Larvicidal Activity of Pineapple Peel (Ananas comosus) Ethanolic Extract against Aedes aegypti1.4 Statement of the ProblemThis study aims to determine the larvicidal activity of Ananas comosus peel ethanolic extract against Aedes aegypti larvae.With the application of this study, the researchers strive to decrease death rates caused by the diseases brought by Aedes aegypti mosquitoes. Having a healthy and constantly growing population leads to having a larger number of outstanding, highly effective workers and a greater domestic market. Larvicides also play an important role in mosquito control, it helps in preventing the reduction of real estate values, and the negative impact of mosquitoes on livestock and poultry production. Also, organic larvicides are proven to be more beneficial to the environment than inorganic larvicides. The researchers aim to help other future researchers that have an interest in studying about effective larvicides and are also hoping to be able to help a huge population of people.The following specific questions will be answered by the end of the study:1. What is the relationship between the concentration of Ananas comosus peel ethanolic extract and the number of Aedes aegypti larvae killed?2. What is the relationship between the time of exposure to the Ananas comosus peel ethanolic extract and the number of Aedes aegypti larvae killed?3. How will the concentration of Ananas comosus peel ethanolic extract and the time of exposure affect the mortality rate of the Aedes aegypti larvae?___________________________________________________________________________________________________GUIDE QUESTIONS1.

Solution
-
The independent variables in the study are the concentration of Ananas comosus peel ethanolic extract and the time of exposure to the extract.
-
The dependent variable in the study is the number of Aedes aegypti larvae killed, or the mortality rate of the larvae.
-
The variables are related in such a way that changes in the independent variables (concentration of the extract and time of exposure) are expected to cause changes in the dependent variable (number of larvae killed). The researchers are trying to determine if increasing the concentration or the exposure time will result in more larvae being killed.
-
The main problem of the study is to determine the larvicidal activity of Ananas comosus peel ethanolic extract against Aedes aegypti larvae.
-
The sub-problems of the study are:
- To find out the relationship between the concentration of Ananas comosus peel ethanolic extract and the number of Aedes aegypti larvae killed.
- To find out the relationship between the time of exposure to the Ananas comosus peel ethanolic extract and the number of Aedes aegypti larvae killed.
- To determine how the concentration of Ananas comosus peel ethanolic extract and the time of exposure affect the mortality rate of the Aedes aegypti larvae.
