This Research is to Study the Development of 6k White Gold Low Alloys Metal for Jewelry Production The Optimum Conditions for Casting Jewelry and Jewelry were Investigated. The Results of the Experiments Show that the Chemical Composition of the 8k White Gold Low Alloys is Slightly Different when Compared with XRF (X-ray Fluorescence Spectrometers) Pre-and Post-Melting Quantities The Heat of the Test Specimen was found to be 33.33%Au+50.67%Ag+10%Cu+5%Zn+1%Sn33.33%Au+50.67% Ag+8% Cu+7%Zn+1%Sn and 33.33%Au+50.67%Ag+8%Cu+8%Zn+0%Sn It is Found that the Heat from the Beginning to the Level of Change before the Liquid is used the Average Temperature of 458.9 – 326.3 Degrees Celsius Respectively 33.33%Au+50.67%Ag+8%Cu+7%Zn+1%Sn It is the Formula that Gives the Lowest Value of Liquid State Change from 326.3 Degrees Celsius to the Best Value of this Experiment. Suitable for use in the Manufacture of Jewelry due to its Melting Ability for Molding. Melting for Molding and Formed by Hand. The Amount of Zinc(Zn) may be an Important Factor in the Variation which is Directly Proportional to the Maximum Increase in the Final order of 7 Percent

Based on the research on creation of bas-relief molds for production of bas-reliefs made from boiled pineapple leafs conducted by Rachadasak Pengcum of which purpose was to help generate income for members of Pineapple Leaf Paper Community Enterprise Ban Pasang Wiwat Mueang District Chiang Rai Province it was found that the bas-reliefs need further improvements in terms of appearance and durability as well as the use of other natural raw materials to produce them. The researcher therefore has considered developing the previous research by applying other 3 valueless natural materials which include rice straw water hyacinth and banana stem skin to make bas-reliefs for different beautiful surfaces of the products. Also the quality of bas-reliefs has been comparatively investigated by surveying satisfactions of members of the Community Enterprise and visitors to the project towards the bas-reliefs made from rice straw water hyacinth and banana stem skin. The total period of questionnaire distribution was 3 months. There are 59 respondents administering the questionnaires most of whom (43 persons) are female which accounts for 72.88 per cent. The majority of the respondents (25 persons) obtained junior/senior secondary school diplomas or equivalent accounting for 42.37 per cent. 16 respondents or 27.12 percent are 60 years of age. As for satisfactions towards the bas-reliefs made from rice straw 89 times of “strongly agree” was selected whereas 126 times of “pretty much agree” 75 times of “fairly agree” and 5 times of “disagree” were marked by the respondents. Concerning the bas-reliefs made from water hyacinth 87 times of “strongly agree” was selected while 97 times of “pretty much agree” 110 times of “fairly agree” and 1 time of “disagree” were chosen. When asked about the bas-reliefs made from banana stem skin the respondents selected 77 times of “strongly agree” 99 times of “pretty much agree” 110 times of “fairly agree” and 8 times of “disagree”.

This research presents a bamboo chopsticks machine with automatic control system. The production of bamboo chopsticks the current will be cut to get the machine to enter the bamboo chopsticks using the machine. The machine will hammer bamboo rotation of the electric motor. The AC motors with high power. Currently the production of chopsticks mostly small businesses. Lower costs which resulted in lack of effective security. This research presents the design and techniques with bamboo chopsticks production automation. The objective is to make the production of bamboo chopsticks are secure and compliant. To increase productivity and reduce the danger of the machine. In designing the Arduino technology is used in the development of electronic prototypes designed to be user for both hardware and software advanced application control equipment used in the production of chopsticks for safe to use on the incidence of danger from the use.

This research is a study on the Development of Paper and Packaging from Rice Husk and Rice Processing Wastes for producing for Thai Art Conservation. This research purpose to develop products and packaging from the rice husk in rice processing to study the processes of paper production and forming products to design and develop products and packaging and to transfer technology products and packaging from the leftovers in rice processing to conserve Thai arts to the community and to study the satisfaction of the product and packaging development program from the leftovers in rice processing in order to conserve Thai arts to the community. The research findings can be summarized as follows: 1. In this research the research team produced paper and molded products experimenting with the ratio of RICE HUSK and paper SA fibers and find the best ratio of rice husk 50: paper SA fibers 50 so that rice husk can better adhere to paper and creates a beautiful texture for making products. Moreover this research uses the waste from the rice processing process it able to develop products according to objectives. At the same time can be produced at the household level. As well as finding marketing methods for new products to be able to sell which generates income for the community. 2. The results of the physical characteristics of paper produced from rice husk paper with the ratio of rice husk 50 to 50 has a moderate weight. The paper can be folded. The tensile strength of the paper is moderate. The surface is good. The characteristics of the paper after coated with waterproofing it was coated with natural extracts and environmentally friendly. When testing the water color paint on paper the water color slowly absorbed but does not spread along the paper fibers and also slightly absorbed in the backside paper. 3. In this research the development of products and packaging from the leftovers in rice processing for preserving Thai art into 2 categories 1. Develop paper from rice husk for processing into products and developing molded products from rice husk consisting of 3 sets of ornaments consisting of necklaces bracelets earrings 4 sets of home decor consisting of pans wall paintings and 3 sets of household items consisting of 4 multipurpose boxes fruit trays altar table 4. The knowledge transfer by organizing a workshop for theoretical and practical work the duration of knowledge transfer was 2 days 50 participants between 11 - 12 august 2019 at Bang Tachong Community Enterprise Village No.8 Tha Ngam Subdistrict and District in Buri Sing Buri province. Most participants are satisfied with the highest levels in all questions.

“The Development of Decoupaged Lanna Pattern Bamboo Curl Folk Craft by Ban Rong Don Chai Community in Sarapee Chiang Mai of Thailand” research project’s objectives are 1) To design Thai Lanna pattern for decorates the decoupaged bamboo curl folk craft 2) To survey the decoupaged bamboo curl folk craft customers satisfaction 3) To provide the knowledge and technology on Decoupaged Lanna Bamboo Curl Folk developing The research instrument is a target satisfaction survey which has been analyzed on descriptive statistics . Studied and designed unique Lanna patterns from 3 important religious places of Chiang Mai- Wat Pra Singha Woramahawihan Wat Duang Dee and Wat Chedi Luang which has their own different outstanding Lanna art. 1) Splendid stucco art from Wat Pra Singha Woramahawihan 2) Finely wood carving art from Wat Duang Dee 3) Brilliant Lacquer and gold leaves art from Wat Chedi Luang Woramahawihan Their outstanding Lanna art has inspired a new design which has developed to use for decorating the Lanna bamboo curl folk craft such as home decor souvenirs and home utensils. 25 targets of the satisfaction survey have been impressed on “The Development of Decoupaged Lanna Pattern Bamboo Curl Folk Craft by Ban Rong Don Chai Community in Sarapee Chiang Mai of Thailand” research project. Considering on each field- subject curriculum design expert materials facilities value and utility got the highest impressions scores. The overall averages also shows that every fields got the impression score on ‘most satisfied’
