AbstractThis study uses the draft Separated Compartments (RPT) with two factors studied were: tillage system (T) as the main plot consists of 3 levels, namely: T0 = no-tillage (control) T1 = T2 = minimum tillage tillage perfect fertilizer phosphate (P) as a subplot consisting of 4 levels, namely: P0 = 0 g / plot (control) P1 = 20 g / plot P2 = 40 g / plot P3 = 60 g / plot. From the results of the research analyzed statistics indicate that tillage systems and phosphate gives a significantly different effect, while the interaction between the two treatments showed no significantly different effect. The results of the statistical analysis that both tillage treatments and phosphate fertilizer showed no significantly different effect on the number of primary branches plant soybeans, as well as the interaction of these two treatments also showed that the effect was not significantly different. Based on the results of the statistical analysis of the data began flowering plant life observation that treatment of soybean tillage systems and fertilizer phosphate showed no significantly different effect. Interaction of tillage system and fertilizer phosphates also showed that the effect was not significantly different. Based on the results of the statistical analysis of the widespread observation that treatment of soybean leaves tillage system and fertilizer phosphate showed no significantly different effect. Further interaction between tillage systems and fertilizer phosphate showed no significantly different effect. From the results of the statistical analysis of number of pods per plant soybeans showed that tillage system treatment effect is not significantly different, but the phosphate fertilizer gives a significantly different effect on the number of pods per plant contain soy. Interaction of the two treatments showed no significantly different effect. From the results of the statistical analysis, both treamnet tillage system and fertilizer phosphate showed no significantly different effect, eventhought the interaction between tillage system and fertilizer phosphate to the observation variables dry weight per plant soy beansKeyword: influence of tillage systems, phosphate fertilizer, Glycine max L.

AbstractThe research conducted using the case study method (Case Study). Results of hypothesis testing using multiple linear regression R-square of 0.82 which indicates that it simultaneously (synchronously) no significant effect between capital and labor to the income level of farmers' maize affect the rest of 82% is influenced by other variables outside of variables studied. From the test results were statistically obtained multiple R value of 0.90% means that overall there is a close relationship between capital and labor to the income level of farmers' maize is supported by the F-calculated value is greater than the F-table at the level of 95 % (0.05 α). Partially no effect on the level of capital income of corn farmers with value t count> t-table of the 95% confidence level.While labor has no effect on the level of income of corn farmers. Implementation of the program was to improve the welfare of the community, especially at the level of farmers' income has gone well according to the needs of farmers in the village. Test results with an average difference test found that the level of income disparity between village farmers who participate in food security programs and income of farmers who do not follow the food security program of the Village 17.23 t count> t-table of 2.04 at level 95 %

AbstractThe research of grafting methyl methacrylate (MMA) onto Cyclic Natural Rubber (CNR) has been carried out. Benzoyl Peroxide (BPO) 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 and 1730 cm-1 (carbonyl group absorption) typical for carbonyl (C = O) of metal methacrylate. The degree of grafting increased with the increasing time grafting.Keywords: grafting, cyclic natural rubber, mathylmetacrilate, benzoyl peroxide

This study aims to determine the growth response of some kind of clone of cocoa ( Theobroma cacao L. ) with an organic fertilizer in a polybag with using randomized block design (RBD ) factorial with 2 factors studied , namely : The first factor is Organic Fertilizer ( O ) divided into 3 levels ie O0 = Without Giving , O1 = Amazing Bio Fertilizer Growth ( ABG ) and O2 = Fertilizer Super Bionic , and the second factor varieties Cocoa ( K ) is divided into three types namely TSH K1 = 858 , K2 = 70 and K3 = RCC PA 300 . While the parameters measured were plant height ( cm ) , number of leaves ( blade ) , stem diameter ( mm ) , leaf area ( cm ) , root fresh weight ( g ) , stem fresh weight ( g ) , root dry weight ( g ) , stem dry weight ( g ) and root volume ( cc ) . The results showed that the use of organic fertilizers provide a significant effect on the parameters of plant height , leaf number , stem diameter , leaf area , stem fresh weight , and root volume and provide no real influence on the parameters of the wet weight of the rod . Treatment varieties only significant effect on plant height parameters , and no real influence on the other parameters .While the interaction of treatment showed a marked influence on the parameters for a high cocoa seedlings and other parameters showed no real difference.Key wordas : organic fertilizer, growth, cocoa

The 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 marker

This study aimed to determine the effect of the concentration of sugar and agar concentration on the quality of banana lunkhead. This research used Completely Randomized Design (CRD) factorial with (2) two replications. The first factor is the concentration of sugar with a password (G) which consists of four levels, namely: G1 = 20%, G2 = 30%, G3 and G4 = 40% = 50%. Second factor is the concentration of gelatin with a password (A) which consists of 4 levels are: A1 = 3.0%, A2 = 3.5%, 4.0% and A3 = A4 = 4.5%. The parameters observed were: TSS, moisture content, texture, color, flavor and aroma. Statistical Result analysis on each parameter gives the following conclusion: sugar concentrations highly significant effect (p> 0.01) in the TSS. Agar concentrations highly significant effect (p> 0.01) in the TSS. Sugar concentrations highly significant effect (p> 0.01) in the moisture content. Agar concentrations highly significant effect (p> 0.01) in the moisture content. Effect of different concentrations of glucose did not significantly (p <0.05) to the texture. Agar concentrations highly significant effect (p> 0.01) in the texture. Sugar concentrations highly significant effect (p> 0.01) on the color. Sugar concentrations highly significant effect (p> 0.01) in the flavor and aroma. 3,550 highest flavor and aroma obtained at treatment G4, G1 lowest at 2,425. Agar concentrations highly significant effect (p> 0.01) for flavor and aroma. Flavor and aroma highest obtained at treatment A4 3.363, 2.613 lowest on the A1. Keyword: concentration of sugar, agar concentration, quality of banana
