Abstract

Background: Argumentation skill is a crucial ability to be possessed by students. Argumentation skills can be trained by applying a scientific approach during learning. The implementation of the scientific approach in schools can vary; it is suspected that one of the causes is the accreditation rating. The study aimed to determine the differences in the argumentation skill of high school students based on their accreditation rating. Methods: The research design used is the Ex-post Facto design. The sample in this study was sampled using the purposive sampling technique. Results:  There are differences in students' argumentation abilities between accreditation ratings of A, B, and C. Conclusions: Students' argumentation skill differs between high school students with accreditation ratings of A, B, and C. The difference in students' argumentation skills is caused by differences in the application of the scientific approach applied by teachers in each school.

Abstract

Cocoa plantation waste (Theobroma cacao L.), cocoa leaves are increasingly abundant, with efforts to increase cocoa production by trimming the shape. The Ladongi sub-district in Kolaka Regency, Southeast Sulawesi, which produces the most cocoa beans, is also not spared from this. Cocoa leaves have not been used optimally, even though their phytochemical components have the potential as antibacterial. This study aims to determine the antibacterial activity of cocoa leaf extract (Theobroma cacao L.) against acne-causing  Cutibacterium acnes and Staphylococcus epidermidis. The method used is the disc diffusion method (Kirby Bauer). The results showed that cocoa leaf extract had the potential as an antibacterial against acne-causing bacteria, Cutibacterium acnes, and Staphylococcus epidermidis with respectively the best inhibitory concentration of 25%, 19mm, and 22mm.

Abstract

Background: Acne is an infectious disease that is still a severe problem. The therapy used for acne is the bacterial antibiotic Clindamycin. Still, there is a lot of resistance to these antibiotics, one of which is Staphylococcus epidermidis, so it is necessary to find alternative antibacterial drugs to treat acne. Non-pharmacological therapy often used is jackfruit leaf extract (Artocarpus heterophyllus L.) which contains secondary metabolites such as flavonoids, saponins, and tannins, which are thought to be effective as antibacterial agents. Methods: The type of research used is True Experimental with the Posttest-Only Control Group research design. The research method used healthy diffusion and liquid dilution, and then the data were analyzed using ANOVA. Results: It was found that jackfruit leaf extract (Artocarpus heterophyllus L.) had antibacterial activity against Staphylococcus epidermidis with a diameter of inhibition zone at a concentration of 50 ppm of 11.7 mm, a concentration of 75 ppm of 12.1 mm, a concentration of 100 ppm of 12.3 mm and had a minimum inhibitory ability at a concentration of 50 ppm with a p-value of 0.007 in the Kruskall-Wallis Test and the Mann Whitney Test showed a p-value of 0.025. Still, the extract did not have the minimum killing ability. Conclusions: Jackfruit leaf extract can only inhibit the growth of Staphylococcus epidermidis bacteria but cannot kill the growth of these bacteria.

Abstract

Background: In Indonesia, the use of herbal plants in overcoming several health problems shows a fairly high rate. Red ginger is one of the herbs that is widely consumed and empirically has the property of relieving or reducing inflammation. However, as is well known, in general the microbiological contamination of herbs is quite high. To maintain the quality of herbal plants, special treatment is required, to ensure that microbial contamination is within safe limits. This study aims to determine the effect of gamma irradiation on the number of microbial contamination, and the bioactive content of 6,8,10-gingerol; 6-shogaol in 70% ethanol extract of red ginger, and its activity as an anti-inflammatory. Methodes: Samples of 70% ethanol extract of red ginger were irradiated with various doses of 0, 5, 7.5, 10 and 15 KGy. Microbiological contamination is determined in Total Plate Number and Yeast Mold Number. The content of compounds 6,8,10-gingerol and 6-shogaol was observed by high performance liquid method and their anti-inflammatory activity was observed by protein denaturation inhibition (BSA) method. Results: Gamma irradiation at doses of 0, 5, 7.5, 10 and 15 KGy reduced microbial contamination as the exposure dose increased, and did not affect the levels of bioactive 6,8,10-gingerol; 6-shogaol and its anti-inflammatory activity. The anti-inflammatory activity of 70% ethanol extract of red ginger is influenced by the content of bioactive compounds. Conclusion: Gamma irradiation is effective for decontaminating microbiological contaminants, and improving the quality of red ginger, and does not affect the bioactive levels contained and its anti-inflammatory activity (in vivo).

Abstract

Background: The COVID-19 disease caused by the SARS-CoV-2 virus has diverse symptoms, ranging from asymptomatic, mild symptoms such as flu-like illness and pneumonia to acute respiratory distress syndrome, which ends in death. Until now, the mechanism of the COVID-19 disease that causes widespread symptoms and the severity and factors that influence it are still unclear. During viral internalization, it needs to be cleaved by the serine protease encoded by the TMPRSS2 gene. It is hypothesized that higher expression of the TMPRSS2 gene causes higher virus internalization into cells, leading to more severe symptoms in patients. Methods: The Single Nucleotide Polymorphism Genotype Test was carried out to prove whether the TMPRSS2 gene affects the severity of COVID-19, as evidenced in other viral respiratory diseases. With a better understanding of gene expression related to this disease, it is hoped that we can better understand the mechanism of COVID-19 and establish better therapies and prevention against it. In this study, 68 COVID-19 patients participated and were categorized into two groups based on their clinical symptoms, namely mild symptoms without symptoms (n=12) and Moderate-Severe symptoms (n=56). PBMC cells were isolated from the patient. Then the DNA was extracted and used as a template in the SNP Genotyping of the TMPRSS2 rs2070788 gene variant. Results: The results showed that 35 samples had A/A homozygous genotypes, 29 A/G heterozygous samples, and 4 G/G homozygous samples. n=29) and heterozygous A/G (n=23), whereas only 4 were homozygous G/G. In addition, the homozygous G/G genotype was only detected in the moderate-severe group. Conclusions: A more significant number of samples from the asymptomatic mild symptom group is needed to statistically prove that homozygous G/G variants or G alleles are generally associated with the severity of COVID-19 patients.
