Abstract

The aim of this studi is to examine the antibacterial activity of aloe vera leaf infuse (Aloe barbadensis Miller) against human pathogens such as Pseudomonas aeroginosa, Salmonella typhi, Staphylococcus aureus, dan Streptococcus pneumonia. Antibacterial activity test of 20, 40, and 60% aloe vera leaf infuse was using agar well diffusion method. The antibacterial activity is indicated by the formation of a clear zone around the wells. All the concentration of aloe vera leaf infuse (Aloe barbadensis Miller) showed signifi cant antibacterial activity against Pseudomonas aeroginosa, Salmonella typhi, Staphylococcus aureus, but did not show antibacterial activity against Streptococcus pneumonia. Aloe vera leaves infuse at a concentration of 60% can inhibit the growth of Pseudomonas aeroginosa indicated by the formation of a clear zone (16.5 mm), the bacteria Salmonella typhi (34 mm), and Staphylococcus aureus (15 mm). The research recommended aloe vera leaf would be suitable for use as antibacterial agent of disease caused by Pseudomonas aeroginosa, Salmonella typhi, and Staphylococcus aureus.

Abstract

 AbstractThe problems of this research were the lack of motivation and the low achievement of students in SMA Negeri 1 Sungai Raya. Purposes of this research were to determine: 1) whether there was a significant difference of achievement beetwen students who were taught using CIRC Cooperative Integrated Reading and Composition model and conventional method on koloid materials, 2) effect size of applying CIRC Cooperative Integrated Reading and Composition  model toward achievement on koloid materials, 3) whether there was a significant difference of motivation beetwen students who were taught using CIRC Cooperative Integrated Reading and Composition model and conventional method on koloid materials. Quasi-experimental with nonequivalent control group design was used as research method. The sample were students XI IPA 3  as control class and XI IPA 1 as experimental class that were determined with random sampling technique. Motivations and achievement were analyzed using U-Mann Whitney. The result of data analysis showed that there were  significant difference motivations and learning achievement beetwen students who were taught using CIRC Cooperatif Integrated Reading and Composition model and conventional method. CIRC Cooperative Integrated Reading and Composition model gave effect of 43.0%  influence on student achievement. Keyword: Cooperative Integrated Reading and Composition, motivations, achievement, koloid materials.

Abstract

Staphylococcus aureus is one of the acne-causing bacterias. Chemical compound in the Bay leaves are well-known as an antibacterial agent to inhibit the growth of Staphylococcus aureus. This study aimed to determine the influence of various Bay leaf (Eugenia polyantha Wight) infusing concentration toward the inhibition of Staphylococcus aureus growth. This research is experimental study with post-test and control group design. The sensitivity test methods toward Staphylococcus aureus were divided into five groups of bay leaf infusing concentration of 60%, 70%, 80%, 90%, and 100%. This method are used in 6 times to obtained 30 datas. Then, the datas were analyzed descriptively and analytically by ANOVA using SPSS 16.0 for Windows. The infusion of Bay leaves had inhibition activity against Staphylococcus aureus growth based on ANOVA test which showed a significance value 0.000 <0.05. There was a proof that the infusion of Bay leave have an effect to inhibit the growth of Staphylococcus aureus.
