Crude Drugs Standardization, Total Flavonoid and Phenolic Content Profile, and Antimicrobial Activity of Red Ginger and Lemongrass Combination
Get PDFBaturraden people use a combination of red ginger rhizomes and lemongrass leaves for the treatment of masuk angin. This study aims to evaluate the quality profile of red ginger and lemongrass crude drug, total flavonoid content (TPC), total phenolic content (TFC), and the antimicrobial activities of their combination water extracts. The quality of both crude drugs was standardized to Indonesian Herbal Pharmacopeia (IHP). The TPC and TFC of red ginger and lemongrass combination in five different ratios were determined by standard UV-Vis spectrophotometry methods. The antimicrobial activity was evaluated using the microdilution method against patient-isolated multidrug-resistant (MDR) Staphylococcus aureus and Candida albicans. Lemongrass crude drugs were of good quality, while red ginger did not meet the acid-insoluble ash and volatile matter content requirements. The combination showed the highest TFC in a 75:25% ratio, while that of TPC was 50:50%. All combinations of lemongrass and red ginger extracts inhibited MDR Staphylococcus aureus and Candida albicans with a minimum inhibitory concentration (MIC) of 0.16 mg/ml. Candida albicans were more susceptible to the combination extracts. Red ginger rhizomes and lemongrass leaves 75:25% and 50:50% ratios showing comparable effects to the respective components. Hence, the combination of red ginger and lemongrass in 75:25 and 50:50% ratios potentially developed further for their masuk angin efficacy

Increasing Artemisinin Content on Artemisia Plants Through Endophytic Bacteria Inoculation as An Effort to Support the Availability of Malaria Drugs : Peningkatan Kandungan Artemisinin pada Tanaman Artemisia Melalui Inokulasi Bakteri Endofit Sebagai Upaya Mendukung Ketersediaan Obat Malaria
Get PDFIn 2020, malaria cases worldwide increased from 219 million cases to 241 million cases with 627 thousand deaths. This creates problems in terms of the availability of malaria drugs. In addition, resistance to Plasmodium sp. against the commonly used malaria drug chloroquine is another problem. Therefore, in the treatment of malaria, combination-based treatment with artemisinin is highly recommended. However, there are obstacles in the production of artemisinin because its content in plants is relatively low. Therefore, this research aims to increase artemisinin content using endophytic bacteria. The method used is a factorial design with 2 factors, namely Accessions (Green & Purple) and endophytic bacteria concentration (0%, 1%, and 2%). Endophytic bacteria isolated from artemisinin plants were first cultured in a nutrient-rich medium to increase their population. Then, they were inoculated by spraying them twice a week for two months with each accession in each treatment combination. The results showed that inoculation with endophytic bacteria had the best concentration in increasing artemisinin content, namely 1% in green and purple Artemisia accessions. Artemisinin inoculation of 1% was able to increase artemisinin by 27.85% compared to control plants in green Artemisia and purple Artemisia accessions with an increase of 32.89% compared to control plants. The best concentration of endophytic bacteria in increasing artemisinin content is 1%

Get PDFThe comic Sri Asih which was produced after the screening of the film Sri Asih, is an innovation in de-ecranization research because de-ecranization tends to focus on changing the vehicle from a film to a novel. The selection of this object was based on the researcher\u27s interest in the character Sri Asih, who is the first female superhero in Indonesia and is no less great than foreign superheroes, as well as to appreciate the new genre of Indonesian cinema that is packaged in the Bumilangit Cinematic Universe. This research aims to describe the characterization of Sri Asih in the film Sri Asih by Upi Avianto and the comic Sri Asih by Rizqi R. Mosmarth and Dody Eka. The research method used is a qualitative descriptive method. This method produces descriptive data originating from personal speech. The intertextuality approach and de-ecranization studies are used to analyze the structure of the film and comic Sri Asih, which focuses on analyzing the plot, setting, characters, and characterization. Meanwhile, the study of de-ecranization serves to add and change variations in the comparison of the two works. The results of the research conducted show that the film and comic Sri Asih both have superhero themes and use a forward plot as a component to form the storyline. Meanwhile, other building elements in the two works are relatively the same. As for the form of transformation from the film Sri Asih into the comic Sri Asih, there are additional variations and changes
