Abstract

Background: Air pollution is a threat to the environment. Sources of air pollutants in urban environments can be in the form of dust, heavy metals, and hydrocarbons. Plants can help clean air pollutants from the atmosphere by absorption through the stomata, accumulating them, or by adsorption on the leaf surface. The Air Pollution Tolerance Index (APTI) is used as an evaluation benchmark for the Physiological conditions of plants exposed to air pollution. This research aims to study the physiological conditions of six tree species in air conditions in the Depok City area and to assess the plants' tolerance level based on the APTI calculation. Methods: The physiological parameters measured to calculate APTI were ascorbic acid, total chlorophyll, leaf extract pH, and Relative Water Content (RWC). The six tree species used as objects in this study were Artocarpus altilis, Artocarpus heterophyllus, Bauhinia purpurea, Ficus septica, Filicium decipiens, and Nephelium lappaceum. Results: Differences in the physiological conditions of six tree species in the Depok City area based on the average ascorbic acid values, total chlorophyll, leaf extract pH, and RWC. In addition, there are also differences in APTI parameters between the two research locations. Conclusions: Filicium decipiens is the plant species with the highest APTI, while Artocarpus heterophyllus has the lowest. Based on the APTI scores, Bauhinia purpurea, Ficus septica, Filicium decipiens, Nephelium lappaceum belong to moderately tolerant category, Artocarpus altilis belongs to an intermediate category, Artocarpus heterophyllus belongs to sensitive category.

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.

Abstract

Background: The learning process emphasizes students' active involvement and is oriented towards applying the concept of learning by doing and prioritizing personal experiences through observing, asking, and communicating to increase student creativity. However, reality proves that the application and implementation of learning in schools are not as expected. Some problems include the learning process only focusing on completing the subject matter, not on forming an understanding of the subject matter for students. This study aimed to analyze the need to develop electronic teaching materials according to the needs of students based on problem-based learning (PBL) learning models in biology subjects at MAN 1 Palembang school. Methods: The research used a qualitative descriptive method with a survey method by conducting interviews and questionnaires with biology teachers and students. Questionnaires, observations, and interviews provided data collection techniques. Results: The results obtained are textbooks and learning videos are the teaching materials most often used by teachers using discovery learning and project-based learning (PjBL) models. Students' activeness can be seen when the discussion activities and presentations of assignments take place, but it does not make students think critically. Conclusion: Teachers want problem-based learning (PBL) electronic teaching materials so that students can learn the material earlier and improve learning outcomes in material that is difficult for students to understand.
