( 4th Place REGIONAL DepEd-Intel Science Fair, S.Y. 2009-2010)
Researcher: Mark Lorenz Valdez
Research Adviser: Ma. Regaele E. Aranza
Research Plan
A. Problem:
The study will investigate if talahib (Saccharum spontaneum) can be used an effective main component of biodegradable plastic.
Specifically, it seeks to answer the the question:
Is there is a significant difference between biodegradable plastic from talahib and commercial plastic in terms of:
1. Tensile strength
2. Flammabilty
3. Reaction to acids and bases
4. Biodegradabilty
B. Hypotheses
Ha1: Talahib can be an effective main component of biodegradable plastic.
Ha2: There is a significant difference between the biodegradable plastic from talahib and the commercial plastic.
Ho1: Talahib can not be an effective main component of biodegradable plastic.
Ho2: There is no significant difference between the biodegradable plastic from talahib and the commercial plastic.
C. Description of Methods:
Ø Procedure
Talahib leaf sheaths will be collected from grasslands and will be sun-dried for twenty-four (24) hours. After cutting them into very small pieces, they will then be combined with different chemicals such as polyvinyl alcohol, sodium hydroxide in aqueous solution, glue, and glycerol to produce biodegradable plastics. Three samples of plastics will be made with different amounts of talahib pulp, as shown in the table below.
| Sample | Talahib Pulp (g) | PVA (g) | Glycerol (mL) | Glue (mL) | Distilled Water |
| A | 10 | 10 | 5 | 5 | 100 |
| B | 20 | 10 | 5 | 5 | 100 |
| C | 30 | 10 | 5 | 5 | 100 |
Ø Data Analysis
After the different samples are molded and cut into sheets, they will undergo laboratory testing which will include physical and chemical tests. The following will be tested to see if talahib can be an effective main component of biodegradable plastic: tensile strength test, flammability test, reaction to acid and base test, and biodegradability test. The results will be subjected to t-test method of analysis to see if there will be significant differences between the experimental plastic and the commercial one in terms of the given parameters.

so what's the result? please i need the results for my investigatory project in biology.
ReplyDeletenice idea for an investigatory project. but your results are quite insufficient and therefore,you haven't proven anything in your results. well ciao. have a good life. :)
ReplyDeleteYes, the results are not actually included here, as well as the conclusion. As you can see here, it was only the RESEARCH PLAN that was posted here. If you are interested with the entire study write up you may contact the researcher. (name stated above) :-) Thanks for your comments. God bless!
ReplyDeleteMark Lorenz, may i know the results of this study? have you proven your hypotheses? was it possible to make plastic from talahib? answer asap. thanks! :] -- Komiko Sugauchi
ReplyDeleteHi Komiko..did you find the research..?thanks.
DeleteHi Komiko Sugauchi! You may see the whole paper at DOST Taguig. You can see the results there and how the hypotheses were proven.
ReplyDeleteHi mam...is it really on the DOST Taguig cause we're planning to go there for the results? Are there any requirements. Thanks.- Mel Anacion
ReplyDeleteOn what department shall we go for the results mam..?thanks.
ReplyDeleteHow to measure the tensile strenth
ReplyDelete?
How to measure the tensile strenth
ReplyDelete?
how have you measure the tensile strength of your plastic???
ReplyDeleteRIP Mark Lorenz...
ReplyDeletewhat is the result of this study????
ReplyDeleteHello.. Talahib is also our material for our study. May I know what particular season/ month have you cut talahib and.. where? Thanks :D
ReplyDeleteI think it is around October to February
DeleteUhmm.. just want to say thanks to the researchers of this study 'cause i've got a new bright idea about the Talahib! thanks for the infos!Such a great help!! XD
ReplyDelete--- Lady Mystique
pahiram lang po, d ko po sya gagayahin, guide lang po, salamat :)
ReplyDeleteGood day! Can you give us some tips to conduct this research plan? This is kinda interesting and sounds so useful! Kudos to the researcher who came up with this :D
ReplyDeletehey, bro.. thanks for the help... :)
ReplyDeletewhere did you buy polyvinyl alcohol?
ReplyDeletehi po! hiramin ko po siya para may pang-guide ako! thank you!
ReplyDeleteWhat compound of talahib makes it appropriate for making biodegradable plastics?Im also aiming to make the same product its just that im going to use other raw material.Thank You
ReplyDeletethank you for giving me an idea.. it will help and guide me a lot in my science investigatory project for competing in science fair event
ReplyDeleteCan i ask for the whole info of the project
ReplyDeleteCan I see the whole S.I.P ?? please?? please send in my gmail khryssf@gmail.com thank you so much po
ReplyDeleteCan talahib be used for construction (such as concrete, beams, etc.)? Im just curious about its tensile strength.
ReplyDeleteAhm, Can I a question? What did you use? The Cellulose or starch content of the grass?
ReplyDeleteWhat are the components of talahib pulp that would make the research possible?
ReplyDeleteI humbly ask if there are any loopholes on this research?
ReplyDeleteCan I ask for your research recommendations? Only for my assignment in research.
