        <dc:description>The deterioration of water quality due to industrial wastewater, particularly&#13;
from dyes such as methylene blue, has driven the need to develop effective and&#13;
environmentally friendly adsorbent materials. This study aims to isolate nanocellulose&#13;
from oil palm empty fruit bunch (OPEFB) waste, synthesize composite beads&#13;
based on nanocellulose, mesoporous silica, and sodium alginate, and investigate the&#13;
adsorption mechanism of methylene blue. Nanocellulose was obtained through a&#13;
series of processes including delignification, bleaching, TEMPO-mediated oxidation,&#13;
and ultrasonication, and subsequently synthesized into beads using an ionic&#13;
gelation method with CaCl₂. Characterization was carried out using FTIR, XRD,&#13;
SEM, TEM, and TGA, while adsorption experiments included variations in contact&#13;
time, adsorbent dosage, solution pH, and Isoterm analysis. The results showed that&#13;
nanocellulose was successfully isolated with an average diameter of 3,83 nm and&#13;
possessed active functional groups that support the adsorption process, while the&#13;
resulting composite beads exhibited a stable structure and porous morphology. The&#13;
contact time study indicated that adsorption occurred rapidly at the initial stage and&#13;
reached equilibrium at 180 minutes. Increasing the adsorbent dosage enhanced adsorption&#13;
efficiency due to the greater availability of active sites on the adsorbent&#13;
surface. Adsorption performance was influenced by operating conditions, with optimum&#13;
results at pH 7, and followed the Freundlich Isoterm model, indicating a&#13;
heterogeneous surface characteristic.Overall, nanocellulose-based composite beads&#13;
derived from OPEFB demonstrate significant potential as an effective and sustainable&#13;
adsorbent for dye wastewater treatment.</dc:description>
