Currently the pineapple leaf paper that is produced by using local wisdom is 50 centimeters wide and 64 centimeters long. Therefore the product of the Cooperative is small. And because the size of the paper is limited they cannot be used for producing room divider big umbrella or big painting as per customer’s demand and the members of the cooperative cannot produce large sheet of paper. The researchers therefore designed the Pineapple fibrous leaf sieving Equipment in order to produce large sheet of paper. The equipment consists of a square basin for washing leaf fiber sized 185 centimeters 10 centimeter deep with a 90-centimeter high stand to support the basin and installed the mechanism to lift up the sieve that is used to take up the pineapple leaf fiber. The sieve is 150 centimeters x 150 centimeters which is the largest size possible because the leaf fiber washing must is done by hand. If the sieve is bigger we will not be able to reach to the leaf fiber in the center. Base on the experiment of pineapple leaf paper production by using the new equipment as compared to the paper production as per local wisdom by using 2.5 kilograms pineapple leaf fiber and the paper thickness shall be fixed at 0.35 millimeters it is found that the production that use pineapple fibrous leaf sieving equipment takes 647 second on average and the production as per local wisdom takes 1421 second on average. In other words the equipment can help to reduce the time in paper production of 774 second or 54 %. Apart from that the researcher produced the paper with different thickness by increasing the pineapple leaf fiber by 0.5 kilograms per one sheet of paper so that there are more options to choose in order to match with various products. The amount of leaf fiber used in the production starts from 3 kilograms to 7.5 kilogram per sheet and the thickness of the paper is from 0.36 millimeters and the thickest paper is 1.2 millimeters thick using approximately 7.5 kilograms of leaf fiber. If we use more leaf fiber for paper production the paper will be overweight and it will be sagging.

This paper describes an aluminum casting jewelry manufacturing because of the current manufacturing costs are higher. Material or metal that is commonly used to cast jewelry is silver which aluminum Alternatives to metal. Melting is There is a close color and surface finish can be beautiful. But aluminum is a material that is cheap has studied and tested. Replacement aluminum casting body jewelry. The temperature in the baking mold before casting to test all five temperatures are 550 500 450 400 350 degrees Celsius then casting body jewelry in the next stage of the research process casting jewelry with the. aluminum to Experimental temperatures used in baking mold casting plaster for the mold temperature of 400 is appropriate. Best of casting jewelry with aluminum. The results showed that there is minimal waste and a 102 pieces of 48 pieces and has a smooth surface. A similar performance to the other materials available. Similar properties

The aims of this study are (1) the adapting of women’s wear in holding inventory to a new product (2) the study of the satisfactions of women who are 25-35 years old in Bangkok about the adapted women’s wear in holding inventory. The tools for study are the questionnaires and the prototypes to accidental survey 302 women who are 25-35 years old in Bangkok and being the members from buying products of Boutique Newcity Public Co. Ltd. The fist of methods sketching of the adapted holding inventories (shirts skirts and pants) with Ruffles Godets and Transfer Printing to selection by the 5 specialists. Then adapting the top 5 selected styles. Finally surveying and analysis of the samples with percentage mean and standard deviation. The result of the study shows that most women from the sampling are single and have education in Bachelor Degree. Their occupations are in private sector with salary range between 10000 –20000 bath. Their favourite shopping place of women’s wear is department stores and buying of top 3 are pants dress and blouse. The first reason for them to buy the products is the interesting design. The overview of adapted products shows skirts are the first favourite with mean value of 3.13. Shirts are the second favourite with mean value of 3.09 and pants are the last favourite with mean value of 3.07. The conclusion of the developed women’s wear are favoured medium level.

The research aimed 1) to develop the product of floral arrangement on pedestal made of Sanoh Hangkai (jointvetch / Aeschynemene Indics L.) with paper mache technique and 2) to study the target group’s satisfaction with floral arrangement on pedestal product made of jointvetch with paper mache technique. The result found that five specialists had a high satisfaction level to the second method of combining jointvetch with tissue from toilet paper. Mean of satisfaction level was 4.00. Fifty people in target group had a high satisfaction level on developing the floral arrangement on pedestal product made of jointvetch with paper mache technique. Mean of satisfaction level was 4.89 4.84 and 4.66. The details were as follows: 1. The specialists satisfied the study of the second method of combining jointvetch with tissue from toilet paper and had the overall comments about its features with the mean at 4.00 (high level). Mean of the material’s tenderness was 4.60 (highest level). The balance of the material was 4.10 (high level). The toughness of the material was 4.06 (high level) and the material’s softness was 3.50 (high level). 2. The satisfaction level of fifty people in target group to the development of floral arrangement on pedestal product made of jointvetch with paper mache technique showed that they satisfied the floral arrangement in rice-grain shaped on pedestal with its highest mean at 4.89. Mean of satisfaction level on the floral arrangement on pedestal with applied Thai style was 4.84 (highest level) followed by the floral arrangement with joss sticks and candles on pedestal which was 4.66 (highest level).
