Abstract
Waste is a material that is discarded or wasted from the results of natural or human activities that do not yet have economic value. One type of waste is agricultural waste. Agricultural waste is waste generated from agricultural activities such as fruit harvesting. Examples of agricultural waste include coconut leaves, corn leaves, rice straw, coconut husks, banana stems, and reed leaves. Reed plants is one type of grass plant that can grow on land that has moist or dry characteristics. Art paper is a handicraft product made from fibers derived from plants. Plants used as the basic material for making art paper are plants that contain cellulose. In the process of making paper, the beginning of the process is delignification. This study aims to obtain the optimum treatment in each process of delignification of reed leaves. The analytical method used is the Response Surface method using two factors: CH3COOH concentration of 85%, 90%, 95% and cooking times of 30 minutes, 60 minutes, and 90 minutes. The optimum treatment for the delignification of reed leaves obtained 90% CH3COOH concentration with a cooking time of 60 minutes.
