Abstract

JENDRO ZALUKHU Wood acetylation of Nephelium lappaceum, Artocarpus integer, and Baccaurea montleyana woods. Guided by LUTHFI HAKIM and RUDI HARTONO. Termites are wood destroying organisms that cause harm and considerable damage to buildings in Indonesia. Therefore, there should be methods of termite attack on buildings. Method of chemical modification of wood used in this study is acetylation using acetic acid solution is applied to the wood of fruit (Nephelium lappaceum, Artocarpus integer, and Baccaurea montleyana woods). The purpose of this study was to test the dimensional stability, and retention test measures the resistance of wood against termite attack on Nephelium lappaceum, Artocarpus integer, and Baccaurea montleyana woods after acetylation. The method is carried out three types of wood soaked in each concentration of acetic acid solution (control, 10%, 15%, 20% and 25%). The results showed that the acetylation of wood to improve dimensional stability (ASE). In addition, the process also increases the acetylation of wood resistance to termite attack. This is shown by the retention of preservative that occurs in wood diasetilasi. Acetylation with acetic acid solution of 25% has the highest retention value, and the weight loss due to termite attack the lowest. This means, the process of acetylation can increase the resistance of wood against termite attack.
