Abstract

Background: Arenga vinegar (Arenga pinnata) has been trusted by the indigenous people of Kampung Kuta as traditional medicine, one of which is used as a diabetes medicine. For this reason, the aim of this study is to examine the bioactive compounds contained in arenga vinegar, namely acetic acid, which is predicted to be scientifically proven using reverse docking techniques. Methods: This research is descriptive qualitative research, by interpreting the data obtained from databases and software. Results: There is a binding pose between acetic acid and the sucrase-isomaltase enzyme, the lowest binding affinity value is -3.2 kcal/mol, and the binding site occurs hydrophobic interactions with the amino acids Trp327 (A), Asp355 (A), Ile392 (A), Trp470 (A), Phe604 (A), His629 (A), Trp586 (A) as well as hydrogen bonding to the amino acid Asp(472)A. Conclusions: The acetic acid-binding pose binds well to the sucrase-isomaltase enzyme so that the binding affinity value appears even though the value is not too low and the binding site occurs, this can be used as proof of the belief of the indigenous people of Kampung Kuta, namely the treatment of arenga vinegar as a diabetes drug, especially as a level control blood sugar.

Abstract

Background: CPO refining which produces solid waste namely spent bleaching earth (SBE) in large quantities can pollute the environment. SBE from bentonite ores contains large amounts of silica, so it can be an alternative source of silica minerals. Silica plays an important role in increasing plant resistance and bioactive plant compound products. Methods: The application of Si in plants can increase secondary metabolites such as phenolic and anti-fungal compounds in response to disease pathogens. However, the low solubility of silica makes silica not sufficiently available for plants. Using microorganisms as silica solubilizing bacteria helps increasing solubility of silica in the soil. Bacteria dissolve silica by removing organic acids and producing indole acetic acid (AAI), which stimulates root hairs. Results: This review presents the results of a study on the utilization of silica-rich SBE waste as a source of available silica for plants with solubilizing method using bacteria to increase plant growth and resistance, as well as increase plant secondary metabolite compounds. Conclusions: The application of silica solubilizing bacteria has been known to play an important role in providing silica for plants, through enzymatic mechanisms, namely the production of organic acids and extracellular polysaccharides.

Abstract

Background: Assessment is a crucial step for determining whether or not a learning process has been successful. High-order thinking skills are a requirement for learning achievement in the twenty-first century. The goal of this project is to put quantitative evaluation instruments created by Jakarta elementary school teachers to the test. Methods: A mix method is used, which combines descriptive qualitative research with document analysis and quantitative research with instrument testing on reproductive system material, which is then examined using Anates. The participants in this study were eight Jakarta-based grade VI primary school teachers. Results: It demonstrates that teachers' capacity to construct evaluation instruments varies widely. Testing using Anates shows 15% of the questions compiled are valid and 85% invalid, 1 school with strong reliability and 7 other schools are less reliable. The difference shows that 42.5% are accepted and 57.5% are rejected. The level of difficulty showed that as many as 8.75% of the questions were in the very easy category, 18.75% easy, 51.25% moderate, 7.5% difficult and 13.75 very difficult. These results form the basis of the importance of the hierarchy of teacher understanding in depth, especially in relation to the preparation of HOTS-based assessment instruments because the quality of learning success is largely determined by the assessment instrument used. Conclusions: The LOTS and HOTS-based capability instruments made by the teacher at 8 East Dijakarta Elementary Schools have not been maximized and need development by these teachers.

Abstract

Background: Breadfruit [Artocarpus altilis (Parkinson ex F.A.Zorn) Fosberg] is a versatile plant that can be used by humans. Breadfruit has morphological variations that are thought to be related to anatomical variations that are formed as an adaptation mechanism to survive in a different area. This plant has the ability to live in different altitude ranges, from coastal areas to upland areas. This research was conducted for eight months in areas with altitude ranges of <350 masl, 350-700 masl, and >700 masl in Banyumas, Purbalingga, and Cilacap Regencies. Sampling of plants was carried out randomly selected (purposive random sampling), then described their morphological characteristics. Furthermore, the leaves are made for anatomical preservation to determine the anatomical character. Breadfruit plants that grow at an altitude of less than 350 m above sea level have the characteristics of a higher, larger diameter stem, have a tighter branching, more sap production, a higher number of fruit and have a larger fruit size. The anatomical characteristics of breadfruit plants that grow at an altitude of less than 350 masl have stomata characters that are wider and longer than those of 350-700 masl and > 700 masl. The highest stomata and trichomata density at an altitude > 700 masl. The highest mean cuticle thickness, epidermis, palisade ratio and mesophyll thickness were highest in breadfruit leaves at altitudes <350 masl.

Abstract

Background: Entomopathogenic fungi are one of the potential biodiversity assets to be used as biological control agents. However, information about the diversity of entomopathogenic fungi, especially in the Gunung Tukung Gede (GTG) nature reserve is very limited. The purpose of this study was to provide information on the biodiversity of entomopathogenic fungi in the GTG nature reserve. Methods: The entomopathogenic fungi were explored from 3 different stations: primary forest, secondary forest and disturbed forest. Entomopathogenic fungi were isolated identified both macroscopically and microscopically. Results: A total of 15 specimens of entomopathogenic fungi consisting of 5 families and 8 types of fungi successfully isolate. The entomopathogen fungi were Basidiobolus haptosporus, Beauveria bassiana., Metarhizium aniesophalie, Paecilomyces sp., Aschersonia sp., Aspergillus sp. 1, Aspergillus sp.2, and Septobasidium sp. These fungi infect insect hosts from the orders Lepidoptera, Hemiptera and Homoptera. The index of the diversity of entomopathogenic fungi at 3 consecutive stations is 1.5495; 1.3322; and 0.6365 (medium category). Conclusions: The GTG Nature Reserve has a unique diversity of entomopathogenic fungi. Therefore, further research is needed in order to determine the diversity and potential utilization of the existing entomopathogenic fungi.

Abstract

Background: Melanoma is a skin disorder caused by malignant degeneration of the pigment cells melanocytes. The disease is characterized by widespread discoloration with irregular and protruding edges. In treating cancer itself, radiotherapy technology, has been found. It is a method of treating cancer using high-energy radiation rays that are focused on cancerous tissue to kill or stop cancer cell division. This study aims to determine the effectiveness of radiotherapy technology as a treatment solution for melanoma skin cancer. The focuses of the study in this paper are the integumentary system and skin structure, melanoma skin cancer, the body's mechanisms for melanoma skin cancer, and radiotherapy as a treatment method. Methods: The research method used is literature study from various sources, to help understand the problem more deeply and completely. Conclusions: Melanoma, which attacks one of the body's integumentary systems, namely the skin, has a close relationship with homeostatic dysregulation and endocrine damage. However, radiotherapy method can be used to cure melanoma skin cancer by shooting X-rays and damaging the cancer cells and also reducing their spread to other parts of the organs. This method is effective because melanoma skin cancer is localized or has not spread to other organs. However, the use of radiotherapy can also have a negative impact on the body and can give unwanted side effects, so consideration is needed before using this method.
