Teak wood is a type of hardwood that is abundant in Indonesia. Generally, this wood is widely used for housing structures and furniture. But from these uses, the resulting waste has not been widely used. One of the uses of this waste is to isolate of the cellulose contained in teak wood, thus giving it a high value later. The teak wood powder was isolated through a base delignification process followed by hydrothermal to obtain useful quality cellulose. This study aims to determine the characteristics of cellulose resulting from the combination of these processes. In the base delignification process, wood powder is processed using 0.2 M NaOH at 40°C for 30 minutes. In order for the process to run optimally, this process is assisted by ultrasound. Then proceed with the hydrothermal process at a pressure of 100 bar and a temperature of 200°C at various times. From the Chesson analysis, it can be seen that the composition of lignin and hemicellulose was decreased. Moreover, from the scanning electron microscopy analysis, it can be seen that the resulting cellulose is in the form of rods with the highest crystallinity degree of 79.33%.
