As a student, this study is important because it can be used in many ways, like art works, decorating, and other school projects. Unlike the other glue, it is not expensive which is an important thing for students
This study the feasibility of the Star Apple Sap as glue. Thus the white glue contains gelatin that is made up of skin, bones and hooves of horses, pigs and cows, but the sap of the star apple is more cheap and more sticky than the ordinary white glue because we can get its sap from it tree or in the actual fruit of Star Apple by squashing it from its peel and it is a common fruit that you can find it easily in the market or in farms.
Star Apple (Chrysophyllum cainito) is a tropical tree of the family Sapotaceae.
It is native to the Greater Antilles and the West Indies. It has spread to the lowlands of Central America and is now is grown throughout the tropics, including Southeast Asia.
The study is entitled Star Apple as a alternative glue .
The white glue contains gelatin that is made up of skin, bones and hooves of horses, pigs and cows, but the sap of the star apple is more cheap and more sticky than the ordinary white glue because we can get its sap from it tree or in the actual fruit of Star Apple by squashing it from its peel and it is a common fruit that you can find it easily in the market or in farms. The extract of the Star Apple (Chrysophyllum cainito) can make glue because it contains an alkaloid, resin, resinic acid and substances that can be use as glue. The researchers aimed at looking for an organic and natural. Ideally, the study promotes a tandem between science and creation’s conservation.
The materials composing the solution were 10 mL of the Star Apple (Chrysophyllum cainito). The set up was composed of experimental and control group. The experimental group was being bond by using a specific commercial glue. On the other hand, the control group was being bond by using the organic glue (Star Apple). Data were collected to gather relevant information. In the end of the findings of the study, it was found out that the solution composing of 10 mL solution of Apple (Chrysophyllum cainito) extract can bond objects in a short span of time compared with the commercial one.
An adhesive is a material, typically liquid or semi-liquid, that adheres or bond items together. Adhesives come from either natural or systematic sources. Nowadays, synthetic adhesive are toxic to humans by sniffing it. It contains toxins that can pose severe risks to health. However, natural adhesives are almost forgotten because it takes time to make and it is not practical anymore, but it does not cause health risks toxins. In this study, researchers will make natural adhesives from two fruits: Lanzones and Star Apple. A Lanzones (Lansium Domesticum Corr.) or maybe known as “Langsat” is one of the most popular fruit in the country. The sap of the skin of the Lanzones is extremely sticky, that it can be a good characteristic of glue.
The Star Apple (Chyrosophyllum Cainito) had its name derived from the star like appearance of the core when the fruit is cut in the cross section. The tough skin surrounds a white, sweet, edible pulp in which are fresh dessert fruit, but care should be taken remove the skin which contains unpleasant-tasting latex. In this study, researchers will focus more on how effective are organic adhesives as an alternate to ordinary adhesives. The purpose of this study is to determine which fruit: Lanzones or Star Apple is a better adhesive.
Which between the extract of Lansium Domesticum Corr. (Lanzones) sap and the Chyrosophyllum Cainito (Star Apple) sap is a better adhesive?
Chrysophyllum cainito is a tropical tree of the family Sapotaceae, native to the lowlands of Central America and the West Indies. It grows rapidly and reaches 20 m in height.It has numerous common names including cainito, caimito, star apple, golden leaf tree, abiaba,pomme de lait, estrella, and aguay.

Material and Equipment
General procedure
-First, you should prepare all the equipment that you will use to our project. Collect as many leaves of a star apple. Then,cut it with the knife. Press the stoke of the leaves. put the extract in the close container. And then repeat the following procedures until the close container will be full.
Result and discussion
-the researcher observe that the extract of a star apple leaves can be use as paste, it is also useful in our community because it contains alkaloid,resin,resinic acid and a bitter substances that can be use as paste. I use the paste from the extract of star apple leaves in paper ,illustration boards and many others.
-There fore i conclude that the extract of Star Apple leaves can be used as paste and it is environment friendly.Like other paste it is also very effective.
-This investigatory project would never been realized without the financial support, effort and unselfish assistance of the people who willingly helped the researcher.In due recognition of all those who contributed to the success of this study.The researcher extend her deep gratitude and heartfelt appreciation to the following:

To my classmates especially Rea Sarino who helped the researcher in her study.]
The economic stability of a nation depends on the availability of the cheap sources of our products. Products from star apple extract are expected to supply part of the country’s economic problem in the future.
For the sake of cleaner environment and to produce products from star apple extract, the researchers decided to explore the potentials of star apple extract as glue. The star apple extract were also tested with water. The glue produced from star apple extract were compared with other commercial glue.
Findings of the study showed effective results in the production of glue from star apple extract. The result was a sticky substance that can be used as a substitute for any commercial glue.
There are many things that can be produced as glue from star apple extract differ from any commercial glue. The most obvious is the fact that glue from star apple extract is cheaper than any other commercial glue.
Therefore, the researchers can conclude that star apple extract can substitute any commercial glue.
