Abstract

English

Binuang bini (Octomeles sumatrana) and binuang laki (Duabanga moluccana) are fast growing species that have the potential to be developed as engineered wood products. However, previous studies have shown that both wood species have high contact angle values due to the extractive content and the high acidity. Therefore, this study aimed to examine the effect of hot water extraction (HWE) pretreatment to eliminate these limiting factors. The results proved that HWE pretreatment statistically significantly decreased the contact angle of binuang bini wood but not for binuang laki wood. HWE pretreatment resulted in a decrease in the levels of hot water-soluble extractive content and degradation of other wood chemical components. The different effectiveness of HWE pretreatment on binuang bini and binuang laki wood on improving the contact angle is influenced by differences in the quantity and quality of extractive substances as well as differences in the anatomical structure characteristics of these species.

Binuang bini (Octomeles sumatrana) dan binuang laki (Duabanga moluccana) merupakan jenis cepat tumbuh dan tumbuhan pioneer yang berpotensi dikembangkan sebagai engineered wood products. Akan tetapi, penelitian sebelumnya membuktikan bahwa kedua jenis kayu tersebut memiliki nilai sudut kontak yang tinggi dan diduga disebabkan karena kandungan zat ekstraktif serta Tingkat keasaman kayu yang tinggi. Oleh karena itu, penelitian ini bertujuan untuk mengkaji pengaruh pemberian perlakuan pendahuluan hot water extraction (HWE) untuk mengeliminasi faktor penghalang tersebut. Hasil penelitian membuktikan bahwa secara statistik perlakuan pendahuluan HWE signifikan menurunkan sudut kontak kayu binuang bini tetapi tidak untuk kayu binuang laki. Perlakuan pendahuluan HWE berdampak pada penurunan kadar zat ekstraktif larut air panas dan degradasi komponen kimia kayu lainnya. Efektivitas perlakuan pendahuluan HWE yang berbeda pada kayu binuang bini dan binuang laki terhadap penurunan sudut kontak kayu dipengaruhi oleh perbedaan kuantitas dan kualitas zat ekstraktif serta perbedaan karakteristik struktur anatomi kedua jenis kayu tersebut.
