The research aims to study the quality of Chaiya salted eggs coated with tea waste to partially replace soil from termite mound. The residue of tea waste dried to a moisture content of 14.9% was used to prepare salt coating paste. It was found that the mixture of coating paste by substitution of termite mound soil with 10% (w/w) tea waste was appropriate to coat the duck eggs. The salt content increased in both egg yolk and egg white with increasing salt coating time. Coating egg with 10% tea waste for 24 days egg yolk contained salt 0.83% moisture 17.04% and weighed 19.19 grams. The pH value and hardness were 6.43 and 93.67 gram respectively. The egg white contained salt 5.27% moisture 81.61% and pH value was 7.60. The salted boiled eggs coated by 10% tea waste treatment for 21 days were accepted by the panelists in terms of the overall liking with the level of much liking (8.67) not significantly different (p>0.05) from that of the control treatment (0% tea waste). Microorganisms in the salted boiled eggs did not excess Thai OTOP standard. A hundred general consumers accepted this product in terms of the overall liking with the level of much liking (8.00).

This research focuses on the production of charcoal briquettes from agricultural residues by using durian and nypa palm peel mixtures. The objectives of this study are to study the combustion efficiency of charcoal briquettes; study the suitable ratio for the production of briquettes with the ratios of durian : nypa palm peel mixtures as 100:0 50:50 25:75 and 0:100; recycle the agricultural residues as the renewable energy sources and analyze the fuel characteristics; moisture content ash content volatile matters fixed carbon and heating value. The results showed that the best ratio for the combustion efficiency of charcoal briquettes is 50:50 with the minimum moisture content of 4.68% the minimum ash content of 2.70% the volatile matters of 10.33% ; the maximum fixed carbon of 25.56% and all characteristics are met with the standard of charcoal briquettes from the local community products. In the ratio of 100:0 it showed the maximum heating value as 5399 calories per gram. Therefore the 50:50 charcoal briquettes are suitable as the renewable energy source. Besides the capacity of odor adsorption was analyzed by adding the odor substances (mothball) in two bottles with three mothballs for each bottle for two consecutive days before removal. Then sic of 50:50 charcoal briquettes were added into one bottle. Ten testers smelled the bottle every two days for six days. The result showed that the bottle with the charcoal briquettes had odor less than the bottle without briquettes. Hence the charcoal briquettes from durian and nyla palm peel mixtures have the best odor adsorption capacity and are suitable for household uses.

This research aims to study the using oil palm fiber to develop pseudo-plywood from polyethylene product. The mixture ratios of oil palm fiber : polyethylene are 50 : 50 55 : 45 60 : 40 65 : 35 and 70 : 30 by weight. The pseudo-plywood samples are cast in 30 x 30 x 1.5 centimeter in dimension. The pseudo-plywood sample testing follows the TIS 966-2547. The results show that the density bending strength modulus of elasticity thermal conductivity and tension perpendicular to surface of pseudo-plywood with high quantity of oil palm fiber are lower than pseudo-plywood with low quantity of oil palm fiber while that the water absorption and swelling by density of pseudo-plywood with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 65 of ratio can pass the standard.

This Research is to Study the Development of 6k White Gold Alloys for Jewelry Production. By Studying the Influence of 6k White Gold Alloys on Physical Properties for Jewelry Molding Process. Of 6k Gold Alloys at Various Compound Rates. The Results of the Experiments Show that the Chemical Composition of 6k White Gold Alloys is Slightly Different when Compared with the XRF (X-ray Fluorescence Spectrometers). Compare the pre and Post-Melting Quantities. The Result of the Compounding Test with the Color Level of 6k White Gold at the Compound Rate 25%Au+54%Ag+0%Cu+3%Zn+18%Pd The Lowest Color Level was L * = 82.14 a * = -0.16 b * = 7.71 and the Lowest Color Difference was 21.07. With other Ingredients It Shows that the Test Specimen of 6k White Gold has a Rather Greenish Color and is Slightly Yellowish Compared to the Blue Line that Approaches the Standard line. These Properties are the Physical Properties Required to Produce a 6k White Gold Jewelry Body.

This research aims to study how to use stones Pumice Products is interlocking block for community development. The mixture ratios of Portland cement type1: sand: quarry dust: pumice rock fragments: water that there are 5 ratios. The products were tested by the community TCPS 602-2547 (2004) (Thai): interlocking block. The results showed that interlocking block of stone pumice much a compressive strength and thermal conductivity under a block of stone pumice less. The water absorption is increased When a block of stone pumice much. The optimum ratio and the use of waste rock Pumice highest ratio of cement to stone dust on the stone Pumice water in a 10: 6.4: 0.6: 0.45 to 10: 6.1: 0.9. 0.45 by weight.
