Karaktersitik Anatomi, Fisis, dan Mekanis Kayu Waru Gunung (Hibiscus macrophyllus Roxb.)

Abstract

Pohon waru (Hibiscus macrophyllus Roxb.) merupakan tanaman dari keluarga Malvaceae. Kayu waru banyak dipergunakan untuk konstruksi atau industri meuble. Tujuan penelitian untuk menganalisis karakteristik anatomi, fisis dan mekanis dari kayu Waru Gunung (Hibiscus macrophyllus Roxb.). Pengujian sifat anatomi meliputi ciri makroskopis dan dimensi serat. Sedangkan sifat fisis meliputi kadar air, kerapatan dan berat jenis serta penyusutan. MOE (Modulus of Elasticity), MOR (Modulus of Rupture) dan kekerasan arah radial/tangensial diuji pula dalam penelitian ini. Hasil penelitian menunjukkan serat kayu waru gunung diklasifikasikan menjadi kualitas serat kelas II. Berdasarkan sifat fisis dan mekanisnya kayu waru termasuk ke dalam kelas kuat III – V.

Hibiscus macrophyllus Roxb., commonly known as Kayu Waru, belongs to the family Malvaceae. Waru wood is commonly utilized in construction and the furniture industry. The aim of this research is to analyse the anatomical, physical, and mechanical properties of Kayu Waru Gunung. Anatomical characteristics examined macroscopic and fibre dimensions. Physical properties conducted on moisture content, density, specific gravity and shrinkage. Mechanical properties evaluated MOE (Modulus of Elasticity), MOR (Modulus of Rupture), and hardness in radial and tangential directions. Research resulted Waru Gunung had fiber quality class II. Based on its physical and mechanical properties, the wood is categorized under strength classes III–V.
