Abstract

Woods that were placed outdoors were exposed to UV-induced photodegradation processes which damaged the lignin bonds in the wood resulting in the more susceptible woods against abrasion and weathering. This circumstance led to more finishing processes by applying paint to the wood surface carried out by industries and at the home level. Some finishing materials not only contribute to increasing the aesthetics of the wood surface but also increased the wood's resistance against harmful microorganisms. On the other hand, the resistance against pests did not increase as high as the resistance against outdoor weathering. In this study, pine woods and teak woods collected from the community forest were soaked in cold borax solution as a preservative agent before applying the paint to the wood surface. The treatments applied to the samples in this study were untreated control samples, preservative-treated samples, finishing-treated samples, and both preservative and finishing-treated samples. The results of this study showed that both teak and pine wood with preservative and finishing treatment were resistant to microbial damage (0% damage) after left 8 weeks of exposure in the outdoor area. However, there is a need to conduct further research with longer exposure time (1-2 years) to get more significant result differences between each treatment.

Abstract

Kenanga and sengon wood are known for their inferior properties, necessitating effort to enhance their quality. In Wood Industry, thermal modification was used to enhance wood properties especially dimensional stability. The objective of this research was to evaluated the effect of wood species and thermal modification on physical and mechanical properties of wood. The wood modified by steam treatment at temperature of 1260C at pressure of 0.14 MPa for 1 hour. The physical properties tested included density, moisture content, volumetric swelling, and anti-swelling efficiency. The mechanical properties tested were the modulus of elasticity and modulus of rupture. The mechanical properties of the wood were tested according to ASTM D 143-05 (1996), and all parameters were compared between the thermal-modified wood and the control. The results showed that the density and moisture content parameters were only influenced by wood species while thermal modification and interaction of wood species and thermal modification did not affect density and moisture parameters. Furthermore, heat modification significantly improved the dimensional stability of the wood, as evidenced by a decrease in volumetric swelling and anti-swelling efficiency value higher than 40%. Additionally, heat modification slightly enhanced the mechanical properties of kenanga and sengon wood as seen from the increased values of modulus of elasticity and modulus of rupture values.

Abstract

Kompetensi dan efisiensi penggunaan kayu menjadi penting untuk diperhatikan. Hal ini berkaitan dengan mulai terbatasnya jumlah pasokan kayu berkualitas dari hutan alam. Hutan rakyat merupakan alternatif pemasok kayu yang memiliki potensi cukup besar untuk memenuhi kebutuhan kayu baik skala UMKM lokal maupun industri nasional. Penelitian terkait karakteristik kayu pada hutan rakyat terus dikembangkan untuk mengetahui karakterstik kayu dalam mengoptimalkan nilai pemanfaatannya. Salah satu jenis kayu berpotensi tinggi dalam hutan rakyat adalah kayu dari jenis pohon buah-buahan, salah satunya kayu durian. Maka dari itu, penelitian ini bertujuan untuk mengkaji struktur anatomi dan sifat fisis kayu durian sebagai acuan dalam pemanfaatan kayunya secara optimal. Sifat fisis kayu durian menunjukkan bahwa kayu durian tergolong kelas kuat III dengan nilai berat jenis 0.48 dan nilai TJS 33.81 %. Struktur makroskopis kayu durian menunjukkan bahwa kayu durian memiliki pori berupa tata baur berbentuk lonjong berdiameter 143.78ยต, soliter dan bergabung dengan frekuensi 3 pori per mm2. Kualitas serat kayu durian terlihat dari nilai turunan dimensi serat (bilangan muhlstep, runkle ratio, daya tenun, koefesien kekakuan, nilai kelenturan) yang tergolong kelas II (kualitas sedang sebagai bahan baku pulp). Berdasarkan karakteristik anatomi dan sifat fisis dalam peneiltian ini, kayu durian berpotensi dimanfaatkan sebagai bahan produk laminasi maupun kayu pertukangan dalam konstruksi ringan
