Abstract

The present paper focuses on the first level of possibility associated with the use of the lontar trunk wood (Borassus flabellifer L.), which is used as the biological material in construction work, particularly the correlation between the mechanical characteristics of lontar and its resistance to biological destruction. In this research, the combination of the mechanical and biological characteristics of lontar trunk wood is analyzed, particularly concerning the categorization of structures using factors like modulus of elasticity, modulus of rupture, and the strength when pressed along the grain, and the graveyard test with respect to the weight loss as natural durability criteria. It was found out that MOE varies from 216,042.78 kg/cm² to 269,472.39 kg/cm² for the middle section and 164,402.36 kg/cm² to 181,376.54 kg/cm² for the basal section, while MOR varies from 1,835.75 kg/cm² to 2,764.30 kg/cm² for the middle section and 1,316.70 kg/cm² to 1,779.31 kg/cm² for the basal section. The compressive strength along the grain had values ranging from 304.06 kg/cm² to 775.87 kg/cm², indicating high variation amongst the test pieces. The assessment of natural durability indicated weight loss values of 10.66% to 19.22% in the field graveyard test condition. From the findings above, it is clear that there is great variation in relation to the properties of mechanical and natural durability along the longitudinal direction of the lontar trunk. However, since the test was conducted on one single lontar trunk, it is appropriate to consider the above findings preliminary.
