Abstract
UD Amanah merupakan salah satu perusahaan yang bergerak dalam bidang furniture yang memproduksi kerangka spring bed bertempat di Desa Lebo, Sidoarjo. Kayu adalah salah satu bagian penting dalam pembuatan produk kerangka spring bed dimana merupakan bahan baku utama dalam pembuatan kerangka. Produk Kerangka ini merupakan produk dengan permintaan yang paling tinggi, maka dibutuhkan analisa pengendalian kualitas yang tepat. Tujuan penelitian ini yaitu untuk menganalisa bagaimana cara mengurangi produk cacat pada kayu yang digunakan dalam proses produksi di UD Amanah. Salah satu metode yang digunakan pada penelitian ini adalah Plan-Do-check-Action (PDCA) dengan menggabungkan beberapa perangkat statistik lainnya berupa diagram Pareto dan Sebab-Akibat (Fishbone) pada tahap Plan, 5W + 1H pada tahap Do, Multivariate Exponentially Weighted Moving Average (MEWMA) pada tahap Check, dan dilakukan evaluasi kembali pada tahap Action. Dari hasil analisa dan pembahasan, menunjukkan jenis defect yang paling dominan yaitu ShortMold. Sedangkan dalam penerapan diagram kontrol MEWMA dari karakteristik kualitas kayu yaitu panjang dan lebar didapatkan bahwa rata-rata untuk proses pembentukan kerangka spring bed di UD Amanah pada bulan Desember 2020-Februari 2021 dalam keadaan tidak terkontrol dan yang lebih sensitif menggunakan pembobot λ sebesar 0.7

UD Amanah is one of the companies engaged in the furniture sector that produces spring bed frames located in Lebo Village, Sidoarjo. Wood is one of the important parts in the manufacture of spring bed frame products which is the main raw material in making the frame. This framework product is a product with the highest demand, so proper quality control is needed. The purpose of this study is to analyze how to reduce defective products in the wood used in the production process at UD Amanah. One of the methods used in this research is Plan-Do-check-Action (PDCA) by combining several other statistical tools in the form of Pareto and Cause-and-Effect (Fishbone) diagrams at the Plan stage, 5W + 1H at the Do stage, Multivariate Exponentially Weighted Moving Average (MEWMA) at the Check stage, and an evaluation is carried out at the Action stage. From the results of the analysis and discussion, it shows that the most dominant type of defect is ShortMold. Meanwhile, in the application of the MEWMA control chart of the wood quality characteristics, namely length and width, it was found that the average for the process of forming the spring bed frame at UD Amanah in December 2020-February 2021 was in an uncontrolled state and the more sensitive one was using a weight of 0.7
