Merced This study was conducted at Muzon 2, Sapa 3, and Tejeros Convention in Rosario, Cavite from December 2010 to February 2011. With the objective of determining if there is a significant difference between water hyacinth as an alternative material in making pin board when compared with the commercial cork board in terms of pin penetrability, appearance, texture, durability, water absorption. The Randomized Complete Block Design (RCBD) was used in the study with three treatments and two replications. The treatments were: To - control (commercial cork board), T; - pin board made from 25 grams of water hyacinth and 100 grams of wood glue, T2 - pin board made from 50 grams of water hyacinth and 100 grams of wood glue, T3 pin board made from 75 grams of water hyacinth and 100 grams of wood glue. The Analysis of Variance (ANOVA) was then used for test significance. Based on the findings of the study and with the use of descriptive analysis, it was found out that the treatments used can be an alternative pin board. The ANOVA table showed that there is a significant difference between the commercial pin board and the water hyacinth board in terms of their penetrability, appearance, texture. Therefore, the null hypothesis was accepted. With respect to the durability, based on test conducted, it was found out that all the treatments have a significant difference in comparison to the control group. Therefore, the null hypothesis is rejected. In water absorption as also based on the test conducted, TiRz was found out to have no significant difference with To. The null hypothesis is then accepted ER -
