Introduction

Background of the Study
To produce paper, it is necessary to cut down trees. Nearly 4 billion trees or 35 percent of the total trees cut around the world are used in paper industries on every continent (Martin, 2011). But, many studies were conducted that non-woody plants especially grasses have the potential to be materials in making paper. Paper made of grasses requires much less processing than wood-derived paper, and is far better for the environment. Anyone who’s ever visited a pulp mill can attest to the unpleasant smells, and moreover, turning wood into paper releases harmful chemicals like dioxin (Striepe, 2011). Cogon grass (Imperata cylindrica) forms a dense mat and produces plenty of leaves that make it nearly impossible for other plants to coexist. It can invade and overtake disturbed ecosystems by displacing a large variety of native plant species. It is a very strong competitor for water, nutrients and light because it sprouts and grows faster than most crops (Sherley, 2000). Papermaking is the process of manufacturing paper, a substance which is used ubiquitously today for writing and packaging. In papermaking, a dilute suspension of fibers in water is drained through a screen, so that a mat of randomly interwoven fibers is laid down. Water is removed from this mat of fibers by pressing and drying. Most paper is made from wood pulp, but other fiber sources such as cottons and textiles may be used (Surhone, et al., 2010).   Cogon grass basically consists of cellulose fibers, hemicellulose and lignin which are common to non-wood pulps especially grasses (Hurter, 2001). Thus, this study was conducted to determine the feasibility of cogon grass as a material in paper making.

Statement of the Problem
The researcher aimed to determine the feasibility of cogon grass (Imperata cylindrica) as a material in paper making. Specifically, it sought to answer the following questions: 1. What is the feasibility of Cogon grass (Imperata cylindrica) as a material in paper making in terms of tensile strength? 2. Are there significant differences on the feasibility of Cogon grass (Imperata cylindrica) and rice straw as materials in paper making in terms of tensile strength?

Hypothesis
There are no significant differences on the feasibility of Cogon grass (Imperata cylindrica) and rice straw as materials in paper making in terms of tensile strength.

Significance of the Study
This study would be beneficial to the following:
Paper Manufacturers. Paper manufacturers would engage in using cogon grass as a material in paper making instead of wood or other expensive materials. Students and Teachers. Students and teachers would save money because paper from cogon grass is cheaper compared to other paper made from other materials. People of Leon. People of Leon would have source of income because cogon grass can be found anywhere in the community.

Scope and Limitation
This research was only limited on the use of 500 grams of cogon grass as a material in paper making. It consisted of two treatments (cogon grass and rice straw) with two replications. 10 samples were done in each replications. It was conducted in Barangay Talacu-an, Leon, Iloilo from August 1 to August 7, 2011. The researcher used stones to determine the tensile strength in terms of kilograms. The use of stones limit if the paper is torn.

Definition of Terms
The following terms were given conceptual and operational definitions for a clearer understanding of their use in the study. Feasibility. Capable of being used or dealt with successfully (Elliot, 1995). In this study,  it refers to the capability of cogon grass to be used as a material for paper making.

Cogon grass (Imperata cylindrica). Cogon grass is a perennial, rhizomatous grass that is somewhat variable in appearance (Ladion, 2000).
In this study, cogon grass was made as a material in paper making. Paper. Paper is a substance in sheet form...
