Analysis of the connection between herd immunity and vaccination uses a model for spreading infectious diseases with injections vaccines in three forms. The results were analyzed using complete graph to determine the relationship of group immunity to vaccination under the three forms hypothesis of vaccinations against the spread of infectious diseases and drawing a graph from Gephi program. The results showed that herd immunity was directly related to the number of people vaccinated. If the number of people vaccinated is high herd immunity will occur. But if the number of people vaccinated is low herd immunity will be difficult.

Garlic is an ancient food and medicinal plant that has been used for centuries. The research team was interested in creating a garlic oil extract that could help reduce microbial contamination in the air during the prolonged period of the COVID-19 situation. A prototype sugarcane leaf paper filter was treated with garlic oil extract to improve its air purification properties and to reduce the number of microorganisms. This study investigated garlic oil extracts that were produced by a garlic fermentation process with isolated lactic acid bacteria. The oil was then extracted using steam distillation or maceration with 80% ethyl alcohol. Both these methods demonstrated that they were effective in inhibiting pathogenic microorganisms contaminating isolated from air (Fungi: Penicillium sp. Aspergillus spp. and Rhizopus sp. and Bacteria: E. coil Bacillus subtilis and Staphylococcus sp.) by Agar Diffusion method. It was found that the garlic oil extract distilled from steam was the best choice for further development as a coating for filter paper. Garlic oil extract can be stored at room temperature for at least 15 days after being coated on filter papers. After that the filters with garlic extract-coated filters made by sewing together four folded filter papers could remove the dust of 2.5 sizes as well as HEPA filters but had a disadvantage in filtering dust that was at least 10 PPM. This paper filter prototype was environmentally friendly because it could decompose on the ground within 12-15 days and reduce the spread of infection problems. From overall the prototype of the garlic oil extraction process can be developed at a commercial industrial level to produce large quantities of garlic extract with desired quality tracking features. It helps reducing environmental problems in a sustainable way; reducing waste conserving energy and using environmentally friendly materials.

Augmented reality or often called for short that AR is technology that exhibits a virtual image in the real world. Currently this technology has been widely applied to the education domain and responded to the development of essential skills to survive in the twenty-first century. AR is used to promote self-learning according to the constructivist theory which believes that learning is a process arising within the learner. Furthermore the COVID-19 pandemic has conducted to the new way of life which is called the “new normal” in which people avoid seeing each other as well as minimize congestion at all places and contact. Therefore this research aims to study the transfer of processes and technologies used for development. About the COVID-19 situation through the virtual world able to transfer knowledge processes to the public Being aware of the COVID-19 situation and promoting lifelong learning

Data visualization technology is going to grow in importance in the short term. This technology is a concept that describes any effort to help people understand the significance of data by placing it in a visual context. Patterns trends and correlations that may go unnoticed in text-based data can be more easily exposed and recognized data visualization software. The purpose of this research is to develop the interactive dashboard of Thai temple data in Nonthaburi province and finding out the users’ satisfaction with the dashboard. The tools used in the research were Data Studio software online questionnaires mean and standard deviation statistics. The results of the overall satisfaction evaluated by participants of 100 users who were people living in Nonthaburi province is at the highest level at a mean of 3.80. Therefore the results of this research can be applied to any Office of Buddhism that face with similar issues of data analytics

In Klong Rangsit Pathumthani province where the water entering was filtered by a prototype quality water machine and autonomously controlled by pumps and sensors this research tested improvements to water quality. It employs a total dissolved solid and temperature sensor as part of the consideration of the water quality criterion in accordance with the water quality requirements of the Pollution Control Department and is 99% successful in treating contaminants in water. According to the Pollution Control Departments water quality criteria which are divided into four main categories: very good water quality good water quality degraded water quality and very degraded water quality it is used in the analysis of the division of the four categories of water quality. Machines for producing good quality water to maintain water sanitation during COVID-19 and anticipated flooding across the nation. This is simple to use. Since the made quality water machine prototype has a battery to back up the power for the pump and UV lamp control by filtering water through various stages of a quality water producer prototype it is simple can generate clean water for usage and can be carried. No energy is used and there is no residue filtration effluent. It eliminates 99 percent of water pollutants and has no color.
