Abstract

Kencur rhizome (Kaempferia galanga L.) is an aromatic herbal plant as antibacterial and anti-inflammatory. This study aims to determine the physical quality and effectiveness of gel preparations of ethanol extract and essential oil of kencur rhizome based on carbopol inhibiting Propionibacterium acnes bacteria. This study used a Randomized Block Design (RAL) with 2 different treatments of 5 levels each, namely ethanol extract gel treatment and essential oil extract gel with concentrations of 10%, 20%, 30%, 40% and 50%. The results of the gel formulation of extracts and essential oils based on carbopol showed pH, texture, spreadability and adhesiveness according to the quality standards of topical preparations. The antibacterial inhibition of the gel was moderate at 50% extract concentration (11.41 mm); and 50% essential oil (9.04 mm). Positive control treatment inhibited growth by 15.84 mm while negative control showed no response. The extract gel and essential oil of galangal rhizome had a significant effect but were less effective in inhibiting P. acnes bacteria. Adding the maximum concentration of extract and essential oil can optimize acne healing.

Abstract

The Bun-bun River was located in a mangrove forest area in Kubu Raya Regency and empties into the sea. As the main producers at the trophic level of waters, phytoplankton has an important role in assessing river quality. This study aims to find out phytoplankton community structure including abundance, diversity, uniformity, and dominance indexs in relation to Bun-bun River quality. The observations were made in the dry and rainy seasons at three stations starting from the initial end of the mangrove forest (Station 1), the middle (Station 2), and the final end which also empties into the sea (Station 3). Sampling was carried out at three points (left edge, center, right edge). Measurements of physico-chemical factors include brightness, current velocity, temperature, pH, DO, dissolved CO2, salinity, nitrate and phosphate. Phytoplankton sampling used a 30 µm plankton net mesh size and identification down to the species level. The calculated index values include abundance, diversity, uniformity, and dominance. The Bun-bun River was characterized by brackish waters with calm surface currents (<0.1 m.s-1) and a salinity between 5.4-9.48 ppt. Dissolved CO2 levels are relatively high, namely 22-30.8 mg.L-1 in the dry season and 35.2 mg.L-1 in the rainy season. During the dry season, the pH of the water becomes slightly acidic (6.51-6.76) and relatively neutral during the rainy season (7.08-7.52). Nitrate and phosphate levels were low in both seasons and all three stations. The brightness of the water was higher in the dry season than in the rainy season (20-44 cm). A total of 52 types of phytoplankton were found belonging to four classes, namely Class Bacillariophyceae (25 species), Dinophyceae (14), Chlorophyceae (12), and Chrysophyceae (1). Phytoplankton abundance index was low to moderate. The diversity index was moderate at almost all stations except for the low at Station 3 in the rainy season. The uniformity index at Station 3 was low in the dry season but high in the rainy season, and moderate in other locations. The dominance index was high at Station 3 during the dry season and moderate at other locations. Physico-chemical factors such as salinity, dissolved CO2, nitrate and phosphate levels are most likely to influence abundance, while diversity was influenced by dominance.

Abstract

The bacteria Staphylococcus aureus, a normal component of human flora, is easily mutated and antibiotic-resistant, leading to the creation of Methicillin-Resistant Staphylococcus aureus (MRSA). This bacterium is a difficult-to-control nosocomial infection in healthcare settings, so it must be stored using specialized preservation agents, like DMSO, to investigate the nature and characteristics of these bacteria for prevention, control, and therapy. The purpose of this study was to evaluate the survival of MRSA bacteria that had been kept in a DMSO solution at various temperatures and periods. This study was carried out between July and October2022 using a one-shot study case research design, data analysis, and quantitative descriptive analysis. According to the findings, MRSA bacteria held in 15% DMSO solution lost viability over time and at various storage temperatures. Among various bacterial species held at various storage temperatures, MRSA bacteria had the lowest colony loss rate (-20 °C). Based on the findings of this study, it can be said that the preservation of MRSA bacteria at freezing temperature (-20 °C) and storage length of one month resulted in the greatest survivability of the bacteria when stored in 15% DMSO solution.
