5.2 discussion results. Science project for comparing the efficiency of charcoal Is intended to compare the efficiency of charcoal with different ingredients of grapefruit Peel. -Corn & coconut, and coconut is the conclusion and discussion results as follows: 5.2.1 to compare the efficiency of charcoal from the charcoal with different ingredients. It was found that the charcoal to heat the most quantity of charcoal with a coconut mixture, heat quantity 8500 calorie that is charcoal that has coconut as ingredients.The most effective, which corresponds to the assumptions. This is probably because coconut is a combustible fuel easier than grapefruit and Peel.-Corn, with coconut charcoal as an ingredient The most effective 5.2.2 the charcoal to heat the second quantity is charcoal that has corn-It is a mixture, the quantity of heat that is calorie 7165 charcoal with corn-A second powerful ingredients from the charcoal with a coconut mixture. This is probably because corn as a fuel-flammable but difficult to peel grapefruit easier.Over coconut, charcoal sticks with corn as an ingredient-efficient than grapefruit Peel. But less than the charcoal with a coconut mixture. 5.2.3 the charcoal to heat the smallest quantity is the charcoal with a mixture.By the quantity of heat that is calorie 6335 charcoal with bark grapefruit as ingredients.The least effective. This is probably because the shells of grapefruit may bring the heat slowly, and makes it difficult to ignite charcoal with grapefruit Peel as the least effective ingredients.
