Permasalahan utama dalam industri pengolahan kayu di Indonesia adalah keterbatasan bahan baku kayu berkualitas tinggi akibat eksploitasi berlebih. Teknologi papan laminasi menjadi solusi inovatif yang memungkinkan pemanfaatan kayu lokal berdiameter kecil dan berkualitas menengah. Penelitian ini bertujuan untuk menganalisis dan membandingkan sifat fisika papan laminasi dari kayu bajur dan kombinasi kayu nangka-mahoni, meliputi parameter kerapatan, kadar air, pengembangan tebal, dan penyusutan tebal. Metode yang digunakan adalah eksperimen dengan Rancangan Acak Lengkap (RAL) non-faktorial dengan dua perlakuan dan tiga ulangan, mengacu pada standar JAS 234-2003. Hasil menunjukkan bahwa papan laminasi nangka-mahoni memiliki kerapatan lebih tinggi (0,579 g/cm³) dan kadar air lebih rendah (12,316%) dibanding bajur (0,506 g/cm³; 13,600%). Namun, papan bajur menunjukkan resistensi yang lebih baik terhadap pengembangan tebal dan lebih rentan terhadap penyusutan. Kedua jenis papan memenuhi standar kualitas yang berlaku dan menunjukkan potensi sebagai material alternatif dalam industri furnitur dan konstruksi. Penelitian ini memperkaya data empiris tentang performa kayu lokal dalam aplikasi laminasi dan mendukung diversifikasi bahan baku industri berbasis kayu.
Comparative Analysis of Physical Properties of Laminated Boards from Bajur Wood and Jackfruit Mahogany Combination
Abstract
The Indonesian wood industry faces a raw material shortage due to excessive exploitation of high-quality, large-diameter timber. Laminated wood boards offer an innovative solution by utilizing small-diameter and medium-quality local wood. This study aims to analyze and compare the physical properties of laminated boards made from bajur wood and a jackfruit-mahogany combination, focusing on density, moisture content, thickness swelling, and thickness shrinkage. The experiment applied a non-factorial Completely Randomized Design (CRD) with two treatments and three replications, following JAS 234-2003 standards. Results show that jackfruit-mahogany boards had higher density (0.579 g/cm³) and lower moisture content (12.316%) than bajur boards (0.506 g/cm³; 13.600%). However, bajur boards demonstrated better resistance to thickness swelling and were more prone to shrinkage. Both types of laminated boards met the required quality standards and are promising as alternative materials in furniture and construction industries. This research contributes to empirical data on local wood performance in laminated applications and supports diversification of wood-based raw materials.
