This research aims to study the water hyacinth fiber inside high-density fiber cement 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 with the steel grating inside. By compressing the mixture cast machine at normal temperature (30 - 35 °C). From the test results the ratio of B4 is the appropriate ratio from the 1st year research result to produce the high-density fiber cement board with the steel grating inside 0.81mm #0.5”. It can pass the TIS 878-2537 standard of Cement Board and good based-on high density and physical properties mechanical properties and thermal insulation. Accelerate the formation of the most suitable cement is calcium chloride (CaCl2).

The research was to develop environmental packaging from composite materials hyacinth fiber rice husk and coconut fiber for temperature preservation to replace the use of foam packaging that cannot be degraded naturally. In the composite materials water hyacinth fiber rice husk and coconut fiber at the ratios 7: 1: 2 1 : 1 : 2 and 1: 1: 1 were extruded by heat using isocyanate glue as a solder and testing the physical and biological properties of composite materials as fiberboard. For testing of temperature preservation of the bio packaging heat transfer test to obtain the bio-packaging for the environment the composite materials of fiber water hyacinth rice husk and coconut fiber at the ratio of 7 : 1 : 2 was the most appropriate type. Since it had a density of 0.7 grams per cubic centimeter strength of 26.76 MPa moisture content of 3.8 percent ages and swelling of 26.63 percent ages. In dry condition at room temperature it could store heat for 2 hours and could retain the cold temperature as shown for the temperatures rising from 4 to 30.7 degree Celsius within 2 hours. This research therefore presents a new alternative method of natural fiber composite materials application for temperature preservation in order to reduce the use of foam containers and increase cost value to natural bio waste materials.

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.
