THE EFFECTIVENESS OF COGON GRASS (imperata cylindrica) AS CARDBOARD

To test Cogon grass if it is effective to use as a substitute commercially available carboard

by: Patrick Corpuz & Jerome Ong

ABSTRACT

  • The effectiveness of cogon grass (Imperata cylindrica) as substitute for cardboard food packaging was studied in this research project.
  • cogon grass will will be cut, boiled, strain, screened and dry to make a cardboard.
  • it was done with 3 treatments, treatment A, B, and C. and test the cardboard in terms of breaking strength and water retention.

ABSTRACT

AIM

THIS RESEARCH STUDY, THE EFFECTIVENESS OF COGON GRASS(IMPERATA CYLINDRICA) AS CARDBOARD, AIMS TO HAVE A SUSBTITUTE CARDBOARD TO REDUCE CUTTING TREES TO PRODUCE A PAPER. RESEARCHERS WANT TO STUDY IF THERE ARE OTHER MATERIALS LIKE COGON GRASS CAN BE A MAIN MATERIAL TO PRODUCE A CARDBOARD. IN THIS WAY, WE CAN SAVE TREES AND WE CAN SAVE WORLD BY USING OTHER RESOURCES.

AIM

METHODOLOGY

  • represents the used research method in the study, procedure in data gathering, sampling design and the statistical treatment of the data gathered from the survey.
  • The data was gathered through the results of the experiment. Then for the statistical treatment, weighted means of each variable were taken. The respective mean results of each variable were recorded and compared to each other using the T-Test. The comparisons were presented in graphical and tabular forms for efficient reading.

research design

The method of research used by the researchers is the experimental method. This method is very much viable in testing the effectiveness of cogon grass as cardboard. The researchers will have a more efficient way of gathering and analyzing data. It also removes biases and outside factors.

CONCLUSION

Cogon grass is not effective in terms of

  • breaking strength
  • water retention
  • customer appeal

The product has no significant differences with commercially available cardboard in terms of

  • breaking strength
  • water retention
  • customer appeal

CONCLUSION

recommendations

  • it is important to have a concrete constant variable in the variable in the experiment so the researchers would have something to compare to.
  • Time is essential when you are dealing with construction of materials such as paper, cardboard or even tiles, because it involves sunlight.
  • Thickness should be a factor in the experiment so upon doing the procedures one should consider the amount of grass added into the mixture and the amount to put layer by layer on the silkscreen so that the thickness, shall remain a constant variable.

statistical treatment data

Since the study is a quantitative research specifically experimental, it involves creation of new product or innovation of an existing product. The researchers used t-test to further compare the significant difference between.

statistical treatment data

results and discussions

RESULTS: BREAKING STRENGTH

The results for the determination of the level of effectiveness of Cogon grass was by the breaking strength test were illustrated in table 1. Table 1 shows that treatment B has the highest breaking strength at a mean of 453.33, while treatment C has the second in breaking strength with a mean of 303.3, and treatment A has the least breaking strength with a mean of 278. In terms of the strength of the paper, Treatment B has the best treatment compared with A, B, and C treatment. However, commercially available cardboards are still the best.

RESULTS: WATER RETENTION

RESULTS: WATER RETENTION

The results for the determination of the level of effectiveness of Cogon grass was by the water retention test were illustrated in table 2. Table 2 shows that the treatment A has the highest water retention with a mean of 0.31, while treatment C has the second to the highest water retention with a mean of 0.25, and treatment B has the least water retention it is again the best treatment. Thus, treatment B has the least water retention and it is the most water resistant.

RESULTS : T-TEST

RESULTS : T-TEST

shows the statistical presentation of the differences between the experimented cardboard and the commercially available cardboard. The commercially available cardboard served as the basis of acceptance of the Treatment B. If the absolute value of t-stat is lower that the t-critical, there is no significant difference. The t-stat on terms of the breaking strength test is 2.919986 and the t-critical is 4.302653, computed with alpha 0.05. The table shows that the t-stat is lower that the t-critical, accepting the null hypothesis, the data represents that there is no significant difference between treatment B and the commercially available cardboard. The t-stat on terms of the water retention test is 0.021944 and the t-critical is 0.103235, computed with alpha 0.05. The table shows that the t-stat is lower that the t-critical, accepting the null hypothesis, the data represents that there is no significant difference between treatment B and the commercially available cardboard.

SUMMARY

  • The data were statistically treated among the comparison of cogon grass ( Imperata cylindrica) with commercially available cardboard in terms of breaking strength and water retention using t-test..
  • The results for the determination of the level of effectiveness of cogon grass was by the breaking strength test were illustrated. Treatment B is the highest breaking strength at a mean of 453.33,
  • Treatment B has the best treatment compared with A, B, and C treatment. In water retention test shows that treatment A has the highest water retention with a mean of 0.25, and treatment B has the least water retention it is again the best treatment.

CONCLUSION

CONCLUSION 1

1.) Cogon grass is not effective in terms of

  • breaking strength

Cogon grass is not effective in terms of breaking strength in treatment A having the least mean of 278g.

  • water retention

Cogon grass is not effective in terms of water retention in treatment A, having the highest mean of 0.31

  • customer appeal

Cogon grass is not effective in terms of customer appeal in treatment A, having a very rough texture and a strong odor of dried leaves.

CONCLUSION 2

The product has no significant differences with commercially available cardboard in terms of

  • breaking strength

Cogon grass cardboard, treatment B has no significant difference with commercially available cardboard in terms of breaking strength having a lower t-stat of 2.919986 than that of the t-critical of 4.302653, thus accepting the null hypothesis.

  • water retention

Cogon grass cardboard, treatment B has no significant difference with commercially available cardboard in terms of water retention having a lower t-stat of 0.021944 than that of the t-critical of 0.103235, thus accepting the null hypothesis.

  • customer appeal

Cogon grass cardboard, treatment B has no significant difference with commercially available cardboard in terms of customer appeal, having attractive color and a little bit roughness of its texture.

RECOMMENDATIONS

  • it is important to have a concrete constant variable in the variable in the experiment so the researchers would have something to compare to.
  • Time is essential when you are dealing with construction of materials such as paper, cardboard or even tiles, because it involves sunlight.
  • The work is associated of what kind of weather there is, so one must make sure to do his work ahead of time.
  • Thickness should be a factor in the experiment so upon doing the procedures one should consider the amount of grass added into the mixture and the amount to put layer by layer on the silkscreen so that the thickness, shall remain a constant variable.
  • Lastly, the researchers must consider the availability of the materials that they will use in this experiment. More is better than less, because if there is something that you need to redo in this experiment, the researchers would have more extra materials to use especially that this experiment requires patience and creativity.
