ANALYSIS OF COMPRESSIVE TEST ON THE SAGO WASTE COMPOSITE BOARD

Composite board made from sago pulp waste has been made which aims to utilize unused waste into a more useful and value-added material, in addition to reducing the use of wood as the main ingredient in making furniture. The adhesive used for the manufacture of composite boards is epoxy resin. For 1 composite board sample with a size of 18 cm × 25 cm using a mass of sago pulp 320 grams with 10% adhesive mass so that the adhesive mass used is 10% × 320 gram = 32 grams, with a ratio of 16 grams of epoxy resin and 16 grams of epoxy hardener, the adhesive concentration used is 9%. The crude fiber of sago pulp mixed with epoxy resin is then pressed hot for 1 hour at 100 ° C at a pressure of 10 kgf / cm² and cold pressing is carried out for 48 hours at a pressure of 10 kgf / cm². To determine the mechanical properties of the sago pulp composite board was carried out through a press test. The results of the tests that have been done obtained a fractured modulus value of the sago pulp waste composite board of 1322.82 kgf / cm2 and the largest force that can be retained by the composite board before deformation is 21982, 51 kgf.
