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.
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.
Cogon grass is not effective in terms of
The product has no significant differences with commercially available cardboard in terms of
It includes the materials, flow diagram procedure, and STD
CUT IT INTO 0.5 INCH STRIP
COGON GRASS WAS LEFT AND DRY
STRAIN IT AFTER BOILING
BOIL IT INTO 2-3 HOURS IN A MEDIUM HEAT
SCREENED IT, AND LET IT DRY
AFTER STRAINING, BLEND IT OR PRESS IT TO REMOVE THE EXCESS WATER
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.
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.
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.
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.
CONCLUSION 1
The product has no significant differences with commercially available cardboard in terms of
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.
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.
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.
