Abstract

Currently, the availability of commercial timberand the price decreases the more expensive, efforts are needed to optimize the utilization ofwood. One of the efforts to optimize use of wood can be done by utilizing the rest of sawn timber which has a small and short pieces into a form of veneer for the manufacture of composite floor boards. The purpose of this study is to calculate the efficiency of implementation and product prices of composite floor boards from wood waste material processed, the resulting product ofthe floor boards that can display a charming visual impression. Making the floor boards made of three models: model 1 in the form of composite laminated beams made from composite wood waste processed, and then sliced into several layers of floor boards; model 2 in the form of three layers of combined board cross between layers; model 3 in the form of a thick sheet board (as bottom layer) and on the top layer of veneerare arranged crossing. The results obtained by optimizing the utilization of wood waste processed in terms of technical and price more optimal processing using model 3.

Abstract

Concreteis amixture ofportlandcement,fine aggregate, coarse aggregateand waterwith orwithout additives. Palmshells are hard enough with a lot of surface rupture to beable toreplace thecoarse aggregateonconcreteproperties, especially fornonstructuralconcrete.Combinationof materialconblock concrete of 60 % palm shelland 40% sand using water-cement ratio 0.4 and 0.45 showedstrength 4.0MPa(Muhammad Shalahuddin, 2012).Mixingconcreteis done byDOEmethod,60 samplescylindricaldiameter of 15cm andheight of 30cm. Compressive strengthof concretetestedat 28 dayswith a variety of water-content ratio and a variety of coarse aggregate-palm shells.The greater the percentage of use of the palm shell, made of concrete compressive strength decreases. Concrete compressive strength decreases with increasing of water-content ratio. Variations palm shell 50% and 50% of crushed stone with water-content ratio 0.4 and 0,45 produces compressive strength above 12.5 MPa.
