Sifat Fisik dan Keawetan Kayu Cemara Gunung (Casuarina junghuniana) di Pegunungan Bromo Kabupaten Probolinggo

Physical Characteristics and Durability of Cemara Gunung Wood (Casuarina junghuniana) in
the Mt. Bromo Probolinggo. The purpose of this study is to find out the physical characteristics of
Cemara Gunung wood and to know the durability of Cemara Gunung wood toward termite. The using
methods were knowing the water content, density, and the development of wood thickness.
Meanwhile, the selecting of wood durability test without the selecting of using soil termites
(Macrotermes gilvus) against the three wood samples by using (SNI) 01-7207-2014 regarding the
durability of wood test towards wood-destroying organisms. The deriving results showed that the
moisture content of the sapwood portion was larger than the heartwood, based upon the highest
density test on the heartwood, which was 1.24 g/cm3, the density of sapwood I and sapwood II was
almost equal to 0.81-0, 82g/cm3. The greater the density value, the stronger the wood. The thick
development is directly proportional to density, the thick development value of the two treatments is
not too high due to hard Cemara Gunung wood. Based on the termite test showed the average weight
reduction in the wood core test sample <3.52% (very resistant) class I. For testing sapwood, I and
sapwood II (preservative) were not much different because it was included in the resistant class (3, 52-
7,50) (class II). From the three trials of termite in bottles, the 15-day test (the bottle I) was the most
effective followed by bottle II and bottle III.
