The Feasibility of Chili (Capsicum frutescens) and Kamias (Hedychium coronarium) as Mosquito Killer

Background of the Study:This study is done by the researcher to give importance to the chili and kamias fruit. Not just in food, but the researcher wanted to produce a mosquito killer out of them. For all we know that chili has been tested and proven to be the one good ingredient in mosquito killer making and what if it is added by the acidic property of kamias fruit? The researcher wanted to know the effect of the combined property of each fruit.

Statement of the Problem:

This study aims to determine the effect of the said mosquito killer (chili and kamias). Especially it will answer the following questions:

1) Does the said mosquito killer (chili and kamias) is cheaper than the commercial ones.2) Will this mosquito killer (chili and kamias) can affect the health/kill the person who accidentally took it.

Hypothesis:1) This mosquito killer (chili and kamias) is cheaper than the commercial ones because the materials/ingredients used to produce this is cheap and are abundant in tropical countries like the Philippines.2) Side effects will occur if accidentally taken by anyone.

Significance of the Study:The said mosquito killer (chili and kamias) was made to compete to the commercial ones which were expensive. And help our country, for we have plenty of chili and kamias.

Definition of Terms:antiscorbutic-a remedy for scurvy poisonous-toxic or venomous; harmful;

having the qualities or effects of poison

Scope and Limitations:If this study is already done, not only the poor ones can use it, also the rich ones. Not just because it’s cheaper but also on its effectiveness.

Methodology:Materials:½ kilo of kamias fruit1 ½ kilo of chilimortar and pestlekettlegas stoveproduct container

Procedure:

The researcher collected and prepared all the materials needed. The researcher then pounded the kamias and chili separately and gets their extracts. After pounding the kamias and the chili, the researcher boiled the two extracts separately for 5 minutes. Then the researcher mixed them and poured them inside the container.

Review of related literature:In the past chili was used only as spices because of its taste. Later on, it was discovered as a good mosquito killer because of its pesticidal property.

While kamias (ginger lily) was also used in food spices before.

Later on,it was discovered by Battistelli in 1939 that it has properties such as astringent, stomachic, refrigerant and antiscorbutic. Some of the researchers now are having kamias as wine but in this study the researcher wants to test the properties of the kamias fruit together with the chili.

Mr. Armando VictorioResearch Adviser Abstract

Pest is an organism that is damaging to livestock, crops, humans, and land. Because of this problem, this study was conducted by the researchers by using garlic and black pepper after they found out that these materials have the ability to control pests. 

The materials were 2 whole garlic, 40 grams of black pepper, 600 ml of water, beaker, Erlenmeyer flask, tripod with wire gauze, alcohol lamp with denatured alcohol, mortar and pestle, knife, chopping board, 4 spray containers, and 150 pests.

There were five treatments tested with three replicates each. Treatment A (garlic only); treatment B (black pepper only); treatment C (mixture of garlic and black pepper);treatment D(commercial pesticide) and treatment E(no pesticide applied) . The researchers used Complete Randomized Design (CRD) as their experimental design and the statistical test of significance used was Analysis of Variance (ANOVA).

After testing, the researchers summarized the results and found out that there is significant difference between the five treatments. And the researchers concluded that garlic and black pepper can be used as an organic pesticide in controlling and irritating pests.

To further improve the study, the researcher recommended the following:*test to determine the right and appropriate amount of the pesticide to be applied *test to determine the effects of pesticide (using garlic only, black pepper only and mixture of garlic and black pepper ) aside from controlling and irritating pests.

Guava Leaves Extract (Component in making soap) treatment for acne [Bathing Soap]Chapter I: 

Background of the study:

Nowadays people are focusing in herbal plants especially those who are common in the

environment. One of the example is the guava plant (Psidium guajava Linn). Based on

research this plant is good for healing and treating wounds and other skin infections. So in

my research I wan't to make a bathing soap out of it, cause I know that it is effective.

People, researchers, scientists were focusing to medicinal plants. They want to prove that

there are plants that are more effective against diseases especially in skin. This study refers

to a plant that can be made into a bathing soap and improves its quality while using this

plant (guava leaves). I want people to handle easily in treating their skin disorders. Instead

of boiling the leaves, now it’s easy to apply. Boiling takes much time. 

Statement of the Problem:

I stated that Guava leaves extract is good for skin. Based on my research, it has many

constituents that is good for skin.

It answers the following questions:

* Is there any constituents of guave leaves that is good for skin?

* What are those?

* It can really treat skin disorders/ Acne?

Hypothesis:

* Guava leaves is good treatment for acne.

* It has many components or constituents.

* Constituents that is good for skin disorders, especially for acnies.

Significance of the Study:

You can make a bathing soap with guave leaves extract as treatment for acne. This plant is

very common to our environment, and aside of its avaibility; it is easy to cultivate. It

contains many components for healing skin disorders.

Scope and Limitation:

The study of guava leaves and getting their extract is often useful. It has the ability to treat,

cure, disinfect skin disorders and capable of being a herbal plant for acnes.
