THE RELATIONSHIP OF BASIC DENSITY WITH 1-5 AGE GROUP Schizostachyum brachycladum.

This is the study of physical properties of bamboo from the species Schizostachyttm brachycladum. The bamboo samples were taken in Dabong forest. Bamboo culm of aged 1, 2, 3 and 4 years were used in this study. For the physical properties, the tests were carried out on the four factors of moisture content, basic density, swelling, shrinkage. The internodes from 2 until 28 were used. Basic density year 1 is 0.51, year 2 is 0.61, year 3 is 0.5, year 4 is 0.5 and year 5 is 0.62. For the moisture content, aged 1 bamboo is 59.44 aged 2 is 52.44 , aged 3 is 48.94 , aged 4 is 35.83 is and lastly aged 5 is 30.34. For the swelling, aged 1 of bamboo have the value of 51.52, aged 2 is 48.26 , aged 3 is 32.5, aged 4 is 35.69 and lastly is aged 5 that is 32.05.Lastly, the test for shrinkage. Year 1 bamboo is 28.9, year 2 is 31.07, year 3 is 33.03, year 4 is 40.00 and year 5 is 43.62. .
