This research aims to study the physical and chemical properties of Cha-nee durian rind powder and using durian rind powder to replace wheat flour in brownie cakes at 1020 and 30% (w/w). Texture profile chemical composition and sensory evaluation of brownie cakes were analyzed. The results showed that durian rind powder contained 50% of dietary fiber. Brownie cake with durian rind powder showed significant decreasing of lightness (L*) and hardness while green-red component (a*) blue-yellow component (b*) toughness and cohesiveness values were significantly higher than the control sample (p<0.05). Proximate analysis of the products showed that brownie cake with durian rind powder had dietary fiber higher than control brownie cake sample significantly. At 30% replacing of durian rind powder brownie cake showed 18.2% increasing of dietary fiber as compared with the control sample. The acceptance score including appearance color odor flavor texture and overall scores of all samples in this study were not significant different. Results indicate that 30% of durian rind powder replacing wheat flour is appropriate for making brownie cake. Brownie cake with durian rind powder could be an alternative for food choice of healthy bakery product which are lower calorie (123.73 kcal per serving) and high amount of dietary fiber (6.37 g per serving). Moreover durian rind powder can be used as a food ingredient and source of dietary fiber in other food recipes for further study.

The purpose of this study were to conduct and to evaluate the effectiveness of Automotive service technician The research procedure starting by collect and study document : research paper international occupational standard (Oklahoma Department of Career and Technology Education) and competency needed in Motorcycle Mechanic suggested by 7 person who working in this field. All data will be referred for behavior objectives list and learning materials design such as information sheet practice operation sheet for experience skill training evaluation sheet with evaluation criteria which clearly listed topics. The sample group in this study was 19 PAJAMANGALA UNIVERSITY OF TECHNOLOGY PHRANAKHON Faculty of Industrial Education in academic year 2 0 1 7 . Pre-test will be given before training steps according to the manual. The students will do the test after each training topic. At the training end Post-test will be given and student final assignment will be evaluated by 5 experts. The Pre-test and Post-test scores will be statistical mean difference test. The research results found that the student final assignment competencies evaluation in percentage mean score was 87.55/94.66/85.13 that higher than 80/80/80 about the expectation. The test percentage mean score after training each topic was 92.11 that higher than 90 about the expectation. The percentage mean score difference test between before and after training was significant at statistical level .01 and the after training score was higher than before training score.

This project aims to create the model of fire protection system for the kitchen. The model installed of protection and notification systems was created by using the Google SketchUp program with a ratio of 1:10 from the real kitchen scale. According to the literature it was found that more than 50 % of the fire within the shelter occurred in a kitchen. The main causes are flame heat sparks and electrical equipment. The system was developed to detect flame gas and smoke by using infrared sensor (IR FLAME) and gas detection device (MQ-2). Arduino MEGA2560 is a central processor to control the device of the protection system. Node MCU is a data receiver with Arduino to display the average amount of gas flame through the Blynk application in real time and send notification via the Line application when the amount of either flame gas or smoke is greater than or equal to the specified quantity. Fire protection system is divided into 3 conditions: fire gas and smoke. In case of fire the sprinkler will be activated with class K extinguishers to extinguish fire. In gas leakage conditions ventilator will be activated to ventilate the gas leaks and the gas supply is cut off. For smoke condition the ventilator will be activated to ventilate the smoke out of the kitchen. The results of the experiment by using the method of dividing into 13 simulations in total. The system can detect the flame with 12 points 92% from 13 points. In case of gas a can of gas was used in all tests. Nine points of gas can detect with 69% of the total 13 points. The smoke detector can capture smoke with a large amount of smoke. There are a total of 13 tests that can capture 11 smoke points representing 84% of all 13 points.

The objectives of this research were to study the effect of hot air velocity on the changes of the moisture content and temperature of preserved tomatoes undergoing combined conveyor system and hot air drying. Specific energy consumption physical properties in term of color and shrinkage and sensory evaluation of dried preserved tomatoes were also investigated. The preserved cherry tomatoes were dried at a drying temperature of 80oc and hot air velocity of 2 and 4 m/s until the moisture contents of the preserved tomatoes were lower than 18% wet basis. The experimental results showed that the hot air velocity had effect on the changes of the moisture content and temperature of preserved tomatoes. Specific energy consumption total color difference shrinkage percentage and sensory evaluation results of dried preserved tomatoes of the hot air velocity of 2 and 4 m/s were not significantly different (P>0.05).Moreover the dried preserved tomatoes obtained from this research had significantly lower sensory scores in term of color and appearance than those obtained from the local market (P≤0.05). However sensory scores in term of flavor texture and overall preference of the dried preserved tomatoes obtained from this research and the local market were not significantly different (P>0.05).

The objectives of this research are to study the production step proper ratio physical properties mechanical properties and thermal insulation of concrete blocks mixed with waste ceramic powder. The ratios of concrete block mixed with waste ceramic powder include Portland cement type1: quarry dust: waste ceramic powder equal to1: 6.8: 0.2 1: 6.7: 0.3 1: 6.6: 0.4 1: 6.5: 0.5 and1: 6.4: 0.6 by weight. Water per cement ratio are 0.6 by weight. The concrete block samples were castedby the general production as same as the ordinary concrete blocks and were tested follow TIS.58. From the results the best amount of waste ceramic powder which put into concrete block is 1: 6.7: 0.3 of ratio. The proper ratios of waste ceramic powder can decrease the density or weight and increase the thermal insulation efficiency of concrete blocks. However the high amounts of waste ceramic powder effect to decrease the mechanical properties concrete blocks that are lower than TIS.58 standard.
