This study uses time series data, in the form of rubber production data during March 2012 - February 201, that were analyzed descriptively using Control p Chart Analysis. Control p Chart describe the proportion of production damage that can be tolerated as a tool for statistical Control p Chart Application as Quality Control Tools for Rubber Production in PTPN IX Batujamus/Kerjoarum process control. This study shows that the quality of the rubber produced by PTPN IX (Persero) Garden Batujamus/ Kerjoarum is out of the control. The Control p Chart proves that there are still many points that are outside the production control line.
