This research presents the processing of fresh guava into guava juice product. to be kept for consumption and distribution in the local area It is an alternative career path that helps rural farmers earn more. and create additional careers for the family But farmers still lack the correct technology tools and processing methods in each production process. Therefore there was a problem of insufficient cleanliness taking a lot of time resulting in unacceptable quality and the production is low the postharvest engineering research group has conducted research to find suitable guava juicer. This study is based on working principles of food processing equipment in general use. Come as a guideline to develop improve and create prototypes. The original guava juicer was a grater roller squeezer. There is a guava-sized subsystem consisting of a sub-chamber with grated rollers and the waste water barrier system consists of a juice sieve chamber a waste separation room a spiral conveyer and a sweeper set. various parts that come in contact with the guava juice is made of stainless steel The power source uses a 1-horsepower electric motor a single-phase electrical system a voltage of 220 volts. The machine has the ability to block water at a rate of 250 kg / hour. The juice obtained must be filtered out again with a centrifugal bag filter capable of filtering water at a rate of 50 liters/hour. The prototype guava juice machine costs 40000 baht and the centrifugal filter bag costs 5000 baht. With just one such machine each of these machines can produce 28000 liters of guava juice/year (112000 bottles a year) able to get a return in 0.08 years with an average processing cost of 4.48 baht/bottle which is appropriate in engineering economics. In investment use a ready-to-drink guava juice machine. Fresh guava ingredients are available throughout the year and have 200 business days/year.

This research suggests an add-on working compatibly with Google Forms to construct multiple-choice questions (MCQs). This add-on comprises two main components including software for constructing MCQs and a data storage for collecting data used to compose MCQs. I demonstrated effectiveness of the add-on by applying it in the context of repetition online learning in which students could learn relearn and take an exam of which MCQs generated by the add-on. At the last step of this research I suggest using a sentiment analysis method – based on natural language processing and machine learning to find environmental factors and teaching strategies suitable for the repetition online learning.

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.

During the epidemic of the coronavirus covid-19 single-use plastic containing products were in high demand across the community and may not be cost effective to recycle. However repurposing such materials can reduce their environmental impact for instance plastic foam waste can be made into pots for planting different types of plants and trees. By mixing the foam with a suitable cement in a ratio of 1:1 a large range of pot diameters from 4.5-10 inches can be produced suitable for both indoor and outdoor planting requirements. These pot products suitable for growing plants of all sizes are durable unbreakable water tight. Therefore it is a product that repurposes the leftovers from the community and may even add value. This strategy helps reduce the problem of waste and in particular encourages replenishment of green space to nature and the environment which also helps to combat global warming.

Due to the need for Thailand to adapt and develop its economy to keep up with the changes of the world it has to develop technology and innovations with efficiency in order to drive Thailands economy to prosper and keep pace with the rapidly changing global economy. Therefore it is important that educational institutions can help Thailand to have a good economy that is comparable to other countries is to organize the education system with courses that meet the needs of the enterprises. In addition a new generation of entrepreneurs (Start-up) must be created and developed to have knowledge and abilities to drive the countrys economy to be sustainable and efficient. The new generation of entrepreneurs must have knowledge and ability to use technology and innovation in business operations create added value to the economy and bring Thailand into a high income country and people in the country have a better life. Therefore the researcher aims to find guidelines for the development of the Faculty of Science and Technology. Lets step into the development of technology to promote innovation to create a new generation of entrepreneurs with the ability to operate business by using information technology to drive business progress. The samples used to collecte data were personnel students of the Faculty of Science and Technology and establishments related to the occupation of students in both government and private sectors and the research instruments were 2 sets of questionnaires including the 1st set a questionnaire to survey opinions on the development approach of the Faculty of Science and Technology and the second set of questionnaires for enterprises to explore the need for building and develop entrepreneurs in the new era with characteristics that meet the needs of the establishment. The results obtained from the statistical data analysis are guidelines for the development of the Faculty of Science and Technology in creating a proactive strategy to develop the faculty and up-to-date personnel skills training. Access to technology and innovation to step into a university in technology and promote the creation of appropriate innovations to create and develop entrepreneurs effectively.
