Water Hyacinth Yarns and Their Transformed Materials Dyeing Machine for Developing Small and Medium-Sized Enterprises was a research project what an aim for producing a prototype dyeing machine. The machine was used at the small enterprise in Nakhon Prathom province. The dyeing machine was contributed by stainless steel. The outer dimension was 100 centimeters in height 130 centimeters in length and 90 centi-meters in width. The inner structure contains with perforate stainless steel drum. It had diameter as 80 centimeters with 90 centimeters length. The container capacity was 27 liters for the raw material as 10 kg of the dry Water Hyacinth Yarns or 5 kg of the dry Water Hyacinth roots. The machine was running test for reactive dyeing process at 80oC for 30 minutes. The machine was achieved for reduce time operation as 5 times and gas consumption as 2.38 times. The break-even point was 1.09 year and B/C as 2.22. Moreover it can solve the fuzzy yarns problem and the volatile smoke during the tradition dyeing. The knowledge was transferred to the stakeholders at the target area as “Chumchonjaksanpaktobchawha Bann klongnokkratum” enterprise in Nakhon Pra thom province. They were satisfied in this benefit in good to very good level.

The aims of this research is to study the suitable ratio of substituted okra with star gooseberry by standard recipe of Production of Crispy Okra Sheet by Hot Air Oven Dryer (Nipaporn and Arrada 2015) was applied in this product. The ratio between okra and star gooseberry are 50 : 50 40 : 60 and 30 : 70 of total weight then selection and nutritional analysis. Furthermore to study using drum dry and belt drier as a prototype for small and medium enterprise (SME). The result showed that the ratio between okra and star gooseberry at 40:60 (w/w) was the highest score of appearance color flavor taste texture and overall liking. The seasoned star gooseberry baked sheet product had total Energy 3 7 2 .0 9 and Energy from fat 47.61 kilocalories/100 gram. Protein Fat Carbohydrate Ash and Moisture content were 14.70 % 5.29 % 66.42 % 7.83 % and 5.76 % respectively. The using belt drier for being dried at 170 oC for 42 minutes was the optimize condition for as a prototype for SME in the future.

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 objective of this research was 1) to learn about the vegetables of students at grade 4-6 rajini school. 2) To study the consumption habits of students. 3) To study the consumption of students. 4) To study the relationship between knowledge. And vegetable consumption habits of students. 5) To study the relationship between attitudes And vegetable consumption habits of students. The Methodology: Participants were 254 study is that students grade 4-6 rajini school. The instruments were Test your knowledge about vegetables have the confidence of 0.68. A survey on the attitudes of confidence 0.72. And a questionnaire about dietary habits and vegetables have the confidence of 0.69. The results indicated that 1) Knowledge of the consumption of students at grade 4-6 rajini school. Most of the knowledge of good and moderate level of 30.71 percent. 2) Vegetable consumption habits of the students were at a very good level (x ̅= 2.35). 3) Vegetable consumption habits of the students were at a good level (x ̅= 2.14). 4) The relationship between knowledge attitude and vegetable intake of students at the grade 4-6 rajini school are interrelated. But there were statistically significant at the 0.05

Nowadays an automotive industry steadily has been growing and playing a major role on economy development for many years. The crash box is one of the most important parts for safety but it was found that the crash boxes manufactured domestically are not met international standard requirements. This is due to process and material limitation. This process for automotive safety test requires high budget and there is unclear approach for specific test. Therefore a study of crash boxes referred to energy absorption project was conducted as the alternative materials for product. Consequently this project was aimed to design and test crash boxes which made from the diversity of the alternative materials such as aluminum aluminum reinforced by foam resin reinforced by fiberglass resin reinforced by water hyacinth and resin reinforced by water hyacinth and husk. In addition it was also emphasized in studying energy absorption behavior and physical deformation of crash boxes after dynamic and static energy being applied. The experimental works were applied for these tests in partly referenced to US NCAP and ECE R29 standard for automobile collision test. Testing all types of crash boxes indicated that the aluminum reinforced by foam type was able to absorb energy at 189 MJ/m3. It is higher than resin reinforced by water hyacinth and husk at 1 MJ/m3 as 188 times. Furthermore the comparison of the energy absorption (per unit volume) between the aluminum reinforced by foam type and the steel type from the previous project equivalent 20 MJ/m3 found that it is 8.45 times of difference. While the front impact test was not successful because the size of crash boxes was not suitable for the energy volume. It was a cause for non-available calculation of energy absorption value.
