INTRODUCTION
Background of the Study
Any home can have cockroaches. They are scavengers and a health hazard. While walking on spoiled food in garbage containers, they pick up various bacterial organisms on their legs that they can later deposit on uncovered food. Cockroaches themselves are not implicated in the transmission of any diseases. However, many disease-causing organisms can grow and multiply in their guts and can then be deposited on silverware, plates etc. during defecation. For example, cockroaches can pick up disease-causing bacteria like Salmonella on their legs and later deposit them on foods and cause food poisoning. People continuously exposed to dust containing cockroach feces and crushed body parts become sensitized and may show allergic reaction and asthma after repeated exposure to such dust. (http://www.nyc.gov/html/doh/html/ehs/ehscroach.shtml# american) Pest repellent plants are herbs, flowers and vegetables naturally capable of driving away pests, insects and animals through normal organic chemical means. Their leaves and other plant parts contain organic compounds that confuses or pushes away harmful pests. Pandanus amaryllifolius is a tropical plant in the Pandanus (screwpine) genus. The plant is rare in the wild, but is widely cultivated. It is an upright, green plant with fan-shaped sprays of long, narrow, bladelike leaves and woody aerial roots. The plant is sterile, flowers only very rarely, and is propagated by cuttings. In Southeast Asia, Pandan leaves are used widely as a flavoring and also used as a source of fragrance. However, the same fragrance that attracts people is found to be repulsive to cockroaches. Many people in the Pandan's native region use the leaves to repel insect pests. The researcher preferred to used pandan leaves because of its availability and to determine its effect in cockroaches in different preparation of mixture.

Statement of the Problem
This study aims to produce an effective pest repellant using the extract of Pandan leaves. Specifically, this investigatory project aims to: (1.) To know the effectiveness of Pandan extract in different treatment: 1.1 T1- Control

1.2 T2- Boiled extract of Pandan leaves
1.3 T3- Fermented extract of chopped Pandan leaves
1.4 T4- Mixed extract of boiled and fermented Pandan leaves

(2.) Find out the significant difference in the effect of different treatments in terms of: 2.1 Pest Intolerance
2.2 Number of cockroaches repelled

Significance of the Study
If the study “Production of pest repellent using Pandan Leaves (Pandanus amaryllifolius) against Home Cockroach” was conducted and successfully proven, the following person will benefit: To the home owners: The infested house will decrease the population of cockroaches with little or no expense at all. It also helps to avoid diseases that we can get in cockroaches like food poisoning, allergies, dysentery and typhoid. To the community and environment: This will help our community to realize that plants in the environment are not only a herbal plant, food flavorings or a display in our backyard but also to decrease the population of pests. It also helps the environment to conceive how some plants in their environment can alter into useful products To the future researchers: The result of this study will serve as their guide in conducting the experiment related to this.

Scope and Limitation
This study will be conducted to make an effective cockroach repellent through extracting Pandan leaves. The researchers use the method of fermentation and boiling to get the Pandan leaves’ extract. Significant differences...
