Abstract
Hyacinth populations that disturb water areas can be reduced by utilizing water hyacinths as raw materials for papermaking because hyacinths have a cellulose content of 24.5% which has the potential to produce good quality paper. The purpose of this study is to determine the effect of raw material size and hydrolysis time on the papermaking process in accordance with ISO 11108: 1996 and SNI 0698: 2010 by varying the size of water hyacinth raw materials namely 0.1 cm, 1-2 cm, and utuh and hydrolysis time of 30, 60, 90, 120, 150 minutes using the reflux heating method. The optimum hydrolysis time and raw material size were obtained at 150 minutes and a variation in the size of the raw material of utuh with a cellulose content of 56.83%, moisture content of 6.01%, and paper tear resistance of 1856.79 mN.
