Abstract Milk ice cream is the one of most popular dessert in many countries. But the most milk ice cream contain high amounts of sugar and fat. It is for this reason that consumers who exercise regularly concern about the impact of ice cream consumption on health and have led to a considerable rise in high protein and low sugar ice cream demand for this consumer group. Therefore the objective of this study was to develop the reduced energy milk ice cream by using chicken breast and inulin. Milk ice cream was supplemented with chicken breast at 5 10 and 15% by total weight. The result showed that 10% chicken breast ice cream was highest score of sensory evaluation. Sugar was substituted with inulin at 25 50 and 75% by weight. The result showed that the replacement of sugar with 50% inulin was suitable for ice cream. The chicken breast ice cream with inulin formula were determined the physical properties. The result showed that viscosity overrun texture and melting rate of the developed formula were 147 cps 41% 11780 g force and 6% respectively. The lightness (L*) redness (a*) and yellowness (b*) value were 88.68 4.60 and 19.11 respectively. The proximate compositions moisture and protein content of the chicken breast ice cream with inulin formula were 68.03 and 11.79% higher than basic formula whereas fat and ash content of the chicken breast ice cream with inulin formula were 6.02 and 0.45% lower than basic formula. Microbiological quality of the chicken breast ice cream with inulin formula were in the acceptable limit according to Notification of the Ministry of Public Health. In addition the total energy of the chicken breast ice cream with inulin formula was lower than basic formula. The cost of the chicken breast ice cream with inulin formula was higher than basic formula at 16.23%.

The purpose of this research was to study the temperature of burning surf clam shell for soil quality improvement. The experiment was divided two parts 1) the study of the optimum temperature for calcium oxide production by burning 800 900 1000 and 1100 °C 2) the study of using calcium oxide to improve soil qualities of acidic soil and saline soil. The parameters used in the analysis included elements of soil particles soil moisture pH conductivity total content nitrogen phosphorus and potassium. The results showed that the optimum temperature for the production of calcium oxide was 1100 °C since it provided the highest calcium oxide content of 90 % by weight. After applying calcium oxide into acidic soil the composition of soil particles was changed from sandy clay to sandy clay loam. In contrast the soil particle was not changed but the proportion was changed in saline soil. It was also found that calcium oxide reduced soil moisture and influenced the acidity of soil by increasing the pH from 3.39 to 6.92 in acidic soil and 6.49 to 9.11 in saline soil. In addition it was found that the electrical conductivity of the soil was related to salinity. In acidic soil the conductivity of before and after inputting calcium oxide were 0.87 and 1.24 dS/m respectively. In the case of saline soil the conductivity of before and after improvement were 14.37 and 18.80 dS/m respectively. Besides it was found that the total content of nitrogen phosphorus and potassium were reduced after the experiment.

This art thesis aims to design and develop packaging for Healthy CoconutProducts of Lumnam tha Jeen Housewives Group Nakhon Pathom. Which consists of designing and developing the packaging structure graphics logo and shelves. The problem founded in the interview with the entrepreneur was that the packaging still lacks the identity that attracts attention the information on the packaging also shows the details of the product is not complete and the structure is inconvenient to transport or carry among foreign tourists. The present packaging is a wooden basket in some countries must pass an examination in timber imports. The operation has 4 steps as follows: 1 )Interview the entrepreneurs and study the relevant documents and research 2) Design and develop the packaging 3) Bring the expert questionnaire for 3 persons and 4) Design evaluation Data analysis using summary information finding the frequency percentage and average and presented in the form of treatise and composition tables. The results of the research concluded In the structure of packaging shampoo conditioner hair serum hair shower gel and body lotion that have been evaluated as the highest (4.70) looks like a circular cylinder the bottom is wide chasing the size until the top small which brought the concept from the coconut tree. The portable packaging structure includes the products of shampoo hair conditioner shower gel and body lotion that are rated as the highest (4.75) the shape is flat easy to carry and the outer contour line from the coconut tree. The logo has been evaluated as the highest (4.15) uses the golden ratio principle to create recognition. Highest rated graphics (4.50) Use gradient green color mixed with brown which comes from the color of the coconut giving the feeling of using natural ingredients. The form of the shelf that has been evaluated as the highest (4.63) looks like a large podium on the top has a shelf for the product the size height of the shelf is in the eye level of the consumer.

The objective of this study were 1) to develop the gas detector unit for installation on Drone and 2) to test the operational sensitivity of the developed device. The development steps included designing complying the electrical circuit testing the electrical system and online connecting system. Besides the operational sensitivity of the developed device was tested comparing the Gas Alert Micro 5 IR the reference gas detector device both in the laboratory and the field site. The results showed that the developed gas detector could detect carbon dioxide carbon monoxide and methane and displayed the results via Line notification every minute. Additionally carbon dioxide detection by MG-811 sensor gave the results similar to the reference device by 95 percent of significant level with the average amount of detected carbon dioxide in the laboratory and the field site were 700-915 ppm and 138-399 ppm respectively. However the measured results of carbon monoxide and methane from the develop device were relatively different to the reference device. Further study on carbon monoxide sensor and methane sensor calibration are recommended.

This study developed the cemented tungsten carbide by steadily sintering at 1430 °C for one hour. The tungsten carbide structure is a long shape. Its grain size has a difference between width and length and there are high distribution of sizes and shapes. In comparison with the work piece which has the similar size of grain structure the milling duration of tungsten carbide is less even though the condition of WC-Co is the same (95% WC – 5% Co). When the sintering of 1400 °C with the identical milling duration is performed. It turned out that both grain structures of the tungsten carbide and the work piece are similar and their grain sizes are slightly different. However when the grain structures are almost the same and sphericity is increased the hardness and wear resistance will also be improved. Therefore the size of grain structure between 1.00 – 3.00 μm with the milling duration of 100 hours will provide a work piece that has a wear resistance according to international standard
