<![CDATA[This study examines quality control in chrysanthemum cultivation at Krisan Astritani (Sukabumi) using an Input Process Output (IPO) framework and statistical process control tools (checksheet, Pareto diagram, Fishbone). Quality control is critical because visual consistency (color, flower form, stem strength) directly determines market grade and price; uncontrolled defects increase waste and reduce competitiveness. The research aims to identify main defect types, their frequency, and root causes, and to indicate where corrective effort yields the largest quality improvement. Methods: daily checksheets to record defect types/counts, Pareto analysis to prioritise problems, and Fishbone analysis to trace root causes; these are interpreted through the IPO model. Results: checksheets (n=40 events) revealed dominant defects; Pareto showed three main contributors pest attack (35%), non-sterile growing media (25%), and improper fertilization (20%) which together explain ~80% of defects. Fishbone analysis linked these to material (media, seed quality), method (fertilization & sortation), and human factors (training). IPO summary: Input (media & seed quality) and Process (pest control & fertilization precision) are the priority areas for improvement, with Input as the foundational concern because upstream faults propagate downstream. Implications: focus corrective actions on media sterilization, integrated pest management, SOP-based fertilization, and routine checksheet monitoring to achieve the largest, fastest gains in product grade and waste reduction.]]>
