Analisis Pengaruh Penambahan Dosis Cationic Starch Terhadap Dewatering Dan Strength Properties

---

ABSTRACT
Dewatering process and paperboard strength are critical parameters in the production of paperboard. A slow dewatering process can limit production rates and increase energy costs, while low paperboard strength can reduce product quality and application. The objective of this study is to analyze the effect of adding cationic starch dosage on these two parameters. Cationic starch, a common ingredient in paperboard production, is expected to enhance fiber and filler retention, thereby improving paper strength properties. In this study, varying doses of cationic starch (0, 3, 6, 9, 12, 15, and 18 kg/T) were added to the stock pulp. Dewatering performance was analyzed using a manual measurement of the Schopper-Riegler freeness (SR). The paperboard strength properties analyzed included internal bonding and folding strength. The results demonstrated that the incorporation of cationic starch at a dosage of 6 and 9 kg/T significantly enhanced the dewatering process, with the fastest drainage time recorded at this dosage (11.81 and 12.11 seconds/500 mL). As the dosage of cationic starch increased, both internal bonding and folding strength showed a corresponding increase. However, it is crucial to optimize the cationic starch dosage to achieve optimal dewatering efficiency and superior paperboard strength.
Keywords: cationic starch, drainage, folding strength, internal bonding
