This objective of this research is to study the development of the pararubber tapping knife in order to determine the optimum of the edge and oblique angle and to compare the efficiency of the electrical motor and Je-Bong knife. The product was manufactured by iron steel carbon S45C and AISI 5160 with 75-90 degree edge knife and 0-45 degrees oblique angle. The results can be concluded that the optimum condition of the edge knife oblique knife and the cutting force were 75 degree 45 degree and 3.51-51.42 N respectively. It was found that the cutting force was straightly increased form 0-51.42 N and then gradually decreased. The energy consumption of timber cutting was 0.00370 J/mm3. The quality of the rubber tap using electrical motor was 72.07% which was higher than 2.8 of Je-Bong knife. As the results this product shows the average of rubber timber which is 2.22 mm. in 22.51 s.

The purpose of this research were to 1) study the production factors and efficiency of fireproof suit; 2) analyze the three line balancing models of fireproof suit; and 3) make comparison of production efficiency for fireproof suit’s manufacturing processes. A group of representative sample for assessments is 90 dressmakers of Creative Polymers Co. Ltd. The used tool for collecting data is the data recoding form consisting of production process list data recording date processing operation and duration of processing. Accordingly put the sewing line layout and make production test with the three line balancing models of fireproof suit then record all data and entry all data to SPSS program to average statistics on percentage and standard deviation. The research showed that the improvement of the three line processing models of fireproof suit comparing to the data of the three line balancing models are identified that C model increased from traditional production system 74.05 percentage B model increased from traditional production system 57.51 percentage then A model increased from traditional production system 48.53 percentage. The result showed that the fireproof suit’s production processing of Creative Polymers Co. Ltd. ought to take the C model in order to fasten production process and augment better quality. A minimum process of producing is amount of 110 steps with less time per one unit; minimum 177.41 minutes; with 30 workers; and 27 machines. The waste product of the three line processing models: A B and C model; not over 20 percentage during 8 hours of working. It shows that the c model has the least of waste product. The over operation that product has not much wasted not include in choosing the model for improving production efficiency and C model

The objective of the research is to study and develop a shock and impact absorber material. This material are make from papaya stem and to be used in glass and ceramic packaging. This research is also focus on recycling agriculture waste 1.to added value 2.minimized waste and trash and 3.support the idea of saving the environment and improve economic in community. The process of making this shock and impact absorbing material started with setting the papaya stem in to a frame shape and use natural bonding such as rubber to keep it in that shape. After that it become a shock and impact absorber sheet. The researcher chose six items as case study and they are; tall glass short glass glass doll small cup vase and ceramic doll. All these six items had to go through a standard packaging test and a satisfaction questionnaire. Papaya stem after it has been treaded and soaked in water it become a net like material and bond well with the natural bonding material. In this case it was rubber. After it dry it is soft enough to be used as glass and ceramic items yet strong enough to pass all the packaging test. These shock and impact absorber material performed well with the test and the satisfaction questionnaire and receive high score on the test in both the design and the function.

This research studies the wisdom crafts in Central using vetiver grass is the main material designed by researchers studied weaving in combination with cutting new product development which can take as a model to develop products accordingly. the project is the initiative of his Majesty the King. The study forms the products from grass found from interviews with design professionals. Concluded in the production and design of the model the researchers examined the experts as appropriate. The researcher has taken the form of furniture decorative home modifications. Manufacturers can actually formed. Survey forms about home furnishing 30 which follows. The front living An average of 4.6 more convenience average of 4.6 more security average is 4.75 the design average of 4.7 more overall satisfaction is at the highest level

This research aims (1) to study the added value of the package of leftover concept of the creative economy (2) the concept of packaging designers from residues that can affect the attitude of consumers (3. ) to analyze the development trend of packaging residues. The samples used in research The research sample was divided into two groups. The first sample packaging designers from the establishment of private companies and industrial packaging and printing 20. The samples of two academic staff at the university. And design professionals in the packaging industry and related government agencies. The study concluded that: 1) study the need packaging that require packaging to protect the product from damage. Unique and engaging. 2) to design and develop a packaging structure. Not to damage prevention. Attraction and unique.
