2. RATIONALE
The world is facing the crisis of fossil fuel
depletion. Fossil fuel provides a large
amount of the world’s primary source of
energy. The demand of energy in the
Philippines has increased also because of the
small and insufficient reserve, leading to the
depletion of oil reserves and especially the
destruction of the environment that may
lead to terrible disasters or global warming.
3. Alternative resources of energy are
developed and these includes Bio-
briquette.
Bio-briquettes are renewable energy source
that are used in different industrial boiler
applications and can also be an alternative
to coals or charcoals. Bio-briquette also
helps conserve the massive use of fuel
which also prevents deforestation.
5. STATEMENT OF THE PROBLEM
1. What process does Swietenia macrophylla dried
leaves undergo to produce a bio-briquette?
2. Is there a difference between Swietenia macrophylla
dried leaves and wood charcoal in terms of:
2.1 Time interval of boiling point
2.2 Color of the flame
6. OBJECTIVE OF THE STUDY
1. Determine the process of Swietenia macrophylla
dried leaves should undergo to produce Bio-
briquette.
2. Find out the difference between Swietenia
macrophylla dried leaves and wood charcoal in terms
of:
2.1 Time interval of boiling point
2.2 Color of the flame
7. HYPOTHESES
H0 There is no difference between
Swietenia macrophylla dried leaves as bio-
briquette and wood charcoal in terms of the
time interval of the boiling point and color
of the flame.
H1 Swietenia macrophylla dried leaves can
produce a bio-briquette through the process
of air-drying.
9. SCOPE AND LIMITATIONS
This study is only limited to the
production of bio-briquette from
Swietenia macrophylla dried leaves,
which was covered from July 22, 2019 to
September 30, 2019. It is performed only
in the locality, particularly in the
laboratory of Calubian National High
School.
10. DEFINITION OF TERMS
Bio-briquette – are compacted brick-shaped
mass of usually fine material; ultimate source
of energy used for cooking at home and in
industrial places.
Swietenia macrophylla – are species of plant
in the Meliacaeae family and it is one of three
species that yields genuine mahogany timber.
Fossil fuel - fuel formed from decomposition
of buried dead organisms, containing energy.
13. The researcher collected Swietenia macrophylla dried
leaves weighing 2 kilograms and then burned these in a
metallic container until it turned to semi-ash.
After it turned into semi-ash, the researcher crushed it
using mortar and pestle and set it aside for cooling. After
cooling, the burned and crushed leaves was mixed with 2
cups of water. When it was done mixing, the researcher
prepared and improvised mold made out of cut tube and
started briquetting, compressing the burned and crushed
leaves into the mold thoroughly in order to have no gaps
underneath, and removed it from the mold afterwards and
finally dried the Swietenia macrophylla briquettes for 3-6
days.
14. RESEARCH LOCALE
This study was conducted at the laboratory of Calubian National
High School in Calubian, Leyte.
RESEARCH SUBJECT
The subject of this study is the production of bio-briquette derived
from Swietenia macrophylla dried leaves.
RESEARCH INSTRUMENT
The instrument used in this study was the amount of water and
wood charcoal for the control variable and the same amount of water
and Swietenia macrophylla Bio-briquette for the experimental
variable.
15. DATA GATHERING PROCEDURE
Prior to the conduct of the experiment, the researcher secured a letter of
permission to the school principal of Calubian National High School for her approval
to conduct the study.
The initial step in gathering the data was the process of producing bio-briquette
for 2 weeks. Lastly, the testing of the product whether the Swietenia macrophylla
dried leaves as Bio-briquette works or unable to do its purpose.
PLANNING
On July 19, 2019, the researcher thought about the processes on how she can
come up with a functional and successful bio-briquette, with the help of her
Research adviser giving her suggestions on how to produce a product.
In the same month, July 22, 2019 the researcher finalized her research study
and started to collect the materials needed, specifically the dried leaves of
Swietenia macrophylla.
16. RESULTS AND DISCUSSION
This chapter describes the data gathered
corresponding to the different variables
determined by the experimental study.
As the method of producing Bio-briquette
from Swietenia macrophylla dried leaves
terminated, it was proven that air-drying
can be an effective process of generating
these renewable source of energy.

19. SUMMARY OF FINDINGS
Based on the results of the experiment, the following
are the findings: Swietenia macrophylla can produce a
bio-briquette through air-drying; there is a difference
between the Swietenia macrophylla Bio-briquette and
wood charcoal in terms of the time interval of the
boiling point and color of the flame. The water boiled
using the wood charcoal boiled in 10 minutes
producing an orange-colored flame, and the water
boiled with the Swietenia macrophylla Bio-briquette
boiled in 12 minutes and produced a blue-colored
flame.
20. CONCLUSION
1. Swietenia macrophylla dried leaves
can be produced into Bio-briquette
through the process of air-drying.
2. There is a difference between the
time interval of the boiling point and
flame color of both wood charcoal and
Swietenia macrophylla Bio-briquette.
21. RECOMMENDATIONS
1. Further research on how to improve the
production of biogas from Swietenia macrophylla
dried leaves.
2. School should encourage and provide
opportunities for students and teachers by
sending them to seminars or workshops that
would enhance their knowledge about other
related researches.
