The study aims to conduct and make a useful product for car windshields and for windows of buildings out of Apitong sap.
To conduct the experiment, the researchers first gathered apitong sap and acetone. The acetone is boiled together with the sap in a ratio of 8 30ml of apitong sap is to 1 30ml of acetone. After boiling, the researchers transferred it to an empty container. After a few minutes, the container was exposed in the air so that the sap would hardened. A few hours after, the sap with acetone turned into fiberglass.
Durability of the fiberglass was conducted by breaking the product. Based on the data and T-test computation at 0.5 level of significance with degree of freedom, T-value is -0.91959 lesser that the P-value which is 2.306. This implies that there is significant difference between the experimental fiberglass and the typical kind of fiberglass sold in the market.
