ACKNOWLEDGEMENT
In the name of Allah, the Most Gracious and the Most Merciful. Praise to Allah this project
has successfully done.
First of all, I would like to convey greatest gratitude to my eloved parents and family who
always supports and have faith in me to conduct this project. !hank you and high
appreciation I would like to e"press to the most determined Prof. #r. Fu$iah inti %ulaiman
who works as a lecturer in &niversiti !eknologi MA'A. (e"t, I would also like to say thankyou to my educated advisor, Ms. %iti (a$irah inti Au )akar and also Ms. %ya$lina inti
%amsudin who always there to give me full inspiration without any hesitation.
(ot to forget my lovely relatives and friends who always give full confidence in me
throughout completing this project. *astly, I am very grateful to the principal and the school+s
authority for elieving in me and giving me the courage to succeed in this project. !hank you

ABSTRACT
A PRELIMINARY STUDY OF CITRUS SINENSISAND GARCINIA MANGOSTANAPEELS AS A GREEN SOURCE OF ELECTRICITY
(ur %haira Adlin inti (asari
M'%M Merok, edah
Fruit peel wastes like Citrus Sinensisand Garcinia Mangostanapeels had contriute negative
impacts to the environment whereas chemicals in dry cells will cause detrimental effects on
health and the environment. 'esearch had shown Citrus Sinensisand Garcinia Mangostana
peels produce voltage in compressed condition.
!he Citrus Sinensis and Garcinia Mangostanapeels were grinded and dried in - hours
duration. !hese peels have een compressed in marker pen caps of e/ual si$es. Magnesium
and copper electrode were dipped into the compressed Citrus Sinensis and Garcinia
Mangostanapeels. !he readings were measured using multimeter. )ased on the e"periment,
the use of replicated and doule compartments of compressed Citrus Sinensisand Garcinia
Mangostanapeels will produce doule of the voltage. !he compressed Citrus Sinensis and
Garcinia Mangostanapeels in a marker cap produced 0.1 2 while five marker cap of e/ual
si$e will produce 3.3 2 to 4.4 2.
!here are many enefits of this project that can e contriuted to the scientific community.
Firstly, this project is environmental friendly which will reduce the amount of solid wastes in
the world wide. %econdly, this project is completely harmless as it is non5to"ic and non5
chemical content. !hirdly, the Citrus Sinensis and Garcinia Mangostana peels
environmental5friendly attery is portale. *ast ut not least, as we know the chemical
attery nowadays were costly ut this project guarantee a low cost and environmental5
friendly attery.
