Quality Control of Mushrooms Canning using Six Sigma Method at Company Y, Pasuruan, East Java

Abstract

Abstrak Tujuan penelitian ini untuk mengetahui pengendalian kualitas pengalengan jamur di PT Y. Penelitian menggunakan metode Six Sigma dibatasi tahap define, measure, analyze dan improve. Tahap improve menggunakan salah satu alat implementasi kaizen yaitu Five M Checklist untuk mengusulkan alternatif perbaikan pengalengan jamur. Hasil penelitian menunjukkan jenis cacat terbesar pengalengan adalah knocked down flange (KDF). Nilai sigma sebesar 3,46, final yield 97,5%, dan kapabilitas proses (Cp) sebesar 1,15. Penyebab KDF adalah pekerja kurang teliti, pekerja kurang memahami standard operational procedure (SOPs) produksi, kesalahan setting up mesin, mesin seamer tidak stabil, komponen mesin seamer aus, bahan kaleng kurang baik dan area produksi tidak nyaman. Alternatif perbaikan yang disarankan adalah memberi arahan dan SOPs training untuk pekerja, mengontrol dan merawat mesin lebih ketat, menjadwal penggantian komponen mesin, melatih dan mengawasi operator mesin, memeriksa bahan kaleng lebih ketat, serta menambah turbine ventilator di area produksi. Kata kunci : final yield, five M checklist, kapabilitas proses (Cp), pengemasan jamur Abstract The study aimed to determine quality control of mushrooms canning in Company Y. The study using six sigma method which were carried out only on the stages of define, measure, analyze and improve. Improve stage was done using one of the implementation tools of kaizen namely Five M Checklist to recommend in improving mushrooms canning. The result showed the highest types of defects in packaging was knocked down flange (KDF).The sigma value was 3.46 with 97.5% of final yield and 1.15 of process capability (Cp. The cause of KDF were the careless of workers, the lack knowledge of the workers on SOP of production, the mistake of machine setting, instability of seamer machine, worn out of seamer machine component, bad canning material and uncomfortable production area. Suggested improvement were giving direction for workers, providing a training of SOP for workers, controlling and maintaining the seamer machine, arranging schedule for replacement of seamer machine components, supervising machine operator, providing machine operator training, performing a more rigorous inspection of cans material and adding turbine ventilators in processing area.
