Abstract

Plant anatomy is one of the important basic data to reveal the potential of a plant. Anatomical data provide an overview of the internal structure of the plant body. This structure is influenced by the environment, the same thing is also likely to occur in Komak kedit plants which are widely planted on Lombok Island. Komak kedit (Phaseolus lunatus L.) is a species of legume (Fabaceae) originating from Central America. The purpose of this study was to analyze the differences or variations in the anatomical structure of the Komak kedit (P. lunatus) on Lombok Island. Data analysis in this research was descriptive qualitative and triangulation. The results showed that the anatomical structure of the roots, stems, leaves, flowers, fruits, and seeds of the Komak kedit plant on Lombok Island had similar structure, such as epidermis, cortex, and stele. However, in this study, there were more differences in the number of stomata on leaves in West Lombok compared to East Lombok, Central Lombok, North Lombok, and Mataram. This was caused by differences in the environment where the plants were planted, such as water content.

Abstract

Dental caries is an infection disease of tooth tissue caused by Streptococcus mutans bacteria. Atsiri is essential oil is a liquid-shaped compound that is thought to have potential as an antibacterial. The purpose of this study was to determine the antibacterial potential of essential oil of limau lime in controlling Streptococcus mutans bacteria. The antibacterial test in this study used disk disfussion method with 8 treatment groups and 4 replications is 5 concentrations of atsiri oils, 1 positif disc amoxicillin antibiotic, 2 negative control with DMSO and aquades. The data obtained were analyzed with normality test, Anova test and BNT test. Isolation of atsiri’s oil of limau lime in this study using the method of steam-water distillation. Streptococcus mutans bacteria were isolated from dental caries patients and tested using macroscopic, microscopic, gram staining, and biochemical methods. The study found that the atsiri oils of limau lime has antibacterial activity in vitro against Streptococcus mutans bacteria, as evidenced by the formation of an inhibit zone. Concentration as 100% with 15.38mm inhibitory zone diameter is the most effective concentration to inhibit the growth of Streptococcus mutans bacteria. The statistical analysis revealed a significant influence between the treatments at the 5% significance level.
