The purposes of this research were to developed the tea Product from Ya Nang Melientha suavis and safflower. The objective was to study the optimum drying conditions of Ya Nang tea leaf and Melientha suavis 2) to study the optimum ratio between Ya Nang tea leaf and Melientha suavis and Safflower in the tea formulation and 3) to study the acceptance of Ya Nang tea products with Melientha suavis and safflower flowers from consumers It was found that the suitable drying time of tea leafe was 4 h at 60o c with moisture content lower than 10% that was in agreement with standard. The proper ratios between Ya Nang Melientha suavis and Safflower such as 100:0:0 60:20:20 60:30:10 and 60:10:30 were evaluated the sensory properties by 30 panelists. It was found that the highest acceptability sure was found in formulation 3. In addition the DPPH radial scavenging activity and phenolic content were 66.51 μM Trolox/ml and 14.46 mg GAE/ml respectively for the accepted tea formulation. For the consumer test (120 consumer) the data relating to product interest acceptability and antioxidant properties were 59.20% 96.70% and 75% respectively. This results indicated that tea Ya Nang Melientha suavis and Safflower is accepted by consumer.

This research aims to develop the natural rubber and ethylene vinyl acetate (EVA) plastic floor tile with flame resistance property. The 6 ratios of natural-rubber STR 20: zinc oxide: stearic acid: sulfur: mercaptobenzothiazole: diphenyl guanidine: EVA plastic: antimony trioxide were equal to 100: 5: 2: 3: 0.5: 0.2: 20: 0 100: 5: 2: 3: 0.5: 0.2: 20: 20 100: 5: 2: 3: 0.5: 0.2: 20: 40 100: 5: 2: 3: 0.5: 0.2: 20: 60 100: 5: 2: 3: 0.5: 0.2: 20: 80 and 100: 5: 2: 3: 0.5: 0.2: 20: 100 by weight or phr. The samples are ground by two-roll mill and formed by compression molding at 150 degree Celsius with 30x30x0.2 cm of dimension for 4: 29 to 5: 19 minutes. The properties of the natural-rubber floor tiles were tested under ASTM standard. From the results it was found that the natural rubber and ethylene vinyl acetate plastic floor tile with flame resistance property was the suitable ratio for using as the rubber floor tiles in building and extinguished a fire by themselves. The antimony trioxide effected to increase the density hardness and thermal conductivity and decrease the tensile strength tear strength and wear resistance properties of the natural rubber and EVA plastic floor tiles

Currently the automotive industry plays an important role on the economic growth in Thailand. As the same time the waste of automotive parts has increased as well. As a results the automotive parts made from three different natural fiber parts was studied consisting of hyacinths sugarcane and pineapple leaf fiber. By of 50 x 250 x 20 mm of mold dimension the specimens were produced under 700 W of heating stick and measured temperature by a K type of thermometer. There were 3 same proportion specimens made from: 1) sugar cane fiber: husk: latex adhesive 2) water hyacinth fiber: husk: latex adhesive 3) pineapple fiber: husk: latex adhesive in the ratio of 25:25:50 by weight which were formed under temperature between 100GC and 105°C at 5 MPa of pressure and leading to find out the bending moment ability. The test results show that the specimen made from sugar cane fiber has the highest value 5482.5 Nand 4061.11 N/mm2 of bending moment and bending stress respectively. It was more than specimen made of water hyacinth 29.84 % and pineapple fiber 65.01 %.

The purposes of the research were to 1) study the attributes of the graduates according to standards of learning outcome 2) study the 21st century skills of English for International Communication graduates desired by employers 3) compare the attributes of the graduates according to standards of learning outcome categorized by the individual factors and 4) compare the employers’ requirements to skills of English for International Communication graduates categorized by the individual factors. The population were 55 employers participating in the cooperative education project in the academic year 2017. The research tools were questionnaires and interviews which were analyzed by the SPSS program. The statistical data analysis was performed by frequency percentage mean standard deviation and Fdistribution and the interview data analysis was performed by frequency and content analysis. The results were found as follows. 1. As for the employers information33emoloyets were from private and service businesses (60%) and 14 employets were from government sectors (25.50%).As for the working statuses29 employers were the officers (53.70%) 20 employer were the supervisors (37.00%) and 5 employers weie mangers (9.30%) 2. The overall requirement of hte employers for the attrbutes of the graduates according to standandards of learning outcome was at the high level (=4.48). As for each attribute morals and ethcs were the most desirable (=4.75) the second highest level was interpersonal skils and accountabiliy (4.57) and the last one was the intellectual skills (=4.25) 3. The overall requirement of the ernptoyers for the 21st century skills of the graduates was at the high level (=4.43). As for each attribute the highest level was enthusiasm collaboration and thinking skills respectivrty (=4.634.58 and 4.54) The lowest tevel was the inquiry skills (=4.07). 4.The results of the research hypothesis were; 4.1 There was a significant difference between the employers with different employrment sectors (government and service business sectors) and the requirement of the graduates attributes. There was no significant difference between the employers with different working status and the requirement of the graduates attributes. 4.2 There is no significant difference between the employers with diferent employent sectors and working status and the requirement of the graduates attributes.

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”.
