การพัฒนาเครื่องอบแห้งด้วยไมโครเวฟแบบสายพาน
This research is the study of microwave distribution in the drying chamber to develop the belt-conveyor microwave dryer. The dimensions of the drying chamber are 90 cm width 3 cm length and 30 cm height. Two 800 W magnetrons were installed at the top of the chamber. It was found that the uniform of microwave distribution was observed at the center area of drying chamber. The uniform microwave distribution in the drying chamber at 400 W is achieved. A microwave leakage from the prototype is within the microwave oven safety standard of the US Department of Health and Human Services. This study can be used as a guideline for an industrial design for belt-conveyor microwave dryer.

This research aimed to study students opinions towards the Cheer and Admission Conference and present a creative recruitment model for students of the Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon. The sample group was undergraduate students of The Faculty of Science and Technology Rajamangala University of Technology Phra Nakhon with 376 students studying in 2019. The data collection tools were questionnaires of students opinions on the activities. Cronbachs alpha coefficient was used to examine the whole questionnaires reliability yielding a value of 0.83. A statistical package for analyzing data collected from January to February 2020 was used with the statistics mean standard deviation t-test and one-way analysis of variance (ANOVA). The research results found that: 1. The Pros and Cons of students’ opinions on the freshman orientation activities and cheer meetings were that freshmen get to know friends and seniors; freshmen are afraid of juniors and seniors. 2. Male and female students had different opinions about organizing activities for freshman recruiting and cheered meeting. 3. Students studying in different disciplines had no different opinions on organizing new freshman activities and cheer meeting. 4. Students studying in different year levels had the same opinion on organizing new recruiting activities and cheer meeting. 5. Features of the creative recruiting activities format are as follows: 5.1 It is an activity that gives importance to safety and respect for personal freedom. 5.2 It is the responsibility of the Faculty to closely watch this field of study 5.3 It is an activity that promotes pride in being a student at the university. 5.4 It is an activity that helps students to adjust to university life and aims to foster a good relationship between students seniors and juniors. 5.5 An outside activity must be an event organized by a faculty or university department only.
การพัฒนาระบบปลูกผักไฮโดรออร์แกนิคแบบอัตโนมัติ
Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature pH electroconductivity total dissolved solids mixed liquor suspended solids and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides this system can be easily applied and also very cost-effective for agricultural practice and frequent maintenance every experimental run was necessary.
