Abstract

The purpose of this study was to determine the effect of soaking time in alkali and hydrogen peroxide on the change in the diameter of coconut fiber as an environmentally friendly composite material. This research is divided into several steps, namely: preparation of tools and materials, treatment, diameter measurement, analysis and discussion. The equipment used is a set of immersion media, and digital microscopes while the materials used include alkaline solutions, hydrogen peroxide solution, distilled water, and coconut fiber. Coconut fiber was soaked for 1, 3, 5, 7, 9, and 11 hours in an alkaline solution with a concentration of 10%, then dried for 5 hours in a furnace at 90oC. Furthermore, coconut fiber was soaked again for 1, 3, 5, 7, 9, and 11 hours in a solution of potassium permanganate with a concentration of 0.5% then dried for 5 hours in a furnace at 90oC. Then the coconut fiber was soaked again for 1, 3, 5, 7, 9, and 11 hours in a hydrogen peroxide solution with a concentration of 10% then dried for 5 hours in a furnace at 90oC. The next step is to measure the diameter of the coconut fiber using a digital microscope. In accordance with the measurement results obtained, it can be concluded that the soaking time of coconut fiber in alkaline solution, potassium permanganate, and hydrogen peroxide causes degradation of diameter after soaking. The highest percentage of diameter degradation of 58.08% occurred in the third treatment.
