Abstract

ABSTRAK Penelitian ini bertujuan untuk menganalisis pengendalian kualitas produk panel bambu di PT Dekor Asia Jayakarya dengan menggunakan metode Six Sigma melalui pendekatan DMAIC (Define, Measure, Analyze, Improve and Control). Selama periode tahun 2024 hingga 2025, perusahaan memproduksi sebanyak 41.290-unit panel bambu, dengan jumlah produk cacat sebanyak 2.541 unit, atau setara dengan tingkat kecacatan sebesar 6%. Nilai ini melebihi standar kualitas perusahaan yang ditetapkan sebesar maksimal 3,5%. Jenis kecacatan yang paling banyak ditemukan meliputi konstruksi pecah (641 unit), bambu berjamur (624 unit), kerapihan paku dan tali (642 unit), serta bambu keriput (634 unit). Pada tahap Measure, digunakan alat bantu statistik berupa Peta Kendali-P yang menunjukkan bahwa proses produksi masih berada dalam batas kendali. Namun, hasil perhitungan menunjukkan nilai DPMO (Defect Per Million Opportunities) sebesar 15.566 dan level sigma sebesar 3,66, yang menandakan bahwa proses belum mencapai target kualitas yang diharapkan. Melalui analisis menggunakan diagram Pareto dan diagram fishbone, ditemukan bahwa penyebab utama kecacatan berasal dari lima faktor, yaitu: manusia, mesin, metode, material, dan lingkungan. Upaya perbaikan dilakukan melalui pendekatan 5W + 1H dengan fokus pada pelatihan operator, penerapan SOP secara konsisten, perawatan mesin berkala, seleksi bahan baku yang lebih ketat, serta perbaikan kondisi lingkungan kerja. Diharapkan perbaikan ini mampu menurunkan tingkat kecacatan dan meningkatkan efisiensi serta kualitas produk panel bambu di PT Dekor Asia Jayakarya Kata kunci: Six Sigma, DMAIC, Kontrol Kualitas, Panel Bambu, DPMO, Level Sigma ABSTRACT This study aims to analyze the quality control of bamboo panel products at PT Dekor Asia Jayakarya using the Six Sigma method through the DMAIC (Define, Measure, Analyze, Improve and Control) approach. During the period of 2024 to 2025, the company produced 41,290 units of bamboo panels, with 2,541 defective products, or equivalent to a defect rate of 6%. This value exceeds the company's quality standard of a maximum of 3.5%. The most common types of defects found include broken construction (641 units), moldy bamboo (624 units), loose nails and ropes (642 units), and wrinkled bamboo (634 units). At the Measure stage, a statistical tool in the form of a P-Control Chart was used, which showed that the production process was still within control limits. However, the calculation results showed a DPMO (Defect Per Million Opportunities) value of 15,566 and a sigma level of 3.66, which indicates that the process has not reached the expected quality target. Through analysis using Pareto charts and fishbone diagrams, it was discovered that the main causes of defects stem from five factors: people, machines, methods, materials, and the environment. Improvement efforts were carried out using the 5W + 1H approach, focusing on operator training, consistent implementation of SOPs, regular machine maintenance, stricter raw material selection, and improved work environment conditions. These improvements are expected to reduce the defect rate and increase the efficiency and quality of bamboo panel products at PT Dekor Asia Jayakarya. Keywords: Six Sigma, DMAIC, Quality Control, Bamboo Panels, DPMO, Sigma Level
