In this research, the ability of papaya tree trunks as nanocellulose adsorbent for dyes removal was conducted. The synthesis of nanocellulose is carried out in several steps, including isolation of cellulose using the extraction method, immersion with a variety of alkaline bases, namely KOH, KOH+NH 3 , and KOH+Na 2 CO 3 and synthesis of nanocellulose by hydrolysis reaction. The adsorption process was carried out in batch method, by contacting the nanocellulose adsorbent with the dye, then filtered and observed the change in concentration using UV-Vis. Meanwhile, to observe the functional groups contained in the nanocellulose obtained from synthesis of papaya tree stems FTIR result was evaluated. The results showed that all cellulose-forming groups (CO, CH 2 , CH) were present in synthesis nanocellulose in accordance with those of the commercial. The synthesis results with variations in the alkaline base which the closest to commercial yield was the variation with the alkaline KOH base. In addition, determination of adsorption performance of ones is compared with performance of commercial nanocellulose.
