การผลิตกระดาษทำมือจากหญ้าชันกาด
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.

This research aims at studying the product development from Cattail flower paper for community economy by (1) studying the paper making process from Cattail flower (2) testing the efficiency of the paper made of Cattail flower (3) studying the product development process of Cattail flower paper and (4) propagating the knowledge on product made of Cattail flower paper for the community economy to the Women Group for Basketry Product Development in Laem Phak Bia sub-district Ban Laem district Phetchcburi province. The process of paper making from Cattail flower in its mature stage uses soda method in pulping process and hydrogen peroxide in bleaching process. Paper formation process has to be done on grate by (1) using 38 kilograms of fresh Cattail flower which requires pulp separation from the core of Cattail flower providing; 34.2 kilograms of fresh pulp considered as 90%—its average humidity at 51.04%; 3.8 kilograms of fresh core considered as 10% of the total weight (2) boiling in open system at 100 ºC for 3 hours with sodium hydroxide with the intensity at 4% 6% and 8% of its weight (3) bleaching with hydrogen peroxide with the intensity at 10% 20% and 30% of the weight of dried pulp; 2% of sodium silicate; 0.05% of magnesium sulfate; and 1.5% of sodium hydroxide at 100 ºC for 2 hours with the ratio of pulp and water at 1:15 (4) making paper with Thai traditional handmade method with the size of 72×84 centimeters then drying paper in indoor place in order to prevent paper contraction due to short pulp. The efficiency of the paper made of Cattail flower shows that the paper has average standard weight at 168.88 g2/m; average tensile strength at 26.40 N.m/g2; average tearing strength at 3.14 mN.m2/g; average bursting strength at 1.37 kPa.m2/g; average folding strength at 605; average luminance at 39.05%; average water holding capacity of dry weight at 395.65%; and total used bleach pulp at 69.90% of the bleached amount. The product development from Cattail flower paper has 3 types which are designed evaluated and suggested by the experts in accordance with the requirement of community on product development as follows: (1) Paper made of Cattail flower with various patterns; (2) Multi-purpose box made of Cattail flower and; (3) Flower made of Cattail flower paper. During 2 days of the training program the satisfaction of the 30 participants concerning the knowledge on product made of Cattail flower paper for the community economy of the Women Group for Basketry Product Development in Laem Phak Bia sub-district Ban Laem district Phetchaburi province shows that the participants who answer the questionnaire are extremely satisfied.

This research 1) to study and analyze the relationship between the context of industrial handicraftsproperties of agricultural waste in community areas and 2) to agricultural waste to find physical properties and the industrial handicrafts for Bantumsua community Phetchaburi province. From primary data it was found the relationship of the community with the context of industrial crafts is a culture of agricultural wisdom from the collection of participatory research data. Found method and test the properties of paper pulp from agricultural waste where banana leaves = A bamboo leaves = B and pineapple leaves = C.Use the formula for quantifying the triangular grid the Trixie Blend Diagram to uses caustic sodium hydroxide 10-15% of dry weight. There are 7 test items 1 formula thin and thickness (a) according to the experimental standard referring to the community product standards plant fiber paper. For testing as follows: 1) standard average weight from the test of paper size 45x85 cm operation number list of the experimental formula test section 1.1) standard weight the overall average is equal to 220 grams/sqm. 1.2) part 2 tear strength which is strong = 3(10a) at 1962 mN the second strength = 1(8a) at 1907 mN and third = 6(13a) at 1467 mN. 1.3) Part 3 the overall moisture content of the paper the experiment found the humidity level is within the normal level at ± 10% which is complete and can be developed into a products or package. 2) Summary of physical properties the color characteristics of the paper according to provide color tones gray-brown and different beautiful suitable for the screen-printing and using large size rubber stamp. Process forming can produce use by semi-automatic heat setting at 140°C at time of 70 seconds per piece is suitable for further expansion to create industrial handicrafts for the community.

The objective of this paper was to study and development of rice straw paper and development of rice straw paper products-making. Part I. Rice straw paper-making. The bleached and unbleached with 2% HP2(aqJform rice straw fiber was boiled with 2% and 4% NaOH(aq) The 4 treatment was take out container and spread in to thin piece of paper. The 4 treatment were conducted to test physical properties and strength properties on rice straw paper. Part II Rice straw paper products-making. The populations in this research were 16 students and 16 teachers on RIT. Chotiwet Campus to making and evaluate the rice straw paper products. The instrument used in this research were questionnaires about the admission on specifics properties of rice straw paper products and satisfaction to rice straw paper products. The data were analyzed by SPSS program. The statistic used that mean standard deviation one way ANOVA and two way ANOVA. Differences between various groups were tested by Scheffs method.
