This research objective was to design the ginger candy compression machine and determine the efficiency and capacity for saving time and labor in pressing ginger candy for community enterprise groups Pim Malaherb Chiang Rai Province. Ginger candy compression machine consists of the main structure namely the extruder and power transmission systems. The machine was designed with two horsepower motors or 1.5 kilowatts to drive the shaft and to rotate the screw through the flange. This study installs the inverter to control the motor speed at 1000±10 1200±10 and 1400±10 rpm. The extrusion die had an average diameter of 9.7 millimeters. The results found that the motors speed that was suitable for compression was a Rotational speed of 1400±10 rpm. When the speed increased the efficiency and the working rate increased too. The amount of ginger stirred was used at 300 500 600 900 1000 1500 2000 and 3000 grams. The maximum efficiency was 90.85 percent. The efficiency increased with the amount of ginger stirred. The ginger candy compression machines engineering economic analysis results found that the machines operating cost was 18063.6 baht per year. When considering the machines operation at 792 hours per year the payback period was 6 months and 11 days.

The objective of this research was to study the development of cake decorated cream without trans fat. selection of buttercream using as a standards recipe from 3 formulas 50 tasters by 9 Point Hedonic Scales Test. The formula using buttercream had 8.37±0.71 points at very like level was composed of butter 36.08 % shortening 15.47 % white egg 5.15 % sugar 25.77 % salt 1.03 % water 15.47 % and vanilla 10 %. Then substitute shortening with white kidney bean at 0 25 50 75 100 %. The 100% white kidney bean recipe was the highest acceptable 8.42±0.75 points at the very like level. The acceptance test with 100 consumers was 8.10±0.74 score at very like. The color of products showed L* a* b* C and H were 37.52±0.04 0.30±0.01 11.19±0.04 11.20±0.04 88.42±0.07 respectively The Viscosity was 2857±26.62 cPs Moisture was 31.78±0.05 w.b. Texture (Firmness) was 55340.06±68.39 g Consistency was 47435.10±376.39 N. and Cohesiveness was 5.30±0.39 g.sec which more than the standard recipe and nutritive values per one serving. Carbohydrates decrease at 0.19 gram Energy increase at 32.43 kilocalories Fat decrease at 1.97 gram Sugar decrease at 30 gram and more protein than the standard recipe with 0.23 gram. per serving at 150 g.

This research aims to analyze demand Necessary Skills and ways of collecting the credit to transfer into the education system of Service Industry Workers (Hospitality and Tourism) in Bangkok. The research results found 4 points that is; (1) career stability (2) knowledge (3) services (4) awareness and self-esteem value During the research process of training course curriculum found that there are three courses that is English training course for hospitality industry Excellent Services technique for customer impressive course using technology “Amadeus” system for booking and ticketing in tourism and hospitality industry. These courses become a set of learning handbook and trained to the target group service working to learn and have knowledge up-skilled and have a positive thinking to work in service industry. In term of earning credit from these courses into the education system in form of transfer credit by using knowledge and experiences the results from research seminar can be conclude into two ways (1) transfer credit from the course that has certificate or do not have any certificate still can transferred within the guarantee from institution (2)transfer credit from certified course should be specify with the exactly total houses studying or have a test and evaluate the learning outcomes from the courses.

Piper Betel has been used as a medicinal herb in Thailand for a long period. Not only consumption but Piper Betal also has been used for religious belief and ritual. However the piper leave should be in the good condition without any defect. As a result there are numerous fall-grade leaves to be get rid of from agriculture. Increasing the value-added of this by- product can increase the income. Extraction of bioactive compounds by using alembic is uncomplicated and green without any solvent is required. Two products come out from this process the first one is an essential oil which is expensive. The second product is hydrosol. The piper hydrosol still contained various phytochemicals. In this study total phenolic content was investigated and was found to be in the range 31.16-73.71 GAE mg/g. Total antioxidant capacity was also studied using the DPPH method. The antioxidant activity was 0. 37▁(+)0.11 mg ascorbic acid equivalent/ ml hydrosol. However the piper hydrosol cannot inhibit P.ance S.aureus and S.epideminis. To sum up the piper hydrosol can be used as an ingredient for antioxidant cosmetics rather than antibacterial skincare.

The objective of this study was to develop the Homemade Black-Sesame Butter recipe. By adapt from 3 basic Peanut Butter recipes by replacing peanut to black-sesame 100% by total peanut weight. And improving the texture (spreading) by added Rice Bran Oil Shortening in 4 different level are 0% 10% 20% and 30% by total product weight. Randomized Complete Block Design (RCBD) was used to evaluate the sensory quality in terms of appearance color odor taste texture (spreading) and overall liking. Recorded the results of the characteristic of Homemade Black-Sesame Butter in the list with description to choose the best formula to get the experimental result. The result showed that the first formula of Homemade Black-Sesame Butter by replacing Peanut to Black-Sesame 100% by total Peanut weight. The characteristics are coagulated appearance matt-black color strong sesame odor medium sweet and the texture (spreading) showed that spread better than another recipe. Therefrom improving the texture (spreading) of Homemade Black-Sesame Butter by added Rice Bran Oil Shortening. The study showed the added level at 30% of Rice Bran Oil Shortening by total product weight of Homemade Black-Sesame Butter. The characteristics are coagulated and sticky appearance glossy black color high sesame odor lower sweet than the previous and very smooth texture (spreading). Homemade Black-Sesame Butter formula ingredients are cooked fine crush Black-Sesame 85% Rice Bran Oil Shortening 36.1% Soybean Oil 3% Powdered Sugar 1.7% Honey 3% and Salt 1.2% by total ingredients weight
