KARAKTERISTIK ANATOMI KULIT BATANG SAGU (Metroxylon sagu Rottb.) UNTUK BAHAN BAKU PULP DAN KERTAS

Abstract

The study aims to analyze the anatomical characteristics and values of fiber derivatives as raw materials of pulp and paper, samples in the form of sticks the size of matchsticks are prepared for measurement of fiber dimensions then inserted into the test tube and added a chemical solution until the sample is submerged. The test tube is heated to a boil and is yellowish- white. Samples are cooled and washed with aquades. The sample is colored with safranin. Based on the results of research on the value of sago skin fiber derivatives if the average runkel number is obtained worth 1.18, with a class 4 weaving power category of 38.82 with a class 4 category, musteph rotio worth 38.43% with class 2 category, coefficient of rigidity worth 0.26 with class 4 category and flexibility ratio of 0.45 with category 3, Based on fiber classification value can conclude that sago skin is included in class 3 category.
