Pengaruh Gliserin Dan Asam Asetat Pada Pembuatan Bioplastik Dari Tepung Tapioka Dan Tepung Maizena
ABSTRACT
Bioplastics are destructive plastics which break down by the environment,
humidity and microorganism activity. These bioplastics can be used just like
conventional plaques. Bioplastics include natural polymers made from plant and
animal materials. Tapioca flour is pure starch obtained from the extraction of
cassava milling and continues to amylose and amylopectin. Maize flour is flour
obtained by grinding clean and good corn kernels through the process of
obtaining skin, endosperms, institutions and the tip of the hat. This research helps
make bioplastics using tapioca flour as an adhesive and cornstarch as an efficient
thickener. The use of tapioca flour and cornstarch in producing bioplastics in this
study was carried out using the blending method. Variations in the amount of
acetic acid were 2 ml, 4 ml and 6 ml, variations in the amount of glycerin were 2
ml, 4 ml and 6 ml and tapioca flour and cornstarch were 6 gr at 700C. Bioplastics
are made by mixing 6 gr tapioca flour and 6 gr cornstarch, 50 ml distilled water
and heated to a temperature of 700C. The tests carried out are testing tensile
strength, thickness, resistance and biodegradable bioplastics. The product
produced consists of 9 variants of bioplastics. Bioplastic test results announced by
the fourth bioplastic (2.649 MPa), the best thickness possessed by the ninth
bioplastic (0.12 mm), the best resistance needed by the eighth bioplastic (46.15%)
and the fastest or best degradation time by bioplastics three and ninth (6 days).
The effect of using glycerin is very dominant in the test results but not for the use
of acetic acid.
