Keawetan Alami Dan Beberapa Sifat Fisis-Mekanis Empat Jenis Kayu Asal Parungpanjang, Kabupaten Bogor

Abstract

The limited availability of natural forest timber in the market has resulted in an increased demand for timber from plantations, including from community forests and gardens. To ensure the quality of the products to be produced, characteristics of these timbers need to be studied comprehensively. This research aims to study the natural durability and some physical-mechanical properties of wood from plantations, especially from community forests and gardens around Parungpanjang, Bogor. The wood species studied consist of suren, mahogany, sungkai and meranti. Natural durability of wood is evaluated based on weight loss and its resistance after being buried for 12 weeks at the Arboretum of FAHUTAN-IPB (field test), physical properties were measured gravimetrically; while mechanical properties are tested using UTM. The results show that compared to similar species from natural forests, the studied sungkai and mahogany woods are less durable while suren is more durable; on the other hand, the natural durability of meranti is not different. Density and specific gravity as well as the MOE, MOR, tensile strength parallel to the grain (σtk//) and hardness of all wood studied are lower; except for BJ and hardness in suren as well as σtk// in sungkai where they are higher compared to similar properties in natural forest wood species.
