This research to examine the structure and mechanical properties of aluminum dross. A research project knowledge the aim is to study the microstructure and the mechanical properties of materials. The research is divided into two parts: 1 . preparation aluminum dross material and 2. to determine the structure and mechanical properties. The material must be washed in preparation contamination and dry then crushed and sifted to 200 mesh. Analyzed the microstructure with SEM which indicated the microstructure. The amount of alumina in aluminum dross grade No.0 has 8 0 percent with a powder aluminum dross grade No.1 is a hunk with crystalline alumina component 85 percent. Aluminum dross grade No. 2 which is a big hunk has crystalline alumina components 9 0 percent. Analysis results indicates that aluminum dross can be applied to other aspects such as to produce bulletproof vests and so on.

The objective of this thesis is to study 1) To study the selection of standard formulas for recipes of Gub Dessert 2) to study the amount of stevia that used to replace some white sugar in the Gub Dessert products 3) to study physical properties. Carbohydrate content and sweetness in the product of sweets that use stevia water in the replacement of some white sugar and 4) to study the consumer acceptance of Gub which uses stevia instead of some white sugar By using the original recipe of Gub 2 recipes then the recipes derived from the study of the original Gub pastry was used to use stevia water to replace some 4 levels of sugar: 45:55 50:50 55:45 and 60:40 Accepting tests by sensory testers 45 food and nutrition experts sensory evaluation results showed that the use of stevia water to sugar in the ratio of 60:40 was the most accepted. With a significant difference (p≤.05) using the original formula and the modified formula to test the carbohydrate and sweetness values. It was found that the carbohydrate values in the basic formulas were 60.84 grams higher than the modified formula. The sweetness of the basic formula is 92 brix which is higher than the formula and the formula 4 ratio 60:40 which is the most accepted. Going to test the acceptance of 100 consumers with the 9-Point Hedonic Scale preference rating method. Most consumers had a high liking. 2 aspects.

The results of the study revealed as follows. 1. Most of the personnel were males aged between 31-40 years old holding Bachelor’s degrees in the area of production process with 5 to 10 years working experience. 2. Their opinions towards the waste management within the organization were found that the overall picture was rated in the high level in every aspect arranging from the average values of the highest to lowest namely Reuse Recycle and Reduce aspects respectively. 3. The results of the hypothesis testing revealed that the sample personnel of different genders have dissimilar opinions on the waste management within The Government Pharmaceutical Organization on the in the Reuse Recycle and Reduce ง aspects areas with statistical significance at the level of 0.05 and their different educational levels resulted in dissimilar ideas on the waste management within the organization regarding the Reduce aspect at statistical significant at the level of 0.05.
