UTILIZATION OF RICE HUSK AS A MAIN COMPONENT OF LOW-COST PLYWOOD

Abstract

This study explores the feasibility of using rice husk as a primary component in plywood production. Rich in cellulose, hemicellulose, and lignin, key elements in plywood manufacturing, rice husk presents a sustainable alternative to traditional wood-based materials. The motivation behind this research stems from the increasing need for eco-friendly solutions and the ongoing depletion of natural forests. By utilizing agricultural waste, this study aims to contribute to sustainable material innovation while promoting environmentally responsible alternatives for writing and drawing surfaces. This study employs a quantitative-descriptive research design, selecting five (5) civil engineers and five (5) plywood manufacturers as participants through purposive sampling. To address the research questions, data was gathered using a survey questionnaire. The analysis utilized statistical tools such as the weighted mean, a 4-point rating scale, and the t-test. The overall acceptability of natural ink was rated as Acceptable based on key factors such as material composition, insect resistance, cost-effectiveness, durability, and presentation. The civil engineers’ assessments yielded an overall weighted mean of 3.02, with a variance of 0.1258, a t-computed value of 0.2067, and a t-critical value of 2.306 at α = 0.05. Similarly, plywood manufacturers reported a weighted mean of 3.06, with a variance of 0.058, a t-computed value of 0.2067, and a t-critical value of 2.306 at α = 0.05. These results indicate no significant difference between the evaluations of the two groups. Given the positive reception from both civil engineers and plywood manufacturers, there is strong potential for the widespread adoption of rice husk as a primary component in low-cost plywood production. For further enhancement and improvement of the product, civil engineers and plywood manufacturers provided the following recommendations: explore alternative materials that can enhance the quality of the plywood and incorporate an effective insect repellent to increase its longevity while maintaining cost efficiency.
