This research was on the production of hardmetal from recovery of tungsten carbide tool scraps recycling through ball milling for 40 hours. The metal powder obtained which was of the size between 0.11-0.22 µm was composed of 96.69% of tungsten carbide (WC) 1.68% of tantalum (Ta) 1.21% of titanium (Ti) and 0.42% of niobium (Nb). When mixed with 5-15% cobalt binder metal cold isostatic press (CIP) sintered at 1450 ° C it became hardmetal work piece dimension 12.39 x 13.82 x 5.60 mm with 1410 HV hardness and 14.34 g/cm3 density. The result of S45C steel turning was tools life good. The research concluded that the hardmetal work piece produced by the developed material had suitable basic specification and would lead to the development in working in the future.

The researcher constructed a Thai Dessert lesson plan on Kanom Chan (Layer Sweet) leading to creative economy for vocational certificate level 2 the objectives of this research are to 1.Construct a Thai Dessert lesson plan on Kanom Chan (Layer Sweet) leading to creative economy for vocational certificate level 2 that has the efficiency standard of 80/80 2.Compare the achievement of learning of the learner before and after learning and 3.Assess learning behavior about the creativity in the area of psychomotor domain and effective domain of the learner after studying. Target group or population for this research is the 15 Foods and Nutrition students who study Thai Dessert on Kanom Chan (Layer Sweet) leading to Creative Economy in the second semester of 2011 vocational certificate level 2 Thonburi Vocational College. Tools for this research are the constructed lesson plan. The result of the research is shown that the efficient of the Thai Dessert lesson plan for Kanom Chan (Layer Sweet). leading to creative economy is 87.61/83.00 which is higher than the standard 80/80. The achievement of learning of the learner after the studying is higher than that of the beginning at statistical significance of 0.01. The level of the learners learning behavior psychomotor domain and effective domain is good.

This research studies the potential for using waste ash from industrial and agricultural by-products as a plastering material. This paper presents a study of the water requirement compressive strength flexural strength normal consistency setting time and air content of plastering material containing classified fly ash (FA) and ground rice husk ash (RHA). Fine fly ash and fine rice husk ash have a high potential to be used as a good pozzolanic material. The use of finer pozzolan results in a stronger and denser mortar which is due to better Q!spersion and filling effect as well as an increase in the pozzolanic reaction. Fine fly ash and fine rice husk ash can be incorporated into mortar as replacement of the mortar mix cement for the plastering. Mortar mix cement containing 20% fine fly ash and fine rice husk ash can be used to make plastering materials.

Development Project of Application of germinated brown rice in Thai deserts aimed to develop 3 kinds of Thai dessert recipes and process which consisted of Bua loi Frozen Taohuay Lot Chong (A traditional Thai dessert consisting of rambutans in coconut sauce). The result was found that Bua loi Frozen from germinated brown rice was developed by using germinated brown rice and water for Pre-Gelatinization ratio at 2:3 and sticky rice was at 30 gram. Bua loi Frozen at -18 C was thaw in microwave at 70 power 2 minute. The product tested was accepted moderately. The result was found found that Taohuay from germinated brown rice was developed by using germinated brown rice and fresh milk ratio at 100:0 and stability was agar. Taohua tested was accepted moderately. It was found that the product was accepted and there was statistically significant difference at p< 0.05. Lot Chong from germinated brown rice was developed by using germinated brown rice 60 percent and Time for Pre-Gelatinization at 30 minute. Shelf Life Study of Bua loi Frozen at 4 mouth. Taohuay in refrigerator at 1 mouth the product was separate and Lot Chong in refrigerator at 2 week the product was rancid smell and decay to not accept from consumer.

Development Project of Thai dessert products for export industry aimed to develop 5 kinds of Thai dessert recipes and process which consisted of cereal bar instant peanut paste powder instant fried banana flour Kratong Thong (Golden Thai Pastry Cups) adapted for keeping longer and instant Kanom Krok flour (Coconut Rice Cake). The result was found that cereal bar from black sticky rice was developed by using 2 % high-fructose syrup and 12% glucose syrup and total soluble solid of syrup was at 90 Brix. The product tested was accepted moderately. Instant peanut paste powder recipe development made by Miss Suphannika Kosum was tested for sensory evaluation to compare with other peanut paste produced in marketplace. It was found that the product was accepted and there was statistically significant difference at p< 0.05. The five sensory overall liking attributes (colour smell taste texture and total impression) were 7.83 7.76 7.73 7.63 and 8.03 respectively. The product had high preference score. Instant fried banana flour recipe development was done by using rice flour to wheat flour ratio at 120:20 12.5% baking soda and 0.5% calcium chloride. Water requirement was 200 milliliter. The product was accepted at medium to high level. The second recipe of Kratong Thong (Golden Thai Pastry Cups) was the most accepted because it was golden yellow and smooth and stir frying for 1.3 minutes. The product was accepted at medium to high level. For instant Kanom Krok flour (Coconut Rice Cake) it was found that 3 recipes of them were significantly different for texture liking at p< 0.05. 100 and 90 gram of rice flour were studied for producing Kanom Krok it was found that there was no statistically significant difference for overall liking attributes (p> 0.05). Because of indifferent quantity of flour Kanom Krok was slightly different. However Kanom Krok made by 90 gram rice flour was less firming when compared to 100 gram rice flour and the product quantity obtained was also less. There was no statistically significant difference for overall liking attributes. The researcher transferred this knowledge and technology to the target private organization. The first time held on “Thai Dessert Products Course” in Lopburi province between 12-13 May 2008. The result of the technology transfer was found that 80 % of the participants’ satisfaction was accepted and after the course was finished the target groups applied this knowledge and technology for their careers to increase community’s income. It is regarded that this project was accomplished according to its success in the goal and objectives.
