Daftar Isi:
- Natural durability of 57 wood species originated from several regions in Indonesia was investigated outdoor under coverage. Initially, wood specimens were prepared from each species with dimension of 20 cm (length), 10 cm (width) and 2.5 cm (thickness). Specimens were placed on top of the bricks to avoid direct contact with soil, arranged randomly, and covered with crated-plastic sheets which served as protecting shades. Such experiment was conducted in research forest, Cikampek, West Java. Observation was conducted one year afterwards included evaluating the percentage of deteriorated wood specimens due to wood-destroying organisms. Results showed that after a year, 57 wood species could be categorized into five classes. Further scrutiny on each class revealed that four wood species belonged to class I (very durable); 16 wood species were class II (durable), 15 wood species class III (fairly durable), three wood species class IV (non-durable), and 19 wood species were classified as class V (perishable).
- Lima puluh tujuh jenis kayu dari berbagai daerah di Indonesia diuji keawetan alaminya di luar ruangan di bawah naungan. Contoh uji berukuran 20 cm (panjang); 10 cm (lebar); 2,5 cm (tebal) dipersiapkan dari masing-masing jenis. Contoh uji diletakkan di atas batako agar tidak berhubungan langsung dengan tanah, selanjutnya disusun secara acak, dan ditutup plastik kasa sebagai naungan. Pengujian keawetan alami tersebut dilaksanakan di hutan penelitian Cikampek, Jawa Barat. Pengamatan dilakukan setelah satu tahun pengujian dengan cara menilai persentase kerusakan contoh uji yang disebabkan oleh organisme perusak kayu. Hasil penelitian menunjukkan setelah satu tahun pengujian, 57 jenis kayu dapat dikelompokkan ke dalam lima kelas keawetan. Hasil pencermatan menunjukkan empat jenis kayu termasuk kelas I (sangat awet), 16 jenis kayu kelas II (awet), 15 jenis kayu kelas III (sedang), tiga jenis kayu kelas IV (tidak awet), dan 19 jenis kayu kelas V (sangat tidak awet).
