Pemanfaatan Selulosa Ampas Industri Pati Sagu Sebagai Filler Dalam Pembuatan Bioplastik Berbasis Pati Sagu

ABSTRACT
Bioplastics are eco-friendly alternatives to petrochemical plastics, capable
of degrading naturally. Starch-based bioplastics, such as those from sago are
renewable but limited by brittleness and moisture sensitivity. To enhance their
performance, cellulose fillers are often incorporated. Sago pulp, a lignocelluloserich
byproduct of sago starch processing, offers promising potential as a sustainable
filler material. This study aims to determine the optimal percentage of sago pulp
cellulose addition for enhancing the physical and mechanical properties of sago
starch-based bioplastics. This experimental study was conducted using a
completely randomized design (CRD) nonfactorial with four treatments and four
replications, resulting in 16 experimental units. The treatments involved varying
concentrations of sago pulp cellulose in the bioplastic formulation: P1 (9% w/w),
P2 (12% w/w), P3 (15% w/w), and P4 (18% w/w). Data were statistically analyzed
using analysis of variance (ANOVA) with IBM SPSS software version 25. When
the calculated F-value was greater than or equal to the critical F-value, Duncan’s
Multiple Range Test (DMRT) at a 5% significance level was performed for further
analysis. The ANOVA results indicated that variations in sago pulp cellulose
concentration had a significant effect (p < 0.05) on water absorption, water vapor
transmission rate, tensile strength, elongation, and biodegradability of the
bioplastics. The best-performing bioplastic formulation was obtained with
treatment P3 (15% w/w), yielding a water absorption of 32.74%, water vapor
transmission rate of 16.24 g/m².hour, tensile strength of 17.71 MPa, elongation of
10.95%, and biodegradability of 48.51% after 10 days of soil burial.
