Applied Research III (General Science Curriculum) Cavite State University. “Coconut Coir Dust and Melted Styrofoam as Alternative Material for Corkboard” Thesis Adviser: Mr. Eduardo Tibayan. Prof. Dulce L. Ramos The research study was conducted at Tambo M. Kulit , Indang, Cavite from June 2002 to January 2003. This aimed to find another source of corkboard in its production, determine the most appropriate amount of coconut coir dust needed; and determine the characteristics that affect corkboard quality. The primary materials such as Coconut coir dust, Styrofoam and Premium Gasoline were prepared and mixed together with specific ratios. The mixture were placed and dried in an improvised molder. The produced corkboards were subjected to a sensory evaluation in terms of texture, color, hardness, flexibility, and general acceptability. It was subjected to five treatments replicated three times. A Complete Randomized Design (CRD) was used in the study. The treatments used were: Ty - control (commercial corkboard); T; - (25 grams of coconut coir dust); T2 - (30 grams of coconut coir dust); Ts - (35 grams of coconut coir dust); and T, - (40 grams of coconut coir dust). Each treatment was mixed with the same ratio of Styrofoam and gasoline (200 grams of Styrofoam is to 50 mL of gasoline). The result showed that To - control — (commercial corkboard) was still the most acceptable among the other treatments. However, the other treatments gained acceptable results, The decreasing order of acceptability is as follows: T, (40 grams of coconut coir dust); T3 (35 grams of coconut coir dust), Tz (30 grams of coconut coir dust); and T; (25 grams of coconut coir dust). The coconut coir dust and melted Styrofoam proved to be an effective substitute material for the production of corkboard.
