Abstract

This research is aimed to determine physical and mechanical properties of Ebony wood as a construction material. The physical and mechanical properties test is conducted based on ASTM D 143-94 code. The mean value of moisture content and specific gravity of Ebony wood is obtained 12,90% and 0,92 gr.cm-3 respectively. Meanwhile MOE, bending strength, compressive strength parallel to grain, shear strength, and tensile strength parallel to grain are 180.425,87 kg.cm-2; 1656,22 kg.cm-2; 861,55 kg.cm-2; 119,61 kg.cm-2; dan 2.319,03 kg.cm-2 respectively. Based on the test results, it can be concluded that Ebony wood is classified to Strength Class I due to PKKI 1961, so it can be recommended for use in heavy construction such as bridge and building structures

 

Penelitian ini bertujuan menentukan sifat fisis dan mekanis kayu  Ebony sebagai material  konstruksi. Pengujian sifat fisis dan mekanis dilakukan berdasarkan standar ASTM D 143-94.  -3Nilai kadar air rata-rata kayu Ebony diperoleh sebesar 12,90% dan berat jenis 0,92 gr.cm .  Sementara nilai rata-rata MOE, kuat lentur, kuat tekan sejajar serat, kuat geser, dan kuat tarik  -2 -2 -2sejajar serat berturut-turut adalah 180.425,87 kg.cm ; 1656,22 kg.cm ; 861,55 kg.cm ;  -2 -2119,61 kg.cm ; dan 2.319,03 kg.cm . Berdasarkan hasil penelitian dapat disimpulkan bahwa  kayu Ebony tergolong kelas kuat I menurut PKKI 1961, sehingga dapat direkomendasikan  untuk digunakan pada konstruksi-konstruksi berat seperti jembatan dan struktur bangunan.
