Background of the ResearchFood is the main ingredient needed by all living
things on earth. Living things can not survive by anymeans without the food. Food has a variation, in terms ofboth form and its content. Examples Protein. Protein isone of the important factors for the body, which work toimprove the body's cells are damaged. Daily food
containing egg protein example.Eggs including foodstuffs daily consumption
figures, particularly in Indonesia. Eggs are commonlyconsumed chicken eggs and duck eggs. However, manycomplaints arise from a breeder laying hens. They often
find that the eggs is rotted before the eggs sold ifconditions did not sell. While wearing the refrigerator isan ineffective and costly of the electricity used. So it isnecessary as an alternative way that can be easy to useand cheap.

ExperimentAn experiment that seeks to influence a particular variable to another
variable in strictly controlled conditions.How ? : by performing experiments directly to get accurate data.
Research DesignResearch is underway to create a simple way to preserve the eggs that
have a way of working to close the pores of the egg shell, to know how to
work a simple tool, as well as to see if how the simple tool is also affectedby the room temperature.Variable :

Procedure Prepare tools and materials
Prepare eggs and put to the cups ex-mineral water. Give label on each cups:
A : Origin Egg (No preserver material)
B : Egg with cooking oil
C : Egg with Margarine
D : Egg with Vaseline Give each egg with preserver material, based on the label
Put all of eggs to room with normal temperature.
Observe it every week.

Conclusion:
I did this experiment for 7 week. In this experiment, can conclude
that Vaseline and margarine are most effective materials on preserving
the eggs. Cooking oil just can preserving the egg 1 week longer time
than normally egg. Vaseline and Margarine can form more thickness
layer than cooking oil. Cooking oil difficult to forming thickness
membrane because cooking oil easy to melt.
