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)

This research aims to study the using oil palm fiber to develop ceiling board product. The mixture ratios of Gypsum plaster: oil palm fiber: tap water: catalyst are 1 : 0.15 : 1: 0.03 1 : 0.20 : 1: 0.03 1 : 0.25 : 1: 0.03 1 : 0.30: 1: 0.03 and 1 : 0.35 : 1: 0.03 by weight. The ceiling board samples are cast in 30 x 30 x 1 centimeter in dimension. The ceiling board sample testing follows the TIS 219-2552. The results show that the longitudinal and lateral breaking load Nail pull resistance density and thermal conductivity of ceiling board with high quantity of oil palm fiber are lower than ceiling board with low quantity of oil palm fiber while that the deflection and water absorption of ceiling board with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 0.2 of ratio can pass the standard.

This research aims to study the using oil palm fiber to develop pseudo-plywood from polyethylene product. The mixture ratios of oil palm fiber : polyethylene are 50 : 50 55 : 45 60 : 40 65 : 35 and 70 : 30 by weight. The pseudo-plywood samples are cast in 30 x 30 x 1.5 centimeter in dimension. The pseudo-plywood sample testing follows the TIS 966-2547. The results show that the density bending strength modulus of elasticity thermal conductivity and tension perpendicular to surface of pseudo-plywood with high quantity of oil palm fiber are lower than pseudo-plywood with low quantity of oil palm fiber while that the water absorption and swelling by density of pseudo-plywood with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 65 of ratio can pass the standard.

This research aims to study the using oil palm fiber to develop cement-bonded fiberboard product. The mixture ratios of Portland cement type1: fine sand: oil palm fiber:tap water: catalyst are 1 : 1.95 : 0.05 : 0.40 : 0.03 1 : 1.94 : 0.06 : 0.40 : 0.03 1 : 1.93 : 0.07 : 0.40 : 0.03 1 : 1.92 : 0.08 : 0.40 : 0.03 and 1 : 1.91 : 0.09 : 0.40 : 0.03 by weight. The cement-bonded fiberboard samples are cast in 30 x 30 x 1.5 centimeter in dimension. The cement-bonded fiberboard sample testing follows the TIS 878-2537. The results show that the density thermal conductivity bending strength modulus of elasticity and tension perpendicular to surface of cement-bonded fiberboard with high quantity of oil palm fiber are lower than cement-bonded fiberboard with low quantity of oil palm fiber while that the water absorption and swelling in water of cement-bonded fiberboard with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 0.06 of ratio can pass the standard.

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.
