Morphological Variation in Arabica Coffee (Coffea arabica L.) Growing in North Sumatra Indonesia Sabam Malau; and Samse Pandiangan
Indonesian Journal of Agronomy Vol. 46 No. 3 (2018): Jurnal Agronomi Indonesia
Publisher : Indonesia Society of Agronomy (PERAGI) and Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University, Bogor, Indonesia

Genetic variation is important in plant breeding. However, information on the genetic variability of Arabica coffee especially in coffee field of North Sumatra was not yet available. Magnitude of morphological variation, genotypic variation, phenotypic variation, heritability, genetic advance, genetic correlation, and phenotypic correlation of plant vigors and yield components of 28 genotypes were evaluated using nested design. This research showed morphological and genetic variations of the genotypes in the field. Based on the research locations as operational taxonomic unit, the genotypes were separated into three clusters. Most of the parameters had low to moderate genotypic variation, while phenotypic variation was moderate to high. Heritability and genetic advance were low, moderate, and high. Several plant vigors and yield components had a positive significant genetic and phenotypic correlation one another, and several had negative ones. Coffee berry borer infestation (CBBI) had a highly significant negative genetic correlation with leaf width (rG = -0.309**), leaf weight (rG = -0.671**), fruit diameter (rG = -0.320**), and bean length (rG = -0.175**). CBBI showed a significant positive genetic correlation with mesocarp pH (rG = 0.134*). To reduce CBBI, selection for higher leaf weight is better. Selection on lower pH of mesocarp could be considered to decrease CBBI.Keywords: cluster analysis, genetic correlation, genetic heritability, variability

Soyghurt is a fermented soy milk product using Streptococcus thermophilus and Lactobacillus bulgaricus bacteria. Efforts to enrich drinks high in antioxidants are carried out by combining food ingredients that can function as antioxidants such as soybeans and jicama. The combination of these two food ingredients and the assistance of the fermentation process by S. thermophilus and L. bulgaricans was expected to increase antioxidant activity in soyghurt production.This study used a completely randomized design (CRD) with 2 factors, namely: the first factor was the ratio of soybean juice and yam juice (S) which consisted of 4 treatment levels, namely: S0 = 100: 0, S1 = 75: 25, S2 = 50: 50, S3 = 25: 75, S4 0: 100. Meanwhile for the second factor was the duration of fermentation (F) which consisted of 3 levels of treatment, namely: F0 = 6 hours, F1 = 8 hours, F2 = 10 hours. The parameters observed were total solids, total acid, organoleptic value, antioxidant activity, and total lactic acid bacteria in jicama soyghurt on the best samples.The results showed that both treatment factors had a very significant effect (P <0.01) on total solids, total acid, and organoleptic tests of soyghurt. The study showed that the comparison of soybean juice and jicama juice and fermentation duration resulted a high protein content value of 9.18% and was in accordance with the SNI yoghurt protein content, namely minimum of 3.5%. Antioxidant activity of yam bean soyghurt obtained an IC 50 value of 18.110 mg / L and it was a very strong antioxidant. Total lactic acid bacteria on yam soyghurt was 108 CFU / ml and it was high.Based on this research results, it was suggested that soyghurt processing may use a combination with other types of fruits and use natural food coloring to give different flavors and increase the nutritional values of soyghurt.

Hard candy is a solid and hard-textured snack, the main ingredients in the manufacture of hard candy are sucrose, water, glucose syrup, while the additives are flavor, coloring and acidifying. The ratio of the amount of sucrose and glucose syrup used in the manufacture of hard candy will determine the texture that is formed. In general, hard candy is only known as a source of calories and does not contain antioxidants. One type of plant that is rarely used is the fruit of Senduduk Bulu (Clidemia hirta L.), this fruit contains high levels of antioxidants that can ward off free radicals in the body. The aims of this research are to investigate the effect of sucrose and glucose syrup ratio and the addition of different concentrations of senduduk bulu extract on physicochemical and organoleptic properties of hard candy. This study used a Factorial Completely Randomized Design consisting of 2 factors, namely the ratio of sucrose and glucose syrup consisting of 3 levels (70%: 30%, 75%: 25% and 80%: 20%) and the concentration of senduduk bulu extract with 4 levels. (0%, 3%, 6%, 9%). The parameters observed were water content, reducing sugar, antioxidant activity, hedonic organoleptics (color, taste, and texture). The results concluded that the ratio of sucrose and glucose syrup had a significant effect on reducing sugars concentration (P< 0.05), and was very significant (P <0.01) on organoleptic (color, taste) but did not affect water content, and organoeptic texture of hard candy . The addition of senduduk bulu extract had a very significant effect (P <0.001) on water content, reducing sugar concentration, and organoleptics (color, taste, texture) on hard candy senduduk bulu. The hard candy formula most preferred by panelists based on the hedonic test was A1B4 treatment (the composition of the ratio of sucrose and glucose syrup 70%: 30% with 9% senduduk bulu extract). The average value of the panelists' preference level for the parameters of color 3.66, taste 3.54, texture 2.82 and the average value of the test results 1.98% water content, 6.26% reduction sugar and has a very strong antioxidant activity with IC50 value of 36.84 ppm. All analysis tests met the quality requirements of SNI3547.1: 2008 hard candy.
