Significance of the Study
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

Scope and Limitations – 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.

Background of the Study

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.

Abstract

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.

 A. Background of the Study

              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.
