The Problem
Background of the Study
Inventions have evolved and continue to evolve such that after several years of study, research
and experimentation reach great developments. With continuing efforts to investigate the other use of
different plants in our country, the proponents made some research about
taro bark as main
component in glue-making. Nowadays one of the commonly used materials in school is glue. Because of
these reasons the proponents try to investigate the use of taro bark as glue.
Environmental consciousness is one factor that researchers seek uses of wasted materials. And
one of those waste materials, especially in the market, is the taro bark. Since taro bark contains many
characteristics similar to different starch used in glue-making process, the researchers used this as the
source of starch in glue. It has many advantages compared to commercial glues in the market. One of
these advantages is, that taro bark is abundant in nature and renewable - almost having an unlimited
resource. Also, it is organic and a safe material in making glue. Aside from its environmental-friendly
nature, it is also cheaper compare to other commercial glue. It is cheaper because its main component is
a waste material. This organic glue was also hoped to have the same characteristics as commercial glue.
The proponents were interested in making organic glue, for glue is one of those things that are in
demand with the students and to other people. With this study the researchers hoped to produce
organic glue out of waste taro’s bark.
Significance of the Study
The study will be significant in promoting environmental consciousness. This study will be
beneficial to the Gabi growers because instead of selling the plant to the market, now there will be a
new product from their plant that will give them new income. This study may also help the students,
teachers and other employees and in the other fields that uses expensive commercial glues. The product
will also lessen the scattered gabi plants in the streets after the strike of typhoons.
Moreover, the study will be helpful to the wholesalers who always buy the branded product of
glue that usually cost 40 pesos. Moreover, this study will teach buyers to be practically minded in
spending money.
Statement of the Problem
The researchers want to find out if gabi bark starch is effective to use as a main component of organic
glue. Specifically the researchers seek to answer the following questions:
1. What is the best amount of Gabi barks’ starch to use as a main component of organic glue?
2. How does the experimental glue differ from the commercially available glue in terms of:
a. Stickiness
b. Odor
c. Reaction to skin
d. Over-all acceptability
Hypothesis
1. There is no significant difference among the different amounts of gabi bark’s starch in
making organic glue.
2. There is no significant difference between the experimental glue and the commercial glue in
terms of stickiness, color, reaction to skin and over-all acceptability.
Definition of Terms
Adhesive - is a mixture in a liquid or semi-liquid state that adheres or bonds items together.
Bark - is the outermost layers of stems and roots of woody plants. Plants with bark include trees,
woody vines and shrubs.
Commercial – branded products
Component - is a substance that forms part of a mixture (in a general sense).
Environment - refers to the surroundings of an object
Gabi plant - is a common name for the corms and tubers of several genera of the famil Araceae The
name includes species of Colocasia spp (dasheen, taro, cocoyam, eddoe) Alocasia spp (giant
taro).
Odor - is caused by one or more volatilized chemical compounds, generally at a very low concentration,
that humans or other animals perceive by the sense of olfaction.
Reaction to skin – effect to the skin
Residue - refers to the material remaining after a distillation or an evaporation, or to a portion of a larger
molecule, such as a methyl group. It may also refer to the undesired byproducts of a
reaction.
Starch - is a carbohydrate consisting of a large number of glucose units joined together by glycosidic
bonds.

Review of Literature
Conceptual Literature
Taro (pronounced /ˈtɑroʊ/) is a common name for the corms and tubers of several genera of
the famil Araceae The name includes species of Colocasia spp (dasheen, taro, cocoyam, eddoe) Alocasia
spp (giant
taro), Amorphophallus
campanulatus (Roxb)
(elephant
yam)
and Crytosperma
chamissons (Shott) and the tropical American Xanthosoma sagittifolim (Shott). Of all the edible aroids,
Taro as Colocasia esculenta is the most widely cultivated and native to southeast Asia. It is a perennial,
tropical plant primarily grown as a root vegetable for its edible starchy corm, and as a leaf vegetable and
is considered a staple in African, Oceanic and Asian cultures. It is believed to have been one of the
earliest cultivated plants. Colocasia is thought to have originated in the Indo-Malayan region, perhaps in
eastern India and Bangladesh, and spread eastward into Southeast Asia, eastern Asia, and the Pacific
islands; westward to Egypt and the eastern Mediterranean; and then southward and westward from
there into East Africa and West Africa, from whence it spread to the Caribbean and America. It is known
by many local names and often referred to as Elephant ears when grown as an ornamental plant.
Adhesives
An adhesive, or glue, is a mixture in a liquid or semi-liquid state that adheres or bonds items
together. Adhesives may come from either natural or synthetic sources. The types of materials that can
be bonded are vast but they are especially useful for bonding thin materials. Adhesives cure (harden) by
either evaporating a solvent or by chemical reactions that occur between two or more constituents.
Adhesives are an advantageous for joining thin or dissimilar materials, minimizing weight, and when a
vibration dampening joint is needed. A disadvantage to adhesives is that they do not form an
instantaneous joint, unlike most other joining processes, because the adhesive needs time to cure.
The earliest known date for a simple glue is 200,000 BC and for a compound glue 70,000 BC.
Stalk’s special processing delivers a delicious patty. The purple color in variety comes from the
same substance that gives red wine its color and antioxidant properties. This include the following
nutritional benefits: (a) high in complex carbohydrates and fibers,(b) excellent source of potassium and
calcium iron and vitamin A, (c) Non allergic and Low fat and (d) a low glycemic index.
An adhesive or glue is a mixture in liquid or semi liquid state that adheres or bonds

Stalk are passed through a series of water baths. The stalk is cooked either by boiling.
The resulting liquid is extracted and reheated again to thicken the glue. The glue can be chilled
into either sheets on blocks then suspended on nets to dry and become still more concentrated.

(include here the research made by Cristina velasco and group (jackfruit seed as paste, and the research
made by Jerome – taro peeling as bioplastic)
Synthesis
Based on the two literatures, the researchers would try making organic glue out of taro bark.
