Abstract

Corn is a useful plant that is widespread throughout the country, including Indonesia. This plant is one source of carbohydrate food to the people in Indonesia. One part of this plant in the form of corn husks are often used as animal feed. Corn skin contains cellulose that can be used as an alternative raw material in the manufacture of pulp. The pulping process used in this study is the process of soda, which is releasing corn husk fibers with sodium hydroxide solution by using a digester. This study aims to determine the effect of concentration cookers and cooking temperature on the quality of the pulp produced. The variables used in this study is a 7% concentration cookers, cooking temperature 90°C, cooking time 80 minutes and 11% concentration cookers, 110oC cooking temperature, cooking time 80 minutes. Results pulp is analyzed to obtain moisture and cellulose α levels. The results show the best pulp at 7% concentration cookers, cooking temperature 90°C and cooking time 80 minutes with a water content of 33,00% and cellulose α levels 39,33%. Keywords : Pulp, corn husk, cooking temperature, cooking time
