The purpose of research is to study the carbon footprint evaluation of products for thread turned Tungsten Carbide 16ER60 of production. To assess amount of greenhouse gas emissions that affect the environment. The key component in the calculation include raw material production material energy and waste January 2018 and March 2019. The scope of the study is the assessment of Business-to-Business (B2B). From the assessment of the carbon footprint it was total of greenhouse gas was about 1.1559 Kg CO2e which was divided from raw material about 0.0118 Kg CO2e and production process about 1.1441 Kg CO2e. From the improvement reducing electricity of sintering furnaces machine and lighting system was reduce greenhouse gas emissions about 0.3249 Kg CO2e or decrease percent 71.88 CT

This research 1) to study and analyze the relationship between the context of industrial handicraftsproperties of agricultural waste in community areas and 2) to agricultural waste to find physical properties and the industrial handicrafts for Bantumsua community Phetchaburi province. From primary data it was found the relationship of the community with the context of industrial crafts is a culture of agricultural wisdom from the collection of participatory research data. Found method and test the properties of paper pulp from agricultural waste where banana leaves = A bamboo leaves = B and pineapple leaves = C.Use the formula for quantifying the triangular grid the Trixie Blend Diagram to uses caustic sodium hydroxide 10-15% of dry weight. There are 7 test items 1 formula thin and thickness (a) according to the experimental standard referring to the community product standards plant fiber paper. For testing as follows: 1) standard average weight from the test of paper size 45x85 cm operation number list of the experimental formula test section 1.1) standard weight the overall average is equal to 220 grams/sqm. 1.2) part 2 tear strength which is strong = 3(10a) at 1962 mN the second strength = 1(8a) at 1907 mN and third = 6(13a) at 1467 mN. 1.3) Part 3 the overall moisture content of the paper the experiment found the humidity level is within the normal level at ± 10% which is complete and can be developed into a products or package. 2) Summary of physical properties the color characteristics of the paper according to provide color tones gray-brown and different beautiful suitable for the screen-printing and using large size rubber stamp. Process forming can produce use by semi-automatic heat setting at 140°C at time of 70 seconds per piece is suitable for further expansion to create industrial handicrafts for the community.

The potential health benefits attributed to mulberry leaf and its bioactive compounds have led to a huge increase of mulberry leaf products in the food market. The objective of this research was to determine total antioxidant activities ( FRAP and DPPH assays) and polyphenol compounds in 4 snack products i.e. loaf-bread puifai (Thai steamed cupcakes) peakpoon (Green coconut sweet pudding) and snow skin mooncake fortified with 10% mulberry leaf powder from “ Buri Rum 60” cultivar. The result showed that antioxidant activities and polyphenol contents increased in 4 products fortified with mulberry leaf powder. Ferulic acid was the only phenolic compound found in all original products. Kaempferol quercetin and caffeic acid were significantly increased whereas ferulic acid was reduced in the modified formulas. Therefore these bioactive compounds properties of mulberry leaf powder suggested their possible use for fortifying the healthy foods.

The objectives of this research were to construct a jar oven for the production of roasted chicken using heat from far-infrared radiation and to find the amount of electricity and specific energy consumption used in the production of roasted chicken. The physical properties in terms of color softness cooking yield and water holding capacity of roasted chicken were also investigated. By using far-infrared radiation at electrical power levels of 1000 1200 and 1400 watts to roast marinated chicken which had an initial mass of about 1650 grams until the mass of the roasted chicken had a lower than 1220 grams. From the experimental results it was found that the production of roasted chicken at far- infrared radiation with a high electrical power level requires significantly less electricity and specific energy consumption than that with low electrical power level (P≤0.05). Roasted chicken breasts with far-infrared radiation at 1400 watts had significantly higher lightness (L value) but lower redness (a value) and yellowness (b value) than those of 1000 watts (P≤0.05). However lightness (L value) yellowness (b value) and redness (a value) of the roasted chicken breast with far-infrared radiation at 1200 watts were not significantly different from those at 1000 and 1400 watts (P>0.05). The shear force and water holding capacity of roasted chicken were significantly increased when the electrical power levels of far-infrared radiation increased (P≤0.05). Moreover the electrical power levels of far-infrared radiation (1000 1200 and 1400 watts) did not significantly affect the cooking yield of roasted chicken (P>0.05).Sponso

The purpose of this research was to study hot-melt adhesives from natural rubber (Standard Thai Rubber 20 STR 20). In order to improve the adhesion and melting properties of hot-melt adhesive to get the best glue formula from STR 20 the ethylene vinyl acetate content (EVA) paraffin wax (Wax) and petroleum resin (Resin) were varied from 25 50 100 125 and 150 phr (Part Per Hundred Rubber). It was found that the best adhesive formulas consisted of 100 phr of STR 20 25 phr of wax 150 phr of EVA and 150 phr of resin. For preparing hot-melt adhesive first the wax was heated and maintained at 160-170 ºC then cut the STR 20 into small pieces and slowly added the rubber into the melted wax until the rubber was completely melted. And then added resin and EVA and cooled to room temperature finally the results show that hot-melt adhesive was dark brown hard and odorless smooth texture and easy to melt with 514±14 centipoises of Viscosity at 150 ºC 82.49±1.4 lbf/in2 of shear strength and 2.06±0.02 kN/m of cleavage peel strength.
