Abstract

Betel plant (Areca catechu L.) is a type of palm that is used for commercial purposes because it has high economic value in every part. Areca nut contains cellulose of 53.2%, so it has the potential to be used as raw material for pulp making for paper craft. In making paper craft to obtain brighter colors, bleaching process is needed to attract attention when viewed. During the bleaching process the factors that must be considered are the levels of chemicals for bleach and the length of time during the bleaching process. The purpose of this study was to determine the addition of H2O2 levels and the length of time for optimal bleaching in the manufacture of paper from areca fibers and used packagingcardboard paperboard to produce quality paper craft in terms of physical paper, namely tensile strength, paper thickness, grammager and brightness. Response surface method (RSM) is a collection of statistical and mathematical techniques that are used to develop, improve and optimize the process, where the response is determined to be influenced by several variables that aim to optimize the predetermined response. This method can be applied to chemical processes. The model used in RSM is CCD (Central Design Composite (CDC) using 2 treatment factors, namely the first factor is the length of bleaching time (X1) and the second factor is H2O2 (X2). The first factor uses an upper limit of 90 minutes (X1 = -1) and a lower limit of 150 minutes (X1 = 1). The second factor uses the upper limit of 5% (X1 = -1) and the lower limit of 15% (X1 = 1). The response to be tested is tensile strength and brightness level. In the combination treatment of bleaching time and H2O2, the best treatment was 150 minutes and 15% H2O2. The optimal response results obtained are 69.50% brightness and 14.71 kN/m2 tensile strength. Other physical test results of art paper are 282 gr/cm2, 0.88 mm thickness and 6.5% moisture content.
