Abstrak

Penelitian ini mengkaji pengaruh impregnasi dengan tembaga sulfat (CuSO₄) terhadap sifat fisik dan mekanik kayu sengon (Falcataria moluccana) dan kayu kelapa (Cocos nucifera) untuk aplikasi bangunan ramah lingkungan. Sampel kayu berusia 7 tahun yang berasal dari Samarinda, Kalimantan Timur, diolah menggunakan metode impregnasi vakum-tekan. Sifat fisik dievaluasi melalui persen kenaikan berat (WPG) dan kerapatan, sedangkan sifat mekanik dinilai berdasarkan modulus elastisitas (MOE) dan modulus patah (MOR). Impregnasi CuSO₄ secara signifikan meningkatkan WPG dan kerapatan pada kedua jenis kayu tersebut, dengan kayu kelapa menunjukkan nilai persen kenaikan berat yang lebih tinggi (21,84%) dibandingkan kayu sengon (14,47%) karena strukturnya yang lebih berpori. MOE menurun pada kedua jenis kayu setelah perlakuan, dengan penurunan yang lebih besar pada kayu sengon karena kerapatannya yang lebih rendah. Untuk MOR, kayu sengon menunjukkan penurunan yang sedikit, sedangkan kayu kelapa menunjukkan peningkatan dari 587,42 kg/cm² menjadi 663,96 kg/cm², yang dikaitkan dengan interaksi antara larutan impregnasi dan struktur seratnya yang lebih padat. Impregnasi CuSO₄ lebih efektif dalam meningkatkan kekuatan lentur kayu kelapa, meskipun penurunan kekakuan pada kedua jenis kayu tersebut perlu dipertimbangkan untuk aplikasi bahan bangunan berkelanjutan.
