abstract: The porang-CMC starch formulation and glycerol concentration play an important
role in the mechanical properties of the resulting biodegradable film. This
research aims to determine the porang-CMC starch formulation with glycerol
concentration on tensile strength, thickness, percent elongation, and water vapor
transmission rate of biodegradable films, as well as determine the interaction of
porang-CMC starch formulation with glycerol concentration in producing tensile
strength, thickness, percent elongation, and the best water vapor transmission rate
of biodegradable film. This research consists of the stages of the process of
making porang starch and making biodegradable film. The research was
structured in a Complete Randomized Block Design (CRBD) with two factors and
three replications. The first factor is the porang starch and CMC formulation with
3 levels, namely 25%:75% (F1); 50%:50% (F2); 75%:25% (F3) and the second
factor is the glycerol concentration, namely 1% (G1), 2% (G2), 3% (G3). The data
obtained were analyzed for similarity of variance using the Bartlett test and
additional data was tested using the Tuckey test, analysis of variance was
analyzed to determine the effect between treatments followed by the Least
Significant Difference (LSD) test at the 5% level. The results show that the
interaction between the formulation factors of 25% porang starch and 75% CMC
with a glycerol concentration of 1% produces the best porang starch-based
biodegradable film by producing tensile strength values of 32.44 MPa, thickness
of 0.25 mm, percent elongation of 36.50%; water vapor transmission rate 14.486
g/m2/24 hours, and biodegradability for 14 days.
