Abstract

Fermentation has been used by traditional societies as far back as 6000 AD involving microorganisms such as yeast and bacteria that can convert carbohydrates into alcohol and carbon dioxide. This process is essential for the production of bioethanol produced from agricultural residues. Fermentation testing can be done using raw materials such as tubers, sticky rice, sago, water hyacinth and cassava to produce bioethanol as an alternative renewable energy. Methods This research utilizes 8 articles from national and international literature studies in the last 10 years that focus on the fermentation process to produce bioethanol. Research and development of efficient fermentation techniques is urgently needed to increase the yield and sustainability of bioethanol production, thus becoming an environmentally friendly solution in meeting global energy needs. Keywords : Bioethanol, Fermentation, microorganisms

Abstract

Antibacterials are compounds used to eradicate microbes, especially microbes that harm humans. These antibacterial compounds can be extracted directly from plants, where these extracts contain secondary metabolite compounds that have antibacterial activity. Antibacterial testing is carried out on gram-positive bacteria such as Staphylococcus, Streptococcus and others. The method used in this research was a literature study of 10 national and international articles published in the last 10 years. The articles cited focus on research articles on plants that have the potential as antibacterials of several gram-positive bacteria which include extract solvents, metabolite compound content in extracts and their activity capabilities based on the diameter value of the inhibition zone and/or minimum inhibitory concentration using the disc diffusion method. Keywords : Antibacterial, Diffusion Discs, Gram Positive, Secondary Metabolites

Abstract

Cancer is one of the leading causes of death worldwide, including in Indonesia. This review explores the potential of various plants as sources of anticancer compounds through secondary metabolite analysis. Plants such as Rosa damascena, Wild Onion (Scorodocarpus borneensis Becc), and Acalypha Indica have been studied for anticancer activity using in vitro methods. The results showed that extracts from Rosa damascena had varying IC50 values ​​against various types of cancer cells, including 16.28 μg/mL in liver cancer cells (HepG-2) and 18.09 μg/mL in breast cancer cells (MCF-7). In addition, Wild Onion showed very strong anticancer activity with an IC50 value of 1.1061 μg/mL in L1210 leukemia cells. Secondary metabolites such as flavonoids, alkaloids, and tannins were identified as key components contributing to the anticancer effects. These findings highlight the importance of further research to develop more effective and safe plant-based cancer therapies. Keyword: Anticancer, Cancer, Secondary Metabolites, Plants

Abstract

Antibacterial agents are substances used to eliminate microorganisms, especially those harmful to humans. These antibacterial compounds can be directly extracted from plants, where the extracts contain secondary metabolite compounds with antibacterial activity. The antibacterial testing is conducted on gram-positive bacteria, such as Propionibacterium, Staphylococcus, and others. The research method employed is a literature review of 10 national and international articles published within the last 10 years. The cited articles focus on studies of plants with potential as antibacterial agents against several gram-positive bacteria, including the extraction solvents used, the metabolite compounds present in the extracts, and their effectiveness based on the inhibition zone diameter and/or minimum inhibitory concentration using the disc diffusion method. Keywords : Antibacterial, Diffusion Discs, Gram Positive, Secondary Metabolites
