ABSTRACTThe study entitled THE PRODUCTION OF BIODEGRADABLE
PLASTIC USING VARYING KINDS OF PLANT STARCH was conductedby Camille C. Manansala and Arizza Mae C. Delos Reyes to produce and
compare biodegradable plastic using varying kinds of plant starch.
The researcher used the Experimental method. They
measured out 60 mL (4 tablespoons) of cold water and poured it into the
beaker or container where it was heated. They added 10 grams (about 1tablespoon) of starch then added water. Then they put 5 mL (1 teaspoon)
of acid (white vinegar) to the mixture. Then added 5 mL (1 teaspoon) of
vegetable liquid glycerin (vegetable oil) to the mixture, more glycerin will
make it softer and more flexible. They turned the burner low and
constantly stirred the mixture. When it started to thicken up, they turnedthe heat up to medium and stirred even more. When it started to boil, they
kept it boiling for 5 minutes. They got a very clear and sticky substance.
After getting the gooey substance, they poured it into a mold with
aluminum foil to keep it from sticking into the mold. They let it dry under
the sun.

Eleven respondents tested each treatments in terms of smell and
appearance and graded from 1-4.
They tested the biodegradability of each treatment. The
researchers provided a plot with soil. They buried the plastic in it then
recorded the changes every week.
They tested the durability of each treatment by putting
25 grams of rice on the biodegradable plastic and lifted it. Another 25
grams was placed on each treatment and lifted again. This procedure
was repeated until the researchers determined the best plastic in terms
of durability.The researchers used the Analysis of Variance and the
T-Test to determine the significant difference among the different kinds of
starch as biodegradable plastic.
There is a significant difference among the varying kinds
of plant starch in terms of: Potato starch is the best in terms ofbiodegradability with the mean of 0.002; Cassava starch is best in terms
of Durability with a capacity of 2.25 kg and; Potato starch is best in terms
of appearance having the computed T value of -1.083 and -0.142.
There is no significant difference among the smell of the
varying kinds of plant starch with the computed F value of 0.504.

STATEMENTOFTHEPROBLEM
Generally, the study aims to produce and compare biodegradable plastic
using varying kinds of plant starch.
Specifically, it also aims to answer the following questions:
What kind of starch is best in terms of:
Biodegradability,
Durability,
Smell and Appearance?

SCOPEANDLIMITATIONS
The study aims to produce biodegradable plastic using varying
kinds of plant starch specifically, Potato starch, Cassava Starch, and Corn
Starch.
The study was conducted in the Delos Reyes residence specifically at
their kitchen and will cover three months or twelve weeks.
The study not related was not be discussed such as other
biodegradable plastic, commercial biodegradable plastic, other starches
and figure of the plastic.
The study mainly focuses in the comparison of the varying kinds
of plant starch as an alternative ingredient in the production of
biodegradable plastic.

At the left box of the framework were the independent variables thatwere used in the study. Each starch undergo the procedure found in the middle
box wherein the researchers Mixed 6 table spoon of starch, 3 tablespoon of
vinegar and 3 tablespoon of oil, applied heat and put in a molder to form the
biodegradable plastic found at the last box.

CONCLUSIONS
Based on the results, the following conclusions were derived:
1. There is a significant difference among the varying kinds of plant
starch in terms of:
a. Potato starch is the best in terms of biodegradability.b. Cassava starch is best in terms of Durability.
c. Potato starch is best in terms of appearance.
2. There is no significant difference among the smell of the varying
kinds of plant starch

RECOMMENDATIONS
From the conclusions, the following recommendations were given:
The researchers recommend that use a machine in making the
biodegradable plastic.
The researchers recommend add more starch in the variables like rice
starch and the like.
