This research aims to study the water hyacinth fiber inside high density cement fiber board. By using ratio components among cement : fine sand : water hyacinth fiber : water : catalyst accelerated the formations of cement (aluminum sulfate (AI2 (SO4) 3) calcium chloride (CaCl2) sodium silicate (Na2SiO3)) on the ratio 1: 0.2: 0.075: 0.3: 0.03 by weight of total water hyacinth fiber. The 5 ratios consist of 0.0 (A1 D1 formulae) 0.025 (A2 B2 C2 D2 formulae) 0.050 0.03 (A4 B4 C4 D4 formulae) and 0.1 (A5 B5 C5 D5 formulae) by weighted all fibers were treated with sodium hydroxide solution (NaOH) at a concentration of 12%. The fiber to solution ratio was 1: 10 boiled in open system at 100 °C for 1 - 3 hours. By compressing the mixture cast machine at normal temperature (30 - 35 °C). Use a density of 0.75 g / cm3. From the test results the ratio B4 is the appropriate ratio. Can pass TIS 878- 2537 Cement Board: high density and physical properties mechanical properties and thermal insulation are good. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2)

The purpose of this research was to investigate cooling water profile that effect to coefficient of performance of spilt type air- conditioning system. Air conditioner size of 12000 Btu/h was used in this experiment. There are three experiment of cooling water profiles in this work such as water spray water drop and heat exchanger profile. The ambient temperature conditions were controlled at 35 40 43 and 45 oC. The results of this study were found that heat exchanger profile had the highest average coefficient of performance and energy efficiency as 4.94 and 9.15 Btu/Wh which increased as 20.1% and 8.47% respectively when comparing with the normal working.

In this study water quality standard of bottled drinking water distributed in Ang Thong Province was investigated. The results showed that clear plastic bottled drinking water presented completely label information and MFD./EXP. clearly appearance and odourless presented in all samples while Total Dissolved Solid (TDS) of tested clear plastic bottled drinking water samples were in a range of 1±0.00 to 277±0.00 mg/L. Coliform bacteria and fecal coliform bacteria of all tested water samples were less than 2.2 MPN/100 mL and E. coli and total heterotrophic bacteria were not found in all samples. pH values of 18 tested samples were less than 6.5 (60.00%) plastic bottled drinking water samples. Tested opaque plastic bottled drinking water samples showed completely label information and MFD./EXP. clearly appearance and odourless found in all samples while TDS of tested opaque plastic bottled drinking water samples were in a range of 12±0.00 to 13±0.00 mg/L. Coliform bacteria and fecal coliform bacteria of tested water samples were less than 2.2 MPN/100 mL and E. coli and total heterotrophic bacteria were not found in all samples. pH values of 3 tested samples were less than 6.5 (100.00%). Indeed assessment of both types of bottled drinking water samples distributed in Ang Thong Province Thailand based on 6 qualities assessment of standard for drinking water in sealed container set by Ministry of Public Health of Thailand revealed that the tested clear and opaque plastic bottled drinking water samples met the standard for 40.00% and 0% based on pH respectively.

The objective of this research was presented a decision support making process for efficiency improvement of drinking water processing using retrofit technique for machine and equipment rehabilitate. This methodology was applied Analytic Hierarchy Process (AHP) for selecting an appropriate maintenance sub-contractor. To complete the research existing water purifying machine and tools were inspected to assess its capacity. Future capacity of the purifying machine was also identified. Consequently machine and tools such as water tank and water filter were inspected for retrofitting for the example water tank water filter water quality control and bottle packing. Finally the analytic hierarchy process was utilized to select the most appropriate maintenance sub-contractor. In this process both qualitative and quantitative processes were analysed. The result of this research has been found that this multicriteria decision making process could be used to support the decision making investment process of water purification retrofit unit at Faculty of Engineering Rajamangala University of Technology Phra Nakorn efficiently. Furthermore it could be reduced bias from decision makers while the decision was accepted by all stakeholders.

The research products of chili fried watermelon rind remains were found. The decent amount enhancing of the watermelon rind in fried chili pastes are 25% 50% and 75% of total weight. The results show the 50% enhancing of the watermelon rind in fried chili pastes all of sample such as roast chili paste fermented fish chili paste Tadand chili paste and Oong chili paste were recognized in the like moderately-like very much. Increase of watermelon rind at 75% of total weight the acceptance is decrease. The texture of samples of fried chili pastes enhancing of the watermelon rind show that 1035.74-1901.16gram of the consistency -132.16- -98.07 gram: milligram of the cohesiveness and 2.15-5.67 gram of the viscosity. The chemical composition of fried chili pastes enhancing of the watermelon rind show that the 50% of watermelon rind in roasted chili pastes were 233 Kcals of total energy 7.20 of protein 9.56 of fat 4.83 of ash 29.60 of carbohydrate and 7.09 of crude fiber. The 50% of watermelon rind in fermented fish chili paste were 152 Kcals of total energy 5.93 of protein 5.60of fat 4.21of ash 19.4of carbohydrate and 5.41of crude fiber. The 50% of watermelon rind in Tadand chili paste were 183 Kcals of total energy 6.68 of protein 3.26 of fat 7.34 of ash 31.80 of carbohydrate and 11.10 of crude fiber. The 50% of watermelon rind in Oong chili paste were 182 Kcals of total energy 6.77 of protein 12.80 of fat 2.61 of ash 9.92 of carbohydrate and 3.21 of crude fiber For the technology transfer of Fried Chili paste from Watermelon Rinds Waste to Center Concert career womens groups Don Kang. The participants were satisfied with the course of 92.67
