Currently, the world's need for paper is around 394 million tons, the growth in world paper demand is estimated to grow by an average of 2.1 percent per year so that the paper industry is required to produce paper in accordance with production targets and meet the paper quality set by Riau Andalan Kertas (RAK) technical. One way to achieve production targets is to minimize lost time and reduce paper rejects, because if there is lost time in a production process, it will cause various losses that must be faced, for example, rejected products. There are several causes of lost time in the paper industry, one of which is lost time shade change. Shade change is the process of changing the color, whiteness and brightness values on paper. Therefore, several strategies are needed during the shade change process, including (1) starting / stealing the start shade change 4 minutes before the jumbo roll / turn up change. (2) changing the flow dye and Optical Brightness Agent (OBA) controls to manual. (3) adjusting the flow dye with the dose broke. (4) adjusting OBA flow with Precipitated Calcium Carbonate (PCC) usage. (5) increase the flow dye and OBA gradually to prevent overshoot.
