession PN 5808 with PN 807 , PN 803 with PN 1582, PN 5814 with PN 5819 and PN 5788 with PN 5575 .Keywords: rubber, genetic relationship, germplasm, moleculer marke
PEMBUATAN SHORTENING DARI CAMPURAN RBD STEARIN DENGAN MINYAK INTI SAWIT SECARA GLISEROLISIS MENGGUNAKAN KATALIS ENZIM LIPASE DARI DEDAK PADI
Get PDFAbstractGlycerolysis reaction involves intramoleculer and intermolecular exchange of acyl groups among triglicerides resulting in the changes on the physical and chemical properties of the result triglicerides. Preparation shortening of the mixture of stearin RBD and palm kernel oil by glycerolysis using lipase enzyme as catalyzed from rice bran, in order to obtain the products that that meets the quality standards of shortening the measurement of melting point analysis was performed. The shortening produced from the mixture of the stearin RBD and palm kernel oil by glycerolysis in the mol ratio of 1:1:4, 2:2:4, 3:3:4 and 4:4:4 the melting poit was 37.2, 38.5, 40.2 and 41.50C respectively, the solid fat content at 400C was 1.80, 2.50, 5.38 and 6.15% respectively. The study indicated that rice bran as source of lipase enzyme can be use as a catalyst by glycerolysis reaction in shortening preparation.Keywords: shortening, rbd stearin, palm kernel oil, glyserolisys, lipase
THE POTENTIAL BENEFITS OF EIGHT GENOTYPE MATERIAL AMAZON 1981 PLANT RUBBER (Hevea brasiliensis Muell.-Arg.)
Get PDFThis research was conducted at the Research Center Plantation Sungei Putih from May to August 2014. The purpose of this study was to determine the potential benefits of Amazon 1981 eight genotypes material rubber tree (Hevea brasiliensis Muell.-Arg). This study uses a nested plot design (RPT). Genotypes germplasm used is PN 4578, PN 4676, PN 5819, PN 5778, PN 4543, PN 4648, PN 4808, PN 3718 and PB 260 as clones comparison. From the results of the evaluation of the origin of the Amazon eight genotypes selected in 1981 at the age of 12 years showed that genotype PN 4578 and PN 5778 has the best performance compared to PB 260 clones comparison with the range of results of dry rubber g / p / s (31.25 to 32.83 g), girth (59.78 to 65.86 cm), thick skin (8 mm) and the number of latex vessel rings (33.33 to 35.17). Genotype PN 4676 resulted in a very high wood with a potential total timber volume reached 1.53 m3/tree. Genotype PN 4578 and PN 5778 is a rubber cultivars that have the potential advantage of latex production, while the PN 4676 is the best genotype as a producer of wood. The genotypes that can be developed, especially in the breeding program to assemble rubber clones and more productive as a producer of latex and timber.Keywords: potential, genotype material Amazon, rubbe

Get PDFThe aim of this study was to evaluate response growth and production of sweet corn(Zea mays saccharataSturt) on the provision of tempe waste liquid organic fertilizer and liquid biological fertilizer. This study used a randomized factorial design with two factors, namely Liquid Organic Fertilizer Waste Tempe (T0 = control,T1 = 1 ltr/2 ltr of water/plot, T2 = 2 ltr/2 ltr of water/plot andT3 = 3 ltr/2 ltr of water/plot) and Liquid Biological Fertilizer (A0 = Control,A1 = 5 ml/3 ltr of water/plot,A2 = 10 ml/3 ltr of water/plot,A3 = 15 ml/3 ltr of water/plot) treatment repeated three times. Data were analyzed by using analysis of variance followed by different test Mean according to Duncan (DMRT) at 5% level. The results showed that provision of Liquid Organic Fertilizer Waste Tempe significantly affected plant height parameters between 2 and 4 weeks after planting (WAP), number of leaves (6 WAP)and diameter of the cob after harvesting. Provision of Liquid Biological Fertilizer significantly effected on plant height (4 WAP), stem diameter (6 WAP), leaf area (48 days after planting), cob weight, 100seed weight and diameter of the cob. The interaction between the factors giving of Liquid Organic FertilizerTempe waste and liquid bio fertilizer significantly effected on plant height (4 WAP) and the diameter of the cob after harvesting.Key words: liquid organic fertilizer, liquid biological fertilizer, growth and crop production
