QUALITY CONTROL OF RAW MATERIALS FOR CANDIED CARICA USING P-CHART ANALYSIS AND FISHBONE DIAGRAM

Abstract

Carica is a plant that can only grow in the Dieng area of Wonosobo. This causes raw materials only to be obtained in the Wonosobo area. The number of Carica processing efforts, causing entrepreneurs must be able to optimize the quality of raw materials. One of the companies that process Carica is a CV.
