The study measures the contact angle and evaluates the suitability of these wood species for plywood production. Logs from a community forest were processed to convert into thin slices of veneer using the rotary cutting method at a plywood plant. Subsequently, the study analyzed the wetting behavior of the veneer samples resulting from a rotary process on tangential surfaces without smoothing treatment with distilled water. The veneer was then made into plywood using an adhesive nanofiller of phenol formaldehyde mixed with wood bark powder. Ball milling produced nanofillers from the bark of jabon, gmelina, and surian with nanoscale particle diameter size (10–1000 nm). The bonding strength of the plywood was evaluated under cyclic and dry test conditions according to Japanese Standards. The study shows that P. falcataria, H. brasiliensis, and A. cadamba have a smaller contact angle than T. sinensis, G. arborea, and M. glauca. Thus, the higher wettability of P. falcataria, H. brasiliensis, and A. cadamba results in a better adhesive spread and more intimate contact between the wood surface and the adhesive. However, the study found higher bonding strength values for H. brasiliensis and T. sinensis plywood using jabon nanofiller, followed by T. sinensis plywood using surian nanofiller and H. brasiliensis plywood using gmelina nanofiller.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Contact angle measurement,Gmelina,Jabon,Surian,Wettability[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to thank the Directorate of Research and Community Services, Ministry of Research, Technology and Higher Education of the Republic of Indonesia for their financial support under the research scheme of Postdoctoral Research for the Fiscal Year 2018.
