PEMBUATAN PULP DENGAN METODE ASETOSOLV (PENGARUH RASIO AMPAS TEBU - PELEPAH PISANG TERHADAP WAKTU DELIGNIFIKASI)

The purpose of the study pulping with acetosolve method (the effect of ratio of bagasse and banana frond on delignification times is to determine the effect of time variables and comparition of raw materials composition variables, the composition are bagasse and banana frond on the quality of the pulp produced. The method used for making pulp is a acetosolv method. Acetosolve process is a method of pulping environmentally friendly. This process has many advantages such as high yield, recycled black liquor is easily done and without the use of elemental sulfur making it safer for the environment. Variations in the composition of raw materials used are 0:100, 30:70, 50:50, 70:30, and 100:0. Then, variation of pulp cooking time are 0 hours, 1 hour, 2 hours and 3 hours. Analyses was canducted to determine the quality of the pulp such as yield, cellulose content, kappa number and absorbance. The results obtained in the best operating condition are pulp cooking time for 2 hours and composition 100% of banana frond resulted 99,3% of rendemen, 44,58% of cellulose, 9,96% of kappa number and 0,38 of absorbance
