【 摘 要 】

Bogor Botanical Garden has ± 14,000 living plant collections including shrubs, herbs, climber and trees. Tree collections exhibit different characteristics, larger dimensional shapes and can reach old ages. However, trees collections possess some flaws that could result in materials harm and other losses. The aim of this research was to define health condition of Agathis borneensis trees, as a base of determining treatment in Bogor Botanical Gardens. The method used was a combination of visual and sound waves assessment using arborsonic. Targeted trees were selected based on accessibility, tree diameter and age, and pest attack. Each tree was assessed with high risk by visual assessment and assessed using arborsonic on main stem. The height level of measurement point was based on sound, which was produced by rubber hammer tapping. This study concluded that there were 32 Agathis borneensis trees observed, where 4 trees were chosen as first priorities due to their decay level of above 60%, whereas the other 11 trees turned as the second priorities (30-60% decay level) and the last 17 trees became the third priorities (
