The aims of this study was to evaluate the response of growth and yield of green bean (Vigna radiata L.) against solid organic fertilizer and liquid organic fertilizer. The design used was a factorial randomized block design (RAK-F) with the two factors studied, namely: Factor Nafos Guano organic fertilizer dense (N) consists of 4 levels of treatment that is N0 = without giving, N1 = 16,88 g / plot (75 kg / ha), N2 = 33,75 g / plot (150 kg / ha) and N3 = 50,63 g / plot (225 kg / ha). Factors Supermes liquid organic fertilizer (S) comprises 3 levels of treatment that is S0 = without giving, S1 = 1,5 cc / liter of water and S2 = 3 cc / liter of water. The parameters measured were plant height, number of branches, days to flowering, pod weight per plant, weight of pods per plot, seed weight per plot and weight of 100 seeds. The results showed that administration of solid organic fertilizer significantly affect the parameters of plant height, weight of pods per plant and 100 seed weight. Dose of the best applications that N3 = 50,63 g / plot (225 kg / ha). Liquid organic fertilizer significantly affect the parameters of plant height, days to flowering and pod weight per plant. Dose of the best applications that S2 = 3 cc / liter of water. The interaction between organic fertilizer liquid organic fertilizer dense and not a real effect on all parameters measured. Green bean crop production due to solid organic fertilizer and liquid organic fertilizer is as much as 9427.63 g (1.16 tonnes / ha). Keywords: green beans, nafos guano and supermes

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
