JENIS-JENIS POHON KAYU DI KEBUN RAYA CIBODAS
ABSTRACT: Botanical Garden
including information on their physical
and mechanical properties,
natural durability, distribution, prospect and other supporting
data; (2) to analyze the lesser-known wood species that could be used for construction materials and then recommend
them to be developed through Industrials Plantation Forest. The steps of the
study were first collection of data on timber species from herbarium catalogue;
second collection of data on the properties of wood from various sources; third,
observation of stem morphology in the field. The result of the catalogue study
showed that there were 291 timber tree species grown in Cibodas Botanical
Garden which were comprised of 14 major commercial timbers, 74 minor commercial
timbers, and 142 lesser known timbers. These timber species were also
distributed in other parts of Indonesia. Observation in the field then
generated 49 lesser-known wood species that could be used for construction
materials based on their stem form and branch height. From the reference and
catalogue study, it was found that there were 14 wood species belongs to
strength class I to III with natural durability ranges from very durable to
moderate. These woods were then evaluated based on their morphological features
and prospects. Finally, it was found that only ten wood species that were
suitable to be used for construction materials, i.e. Acmena acuminatissima
(Blume.) Merr. & Perry (Kelat); Adenanthera microsperma Teijsm. & Binn.
(Saga); Baccaurea parviflora (Muell. Arg.) (Setambun); Casuarina junghuhniana
Miq. (Cemara Gunung); Garcinia parvifolia and G. beccari (Manggis Hutan);
Gymnostoma sumatranum (Joogb. ex de Vriese) L.A.S. Johnson (Cemara Sumatra);
Mimusops elengi L. (Tanjung); Neonauclea lanceolata and N. obtusa (Ki Anggrit).
However, the result of this study needs to be supported by further study on
their wood properties since the present data were mostly qualitatives. Further
research concerning their silviculture, growth rate, and susceptibility to the
diseases were also needed to be done.
