World Health Organization has declared COVID-19 as the global pandemic. 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.

This study aims to test the model whether attitude towards, subjective norms, perceived behavior control in the theory of Planned Behavior have a positive influence on entrepreneurial intentions and behaviors of private university female students in Klaten Regency. 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.

Along with the trends of healthy lifestyle in which many people are attentive with their own medical condition, public become more actively check their health. 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.
随着健康生活方式的趋势，许多人关注自己的健康状况，公众变得更加积极地检查自己的健康。特别是目前有Covid-19大流行。医学检查可由检验科提供。这项研究是在位于三宝垄市的Meditest临床实验室进行的。本研究旨在根据Fred R. David的定义为Meditest制定竞争战略。本研究使用的数据是主要类型，通过采访负责Meditest运营活动的人员收集，例如Meditest的所有者、经理、采购部门、营销部门和实验室分析师。然后，对数据进行处理，从第一步使用外部因素分析和内部因素分析开始，下一步是IE矩阵和SWOT矩阵，最后是QSPM。研究结果表明，Meditest可以采用的合适策略是市场渗透。营销和推广需要更加密集和频繁，特别是使用流行的社交媒体平台，使Meditest被更多的公众所知。此外，需要考虑更新一些感觉过时的实验室设备，用最新技术的设备代替，以便提高对患者的服务质量。

This research refers to the advantages of a bicycle dynamo over an electric bicycle, namely its ability to save fuel. 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.
