ABSTRACT Dissolving pulp is a pulp that has a higher quality than pulp in general. One of the features of dissolving pulp is that it has an alpha cellulose value of at least 94% (SNI 938: 2017 - Pulp Rayon). While the kraft pulp Eucalyptus pellita made by pulp machine also comprises 92% alpha cellulose. Therefore, this study was conducted to analyze the results of the dissolving pulp manuf…
ABSTRACT The dechlorination process in the brine tank is a process to remove the remaining chlorine dissolved in the weak brine solution using sulfur dioxide (SO2) as a reductant. SO2 solution is a solution formed when sulfur dioxide gas (SO₂) dissolves in water (H₂O), colorless with a pungent odor. Concentration is the amount of a solute in a homogeneous mixture (solution). The methods us…
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 com…
Avocado fruit (Persea americana Mill.) has high nutrition such as healthy fats, fiber, vitamin E and vitamin C.
