Wood-based product innovation is a means to introduce an innovative wood product that is cheap and light but can be used like other wood products. The use of coconut fiber which is agricultural waste as an alternative material to replace veneer is possible to save wood use. Meanwhile, the use of community wood such as sengon wood is also an effort to replace natural forest wood which has been used in the manufacture of plywood. The combination of sengon wood veneer with coconut fiber will be formed into a hybrid plywood product (KLH). However, this plywood product has disadvantages such as flammable. Therefore, in the development of this KLH product, efforts need to be made to improve these weaknesses, namely by providing fire retardant materials. This study aims to create a plywood product that has the ability to inhibit the rate of combustion so that it can be used as a wall siding or as a partition. This research was carried out on the use of flame retardant material (AF21a) which has the active substance ammonium phosphate with concentrations of 10%, 20%, and 30% which was then smeared on veneer and soaked in coconut fiber for 5 minutes. After the veneer is melted and the fiber is immersed in a fire retardant material, then the two materials are alternately arranged between the veneer and coconut fiber. The arrangement was then glued using phenol formaldehyde (PF) with a weight of 300 g/m2. Next, the arrangement was compressed using a cold press (cold press) at room temperature for 10 minutes, and a hot press (hot press) at a temperature of 150°C, and a pressure of 20N/mm2 for 10 minutes to form a five-layer KLH. Tests are carried out on vertical and horizontal combustion properties using the UL 94 -2001 test standard. The results showed that the application of a 30% concentration of fire retardant to the fiber produced the best results in inhibiting the horizontal fire rate, but at the vertical direction of the fire rate the treatment of 20% concentration of flame retardant immersed in the fiber resulted in good fire inhibition. Other results showed that the application of fire retardation to coconut fiber by immersion showed the highest fire retardant power compared to the application of veneers by means of whitewashing.
