Analisa Pengendalian Kualitas CPO dengan Metode Peta Control pada PTPN III Kebun Rambutan Tebing TInggi

Abstract

Product result are Crude Palm Oil (CPO) and Palm Kernel Oil (PKO). This research purposes area to analyze CPO quality control and factors which cause deviation that influence the CPO quality, using Plan, Do,Check, Action (PDCA) method and supported by seven tools quality control analog with 8 steps problem solving. PDCA is a method which can be used to reduce deviation occurred and diliver qulified product. Then controlling analysis occupied by processing CPO quality standard inspection data, those are level of Free Fatty Acid (FFA), water and impurity using quality tools such as pareto diagram, control chart, and fishbone diagram. The result were compared to qualty standard from company and qualty standard that sets by Badan Standar Nasional (BSN) through SNI 01-2901-2006. Based and pareto diagram analysis, problem priority that will be controlled shown from the high level of FFA reaching 41,1% toward company standard and 57,6% toward SNI. Based and control chart analysis, from the deviation shown problems occurred when using company standard, there were 8 samples out of control limit, while using SNI standard no problems occurred. Based on fishbone diagram analysis by doing field observation and interview there are 4 factors which influence CPO qualty those factors are materials, methods, machines ,environment, and humans.
