Panicum repens is a species of grass. The paper has been made from non-wood materials for long times. This research was used Panicum repens for made grass pulp as non-wood fiber. The influence of alkaline concentrations on properties of pulp from Panicum repens was investigated under room temperature. Alkaline concentration levels were varied at 0% 5% 10% 15% and 20% respectively. Moreover Paper pulp from Panicum repens was observed by scanning electron microscope (SEM). This research has controlled the length of fiber approximately 0.5- 2.5 cm before soaked with alkaline concentration at 1 hour and soak with water for controlled pH value at 7-8. Paper pulp was formed on a sieve. The result showed that color of paper pulp made from Panicum repens was light brown and green. SEM showed that alkaline concentration affects the physical properties of paper pulp. Moreover true density of paper pulp was also investigated in this research.

Research development of Funeral Flowers made from Rice Husk purpose To make use of the chaff by making mourning flower products and to transfer the knowledge to the target group. The results revealed Uses of rice husk by making flowers and mourning products from rice husk. All 7 experts have commented on the appropriateness of the clay formulas that will be used to mourn flowers from rice husk Amount 5 formulas. The third formula is most suitable (x ̅4.44) at a high level. Due to the texture of the soil the texture is soft not hard. Can be molded not stick to hands can not be molded before drying Flexibility The texture of the soil is very sticky. Able to knead into a homogeneous texture not separated In balance forming well Does not shrink by hand No cracks And the color of the texture is natural. Then the experts select the characteristics of flowers that are suitable for the wreath. Include Mass flowers experts choose lilly (42.85%) followed by cattleya orchids (28.57%) extra flowers. Experts choose roses (42.86%) secondary Down Plumeria flowers (28.57% equal) filler flowers. experts choose Dok Kaew (28.57%). For the flowers that are suitable for making funeral flowers. Many experts choose roses Plumeria flowers (42.86% equal) filler flowers expert choose (57.14%) followed by grass flowers (28.57%). Choose can be made easily. And is known to the general public From then produce 3 types of wreaths and 3 types of funeral flowers. Knowledge transfer of the flower products from the Rice Husk To the target group in Bang Tachong Enterprises and some people in InBuri District Singburi province Amount 50 people in order to expand the knowledge from the research. Community earn more income .With the use of local waste materials Come to create innovative products. The target group is satisfied with this Product. Overall is at the highest level (x ̅4.50). The satisfaction with the research project arrangement Overall is at the highest level (x ̅4.67) and product satisfaction Overall is at the highest level (x ̅4.64).

The objective of this study was to investigate the optimal formulation of mulberry fruit leather product when varying the weight ratio of mulberry fruit: water as 70:30 60:4050:50 40:60 and 30:70. Three factors were then determined by simplex centroid design; sugar (0-100% or 0-50 grams) citric acid (0-100% or 0-5 grams) and pectin (0-100% or 0-3 grams) which the sum of them equivalent to 100% while other ingredients remained constant. Analysis of the data was performed using ANOVA and Mixture Response Surface Models. The results indicated that the highest adhesiveness force and gumminess of mulberry fruit leather product were founded when the weight ratio of mulberry fruit to water was 70:30. The amount of sugar acid and pectin had effects on water activity (Aw) texture profile and sensory score of overall liking of product. From contour plot the predictive models were obtained by plottin g the contour line of all sensory attributes with acceptable score greater than 5.5 and thus the optimization area was selected. After overlapping contour plots an optimal formulation obtained was composed of 40-70% sugar 0-5% citric acid and 30-55% pectin. The sensory score of overall liking of product using a 9-point hedonic scale was 6.3. The water activity (Aw)adhesiveness force cohesiveness and gumminess of the prototype mulberry fruit leather product was 4.9 945.11 g. sec. 0.85 N and 452.12 N. respectively.

The objectives of this study were to calculate the probability of type I error power of a test and to compare the performance of three test statistics: Z Student’s t and Welch’s t. Including the recommending the appropriate test statistic. Classification of the population according to five distribution. The ratios of mean group 1 per group 2 were three levels. The ratios of variance group 1 per group 2 were three levels. The sample sizes of two populations were nine sizes. The significance levels that to study were 0.01 and 0.05. The data were simulated by using SAS programming with 1000 replicates. Results of the research were Z test statistic could control the probability of type I error and had higher power of a test than other test statistics but this test is necessary to know the variances of the two groups. Therefore it was appropriate to apply the other test statistics i.e. Student’s t or Welch’s t. If the variances of the two groups were equal Student’s t was a more appropriate test statistic than Welch’s t. But if the variances of the two groups were not equal Welch’s t was a more appropriate. When both sample sizes were large and the population variances were equal we could use any tests since there is no difference in the performance.

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)
