Menentukan Dosis Optimum Penggunaan Cationic Starch Terhadap Strength Kertas

Cationic starch, also known as wet end starch, is one of the chemicals used in the papermaking process that plays a crucial role in the quality and runability of the paper machine process. Cationic starch is starch that has been modified to carry a positive charge, enabling it to bind to negatively charged fibers. Due to this property, cationic starch can help improve the strength of the paper being produced. Strength in paper refers to tear strength, tensile strength, burst strength, and internal bonding. In addition to enhancing paper strength, cationic starch also functions to increase fines and filler retention, improve paper machine runability, and serve as an emulsion with ASA (alkenyl succinic anhydride). This study aims to determine the optimum dosage of cationic starch, compare the paper strength values before and after refining, and determine the strength parameter most affected by cationic starch using handsheet samples. The samples used are stock (pulp) before and after refining. The stock will be diluted to a consistency of 1%, then cationic starch will be added. The applied dosage variations are 0, 2, 4, 6, 8, 10, 12, 14, 16 kg/T. Handsheets will be made and tear, tensile, burst strength, and internal bonding tests will be conducted. The results obtained indicate that the optimum dosage is at the 6 kg/T dosage variation, handsheets after refining exhibit higher strength, and the parameter most affected by cationic starch is internal bonding..
Keywords: burst strength, cationic starch, paper, tear strength, tensile strength
