Strategies to improve the immune system to prevent infection of SARS-CoV-2 virus need to consider physiological and mental health aspects. Many researches have been discovered that various active components in Indonesian herbal plants may have the potential as immunostimulants and anti-stress which can be used as functional foods. This literature study aims to analyze the strength of scientific evidence related to the effect of polar bioactive compounds in various Indonesian herbal plants on the immune system, cytokines activity and the cortisol hormone to decrease the COVID-19 disease risk. The method used was a systematic review (PRISMA) with evidence-based analysis. This study found 7 types of Indonesian herbal plants which have potential to increase the immune system (CD4+ T cell lymphocytes, CD8+, CD25+, CD68+, B cell lymphocytes, NK cells) and immunoglobulin activity (IgA, IgG, IgE, IgM), lower the activity of proinflammatory cytokines (IL-2, IL-4, IL-6, IL-10, IL-12, IL-13, IL-1β, TNF-α, IFN-γ), help manage stress by suppressing the excessive secretion of cortisol and has anti-inflammatory as well as antioxidant properties.","PeriodicalId":403309,"journal":{"name":"Praxis : Jurnal Sains, Teknologi, Masyarakat dan Jejaring","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114166950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research design was carried out using a quantitative method which explains the causal relationship between one dependent variable which is influenced by three independent variables and one mediating variable. Hypothesis testing is formulated in the model using the multivariate test. The population in the research were all university students in the Klaten Regency area who had started the initial ultra-micro business. The sampling technique was carried out by purposive sampling as many as 180 respondents of female students as initial business actors. The final result of the quantitative model test using Structural Equation Modeling (SEM) shows that there is a positive influence on attitude towards entrepreneurship and perceived behavior control on entrepreneurial intentions and behaviors. Meanwhile, one variable in the form of subjective norms does not significantly influence it. Future research can expand the model through testing the antecedents of intention to behavior by developing research designs through experimental research.","PeriodicalId":403309,"journal":{"name":"Praxis : Jurnal Sains, Teknologi, Masyarakat dan Jejaring","volume":"151 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116092735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially there is Covid-19 pandemic in the present time. Medical check-up can be served by clinical laboratory. This research was performed in Meditest clinical laboratory, located in the city of Semarang. The purpose of this research aims to formulate competitive strategy for Meditest based on definition by Fred R. David. The data used on this research is primary type, gathered by interviewing those responsible to Meditest’s operational activity, such as owner of Meditest, manager, procurement division, marketing division, and lab analyst. Then, the data is processed, beginning from first step using external factor analysis and internal factor analysis, next steps are IE matrix and SWOT matrix, and the final step is QSPM. Result of the research shows that the suitable strategy that can be used by Meditest is market penetration. Marketing and promotion need to be more intense and frequently, especially using popular social media platform so that it makes Meditest to be more known by general public. Also, need to be considered to update several lab equipments that felt dated, replaced with equipments with latest technology, so that those will improve service quality to patients.","PeriodicalId":403309,"journal":{"name":"Praxis : Jurnal Sains, Teknologi, Masyarakat dan Jejaring","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124591345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because this type of vehicle only uses electric current as fuel. Their low prices and similar models of motorbikes ensure that there is no difference between an electric bicycle and a fossil fuel motorbike. Electric vehicles have developed, ranging from two-wheeled, four-wheeled, trains, to carts paired with electric motors that use batteries. The method is done manually and takes the essence of several related references then takes the supporting equations so that it becomes a research innovation in generating a research innovation. Do not forget to also conduct a comparative study of this research with previous research. Research optimization by adding a bicycle dynamo as a generator can save power up to 0.05 What a distance of 300 m. It is proven in research at a distance of 300 m, an E-Bike that uses a bicycle dynamo costs only Rp.4.14 / 300m, an E-Bike that uses a transformer costs Rp.4.2 / 300m. Electric power at a distance of 300 m with a bicycle dynamo consumes 271.59 W while electric power at a distance of 300 m with a step-down transformer consumes 295.02 W, and it is proven that bicycle dynamos are more efficient in consuming electrical energy.","PeriodicalId":403309,"journal":{"name":"Praxis : Jurnal Sains, Teknologi, Masyarakat dan Jejaring","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115696561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
