Corn Stalks Material Value Conservation as Main Material for Particle Board

Abstract
The production of corn plants which increases every year produces corn waste such as corn stalks. Mostly, corn stalk wastes are left and burned thatcould make some environment issues. Therefore this study aims to increase the value of corn stalk waste material by using corn stalks as the main material for making particle boards that can be produced for an industrial scale. This research was carried out by making particle boards using the main ingredients of corn stalk with Urea Formaldehyde (UF) and Phenol Formaldehyde (PF) adhesives, each adhesive using a concentration of 8%, 10% with hot press temperature 130 ℃ and 150 ℃. Then the testing includes physical and mechanical testing based on SNI standard (Indonesian Standard) requirements. This research uses design of experiment as the method. The best results obtained were the composition of the corn stalk using PF adhesive type, with 8% concentration and hot press temperature 130 ℃ because the composition was included in the SNI type 8 The results also explained that there was a significant improvement from the previous corn stalk that mostly wasted and non-valuable as a material that can provide economic benefits Index Terms - Corn Rod, Particle Board, Design Of Experiment, Urea Formaldehyde (UF) and Phenol Formaldehyde (PF)
