Pengaruh Jenis Bambu dan Perlakuan Perendaman Strand terhadap Kualitas Oriented Strand Board

Abstract

Bamboo is a viable choice for particle board manufacturing due to its robust mechanical strength. This research aims to analyze the physical and mechanical properties of Oriented Strand Board (OSB) made from three types of bamboo: belangke bamboo (Gigantochloa pruriens), betung bamboo (Dendrocalamus asper), and black bamboo (Gigantochloa atroviolacea). The bamboo samples will be subjected to three different treatments: soaking in water for 24 hours, autoclaving at a temperature of 120ºC for 1 hour, and a control group. The Oriented Strand Board (OSB) was manufactured with precise dimensions of 20 cm x 20 cm x 1 cm (Length x Width x Thickness). It was assembled using H3M isocyanate adhesive and underwent a conditioning process for a duration of 14 days. The physical properties of Oriented Strand Board were tested and the following values were determined: density ranged from 0.60-0.73 g/cm3, water content ranged from 5.36-8.12%, water absorption ranged from 31.6-45.82%, thickness expansion ranged from 5.11-16.27%, MOE ranged from 27,992 – 73,249 kgf/cm2, MOR ranged from 314 – 600 kgf/cm2, and IB ranged from 2.80-4.76 kgf/cm2. The term "physical and mechanical properties testing" pertains to the standard JIS A 5908:2003 and CSA 0437.0:2011.
