An Investigatory Project on Cassava Starch Bioplastic as Alternative Commercial Plastic Bags

Vol.4, No.1

Abstract

An investigatory project on cassava starch bioplastic as an alternative to commercial plastic
bags will be used to reduce the rising problem of plastic waste that is destroying and polluting
the environment. Since cassava is a renewable source that contains a large amount of starch,
it is suitable for making bioplastic. Bioplastic comes from a renewable source like cassava that
can degrade within 45 days, unlike plastic made of petroleum, which could take 1000 years to
decompose.

The results of the study in terms of ingredients are both chemical engineers and
environmental engineers strongly agree. In terms of procedural processes, both chemical
engineers and environmental engineers strongly agree. In terms of durability, Chemical
engineers agreed, while the environmental engineers disagreed. In terms of suitability, both
chemical engineers and environmental engineers agreed. In terms of presentation, both
chemical engineers and environmental engineers agreed. It indicates that there is no
significant difference between the assessment of the two groups of respondents in terms of
ingredients, procedural process, durability, suitability, and presentation. The chemical
engineers obtained a 3.37 overall weighted mean, while the environmental engineers got a
2.99. With a variance of 0.056 in chemical engineers and 0.214 in environmental engineers.
The t-critical value is 2.306, and the t-computed is 1.635. Therefore, it accepts Ho.

There is no significant difference between the two groups of respondents on the level of
acceptability assessment of cassava starch as an alternative bioplastic in terms of ingredients,
procedural process, durability, suitability, and presentation.
