Abstract

Coconut wood has been used as an alternative building material for traditional wooden house in North Sulawesi, Indonesia. The performance of coconut wood for building purposes is related to its properties. The objectives of this research are to examine physical and mechanical properties of coconut wood and to identify the strength classes of coconut wood as wooden house elements. This study was conducted with the experimental method by examining its properties including the density, compressive strength parallel to the grain, and bending strength. Based on these properties, the wood strength class was determined by referring to Indonesia National Standard (SNI) 03-3527-1994. The results showed that the density for coconut wood ranged from 0.95 g/cm3 to 1.02 g/cm3. The compression strength ranged from 452.17 kg/cm2 to 564.04 kg/cm2. The bending strength ranged from 328.22 kg/cm2 to 480.13 kg/cm2. According to these results, the coconut wood can be classified as I to IV strong classes. The results indicated the possibilities of coconut wood as wooden house elements.
