Abstract

 ABSTRACT Comparative studies on  nutrient uptake ability of rice plants (Oryza Sativa.L) that represent groups of plants dicotyledonous with long beans (Vigna sinensis) representative of the group of plants monocotyledonous have been conducted. The study was conducted on a community farm located in the Village of Sungai Sapih  Padang, at plants are used as the sample is sokan varieties. The root of leaves and fruit as well as beans, the same parts are used as sample.Morphological observations of roots, leaves and fruit using the SEM showed the difference between the rice and beans. While the homogenity for fruit rice and beans especially almost the same. The results of nutrient measurements performed by ICP - MS, elemental carbon is the largest percentage of nutrients in the two plants in average above 50% in all parts of the plant. The percentage of Ca, Mg and N elements in the leaves of beans is higher than in the rice leaves, otherwise the percentage of Si element is higher in the rice plants. Key words: absorption, nutrients, Oryza sativa, Vigna sinensis, ICP-MS

Abstract

Rhodomyrtone, an antibacterial constituent was isolated from the active fraction of theleaves extract of Karamuntiang, Rhodomyrtus tomentosa (Aiton) Hassk. In this presentstudy, the topical cream formula of rhodomyrtone 2% in vanishing cream was evaluated byin vitro and in vivo preclinical test. The in vitro test was peformed against Staphylococcusaureus ATTC 6538 and Staphylococcus epidermidis ATTC 12228 by using disk agardiffusion method, while the in vivo test was evaluated on the surface of skin infection area ofthe rabbit caused by Staphylococcus aureus. Both these tests were guided bychloromphenicol 2% cream as a comparison. The topical cream of rhodomyrtone 2% invanishing cream showed diameters of inhibition zones of 15 mm and 26 mm towardStaphylococcus aureus and Staphylococcus epidermidis respectively. These diffusions werelower than inhibition zones of chloromphenicol 2% cream which has 30 mm and 32 mm forthe same bacterias in the same condition. The in vivo test showed that rhodomyrtone 2%topical cream can reduced that skin infection and did not caused irritation on the testedrabbits.ABSTRAKRhodomyrtone adalah suatu konstituen antibakteri fraksi aktif ekstrak daun karamuntiang,Rhodomyrtus tomentosa (Ait) Hassk.

Abstract

In this study, researchers used respondents' data, such as gender, age and duration of work of respondents to be able to provide information about the characteristics of respondents. Where from the questionnaire distributed questionnaire as many as 50 respondents using census techniques.Data analysis with parametric and non parametric statistics using SEM-PLS (Structural Equation Modeling-Partial Least Square) regarding research variables, instrument test, normality test, hypothesis test, and discussion of the results of hypothesis testing and Path Path Analysis. This study uses path analysis (path analysis) to test the pattern of relationships that reveal the influence of variables or a set of variables on other variables, both direct influence and indirect influence. The results of the study are as follows: The effect of the X3 variable on X4 has a P-Values value of 0.047 <0.05, so it can be stated that the influence between X3 and X4 is significant. The effect of the X3 variable on Y has a P-Values value of 0.013> 0.05, so it can be stated that the effect between X3 on Y is significant. The effect of the X4 variable on Y has a P-Values value of 0.030> 0.05, so it can be stated that the influence between X4 on Y is significant. The effect of X1 on X4 has a P-Values value of 0.002 <0.05, so it can be stated that the influence between X1 to X4 is significant. The effect of X1 on Y has a P-Values value of 0.008> 0.05, so it can be stated that the influence between X1 and Y is significant. The effect of the X2 variable on X4 has a P-Values value of 0.035 <0.05, so it can be stated that the effect between X2 on X4 is significant. The effect of the X2 variable on Y has a P-Values value of 0.004 <0.05, so it can be stated that the effect between X2 on Y is significant.
