Optimization Preservation Of Betung Bamboo (Dendrocalamus Asper) With Hot Soaking Method Using ketapang leaves (Terminalia catappa L)

This study aims to determine the optimization of the concentration of ketapang leaves and the time of immersion in absorption, retention, and weight loss of Betung bamboo (Dendrocalamus asper). The preservation method carried out is the cold immersion method using the central composite design. The results showed that the optimization for the retention, absorption, and loss of weight of Betung bamboo was at a concentration of 5-15 (%) and soaking time 40-60(hours). The result is retention weight loss 2 % while the MOR value is 1500 kg/m3. This weight loss, the value indicates that preservation using preservatives provides a very resistant value (SNI 79206) to the attack of powder beetles. It also shows that preserving with Ketapang leaves does not cause a change in mechanical properties
