Turnitin: nalisis Kandungan Kimia Jelutung (Dyera costulata) berdasarkan Posisi Ketinggian Batang

Abstract

This study aims to determine the color of a sample qualitatively on jelutung wood including the base, middle, tip, and bark. Changes in color using a photometer are not only found in every type of wood, but also affect the position of the height on the stem. Color changes are generally influenced by extractive composition, temperature, humidity, light, and storage conditions (Sahin 2011). The color of the wood needs to be considered for pulp and paper, because the brighter the color of the wood, the better the quality of the pulp and paper produced. Jelutung wood has a smooth texture, the direction of the fibers is straight, and the slippery surface is slightly glossy so it is suitable for writing paper. And it can also be used as pulp and paper with the addition of chemicals and advanced treatment. Color change usually occurs due to the presence of substances that react before and after treatment on a sample.
