The results of this research . The result is a Dan Kwian clay. In the study were formulated clay all 3 formulas contain ingredients such different kaolin borax feldspar and dolomite by using theoretical triangle (Trixial Blend) to find the ingredients and the results obtained in the experiment can make clay . Clay qualification in variety usage such as well forming less wrinkle non-crack strong and colourful as requirement. Every recipe is Dan Kwian is the main ingredient for proper implementation of the Community Dan Kwian. The coating experimental in this research there were 2 glazing formulas burn in the temperature of 1000OC-1050 OC in the gas Kiln and wood kiln and the coating colour experiment with the mixed of oxide and stain by using the Line Blend theory. The colour value random from the experiment resulted which were 2 glazing formulas differed which was beautiful and the differed proper character usage. The study found that Can bring the knowledge and methods of the experiment to use in the production Dan kwian actually. As a further development of the local pottery. To create a new form and add value to the product. Can generate more revenue and resulting in a much stronger community.

This experimental research was to test a performance of flat-plate solar collectors using biodiesel as a working solution with a solar thermal system. The purposes were to promote a biodiesel use as an alternative fuel for higher efficient heat energy and as an added renewable energy for a production process and to provide a guideline in education and for development in the future. The experiment was to test a performance of flat sheet solar collectors using ASHRAE STANDARD 93-2003 and to test a thermal potential of 12 litres by volume of biodiesel in a 2 m2 flat- plate solar collector used as heat source of the system. Thus biodiesel was used as a working solution with a flow rate of 2.4 litre per minute and the test duration was between 09:00 am. and 03:00 pm. The result revealed the performance values of the flat-plate solar collector used in this experiment as FR( ) = 0.958 and FRUL = 15.02 W/m2K. The temperature of biodiesel in the solar thermal system increased from 33๐C to approximately 80-90๐C varied with solar radiation values. However; the mentioned degrees could be efficiently applied in biodiesel production process as a main heat source or a supplemental heat source depending on appropriate variables.

The purpose of this research was to construct the Computer Assisted Instruction Package for Computer Instructional Package for Drawing 2 dimension Subject using subject by evaluating the efficiency of the Computer Assisted Instruction Package Tools used for this research were Computer Assisted Instruction Package for Drawing 2 dimension Subject using multimedia quality test and questionnaire for learner’s satisfaction. The sample group was 30 students from Department of Machine Shop Pratumtani Technical College. The analysis between pretest and posttest was learning achievement higher scores This could be concluded that the computer self study package for Drawing 2 dimension Subject using can be used as a learning package.

One of major missions of Rajamangala University of Technology Phra Nakorn is to promote studentscreation of research invention and innovation in order to add values to production sector and national academic service. The Promotion of Inventions and Innovations by Young Generation Project has been since 2008 initiated to provide necessary support development of undergraduate students works. The project aims to promote and improve students invention and innovation as well as to encourage national publication. This project has enhanced students professional expertise which would develop into Hands-on graduates. Results of the project were presented at national level and severaltools devices and products had been produced and evidently utilized to improve production process of communities and industrial sector. The 1st Rajamangala University of Technology Phra Nakhon Innovation and Technology Exhibition is another activity that has presented results of the project to public. The activities included an exhibition of students innovations ana technology a forum on Hands-on graduate development and a contest of students works. This initiation clearly corresponds with the mission to promote students creation of innovation in oder to produce hands-on graduates who have curiosity persistence technological expertise and morality in accordance with the university identity.

Objectives of this research are to select concentrated Thai fragrance formula for evaluation by sensory test and quality test using Thai Community Products standard for fragrance and to study consumers’ acceptance. This experimental research used 2 groups of population: 25 specialists and 300 personnel of Rajamangala University of Technology PhraNakhon. Methods used for analysis in this research were sensory test products standard test and questionnaires. Statistical analysis included Percentage Mean and Standard Deviation. Results found Thai fragrance formula 2 received the highest satisfaction when compared with formula 1 3. The evaporation method got higher satisfaction than dried powder method both before and after mixing with water. Overall satisfaction of dissolving 50 g of products in 600 ml of water had the best satisfaction level. The product passed the standard test at very good level Most respondents were female with Bachelor’s degree with civil servant career. The product which had been diluted with water received better acceptance in all aspects than the product which had not been diluted with water. Satisfaction in concentrated Thai fragrance formula had high score because it was easy to use and keep If this product was sold. Most respondents thought that Thai perfume can be used in all Thai ceremonies at the best price of 30 Bath.
