The research of grafting methyl methacrylate onto Cyclized Natural Rubber has been carried out. Dicumyl Peroxide was used as a inisiator and temperature condition at 90oC with variation of time 1 and 2 hours. Grafting process was done with technique of reflux in a tree-neck flask with condenser and oil bath. Spectra analysis FTIR performed for determine the presence of grafted MMA on the backbone of CNR. The results showed that the product CNR-g-MMA was formed with the marked appearance of the absorption peak wave numbers at 1731 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of methyl methacrylate. The degree of grafting increased with the increasing time grafting.Keywords: grafting, cyclic natural rubber, mathylmetacrilate, dicumyl peroxide

The purpose of this study to determine the test several varieties of peanut (Arachis hypogaea L.) against organic fertilizer fish, using a plot design Divided (RPT) which consists of two factors, namely, varieties factor (V) as the main plot that consists of 2 levels : V1 = varieties Elephant, V2 = varieties rabbits and Fish fertilizer factor (I) as a subplot which consists of 4 levels: I0 = Without fertilizer application (control), I1 = 10 tonnes / ha = 1 kg / plot, I2 = 30 ton / ha = 3 kg / plot, I3= 50 tonnes / ha = 5 kg / plot, and one each in repeat three times. The parameters observed among others: plant height (cm), number of branches (branch), number of pods per plant samples (pods), number of pods per plot (pod), seed weight per plant sample (g), seed weight per plot (g ), and the weight of 100 seeds (g). The results showed that the factors giving Variety shows Elephant better varieties of varieties Rabbits of all parameters were observed. As for the factors giving the best Organic Fertilizer Fish on giving I2 = 30 tonnes / ha = 3 kg / plot.Keywords: Variety, Fertilizers Fish, Peanut, Growth, Production
