Abstract

The content of betel leaf (Piper betle) includes essential oils, alkaloids, flavonoids, phenols, and steroids. Flavonoid compounds in P. betle show a mechanism of action in damaging bacterial cell proteins and disrupting irreparable membranes. On the other hand, mint leaves (Mentha piperita) contain essential oil ranging from 1-2%, with menthol content around 80-90%, as well as mentone, d-piperitone, hexanol phenyl acetate, ethyl amyl carbinol, and neomenthol. The aim of this study is to determine the effectiveness of the combination of P. betle extract and M. piperita extract in inhibiting the growth of Streptococcus mutans (S. mutans) bacteria using the well diffusion method. Extraction of P. betle and M. piperita extracts were performed using the maceration method. The extraction results showed a yield of 24.94% for the P. betle extract and 35.39% for the M. piperita extract. The antibacterial testing against S. mutans showed an inhibition zone of 21.83 ± 1.58 mm for the single P. betle extract (ML), 11.2 ± 1.00 mm for the M. piperita (GBL), and 11.76 ± 0.57 mm for the combination extract (GBL/ML). There is an influence of the combination of P. betle and M. piperita extracts on the antibacterial effectiveness against S. mutans, although the inhibition zone of the P. betle is larger, measuring 21.83 ± 1.58 mm.

Abstract

Macrozoobenthos are basic aquatic organisms that live above or life on the bottom of the waters. This study aims to determine the diversity, uniformity and dominance of macrozoobenthos. This research was carried out in the Kenten River, Banyuasin Regency in January-April 2022 which consisted of three sampling points and this study was taken every 2 weeks for 2 months. Sampling, samples of macrozoobenthos were taken using the Ekman grab tool, then the samples that had been taken were separated from the mud and other objects with 0.5– 1 mm, levels and offered 70% alcohol. The results of the study found that there were 3 divisions, namely the Oligochaeta, Malacostraca and Insecta divisions. Based on research conducted to enjoy the highest experience at station II with a value of 184 ind/m2 and the lowest at station III with a value of 52 ind/m2. The Diversity Index (H') ranges from 0.10-0.22. The uniformity index (E) ranges from 0.15-0.23. The dominance index (D) ranges from 0.90 to 0.95
